OFFICE OF THE COUNTY ATTORNEY MEMORANDUM TO: Anthony P. Pires,Jr., Esq., Chairman Coastal Advisory Committee Clam Bay Subcommittee FROM: Colleen M. Greene, Assistant County Attorne C.n(1(r DATE: March 18,2010 RE: Sunshine Law and Agenda question The issue presented is whether the Sunshine Law requires that an agenda be made available prior to board meetings. In summary,the answer is no. The Sunshine Law Manual(2009 Ed. Vol. 31)provides the following: The Attorney General's Office recommends publication of an agenda, if available, in the notice of the meeting;. if an agenda is not available, subject matter summations might be used. However, the courts have held that the Sunshine Law does not mandate that an agency provide notice of each item to be discussed via a published agenda. Such a specific requirement has been rejected because it could effectively preclude access to meetings by members of the general public who wish to bring specific issues before a governmental body. See Hough v. Stembridge, 278 So. 2d 288 (Fla. 3d DCA 1973). And see Yarbrough v. Young, 462 So. 2d 515 (Fla. 1st DCA 1985) (posted agenda unnecessary; public body not required to postpone meeting due to inaccurate press report which was not part of the public body's official notice efforts). Thus, the Sunshine Law has been interpreted to require notice of meetings, not of the individual items which may be considered at that meeting. However, other statutes, codes or ordinances may impose such a requirement and agencies subject to those provisions must follow them. Accordingly, the Sunshine Law does not require boards to consider only those matters on a published agenda. "[W]hether to impose a requirement that restricts every relevant commission or board from considering matters not on an agenda is a policy decision to be made by the legislature." Law and Information Services, Inc. v. City of Riviera Beach, 670 So. 2d 1014, 1016 (Fla. 4th DCA 1996). Today's Coastal Advisory Committee Clam Bay Subcommittee was properly noticed in compliance with the Sunshine Law on or about February 1, 2010. Further, the agenda for today's meeting was also publically noticed on the County's website on Monday, March 15, 2010. The related back-up materials for the agenda were supplemented and available on the County's website on Wednesday, March 17, 2010. In addition, a number of these materials also appeared on the agenda for the Coastal Advisory Committee meeting on Thursday, March 11, 2010. In my opinion, there is no violation of the Sunshine Law and no legal issue regarding the date the agenda was published. cc: Gary McAlpin, Director, Coastal Zone Management Co 16T County Public Services division Coastal Zone Management TO: CAC Board Members FROM: Gail Hambright, Accountant DATE: December 1, 2012 SUBJECT: 2013 CAC Scheduled Meetings Please mark your calendar for the following 2013 CAC scheduled meeting dates: January 10, 2013 February 14,2013 March 14,2013 April 11, 2013 May 9, 2013 June 13, 2013 July 11, 2013 August 8, 2013 September 12, 2013 October 10, 2013 November 14, 2013 December 12, 2013 All meetings will be held in the Board of County Commissioner's chambers,third floor, Collier County Government Center, 3299 Tamiami Trail East, Naples, unless otherwise noted.

The time to mobilize and complete the work will be considered along with bid price in award; therefore,be specific. Cavache's proposed method of project completion: At receipt of notice to proceed Cavache will have survey and engineering work ordered for pre-survey, as well as begin immediate transport of the"Maya Caelyn" a 2010,16"Cutter head Ellicott 1170 custom dredge, dredge tenders, and support equipment to Marco Island staging area and to a near by Marina for assembly. Please see added attachment of dredge specifications. Cavache will set up an embankment area crew for installing a safety fence, signage, lights and a safe work zone. The crew will begin fusing and assembling pipeline, lights and signage, as well as, preparing beach area for embankment. During the same time, Cavache's second crew will be assembling the dredge and stern carriage barge and moving the dredge into the borrow area cut. Pipeline will be strung and ready for attachment. Dredge operations will begin after the pipeline is attached to dredge and all safety inspections and operational drills have been completed. Dredge operation will be 24/7 until all beach embankments have been completed and surveyed. Dredge operations will start on the east end of the Borrow area moving west. Dredge anchors will be set with one of the dredge tender boats as the dredge advances forward. Beach pipeline will be added as needed between shifts. Dredged spoil will start on the southern limits of the fill area and move to the north as dredge embankment is made, crew will finish grading the beach behind the dredge discharge. When embankment and survey have been completed, crew will begin demobilization of • dredge pipeline, materials and support equipment from the project. Cavache will then remove all safety equipment and fencing. Pipeline and dredge will be marked per the USCG Rules. Dredge is equipped with a spud carriage barge, a HYPACK real time GPS computer system and a flow&velocity meter to maximize operation efficiencies and production. The borrow area will be monitored with the on board HYPACK GPS real time position system as well as the dredge crew. In the event that the entire borrow area is affected with a heavy concentration of shell hash and moving the dredge does not offer a viable solution; Cavache can mobilize a specialized,hydraulic, dredge dead screen to the job to filter the shell hash and can speak to the owner about the option should the problem occur. This screen option should not impact the schedule. CAC January 10,2013 VII-3 Staff Reports 35 of 65 B)What size dredge do you propose for the work?

Johnson To: Interested Bidders Subject: Addendum#2 Solicitation#and Title 13-6009 South Marco Beach Sand Re-nourishment Project The following clarifications are issued as an addendum identifying the following change (s) for the referenced solicitation: Questions and Answers: Question: The following quote is located in the DEP permit, "During excavation and fill placement activities, Collier County's On-Site Representative will collect a sediment sample at not less than 500-foot intervals of newly constructed berm and prior to completion of the next 500-ft section to visually assess grain size, Munsell color, shell content, and silt content." A similar requirement is in the Technical Specifications, but the responsible party is the contractor. Is this a requirement of both the owner and contractor, and if so, why the redundancy? Would it be more prudent to allow the owner to test solely as it is required by the permit? Response: The County is requiring the Contractor to conduct the permit required sediment sampling and testing as stated in 11.7.9. Question: The technical specifications state substantial completion is 90 days, but other areas of the specifications state 60 days. Please clarify. Response: The Contract Time has been changed to the following. All references AddendumTemplate Revised:4/15/10 1 CAC January 10,2013 VII-3 Staff Reports 61 of 65 within the Bid Documents to 60 days, 90 days, dates of Substantial Completion, and dates of Final Completion shall be changed according to the following. CONTRACT TIME: February 12, 2013: Issue Notice of Award February 26, 2013: Issue Notice to Proceed April 1, 2013: Substantial Completion of Beach Fill Template, Stations 1488+00 to 1481+00 April 27, 2013: Substantial Completion of Beach Fill Template, Stations 1481+00 to 1461+00, subject to the Environmental Window defined in TS-XX. May 12, 2013: Final Completion Question: Is beach tilling a requirement of this contract upon completion of the dredging? Response: No. The County shall conduct the required beach tilling between April 28th and April 30th to comply with the Environmental Window. Question: I see there is a requirement to have a minimum of a 14 inch ID discharge on the dredge that will be used on this project. The dredge we have available has a 14 inch OD discharge. This is the same equipment we used on the Estero Island Beach project and the Blind Pass dredging project. Both projects were finished on time. Can you change specifications to consider past performance to allow our equipment to be used? Response: The requirement remains the same as specified in the Bid Documents, that being having a minimum of a 14 inch discharge line (Interior Diameter). Question: "Of special note is the Permit requirement for the maximum shell content equal to 5% retained on the #4 sieve. The CONTRACTOR shall utilize best management practices to implement the requirements of the Permits and avoid placing shell hash in excess of state standards." It should be noted that the contractor has very little control as to what comes out of the pipe. The borrow area is established, therefore, whatever material is in the borrow is what will be placed on the beach. We assume the owner has investigated and tested the borrow source to ensure that it is acceptable for beach nourishment. If an unacceptable amount of shell and/or shell hash is placed on the beach, and the contractor has dredged within the permitted borrow template, the mitigation cost should be paid by the owner. We consider placing this risk on the contractor to be unreasonable. The specifications need to address responsibility, regardless of the perceived likelihood of this occurring. Please consider an amendment clarifying the liability CAC January 10,2013 VII-3 Staff Reports 62 of 65 of placing "unsuitable" material on the beach so that we have comfort in bidding this project. Response: The intent of this section is to notify the County inspector on site so that the cutterhead dredge can be moved in the borrow area to avoid that pocket of shell hash, if significant. The County and Engineer working cooperatively with the Contractor and will make that decision. The County wants cooperation from the Contractor to move the dredging operation in the borrow area if required. While the County does not expect to encounter significant quantities of shell hash, the County must have the Contractor's cooperation. Remember, that this borrow area has been used many times in the past but there might be small pockets of shell hash. If the Contractor abides by the Permits and cooperates fully with the County, if the County wants to have shell hash removed from the beach or re-spread the shell hash within the Work area, the mitigation costs will be paid for by the County. The County expects the relocation of the dredge in the borrow area will be at the Contractor's expense. Question: "The CONTRACTOR must own the cutterhead-suction dredge having a minimum of a 14 inch discharge line (Interior Diameter) to be utilized on this Project. The Bidder must have demonstrated experience with this dredge on the successful completion of a minimum of three (3) similar projects." We have a long history in beach nourishment and have several dredges that can meet this requirement, but we have one particular dredge that we purchased in 2010. It has worked on one similar project, but does meet all other requirements. Please consider an amendment clarifying this language. Response: If the dredge the Contractor is proposing has a minimum of a 14 inch discharge line (Interior Diameter) as defined by the specifications, and the Contractor's company and site supervisor have experience using this or similar Contractor owned equipment; and the only issue is that this particular dredge has only been in the Contractor's inventory for 2 years, then that meets the intent of the specifications and the Contractor's proposal to use this equipment would be deemed acceptable subject to the other terms and conditions of the Contract Documents. Question: The USAGE permit requires turbidity testing every 6 hours while dredging. The DEP permit requires turbidity testing 2 times daily, at least 4 hours apart. Please clarify which is correct. Response: Turbidity monitoring shall be conducted by the Contractor in accordance with DEP Permit No. 0235209-003-JC dated October 11, 2012. Specific Conditions 32 through 34 contain the provisions including monitoring twice daily at least 4 hours apart. GENERAL ITEMS CAC January 10,2013 VII-3 Staff Reports 63 of 65 1.

Specifically, the COUNTY is seeking post-storm recovery funding from FEMA for impacts associated with Tropical Storm Debby. At its sole discretion, the County reserves the right to authorize excavation of an additional 15,000 cubic yards of beach compatible sediment from the permitted borrow area limits and placement of the sediment within the permitted fill limits as part of this CONTRACT. The option to or not to authorize the placement of the additional sediment shall not be a basis for claim for additional time or money. All provisions of the CONTRACT specific to the base bid fill quantity are applicable to the optional bid fill quantity.

Issuance Date: January 2, 2013 2481 NW Boca Raton Blvd. Boca Raton, FL 33431 Expiration Date: January 2, 2023 REGULATORY AUTHORIZATION: This permit is issued under the authority of Chapter 161 and Part IV of Chapter 373, Florida Statutes(F.S.), and Title 62, Florida Administrative Code (F.A.C.). Pursuant to Operating Agreements executed between the Department of Environmental Protection (Department) and the water management districts, as referenced in Chapter 62-113, F.A.C., the Department is responsible for reviewing and taking final agency action on this activity. PROJECT DESCRIPTION: The project is to straighten and expand the Wiggins Pass navigation channel by dredging a new alignment and filling the existing channel meander within the flood shoal. The dredged sand from the initial realignment will be placed in the flood shoal channel meander (Flood Shoal Disposal Area), the South Point Escarpment Repair site,the North Onshore Disposal Area and the North Nearshore Disposal Area. Any additional suitable dredge material available after those areas are filled will be placed in the Ebb Shoal Disposal Area. Approximately 7,500 cubic yards of material dredged from the realigned channel is not environmentally suitable for beach, nearshore or inlet disposal; so this material will be placed in a separate offshore disposal area (excavated basin of Borrow Area 6, from the 1996 Collier County beach restoration project). Periodic maintenance dredging of the authorized navigation channel location, including the north, south and east tributary channels, may also be conducted. A projected volume of approximately 50,000 cubic yards of beach-compatible sand may be dredged during each maintenance project and placed in one or more of the authorized disposal areas, including the CAC January 10,2013 VII-4 Staff Reports 2 of 26 Joint Coastal Permit Wiggins Pass Navigation Channel Expansion and Maintenance Permit No. 0142538-008-JC Page 2 of 26 South Onshore Disposal Area and the South Nearshore Disposal Area. Interim maintenance dredging projects may be conducted to remove smaller amounts of sand from the channel. Based on beach and inlet monitoring surveys, the dredged material will be distributed to the disposal areas in order to balance the sediment budget between the inlet and the adjacent shorelines, offset erosion of the adjacent shorelines, and maintain the location and hydraulic stability of the navigation channel. The proposed variance (File No. 0142538-013-BV) from Rule 62-4.244(5)(c), F.A.C., would temporarily establish expanded mixing zones at the dredging sites that extend 300 meters downcurrent from the turbidity source, or to the edge of the nearest seagrass bed, whichever is closer. The requested variance from the anti-degradation provisions in Rule 62-4.242(2)(a)2.b., F.A.C., would establish a maximum allowable turbidity level of 10 NTUs above background for work within OFW. PROJECT LOCATION: The dredge sites are located within Wiggins Pass, South Channel and the Gulf of Mexico. The nearshore and beach disposal sites are located north of the inlet, between DEP Reference monuments R-12 to R-15.5, and south of the inlet, between R-18 and R-20. The ebb shoal disposal area is located offshore of Wiggins Pass, approximately 300-1000 feet north of the authorized inlet channel. The South Point Escarpment Repair site is located on the beach, at the southern end of Barefoot Beach Preserve. The Flood Shoal Disposal Area is a portion of the meandered channel, located within Wiggins Pass, on the northern side of the new channel. The entire project is located in Collier County, Sections 17 and 20, Township 48 South, Range 25 East, Gulf of Mexico, Class III Waters. Portions of the project are within Outstanding Florida Waters associated with Barefoot Beach Preserve, Delnor-Wiggins Pass State Park and Wiggins Pass Estuarine Area and Cocohatchee River System. PROPRIETARY AUTHORIZATION: This activity also requires a proprietary authorization, as the activity is located on sovereign submerged lands held in trust by the Board of Trustees of the Internal Improvement Trust Fund (Board of Trustees), pursuant to Article X, Section 11 of the Florida Constitution, and Sections 253.002 and 253.77, F.S. The activity is not exempt from the need to obtain a proprietary authorization. The Board of Trustees delegated,to the Department,the responsibility to review and take final action on this request for proprietary authorization in accordance with Section 18-21.0051, F.A.C., and the Operating Agreements executed between the Department and the water management districts, as referenced in Chapter 62-113, F.A.C.

Protection of Historical Resources. If sand is to be placed on the beach of Delnor Wiggins State Park,then the following conditions apply for the protection of historical resources: a. Because of the lack of site information for 8CR970, Delnor Wiggins Pass State Park Site, the Division of Historical Resources requires that a Phase II level cultural resource site assessment be conducted at the recorded site location to determine if the site is an archaeological site or an isolated find. In the case of an archeological site, sufficient testing should be conducted to determine the extent of the site, the eligibility for listing in the National Register of Historic Places, and/or if it is otherwise of archaeological value. This must occur before any sand can be placed at this location. b. If there is an archaeological resource, and this site is determined to meet National Register criteria, or is otherwise of archaeological value, further consultation with the Division of Historical Resources,the Department's Beaches, Inlets and Ports CAC January 10,2013 VII-4 Staff Reports 9 of 26 Joint Coastal Permit Wiggins Pass Navigation Channel Expansion and Maintenance Permit No. 0142538-008-JC Page 9 of 26 program and Delnor Wiggins Pass State Park cultural programs must occur to determine measures to avoid and/or minimize any effects to the site. c. Site 8CR218, Wiggins Pass Wreck South, must be located, GPS coordinates obtained, and the depth of deposits determined. The extent of the historic wreck site and an adequate buffer area should be clearly delineated on all project maps and on the ground during construction. This site must be avoided during beach nourishment activities associated with this permit, due to the nature and location of the site making it unable to be investigated, as well as the possibility that this site may be eligible for listing in the National Register. This includes all ground disturbing activities and heavy equipment operation associated with the initial placement of dredge material on the beach, and the subsequent annual tilling required a month prior to turtle nesting season. 8. Additional Coastal Engineering Condition. After the dredging Subarea D(channel realignment through the flood shoal, between C-3 and C-16) is completed, the Contractor shall be allowed to begin work in multiple subareas and to alternate between subareas. Once the Pemittee/Owner's Representative authorizes removal of the unsuitable material to begin from within a specified subarea(i.e., dredging of the suitable material has reached the threshold elevation), no additional material from within the specified subarea shall be allowed for beach or nearshore placement from that subarea. Material designated for beach, nearshore, ebb and flood shoal placement, as shown in the permit drawings, may be pumped directly to the respective placement site. The material designated for offshore disposal shall be placed in a barge for transport to the offshore disposal site at Borrow Area 6. A threshold elevation is identified for each subarea that contains clay, peat, silty sand (with silt content exceeding the sand standards in Rule 62B-41.007(2)(j), F.A.C.), or rock material. The Contractor shall be provided a tolerance above the threshold elevation for excavating material for beach or nearshore placement. The tolerance shall serve as a transition layer(overdredge allowance)between the material designated for beach or nearshore placement and the material that must be disposed as unsuitable material. The threshold elevation shall serve as a definitive line between the unsuitable material and the tolerance. 9. Sediment quality shall be assessed as outlined in the Sediment QA/QC plan dated July 3, 2012 (attached) for the initial construction. Any occurrences of placement of material not in compliance with the Plan shall be handled according to the protocols set forth in the Sediment QA/QC plan. The sediment testing result will be submitted to the Department within 90 days following the completion of beach construction. The Sediment QC/QA plan includes the following: CAC January 10,2013 VII-4 Staff Reports 10 of 26 Joint Coastal Permit Wiggins Pass Navigation Channel Expansion and Maintenance Permit No. 0142538-008-JC Page 10 of 26 a. If during construction, the Permittee or Engineer determines that the beach fill material does not comply with the sediment compliance specifications, measures shall be taken to avoid further placement of noncompliant fill, and the sediment inspection results shall be reported to the Department. b. The Permittee shall submit post-construction sediment testing results and an analysis report as outlined in the Sediment QC/QA plan to the Department within 90 days following beach construction. The sediment testing results shall be certified by a P.E. or P.G. from the testing laboratory. A summary table of the sediment samples and test results for the sediment compliance parameters as outlined in Table 1 of the Sediment QC/QA plan shall accompany the complete set of laboratory testing results. A statement of how the placed fill material compares to the sediment analysis and volume calculations from the geotechnical investigation shall be included in the sediment testing results report. c. A post-remediation report containing the site map, sediment analysis, and volume of noncompliant fill material removed and replaced will be submitted to the Department within 7 days following completion of remediation activities. Prior to each maintenance dredge event, the sediment quality of the material to be dredged (after the initial dredge event)must be determined. The material must be tested and reviewed for beach compatibility. A Maintenance Dredging Sediment QA/QA plan shall be submitted with the final construction plans and specifications for subsequent maintenance dredging activities, and it shall include compliance values that are consistent with Rule 62B-41.007(2)(k), F.A.C. Manatee,Marine Turtle,and Shorebird Protection Conditions 10. During all construction authorized by this permit and subsequent to authorization of incidental take by the National Marine Fisheries Service (NMFS) and the U.S. Fish and Wildlife Service(Service) in accordance with Florida Statute 161.041 (5), 379.2431 (1), the Permittee shall comply with the following conditions intended to protect manatees, marine turtles and shorebirds from direct project effects: a. All personnel associated with the project shall be instructed about the presence of marine turtles, manatees and manatee speed zones, and the need to avoid collisions with (and injury to)these protected marine species.

Bird Monitors shall use the following survey protocols: a. Bird Monitors shall review and become familiar with the general information, employ the data collection protocol, and implement data entry procedures outlined on the FWC's Florida Shorebird Database (FSD)website (www.Fl,ShorebirdDatabase.org). An outline of data to be collected, including downloadable field data sheets, is available on the website. b. Breeding season varies by species. Most species have completed the breeding cycle by September 1, but flightless young may be present through September. The following dates are based on the best available information regarding ranges and habitat use by species around the state: All Gulf Coast counties: February 15 —September 1 Breeding season surveys shall begin on the first day of the breeding season or 10 days prior to project commencement(including surveying activities and other pre- construction presence on the beach), whichever is later. Surveys shall be conducted through August 31st or until all breeding activity has concluded, whichever is later. c. Breeding season surveys shall be conducted in all potential beach-nesting bird habitats within the project boundaries that may be impacted by construction or pre-construction activities. Portions of the project in which there is no potential for project-related activity during the nesting season may be excluded. One or more shorebird survey routes shall be established in the FSD website to cover these areas. d. During the pre-construction and construction phases of the project, surveys for detecting breeding activity and the presence of flightless chicks will be completed on a daily basis prior to movement of equipment, operation of vehicles, or other activities that could potentially disrupt breeding behavior or cause harm to the birds or their eggs or young. e. Surveys shall be conducted by walking the length of the project area and visually surveying for the presence of shorebirds exhibiting breeding behavior, shorebird/seabird chicks, or shorebird/seabird juveniles as outlined in the FSD Breeding Bird Protocol for Shorebirds and Seabirds. Use of binoculars is required. i. If an ATV or other vehicle is needed to cover large project areas, operators will adhere to the FWC's Best Management Practices for Operating Vehicles on the Beach (http://mvfwc.com/conservation/vou- CAC January 10,2013 VII-4 Staff Reports 15 of 26 Joint Coastal Permit Wiggins Pass Navigation Channel Expansion and Maintenance Permit No. 0142538-008-JC Page 15 of 26 conserve/wildlifelbeach-driving). Specifically,the vehicle must be operated at a speed <6 mph and run at or below the high-tide line. The Bird Monitor will stop at no greater than 200 meter intervals to visually inspect for breeding activity. f. Once breeding is confirmed by the presence of a scrape, eggs, or young,the Bird Monitor will notify the FWC Regional Species Conservation Biologist(contact information attached) within 24 hours. All breeding activity will be reported to the FSD website within one week of data collection. 16. Seabird and Shorebird Buffer Zones and Travel Corridors. Within the project area, the permittee shall establish a disturbance-free buffer zone around any location where shorebirds have been engaged in breeding behavior, including territory defense. A 300 ft-wide buffer is considered adequate based on published studies. However, a smaller, site-specific buffer may be implemented upon approval by the FWC Regional Species Conservation Biologist(contact information attached) as needed. All sources of human disturbance(including pedestrians, pets, and vehicles) shall be prohibited in the buffer zone. a. The Bird Monitor shall keep breeding sites under sufficient surveillance to determine if birds appear agitated or disturbed by construction or other activities in adjacent areas. If birds do appear to be agitated or disturbed by these activities, then the width of the buffer zone shall be increased immediately to a sufficient size to protect breeding birds. b. Reasonable and traditional pedestrian access should not be blocked where breeding birds will tolerate pedestrian traffic. This is generally the case with lateral movement of beach-goers walking parallel to the beach at or below the highest tide line. Pedestrian traffic may also be tolerated when breeding was initiated within 300 feet of an established beach access pathway. The Permittee shall work with the FWC Regional Species Biologist to determine if pedestrian access can be accommodated without compromising nesting success. c. Designated buffer zones must be marked with posts, twine, and signs stating"Do Not Enter, Important Nesting Area"or similar language around the perimeter which includes the name and a phone number of the entity responsible for posting. Posts should not exceed 3' in height once installed. Symbolic fencing (twine, string, or rope) should be placed between all posts at least 2.5' above the ground and rendered clearly visible to pedestrians. If pedestrian pathways are approved by the FWC Regional Species Conservation Biologist within the 300- foot buffer zone, these should be clearly marked. The posting shall be maintained in good repair until breeding is completed or terminated. Although solitary nesters may leave the buffer zone with their chicks,the posted area CAC January 10,2013 VII-4 Staff Reports 16 of 26 Joint Coastal Permit Wiggins Pass Navigation Channel Expansion and Maintenance Permit No. 0142538-008-JC Page 16 of 26 continues to provide a potential refuge for the family until breeding is complete. Breeding is not considered to be completed until all chicks have fledged. d. No construction activities, pedestrians, movement of vehicles, or stockpiling of equipment shall be allowed within the buffer area. e. Travel corridors shall be designated and marked outside the buffer areas so as not to cause disturbance to breeding birds. Heavy equipment, other vehicles, or pedestrians may transit past breeding areas in these corridors. However, other activities such as stopping or turning shall be prohibited within the designated travel corridors adjacent to the breeding site. When flightless chicks are present within or adjacent to travel corridors, movement of vehicles shall be accompanied by the Bird Monitor who will ensure no chicks are in the path of the moving vehicle and no tracks capable of trapping flightless chicks result. f. To discourage nesting within the travel corridor, it is recommended that the Permittee should maintain some activity within these corridors on a daily basis, without disturbing any nesting shorebirds documented on site or interfering with sea turtle nesting, especially when those corridors are established prior to commencement of construction. 17. Notification. If shorebird breeding occurs within the project area, a bulletin board will be placed and maintained in the construction staging area with the location map of the construction site showing the bird breeding areas and a warning, clearly visible, stating that"NESTING BIRDS ARE PROTECTED BY LAW INCLUDING THE FLORIDA ENDANGERED AND THREATENED SPECIES ACT AND THE STATE and FEDERAL MIGRATORY BIRD ACTS". 18. Marine Turtle Nest Surveys and Relocation. All sand placement shall occur outside the marine turtle nesting season, May 1 through October 31. The following marine turtle protection conditions shall be met during such work; FWC may recommend incorporation of any additional terms and conditions specified in the federal incidental take authorization through modification prior to commencement of construction. Marine turtle nesting surveys shall be initiated 65 days prior to sand placement activities or by April 15 whichever is later and shall comply with the following requirements ones). a. Nesting surveys and nest marking will only be conducted by persons with prior experience and training in these activities and who are authorized to conduct such activities through a valid permit issued by FWC, pursuant to FAC 68E-1. Please contact FWC's Marine Turtle Management Program in Tequesta at MTP @myfwc.com, for information on the permit holder in the project area. Nesting surveys shall be conducted daily between sunrise and 9 a.m. (this is for all time zones). The contractor shall not initiate work until daily notice has been CAC January 10,2013 VII-4 Staff Reports 17 of 26 Joint Coastal Permit Wiggins Pass Navigation Channel Expansion and Maintenance Permit No. 0142538-008-JC Page 17 of 26 received from the marine turtle permit holder that the morning survey has been completed. Surveys shall be performed in such a manner so as to ensure that construction activity does not occur in any location prior to completion of the necessary marine turtle protection measures. b. Nests shall be left in place and marked for avoidance unless other factors threaten the success of the nest(nest laid below debris line marking the typical high tide, erosion). The Marine Turtle Permit Holder shall install an on-beach marker at the nest site and a secondary marker at a point as far landward as possible to assure that future location of the nest will be possible should the on-beach marker be lost. The actual location of the clutch will be determined and nests will be marked. A series of stakes and highly visible survey ribbon or string shall be installed to establish a three-foot radius around the nest. No activity shall occur within this area nor will any activity occur that could result in impacts to the nest. Nest sites shall be inspected daily to assure nest markers remain in place and that the nest has not been disturbed by the project activity. Nest relocation is only allowed if nests laid within the travel corridor(beach access to MHWL) cannot be rerouted to avoid the nest. 19. To the maximum extent possible within the travel corridor, all ruts shall be filled or leveled to the natural beach profile prior to completion of daily construction during shorebird nesting season. 20. If entrapment of sea turtle hatchlings occurs in the groin or jetty system during construction, the permittee shall contact FWC immediately. 21. Marine Turtle or Nest Encounters. Upon locating a dead or injured sea turtle adult, hatchling or egg that may have been harmed or destroyed as a direct or indirect result of the project,the Corps, applicant, and/or local sponsor shall be responsible for notifying FWC Wildlife Alert at 1-888-404-FWCC (3922). Care shall be taken in handling injured sea turtles or eggs to ensure effective treatment or disposition, and in handling dead specimens to preserve biological materials in the best possible state for later analysis. In the event a sea turtle nest is excavated during construction activities,the permitted person responsible for egg relocation for the project shall be notified immediately so the eggs can be moved to a suitable relocation site. 22. Equipment Storage and Placement. All construction pipes that are placed on the beach shall be located as far landward as possible without compromising the integrity of the existing or reconstructed dune system. Pipes placed parallel to the dune shall be 5 to 10 feet away from the toe of the dune. Temporary storage of pipes shall be off the beach to the maximum extent possible. If it will be necessary to extend construction pipes past a known shorebird nesting site or over-wintering area for piping plovers, then whenever possible those pipes shall be placed landward of the site before birds are active in that CAC January 10,2013 VII-4 Staff Reports 18 of 26 Joint Coastal Permit Wiggins Pass Navigation Channel Expansion and Maintenance Permit No. 0142538-008-JC Page 18 of 26 area. No pipe or sand shall be placed seaward of a shorebird nesting site during the shorebird nesting season. 23. Compaction Sampling. Sand compaction shall be monitored in the area of sand placement immediately after completion of the project and prior to April 15th for three (3) subsequent years and shall be monitored in accordance with a protocol agreed to by the FWS, FWC, and the applicant or local sponsor. The requirement for compaction monitoring can be eliminated if the decision is made to till regardless of post-construction compaction levels. Out-year compaction monitoring and remediation are not required if placed material no longer remains on the beach. At a minimum,the protocol provided under a. and b. below shall be followed. If the average value for any depth exceeds 500 pounds per square inch (psi) for any two or more adjacent stations, then that area shall be tilled immediately prior to the following date listed above. If values exceeding 500 psi are distributed throughout the project area but in no case do those values exist at two adjacent stations at the same depth,then consultation with the FWC or FWS will be required to determine if tilling is required. If a few values exceeding 500 psi are present randomly within the project area,tilling will not be required. a. Compaction sampling stations shall be located at 500-foot intervals along the project area. One station shall be at the seaward edge of the dune/bulkhead line (when material is placed in this area), and one station shall be midway between the dune line and the high water line (normal wrack line). b. At each station, the cone penetrometer shall be pushed to a depth of 6, 12, and 18 inches three times (three replicates). Material may be removed from the hole if necessary to ensure accurate readings of successive levels of sediment. The penetrometer may need to be reset between pushes, especially if sediment layering exists. Layers of highly compact material may lie over less compact layers. Replicates shall be located as close to each other as possible, without interacting with the previous hole and/or disturbed sediments. The three replicate compaction values for each depth shall be averaged to produce final values for each depth at each station. Reports will include all 18 values for each transect line, and the final 6 averaged compaction values. c. No compaction sampling shall occur within 300 feet of any shorebird nest. d. Any vehicles operated on the beach in association with compaction surveys shall operate in accordance with the FWC's Best Management Practices for Operating Vehicles on the Beach (http://myfwc.com/conservation/you- conserve/wildlife/beach-driving!). CAC January 10,2013 VII-4 Staff Reports 19 of 26 Joint Coastal Permit Wiggins Pass Navigation Channel Expansion and Maintenance Permit No. 0142538-008-JC Page 19 of 26 24. Tilling Requirements. If tilling is required as specified above,the area shall be tilled to a depth of 36 inches. All tilling activity shall be completed prior to the marine turtle nesting season. If tilling occurs during shorebird nesting season (See 15b above), shorebird surveys prior to tilling shall be required per the Shorebird Conditions included within this document. It is the responsibility of the contractors to avoid tilling, scarp removal, or dune vegetation planting in areas where nesting birds are present. Each pass of the tilling equipment shall be overlapped to allow thorough and even tilling. If the project is completed during the marine turtle nesting season, tilling will not be performed in areas where nests have been left in place or relocated. If compaction measurements are taken, a report on the results of the compaction monitoring shall be submitted electronically to FWC at marineturtle @myfwc.com prior to any tilling actions being taken. a. No tilling shall occur within 300 feet of any shorebird nest. b. If flightless shorebird young are observed within the work zone or equipment travel corridor, a Shorebird Monitor shall be present during the operation to ensure that equipment does not operate within 300 feet of the flightless young. c. A relatively even surface, with no deep ruts or furrows, shall be created during tilling. To do this, chain-linked fencing or other material shall be dragged over those areas as necessary after tilling. d. Tilling shall occur landward of the wrack line and avoid all vegetated areas 3 square feet or greater with a 3 square foot buffer around the vegetated areas. The slope between the mean high water line and the mean low water line must be maintained in such a manner as to approximate natural slopes. e. Any vehicles operated on the beach in association with tilling shall operate in accordance with the FWC's Best Management Practices for Operating Vehicles on the Beach (http:/hn)/fwc.com/conservation/you-conserve/Wildlife/beach- driving/). 25. Escarpment Surveys. Visual surveys for escarpments along the project area shall be made immediately after completion of the sand placement project, weekly during sea turtle nesting season, and during March 15 to April 15 for three (3) subsequent years if sand from the project area still remains on the beach. Escarpments that interfere with sea turtle nesting or that exceed 18 inches in height for a distance of at least 100 feet shall be leveled and the beach profile shall be reconfigured to minimize scarp formation by April 15. Any escarpment removal shall be reported by location. If the project is completed during the sea turtle nesting and hatching season, escarpments may be required to be leveled immediately, while protecting nests that have been relocated or left in place. FWC shall be contacted immediately if subsequent CAC January 10,2013 VII-4 Staff Reports 20 of 26 Joint Coastal Permit Wiggins Pass Navigation Channel Expansion and Maintenance Permit No. 0142538-008-JC Page 20 of 26 reformation of escarpments that interfere with sea turtle nesting or that exceed 18 inches in height for a distance of 100 feet occurs during the nesting and hatching season to determine the appropriate action to be taken. If it is determined that escarpment leveling is required during the nesting or hatching season, the FWS or FWC will provide a brief written authorization that describes methods to be used to reduce the likelihood of impacting existing nests. An annual summary of escarpment surveys and actions taken shall be submitted electronically to marineturtlercOlvfwc.com along with the annual summary as described below. If escarpment removal occurs during shorebird breeding season (See 16b), shorebirds surveys shall be required per the Shorebird Conditions included within this document prior to removal. (NOTE: Out-year escarpment monitoring and remediation are not required if placed material no longer remains on the dry beach). a. No heavy equipment shall operate within 300 feet of any shorebird nest. b. If flightless shorebird young are observed within the work zone or equipment travel corridor, a Shorebird Monitor shall be present during the operation to ensure that equipment does not operate within 300 feet of the flightless young. c. Any vehicles operated on the beach in association with escarpment surveys or removal shall operate in accordance with the FWC's Best Management Practices for Operating Vehicles on the Beach (http://myfwc.com/conservation/vou- conserve/wildlife/beach-driving/). Post-construction Shorebird Protection Conditions: 26. If beach cleaning will occur on the nourished beach, a minimum of 30%of the biotic material within the wrack line will be left on the beach post-cleaning at the strand line in a natural configuration to ensure that the nourished beach re-establishes its function as foraging habitat for shorebirds. This shall occur for as long as the placed sand remains on the beach. Post-construction Monitoring and Reporting Marine Turtle Protection Conditions: 27. Reports on all marine turtle nesting activity shall be provided for the initial marine turtle nesting (May 1 through September 15) and hatching(through October 31) season and for up to three additional nesting seasons as follows: a. For the initial nesting season and the following year, the number and type of emergences (nests or false crawls) shall be reported per species in accordance with the Table below. An additional year of nesting surveys may be required if nesting success for any species on the nourished beach is less than 40%. CAC January 10,2013 VII-4 Staff Reports 21 of 26 Joint Coastal Permit Wiggins Pass Navigation Channel Expansion and Maintenance Permit No. 0142538-008-JC Page 21 of 26 b. For the initial nesting season, reproductive success shall be reported per species in accordance with the Table below. Reproductive success shall be reported for all sea turtle nests if possible. Otherwise a statistically significant number of nests for each species shall be reported. c. In the event that the reproductive success documented by species meets or exceeds required criteria(outlined in Table below) for each species, monitoring for reproductive success shall be recommended, but not required for the second year post-construction. d. Monitoring of nesting activity in the seasons following construction shall include daily surveys and any additional measures authorized by the FWC. Summaries shall include all crawl activity, nesting success rates, hatching success of all relocated nests, hatching success of a representative sampling of nests left in place (if any) by species, project name and applicable project permit numbers and dates of construction. Data should be reported for the nourished areas in accordance with the Table below and should include number of nests lost to erosion or washed out. Summaries of nesting activity shall be submitted in electronic format(Excel spreadsheets)to the FWC Imperiled Species Management section at MTI' bmylwc.com. All summaries should be submitted by January 15 of the following year. The FWC Excel spreadsheet is available upon request from MTP(a)myfwc.com.

The survey shall be conducted by the Permittee or local sponsor and should be conducted to include a landward view from the seaward most extent of the new beach profile. The survey should follow standard techniques for such a survey and include number and type of visible lights, location of lights and photo documentation. For each light source visible, it must be documented that the property owner(s) have been notified of the problem light with recommendations for correcting the light. Recommendations must be in accordance with the Florida Model Lighting Ordinance for Marine Turtle Protection CAC January 10,2013 VII-4 Staff Reports 23 of 26 Joint Coastal Permit Wiggins Pass Navigation Channel Expansion and Maintenance Permit No. 0142538-008-JC Page 23 of 26 (Chapter 62B-55, F.A.C.) and local lighting restrictions. In addition to local code enforcement, actions must be taken by the Permittee to ensure that no lights or light sources are visible from the newly elevated beach within their respective areas. A report summarizing all lights visible shall be submitted to FWC Imperiled Species Management Section at marineturtle(u?mvfwc.com by the 1st of the month following survey. A summary report documenting what corrective actions have been taken provided and all compliance and enforcement actions shall also be submitted by December 15 of that year. After the annual report is completed, a meeting shall be set up with the permittees or local sponsor, county or municipality, FWC and the FWS to discuss the survey report as well as any documented sea turtle disorientations in or adjacent to the project area. 29. Biological Opinion. In accordance with Section 161.041(5), F.S., no construction that could result in take of threatened and marine turtles shall begin until the federal incidental take authorization is issued in accordance with the federal Endangered Species Act. In the event that additional requirements are specified in any subsequent U.S. Fish and Wildlife Service Incidental Take Authorization and Biological Opinion, additional marine turtle protection conditions may be incorporated into this final order through a minor modification. MONITORING REQUIRED: 30. Water Quality. Turbidity shall be monitored during the dredging and placement (disposal) activities for this project as follows: Units: Nephelometric Turbidity Units(NTUs). Frequency: Approximately every 4 hours during dredging and disposal, while the maximum turbidity plume crosses the edge of the mixing zone. Location: Background: At least 500 meters upcurrent of both the dredging and disposal locations, outside the influence of any visible turbidity plume, at the surface and mid-depths. Compliance 1 (disposal sites): In the densest portion of the turbidity plume, downcurrent from the source of turbidity, at the surface and mid- depths, not more than 150 meters from the discharge point or at the location of the nearest hardbottom edge, whichever is less. Compliance 2 (dredge site): In the densest portion of the turbidity plume, downcurrent from the source of turbidity, at the surface and mid-depths, not more than 300 meters from the dredge cutterhead, or at the location of the nearest seagrass edge, whichever is less. CAC January 10,2013 VII-4 Staff Reports 24 of 26 Joint Coastal Permit Wiggins Pass Navigation Channel Expansion and Maintenance Permit No. 0142538-008-JC Page 24 of 26 The compliance locations given above shall be considered the limits of the temporary mixing zone for turbidity allowed during construction. Standards: Within OFW: When the mixing zone extends into OFW,turbidity at the compliance site shall not be greater than ten (10)NTUs above the corresponding background measurement. Outside OFW: At the edge of mixing zones terminating outside of OFW, compliance turbidity levels shall not be greater than 29 NTUs above the corresponding background measurement. Calibration: The instruments used to measure turbidity shall be fully calibrated within one month of the commencement of the project, and at least once a month throughout the project. Calibration shall be verified each morning prior to use, and after each time the instrument is turned on, using a turbidity "standard"that is different from the one used during calibration. 31. The compliance locations given above shall be considered the limits of the temporary mixing zone for turbidity allowed during construction. If monitoring reveals turbidity levels at the compliance sites that are greater than 29 NTUs above the corresponding background turbidity levels outside of OFW, or greater than 10 NTUs above background within OFWs, construction activities shall cease immediately and not resume until corrective measures have been taken and turbidity has returned to acceptable levels. Any such occurrence shall also be immediately reported to the Department's Compliance Officer via email at JCP Compliance; dep.state.fl.us,and include in the subject line, "TURBIDITY EXCEEDANCE", and the Project Name and Permit Number. Also notify the Department's South District office. Any project-associated discharge other than the approved dredging and placement(e.g., scow or pipeline leakage or runoff from temporary containment area) shall be monitored as close to the source as possible every hour until background turbidity levels return or until otherwise directed by the Department. The Permittee shall notify the Department, by separate email to the Compliance Officer, of such an event within 24 hours of the time the Permittee first becomes aware of the discharge. The subject line of the email shall state "PROJECT-ASSOCIATED DISCHARGE-OTHER", and include the Project Name and the Permit Number. TURBIDITY REPORTS 32.

This document will address potential effects of the proposed project on the threatened piping plover(Charadrius melodus),threatened loggerhead sea turtle(Caretta caretta),endangered leatherback sea turtle(Dermochelys coriacea), endangered green sea turtle(Chelonia mydas),endangered hawksbill sea turtle(Eretmochelys imbricata),endangered Kemp's ridley sea turtle(Lepidochelys kempii), and endangered West Indian manatee(Trichechus manatus). This document is provided in accordance with section 7 of the Endangered Species Act of 1973,as amended(Act) (87 Stat. 884; 16 U.S.C. 1531 et seq.). In the Corps' letter dated April 12,2012,the Corps did not make a determination concerning the piping plover in regard to the proposed project. That said,piping plovers have been documented within Bgr9199113eAch Prouty and optimal piping pinwr foraging and roosting habitat is present within the project area. Therefore,in an email dated September 19,2012,the Corps determined the proposed project"may affect"the piping plover and requested initiation of formal consultation. This Biological Opinion is based on information provided in the Corps' letter dated April 12,2012, Public Notice, supplemental documents,and correspondence with the Corps,National Oceanic Atmospheric Administration's National Marine Fisheries Service(NOAA Fisheries), and Florida Fish and Wildlife Conservation Commission(FWC). A complete administrative record of this consultation is on file at the South Florida Ecological Services Office, Vero Beach,Florida. TAKE PRIDE® 1NAM E RLCA.-�- CAC January 10,2013 VII-5 Staff Reports 2 of 64 FISH AND WILDLIFE RESOURCES Hardbottom Reef Habitat and Seagrasses The proposed project could affect approximately 15.8 acres within the Wiggins Pass dredge template. The Corps permit does not authorize impacts to seagrass or nearshore hardbottom habitat, and all dredging is restricted to unvegetated areas. There is no exposed hardbottom habitat located within or near the channels of Wiggins Pass or the designated disposal areas. The closest hardbottom resources are located approximately 240 and 530 feet west of the Delnor- Wiggins and Barefoot Beach disposal area, respectively. Seagrass has been observed along the shallow shelf lining the main navigation channel and within the shallow protected areas fringing the mangrove islands in the interior channels. Seagrass is not located within the dredge template or disposal areas. Whenever feasible, turbidity curtains will be utilized to protect seagrass and oyster beds in the vicinity of the project area during construction. No seagrass or hardbottom impacts are anticipated as a result of the proposed project,such as, but not limited to,propeller scouring, pipeline placement, vessel or barge anchoring, grounding, or spudding. Collier County Coastal Zone Management (Applicant) shall be liable for any unauthorized impacts. For any impacts caused by construction activities, seagrass or hardbottom restoration or mitigation may be required which will be coordinated through the Corps,NOAA Fisheries, and Service. The Corps will continue to consult with NOAA Fisheries, who will assess all potential effects to hardbottom reef habitat and seagrass within the dredge template, onshore sand placement fill template, and disposal areas. Consultation History On April 16, 2012, the Service received a copy of the Corps' letter dated April 12, 2012,and Public Notice concerning the proposed Wiggins Pass navigation channel maintenance dredging and sand placement project, Collier County, Florida. On June 25, 2012, the Service emailed the Corps a request for additional information. On July 10, 2012, the Service received the requested additional information from the consultant. On August 17, 2012, the Service emailed the Corps a second request for additional information. On August 21, 2012, the Service received the requested additional information from the consultant. On September 19, 2012, the Corps emailed the Service with a"may affect" determination for the piping plover and requested initiation of formal consultation. On September 25, 2012, the Service completed their review of the proposed project and initiated formal consultation with the Corps concerning the potential effects of the proposed project on piping plovers. CAC January 10,2013 VII-5 Staff Reports 3 of 64 BIOLOGICAL OPINION DESCRIPTION OF THE PROPOSED ACTION The Applicant proposes to conduct an initial realignment dredging and periodic maintenance dredging of accreted sand, shell, and sediment from the Wiggins Pass navigational channel, in Collier County, Florida (Figure 1). The proposed project includes channel realignment, which will be accomplished by straightening the inlet channel layout and infilling and blocking the northern flood shoal meander. Using a cutterhead or mechanical dredge, the navigational channel will be dredged to the authorized depths of-7.0 to -12.0 feet North American Vertical Datum of 1988,with a 1-foot overdredge. Beach compatible dredge material will be placed in nearshore and beach (onshore) disposal sites located north and south of the channel between Florida Department of Environmental Protection (DEP) reference monuments R-12 and R-15.5, and R-18 and R-20, respectively (Figure 1). All beach compatible dredge material placed within the beach disposal site will be graded to the permitted design fill profile using heavy equipment. All sand placed within the beach fill template must be approved by the DEP and meet all requirements as outlined in the Florida Administrative Code subsection 62B-41.007. An offshore disposal area(Borrow Area 6 from the 1996 beach nourishment project) has been designated as an acceptable location to place non-beach compatible dredge material. In addition, an ebb shoal disposal area has been designated to assist in stabilizing the Barefoot Beach shoreline (Figure 1). The designated dredge disposal locations and distribution will be modified and relocated based on shoreline monitoring results, with preference given to areas with greatest need. Additional components of the proposed project include scarp repair along southern Barefoot Beach to restore the beach to historic conditions and infilling and blocking the northern flood shoal meander. The flood shoal meander will be constructed with a 0.5-foot upper tolerance to account for settlement and consolidation of material post-placement. The east, north, and south interior channel entrances are identified for maintenance dredging should sand shoal within their respective boundaries. The intent of the proposed dredging action is to restore navigation depth and provide material for shoreline stabilization. All beach corridors, staging areas, and construction corridors will be selected to avoid affects to upland habitat. Construction vehicles and equipment must traverse or be stored within these designated areas,corridors, and/or within the pipeline corridor. In addition, all construction pipes will be placed parallel to the shoreline and positioned as far landward as possible up to the vegetated dune line. Equipment on the beach will only occur to support sand placement activities on the dry beach. Existing vegetated habitat at these sites and corridors shall be protected to the maximum extent practicable. Any affected vegetation at each of these sites and corridors shall be restored to preconstruction conditions, In addition, if heavy equipment and vehicles are required to traverse the dry beach above the mean high water line, the path will be tilled to a depth of 3 feet to avoid compaction effects prior to the following sea turtle nesting season. The initial dredging event is scheduled to occur in 2013, with additional maintenance dredging events every 4 years. The initial dredging event will involve removing approximately 95,000 cubic yards (cy),but may be greater or less depending upon present conditions. The anticipated maximum dredging volume for each maintenance dredging event will be approximately 50,000 cy. Intermediate ebb channel dredging events may need to take place, which will excavate 3 CAC January 10,2013 VII-5 Staff Reports 4 of 64 • between 8,000 and 10,000 cy and sidecast material to the north of the channel. The initial dredging event is anticipated to take 75 days. A typical maintenance dredging event is expected to be approximately 45 days in duration. Dredging and sand placement activities will take place 24 hours a day, 7 days a week. The proposed project area lies within Coastal Barrier Resources Act (CBRA) Unit FL-65P, Wiggins Pass. This unit is part of the Coastal Barrier Resources System (System) which supports suitable habitat for species listed under the Act. The purposes of CBRA are to minimize the loss of human life, wasteful expenditure of Federal revenues, and damage to fish, wildlife, and other natural resources associated with units of the System. Because there is no Federal funding allocated for the proposed project, there are no CBRA-related restrictions. Action area The action area is defined as all areas to be affected directly or indirectly by the action and not merely the immediate area involved in the action. The Service identifies the action area to include the dredge template, north and south onshore and nearshore fill templates (approximately 1.15 miles), offshore disposal area, flood shoal disposal area, ebb shoal disposal area, staging areas, and downdrift area. The project is located along the Gulf of Mexico, in Collier County, Florida, at latitude 26.2884 and longitude-81.8312. STATUS OF THE SPECIES/CRITICAL HABITAT Species/critical habitat description The piping plover is a small,pale sand-colored shorebird, about 7 inches long with a wingspan of about 15 inches (Palmer 1967). On January 10, 1986,the piping plover was listed as endangered in the Great Lakes watershed and threatened elsewhere within its range,including migratory routes outside of the Great Lakes watershed and wintering grounds(Service 1985). Piping plovers were listed principally because of habitat destruction and degradation,predation,and human disturbance. Protection of the species under the Act reflects the species' precarious status range-wide. Three separate breeding populations have been identified, each with its own recovery criteria: the northern Great Plains (threatened),the Great Lakes (endangered), and the Atlantic Coast (threatened). The piping plover winters in coastal areas of the U.S. from North Carolina to Texas, and along the coast of eastern Mexico and on Caribbean islands from Barbados to Cuba and the Bahamas (Haig and Elliott-Smith 2004). Piping plover subspecies are phenotypically indistinguishable, and most studies in the nonbreeding range report results without regard to breeding origin. Although a recent analysis shows strong patterns in the wintering distribution of piping plovers from different breeding populations,partitioning is not rnmplete and major information gaps persist. Therefore, information summarized here pertains to the species as a whole (i.e., all three breeding populations),except where a particular breeding population is specified. Critical habitat The Service has designated critical habitat for the piping plover on three occasions. Two of these designations protected different piping plover breeding populations. Critical habitat for the Great Lakes breeding population was designated May 7, 2001 (66 Federal Register[FR]22938, Service 2001 a),and critical habitat for the northern Great Plains breeding population was designated 4 CAC January 10,2013 VII-5 Staff Reports 5 of 64 September 11,2002(67 FR 57637,Service 2002). The Service designated critical habitat for wintering piping plovers on July 10,2001 (66 FR 36038;Service 2001a). Wintering piping plovers may include individuals from the Great Lakes and northern Great Plains breeding populations as well as birds that nest along the Atlantic Coast. The three separate designations of piping plover critical habitat demonstrate diversity of constituent elements between the two breeding populations as well as diversity of constituent elements between breeding and wintering populations. Designated wintering piping plover critical habitat originally included 142 areas (the rule states 137 units; this is an error)encompassing approximately 1,793 miles of mapped shoreline and 165,211 acres of mapped areas along the coasts of North Carolina, South Carolina, Georgia, Florida, Alabama, Mississippi, Louisiana, and Texas. Since the designation of wintering critical habitat, 19 units (TX-3, 4, 7-10, 14-19, 22, 23, 27, 28, and 31-33) in Texas have been vacated and remanded back to the Service for reconsideration by Court order(Texas General Land Once vs. U.S. Department of Interior[Case No. V-06-CV-00032]). On May 19, 2009, the Service published a final rule designating 18 revised critical habitat units in Texas, totaling approximately 139,029 acres (74 FR 23476). The Courts vacated and remanded back to the Service for reconsideration, four units in North Carolina(Cape Hatteras Access Preservation Alliance vs. U.S. Department of Interior[344 F. Supp. 2d 108 D.D.C. 2004]). The four critical habitat units vacated were NC-1, 2, 4, and 5, and all occurred within Cape Hatteras National Seashore. A revised designation for these four units was published on October 21, 2008 (73 FR 62816). On February 6, 2009, Cape Hatteras Access Preservation Alliance and Dare and Hyde Counties,North Carolina, filed a legal challenge to the revised designation. A final decision has not been made on the North Carolina challenge to date. The primary constituent elements (PCEs)for piping plover wintering habitat are those biological and physical features that are essential to the conservation of the species. The PCEs are those habitat components that support foraging,roosting,and sheltering,and the physical features necessary for maintaining the natural processes that support these habitat components. PCEs typically include those coastal areas that support intertidal beaches and flats, and associated dune systems and flats above annual high tide(Service 2001b). PCEs of wintering piping plover critical habitat include sand or mud flats or both with no or sparse emergent vegetation. Adjacent unvegetated or sparsely vegetated sand, mud,or algal flats above high tide are also important,especially for roosting piping plovers(Service 2001 b). Important components of the beach/dune ecosystem include surf-cast algae, sparsely vegetated back beach and salterns,spits,and washover areas. Washover areas are broad,unvegetated zones,with little or no topographic relief,that are formed and maintained by the action of hurricanes,storm surge, or other extreme wave action. The units designated as critical habitat are those areas that have consistent use by piping plovers and that best meet the biological needs of the species. The amount of wintering habitat included in the designation appears sufficient to support future recovered populations,and the existence of this habitat is essential to the conservation of the species. Additional information on each specific unit included in the designation can be found at 66 FR 36038 (Service 2001b). Feeding areas Plovers forage on moist substrate features such as intertidal portions of ocean beaches, washover areas, mudflats, sand flats, algal flats, shoals, wrack lines, sparse vegetation, and shorelines of 5 CAC January 10,2013 VII-5 Staff Reports 6 of 64 coastal ponds, lagoons, and ephemeral pools,and adjacent to salt marshes (Gibbs 1986; Zivojnovich 1987; Nicholls 1989; Coutu et al. 1990; Nicholls and Baldassarre 1990a; Nicholls and Baldassarre 1990b; Hoopes et al. 1992; Loegering 1992; Goldin 1993a; Elias-Gerken 1994; Wilkinson and Spinks 1994; Zonick 1997; Service 2001b). Studies have shown the relative importance of various feeding habitat types may vary by site (Gibbs 1986; Coutu et al. 1990; McConnaughey et al. 1990; Loegering 1992; Goldin 1993a; Hoopes 1993). Cohen et al. (2008) documented more abundant prey items and biomass on sound island and sound beaches than the ocean beach. Ecological Associates Incorporated [EAI] (2009) observed during piping plover surveys conducted at St Lucie Inlet, Martin County, Florida, intertidal mudflats and/or shallow subtidal grassflats appeared to have greater value as foraging habitat than the unvegetated intertidal areas of a flood shoal. Foraging/food Behavioral observations of piping plovers on the wintering grounds suggest they spend the majority of their time foraging(Nicholls and Baldassarre 1990a; Drake 1999a, 1999b). Feeding activities may occur during all hours of the day and night(Staine and Burger 1994; Zonick 1997), and at all stages in the tidal cycle (Goldin 1993a; Hoopes 1993). Wintering plovers primarily feed on invertebrates such as polychaete marine worms, various crustaceans, fly larvae, beetles, and occasionally bivalve mollusks (Bent 1929; Cairns 1977; Nicholls 1989; Zonick and Ryan 1996) found on top of the soil or just beneath the surface. Habitat Wintering piping plovers prefer coastal habitats that include sand spits, islets (small islands), tidal flats, shoals (usually flood tidal deltas), and sandbars that are often associated with inlets (Harrington 2008). Sandy mud flats, ephemeral pools, and overwash areas are also considered primary foraging habitats. These substrate types have a richer infauna than the foreshore of high energy beaches and often attract large numbers of shorebirds(Cohen et al. 2008). Wintering plovers are dependent on a mosaic of habitat patches and move among these patches depending on local weather and tidal conditions (Nicholls and Baldassarre 1990a). Recent study results in North Carolina, South Carolina, and Florida complement information from earlier investigations in Texas and Alabama(summarized in the 1996 Atlantic Coast and 2003 Great Lakes Recovery Plans) regarding habitat use patterns of piping plovers in their coastal migration and wintering range. As documented in Gulf Coast studies, nonbreeding piping plovers in North Carolina primarily used sound (bay or bayshore) beaches and sound islands for foraging and ocean beaches for roosting, preening, and being alert(Cohen et al. 2008). The probability of piping plovers being present on the sound islands increased with increasing exposure of the intertidal area (Cohen et al. 2008). Maddock et al. (2009) observed shifts to roosting habitats and behaviors during high-tide periods in South Carolina. Seven years of surveys, two to three times per month, along 8 miles of Gulf of Mexico (ocean- facing) beach in Gulf County, Florida, cumulatively documented nearly the entire area used at various times by roosting or foraging piping plovers. Birds were reported using the midbeach to the intertidal zone. Numbers ranged from 0 to 39 birds on any given survey day (Eells unpublished data). 6 CAC January 10,2013 VII-5 Staff Reports 7 of 64 As observed in Texas studies, Lott et al. (2009) identified bay beaches (bay shorelines as opposed to ocean-facing beaches) as the most common landform used by foraging piping plovers in southwest Florida. However in northwest Florida, Smith (2007) reported landform use by foraging piping plovers about equally divided between Gulf of Mexico (ocean-facing) and bay beaches. Exposed intertidal areas were the dominant foraging substrate in South Carolina (accounting for 94 percent of observed foraging piping plovers; Maddock et al. 2009) and in northwest Florida(96 percent of foraging observations; Smith 2007). In southwest Florida, Lott et al. (2009)found approximately 75 percent of foraging piping plovers on intertidal substrates. Atlantic Coast and Florida studies highlighted the importance of inlets for nonbreeding piping plovers. Almost 90 percent of roosting piping plovers at ten coastal sites in southwest Florida were on inlet shorelines (Lott et al. 2009). Piping plovers were among 7 shorebird species found more often than expected (p=0.0004; Wilcoxon Test Scores) at inlet locations versus noninlet locations in an evaluation of 361 International Shorebird Survey sites from North Carolina to Florida(Harrington 2008). Recent geographic analysis of piping plover distribution on the upper Texas coast noted major concentration areas at the mouths of rivets,washover passes (low, sparsely vegetated barrier island habitats created and maintained by temporary, storm-driven water channels),and major bay systems (Arvin 2008). Earlier studies in Texas have drawn attention to washover passes, which are commonly used by piping plovers during periods of high bayshore tides and during the spring migration period (Zonick 1997, 2000). Elliott-Smith et al. (2009) reported piping plover concentrations on exposed seagrass beds and oyster reefs during seasonal low water periods in 2006. The effects of dredge material deposition merit further study. Drake et al. (2001)concluded conversion of southern Texas mainland bayshore tidal flats to dredged material impoundments results in a net loss of habitat for wintering piping plovers because impoundments eventually convert to upland habitat not utilized by piping plovers. Zonick et al. (1998) reported dredged material placement areas along the intracoastal waterway in Texas were rarely used by piping plovers, and noted concern that dredge islands block wind-driven water flows which are critical to maintaining important shorebird habitats. By contrast, most of the sound islands used by foraging piping plovers at Oregon Inlet were created by the Corps through deposition of dredged material in the subtidal bay bottom, with the most recent deposition ranging from 28 to less than 10 years prior to the study (Cohen et al. 2008). Mean home range size (95 percent of locations) for 49 radio tagged piping plovers in southern Texas in 1997 through 1998 was 3,113 acres, mean core area(50 percent of locations) was 717 acres,and the mean linear distance moved between successive locations (1.97 +0.04 days apart) averaged across seasons, was 2.1 miles (Drake 1999a; Drake et al. 2001). Seven radio- tagged piping plovers used a 4,967-acre area(100 percent minimum convex polygon) at Oregon Inlet in 2005 and 2006, and piping plover activity was concentrated in 12 areas totaling 544 acres (Cohen et al. 2008). Noel and Chandler(2008) observed high fidelity of banded piping plovers along a 0.62 and 2.8 mile section of beach on Little St. Simons Island, Georgia. 7 CAC January 10,2013 VII-5 Staff Reports 8 of 64 Migration Plovers depart their breeding grounds for their wintering grounds between July and late August, but southward migration extends through November. Piping plovers use habitats in Florida primarily from July 15 through May 15. Both spring and fall migration routes of Atlantic Coast breeders are believed to occur primarily within a narrow zone along the Atlantic Coast (Service 1996). The pattern of both fall and spring counts at many Atlantic Coast sites demonstrates that many piping plovers make intermediate stopovers lasting from a few days up to 1 month during their migrations (Noel and Chandler 2005; Stucker and Cuthbert 2006). Some midcontinent breeders travel up or down the Atlantic Coast before or after their overland movements (Stucker and Cuthbert 2006). Use of inland stopovers during migration is also documented (Pompei and Cuthbert 2004). The source breeding population of a given wintering individual cannot be determined in the field unless it has been banded or otherwise marked. Information from observation of color-banded piping plovers indicates that the winter ranges of the breeding populations overlap to a significant degree. See the Status and Distribution section for additional information pertaining to population distribution on the wintering grounds. While piping plover migration patterns and needs remain poorly understood and occupancy of a particular habitat may involve shorter periods relative to wintering, information about the energetics of avian migration indicates that this might be a particularly critical time in the species' life cycle. Natural protection Cryptic coloration is a primary defense mechanism for piping plovers where nests, adults, and chicks all blend in with their typical beach surroundings. Piping plovers on wintering and migration grounds respond to intruders (e.g., pedestrian, avian, and mammalian) usually by squatting, running, and flushing(flying). • Roosting Several studies identified wrack (organic material including seaweed, seashells, driftwood, and other materials deposited on beaches by tidal action) as an important component of roosting habitat for nonbreeding piping plovers. Lott et al. (2009) found greater than 90 percent of roosting piping plovers in southwest Florida in old wrack with the remainder roosting on dry sand. In South Carolina, 18 and 45 percent of roosting piping plovers were in fresh and old wrack, respectively. The remainder of roosting birds used intertidal habitat (22 percent), backshore (defined as the zone of dry sand, shell, cobble and beach debris from the mean high water line up to the toe of the dune; 8 percent),washover(2 percent),and ephemeral pools(1 percent) (Maddock et al. 2009). Thirty percent of roosting piping plovers in northwest Florida were observed in wrack substrates, with 49 percent roosting on dry sand and 20 percent using intertidal habitat (Smith 2007). In Texas, seagrass debris (bayshore wrack) was an important feature of piping plover roosting sites (Drake 1999a). Mean abundance of two other plover species in California, including the listed western snowy plover, was positively correlated with an abundance of wrack during the nonbreeding season (Dugan et al. 2003). 8 CAC January 10,2013 VII-5 Staff Reports 9 of 64 Life history Piping plovers live an average of 5 years, although studies have documented birds as old as 11 (Wilcox 1959) and 15 years. Piping plover breeding activity begins in mid-March when birds begin returning to their nesting areas (Coutu et al. 1990; Cross 1990; Goldin et al. 1990; MacIvor 1990; Hake 1993). Plovers are known to begin breeding as early as 1 year of age(Maclvor 1990; Haig 1992); however, the percentage of birds that breed in their first adult year is unknown. Piping plovers generally fledge only a single brood per season, but may re-nest several times if previous nests are lost. The most consistent finding in the various population viability analyses conducted for piping plovers (Ryan et al. 1993; Melvin and Gibbs 1996; Plissner and Haig 2000; Wemmer et al. 2001; Larson et al. 2002; Amirault et al. 2005; Calvert et al. 2006; Brault 2007) indicates even small declines in adult and juvenile survival rates will cause increases in extinction risk. A banding study conducted between 1998 and 2004 in Atlantic Canada concluded lower return rates of juvenile(first year) birds to the breeding grounds than was documented for Massachusetts (Melvin and Gibbs 1994), Maryland (Loegering 1992), and Virginia(Cross 1996) breeding populations in the mid-1980s and very early 1990s. This is consistent with failure of the Atlantic Canada population to increase in abundance despite high productivity (relative to other breeding populations) and extremely low rates of dispersal to the U.S. over the last 15 plus years (Amirault et al. 2005). This suggests maximizing productivity does not ensure population increases. Efforts to partition survival within the annual cycle are beginning to receive more attention, but current information remains limited. Drake et al. (2001) observed no mortality among 49 radio- tagged piping plovers (total of 2,704 transmitter days) in Texas in 2007 and 2008. Cohen et al. (2008) documented no mortality of 7 radio-tagged wintering piping plovers at Oregon Inlet from December 2005 to March 2006. They speculate their high survival rate was attributed to plover food availability much of the day as well as the low occurrence of days below freezing and infrequent wet weather. Analysis of South Carolina resighting data for 87 banded piping plovers (78 percent Great Lakes breeders) in 2006 and 2007, and 2007 and 2008, found 100 percent survival from December to April (Cohen 2009). However, of those birds, one unique and one nonuniquely banded piping plover were seen in the first winter and resighted multiple times in the second fall at the same location, but not seen during the second winter. Whether these two birds died in the fall or shifted their wintering location is unknown (Maddock et al. 2009). Noel et al. (2007) inferred two winter(November to February) mortalities among 21 banded (but not radio-tagged) overwintering piping plovers in 2003 through 2004, and 9 mortalities among 19 overwintering birds during the winter of 2004 through 2005 at Little St.Simons Island,Georgia. Noel et al. (2001)inferred mortality it a uniquely banded piping plover with multiple November to February sightings on the survey site disappeared during that time and was never observed again in either its nonbreeding or breeding range. Note that most of these birds were from the Great Lakes breeding population,where detectability during the breeding season is very high. LeDee (2008) found higher apparent survival rates during breeding and southward migration than during winter and northward migration for 150 adult (i.e., after-hatch year) Great Lakes piping plovers. "Apparent survival"does not account for permanent emigration. If marked individuals leave a survey site, apparent survival rates will be lower than true survival. If a survey area is sufficiently large, such that emigration out of the site is unlikely, apparent survival will approach true survival. 9 CAC January 10,2013 VII-5 Staff Reports 10 of 64 Mark-recapture analysis of resightings of uniquely banded piping plovers from seven breeding areas by Roche et al. (2009) found apparent adult survival declined in four populations and did not increase over the life of the studies (data were analyzed for 3 to 11 years per breeding area between 1998 and 2008). Some evidence of correlation in year-to-year fluctuations in annual survival of Great Lakes and eastern Canada populations,both of which winter primarily along the southeastern U.S. Atlantic Coast, suggests shared over-wintering and/or migration habitats may influence annual variation in survival. Further concurrent mark-resighting analysis of color- banded individuals across piping plover breeding populations has the potential to shed light on threats that affect survival in the migration and wintering range. Population dynamics The 2006 International Piping Plover Breeding Census,the last comprehensive survey throughout the breeding grounds,documented 3,497 breeding pairs with a total of 8,065 birds throughout Canada and the U.S, and a total of 454 in Florida(Elliott-Smith et al. 2009). The surveys covered approximately 760.5 miles and included 186 sites (Elliott-Smith et al 2009). As the Atlantic Coast is not included in the action area, the breakdown for the Gulf Coast of Florida is: 321 piping plovers at 117 sites covering approximately 522 miles of suitable habitat (Elliott-Smith et al 2009). Numbers for Florida can be further broken down into 3 regions along the Gulf Coast. The northwest Florida census area in the panhandle extends from the Alabama line to Jefferson County, the north Florida census area from Taylor County south to Manatee County, and southwest Florida from Sarasota County south to Key West National Wildlife Refuge. Northwest Florida numbers for the 2006 International Piping Plover Census were 111, with an increased survey effort from previous years. This represents an increase from the 53 piping plovers sighted in the 2001 effort. North Florida reported 96 birds and estimated an additional 40 from missing data sheets. There were 74 piping plovers located in southwest Florida as compared to 50 in the 2001 effort (Elliott-Smith et al 2009). The mainland portion of Monroe County is, technically, on the Gulf Coast of Florida; however, the predominant habitat is mangrove shoreline and no piping plovers were sighted at the survey location on Pavilion Key. Atlantic Coast population The Atlantic Coast piping plover breeds on coastal beaches from Newfoundland and southeastern Quebec to North Carolina. Historical population trends for the Atlantic Coast piping plover have been reconstructed from scattered, largely qualitative records. Nineteenth- century naturalists, such as Audubon and Wilson, described the piping plover as a common summer resident on Atlantic Coast beaches (Haig and Oring 1987). However, by the beginning of the twentieth century, egg collecting and uncontrolled hunting, primarily for the millinery trade, had greatly reduced the population, and in some areas along the Atlantic Coast, the piping plover was close to extirpation. Following passage of the Migratory Bird Treaty Act (MBTA) in 1918, and changes in the fashion industry that no longer exploited wild birds for feathers, piping plover numbers recovered to some extent (Haig and Oring 1985). Available data suggest the most recent population decline began in the late 1940s or early 1950s (Haig and Oring 1985). Reports of local or statewide declines between 1950 and 1985 are numerous, and many are summarized by Cairns and McLaren (1980). and Haig and Oring(1985). 10 CAC January 10,2013 VII-5 Staff Reports 11 of 64 While Wilcox (1939)estimated more than 500 pairs of piping plovers on Long Island, New York, the 1989 population estimate was 191 pairs (Service 1996). There was little focus on gathering quantitative data on piping plovers in Massachusetts through the late 1960s because the species was commonly observed and presumed to be secure. However, numbers of piping plover breeding pairs declined 50 to 100 percent at 7 Massachusetts sites between the early 1970s and 1984 (Griffin and Melvin 1984). Piping plover surveys in the early years of the recovery effort found counts of these cryptically colored birds sometimes increased with increased census effort, suggesting some historic counts of piping plovers by one or more observers may have underestimated the piping plover population. Thus, the magnitude of the species decline may have been more severe than available numbers imply. The New England recovery unit population has exceeded (or been within 3 pairs of) its 625-pair abundance goal since 1998, attaining a postlisting high of 711 pairs in 2008. The New York- New Jersey recovery unit reached 586 pairs in 2007, surpassing its 575-pair goal for the first time; however, in 2008, abundance dipped to 554 pairs. The Southern recovery unit, which attained 333 and 331 pairs in 2007 and 2008, respectively, has not yet reached its 400-pair goal. The Eastern Canada recovery unit has experienced the lowest population growth (9 percent net increase between 1989 and 2008), despite higher overall productivity than in the U.S. The highest postlisting abundance estimate was 274 pairs in 2002, with a 2008 estimate of 253 pairs, placing this recovery unit furthest from its goal (400 pairs). Great Lakes population The Great Lakes plovers once nested on Great Lakes beaches in Illinois, Indiana,Michigan, Minnesota,New York, Ohio, Pennsylvania, Wisconsin, and Ontario. Great Lakes piping plovers nest on wide,flat,open, sandy or cobble shoreline with very little grass or other vegetation. Reproduction is adversely affected by human disturbance of nesting areas and predation by foxes, gulls, crows and other avian species. Shoreline development,such as the construction of marinas, breakwaters, and other navigation structures, has adversely affected nesting and brood rearing. The Recovery Plan (Service 2003a) set a population goal of at least 150 pairs (300 individuals), for at least 5 consecutive years, with at least 100 breeding pairs (200 individuals) in Michigan and 50 breeding pairs (100 individuals) distributed among sites in other Great Lakes states. In 2008, the current Great Lakes piping plover population was estimated at 63 breeding pairs (126 individuals). Of these, 53 pairs were found nesting in Michigan, while 10 were found outside the state, including 6 pairs in Wisconsin and 4 in Ontario. The 53 nesting pairs in Michigan represent approximately 50 percent of the recovery criterion. The 10 breeding pairs outside Michigan in the Great Lakes basin represents 20 percent of the goal, albeit the number of breeding pairs outside Michigan has continued to increase over the past 5 years. The single breeding pair discovered in 2007 in the Great Lakes region of Canada represented the first confirmed piping plover nest there in over 30 years, and in 2008 the number of nesting pairs further increased to four. Northern Great Plains population The Northern Great Plains plover breeds from Alberta to Manitoba, Canada, and south to Nebraska; although some nesting has recently occurred in Oklahoma. Currently, the most 11 CAC January 10,2013 VII-5 Staff Reports 12 of 64 westerly breeding piping plovers in the U.S. occur in Montana and Colorado. The decline of piping plovers on rivers in the Northern Great Plains has been largely attributed to the loss of sandbar island habitat and forage base due to dam construction and operation. Nesting occurs on sand flats or bare shorelines of rivers and lakes, including sandbar islands in the upper Missouri River system, and patches of sand, gravel,or pebbly-mud on the alkali lakes of the northern Great Plains. Plovers do nest on shorelines of reservoirs created by the dams,but reproductive success is often low and reservoir habitat is not available in many years due to high water levels or vegetation. Dams operated with steady constant flows allow vegetation to grow on potential nesting islands, making these sites unsuitable for nesting. Population declines in alkali wetlands are attributed to wetland drainage, contaminants, and predation. The International Piping Plover Census, conducted every 5 years, also estimates the number of piping plover pairs in the Northern Great Plains. None of the International Piping Plover Census estimates suggest the Northern Great Plains population has yet satisfied the recovery criterion of 2,300 pairs (Table 1). The International Piping Plover Census results in prairie Canada reported 1,703 adult birds in 2006, well short of the goal of 2,500 adult piping plover as stated in the Service's Recovery Plan (Service 1988). Status and distribution Nonbreeding(migrating and wintering) Piping plovers spend up to 10 months of their life cycle on their migration and at wintering grounds, generally July 15 through as late as May 15. Piping plover migration routes and habitats overlap breeding and wintering habitats, and, unless banded, migrants passing through a site usually are indistinguishable from breeding or wintering piping plovers. Migration stopovers by banded piping plovers from the Great Lakes have been documented in New Jersey, Maryland, Virginia, and North Carolina(Stucker and Cuthbert 2006). Migrating breeders from eastern Canada have been observed in Massachusetts, New Jersey, New York, and North Carolina (Amirault et al. 2005). As many as 85 staging piping plovers have been tallied at various sites in the Atlantic breeding range (Perkins 2008), but the composition (e.g., adults that nested nearby and their fledged young of the year versus migrants moving to or from sites farther north), stopover duration, and local movements are unknown. In general, distance between stopover locations and duration of stopovers throughout the coastal migration range remains poorly understood. Review of published records of piping plover sightings throughout North America by Pompei and Cuthbert(2004)found more than 3,400 fall and spring stopover records at 1,196 sites. Published reports indicated piping plovers do not concentrate in large numbers at inland sites and they seem to stop opportunistically. In most cases,reports of birds at inland sites were single individuals. Piping plovers migrate through and winter in coastal areas of the U.S. from North Carolina to Texas and in portions of Mexico and the Caribbean. Data based on four rangewide mid-winter (late January to early February) population surveys, conducted at 5-year intervals starting in 1991, show that total numbers have fluctuated over time, with some areas experiencing increases 12 CAC January 10,2013 VII-5 Staff Reports 13 of 64 and others decreases (Table 2). Regional and local fluctuations may reflect the quantity and quality of suitable foraging and roosting habitat, which vary over time in response to natural coastal formation processes as well as anthropogenic habitat changes (e.g., inlet relocation, dredging of shoals and spits). Fluctuations may also represent localized weather conditions (especially wind) during surveys, or unequal survey coverage. For example, airboats facilitated first-time surveys of several central Texas sites in 2006 (Elliott-Smith et al. 2009). Similarly, the increase in the 2006 numbers in the Bahamas is attributed to greatly increased census efforts; the extent of additional habitat not surveyed remains undetermined (Elliott-Smith et al. 2009). Changes in wintering numbers may also be influenced by growth or decline in the particular breeding populations that concentrate their wintering distribution in a given area. Opportunities to locate previously unidentified wintering sites are concentrated in the Caribbean and Mexico (Elliott-Smith et al. 2009). Further surveys and assessment of seasonally emergent habitats (e.g., seagrass beds, mudflats, oyster reefs) within bays lying between the mainland and barrier islands in Texas are also needed. Midwinter surveys may underestimate the abundance of nonbreeding piping plovers using a site or region during other months. In late September 2007, 104 piping plovers were counted at the south end of Ocracoke Island,North Carolina(National Park Service [NPS] 2007), where none were seen during the 2006 International Piping Plover Winter Census (Elliott-Smith et al. 2009). Noel et al. (2007) observed up to 100 piping plovers during peak migration at Little St. Simons Island,Georgia,where approximately 40 piping plovers wintered in 2003 to 2005. Differences among fall, winter, and spring counts in South Carolina were less pronounced, but inter-year fluctuations (e.g., 108 piping plovers in spring 2007 versus 174 piping plovers in spring 2008) at 28 sites were striking (Maddock et al. 2009). Even as far south as the Florida Panhandle, monthly counts at Phipps Preserve in Franklin County ranged from a midwinter low of four piping plovers in December 2006, to peak counts of 47 in October 2006 and March 2007 (Smith 2007). Pinkston (2004) observed much heavier use of Texas Gulf Coast (ocean-facing) beaches between early September and mid-October (approximately 16 birds per mile) than during December to March (approximately 2 birds per mile). Local movements of non-breeding piping plovers may also affect abundance estimates. At Deveaux Bank,one of South Carolina's most important piping plover sites,5 counts at approximately 10-day intervals between August 27 and October 7, 2006,oscillated from 28 to 14 to 29 to 18 to 26 (Maddock et al. 2009). Noel and Chandler(2008)detected banded Great Lakes piping plovers known to be wintering on their Georgia study site in 73.8±8.1 percent of surveys over 3 years. Abundance estimates for non-breeding piping plovers may also be affected by the number of surveyor visits to the site. Preliminary analysis of detection rates by Maddock et al. (2009) found 87 percent detection during the midwinter period on core sites surveyed 3 times a month during fall and spring and one time per month during winter, compared with 42 percent detection on sites surveyed 3 times per year(Cohen 2009). Gratto-Trevor et al. (2009) found strong patterns (but no exclusive partitioning) in winter distribution of uniquely banded piping plovers from four breeding populations (Figure 2). All eastern Canada and 94 percent of Great Lakes birds wintered from North Carolina to southwest 13 CAC January 10,2013 VII-5 Staff Reports 14 of 64 Florida. However, eastern Canada birds were more heavily concentrated in North Carolina, and a larger proportion of Great Lakes piping plovers were found in South Carolina and Georgia. Northern Great Plains populations were primarily seen farther west and south, especially on the Texas Gulf Coast. Although the great majority of Prairie Canada individuals were observed in Texas, particularly southern Texas, individuals from the U.S. Great Plains were more widely distributed on the Gulf Coast from Florida to Texas. The findings of Gratto-Trevor et al. (2009) provide evidence of differences in the wintering distribution of piping plovers from these four breeding areas. However, the distribution of birds by breeding origin during migration remains largely unknown. Other major information gaps include the wintering locations of the U.S. Atlantic Coast breeding population(banding of U.S. Atlantic Coast piping plovers has been extremely limited) and the breeding origin of piping plovers wintering on Caribbean islands and in much of Mexico. Banded piping plovers from the Great Lakes,Northern Great Plains, and eastern Canada breeding populations showed similar patterns of seasonal abundance at Little St. Simons Island, Georgia(Noel et al. 2007). However, the number of banded plovers originating from the latter two populations was relatively small at this study area. This species exhibits a high degree of intra- and interannual wintering site fidelity (Nicholls and Baldassarre 1990a; Drake et al. 2001; Noel and Chandler 2005; Stucker and Cuthbert 2006). Gratto-Trevor et al. (2009) reported that 6 of 259 banded piping plovers observed more than once per winter moved across boundaries of the seven U.S. regions. Of 216 birds observed in different years, only 8 changed regions between years, and several of these shifts were associated with late summer or early spring migration periods (Gratto-Trevor et al. 2009). Total number of individuals observed on the wintering grounds was 46 for Eastern Canada, 150 for the U.S. Great Lakes, 169 for the U.S. Great Plains, and 356 for Prairie Canada. Local movements are more common. In South Carolina, Maddock et al. (2009) documented many cross-inlet movements by wintering banded piping plovers as well as occasional movements of up to 11.2 miles by approximately 10 percent of the banded population. Larger movements within South Carolina were seen during fall and spring migration. Similarly,eight banded piping plovers that were observed in two locations during 2006 and 2007 surveys in Louisiana and Texas were all in close proximity to their original location (Maddock 2008). In 2001, 2,389 piping plovers were located during a winter census, accounting for only 40 percent of the known breeding birds recorded during a breeding census (Ferland and Haig 2002). About 89 percent of birds that are known to winter in the U.S. do so along the Gulf Coast (Texas to Florida),while 8 percent winter along the Atlantic Coast (North Carolina to Florida). The status of piping plovers on winter and migration grounds is difficult to assess, but threats to piping plover habitat used during winter and migration identified by the Service during its designation of critical habitat continue to affect the species. Unregulated motorized and pedestrian recreational use, inlet and shoreline stabilization projects,beach maintenance and nourishment, and pollution affect most winter and migration areas. Conservation efforts at some locations have likely resulted in the enhancement of wintering habitat. 14 CAC January 10,2013 VII-5 Staff Reports 15 of 64 The 2004 and 2005 hurricane seasons affected a substantial amount of habitat along the Gulf Coast. Habitats such as those along Gulf Islands National Seashore have benefited from increased washover events which created optimal habitat conditions for piping plovers. Conversely, hard shoreline structures are put into place following storms throughout the species range to prevent such shoreline migration (see Factors Affecting the Species Habitat within the Action Area). Four hurricanes between 2002 and 2005 are often cited in reference to rapid erosion of the Chandeleur Islands, a chain of low-lying islands in Louisiana where the 1991 International Piping Plover Census tallied more than 350 piping plovers. Comparison of imagery taken 3 years before and several days after Hurricane Katrina found that the Chandeleur Islands lost 82 percent of their surface area(Sallenger et al. in review), and a review of aerial photography prior to the 2006 Census suggested little piping plover habitat remained (Elliott- Smith et al. 2009). However, Sallenger et al. (in review) noted habitat changes in the Chandeleurs stem not only from the effects of these storms,but rather from the combined effects of the storms, long-term (greater than 1,000 years) diminishing sand supply, and sea level rise relative to the land. The Service is aware of the following site specific conditions that affect the status of several habitats piping plover use while wintering and migrating, including critical habitat units. In Texas, one critical habitat unit was afforded greater protection due to the acquisition of adjacent upland properties by the local Audubon chapter. In another unit in Texas, vehicles were removed from a portion of the beach, decreasing the likelihood of automobile disturbance to plovers. Exotic plant removal is occurring in another critical habitat unit in South Florida. The Service and other government agencies remain in a contractual agreement with the U.S. Department of Agriculture for predator control within limited coastal areas in the Florida panhandle, including portions of some critical habitat units. Continued removal of potential terrestrial predators is likely to enhance survivorship of wintering and migrating piping plovers. In North Carolina, one critical habitat unit was afforded greater protection when the local Audubon chapter agreed to manage the area specifically for piping plovers and other shorebirds following the relocation of a nearby inlet channel. Recovery criteria Northern Great Plains Population (Service 1988, 1994) 1.

Threats to Piping Plovers In the following sections, threats to piping plovers in their migration and wintering range is provided. This information has been updated since the 1985 listing rule, the 1991 status review, and the three breeding population recovery plans, Previously identified and new threats are discussed. With minor exceptions, this analysis is focused on threats to piping plovers within the continental U.S. portion of their migration and wintering range. Threats in the Caribbean and Mexico remain largely unknown. Present or threatened destruction, modification, or curtailment of its habitat or range The 1985 final rule stated the number of piping plovers on the Gulf of Mexico coastal wintering grounds might be declining as indicated by preliminary analysis of the Christmas Bird Count data. Independent counts of piping plovers on the Alabama coast indicated a decline in numbers 16 CAC January 10,2013 VII-5 Staff Reports 17 of 64 between the 1950s and early 1980s. At the time of listing, the Texas Parks and Wildlife Department stated that 30 percent of wintering habitat in Texas had been lost over the previous 20 years. The final rule also stated in addition to extensive breeding area problems, the loss and modification of wintering habitat was a significant threat to the piping plover. The three recovery plans stated shoreline development throughout the wintering range poses a threat to all populations of piping plovers. The plans further stated beach maintenance and nourishment, inlet dredging, and artificial structures such as jetties and groins, could eliminate wintering areas and alter sedimentation patterns leading to the loss of nearby habitat. Priority 1 actions in the 1996 Atlantic Coast and 2003 Great Lakes Recovery Plans identify tasks to protect natural processes that maintain coastal ecosystems and quality wintering piping plover habitat, and to protect wintering habitat from shoreline stabilization and navigation projects. The 1988 Northern Great Plains Plan states as winter habitat is identified, current and potential threats to each site should be determined. Important components of ecologically sound barrier beach management include perpetuation of natural dynamic coastal formation processes. Structural development along the shoreline or manipulation of natural inlets upsets the dynamic processes and results in habitat loss or degradation (Melvin et al. 1991). Throughout the range of migrating and wintering piping plovers, inlet and shoreline stabilization, inlet dredging,beach maintenance and nourishment activities, and seawall installations continue to constrain natural coastal processes. Dredging of inlets can affect spit formation adjacent to inlets and directly remove or affect ebb and flood tidal shoal formation. Jetties,which stabilize an island,cause island widening and subsequent growth of vegetation on inlet shores. Seawalls restrict natural island movement and exacerbate erosion. As discussed in more detail below, all these efforts result in loss of piping plover habitat. Construction of these projects during months when piping plovers are present also causes disturbance that disrupts the birds' foraging efficiency and hinders their ability to build fat reserves over the winter and in preparation for migration, as well as their recuperation from migratory flights. Additional investigation is needed to determine the extent to which these factors cumulatively affect piping plover survival and how they may impede conservation efforts for the species. Any assessment of threats to piping plovers from loss and degradation of habitat must recognize that up to 24 shorebird species migrate or winter along the Atlantic Coast and almost 40 species of shorebirds are present during migration and wintering periods in the Gulf of Mexico region (Helmers 1992). Continual degradation and loss of habitats used by wintering and migrating shorebirds may cause an increase in intra-specifir: and inter-specific competition for remaining food supplies and roosting habitats. For example, in Florida approximately 825 miles of coastline and parallel bayside flats (unspecified amount) were present prior to the advent of high human densities and beach stabilization projects. We estimate only about 35 percent of the Florida coastline continues to support natural coastal formation processes, thereby concentrating foraging and roosting opportunities for all shorebird species and forcing some individuals into suboptimal habitats. Thus, intra- and interspecific competition most likely exacerbates threats from habitat loss and degradation. l7 CAC January 10,2013 VII-5 Staff Reports 18 of 64 Exotic/invasive vegetation A recently identified threat to piping plover habitat,not described in the listing rule or recovery plans, is the spread of coastal invasive plants into suitable piping plover habitat. Like most invasive species,coastal exotic plants reproduce and spread quickly and exhibit dense growth habits,often outcompeting native plant species. If left uncontrolled,invasive plants cause a habitat shift from open or sparsely vegetated sand to dense vegetation,resulting in the loss or degradation of piping plover roosting habitat,which is especially important during high tides and migration periods. Beach vitex (Vitex rotundifolia) is a woody vine introduced into the southeastern U.S. as a dune stabilization and ornamental.plant (Westbrooks and Madsen 2006). It currently occupies a very small percentage of its potential range in the U.S.; however, it is expected to grow well in coastal communities throughout the southeastern U.S. from Virginia to Florida, and west to Texas (Westbrooks and Madsen 2006). In 2003, the plant was documented in New Hanover, Pender, and Onslow counties in North Carolina, and at 125 sites in Horry, Georgetown, and Charleston counties in South Carolina. One Chesapeake Bay site in Virginia was eradicated, and another site on Jekyll Island,Georgia, is about 95 percent controlled (Suiter 2009). Beach vitex has been documented from two locations in northwest Florida, but one site disappeared after erosional storm events. The landowner of the other site has indicated an intention to eradicate the plant, but follow through is unknown (Farley 2009). Task forces formed in North and South Carolina in 2004 and 2005 have made great strides to remove this plant from their coasts. To date, about 200 sites in North Carolina have been treated, with 200 additional sites in need of treatment. Similar efforts are underway in South Carolina. Unquantified amounts of crowfootgrass (Dactylocteniumm aegyptiunn) grow invasively along portions of the Florida coastline. It forms thick bunches or mats that may change the vegetative structure of coastal plant communities and alter shorebird habitat. The Australian pine (Casuarina equisetifolia) changes the vegetative structure of the coastal community in south Florida and islands within the Bahamas. Shorebirds prefer foraging in open areas where they are able to see potential predators, and tall trees provide good perches for avian predators. Australian pines potentially affect shorebirds, including the piping plover, by reducing attractiveness of foraging habitat and/or increasing avian predation. The propensity of these exotic species to spread, and their tenacity once established, make them a persistent threat,partially countered by increasing landowner awareness and willingness to undertake eradication activities. Groins Groins (structures made of concrete, rip rap, wood, or metal built perpendicular to the beach in order to trap sand) are typically found on developed beaches with severe erosion. Although groins can be individual structures, they are often clustered along the shoreline. Groins act as barriers to longshore sand transport and cause downdrift erosion, which prevents piping plover habitat creation by limiting sediment deposition and accretion (Hayes and Michel 2008). These structures are found throughout the southeastern Atlantic Coast, and, although most were in place prior to the piping plover's 1986 Act listing, installation of new groins continues to occur. 18 CAC January 10,2013 VII-5 Staff Reports 19 of 64 Inlet stabilization/relocation Many navigable mainland or barrier island tidal inlets along the Atlantic and Gulf of Mexico coasts are stabilized with jetties, groins, seawalls, and/or adjacent industrial or residential development. Jetties are structures built perpendicular to the shoreline that extend through the entire nearshore zone and past the breaker zone(Hayes and Michel 2008) to prevent or decrease sand deposition in the channel. Inlet stabilization with rock jetties and associated channel dredging for navigation alter the dynamics of longshore sediment transport and affect the location and movement rate of barrier islands (Camfield and Holmes 1995), typically causing downdrift erosion. Sediment is then dredged and added back to islands which are subsequently widened. Once the island becomes stabilized, vegetation encroaches on the bayside habitat, thereby diminishing and eventually destroying its value to piping plovers. Accelerated erosion may compound future habitat loss, depending on the degree of sea level rise. Unstabilized inlets naturally migrate, reforming important habitat components, whereas jetties often trap sand and cause significant erosion of the downdrift shoreline. These combined actions affect the availability of piping plover habitat (Cohen et al. 2008). Using Google Earth© (accessed April 2009), Service biologists visually estimated the number of navigable mainland or barrier island tidal inlets throughout the wintering range of the piping plover in the conterminous U.S. that have some form of hardened structure(Table 3). This includes seawalls or adjacent development,which lock the inlets in place. Tidal inlet relocation can cause loss and/or degradation of piping plover habitat, although less permanent than construction of hard structures where effects can persist for years. For example, a project on Kiawah Island, South Carolina, degraded one of the most important piping plover habitats in the State by reducing the size and physical characteristics of an active foraging site, changing the composition of the benthic community, decreasing the tidal lag in an adjacent tidal lagoon,and decreasing the exposure time of the associated sand flats(Service and Town of Kiawah Island unpublished data). In 2006,preproject piping plover numbers in the project area recorded during four surveys conducted at low tide averaged 13.5 piping plovers. This contrasts with a postproject average of 7.1 plovers during eight surveys (four in 2007 and four in 2008)conducted during the same months (Service and Town of Kiawah Island unpublished data). Service biologists are aware of at least seven inlet relocation projects(two in North Carolina,three in South Carolina, two in Florida),but this number likely under represents the extent of this activity. Sand mining/dredging Sand mining, the practice of dredging sand from sand bars, shoals, and inlets in the nearshore zone, is a less expensive source of sand than obtaining sand from offshore shoals for beach nourishment. Sand bars and shoals are sand sources that move onshore over time and act as natural breakwaters. Inlet dredging reduces the formation of exposed ebb and flood tidal shoals considered to be primary or optimal piping plover roosting and foraging habitat. Removing these sand sources can alter depth contours and change wave refraction as well as cause localized erosion (Hayes and Michel 2008). Exposed shoals and sandbars are also valuable to piping plovers, as they tend to receive less human recreational use (because they are only accessible by boat) and therefore provide relatively less disturbed habitats for birds. An accurate estimate of the amount of sand mining that occurs across the piping plover wintering range, or the number of 19 CAC January 10,2013 VII-5 Staff Reports 20 of 64 inlet dredging projects that occur is not available. This number is likely greater than the number of total jettied inlets shown in Table 3, since most jettied inlets need maintenance dredging,but non-hardened inlets are often dredged as well. Sand placement projects In the wake of episodic storm events, managers of lands under public, private,and county ownership often protect coastal structures using emergency storm berms which are frequently followed by beach nourishment or renourishment activities (nourishment projects are considered "soft" stabilization versus"hard" stabilization such as seawalls). Berm placement and beach nourishment projects deposit substantial amounts of sand along Gulf of Mexico and Atlantic beaches to protect local property in anticipation of preventing erosion and what otherwise will be considered natural processes of overwash and island migration (Schmitt and Haines 2003). Past and ongoing stabilization projects fundamentally alter the natural dynamic coastal processes that create and maintain beach strand and bayside habitats, including those habitat components that piping plovers rely upon. Although the effects may vary depending on a range of factors, stabilization projects may directly degrade or destroy piping plover roosting and foraging habitat in several ways. Front beach habitat may be used to construct an artificial berm that is densely planted in grass, which can directly reduce the availability of roosting habitat. Over time, if the beach narrows due to erosion, additional roosting habitat between the berm and the water can be lost. Berms can also prevent or reduce the natural overwash that creates roosting habitats by converting vegetated areas to open sand areas. The vegetation growth caused by impeding natural overwash can also reduce the maintenance and creation of bayside intertidal feeding habitats. In addition, stabilization projects may indirectly encourage further development of coastal areas and increase the threat of disturbance. Lott et al. (in review) documented an increasing trend in sand placement events in Florida (Figure 3). Approximately 358 miles of 825 miles (43 percent) of Florida's sandy beach coastline were nourished from 1959 to 2006 (Table 4), with some areas being nourished multiple times. In northwest Florida,the Service consulted on first time sand placement projects along 46 miles of shoreline in 2007 to 2008, much of which occurred on public lands (Gulf Islands National Seashore([Service 2007a]), portions of St.Joseph State Park([Service 2007b]), and Eglin Air Force Base([Service 2008a]). At least 668 of 2,340 coastal shoreline miles (29 percent of beaches throughout the piping plover winter and migration range in the U.S.) are bermed, nourished, or renourished, generally for recreational purposes and to protect commercial and private infrastructure. However, only approximately 54 miles(2.31 percent)of these effects have occurred within critical habitat. In Louisiana, sand placement projects are deemed environmental restoration projects by the Service because without the sediment many areas would erode below sea level. Seawalls and revetments Seawalls and revetments are vertical hard structures built parallel to the beach in front of buildings, roads, and other facilities to protect them from erosion. However, these structures often accelerate erosion by causing scouring in front of and downdrift from the structure (Hayes and Michel 2008) which can eliminate intertidal foraging habitat and adjacent roosting habitat. 20 CAC January 10,2013 VII-5 Staff Reports 21 of 64 Physical characteristics that determine microhabitats and biological communities can be altered after installation of a seawall or revetment, thereby depleting or changing composition of benthic communities that serve as the prey base for piping plovers. At four California study sites, each comprised of an unarmored segment and a segment seaward of a seawall,Dugan and Hubbard (2006) found armored segments had narrower intertidal zones, smaller standing crops of macrophyte wrack, and lower shorebird abundance and species richness. Geotubes (long cylindrical bags made of high strength permeable fabric and filled with sand) are softer alternatives, but act as barriers by preventing overwash. Wrack removal and beach cleaning Wrack on beaches and baysides provides important foraging and roosting habitat for piping plovers (Drake 1999a; Smith 2007; Lott et al. 2009;Maddock et al. 2009) and many other shorebirds on their winter, breeding, and migration grounds. Because shorebird numbers are positively correlated with wrack cover and biomass of their invertebrate prey that feed on wrack (Tarr and Tarr 1987; Dugan et al. 2003; Hubbard and Dugan 2003), beach grooming will lower bird abundance (Defreo et al. 2009). There is increasing popularity in the Southeast, especially in Florida,for beach communities to carry out "beach cleaning" and"beach raking" actions. Beach cleaning occurs on private beaches, where piping plover use is not well documented, and on some municipal or county beaches that are used by piping plovers. Most wrack removal on State and Federal lands is limited to poststorm cleanup and does not occur regularly. Manmade beach cleaning and raking machines effectively remove seaweed, fish,glass,syringes, plastic, cans,cigarettes, shells, stone,wood,and virtually any unwanted debris (Barber Beach Cleaning Equipment 2011). These efforts remove accumulated wrack,topographic depressions, and sparse vegetation nodes used by roosting and foraging piping plovers. Removal of wrack also eliminates a beach's natural sand trapping abilities,further destabilizing the beach. In addition, sand adhering to seaweed and trapped in the cracks and crevices of wrack is removed from the beach. Although the amount of sand lost due to single sweeping actions may be small, it adds up considerably over a period of years (Nordstrom et al. 2006; Neal et al. 2007). Beach cleaning or grooming can result in abnormally broad unvegetated zones that are inhospitable to dune formation or plant colonization,thereby enhancing the likelihood of erosion (Defreo et al. 2009). Tilling beaches to reduce soil compaction, as sometimes required by the Service for sea turtle protection after beach nourishment activities,has similar effects. Recently, the Service improved set turtle protection provisions in Florida; These provisions now require tilling, when needed, to be conducted above the primary wrack line, not within it. Currently, the DEP's Beaches and Coastal Management Systems section has issued 117 permits for beach raking or cleaning to multiple entities. The Service estimates 240 of 825 miles(29 percent) of sandy beach shoreline in Florida are cleaned or raked on various (i.e., daily, weekly, monthly) schedules (Teich 2009). Service biologists estimate South Carolina mechanically cleans approximately 34 of its 187 shoreline miles (18 percent), and Texas mechanically cleans approximately 20 of its 367 shoreline miles (5.4 percent). The percentage of mechanical cleaning that occurs in piping plover critical habitat is unknown. 21 CAC January 10,2013 VII-5 Staff Reports 22 of 64 Overutilization for commercial, recreational,scientific or educational purposes The 1985 final listing rule found no evidence to suggest this factor is a threat to piping plovers while on migration or winter grounds. The various recovery plans state hunting in the late 1800s may have severely reduced piping plover numbers. The plans did not identify hunting as an existing threat to piping plovers wintering in the U.S., as take is prohibited pursuant to the MBTA. No credible information indicates hunting is a threat in the U.S. or in other countries. Based on the current information, overutilization is not a threat to piping plovers on their wintering and migration grounds. Disease and predation Disease Neither the final listing rule nor the recovery plans state disease is an issue for piping plover, and no plan assigns recovery actions to this threat factor. Based on information available to date, West Nile virus and avian influenza are a minor threat to piping plovers (Service 2009). Predation The effect of predation on migrating or wintering piping plovers remains largely undocumented. Except for one incident involving a cat in Texas(NY Times 2007), no predation of piping plovers during winter or migration has been noted. Avian and mammalian predators are common throughout the species' wintering range. Predatory birds are relatively common during fall and spring migration, and it is possible raptors occasionally take piping plovers(Drake et al. 2001). It has been noted, however,the behavioral response of crouching when in the presence of avian predators may minimize avian predation on piping plovers(Monier and McNeil 1991;Drake 1999b;Drake et al.2001). The 1996 Atlantic Coast Recovery Plan summarized evidence that human activities affect types, abundance,and activity patterns of some predators,thereby exacerbating natural predation on breeding piping plovers. Nonbreeding piping plovers may reap some collateral benefits from predator management conducted for the primary benefit of other species. In 1997,the U.S.Department of Agriculture implemented a public lands predator control partnership in northwest Florida that included the Department of Defense,NPS,the State of Florida(State park lands),and the Service(National Wildlife Refuges and Ecological Services). The program continues with all partners except Florida. In 2008,lack of funding precluded inclusion of Florida State lands;however,DEP staff do occasionally conduct predator trapping on state lands,although trapping is not implemented consistently. The NPS and iiidividtial State park staff ill North Carolina participate in predator control .programs (Rabon 2009). The Service issued permit conditions for raccoon eradication to Indian River County staff in Florida as part of a coastal Habitat Conservation Plan (HCP) (Adams 2009). Destruction of turtle nests by dogs or coyotes in Indian River County justified the need to amend the permit to include an education program targeting dog owners regarding the appropriate means to reduce affects to coastal species caused by their pets. The Service partnered with Texas Audubon and the Coastal Bend Bays and Estuaries Program in Texas to implement predator control efforts on colonial waterbird nesting islands (Cobb 2009). Some of these predator control programs may provide very limited protection to piping plovers should 22 CAC January 10,2013 VII-5 Staff Reports 23 of 64 they use these areas for roosting or foraging(Table 5). The Service is not aware of any current predator control programs targeting protection of coastal species in Georgia, Alabama, Mississippi, or Louisiana. Regarding predation,the magnitude of this threat to non-breeding piping plovers remains unknown, but given the pervasive, persistent, and serious effects of predation on other coastal reliant species, it remains a potential threat. Focused research to confirm these effects as well as to ascertain effectiveness of predator control programs may be warranted, especially in areas frequented by Great Lakes birds during migration and wintering months. The Service considers predator control on their wintering and migration grounds to be a low priority at this time. The threat of direct predation should be distinguished from the threat of disturbance to roosting and feeding piping plovers posed by dogs off leash. Other natural or manmade factors affecting its continued existence Accelerating sea-level rise Over the past 100 years, the globally-averaged sea level has risen approximately 3.9 to 9.8 inches (Rahmstorf 2007), a rate that is an order of magnitude greater than that seen in the past several thousand years (Hopkinson et al. 2008). The Intergovernmental Panel on Climate Change (IPCC) suggests by 2080 sea level rise could convert as much as 33 percent of the world's coastal wetlands to open water(IPCC 2007). Although rapid changes in sea level are predicted, estimated time frames and resulting water levels vary due to the uncertainty about global temperature projections and the rate of ice sheets melting and slipping into the ocean (IPCC 2007; Climate Change Science Program [CCSP] 2008). Potential effects of sea level rise on coastal beaches may vary regionally due to subsidence or uplift as well as the geological character of the coast and nearshore (Galbraith et al. 2002; CCSP 2009). For example, in the last century sea level rise along the U.S. Gulf Coast exceeded the global average by 5.1 to 5.9 inches because coastal lands west of Florida are subsiding (U.S. Environmental Protection Agency [EPA] 2009). Low elevations and proximity to the coast make all nonbreeding coastal piping plover foraging and roosting habitats vulnerable to the effects of rising sea level. Furthermore, areas with small astronomical tidal ranges (e.g., portions of the Gulf Coast where intertidal range is greater than 3.2 feet) are the most vulnerable to loss of intertidal wetlands and flats induced by sea level rise (EPA 2009), Sea level rise was cited as a contributing factor in the 68 percent decline in tidal flats and algal mats in the Corpus Christi area(i.e., Lamar Peninsula to Encinal Peninsula) in Texas between the 1950s and 2004 (Tremblay et al. 2008). Mapping by Titus and Richman (2001)showed that more than 80 percent of the lowest land along the Atlantic and Gulf coasts was in Louisiana,Florida,Texas, and North Carolina,where 73.5 percent of all wintering piping plovers were tallied during the 2006 International Piping Plover Census (Elliott-Smith et al. 2009). Inundation of piping plover habitat by rising seas could lead to permanent loss of habitat if natural coastal dynamics are impeded by numerous structures or roads, especially if those shorelines are also armored with hardened structures. Without development or armoring, low undeveloped islands can migrate toward the mainland, pushed by the overwashing of sand eroding from the seaward side and being redeposited in the bay (Scavia et al. 2002). Overwash 23 CAC January 10,2013 VII-5 Staff Reports 24 of 64 and sand migration are impeded on developed portions of islands. Instead, as sea level increases, the ocean-facing beach erodes and the resulting sand is deposited offshore. The buildings and the sand dunes then prevent sand from washing back toward the lagoons, and the lagoon side becomes increasingly submerged during extreme high tides (Scavia et al. 2002), diminishing both barrier beach shorebird habitat and protection for mainland developments. Modeling for three sea level rise scenarios (reflecting variable projections of global temperature rise)at five important U.S. shorebird staging and wintering sites predicted a loss of 20 to 70 percent of current intertidal foraging habitat(Galbraith et al. 2002). These authors estimated probabilistic sea Ievel changes for specific sites partially based on historical rates of sea level change(from tide gauges at or near each site) which were then superimposed on projected 50 percent and 5 percent probability of global sea level changes by 2100 of 13.4 inches and 30.3 inches, respectively. The 50 percent and 5 percent probability sea level change projections were based on assumed global temperature increases of 35.6° F(50 percent probability)and 40.5° F(5 percent probability). The most severe losses were projected at sites where the coastline is unable to move inland due to steep topography or seawalls. The Galbraith et al. (2002)Gulf Coast study site,Bolivar Flats,Texas,is a designated critical habitat unit known to host high numbers of piping plovers during migration and throughout the winter(e.g., 275 individuals were tallied during the 2006 International Piping Plover Census; Elliott-Smith et al. 2009). Under the 50 percent likelihood scenario for sea level rise, Galbraith et al. (2002)projected approximately 38 percent loss of intertidal flats at Bolivar Flats by 2050; however, after initially losing habitat,the area of tidal flat habitat was predicted to increase slightly by the year 2100,because Bolivar Flats lacks armoring, and the coastline at this site can thus migrate inland. Although habitat losses in some areas are likely to be offset by gains in other locations,Galbraith et al. (2002) noted time lags may exert serious adverse effects on shorebird populations. Furthermore,even if piping plovers are able to move their wintering locations in response to accelerated habitat changes, there could be adverse effects on the birds' survival rates or reproductive fitness. In eight states that support wintering piping plovers, all have the potential for adjacent development and/or hardened shorelines to impede response of habitat to sea level rise (Table 6). Although complete linear shoreline estimates are not readily obtainable, almost all known piping plover wintering sites in the U.S. were surveyed during the 2006 International Piping Plover Census. To estimate effects at the census sites, as well as additional areas where piping plovers have been found outside of the census period, Service biologists reviewed satellite imagery and spoke with other biologists familiar with the sites. Of 406 sites, 204 (50 percent) have adjacent structures that may prevent the creation of new habitat if existing habitat were to become inundated (Table 6). These threats will be perpetuated in places where damaged structures are repaired and replaced, and exacerbated where the height and strength of structures are increased. Data do not exist on the amount or types of hardened structures at wintering sites in the Bahamas, other Caribbean countries,or Mexico. Sea level rise poses a significant threat to all piping plover populations during the migration and wintering portion of their life cycle. Ongoing coastal stabilization activities may strongly influence the effects of sea level rise on piping plover habitat. Improved understanding of how sea level rise may affect the quality and quantity of habitat for migrating and wintering piping plovers is an urgent need. 24 CAC January 10,2013 VII-5 Staff Reports 25 of 64 Contaminants Contaminants have the potential to cause direct toxicity to individual birds or negatively affect their invertebrate prey base (Rattner and Ackerson 2008). Depending on the type and degree of contact, contaminants can have lethal and sub-lethal effects on birds, including behavioral impairment, deformities, and impaired reproduction (Rand and Petrocelli 1985; Gilbertson et al. 1991; Hoffman et al. 1996). The Great Lakes plan states concentration levels of polychlorinated biphenol detected in Michigan piping plover eggs have the potential to cause reproductive harm. They further state analysis of prey available to piping plovers at representative Michigan breeding sites indicated breeding areas along the upper Great Lakes region are not likely the major source of contaminants to this population. In 2000, mortality of large numbers of wading birds and shorebirds occurred following the County's aerial application of the organophosphate pesticide Fenthion for mosquito control purposes, including one piping plover at Audubon's Rookery Bay Sanctuary on Marco Island, Florida, (Williams 2001). Fenthion, a known toxin to birds, was registered for use as an avicide by Bayer chemical manufacturer. Subsequent to a lawsuit filed against the EPA in 2002, the manufacturer withdrew Fenthion from the market, and the EPA declared all uses were to end by November 30,2004 (American Bird Conservancy 2011). All other counties in the U.S. now use less toxic chemicals for mosquito control. It is unknown whether pesticides are a threat for piping plovers wintering in the Bahamas, other Caribbean countries, or Mexico. Petroleum products are the contaminants of primary concern, as opportunities exist for petroleum to pollute intertidal habitats that provide foraging substrate. Beach-stranded 55-gallon barrels and smaller containers, which may fall from moving cargo ships or offshore rigs and are not uncommon on the Texas coast, contain primarily oil products (gasoline or diesel), as well as other chemicals such as methanol, paint, organochlorine pesticides, and detergents (Lee 2009). Federal and state land managers have protective provisions in place to secure and remove the barrels, thus reducing the likelihood of contamination. Effects to piping plovers from oil spills have been documented throughout their life cycle (Chapman 1984; Service 1996; Burger 1997; Massachusetts Audubon 2003; Amirault-Langlais et al. 2007; Amos 2009). This threat persists due to the high volume of shipping vessels (from which most documented spills have originated) traveling offshore and within connected bays along the Atlantic Coast and the Gulf of Mexico. Additional risks exist for leaks or spills from offshore oil rigs, associated undersea pipelines, and onshore facilities such as petroleum refineries and petrochemical plants. Lightly oiled piping plovers have survived and sucLessfully reptwdut;ed (Chapman 1984, Atttitault-Langlais et al. 2007; Amos 2009). Chapman (1984) noted shifts in habitat use as piping plovers moved out of spill areas. This behavioral change was believed to be related to the demonstrated decline in benthic infauna (prey items) in the intertidal zone and may have decreased the direct effects to the species. To date, no plover mortality has been attributed to oil contamination outside the breeding grounds,but latent effects would be difficult to identify. The Deepwater Horizon oil spill, which started April 20, 2010, discharged into the Gulf of Mexico through July 15, 2010. According to government estimates, the leak released between 25 CAC January 10,2013 VII-5 Staff Reports 26 of 64 100 and 200 million gallons of oil into the Gulf. The U.S. Coast Guard estimates that more than 50 million gallons of oil have been removed from the Gulf, or roughly a quarter of the spill amount. Additional effects to natural resources may be attributed to the 1.84 million gallons of dispersant applied to the spill. As of July 2010, approximately 625 miles of Gulf Coast shoreline was oiled (approximately 360 miles in Louisiana, 105 miles in Mississippi,66 miles in Alabama and 94 miles in Florida) (Join Information Center 2010). These numbers reflect a daily snapshot of shoreline that experienced effects from oil; however, they do not include cumulative effects to date, or shoreline that has already been cleaned. Piping plovers have continued to winter within the Gulf of Mexico shorelines. Researchers have and continue to document oiled piping plovers stemming from this spill. Oiling of designated piping plover critical habitat has been documented. Affects to the species and its habitat are expected,but their extent remains difficult to predict. The U.S. Coast Guard, the states, and responsible parties that comprise the Unified Command, with advice from Federal and State natural resource agencies, initiated protective and cleanup efforts per prepared contingency plans to deal with petroleum and other hazardous chemical spills for each state's coastline. The contingency plans identify sensitive habitats, including all federally listed species' habitats,which receive a higher priority for response actions. Those plans allow for immediate habitat protective measures for cleanup activities in response to large contaminant spills. While such plans usually ameliorate the threat to piping plovers, it is yet unknown how much improvement will result in this case given the breadth of the effects associated with the Deepwater Horizon incident. Based on all available data prior to the Deepwater Horizon oil spill, the risk of effects from contamination to piping plovers and their habitat was recognized,but the safety contingency plans were considered adequate to alleviate most of these concerns. The Deepwater Horizon incident has brought heightened awareness of the intensity and extent to fish and wildlife habitat from large-scale releases. In addition to potential direct habitat degradation from oiling of intertidal habitats and retraction of stranded boom, effects to piping plovers may occur from the increased human presence associated with boom deployment and retraction, cleanup activities, wildlife response, and damage assessment crews working along shorelines. Research studies are documenting the potential expanse of effects to the piping plover. Military actions Twelve coastal military bases are located in the Southeast(Table 7). To date, five bases have consulted with the Service under the Act, on military activities on beaches and baysides that may affect piping plovers or their habitat (Table 7). In 2002, Camp Lejeune in North Carolina consulted formally with the Service on troop activities, dune stabilization efforts, and recreational use of Onslow Beach. The permit conditions require bi-monthly(twice-monthly) piping plover surveys, use of buffer zones, and work restrictions within buffer zones. Naval Station Mayport in Duval County,Florida, consulted with the Service on U.S. Marine Corps training activities that included beach exercises and use of amphibious assault vehicles. The affected area was not considered optimal for piping plovers and the consultation was concluded informally. Similar informal consultations have occurred with Tyndall Air Force Base (Bay County) and Eglin Air Force Base (Okaloose and Santa Rosa Counties) in northwest Florida. Both consultations dealt with occasional use of motorized equipment on the beaches 26 CAC January 10,2013 VII-5 Staff Reports 27 of 64 and associated baysides. Tyndall Air Force Base has minimal on-the-ground use, and activities, when conducted, occur on the Gulf of Mexico beach, which is not considered the optimal area for piping plovers within this region. Eglin Air Force Base conducts bi-monthly (twice-monthly) surveys for piping plovers, and habitats consistently documented with piping plover use are posted with avoidance requirements to minimize direct disturbance from troop activities. A 2001 consultation with the Navy for training exercises on the beach and retraction operations on Peveto Beach, Cameron Parish, Louisiana, concluded informally. Overall,project avoidance and minimization actions currently reduce threats from military activities to wintering and migrating piping plovers to a minimal threat level. However,prior to removal of the piping plover from protection of the Act, Integrated Resource Management Plans or other agreements should clarify if and how a change in legal status would affect plover protections. Recreational disturbance Intense human disturbance in shorebird winter habitat can be functionally equivalent to habitat loss if the disturbance prevents birds from using an area(Goss-Custard et al. 1996), which can lead to roost abandonment and local population declines (Burton et al. 1996). Pfister et al. (1992) implicated anthropogenic disturbance as a factor in the long-term decline of migrating shorebirds at staging areas. Disturbance (i.e., human and pet presence) that alters bird behavior can disrupt piping plovers as well as other shorebird species. Disturbance can cause shorebirds to spend less time roosting or foraging and more time in alert postures or fleeing from the disturbances (Johnson and Baldassarre 1988; Burger 1991, 1994;Elliott and Teas 1996; Lafferty 2001a, 2001 b;Thomas et al. 2002), which limits the local abundance of piping plovers (Zonick and Ryan 1996; Zonick 2000). Shorebirds that are repeatedly flushed in response to disturbance expend energy on costly short flights (Nudds and Bryant 2000). Shorebirds are more likely to flush from the presence of dogs than people, and birds react to dogs from farther distances than people(Lafferty 2001a, 200lb;Thomas et al. 2002). Dogs off leash are more likely to flush piping plovers from farther distances than dogs on leash. Nonetheless,dogs both on and off leashes disturb piping plovers (Hoopes 1993). Pedestrians walking with dogs often go through flocks of foraging and roosting shorebirds; some even encourage their dogs to chase birds. Off-road vehicles can significantly degrade piping plover habitat (Wheeler 1979) or disrupt the birds' normal behavior patterns (Zonick 2000). The 1996 Atlantic Coast recovery plan cites tire ruts crushing wrack into the sand, making it unavailable as cover or as foraging substrate (Goldin 1993b; Hoopes 1993). The plan also notes the magnitude of the threat from off-road vehicles is particularly significant because vehicles extend the effects to remote stretches of beach where human disturbance would otherwise be very slight. Lamont at al. (1997) postulated vehicular traffic along the beach may compact the substrate and kill marine invertebrates that are food for the piping plover. Zonick (2000) found the density of off-road vehicles negatively correlated with abundance of roosting piping plovers on the ocean beach. Cohen et al. (2008) found radio- tagged piping plovers using ocean beach habitat at Oregon Inlet in North Carolina were far less likely to use the north side of the inlet where off-road vehicle use is allowed, and recommended controlled management experiments to determine if recreational disturbance drives roost site selection. Ninety-six percent of piping plover detections were on the south side of the inlet even though it was farther away from foraging sites (1.1 miles from the sound side foraging site to the 27 CAC January 10,2013 VII-5 Staff Reports 28 of 64 north side of the inlet versus 0.2 mile from the sound side foraging site to the north side of the inlet; Cohen et al. 2008). Based on surveys with land managers and biologists, knowledge of local site conditions, and other information, the Service estimated the levels of eight types of disturbance at sites in the U.S.with wintering piping plovers. There are few areas used by wintering piping plovers that are devoid of human presence, and just under half have leashed and unleashed dog presence (Smith 2007; Lott et al. 2009;Maddock and Bimbi unpublished data;Table 8). Data are not available on human disturbance at wintering sites in the Bahamas,other Caribbean countries,or Mexico. Although the timing, frequency, and duration of human and dog presence throughout the wintering range are unknown, studies in Alabama and South Carolina suggest that most disturbances to piping plovers occur during periods of warmer weather, which coincides with piping plover migration (Johnson and Baldassarre 1988; Lott et al. 2009; Maddock et al. 2009). Smith (2007) documented varying disturbance levels throughout the nonbreeding season at northwest Florida sites. In South Carolina, 33 percent (13 out of 39) of sites surveyed during the 2007 and 2008 season had>_ 5 birds. Of those 13 sites,46.2 percent (6 out of 13) had>10 people present during surveys, and 61.5 percent (8 out of 13)allow dogs, indicating that South Carolina sites with the highest piping plover density are exposed to disturbance. Only 25.7 percent (9 out of 35) of sites in South Carolina prohibit dogs and restrict public access to the entire site or sections of sites used by piping plovers (Maddock and Bimbi unpublished data). Compliance with the restrictions at these sites is unknown. LeDee (2008)collected survey responses in 2007 from 35 managers (located in 7 states) at sites . that were designated as critical habitat for wintering piping plovers. Ownership included Federal, State, and local governmental agencies and nongovernmental organizations managing National Wildlife Refuges; national, state, county, and municipal parks; state and estuarine research reserves; state preserves; state wildlife management areas; and other types of managed lands. Of 44 reporting sites,40 allowed public beach access year-round and 4 sites were closed to the public. Of the 40 sites that allow public access,62 percent of site managers reported greater than 10,000 visitors during September through March, and 31 percent reported greater than 100,000 visitors. Restrictions on visitor activities on the beach included automobiles(81 percent), all-terrain vehicles (89 percent), and dogs (50 percent) during the winter season. Half of the survey respondents reported funding as a primary limitation in managing piping plovers and other threatened and endangered species at their sites. Other limitations included "human resource capacity" (24 percent),conflicting management priorities (12 percent), and lack of research (3 percent). Disturbance can be addressed by implementing recreational management.techniques such as vehicle and pet restrictions and symbolic fencing (usually sign posts and string) of roosting and feeding habitats. In implementing conservation measures, managers need to consider a range of site specific factors, including the extent and quality of roosting and feeding habitats, and the types and intensity of recreational use patterns. In addition,educational materials such as informational signs or brochures can provide valuable information so that the public understands the need for conservation measures. 28 • CAC January 10,2013 VII-5 Staff Reports 29 of 64 In summary, although there is some variability among states, disturbance from human beach recreation and pets pose a moderate to high and escalating threat to migrating and wintering piping plovers. Systematic review of recreation policy and beach management across the nonbreeding range will assist in better understanding cumulative effects. Site specific analysis and implementation of conservation measures should be a high priority at piping plover sites that have moderate or high levels of disturbance, and the Service and state wildlife agencies should increase technical assistance to land managers to implement management strategies and monitor their effectiveness. Storm events Although coastal piping plover habitats are storm-created and maintained, the 1996 Atlantic Coast Recovery Plan also noted that storms and severe cold weather may take a toll on piping plovers,and the 2003 Great Lakes Recovery Plan postulated that loss of habitats such as overwash passes or wrack, where birds shelter during harsh weather, poses a threat. Storms are a component of the natural processes that form coastal habitats used by migrating and wintering piping plovers,and positive effects of storm-induced overwash and vegetation removal have been noted in portions of the wintering range. For example,Gulf Islands National Seashore habitats in Florida benefited from increased washover events that created optimal habitat conditions during the 2004 and 2005 hurricane seasons,with biologists reporting piping plover use of these habitats within 6 months of the storms (Nicholas 2005). In 2005,Hurricane Katrina overwashed the mainland beaches of Mississippi,creating many tidal flats where piping plovers were subsequently observed(Winstead 2008). Hurricane Katrina also created a new inlet and improved habitat conditions on some areas of Dauphin Island,Alabama(LeBlanc 2009). Conversely, localized storms, since Katrina,have induced habitat losses on Dauphin Island (LeBlanc 2009). Noel and Chandler(2005) suspect that changes in habitat caused by multiple hurricanes along the Georgia coastline altered the spatial distribution of piping plovers and may have contributed to winter mortality of three Great Lakes piping plovers. Following Hurricane Ike in 2008, Arvin (2009) reported decreased numbers of piping plovers at some heavily eroded Texas beaches in the center of the storm affected area and increases in plover numbers at sites about 100 miles to the southwest. However, piping plovers were observed later in the season using tidal lagoons and pools that Ike created behind the eroded beaches (Arvin 2009). The adverse effects on piping plovers attributed to storms are sometimes due to a combination of storms and other environmental changes or human use patterns. For example, four hurricanes between 2002 and 2005 are often cited in reference to rapid erosion of the Chandeleur Islands, a chain of low-lying islands in Louisiana where the 1991 International Piping Plover Census tallied more than 350 piping plovers. Comparison of imagery taken 3 years before and several days after Hurricane Katrina found the Chandeleur Islands lost 82 percent of their surface area (Sallenger et al. in review), and a review of aerial photography prior to the 2006 Census suggested little piping plover habitat remained (Elliott-Smith et al. 2009). However, Sallenger et . al. (in review) noted habitat changes in the Chandeleur Islands stem not only from the effects of these storms,but rather from the combined effects of the storms,long-term (greater than 1,000 years) diminishing sand supply, and sea level rise relative to the land. 29 CAC January 10,2013 VII-5 Staff Reports 30 of 64 Other storm-induced adverse effects include poststorm acceleration of human activities such as beach nourishment,sand scraping,and berm and seawall construction. Such stabilization activities can result in the loss and degradation of feeding and resting habitats. Storms can also cause widespread deposition of debttis along beaches. Removal of debris often requires large machinery,which can cause extensive disturbance and adversely affect habitat elements such as wrack. Another example of indirect adverse effects linked to a storm event is the increased access to Pelican Island(LeBlanc 2009)due to merging with Dauphin Island following a 2007 storm(Gibson et al. 2009). Recent climate change studies indicate a trend toward increasing hurricane numbers and intensity (Emanuel 2005; Webster et al. 2005). When combined with predicted effects of sea level rise, there may be increased cumulative effects from future storms. In summary, storms can create or enhance piping plover habitat while causing localized losses elsewhere in the wintering and migration range. Available information suggests some birds may have resiliency to storms and move to unaffected areas without harm, while other reports suggest birds may perish from storm events. Significant concerns include disturbance to piping plovers and habitats during cleanup of debris, and poststorm acceleration of shoreline stabilization activities which can cause persistent habitat degradation and loss. Summary Habitat loss and degradation on winter and migration grounds from shoreline and inlet stabilization efforts, both within and outside of designated critical habitat, remains a serious threat to all piping plover populations. In some areas,beaches that abut private property are needed by wintering and migrating piping plovers. However, residential and commercial developments that typically occur along private beaches may pose significant challenges for efforts to maintain natural coastal processes. The threat of habitat loss and degradation, combined with the threat of sea level rise associated with climate change, raise serious concerns regarding the ability of private beaches to support piping plovers over the long term. Future actions taken on private beaches will determine whether piping plovers continue to use these beaches or whether the recovery of piping plovers will principally depend on public property. As Lott (2009)concludes,"The combination of development and shoreline protection seems to limit distribution of non-breeding piping plovers in Florida. If mitigation or habitat restoration efforts on barrier islands fronting private property are not sufficient to allow plover use of some of these areas,the burden for plover conservation will fall almost entirely on public land managers," While public lands may not be at risk of habitat loss from private development, significant threats to piping plover habitat remain on many municipal, state, and federally owned properties, These public lands may be managed with competing missions that include conservation of imperiled species, but this goal frequently ranks below providing recreational enjoyment to the public, readiness training for the military, or energy development projects. Public lands remain the primary places where natural coastal dynamics are allowed. Of recent concern are requests to undertake beach nourishment actions to protect coastal roads or military infrastructure on public lands. If project design does not minimize impediments to shoreline overwash, which are necessary to help replenish bayside tidal flat sediments and elevations, significant bayside habitat may become vegetated or inundated, thereby exacerbating the loss of 30 CAC January 10,2013 VII-5 Staff Reports 31 of 64 preferred piping plover habitat. Conversely, if beach fill on public lands is applied in a way that allows for"normal" system overwash processes, and sediment is added back to the system, projects may be less injurious to barrier island species that depend on natural coastal dynamics. Maintaining wrack for food and cover in areas used by piping plovers may help offset effects that result from habitat degradation due to sand placement associated with berm and beach nourishment projects and ensuing human disturbance. Leaving wrack on private beaches may improve use by piping plovers, especially during migration when habitat fragmentation may have a greater effect on the species. In addition, using recreation management techniques, Great Lakes recovery action 2.14 may minimize the effects of habitat loss. Addressing off-road vehicles and pet disturbance may increase the suitability of existing piping plover habitat. Analysis of the species/critical habitat likely to be affected In a letter dated April 12, 2012, the Corps determined the proposed project"may affect" the threatened loggerhead sea turtle,endangered leatherback sea turtle,endangered green sea turtle, endangered hawksbill sea turtle, and endangered Kemp's ridley sea turtle, and"may affect, but is not likely to adversely affect,"the endangered West Indian manatee. On August 22, 2011, the Service issued a Statewide Programmatic Biological Opinion (SPBO) to the Corps to address potential adverse effects to nesting sea turtles and the West Indian manatee as a result of sand placement activities proposed along the coast of Florida(Service 2011). The SPBO includes avoidance and minimization measures, Reasonable and Prudent Measures, and Terms and Conditions to ensure adverse effects to the covered species are avoided and minimized to the maximum extent practicable. The proposed activities associated with maintenance dredging of Wiggins Pass navigation channel and sand placement are covered in the SPBO, and the Corps and Applicant have agreed to implement the protection measures described in the SPBO. Therefore, the Service has determined the proposed project is consistent with the SPBO, and the Service concurs with the Corps' determinations. The Reasonable and Prudent Measures and Terms and Conditions in section A of the SPBO will apply to the Corps and Applicant. This concludes our consultation for nesting sea turtles and West Indian manatees. Beach mice are not present in the action area. Based on this information, the Service concurs with the Corps' determinations listed above. The proposed action has the potential to adversely affect wintering and migrating piping plovers and their habitat from all three populations that may use the action area. The Atlantic Coast nesting population of piping plover is a component of the entity listed as threatened, which encompasses all breeding piping plovers (Great Plains and Atlantic)except the Great Lakes breeding population. Therefore, this Biological Opinion considers the potential effects of this project on this species and its designated critical habitat. ENVIRONMENTAL BASELINE Status of the species/critical habitat within the action area There is no federally designated piping plover critical habitat within the project area. The closest critical habitat units for wintering piping plovers are Units FL-26 and FL-27. Unit FL-26 is located on Estero Island in Lee County, approximately 8 miles north of the project area, and 31 CAC January 10,2013 VII-5 Staff Reports 32 of 64 FL-27 is located on Tigertail Beach, at the entrance to Big Marco Pass, approximately 22 miles south of the project area Informal observations of bird populations in and adjacent to Wiggins Pass are conducted by staff and volunteers at Delnor-Wiggins Pass State Park and Barefoot Beach Preserve. According to the 2007 Barefoot Beach Land Management Plan, piping plovers were observed by park rangers (no additional details available). Launched in 2002 by the Cornell Lab of Ornithology and National Audubon Society, eBird provides data concerning bird abundance and distribution at a variety of spatial and temporal scales. eBird is sponsored in part by several Service programs, research groups, non-government offices, and the University of the Virgin Islands. According to eBird, no piping plovers were observed along Barefoot Beach Preserve or Delnor-Wiggins Pass State Park (to the north and south of Wiggins Pass,respectively) between 2008 and 2012. Efforts to avoid and reduce adverse effects The Service often requests postproject surveys and eradication of coastal exotic plant species in Florida as permit conditions for beach berm or nourishment projects to reduce effects to piping plover habitat. Four recent Biological Opinions for sand placement events in Florida included requirements that restricted the removal of wrack to minimize project effects (Service 2007b, 2008c, 2008d, 2008e). A statewide consultation with the Federal Emergency Management Agency to minimize emergency berm repair and construction projects in Florida was completed in 2008 (Service 2008c). Section 10(a)(2)(A) of the Act requires an applicant for an incidental take permit to submit a conservation plan that specifies, among other things,the effects that are likely to result in the taking and the measures the applicant will undertake to minimize and mitigate such effects. Coordinated efforts for several large projects are currently underway. Florida Service field offices are engaged in statewide programmatic consultations on Florida coastal Corps projects and permitting (dredging,jetty maintenance, and nourishment). Also, DEP and FWC are drafting a statewide HCP for coastal actions permitted through the DEP. The primary purpose of this plan is to minimize or mitigate habitat affects associated with wrack removal, seawall installation, and geotube placement. As noted above, some project sponsors have incorporated recommended avoidance and minimization measures. Nonetheless, considerable challenges remain. Other project sponsors have declined to implement Service conservation recommendations, citing financial costs and engineering restrictions. Several projects have resulted in formal consultation for piping plovers or their designated critical habitat in Florida (Table 9). Factors affecting the species environment within the action area Since 1984, approximately 50,000 cy of beach compatible material has been dredged every 2 years from Wiggins Pass and placed north and south of the Pass in the nearshore waters of Barefoot Beach Preserve and Wiggins Pass State Park,with occasional placement on the beach of Delnor- Wiggins. The most recent dredging and sand placement event took place in 2011. 32 CAC January 10,2013 VII-5 Staff Reports 33 of 64 Based on maintenance dredging and sand placement activities,piping plovers have the potential to be affected due to habitat loss, sand placement, wrack removal,predation,contaminants, recreational disturbance,and storm events within the action area. EFFECTS OF THE ACTION Factors to be considered Beach topography and morphology The geomorphic characteristics of barrier islands, peninsulas,beaches, dunes, overwash fans, and inlets are critical to a variety of natural resources, and the geomorphic characteristics influence a barrier beach's ability to respond to wave action, including storm overwash and sediment transport. However, the protection or persistence of these important natural land forms, processes, and wildlife resources is often in conflict with shoreline projects. The manufactured berms and sand fill may impede overwash, thereby causing successional advances in the habitat that will reduce sand flat formation, and, therefore, its use by piping plovers in the project area. Distribution The Applicant proposes dredging and sand placement activities within the authorized Wiggins Pass navigational channel and along the shoreline between DEP reference monuments R-12 to R-15.5 and R-18 to R-20,respectively. The Service expects the proposed construction activities could directly and indirectly affect the distribution of migrating and wintering piping plovers to roosting and foraging habitat within the action area. Disturbance frequency and intensity The proposed action has the potential to adversely affect piping plovers within the proposed action area during dredging and sand placement activities. Dredging and sand placement are proposed to take place between November 1 and April 30 in order to avoid peak sea turtle nesting season. The Service anticipates construction activities to have short-term and temporary effects on the piping plover populations. Piping plovers located within the action area are expected to move outside of the construction zone due to disturbance. Duration The timeframe associated with completion of the initial dredging and sand placement event is expected to be approximately 75 days,working 24 hours per day, 7 days per week. That Said, the timeframe may vary depending on the amount of work necessary, weather conditions, equipment mobilization and maintenance, and permit conditions. For subsequent maintenance dredging events, a 45 day timeframe is anticipated for completion. Commencement of the upcoming dredge and sand placement event is scheduled to occur in 2013. Nature of the effect Although the Service expects short-term effects from disturbance during project construction, it is anticipated that the action will result in direct, indirect, and long term effects to piping plovers. 33 CAC January 10,2013 VII-5 Staff Reports 34 of 64 The Service expects there may be morphological changes to piping plover habitat due to the effects to loafing and foraging habitat, and optimal habitat within the action area. Activities that affect or alter the use of optimal habitat, or increase disturbance to the species, may decrease the survival and recovery potential of the piping plover. Timing The timing of the proposed dredging and sand placement project may occur completely or partially during the migration and wintering period for piping plovers (July 15 to May 15). The Service expects indirect effects to occur later in time. Analyses for effects of the action The proposed project includes dredging approximately 95,000 cy of beach compatible material from the authorized Wiggins Pass navigational channel and placing it along 1.15 miles of shoreline. If the dredged material is placed on the beach, it has the potential to elevate the beach berm and widen the beach, providing storm protection and increasing recreational space. Sand placement may occur in and adjacent to habitat that appears suitable for roosting and foraging piping plovers or that will become more optimal with time. Project construction may overlap with portions of piping plover winter and migration seasons. Short-term and temporary construction effects to piping plovers will occur if the birds are roosting and feeding in the area during a migration stopover. The deposition of sand may temporarily deplete the intertidal food base along the shoreline and temporarily disturb roosting birds during project construction. Tilling to loosen compaction of the sand (required to minimize sea turtle effects) may affect wrack that has accumulated on the beach. This affects feeding and roosting habitat for piping plovers since they often use wrack for cover and foraging. Direct effects The construction window (i.e., sand placement, dredging) for each dredging event will extend through a portion of one piping plover migration and winter season. If the dredged material is placed on the beach, heavy machinery and equipment (e.g., trucks and bulldozers), location of the dredge pipeline, and sand placement, may adversely affect migrating and wintering piping plovers in the action area by disturbing and disrupting normal activities such as roosting and feeding, and possibly forcing birds to expend valuable energy reserves to seek available habitat in adjacent areas along the shoreline. In addition, suffocation of invertebrate species will occur. Impacts will affect the entire fill template (1.15 miles) along the project area. Timeframes projected for benthic recruitment and re-establishment following sand placement are between 6 months and 2 years, depending on actual recovery rates. Effects will occur even if sand placement activities occur outside the piping plover migration and wintering seasons. Indirect effects The proposed project includes placing beach-compatible material dredged from the authorized Wiggins Pass navigational channel along 1.15 mile of shoreline between DEP reference monuments R-12 to R-15.5 and R-18 to R-20. Indirect effects of reducing the potential for the formation of optimal habitats, especially along the shoreline, pose a concern to piping plover survival and recovery within the action area. 34 CAC January 10,2013 VII-5 Staff Reports 35 of 64 Eventually the shoreline within the fill template will reestablish and provide some feeding habitat for piping plovers, but these feeding areas are considered inferior to natural overwash and emergent shoal habitat that is likely to form within sections of the action area absent the proposed project. Natural barrier islands need storms and overwash in order to maintain the physical and biological environments they support(Young et al. 2006). The removal of overwash processes will accelerate the successional state of the flats such that they will likely become vegetated within a few years (Leatherman 1988),thereby reducing the area's value to foraging and roosting piping plovers. The proposed project will perpetuate and contribute to the widespread activities that prevent the formation of these preferred early successional overwash habitats. The piping plover's rapid response to habitats formed by washovers from the hurricanes in 2004 and 2005 in the Florida panhandle at Gulf Islands National Seashore and Eglin Air Force Base's Santa Rosa Island, and similar observations of their preferences for overwash habitats at Phipps Preserve and Lanark Reef in Franklin County, Florida, and elsewhere in their range, demonstrate the importance of optimal habitats for wintering and migrating piping plovers. At the same time the proposed project limits the creation of optimal foraging and roosting habitat, it increases recreational pressures within the project area. Recreational activities that have the potential to adversely affect piping plovers include disturbance by increased pedestrian use, often with dogs. Long-term effects could include a decrease in piping plover use of habitat due to increased disturbance levels. Dredging of Wiggins Pass navigational channel will potentially allow for an increase in boat traffic. Boating related activities,the associated pedestrian presence and possible domestic canine presence, may adversely affect the foraging and roosting behavior of piping plovers. Beneficial effects There are no known beneficial effects to piping plovers or piping plover habitat from the proposed project. Species' response to the proposed action The Service bases this Biological Opinion on anticipated direct and indirect effects to piping plovers (wintering and migrating) as a result of maintenance dredging of the authorized Wiggins Pass navigation channel and sand placement, which prevents the maintenance or formation of habitat that piping plovers consider optimal for foraging and roosting. Heavy machinery and equipment, the placement of the dredge pipeline along the beach, and sand disposal may adversely affect migrating and wintering piping plovers in the project area by causing disturbance and disruption of normal activities such as roosting and foraging, and possibly forcing piping plovers to expend valuable energy reserves to seek available habitat elsewhere. In addition, foraging in suboptimal habitat by migrating and wintering piping plovers may reduce the fitness of individuals. 35 CAC January 10,2013 VII-5 Staff Reports 36 of 64 • CUMULATIVE EFFECTS Cumulative effects include the effects of future State,Tribal, local, or private actions that are reasonably certain to occur in the action area considered in this Biological Opinion. Future Federal actions that are unrelated to the proposed action are not considered in this section because they require separate consultation pursuant to section 7 of the Act. The Applicant does not anticipate conducting additional activities in the project action area that could affect federally listed species other than the dredging and sand placement events outlined in this Biological Opinion. Any other activities in the action area would require a Corps permit. Therefore, no cumulative effects are expected. CONCLUSION The 1.15 miles of shoreline represents approximately 0.05 percent of the 2,340 miles of sandy beach shoreline available (although not necessarily suitable)throughout the piping plover wintering range within the conterminous U.S. The Service estimates 29 percent(668 miles pre-project)have permits for sand placement events. After reviewing the current status of the northern Great Plains, Great Lakes, and Atlantic Coast wintering piping plover populations, the environmental baseline for the dredging, sand placement, associated construction activities, and the cumulative effects, it is the Service's biological opinion that implementation of the project, as proposed, is not likely to jeopardize the continued existence of the piping plover, and no critical habitat will be affected. INCIDENTAL TAKE STATEMENT Section 9 of the Act and Federal regulation pursuant to section 4(d) of the Act prohibit the take of endangered or threatened species without special exemption. Take is defined as to harass, harm, pursue, hunt,shoot, wound, kill, trap,capture or collect, or to attempt to engage in any such conduct. Harm is further defined by the Service to include significant habitat modification or degradation that results in death or injury to listed species by significantly impairing essential behavioral patterns, including breeding, feeding, or sheltering. Harass is defined by the Service as intentional or negligent actions that create the likelihood of injury to listed species to such an extent as to significantly disrupt normal behavior patterns which include,but are not limited to, breeding, feeding, or sheltering. Incidental take is defined as take that is incidental to, and not the purpose of, carrying out an otherwise lawful activity. Under the terns of section 7(b)(4) and section 7(o)(2),taking that is incidental to and not intended as part of the agency action is not considered to be prohibited under the Act provided that such taking is in compliance with the terms and conditions of this incidental take statement. The measures described below are nondiscretionary, and must be implemented by the Corps so they become binding conditions of any permit issued, as appropriate, for the exemption in section 7(o)(2) to apply. The Corps has a continuing duty to regulate the activity covered by this incidental take statement. If the Corps (1) fails to assume and implement the Terms and Conditions or, (2)fails to adhere to the Terms and Conditions of the incidental take statement 36 CAC January 10,2013 VII-5 Staff Reports 37 of 64 through enforceable terms that are added to the permit, the protective coverage of section 7(o)(2) may lapse. In order to monitor the effects of incidental take, the Corps must report the progress of the action and its effects on the species to the Service as specified in the incidental take statement [50 CFR §402.14(i)(3)]. AMOUNT OR EXTENT OF TAKE It is difficult for the Service to estimate the exact number of piping plovers that could be migrating through or wintering within the proposed action area at any one point in time or place during project construction. Therefore, the Service considers the disturbance to shoreline miles as a measurable way to estimate take because disturbance to suitable habitat within the action area would affect the ability of any given number of piping plovers to find foraging and roosting habitat throughout the migrating and wintering periods of any given year. The Service anticipates an unspecified number of piping plovers occupying 1.15 miles of shoreline (between DEP reference monuments R-12 to R-15.5 and R-18 to R-20) and 15.8 acres within the maintenance dredge template could be taken in the form of harm (e.g., death, injury) and harassment as a result of the proposed project. The amount or extent of incidental take for piping plovers will be considered exceeded if the frequency of channel dredging and sand placement events over the course of the 10-year Corps permit exceeds more than one every 4 years, with the exception of intermediate spot dredging as needed with fill placement in the ebb shoal disposal area. This incidental take statement will expire 10 years from the date of Corps permit issuance. If, during the course of the action, this level of incidental take is exceeded, such incidental take represents new information requiring reinitiation of consultation and review of the reasonable and prudent measures provided. The Corps must immediately provide an explanation of the causes of the taking and review with the Service the need for possible modification of the reasonable and prudent measures. EFFECT OF THE TAKE In this Biological Opinion, the Service determined the proposed project is not likely to result in jeopardy to piping plovers or result in destruction or adverse modification of critical habitat. REASONABLE AND PRUDENT MEASURES The Service believes the following reasonable and prudent measures are necessary and appropriate to minimize take of nonbreeding piping plovers in the proposed action area. . ... ... . . . . ... . ... . . .. . 1. The Applicant shall minimize and monitor the effects of the proposed project on piping plovers. 2. After project completion, the Applicant shall protect wrack and inlet shorelines for roosting and foraging piping plovers. 3. Preconstruction project information collected in Term and Condition#1 shall be submitted to the South.Florida Ecological Services Office. 37 CAC January 10,2013 VII-5 Staff Reports 38 of 64 4. Prior to construction, avoidance signs shall be installed around optimal piping plover habitat features. 5. Driving on the beach shall be limited to that necessary and within a travel corridor. 6. Postconstruction signage will be placed within the action area to protect piping plover habitat features. 7. The Applicant shall educate the public to minimize disturbance to piping plovers. 8. The Applicant shall comply with the MBTA and FWC's shorebird guidelines. 9. The Applicant shall minimize the presence of predators. 10. The Corps shall ensure communication between all parties is carried out. TERMS AND CONDITIONS In order to be exempt from the prohibitions of section 9 of the Act, the Corps and Applicant must comply with the following terms and conditions, which implement the reasonable and prudent measures described above, and outline required reporting and monitoring requirements. These terms and conditions are nondiscretionary. 1. For 3 months prior to construction and for the 3 years following each dredging and sand placement event, the Applicant must conduct bi-monthly (twice-monthly) surveys for piping plovers in the beach fill and dredging templates within the action area covering the nonbreeding season for plovers (July 15 to May 15 of each year) to monitor and quantify the level of take associated with the project and to evaluate the potential effects of future projects of similar nature. At least one of the bi-monthly surveys should be conducted on a weekend during each of the months of October, November, March and April. Piping plover identification,especially when in non-breeding plumage, can be difficult. Qualified professionals with shorebird/habitat survey experience must conduct the required field work. The following will be collected and reported: .. ........... . a. Negative and positive survey data; .. b. The amount and type of recreational use (e.g., people, dogs on-off leash, vehicles, kite-boarders); c. Piping plover locations with a Global Positioning System (decimal degrees preferred); d. Habitat feature(s) used by piping plovers when observed (e.g., intertidal, fresh wrack, old wrack, dune, mid-beach, vegetation); e. Landscape feature(s) where piping plovers are located (e.g., inlet spit, tidal creek, shoals, lagoon shoreline); 38 CAC January 10,2013 VII-5 Staff Reports 39 of 64 f. Substrate used by piping plovers(e.g., sand, mud/sand, mud, algal mat); g. Behavior of piping plovers (e.g., foraging, roosting, preening,bathing, flying, aggression, walking); h. Color bands observed on piping plovers; and i. All other shorebirds/waterbirds seen within the survey area. All information shall be incorporated into a database. Submit pre-and postconstruction piping plover monitoring results (datasheets, maps, database) on standard electronic media(e.g., CD,DVD) to the FWC, and to the Service's South Florida Ecological Services Office (1339 20th Street,Vero Beach, Florida 32960-3559; 772-562-3909). All reports will be due by December 1 following the end of the nonbreeding season for plovers (July 15) of each year. 2. To preserve piping plover feeding and roosting habitat, the Applicant shall limit mechanical cleaning of the dry sand portion of the beach to areas landward of the primary wrack (organic material) line as reasonable determined by the Applicant for the life of the project. This has been identified as important foraging and roosting habitat by piping plovers as well as an abundance of other shorebirds for wintering and migrating. Trash and litter within the wrack line area may be manually removed. Mechanical removal of wrack may be authorized when the Applicant documents a fish kill event, or when the health of humans may be affected. The Applicant will notify the Service via phone or electronic mail when wrack removal is necessary. 3. Prior to construction, the Applicant shall submit to the South Florida Ecological Services Office a project design which incorporates the information collected in Term and Condition#1 documenting how project impacts have been minimized to the maximum extent practicable. 4. Prior to construction, the Applicant shall post avoidance signs around any optimal piping plover habitat features identified in Term and Condition#1 within the project area, and protect these areas from sediment fill to the maximum extent practicable. Obvious identifiers (e.g., pink flagging tape on metal poles) shall be used to clearly mark the boundaries to prevent accidental impacts to these areas. 5. If project construction requires driving on the beach outside of the project area, driving on the beach for construction shall be limited to the minimum necessary within a travel corridor established above the primary wrack line. 6. Postconstruction signage shall be placed within the action area to protect the habitat features documented as used by piping plovers. When County pet ordinances are in place,that information shall be integrated into the signage. If possible, warnings and citations will be issued when appropriate to minimize harassment of piping plovers and other shorebirds protected under the MBTA. 39 CAC January 10,2013 • VII-5 Staff Reports 40 of 64 7. The Applicant shall produce piping plover and wrack-oriented educational materials to be placed on the County's website and television channel. The goal of these outreach activities is to educate the public about piping plover optimal habitat,the role of natural coastal processes in creating and maintaining piping plover habitat, and the importance of wrack. Some of the educational information will be included in a preconstmct.ion news release. 8. Due to the potential for the proposed project to affect piping plovers, the Applicant shall comply with the MBTA and follow FWC's standard guidelines to protect against effects to nesting shorebirds during implementation of the proposed project from February 15 to August 31. In part,these guidelines include the establishment of buffer zones in locations where shorebirds have been engaged in nesting behavior, including territory defense. 9. The Applicant shall ensure the contractors conducting the work provide predator proof trash receptacles for all construction workers. All contractors and their employees shall be briefed on the importance of not littering and keeping the project area trash and debris free. Predator proof trash receptacles shall be installed and maintained at all access points,eating areas, and restroom areas. 10. The Corps shall submit a report describing the actions taken to implement the terms and conditions of this incidental take statement to the FWC, Imperiled Species Management Section,Tallahassee office and the Service's South Florida Ecological Services Office, Vero Beach, Florida, within 60 days postconstruction of each event. 11. The Corps must arrange a meeting between representatives of the contractor, the Service, the FWC, and the shorebird surveyor(s)prior to the commencement of the project and prior to each future event. Upon locating a dead, injured, or sick threatened or endangered specimen, initial notification must be made to the Service's Office of Law Enforcement (20501 Independence Boulevard, Groveland, Florida 34736; 352-429-1037). Additional notification must be made to FWC at 1-888-404-3922 and the Service's South Florida Ecological Services Office (1339 20th Street, Vero Beach, Florida 32960-3559; 772-562-3909). Care should be taken in handling sick or injured specimens to ensure effective treatment and care and in handling dead specimens to preserve biological materials in the best possible state for later analysis of cause of death. In conjunction with the care of sick or injured endangered or threatened species or preservation of biological materials from a dead animal, the finder has the responsibility to ensure evidence intrinsic to the specimen is not unnecessarily disturbed. CONSERVATION RECOMMENDATIONS Section 7(a)(1) of the Act directs Federal agencies to utilize their authorities to further the purposes of the Act by carrying out conservation programs for the benefit of endangered and threatened species. Conservation recommendations are discretionary agency activities to minimize or avoid adverse effects of a proposed action on listed species or critical habitat, to help implement recovery plans, or to develop information. 40 CAC January 10,2013 VII-5 Staff Reports 41 of 64 • To further protect piping plover habitat and reduce beach erosion, the Applicant should consider protecting the wrack throughout the project area in perpetuity. In order for the Service to be kept informed of actions minimizing or avoiding adverse effects or benefiting listed species or their habitats, the Service requests notification of the implementation of any conservation recommendations. THE MIGRATORY BIRD TREATY ACT The MBTA implements various treaties and conventions between the U.S., Canada,Japan, Mexico, and the former Soviet Union for the protection of migratory birds. Under the provisions of the MBTA, it is unlawful "by any means or manner to pursue, hunt, take,capture or kill any migratory bird except as permitted by regulations issued by the Service." The term "take" is not defined in the MBTA, but the Service has defined it by regulation to mean to pursue,hunt, shoot, wound,kill,trap,capture or collect any migratory bird, or any part, nest or egg or any migratory bird covered by the conventions or to attempt those activities. In order to comply with the MBTA,and due to the potential for this project to affect nesting shorebirds, the Corps and Sponsor should follow FWC's standard guidelines to protect against effects to nesting shorebirds during implementation of this project from February 15 to August 31. The Service will not refer the incidental take of piping plover for prosecution under the MBTA of 1918, as amended (16 U.S.C. 703-712), if such take is in compliance with the terms and conditions specified in the incidental take statement above. REINITIATION NOTICE This concludes formal consultation on the action outlined in the request. As provided in 50 CFR §402.16, reinitiation of formal consultation is required where discretionary Federal agency involvement or control over the action has been retained (or is authorized by law) and if: 1. The amount or extent of incidental take is exceeded. In instances where the amount or extent of incidental take is exceeded, any operations causing such take must cease pending reinitiation. 2. New information reveals effects of the agency action that may affect listed species or rritir.al habitat in a manner nr to an extent not rnnsirlerrcl in this npininn 3. The agency action is subsequently modified in a manner that causes an effect to the listed species or critical habitat not considered in this opinion. 4. A new species is listed or critical habitat designated that may be affected by the action. 41 CAC January 10,2013 VII-5 Staff Reports 42 of 64 Thank you for your cooperation in the effort to protect fish and wildlife resources Should you have additional questions or require clarification,please contact Jeff Howe at 772-469-4283.

Olsen Associates, Inc. 2618 Herschel Street Jacksonville,FL 32204 14 December 2012 INTRODUCTION This report presents an independent coastal engineering review of proposed dredging improvements at Wiggins Pass, Collier County, Florida, undertaken at the request of Collier County, Coastal Zone Management. The review principally focuses upon the formulation of revised inlet management strategies, alternatives analysis, and a proposed dredging project to improve navigation and beach conditions at Wiggins Pass. The project's objectives are to: 1. provide a safe navigation channel for boating 2. address erosion at Barefoot Beach (immediately north of the inlet) 3. reduce the frequency of dredging at the inlet with least(minimum) effect on the environment 4. provide a solution that is economically effective, and 5. avoid adverse impact to the Delnor Wiggins State Park(immediately south of the inlet). This review considers the engineering analysis, design, and numerical modeling -- previously conducted by Coastal Planning & Engineering, Inc. (CPE) and Humiston & Moore Engineers (H&M) over the past five years, more or less—which ultimately led to the County's selection of a proposed dredging plan for the inlet. This plan, anticipated for initial construction in 2013, consists of the following principal elements (see Figure 1), as described in the project's FDEP permit [042538-008-JC]: "The project is to straighten and expand the Wiggins Pass navigation channel by dredging a new alignment and filling the existing channel meander within the flood shoal. The dredged sand from the initial realignment will be placed in the flood shoal channel meander (Flood Shoal Disposal Area), the South Point Escarpment Repair site, the North Onshore Disposal Area and the North Nearshore Disposal Area. Any additional suitable dredge material available after those areas are filled will be placed in the Ebb Shoal Disposal Area. Approximately 7,500 cubic yards of [unsuitable] material dredged from the realigned channel ... will be placed in a separate offshore disposal area.... "Periodic maintenance dredging of the authorized navigation channel location, including the north, south and east tributary channels, may also be conducted. A projected volume of approximately 50,000 cubic yards of beach-compatible sand may be dredged during each maintenance project and placed in one or more of the authorized disposal areas, including the South Onshore Disposal Area and the South Nearshore Disposal Area. Interim maintenance dredging projects may be conducted to remove smaller amounts of sand from the channel. Based on beach and inlet monitoring surveys, the dredged material will be distributed to the disposal areas in order to balance the sediment budget between the inlet and the adjacent shorelines, offset erosion of the adjacent shorelines, and maintain the location and hydraulic stability of the navigation channel."

CAC Janaury 10,2013 VII-6 Staff Reports 3 of 31 Our "third party" review, described herein, is principally limited to the evaluation of existing, prior reports by CPE and H&M, the project's FDEP permit application file, various public correspondence and technical presentations related to the inlet and project, along with a site visit to Wiggins Pass in September 2012 followed by a brief meeting with Mr. Steve Keene (CPE) and Mr. Gary McAlpin (Collier Co.) to discuss the project objectives. This review did not include additional data collection or numerical modeling, nor reproduction of data reduction. Instead, we considered the analyses, interpretations, and conclusions presented by the prior investigators for completeness and veracity. And, in particular, we strove to compare these investigators' findings with our independent predictions of inlet dynamics and probable project performance based upon observations, experience, and engineering intuition. That is, in this review, we sought to assess the degree to which the model predictions, et cetera, reflect the probable realities of the inlet — and project performance — from the standpoint of traditional coastal engineering analysis (i.e., beyond or in lieu of numerical modeling). As such, this review presents our technical opinion regarding the appropriateness of the engineering approach, numerical modeling, interpretation of the results, recommended solutions, and project predictions. We note areas of potential concern or uncertainty, describe our expectations of probable project performance, and discuss other project alternatives or modifications that might be (or should not be) considered in the future as a function of the upcoming project's monitored performance. This includes discussion of structural versus non- structural alternatives for inlet modifications. A list of the primary documents examined for this review is presented in the "References" at the end of this report. Among these, the principal documents included Engineering Reports for inlet management studies, maintenance dredging and numerical modeling for Wiggins Pass prepared by CPE (2012, 2010, 2009), modeling and study reports by H&M (2007, 2004), and the Year- One post-construction monitoring summary of the March 2011 maintenance dredging by H&M (2012), the FDEP permit application by CPE(2010-12), among many others. VIABILITY OF THE PROPOSED APPROACH Is the proposed approach viable, relative to the project objectives? In our opinion, basically, yes; the fundamental project approach is sound, as proposed for the upcoming construction. The project intends to (1) establish a straight navigation channel from the flood shoal to across the ebb shoal to increase hydraulic flow (scour) efficiency and improve navigation, (2) initially constrain the straightened channel through temporary sand dikes that block the existing channel meander and swash (marginal) channels that wrap around the end of Barefoot Beach, and (3) place the dredged material north of the inlet, particularly closer to the inlet along Barefoot Beach (RI3-R15) and across the northern ebb shoal, toward restoring this shoreline. These principles are fundamentally sound toward establishing the project objectives. Beyond long-term performance (described below), an area of initial concern may be the viability of dredging the channel's north bank at the inlet mouth, where the channel cuts directly into the 3 olsen associates, inc. CAC Janaury 10,2013 VII-6 Staff Reports 4 of 31 south flank of Barefoot Beach, principally between channel sections C7 and 0+00 (see Figure 2, below). It seems likely that this area will shoal rapidly during construction. The dredging will require an �8 ft bank cut. This will be difficult to maintain and may ultimately lead to some draw-down and erosion of the south end of Barefoot Beach, particularly if the dredging perseveres to establish the design channel-depth template. Placement of dredge spoil along the south shoreline of Barefoot Beach should help mitigate this erosion if it has a tendency to occur; and the issue otherwise appears readily manageable during construction,through normal review. , ,,,,,,,,,,/ s§ .u, ti �� b ' �" 2a m 0.

Olsen associates, Inc. CAC Janaury 10,2013 VII-6 Staff Reports 5 of 31 PROBABLE SUCCESS OF THE PLAN How likely is the project to achieve the objectives or predictions? To answer this question we consider each of two different approaches. First, what are the physical dynamics of the existing inlet processes: that is, why are things the way they are, and are these prevailing processes inherent and ultimately unalterable by the proposed project? Second, what is the accuracy and limitation(s) of the numerical models and their likely ability to predict the project performance? Both approaches are discussed below. For purposes of clarity, the discussion is segregated among distinct topics of(a) the inlet channel and (b) the beaches — recognizing, of course, that these two features are ultimately related. INLET CHANNEL Interior Flood Shoal Meander. It appears likely, though not altogether certain, that the interior channel may have been historically straight prior to about 1953. Sometime between 1953 and 1958, the south channel was cut to Water Turkey Bay and Vanderbilt Lagoon (see Figure 3, following page.) The formation of a northward meander of the channel is evident in the 1958 image which shows a bifurcation of the flow, subsequently replaced by a mostly single channel that meanders to the inlet's interior north bank.' After 1958, basically all images and surveys indicate the strong northward meander of the inlet channel against the south inlet shore of Barefoot Beach. CPE (2012) cites a prior study which states that the dredging of the south channel increased the inlet's tidal prism by 50%. This is a plausible assertion. Inspection of aerial photographs indicates that the Water Turkey Bay/Vanderbilt Lagoon cut introduced a significant additional tidal flow to the inlet from the south (in addition to other interior waterway modifications presumably undertaken at that time). The important conclusion here is that the cutting of the south channel probably introduced a very strong change in the inlet hydraulics which (a) changed the otherwise unusually stable, nearly quasi-static configuration of this overall inlet and the adjacent shorelines, and (b) forced a northerly meander of the flood channel against Barefoot Beach. Why does the interior flood channel meander so strongly and consistently to the north? It appears to be due to (a) flow from the south channel that was cut to Water Turkey Bay/ Vanderbilt Lagoon, and (b)the influx (shoaling) of sand from the south shoreline along the State Park. Both push the interior channel toward the north, into the inlet shoreline of south Barefoot Beach/Island. Why is this important? If the inlet's flood channel was historically straight and stable in that alignment, then it is likely that re-establishing a straight flood channel would remain stable. But, if the prevailing modern configuration of the flood channel is a meander to the north—resulting from tidal flow from the south waterway at Water Turkey Bay, and from interior sand shoaling from the South Beach—then the dredged, straightened channel will tend to quickly return toward its northerly meandering orientation into the inlet's south bank shoreline of Barefoot Beach. ' A northerly meander is also evident in a 1951 photo;however,this image was 4 years after the effect of a Category 5 hurricane in 1947 which appears to have substantially altered the inlet morphology,at least temporarily. 5 .. olsen associates, inc.

Images excerpted from CPE,2012. -6 olson associates, inc. CAC Janaury 10,2013 VII-6 Staff Reports 7of31 That is, irrespective of the historical (pre-1958) conditions, the modern and prevailing condition of the inlet dynamics suggests that the interior flood channel will strive to recover its northerly meander; i.e., it will not retain its dredged, straight configuration through the inlet throat. If so, this meander will eventually defeat the hydraulic flow efficiency that is sought through the dredging of a straight inlet, and this will ultimately diminish the increased flow velocities that are sought to scour and maintain the navigation channel. Alternately stated, the interior channel may have been historically straight in the past. But that was prior to the cutting of the south channel to Water Turkey Bay (c. 1954-57) and the present configuration of the ocean shorelines — both of which force a strong and inherent northerly meander of the interior flood channel into the inlet shoreline of Barefoot Beach/Island. The historical, pre-1958 conditions no longer matter. The prevailing, modern conditions of the waterways and ocean shoreline dictate the hydraulic forces that will shape the fate of the inlet channel that is dredged today or tomorrow. The numerical modeling by CPE suggests that the tidal flows of the inlet's three interior waterways are divided as such: 29% from the north, 44% from the east, and 23% from the south. See Figure 4a. The resultant vector from these predicted flow distributions is oriented directly straight along the inlet throat. This is a favorable result in terms of possible project performance. That is, if true, it suggests that the resultant-contributory flow through the three interior waterways is directed in near perfect alignment with the proposed straight-channel cut. This would therefore promote the stability of the proposed straight, dredged channel cut. But, this result does not explain the consistent northerly meander of the interior channel observed after 1953 (beyond the sand shoaling that forms along the inlet's south bank from the south shoreline). Interestingly, if the flow from the south channel (to Water Turkey Bay) was assumed to be only 10% to 15% greater than that estimated from the CPE modeling study, then the resultant flow vector from the interior waterways would point substantially toward the north — in alignment with the northerly meander of the flood channel that has been observed since the south channel was dredged in the early 1950's. See Figure 4b. This would explain the pervasive northerly "push", or meander, of the inlet's flood channel. Unfortunately, measurements of the hydraulic flow from the three interior waterways were apparently not available for model calibration (versus singular measurement in the inlet throat); so we do not know the actual distribution of flow among these three channels. But, from aerial perspective of the substantial tidal prism that exists through Water Turkey Bay and Vanderbilt Lagoon, it is possible— or probable—that the flow velocity from the southern channel is greater than that estimated through the numerical model (i.e., equal to or greater than that shown in Figure 4b). Again, this would substantially explain the pervasive northerly meander of the flood channel in prevailing, modern conditions. In sum, in the probable case that the flow from the south channel (at Water Turkey Bay) is greater than that which is predicted by the numerical model, then the interior flood channel will seek to promptly regain its northerly meander even after the channel is dredged in a straight alignment. If so, this will act to eventually undermine the"straight-line" flow efficiencies sought by the project's dredging improvements. 7 - oisen associates, inc.

Is this shoaling from the south the principal cause of the meander? It is clearly a contributory cause, but it is also possible that the shoal itself results from the [suspected] northerly-directed flow vector that emanates from the Water Turkey Bay channel. That is, if the convergence of ebb flow at the junction of the three interior channels is biased toward the north, then one can imagine a stall in the velocity just west of the Water Turkey Bay channel, along the inlet's south bank, where sand might tend to deposit. The deposition forces the channel further north—which causes a further drop in velocity—which causes more sand to deposit on the south bank, pushing the channel further north, and so on. It is a self-perpetuating process that continues until the channel meander becomes too hydraulically inefficient, and/or until the channel can no longer migrate (due to resistance from geology, mangroves, etc.). But a key possibility is that the overall process of shoaling on the south bank is initiated by a net- northerly directed flow at the head of the inlet, near the three channels' junction. After all, it should be almost as likely that a sand shoal would form along the north bank of the inlet — caused by sand drifting in from the north beach (Barefoot Beach). But this is never observed. Hydraulic pressure from the south — which pushes against the inlet's north bank — appears to chronically prevent deposition on the north bank, and instead always favors deposition on the south bank. An alternate explanation would be that the rate of drift entering from the south is so much greater than that entering from the north, that shoaling along the south bank always pervades. But this argument seems less likely because, as described later, the overall north/south drift at the inlet appears to be fairly balanced, albeit with some net bias from the south. Outer Channel and Thalweg. The orientation of the inlet channel thalweg (deepwater "centerline") has been fairly and remarkable consistent since at least the 1960's/1970's and certainly since 1999. On the following page, Figure 5 illustrates the channel's thalweg locations traced from aerial photographs shown later in Figure 8. Figure 6 likewise illustrates (in section view) a consistent thalweg location between pre-dredging and modern conditions in 1970 and 2007, presented by H&M. This consistency demonstrates that the inlet's modern channel configuration is relatively "stable and preferred". That is, it suggests that the modern channel consistently "prefers" a particular location that is apparently ordained by prevailing coastal/hydraulic processes despite prior dredging events. This, in turn, suggests that efforts to modify this orientation may be ultimately outweighed by the prevailing natural processes. This fact is presumably already recognized; the question remains as to how fast the inlet will seek to regain this orientation. In all, this does not mean that the proposed dredging project to straighten the channel is futile, ineffective, or not recommended. Indeed, the project will likely engender improvements to the inlet consistent with the project objectives. But, this review's simplistic analysis suggests that the straightened-channel improvements will not likely be stable. That is, the channel will likely tend toward the orientations illustrated in Figure 5(following page) after dredging. - 9 _ olsen associates, inc, CAC ry 2013 -6 Janau Staff Reports 10 of 31 VII r r€E ,id sa P ' i '' u?a, r 3 7 #� 4 3. y r t s r �'�u e, # psi Es #.'iS t // f apt`g f 44fi� f 'ila 6 Figure 5–Approximate historical c, %, channel thalweg(centerline) 'T locations digitized from available �� "n Yf aerial photography.

Across the inlet mouth and ebb tidal shoal, the location of the straightened (dredge) channel is north of the modern, prevailing location. It is recognized that the location and orientation of the dredged channel is ordained by rock features at the inlet mouth and the intent to create a linear alignment with the inlet throat. 5 ' - 'fi . \ r .. :::, sr . i, ,, * > Onshore Disposal Areas x`' 04' �Jeershure Disi�usal yapy, !!

CAC Janaury 10,2013 VII-6 Staff Reports 12of31 We therefore recognize that the design channel location and azimuth are not readily altered, nor are we recommending changes at this time. Instead, this graphic (Figure 7) simply describes the fact that the location of the natural channel across the mouth and inner ebb shoal is south of the design channel location. And, to the extent that the inlet's hydrodynamics will seek to restore the existing conditions (after the channel is straightened), it may be anticipated that the outer channel might seek to drift toward the south. Alternately stated, it is anticipated that there will be substantial shoaling pressure from the north across the inlet mouth and inner ebb shoal; viz., between channel sections 0+00 and 7+00, more or less. [In fact, the Year-One post-construction monitoring results after the 2011 dredging (H&M 2012) indicate heavy shoaling from the north along the landward half of this reach.] Again, this tendency for the dredged channel to shoal from the north and migrate toward the south will occur if and when the inlet's inherent existing flow regime overrules (dominates) the modified flow regime that is created by the straightened channel. In the medium- to long-term, changing the inherent existing flow regime would require other changes to the inlet (e.g., at the interior waterways and/or at the inlet mouth, by means described at the end of this report) beyond solely straightening the channel through periodic dredging. Shorelines, Ebb Shoal and Beach Erosion. The southern 3000-ft Gulf shoreline of Barefoot Beach, north of the inlet, has exhibited erosion equating to between about -14,000 cy/yr (1992- 2009) and -10,500 cy/yr (1979-2009). Over the same time periods, the northern 3000-ft shoreline of the State Park shoreline, south of the inlet, has exhibited accretion equating to between about +6,200 cy/yr and +2,400 cy/yr. These values presumably include the effects of periodic beach fill placement. Sand dredged from Wiggins Pass and placed on the adjacent shores— including the shores beyond the 3000-ft beach areas described above -- equates to about 10,400 cy/yr to the north and 9,500 cy/yr to the south, from 1984 to 2009.2 There is a substantial offset across the inlet. The south shoreline is offset Gulfward by almost 350 feet relative to the north shoreline. This appears to be mostly modern, or recent. The offset was not strongly evident in earlier photographs (1942-1978), with the exception of an image in 1962 that is atypical [see Figure 3]. It becomes increasingly noticeable at/after 1984; and this is presumably associated with the first placements of dredge spoil to the adjacent south shoreline. Some recent aerial images of the inlet(1962-2012) are included as Figure 8, following page. One can also presume that the dredging and other changes to the interior waterways in the early 1950's changed the overall littoral regime of the inlet. That is, it is reasonable to conclude that the dredging of interior waterways and construction of upland development significantly increased the inlet's tidal prism — which, in turn, would have changed the flow patterns at the inlet mouth and led to an increase in the ebb tidal shoal volume. 3 2 These values are adapted from Tables 2 and 5,p.9 and p.18 of CPE(2012). 3 H&M(2007;p.9)describes increases in the Wiggins Pass ebb shoal volume as follows: from 0.25 Mcy in 1888 to 0.47 Mcy in 1970 to about 0.55 Mcy in 2000. -"12.- olsen associates, inc. d o 0 N N �g. 3 m.�. .� W � U> ca. bA O cc 0 N N tf) M ' N • 1 . , N%O �9 i O M At. co 0 0 0 0 c i 4 t 1 .f` O O O N M M •Ni .n .-r i N CAC Janaury 10,2013 VII-6 Staff Reports 14of31 The sand required to fulfill the larger ebb shoal volume associated with the larger tidal prism had to come from somewhere; i.e., the local littoral system. It is likely that the sand was drawn from the existing beaches by currents (and deposited to the ebb shoal rather than being recycled to the beach), and that some portion of the incident littoral drift was intercepted (and deposited to the ebb shoal rather than being passed through the inlet system). The latter, in particular, would deprive the downdrift beach of sand moreso than the updrift beach. Thus, if the net littoral drift is south-to-north, then the growth of the ebb shoal -- occasioned by the 1950's dredging of interior channels -- would be ultimately manifest as increased relative erosion along the north (downdrift) beach. This is because sand was being diverted from the beaches to "feed" the growing ebb shoal requirements that were ordained by the increased tidal prism. Most recently, the north shoal of the ebb tidal platform has eroded. CPE (2012, p. 20) indicates that the core north ebb shoal erosion is on the order of 150,000 cy (since c. 1970). Recent deflation of the ebb shoal platform where it adjoins Barefoot Beach, north of the channel, is substantial. It is visually evidenced by H&M's (2007) graphic reproduced herein in Figure 6, on prior page 10. H&M (and CPE) attributes the cause to inlet dredging and the probability that more sand should have been spoiled to the north shoreline than the south, and placed closer to the inlet—observations with which we agree. The deflation of the north ebb shoal lobe has numerous adverse effects upon the system, most of which are specifically mentioned in the reports, particularly H&M (2004, 2007). As the nearshore seabed erodes, the north shoreline is subject to increased wave attack and tidal current flow close to the beach, both of which accelerate the erosion at the south end of Barefoot Beach. And, the deeper water across the shoal allows for a broader tidal flow area-- diverting flow from the primary channel alignment. This decreases tidal velocities in the channel, which in turn, increases the likelihood of shoaling in the channel, and thereby increases dredging requirements. Restoring and/or maintaining the sand beach along the south end of Barefoot Beach will require that the northern ebb shoal lobe — or at least its platform near the shore's toe — be restored. Hence, there is great merit in depositing sand across the northern ebb shoal and blocking (reducing) the tidal current flow from the north shoreline into the inlet. The importance of both of these project elements is identified in the prior reports by H&M and CPE. The proposed plan addresses these elements to the extent that dredged sand is available from the channel- straightening project. But, as CPE notes, additional sand is required along the north beach and northern ebb shoal platform to restore the overall beach system and meet the project objectives— beyond that which is included in the proposed work to dredge and straighten the channel. Transport Direction. Based upon our review of the reports and overall inlet behavior and setting, we concur that the net overall direction of littoral drift at Wiggins Pass is from south to north. We likewise concur there is a probable net reversal (to the south, toward the inlet) along the southern 800 feet of Barefoot Beach, more or less. At the same time, we believe that the magnitude of the net [northerly] drift is probably small relative to the gross drift. That is, the northerly- and southerly-directed drift rates are probably fairly balanced, with some net overall bias to the former. This supposition is reinforced by the fact that the location of Wiggins Pass i, - oisen associates, inc. CAC Janaury 10,2013 VII-6 Staff Reports 15of31 appears to have been very stable over at least the past century, or longer. On the Gulf coast, it is not uncommon for inlets to migrate long distances in response to net littoral drift. Small stable inlets established at a location where the net drift is modest and/or mostly balanced may more readily tend to retain both their size and location. This appears to apply to Wiggins Pass. The proposed project includes an adaptive management plan by which the locations of future maintenance-dredged sand will be determined by monitoring; i.e., as a function of local needs. Clearly, the present need for sand placement is along the Barefoot Beach shoreline and north ebb shoal platform (versus the State Park beach to the south). It is reasonably anticipated that this situation will continue to be the case in the future. We concur with the importance of placing sand closer to the inlet along Barefoot Beach, and we concur with the observation that sand placed farther north in the past has provided important benefit to Barefoot Island but has not necessarily benefited the south end of the County Park shoreline near the inlet. In this specific instance, per both engineering intuition and the model results (described below), it is likely that there is not necessarily a significant adverse effect, or risk, from placing reasonable amounts of dredged sand too close to the inlet on Barefoot Beach. NUMERICAL MODELING APPROACHES Numerical modeling of Wiggins Pass was completed by both CPE (2009, 2010, 2012) and Humiston & Moore (2007). Both investigations relied upon measured tide and current data in order to calibrate their respective models. Additionally, both models simulated multiple bathymetric conditions (historical, existing, with- and without-projects). However, the general modeling scopes, approaches, and overall depth of results vary between the studies. Humiston & Moore (H&M) applied flow and wave models contained in the Coastal Modeling System (a two-dimensional U.S. Army Corps of Engineers model) to predict current fields resulting from tidal flows and incident waves under static bathymetric conditions with variable water levels. The 2007 H&M report describes the results for only two generic, frequent storm wave conditions (northwest and west). Implications for sediment transport are assumed to have been derived from the resulting current fields -- since no graphic results of sediment transport pathways are presented. The conclusions reached appear to reply much more heavily on engineering judgment than direct model results; and we note that this is a wholly acceptable and sound approach. CPE applied the Delft3D model which similarly utilizes both flow and wave models. However, Delft3D was additionally used to compute three-dimensional (3-D) flow fields and compute seabed change resulting from sediment transport (i.e., morphologic changes) under varying bathymetric conditions. The Delft3D model was principally used to predict short- and intermediate-term morphologic changes resulting from an average annual wave climate. The results were typically presented as a series of relative comparisons and used to guide the design 15- oisen associates, inc. CAC Janaury 10,2013 VII-6 Staff Reports 16of31 and permitting of the presently proposed inlet improvements. The conclusions that are presented are generally limited to descriptions of model output. CPE initially modeled approximately 8 alternative inlet design improvements. After analysis, 4 revised channel design alternatives were selected for additional modeling, including longer-term 4-year simulations for both storm and average annual wave climates. A final alternative was selected, revised, and run with and without consideration of beach nourishment placement along Barefoot Island in order to assess the likelihood of placed material reentering the navigation channel. Given the stated scopes of work and objectives presented in each of the reports, it is our opinion that while the approaches of each investigation differ, each was generally appropriate and reasonable at their respective times of preparation and publication. MODEL CALIBRATION Tidal Models. Both of the numerical flow models were calibrated against field data in order to reproduce both measured tidal elevations and currents near the inlet mouth. The H&M model was also verified utilizing a different bathymetric and oceanographic dataset, while verification of the CPE model was not completed. While the CPE model was run in 3-D mode, the calibration relied upon comparison between measured and computed depth-averaged flows. Both calibrations appear to reasonably reproduce the measured data; although CPE did not include a map of the current fields predicted for both ebb and flood tides for the calibration of existing conditions. The apparently important flows at the head of the inlet (where the three interior channels meet) are difficult to discern,and are not calibrated owing to lack of data. Wave Models. CPE calibrated the wave model against hindcast and measured offshore/onshore datasets. The modeling report suggests that achieving a sufficient calibration result required modification of the model's default parameters. Based on the data presented, the end result was a reasonably calibrated wave model. It should be noted that a separate computation domain was created for the purposes of wave model calibration. The geographic extent of this domain was later expanded to include the influence of Sanibel Island on incident waves. Due to a presumed lack of matching deepwater and nearshore data, this larger wave model was apparently not independently calibrated; and instead it relied on the calibration of the small wave domain. Calibration of the H&M wave model was not discussed in their 2007 report. H&M applied a different wave model than CPE; therefore the significance of their seeming reliance on default model parameters is not readily discernible. CPE results specifically suggest sensitivity to the consideration of bottom friction, which have the potential to negatively influence the H&M model results if this factor had not been adequately incorporated. Morphological Model. The H&M modeling effort did not include morphological modeling. The 2007 report concludes that sediment transport is predominantly directed from north-to-south in the net. This conclusion is possibly related to the limited number of wave cases simulated and - 16_ olsen associates, inc. CAC Janaury 10,2013 VII-6 Staff Reports 17 of 31 not considering sheltering effects associated with Sanibel Island. They note that net transport is likely weak in magnitude whereby the gross sediment transport is strongly bimodal in nature. CPE states that the Delft3D model was calibrated based on qualitative and subjective analysis of the model's ability to adequately predict sedimentation and erosion patterns throughout the inlet rather than predicting absolute transport volumes. It appears the volume of material shoaling the existing permitted channel cut was the only quantitative measure of model performance; and based upon the results presented, their Delft3D model was capable of shoaling the existing channel with a sediment volume consistent with measured values (viz., 28,300 cy/yr modeled versus 26,400 cy/yr measured). Calibration of the Delft3D model was completed by systematically adjusting model parameters, which is standard practice. The initial modeling report also indicates, however, that the schematized wave cases were "slightly adjusted" to facilitate model calibration (CPE, 2009 pp. 24-25). Explanation regarding the justification for, and effects of, altering the incident wave climate should have been included in the report, as alternate schematizations of offshore waves have the potential to completely transform predicted net nearshore transport processes — particularly when primarily qualitative comparisons of performance are considered. Analysis (verification) of model results dealing with volumetric losses/gains elsewhere in the model (i.e., on adjacent shorelines, interior waterways, etc.) was not presented. That is, the ability of the model to predict erosion and/or accretion along the adjacent beaches was not established. CPE (2009) presents the results of their calibrated model along with a map of measured seabed changes one year after channel dredging. These results are reproduced in Figure 9.4 CPE correctly point out that the model appears capable of predicting the following: • an ebb shoal ridge interrupting the dredged channel template, • the estimated shoaling rate within the channel template, • overall erosion along the ebb shoal around the navigation channel, • erosion along Barefoot Island, south of R-15. While the above capabilities of the calibrated model appear to be accurate, the engineering analysis does not address several questions regarding the model calibration. Most notably are the following inconsistencies between measured and predicted seabed changes south of the channel, which are within the intended spatial scope of the model: • Measured data suggest significant seabed deposition along the ebb shoal south of the channel cut. This area, however, is predicted to be heavily erosional in the model result. • The measured data show the entire ebb platform north of the channel as erosional. The model predicts that much of the north lobe of the ebb shoal is accretional. • At the south limit of the measured data, nearshore erosion occurred. This area appears to be accretional in the model result. • No measured data within the inlet throat were compared to model output— possibly due to a lack of availability of the former [i.e., note lack of data in upper graphic of Figure 9]. 4 For figures copied directly from other reports `as published'figure labels are included for easier referencing. - 17 - risen associates, inc.

Most notably, the direction of alongshore sediment transport south of the inlet differs, and the erosion potential off south Barefoot Island appears inconsistent. In any event, the results shown in Figure 10 appear to represent the `final' calibration used during production runs of the selected alternative. Based upon general comparison of the results shown in Figures 9 and 10, several observations on the model's ability to predict transport patterns are summarized as follows: Performance within the navigation channel. As mentioned, the model appears to deposit a reasonable volume of sediment into the channel annually. There is not enough information to completely understand the predicted, specific origins of shoaled material, although the transport pathways presented in the model appear physically reasonable given the limited level of detail reported. The model also suggests post-construction meandering of the navigation channel -- consistent with historical morphology -- which is physically reasonable without permanent channelization of inlet flows and/or alteration of flow emanating from the south interior channel. Channel Shoaling (modeled): o The predicted channel appears to shoal (a) with sediment which is primarily transported off Barefoot Beach, into the inlet, and subsequently mobilized west into the channel on an ebb tide; and (b) to a lesser extent the landward end of the ebb channel receives sediments derived from the southern ebb shoal platform. o There is potential for some sediment to exit the outer channel to the northwest and be transported back to Barefoot Island. Channel Shoaling (measured): o The 2012 physical monitoring report by H&M indicates the channel reaches near the inlet are shoaled hard from the north —excepting the very seaward end of the channel which shoals form the south at a lesser rate. This physical process is also identified in the 2009 CPE modeling report. The net transport vectors do predict some shoaling pressure from the north near the inlet, consistent with observations Performance north of the channel. Overall, the model appears to reasonably predict the major measured sediment transport patterns north of the channel. o The model does a good job in predicting the spatial extent of severe erosion measured along Barefoot Beach —the magnitude of this erosion, however, is not quantified or verified. o The nodal point (location of transport reversal) predicted near R-15.5 is physically reasonable and consistent with that which would be expected at the ebb shoal platform's primary attachment point to shore. o It is uncertain that the beach nearest the inlet receives much benefit from sediment which exits the channel and is mobilized towards Barefoot Island. 20- olsen associates, inc. CAC Janaury 10,2013 VII-6 Staff Reports 21 of 31 Performance south of the channel. There are several inconsistencies with the model performance (predictions) south of the channel relative to the prototype. o The predicted net littoral drift south of the inlet is directed towards the south (see Figure 10). The revised sediment budget presented by CPE (2012) contrarily indicates net sediment transport at Wiggins Pass is towards the north between R-21 and the inlet. o The model predicts that the south ebb shoal is net erosional. But, to the contrary, H&M computed a net gain of about+120,000 cy on the southern ebb shoal between 1970 and 2007 (H&M, 2007. pp.7). And, CPE notes that the south ebb shoal gained +218,000 cy from 1970 to 2011 (CPE, 2012. p 20). o All predicted sediment transport potential is directed shoreward along the south ebb shoal. This is inconsistent with statements that suggest the net transport is from south- to-north; i.e., it suggests no tendency for sediment bypassing toward Barefoot Island. That is, in Figure 10,there is no indication of net northerly transport across the inlet. o The model results give no indication that the outer ebb channel shoals from the south, the latter of which is indicated by H&M physical monitoring (2012). Summary of model performance The H&M modeling effort is much smaller in scope relative to the CPE investigations and was not directly used in identifying the selected project alternative. H&M results describe hydrodynamic but not morphological changes resulting from simulated channel dredging alternatives. Morphological modeling is considered standard practice at the present time (but was less common in 2006-07). It is our opinion that H&M incorrectly concludes net southerly directed transport at Wiggins Pass; however, we concur that it is highly likely that gross transport is strongly bimodal resulting in a comparatively low net transport magnitude. That is, the net drift is probably small and therefore difficult to discern in direction. The conclusions by H&M related to historic ebb shoal deflation and the related negative impacts to Barefoot Island are logical and consistent with coastal engineering theory. The calibrated Delft3D model developed by CPE appears to meet the stated qualitative performance objectives defined in their engineering reports. Most prominently, the model is capable of depositing a reasonable volume of sediment into the navigation channel on an average annual basis. There remain significant questions regarding the predicted sediment transport pathways which are either unclear from the model results or are contrary to either measured data and/or stated physical process at Wiggins Pass. The majority of the model's inconsistencies appear to be related to transport south of the navigation channel. CPE correctly elects to present model results in terms of relative comparisons between various project alternatives. This practice can numerically minimize the significance of smaller performance issues (i.e., potential differences in transport magnitudes away from the channel and/or numerical anomalies in transport pathways). The apparent inability of the model to predict northerly-directed transport along the State Park shoreline (consistent with CPE's published sediment budget) reduces the 21 oisen associates, inc, CAC Janaury 10,2013 VII-6 Staff Reports 22of31 believability of model results along the south beach — as well as the influence of drift from the south beach upon the channel. There is insufficient detail and/or measured data to assess the flow and transport along the flood shoal portion of the inlet — particularly in regard to the hydrodynamic role played by the three interior waterways that converge at the inlet head. PERFORMANCE OF DREDGING ALTERNATIVES The selected project alternative was not specifically modeled by H&M. The channel dredging alternatives H&M simulates are much smaller in scale relative to the selected improvements and do not include infilling of the existing channel meander. H&M concluded that the modeled channel dredging alternatives would increase the hydraulic efficiency of the inlet, but each are expected to fall short of producing a channel which will reduce maintenance requirements. H&M also predict that there is a low likelihood that channel improvements alone will significantly reduce erosion along Barefoot Island. Their findings are reasonable given the information provided in their report and relative complexity of their modeling effort. Selected Alternative. The selected alternative was modeled by CPE for both with- and without-beach fill placement along Barefoot Beach as far south as R-15.5. CPE concludes that the selected alternative is able to improve conditions at Barefoot Beach and keep the channel deeper relative to existing conditions after 4 years. Morphology. Figure 12 reproduces the initial CPE bathymetry used as model input to describe the selected alternative. Figure 13 reproduces the bathymetry after a one year model simulation. The blue circle drawn in Figure 12 denotes a near vertical channel cut located at the south end of Barefoot Island. Given that sandy sediments are modeled in this area it is physically impossible to construct this condition. Further, physical monitoring completed by H&M indicates heavy southward channel shoaling historically occurs at this location. The Delft3D model is inherently incapable of modeling the gravity-induced avalanching of channel side-slopes to a proper subaqueous angle of repose. Considering this modeling limitation, it is reasonable to conclude that under field conditions this area of the channel would immediately shoal from the north unless channel velocities were sufficient to self-scour and effectively maintain the channel cut. While the initial condition is physically unreasonable, the model appears to adapt over time by eroding the southern point of Barefoot Island and migrating the channel at the inlet throat southward (see Figure 13) --which is a physically plausible outcome. The CPE reports conclude that there will be reduced outer channel shoaling volume over time under the preferred alternative. This would be expected to occur if(a) the channel was able to self-scour, given that the project does not directly stabilize the adjacent beaches; or (b) the channel rapidly fills and reaches a state of quasi-equilibrium. If self-scouring were indicated by the modeling result, one would expect that sand entering the channel would be transported seaward by the increased ebb currents and deposited seaward of the existing ebb shoal platform— effectively elongating the ebb shoal platform over time. 22 Olsen associates, inc. ry , VII-6 CAC StaffJanau Repo10rts 2013 23 of 31 - Water �'' Depth(m) ' 0.5 -0.25 � � ktC�C�-i 7 ,...:-1.75 'r -2.5 � . - � -3.25 1 4 Ciy, " -4.75 -5.5 !1L s -8.25 1 I I I I Figure 27-Initial bathymetry-New Alternative.

CAC Janaury 10,2013 VII-6 Staff Reports 25of31 The results indicate continued erosion at the south end of Barefoot Island; however, the resultant seabed elevation is an improvement relative to existing conditions. Further, the model indicates accretion of the shoreline along Barefoot Island relative to existing conditions. CPE does not quantify the volume change along this reach; as such, it is not possible to estimate the amount of beach fill remaining in time. (This issue is discussed later, in regard to the 4-year results.) There are two areas of concern in the "one-year" result which are not fully discussed by CPE. The first is an apparent area of erosion along the northern beaches at the State Park, which is attributable to the selected alternative (Figure 14, bottom pane). In this area, the model typically predicts a depositional environment, with some minor nearshore erosion. This could suggest the relative changes represent reduced accretion -- as opposed to induced or increased erosion — relative to the existing conditions scenario. There is not enough detail to make a definitive conclusion; however, the shoreline here has been historically accretional, suggesting that this effect is reduced accretion (not erosion). After 4 years, this signal appears to diminish in both magnitude and area suggesting the likelihood of model `noise' or a temporary physical process (see Figure 15, following page). A second area of potential concern involves the predicted deflation of nearly the entire ebb shoal platform after one year -- directly attributable to the project alternative relative to existing conditions. (See the comparison of the with-project and existing conditions, Figure 14 lower pane). As previously mentioned herein, if the post-construction inlet was indeed self-scouring, one would anticipate seaward elongation of the ebb shoal over time. This would be manifest as deflation of the landward portion of the shoal and associated shoaling (accretion) along the seaward edge of the shoal. The model does indicate a small area of deposition seaward of the ebb platform, and this may reflect the effects of increased ebb currents which are moving sand further offshore because of the straight, dredged channel. Concerns over the apparent project- induced ebb platform deflation were also raised by FDEP during the project permitting process. The predicted deflation of the ebb shoal platform is not otherwise discussed or explained. Figure 15 recreates the published relative comparison of the selected alternative with existing conditions after a 4 year simulation. The model result does indicate a widening area of deposition seaward of the ebb shoal relative to the 1-year simulation. This suggests that over time, ebb currents appear to be capable of mobilizing sediment out of the channel, although the predicted erosion/sedimentation patterns for this simulation (not shown) indicate significant infilling along the seaward channel ranges. The remainder of the ebb shoal is predicted to continue deflating as a result of the project. A volumetric comparison of ebb shoal losses and gains would be educational in determining the significance, if any, of this potential impact. Interestingly, the seaward-most reaches of the navigation channel are not shaded in Figure 15. These areas indicate little to no change relative to existing conditions (see, for example, the blue- circled area in Figure 15). The location of this area relative to the design channel-dredging limits is not clear. An outline depicting the project's dredge and fill limits, superimposed upon each graphical output of the modeling results, would be useful in this regard. 25 - Eisen associates, inc. CAC Janaury 10,2013 VII-6 Staff Reports 26 of 31 The relative comparison does indicate continued benefit to Barefoot Island after 4 years. This includes the direct effects of beach fill. Without quantification of volumetric changes predicted by the model along this reach, it is difficult to accurately assess the likelihood that the fill will indeed remain in place in 4 years. A very rough guesstimate can be computed using CPE's revised sediment budget. The CPE sediment budget indicates the littoral cell covering R-14 to R-16 is expected to erode at an average annual rate of about -13,200 cy/yr (CPE, 2012). Over 4 years, this suggests a total loss of about 52,800 cy, about 105% larger than the volume of fill placed between R-12.5 and R-15.5. The margin is close enough to consider evaluating the ability of the model to mobilize (erode) a physically accurate volume of sediment along this reach. That is, the historical performance (or at least, the sediment budget) suggests that the project's fill will be depleted along Barefoot Beach after 4 years. The predicted benefit (green shading) along Barefoot Beach may otherwise suggest that the fill is retained, or the selected alternative is capable of decreasing the erosion stress in this area -- such that the longevity of the fill is increased. This outcome, of course, remains to be determined. Relative x .

Figure 15—Seabed changes attributable to the selected alternative after 4 years. d6_ olsen associates, inc. CAC Janaury 10,2013 VII-6 Staff Reports 27 of 31 Physical Performance. The CPE modeling report suggests that channel shoaling reduces over time such that the 4 year average annual rate of shoaling is about 12,800 cy/yr under existing (prior project) conditions. That is, it apparently reduces from over 26,000 cy/yr in year 1 to a very small value in years 3 and 4. This is likely due to the propensity of the outer channel cut to rapidly shoal to pre-construction conditions. The equivalent 4-year average annual rate of shoaling for the proposed project alternative is predicted be about 8,600 cy/yr5 -- a significant reduction relative to existing conditions. The predicted rapidly diminishing rate of predicted shoaling is similar to existing (prior project) measured conditions whereby the dredged outer channel shoals hard and rapidly in about one year, then slows its rate of shoaling as the channel is filled and equilibrated. At this point — which occurs within 1 or 2 years at most in existing conditions --the channel is barely navigable and requires dredging. This makes long-term (4-year) estimates of shoaling rates less meaningful in practical terms; that is, the important rate of shoaling is that which corresponds to the requisite dredging interval. The modeling indicates that this anticipated pattern of rapid shoaling —which decreases to a minimal level after 2 or 3 years -- is expected to continue with the project. This suggests the system will reach a quasi-equilibrium state. Long-term average shoaling rates are practical, if a navigable channel exists after 4 years. The Delft3D modeling suggests that after 4 years a navigable channel will remain, albeit one which is slight aligned northward of the initial cut orientation. That is,the limiting depth after 4 years under the selected alternative is deeper than - 1.75 meters (6 ft), compared with about-1 m (3.3 ft) under the existing(prior project) conditions. Based on the information provided in the modeling reports, we cannot decisively comment on the likelihood of a given magnitude of reduction in shoaling volume or the potential rate of infilling, but we concur that a more efficient channel should allow for a reduction in maintenance activity. The permit's acknowledgement of the possible need for intermittent channel dredging (up to 10,000 cy per action) between 4-year maintenance cycles appears to be a prudent measure to safeguard against uncertainty in the model results; and this should be likewise acknowledged in budget planning/operations for the Pass. Modeling results indicate that placement of beach fill north of R-15.5 will not have significant negative effect on channel performance. Based on the location of the predicted nodal point along Barefoot Beach (the point where transport is net northerly),this is likely true because most of the fill would be expected to move northward over time. It is also clear that some placed sediment will be transported back into the inlet. CPE describes this volume as insignificant. If the predicted location of the nodal point is accurate (which is probably true), this should be the case. Given that the model calibration is largely described in terms of generalities, the possibility certainly exists for differing eventualities. Nonetheless, placement of fill at and north of R-15.5 on Barefoot Beach is warranted. 5 The 2009&2012 reports suggest the selected alternative shoals at an average annual rate of 8,600 cy/yr(CPE, 2009 p 70). 27 - olsen associates, inc. CAC Janaury 10,2013 VII-6 Staff Reports 28of31 POTENTIAL ADDITIONAL MODELING EXERCISES The CPE report indicates that while the initial fill along Barefoot Island appears to offer benefit relative to existing conditions, 50,000 cy is not sufficient to mitigate the erosion which has occurred along this reach since at least the 1970's. CPE recommended continued sand placement and nourishment north of the inlet. We concur with this assessment and additionally suggest that an evaluation of shore protection structures (most probably semi-permeable groin(s)) using the Delft3D model would be of benefit. This is discussed in the section, below. The effects of some type of flow diversion dike, or similar, at the mouth of the southernmost interior waterway (to Water Turkey Bay) are of particular interest. Construction of this channel significantly altered the inlet morphology. As such, it would be prudent to investigate its effects should the proposed alternative fall short of design expectations. Additional data collection and model calibration would be required in order to reasonably model the interior hydraulics using the exiting numerical domains. This specifically includes measurement of the water flow near the mouths of the three interior waterways where they join the inlet channel, also discussed int the section, below. ALTERNATIVES(FUTURE CONSIDERATIONS) Beyond the dredge-and-fill alternatives investigated in the prior reports, consideration might be made of the following alternatives for possible future improvements to meet overall project objectives. The appropriateness of, and need for, any of these alternatives will be determined by the observed performance of the proposed project after construction. That is, implementation of any of these alternatives is not presently recommended in lieu of, or addition to, the proposed project that is anticipated for construction in 2013. 1. First and foremost, the proposed plan (c. 2013) is fundamentally viable and recommended for implementation. The project should be constructed and monitored. Any subsequent actions or modifications will be informed by the observed performance of the constructed plan. 2. It is speculated that the design location of the outer channel across the ebb shoal may be too far north [see Figure 7, page 11]. Consider means to relocate this farther south if warranted; or, perhaps, monitoring results may suggest that some curvature be introduced to the channel to follow the inlet channel's natural tendencies across the ebb shoal. 3. To the extent that it is forcing the northward meander of the flood-shoal inlet channel, consider means to modify/shunt the northward-directed flow from the south waterway (Water Turkey Bay) toward the west. Toward this end, or in any case, flow (current) measurements should be made at the mouths of the three waterways that join the inlet channel at the inlet's head. These data are needed to assess the influence that these three channels have upon the channel's morphology. [See Figures 4a and 4b, page 8.] These measurements could be made by multiple Acoustic Doppler Current Profilers (ADCP); or, more practically and economically, -28- oisen associates, inc. CAC Janaury 10,2013 VII-6 Staff Reports 29 of 31 they could be made by a single boat-mounted ADCP that traverses each mouth and the inlet throat multiple times throughout one typical spring-tide cycle.6 These measurements would be preferably repeated after a heavy rainfall, because it is likely that freshwater run-off will significantly affect the results. 4. If the straight channel adequately increases velocities and scour throughout the channel, but it is too quickly pushed back to a northerly meander across the flood shoal, then consideration might be given to hard structures (training dikes) to constrain the straight flood channel in the interior part of the inlet. A possible alternative to this action, however, could be a flow diversion structure at the mouth of the south waterway to Water Turkey Bay, noted in the prior paragraph (#3). 5. Wholesale reduction of shoaling across the ebb shoal channel, and retention of sand upon the adjacent beaches, would require semi-classical, long inlet jetties on one or both sides of the inlet. This is not a recommended alternative at this inlet given these structures' probable adverse impact upon the overall littoral system. 6. It appears that a central tenet to (1) reducing critical shoaling at the inlet mouth, and (2) reducing erosion along the south end of Barefoot Beach, is to regulate the drift of sand from the south end of Barefoot Island into the inlet mouth. Modest-scale, low-profile (or possibly permeable) beach erosion control structures may be ultimately warranted at the south end of Barefoot Beach. These might consist of a semi-permeable terminal groin at the end of the island with, perhaps, one or more weak T-head structures further updrift along the southern 800 feet of the shoreline, more or less. Detached breakwaters (in lieu of a terminal groin and/or weakly shore connected structures) are probably not recommended because of the potential for flow to develop in their lee. Again, the degree to which such coastal structures may be warranted will be determined in significant part by the observed behavior of the presently proposed inlet improvement project. 7. The utility of similar, small-scale structures at the terminal end of the south beach — toward regulating sand flow into the inlet and channel — is presently less apparent than for the north beach. It is probable that other approaches, outlined above, may be more effective in improving project performance; to be determined. 8. Finally, the need for supplemental nourishment of the Barefoot Beach shoreline (and to partly restore the ebb tidal platform on the north side of the channel) is apparent for the future; i.e., beyond those improvements and sand placements to be made by the presently proposed project. 6 We've had success with that boat-mounted ADCP approach for similar assignments at several inlet locations. -29- olsen associates, inc. CAC Janaury 10,2013 VII-6 Staff Reports 30of31 SUMMARY It is our independent opinion that the presently proposed and permitted project should be implemented at Wiggins Pass (anticipated for construction in 2013), and the performance monitored to inform future actions. The proposed project is viable and presents a reasonable likelihood of improving conditions and meeting the project objectives, relative to current practices. To the extent that the implemented project does not wholly meet expectations or predictions, it appears that the project plan may be rationally enhanced in the future by one or more modifications outlined in the preceding section. Again, the need for, or appropriateness of, these modifications will be determined by the performance of the constructed project. And, in any event, the pre-requisite for incorporating any such future modifications, if any — such as for purposes of permitting etcetera—must be the monitored performance of the fundamental project as presently proposed. Simply stated,the County needs to build this project first, and observe it. In terms of project performance and objectives, it is reasonably likely that the project will improve navigation and reduce the immediacy for dredging relative to present conditions; and it will certainly do so through avoidance and minimization of adverse environmental effect, including to the State Park. It is an economical solution, recognizing that there may be further long-term economic efficiencies to be achieved through future project enhancements— but these efficiencies, if any, cannot be affirmed until after the performance of the proposed project in 2013 is assessed. The project's probable success in mitigating erosion at Barefoot Beach is uncertain. This success will depend upon the degree to which the project can hydraulically isolate the straightened channel from Barefoot Island and reduce the tidal flow off the beach through the placement of dredged sand. The improved hydraulic efficiency of the new channel may more readily displace sand offshore, extending the ebb shoal platform further seaward, which would not improve conditions at Barefoot Beach. But, this might be offset by the project's placement of dredged sand along the south end of this beach and the associated reduction of tidal flows between the beach and the inlet. This will be determined through observation of the completed project. The extent to which the project's numerical modeling is wholly accurate is less important than it may seem. Numerical modeling is a tool that informs — but does not determine — the physical processes of a site and a proxy outcome of a considered project. Per this review, the modeling undertaken for the Wiggins Pass projects, by both prior investigators, is considered to be informative and to have been executed according to prevailing standards of practice within the limits of those data available for calibration. Assessing the probable success, and uncertainties, of such a coastal project is ultimately dependent upon the Engineer's experience and understanding of the site based upon myriad available input data. In the present instance, the consensus conclusion is that the fundamental approach of the proposed project is sufficiently valid for implementation, monitoring, and possible future enhancement as may be determined through assessment of the project's post-construction performance. 30- o'sen associates, inc.

December 14, 2012. We concur with Olsen Associates, Inc conclusions that the"...the fundamental project approach is sound,as proposed for the upcoming construction" at Wiggins Pass (December 14,2012). We also recognize there are uncertainties that will be addressed by the project monitoring plan and a flexible and dynamic maintenance plan. Some of Olsen's' largest concerns are based on nuances easily over looked.An understanding of the nuances can better explain why the specific alternatives and study methods were selected. The following points describe some of these nuances: Olsen notes that the channel cuts deep near the south point of Barefoot Beach (Station C4-C7) and could increase erosion at this point.The Florida Park Service was concerned about impacts along their interior shoreline at Delnor Wiggins Pass State Park, and the final channel alignment was modified to address their concerns. This alignment was selected to be half way between the 2010 MHW shoreline on both parks as shown in Olsen's Figure 2. Initially we proposed a western slanting transition for the Vanderbilt channel to the main channel, but eliminated it due to these concerns. The Park Service had strong support from many on the FDEP permitting staff and was a major influence on the final design.The pass has been in this alignment in the past as illustrated by the 1927 and 1970 shorelines in Figure 2 of CPE "Engineering Report" (2012). Olsen's paper spent considerable time addressing the channel migration to the north,concluding it was largely caused by the Vanderbilt Channel opening in the 1950s. A look at historic information (maps,aerial and historic shoreline locations provided in the Engineering Report(see figure 6 and Appendix B)illustrate that the channel migration and ebb shoal growth was well underway before the Vanderbilt Channel was opened. Even if the hydraulics changed significantly after the Vanderbilt Channel was opened,the speed of the northern migration is manageable, moving 100 feet between the 1970s and 2009(approximately 3 feet per year). Northern channel movement is addressed by the dynamic maintenance plan for the pass. Olsen's modeling comments describe a more comprehensive and costly effort than was contracted for by Collier County. The contracted modeling approach concentrated on showing the advantages of a straighter channel by comparing the existing plan with new plans using a model calibrated for the Gulf opening. This modeling method was selected to reduce survey, current measurements and modeling effort cost for an economical analysis. Olsen suggests that a more comprehensive modeling study is needed to better resolve the channel intersection and the beach processes. The selected methods avoided detailed measurements in the tributary channels,since the primary objectives were reducing erosion at Barefoot Beach and enhancing CAC January 10,2013 VII-7 Staff Reports 2 of 2 navigation thru the ebb channel. As indicated above, northern migration of the flood channel is expected to be only 3 feet per year and will be managed by the channel maintenance dredging program. The flood channel has been historically easier to manage. We agree with Olsen's conclusion for moving forward with construction. The cost of additional studies would be better spent in implementing the proposed project, monitoring its performance and making adjustment to the project in the future based on what is learned. This is especially true where coastal processes swing between northwest to southwest wave and climate domination on a regular basis. References: Olsen Associates, Inc.

INTRODUCTION Collier County, Florida will conduct a navigation channel dredging project in order to provide safe and navigable boating conditions within Wiggins Pass. The project is to be completed with a 14" hydraulic dredge or greater. The project will be awarded to the lowest responsive bidder with the quickest substantiated schedule. Navigation is impaired, and it is essential that dredging is completed at the fastest practical schedule. It is desired that dredging is complete within 30 to 60 days of the Notice to Proceed, before the start of sea turtle nesting season on May 1. 1.0 BASE BID. 1.1 Wiggins Pass Channel Straightening The project is to straighten and expand the Wiggins Pass navigation channel by dredging a new alignment and filling the existing channel meander within the flood shoal. Approximately 89,700 cy beach compatible sand is to be dredged from the ebb, flood and tributary channels. An additional 6,700 cy of material unsuitable for beach or nearshore placement is to be dredged as part of this project and disposed in an offshore dredge pit. All dredging will occur within the borders approved with the 2012 permit using a hydraulic dredge. Unsuitable material can be dredge with equipment selected by the CONTRACTOR. The permitted channel width ranges from 70 ft. to 240 ft. and channel depth ranges from -7.0 ft. to -12.0 ft.NAVD with a 1' overdredge allowance. Excavated compatible sand will be used to build the beach berm, nearshore, and repair scarps at Barefoot Beach. The existing channel meander will be filled as the flood shoal disposal area. Unsuitable material will be disposed of in an offshore borrow pit. The CONTRACTOR shall be thoroughly familiar with permit conditions, especially the turbidity criteria for Outstanding Florida Waters (OFW) described in the State permit. 1.2 Bid Method The lowest price responsive bid with the quickest substantiated schedule will be awarded the project's contract. The pre-bid information questionnaire must be completely filled out upon submission of your bid or your bid may not be considered. A bidder shall submit his bid on the Bid Form and Proposal furnished. All unit prices and lump sums TS-1 CAC January 10,2013 VII-8 Staff Report#2 4 of 173 shall include all expenses, overhead, profit and any other costs necessary for completing the Work. A bid without a specific method and schedule may be rejected as unresponsive. If the CONTRACTOR's schedule indicated completion by April 30, and the work is not complete, the CONTRACTOR will pay for remobilization to complete the project after sea turtle nesting season. 2.0 PROJECT MANAGEMENT. Collier County, Florida will conduct channel straightening dredging of Wiggins Pass. The project will be administered and managed by Collier County Coastal Zone Management Office. The term ENGINEER as used in these Technical Specifications will mean the Director or Inspector from this office or the project engineer with Coastal Planning & Engineering, Inc. The project team will be described at the pre-construction meeting. 3.0 ORDER OF WORK AND PROJECT SCHEDULE. As part of the bid package, the CONTRACTOR shall provide an order of work outline and project schedule to the ENGINEER and the COUNTY. The project schedule shall indicate, at a minimum, how the work will be accomplished to complete dredging in the quickest time. II. WIGGINS PASS CHANNEL STRAIGHTENING 1.0 WORK. The WORK consists of completing Wiggins Pass dredging with disposal of dredge material at the flood meander, Barefoot Beach, the nearshore disposal area or the offshore disposal site. The scope of work is listed below. The COUNTY expects construction to begin immediately after the Notice to Proceed. 1.1. The WORK consists of furnishing all labor, materials, and equipment, and performing all tasks necessary for completing the maintenance dredging of Wiggins Pass with placement of the material at Barefoot Beach and within the channel meander along the north side of the Pass. The dredging consists of the removal of approximately 89,700 cy of beach compatible material and 6,700 cy unsuitable sand, based on the 2012 survey. Material will be dredged from both the ebb shoal and flood shoal at Wiggins Pass. Pay quantities will be based on pre- and post-dredge surveys as described under TS 9.0. The dredged material will be disposed of in one of three ways; compatible sand will be used to construct beach and repair scarps at Barefoot Beach or used to fill the meander along the north shore of the Pass, unsuitable fill will be placed in an offshore disposal area. The beach and nearshore disposal areas shall be filled from north to south to the limits of the fill templates, and scarp repair will start where this ends. This fill plan may be modified based on conditions at the start of construction. All beach suitable material will be placed within the beach template, while the nearshore suitable material will be placed in the offshore template. TS-2 CAC January 10,2013 VII-8 Staff Report#2 5 of 173 1.2 The maximum pay volume shall be the bid volume unless modified by change order. The bid values do not include the over dredge volume, except for the rock area. The rock area (Station 0+00 to 5+00) shall be dredged to the over dredge depth limits, and the bid volumes reflects this condition. The dredge template may be modified using the pre-dredge survey to this volume. The estimated dredge and fill volumes are summarized below. These values do not include the 1 foot overdredge volume, except for the rock removal volume: Dredge Volumes based on 2012 Survey Compatible Sand 89,700 cy Unsuitable Rock 4,150 cy Unsuitable Material with High Peat, Clay, Silt Content 2,420 cy Total 96,270 cy Disposal Volumes based on Destination Flood Shoal Disposal Area 34,610 cy Barefoot Beach and Scarp Repair 44,740 cy Nearshore Barefoot Beach 10,350 cy Offshore Disposal in B.A. 6 Pit Rock 4,150 cy Peat, Silt and Clay 2,240 cy Total 96,270 cy 1.3 This WORK must be completed in accordance with the Plans and these specifications within the Contract Time as specified in the Contract and in strict compliance with all regulatory authorizations. These authorizations include an FDEP Consolidated Joint Coastal Permit and Sovereign Submerged Lands Authorization No. 0142538-008-JC and variance No. 0142538-013-BV, and U.S. Army Corps of Engineer's Permit No. SAJ-2004-7621 which is attached and a part of these specifications in Appendix C. Quick completion of the project is of essence, since the permits do not allow dredging after the start of sea turtle nesting season on May 1. 1.4 The CONTRACTOR shall use at least a 14" dredge capable of pumping at least 8,000 feet from the larger cuts. The dredge needs to be capable of moving some coarser sand and shell (see Appendix B). If the CONTRACTOR elects to use a larger dredge, the CONTRACTOR shall consider the existing depths in the areas to be dredged when selecting the physical plant used to execute the project. The dredge shall be suitable for the open Gulf site shown in the Plans. The CONTRACTOR and CONTRACTOR's employees shall have company experience with a 14" or larger dredge used for dredging in exposed areas similar to an ebb shoal TS-3 CAC January 10,2013 VII-8 Staff Report#2 6 of 173 channel in the Gulf of Mexico. The size of dredge shall be determined by its inside diameter at the discharge flange on the dredge pump. 1.5 The CONTRACTOR shall be solely responsible for all construction means, methods, procedures, and techniques to complete the Work in compliance with the regulatory authorizations, Plans, and these specifications including the sequence of construction as detailed in the Order of Work described in TS-3.0. 2.0 ACCESS LIMITATIONS. 2.1 Wiggins Pass project area is accessible by water from the Gulf of Mexico. The water depth through Wiggins Pass is variable due to constantly changing shoal conditions and is controlled by depth over the bar shown on the Plans. CONTRACTOR is responsible for determining the adequacy of water depth for access by floating equipment. 2.2 Ramps to launch small boats are located on the Cocohatchee River in Collier County and Cocohatchee River Park at Vanderbilt Drive and Wiggins Pass Road. The use can be coordinated at the pre-construction meeting. A ramp is also located at the Naples Landing in Naples Bay, located at the intersection of 9th Street and 11th Avenue South. A commercial loading/unloading area is located at Naples Landing. A permit to use this facility must be obtained from the Naples City Dock Master at(239)213-3070. 3.0 ORDER OF WORK AND METHODS. 3.1 To the greatest extent possible, the CONTRACTOR shall perform the work 24 hours per day, 7 days a week. The CONTRACTOR shall notify the ENGINEER if weather conditions or mechanical problems do not allow work to be conducted 24 hours per day, 7 days per week. Mechanical dredging (dragline) is limited to daylight hours. 3.2 The CONTRACTOR shall dredge the flood channel (C-3 to C-16) first, filling the flood shoal disposal (meander) area with the dredged sand. Initial material dredge from the ebb shoal channel shall be used to complete filling of the flood shoal disposal area. At least a half width ebb channel shall be established next, with suitable sand being placed on Barefoot Beach. At this point, at least a half width channel shall extend through the ebb and flood shoals, and should be extended further to Station C-23. The CONTRACTOR can dredge unsuitable material needed to achieve this channel extent (Station 15+00 to C23) at the same time. The remaining Order of Work shall proposed by the CONTRACTOR. 3.3 Construction Methods. The CONTRACTOR shall be solely responsible for all construction means, methods, procedures, and techniques to complete the Work in compliance with the regulatory authorizations, Plans, and these specifications including the sequence of construction as detailed in the Order of Work above. The following construction method is provided for information and is largely the description used for permitting. TS-4 CAC January 10,2013 VII-8 Staff Report#2 7 of 173 The initial construction will be a phased to achieve a shift in alignment while filling in the old channel. This will be achieved by dredging a pilot channel through the south side of the new flood shoal channel and depositing the material in a temporary stock pile, most likely on the flood shoal between the new and old flood channel locations (Figure 1). A portion of the north half of the new channel can be used as a temporary stockpile. The use of sheet piles to block off the old channel once the pilot channel is complete may be a method selected by the contractor. Barges can also be used to hold the stockpile. The initial dredging will be from the coarsest layer in the flood shoal. Once a significant pilot channel is completed, the stockpiled sand will be moved into the existing flood channel forming a dike with coarse sand. A dike will be constructed at two locations in the shallowest crossings in the old flood channel, at the east and west sides. The dike will be built higher than the high water level initially, to prevent overtopping and the early degradation of the dikes. Once the dike is formed, the remaining interior flood channel will be dredged, the material used to fill up the old channel between the dikes. Some of the coarse material will need to be layers over the flood shoal disposal area to mimic natural sorting that holds sediments in the flood shoal. Some subaqueous grading will be required at the end of dredging to level the dikes and rough grade the new flood shoal. The new flood shoal elevation will be -2.28 feet NAVD (MLLW), to mimic the existing shoal. It is expected that the dredged sand will occupy a larger volume when placed in the flood shoal channel, but is expected to settle with time, which can be addressed with future dredged material. In the interim, overfilling the flood shoal disposal area by 1/2 foot will mitigate for the expected settlement. Material dredged from the ebb shoal will be used to finish filling this template. Turbidity curtains will be used to protect the small seagrass patch and mangroves adjacent and north of the flood shoal disposal area. The ebb shoal dredge and fill operations will be similar to current practices. Some rubble or rocks will be dredged from the ebb shoal, but from between the two major hard (rock or rubble) substrate layers. The rock and rubble substrate that exists on either side of the proposed channel will remain untouched and continue to provide the historic lateral stability. This will maintain the channel stability by fixing the channel between the major rock substrates, which occurs already. The rock cannot be removed by dredging, but has been previously dredged using a drag line type excavator. Any unsuitable material will be disposed in an offshore borrow pit (1996 Borrow Area 6), 6 miles south of the inlet. This includes rock, rubble and silty or organic soil. Only beach compatible sand will be placed as beach disposal, and sand meeting navigation project criteria will be disposed of nearshore as described in a QA/QC plan. Most unsuitable material is located in the transition between the ebb and flood shoals. The QA/QC plan identifies the distribution of sediments by four broad categories along with their approved disposal areas. The four broad categories and disposal TS-5 CAC January 10,2013 VII-8 Staff Report#2 8 of 173 areas are old flood channel, beach disposal, nearshore and ebb shoal disposal, and disposal of unsuitable material upland or in an offshore dredge pit. Borrow Area 6 from the 1996 beach nourishment will be used for offshore disposal. Sediments will naturally redistribute within the inlet during this type of dredge operation, and therefore cleanup dredging will be the last step in initial construction. Based on the after-dredge survey by the CONTRACTOR, high spots will be identified and dredged on approval of the ENGINEER or COUNTY. Some material is expected to shoal in the south, east, and north channel entrance areas and may require dredging. The CONTRACTOR shall conduct his operations to minimize this redistribution and avoid additional dredging. The post-dredge survey will include re-surveying the cleanup areas. Any new infill occurring during construction will be treated as beach or nearshore compatible sand. Equipment. A cutterhead dredge greater than 14" will be used for major dredging of the Pass. A booster pump and a spill barge will be utilized to manage dredged material until disposal or placement. A flexible PCP pipeline will be used within the work area designated on the permit sketches and all will remain seaward of the MHW, except during beach disposal. Barges will be used to ship material to the offshore disposal site and provide temporary storage of dredged material. Barge overflow and drainage will be controlled to comply with the turbidity standards in the OFW.

TS-7 CAC January 10,2013 VII-8 Staff Report#2 10 of 173 4.0 NOTICE TO MARINERS. 4.1 CONTRACTOR shall be responsible for notifying the U.S. Coast Guard in sufficient time to allow for publication of a Local Notice to Mariners for this project. 4.2 Temporary Dredging Aids: The CONTRACTOR shall contact the U.S. Coast Guard regarding requirements for permits for all temporary buoys or dredging aid markers to be placed in the water prior to installation. The CONTRACTOR shall be .responsible for obtaining all approvals required by the Coast Guard. CONTRACTOR shall provide ENGINEER with a copy of the Coast Guard approval. Dredging aid markers and lights shall not be colored or placed in a manner that they will obstruct or be confused with navigation aids. 5.0 SOIL CONDITIONS. 5.1 All fill material placed on the beach shall be sand that is similar to that already existing at the beach site in both coloration and grain size distribution. All such fill material shall be free of construction debris, rocks, or other foreign matter and shall not contain, on average, greater than 5% fines (i.e., silt and clay) (passing the #200 sieve) and shall be free of coarse gravel or cobbles, as described in the State permits. 5.2 All fill material placed in the nearshore region shall be sand that is similar to that already existing at the beach site in both coloration and grain size distribution. All such fill material shall be free of construction debris, rocks, or other foreign matter and shall not contain, on average, greater than 10% fines (i.e., silt and clay) (passing the#200 sieve) and shall be free of coarse gravel or cobbles, as described in the State permits. 5.3 All sandy, shelly or shell material in the flood shoal with less that 5% silt will be placed in the flood shoal meander. Shelly material is natural to the flood shoal, and is essential for stability of the newly created flood shoal. The CONTRACTOR will place a layer of the coarse shelly sand on top of the emtore completed flood shoal disposal area. 5.4 The CONTRACTOR shall dispose of all materials not meeting the specifications for beach or nearshore placement in an approved offshore or upland disposal site. The material shall be surface dry during transportation by vehicular means (dump truck). The CONTRACTOR shall dispose all debris and cleared vegetation in the upland site. 5.5 See Appendix D for the State approved QA/QC plan for sediment quality. 5.6 The ENGINEER shall have the authority to determine whether the material being placed on the Spoil Sites is acceptable or unsatisfactory. However, the TS-8 CAC January 10,2013 VII-8 Staff Report#2 11 of 173 CONTRACTOR shall be responsible for assuring the quality of the placed materials. 5.7 If the ENGINEER or Collier County observes that the material being discharged into the Spoil Site is excessively silty, rocky, or otherwise unsatisfactory, the ENGINEER reserves the right to direct the CONTRACTOR to collect a sediment sample from the material discharged into the Spoil Site. Said sample shall be submitted to the ENGINEER as part of the CONTRACTOR's Daily Quality Control Report. The ENGINEER reserves the right to collect his or her own sediment samples for analysis to ensure compliance with Paragraphs 5.1 or 5.2 above. 5.8 If large quantities of rock, debris, or material exceeding the silt limit (described above) are discharged into a Spoil Site, the CONTRACTOR shall be required to cease dredging and notify the ENGINEER, providing the time, location, and source of the unsatisfactory material. The ENGINEER shall use the dredge positioning records, plans, and sand sample descriptions to determine where the CONTRACTOR may dredge to avoid additional discharge of unsatisfactory materials. 5.9 If the ENGINEER determines that the grain size and silt content of the material being discharged into a Spoil Site do not comply with these specifications, the ENGINEER reserves the right to direct the CONTRACTOR to cease dredging and remove the unsatisfactory material from the Spoil Site. Should the CONTRACTOR fail to remove the unsatisfactory material, Collier County reserves the right to remove and/or replace the unsatisfactory material, deducting the cost of such operation from the CONTRACTOR's payment. 5.10 The ebb channel and portions of the flood channel has been dredged multiple times since 1984. The major cut in the flood is new. 6.0 DREDGING. 6.1 The WORK covered by this section consists of furnishing all labor, materials, and equipment, and performing all construction stake-out, excavation, and transport of the dredged material from the areas designated to be dredged to the designated disposal areas. 6.2 Historical Artifacts: During the dredging process, should the CONTRACTOR uncover any historic artifacts of archeological and public interest, the CONTRACTOR shall notify the ENGINEER immediately. CONTRACTOR may then proceed to relocate the dredge within the approved cut area so that no additional dredging occurs within 150 feet of the area in which the artifacts were uncovered. Any and all artifacts of historic or monetary value are the property of the State of Florida. TS-9 CAC January 10,2013 VII-8 Staff Report#2 12 of 173 6.3 Trash and Debris: The CONTRACTOR shall assume the risk of any down time or expense incurred as the result of any trash or debris becoming lodged in or damaging the dredge cutterhead, suction, pump, pipe, or other equipment. 6.4 Floating Pipeline and Navigation: Floating pipelines will be marked and in compliance with U.S. Coast Guard Regulations. CONTRACTOR shall barricade both ends of floating pipelines to positively prevent personnel access. Wiggins Pass is used daily by many boaters in the area, with heavy boat traffic on weekends and holidays. It shall be the CONTRACTOR's responsibility to conduct the dredging in a manner that will allow for continuous use of the inlet by boat traffic with up to a 3 foot draft with a minimum of inconvenience to boaters. This means that the inlet cannot be blocked with pipeline, and during operation it may be necessary to either swing the dredge to the side of the cut to allow passage of boat traffic, and it may be necessary to move the dredge to allow some of the larger vessels to pass. The pipeline shall be submerged to the extent practical. 6.5 Misplaced Material: Should the CONTRACTOR, during the progress of the WORK, lose, dump, throw overboard, sink, or misplace any material, plant, machinery, or appliance, which in the opinion of the ENGINEER may be dangerous to, or obstruct navigation, the CONTRACTOR shall recover and remove the same with the utmost dispatch. The CONTRACTOR shall give immediate notice, with description and location of such obstructions, or misplaced materials, to the ENGINEER, and when required, shall mark or buoy such obstructions until the same are removed. In the event of refusal, neglect, or delay in compliance with the above requirements, such obstructions may be removed by the ENGINEER, and the cost of such removal may be deducted from any money due or to become due to the CONTRACTOR or may be recovered under the CONTRACTOR's bond. 6.6 Positioning of Dredge and Monitoring of Dredging Operations: The CONTRACTOR's dredge shall be equipped with an electronic positioning system, capable of positioning the dredge accuracies equal to +/- 3 feet horizontal and +/-0.25 feet vertical. This positioning system shall be established, operated, and maintained by the CONTRACTOR during the entire period of the project. The positioning system shall be used to precisely locate the dredge and the location of the dredge's excavation device and shall be capable of displaying and recording the dredge's location in an acceptable coordinate system which can be related to, or is directly based on, the Florida State Plane Coordinate System, East Zone, North American Datum of 1983 (FL-EAST, NAVD 88, NAD83). Navigation channel control, and shore station control, if required, will be provided to the CONTRACTOR in the same Florida State Plane Coordinate System prior to the commencement of work(Appendix E). 6.6.1 The CONTRACTOR's Daily Quality Control Report (Appendix A) provided to the ENGINEER shall include plots of the previous day's dredge locations showing the channel limits. The numbered position fixes on the daily printout and plots shall not exceed two (2) minute intervals. The location on the dredge of the master antenna and the distance and TS-10 CAC January 10,2013 VII-8 Staff Report#2 13 of 173 direction from the master antenna to the dredge's excavation device shall be reported in the Daily Quality Control Report. 6.6.2 The coordinates of the position fixes and NAVD depth of cut (X,Y,Z) for the dredge's excavation device, and the date, time, and location on the dredge of the master antenna each day, shall be also submitted to the ENGINEER in ASCII format on a CD-ROM with the Daily Contractor Quality Control Reports or sent to the County Inspector and the ENGINEER by e-mail care of Nicole Sharp, P.E. at nicole.sharp(djshawgrp.com. 6.7 CONTRACTOR's Daily Quality Control Report: The CONTRACTOR shall submit a Daily Quality Control Report. The Daily Quality Control Report with attachments shall include: • Hours of operation including all dredging start times, stop times, and description of the reason for stoppage; • The beginning and ending position stationing of the dredge and the discharge end of the dredge pipeline; • An estimate of the cubic yards of sand dredged; • All equipment and materials on the job site including the dredge, tug boats, barges, pipeline, length of pipeline in service, tractors, number of personnel on the job site; • Weather conditions; • Manatee sightings; • Dredge positioning data as described in Paragraph 6.6 above; • Sediment samples as described in Paragraph 7.6 and the QA/QC plan; • The results of turbidity monitoring as described under TS-8.2 below with a map of sampling locations; • Visits from staff of regulatory or government agencies; and • Any instructions received from regulatory agencies or ENGINEER. The Daily Quality Control Report shall be submitted by 12 noon on the day following the day for which the activity is being reported. Mobilization, progress and/or final payment to the Contractor shall be withheld until all of the required CONTRACTOR's Daily Quality Control Reports have been submitted to the Engineer. The preferred method of submittal is by e-mail. Collier County or the ENGINEER reserves the right to stop construction if the CONTRACTOR's Daily Quality Control Report is overdue. Once each week, the CONTRACTOR shall analyze a sand sample selected by the ENGINEER for laboratory testing weekly. 6.8 An acceptance section will be the area between to channel cross-section. An acceptance section will not be eligible for payment until it is dredged to the design depth. Of the rock removal are,this will be the over dredge depth. TS-11 CAC January 10,2013 VII-8 Staff Report#2 14 of 173 7.0 DREDGED MATERIAL DISPOSAL. 7.1 The WORK covered by this section consists of furnishing all labor, materials and equipment and performing all tasks necessary, including stakeout of the work, for the placement of sand on Barefoot Beach, in the nearshore region and in the flood meander region within the lines and grades shown on the Plans. 7.2 The CONTRACTOR shall establish the lines and grades of the disposal area as the WORK progresses and maintain such control as necessary to insure accurate placement of the fill. Wherever buoys or grade stakes are used within the limits of fill placement, the CONTRACTOR shall be responsible for the removal of same prior to completion of the project. The CONTRACTOR will establish and maintain visible limits of the spoil site for inspection by the ENGINEER and COUNTY. It is the CONTRACTOR's responsibility to move the location of the discharge as often as necessary to prevent accumulation of material above the maximum specified grade in the Spoil Sites. 7.3 Pursuant to TS-5.0 "Soil Conditions" above, only beach quality material with less than 5% fines is to be placed as beachfill and beach quality material with less than 10% fines is to be placed in the nearshore region. All sandy, shelly or shell material dredged from the flood shoal with less that 5% silt will be placed in the flood shoal meander. The results of previous maintenance dredging indicate that most of the material to be dredged should qualify to be placed in these disposal areas. 7.4 The maximum permissible elevations for the beach fill, the nearshore Spoil Site and the flood meaner appear on the plans. The Spoil Sites as constructed shall be no higher than these design elevations. The flood shoal disposal area can be filled up to 1/2 foot higher to mitigate expected consolidation of the sand. Further requirements for the Wiggins Pass spoil sites are described in the Specific Conditions of the FDEP Permit. 7.5 The CONTRACTOR shall be responsible for compliance with the water quality standards required by the regulatory permits. 7.6 The CONTRACTOR shall collect one 200 mg sand sample daily from the dredged discharge or spoil area and place the material in a plastic zip lock or similar bag. The CONTRACTOR shall propose the method of collection to the ENGINEER and COUNTY for their approval. The bag will be marked with time and location of sample. 7.7 The CONTRACTOR shall ensure all vessels and equipment used to transport material to the offshore disposal site are properly maintained. Material shall be secured within the vessels and shall not be allowed to have substantive leaks while in Outstanding Florida Waters or in route to the disposal site. The offshore route shall be selected to avoid nearshore hardbottom. The materials shall be maintained by the CONTRACTOR until disposal at the offshore site. No discharged water used for dredging unsuitable material shall be discharged into TS-12 CAC January 10,2013 VII-8 Staff Report#2 15 of 173 Outstanding Florida Waters (OFW). Discharge activity (pipeline) shall be at least 100 meter outside of OFW or at the offshore disposal area. Disposal or dumping into the borrow pit shall be within the target area. The CONTRACTOR shall be responsible for any material disposed of outside the limits of Borrow Area 6. Transportation of materials to the offshore disposal site shall be allowed on a 24-hr. per day basis. 7.8 The ebb shoal disposal area is to be used as a reserve disposal site for compatible material at the ENGINEER's direction. 7.9 Fill shall not cover the roots of mangroves adjacent to the flood shoal disposal area. A turbidity barrier will be placed along this edge to protect mangroves and the shallow water course to the north. 8.0 ENVIRONMENTAL PROTECTION. 8.1 The CONTRACTOR must be familiar with permit conditions for Wiggins Pass provided in Appendix C. 8.2 Turbidity 8.2.1 The CONTRACTOR's independent third party monitor, familiar with channel dredging techniques and turbidity monitoring, shall conduct all turbidity measurements. This individual shall have the authority to alter construction techniques or shut down the dredging or disposal operations if turbidity levels exceed the compliance standards established in the FDEP permit. The names and qualifications of those individuals performing these functions along with 24-hour contact information shall be submitted to the ENGINEER before the pre-construction meeting. The CONTRACTOR shall provide transportation to the monitoring locations for sampling and testing as well as for the ENGINEER and for agency staff as may be requested at any time during construction. The turbidity monitoring program contains requirements to deal with Outstanding Florida Waters (OFW) and extra measurements important to the Wiggins Pass Navigation Program. The CONTRACTOR should schedule and plan dredging to minimize turbidity. 8.2.2 The CONTRACTOR shall provide information on the location of the dredge and disposal as needed to complete the monitoring reports to the FDEP. It is the CONTRACTOR's responsibility to conduct the dredging activities so that the project remains in compliance with the FDEP water quality standards with regard to turbidity. 8.2.3 Turbidity is to be measured in Nephelometric Turbidity Units (NTUs). Outside of Outstanding Florida Waters (OFW), turbidity of more than 29 NTUs above background at the edge of the mixing zone is a violation of State Water Quality Standards. Inside of Outstanding Florida Waters TS-13 CAC January 10,2013 VII-8 Staff Report#2 16 of 173 (OFW), turbidity of more than 10 NTUs (see State permit for details) above background at the edge of the mixing zone is a violation of permit conditions. Turbidity is to be analyzed on-site as soon as possible after collection. 8.2.4 Frequency: The background and monitoring stations shall be sampled at the dredge site, beach fill site(s), and at other sites at frequencies described in the State permit. At least one set of samples shall be taken on an incoming tide each day. Sample locations: Samples shall be taken at the locations shown within the permit and at the specified distances. Daily report will be provided to the COUNTY and ENGINEER. 8.2.5 Weekly summaries of all monitoring data shall be submitted to the FDEP South District Office (Fort Myers), the COUNTY and the ENGINEER within one week of analysis with documents containing the following information: (1) permit number; (2) dates and times of sampling and analysis; (3) a statement describing the methods used in collection, handling, storage and analysis of the samples; (4) a map indicating the sampling locations; and (5) a statement by the individual responsible for implementation of the sampling program concerning the authenticity, precision, limits of detection and accuracy of the data. The ENGINEER copy shall be provided one day prior to the State copy. 8.2.6 The compliance locations shall be considered the limits of the temporary mixing zone for turbidity allowed during construction. If monitoring reveals turbidity levels greater than stated permit conditions in a visible turbidity plume or near a seagrass bed, the CONTRACTOR shall cease immediately construction activities and shall not resume until corrective measures have been taken and turbidity has returned to acceptable levels. In addition, the CONTRACTOR shall notify Collier County immediately or on the morning of the following work day if it occurs after normal work hours. 8.3 Hardbottom Communities 8.3.1 Hardbottom communities exist offshore of Collier County, near the area to be dredged and the spoil sites. The CONTRACTOR shall avoid contact with any and all hardbottom communities which are to be protected during performance of the work and in mobilization and demobilization to and from the project site. The Plans reflect the location of hardbottom in the general project area for the convenience of the CONTRACTOR. However, the CONTRACTOR SHALL NOT depend solely on the mapped hardbottom shown on the Plans. It will be the responsibility of the CONTRACTOR to utilize any other means to ensure that there are no hardbottom formations where the CONTRACTOR elects to place pipes, spuds, anchors, cables, drag arms or any other objects on the bottom. The CONTRACTOR shall use all means necessary to prevent impacts to the TS-14 CAC January 10,2013 VII-8 Staff Report#2 17 of 173 hardbottom. It will be solely the responsibility of the CONTRACTOR to avoid all hardbottom formations and hardbottom biological communities. 8.3.2 ENCROACHMENT ON, OR CONTACT WITH, HARDBOTTOM COMMUNITIES BY ANCHORS, CABLES, PIPES, SPUDS, DRAG ARMS, CUTTERHEAD OR ANY OTHER DREDGE EQUIPMENT IS STRICTLY PROHIBITED. The CONTRACTOR shall take note that the State of Florida has levied significant fines to dredge contractors who have damaged protected hardbottom communities. The CONTRACTOR shall be responsible for any and all fines, or legal expenses, or hardbottom repairs or mitigation requirements incurred by the CONTRACTOR, Collier County, and the ENGINEER in the event that the CONTRACTOR has damaged hardbottom communities in the project area. 8.3.3 At no time shall the CONTRACTOR be permitted to lay cables or pipe or any other object on any hardbottom resources, or within 75 feet of the hardbottom resources. Additionally, pipes transporting sediment to the Spoil Sites shall be maintained without leaks to avoid spreading sediment over the bottom. Any leaks shall be promptly repaired before pumping operations may continue. The CONTRACTOR shall also exercise caution in operating all vessels in shallow water. 8.3.4 The CONTRACTOR shall make every effort to avoid the placement of pipeline on existing hardbottom. Measures shall be taken to adequately prevent damage to hardbottom by movement of the pipeline. It is the CONTRACTOR's responsibility to ensure that the pipeline is not placed on hardbottom areas. 8.3.5 Mobilization, demobilization and transport to, and from, the project site and offshore disposal area will be controlled by the CONTRACTOR to avoid contact with any and all hardbottom formations. AVOIDANCE OF DAMAGE TO HARDBOTTOMS IS THE RESPONSIBILITY OF THE CONTRACTOR. 8.3.6 No cables, equipment or other objects shall hang over the side of the dredge, any barges or tugs, or any other vessels, floating pipelines, pontoons or floating equipment. There shall be no anchoring of the dredge or any attendant equipment (vessels, barges, etc.) outside of the limits of the area to be dredged. These measures are required to avoid hardbottom damage from sagging cables or other objects. 8.4 Seagrass Protection 8.4.1 Seagrass communities exist near the areas to be dredged. The CONTRACTOR shall avoid contact with any and all seagrass communities. The Plans reflect the location of seagrasses in the general project area inside the inlet for the convenience of the CONTRACTOR. However, the CONTRACTOR SHALL NOT depend solely on the TS-15 CAC January 10,2013 VII-8 Staff Report#2 18 of 173 seagrasses locations shown on the Plans. It will be the responsibility of the CONTRACTOR to utilize divers or observers and/or any other means to ensure that there are no seagrasses where the CONTRACTOR elects to place pipes, spuds, anchors, cables, drag arms or any other objects on the bottom. The CONTRACTOR shall use all means necessary to prevent impacts to the seagrasses. It will be solely the responsibility of the CONTRACTOR to avoid all seagrass areas. Mangroves also exist further inside the inlet, and should be given similar protection. 8.4.2 ENCROACHMENT ON, OR CONTACT WITH, SEAGRASSES IS STRICTLY PROHIBITED. The CONTRACTOR is responsible to utilize his/her own resources to identify and avoid contact with or damage to seagrass areas. At no time shall the CONTRACTOR be permitted to excavate, place fill on, traverse in any way, or place or store any equipment or material on any seagrass resources. Pipeline shall be floated across all areas containing seagrasses. The CONTRACTOR shall take note that the State of Florida has levied significant fines to contractors who have damaged seagrass communities. The CONTRACTOR shall be responsible for any and all fines, or legal expenses, or repairs or mitigation requirements incurred by the CONTRACTOR, Collier County, and the ENGINEER in the event that the CONTRACTOR has damaged seagrass communities. 8.4.3 If living seagrass is found in the area to be dredged or the Spoil Site, the CONTRACTOR shall inform the ENGINEER, who will direct the CONTRACTOR on whether or how to continue with the excavation. 8.4.4 Seagrasses are susceptible to damage caused by turbidity. The CONTRACTOR shall make every effort to avoid increasing the turbidity level as a result of the dredging activities, including the provisions in Section 8.2, "Turbidity". The CONTRACTOR is to follow all requirements concerning water quality as provided by permits for the project. In the event of a turbidity violation or high turbidity levels as observed by the ENGINEER, Collier County, or agency representatives, the CONTRACTOR shall cease construction and take immediate corrective action. The corrective action shall comply with the project permits as well as the direction of the ENGINEER and Collier County. All turbidity testing and other measures shall be performed by the CONTRACTOR at his or her own expense. 8.5 Shorebirds 8.5.1 Shorebirds are protected by State and Federal laws; required protection measures are provided in the State permit and FWS BO's. The shorebird monitoring will be a subcontractor of the COUNTY, but the CONTRACTOR has responsibilities. There are three (3) categories of shorebirds addressed in the permits and biological opinions, and the following is provided to clarify their inter-relationship. TS-16 CAC January 10,2013 VII-8 Staff Report#2 19 of 173 8.5.2 Endangered or Threatened Species. Section 9 of the Act and Federal regulation pursuant to section 4(d) of the Act prohibit the take of endangered or threatened species without special exemption. Take is defined as to harass, harm, pursue, hunt, shoot, wound, kill, trap, capture or collect, or to attempt to engage in any such conduct. Harm is further defined by the Service to include significant habitat modification or degradation that results in death or injury to listed species by significantly impairing essential behavioral patterns, including breeding, feeding, or sheltering. Harass is defined by the Service as intentional or negligent actions that create the likelihood of injury to listed species to such an extent as to significantly disrupt normal behavior patterns which include, but are not limited to, breeding, feeding, or sheltering. Incidental take is defined as take that is incidental to, and not the purpose of, carrying out an otherwise lawful activity. 8.5.3 The Migratory Bird Treaty Act. The MBTA implements various treaties and conventions between the U.S., Canada, Japan, Mexico, and the former Soviet Union for the protection of migratory birds. Under the provisions of the MBTA, it is unlawful "by any means or manner to pursue, hunt, take, capture or kill any migratory bird except as permitted by regulations issued by the Service. The term "take" is not defined in the MBTA, but the Service has defined it by regulation to mean to pursue, hunt, shoot, wound, kill, trap, capture or collect any migratory bird, or any part, nest or egg or any migratory bird covered by the conventions or to attempt those activities. 8.5.4. Breeding Shorebirds. For nesting seabird and shorebird, breeding is confirmed by the presence of a scrape, eggs, or young shorebirds, exhibiting breeding behavior, shorebird/seabird chicks, or shorebird/seabird juveniles as outlined in the FSD Breeding Bird Protocol for Shorebirds and Seabirds. Breeding is not considered to be completed until all chicks have fledged. 8.5.5. The remainder of birds are undesignated for the purpose or the permits. There are some actions that can be used to manage shorebirds interference with the project. Normal construction activity may keep shorebirds out of the construction area. MBTA and undesignated shorebirds can be shooed away. The tides are a way to move shorebirds from the construction area. Sand placed in the nearshore zone can avoid shorebird restriction, which must be approved by the ENGINEER. The primary sources of shorebird conditions for a clear understanding of what is allowed are the permits and biological opinions. 9.0 SURVEYS. 9.1 Pre-dredge and Post-Construction Surveys: The CONTRACTOR will conduct a pre-dredge and post-construction survey of the project area and the cost will be TS-17 CAC January 10,2013 VII-8 Staff Report#2 20 of 173 paid 40% for completion and acceptance of the pre-construction survey and the remainder on completion and acceptance of the post-construction survey. The results of the pre-construction survey will be used to update the dredge volume and identify any new regions requiring dredging. Generally, the survey cross- sections are at 100 foot intervals, and they will be surveyed not only across the defined navigation channel but also extend out to the lateral limits defined in the plan and cross-section views shown in the Physical Monitoring Plan in Appendix D. The post-construction survey will include at least the same region surveyed pre-construction, in addition to the following: i) A center line survey between Stations C28 and 15+00, which will cross the rock dredge area between Stations 0+00 and 4+00. ii) Cross-section at Station 2+50 iii) A post-use survey of B.A. 6 at 200 foot spacing and extending 200 feet outside the borrow area limits. The CONTRACTOR can use the post-construction survey as the pay survey or conduct the two surveys separately. The post-construction survey shall be completed after all the work is complete. The spoil sites shall be surveyed pre- and post-construction at the R-monuments specified above and in the Physical Monitoring Plan and at the mid-point between monuments. The surveys will extend 2,000 feet offshore. The same lines must be surveyed pre-and post-construction. A pre- and post-construction contour map of the entire project area will be developed by the CONTRACTOR and it will be placed on top of a recent aerial photograph with labeled R-monument and cross-section locations. The ENGINEER can provide a CAD file. 9.2 Acceptance (Pay) Surveys: To be eligible for payment under PROGRESS PAYMENTS of the CONSTRUCTION AGREEMENT, the CONTRACTOR shall perform an acceptance survey prior to payment for an acceptance section. The CONTRACTOR shall notify the ENGINEER at least 24 hours prior to conducting a survey. At the option of the ENGINEER, the survey shall be performed under the observation of the ENGINEER. All surveys shall be performed in accordance with the paragraphs below: 9.2.1 Acceptance surveys shall be scheduled so that field notes and computations can be furnished to the ENGINEER. If the ENGINEER's first review of the survey data shows that additional survey work is required in an area to conform to the standards below, the CONTRACTOR shall take additional elevations and/or soundings where the additional survey work is required. The CONTRACTOR shall take elevations and soundings until the ENGINEER deems the survey in such area to be in compliance with these specifications. TS-18 CAC January 10,2013 VII-8 Staff Report#2 21 of 173 9.2.2 Acceptance surveys shall cover, as a minimum, the area surveyed during the Pre-dredge Survey. The CONTRACTOR shall survey along the same lines surveyed during the Pre-dredge Survey. The acceptance survey may count as the post-construction survey in consultation with the ENGINEER, if conditions have not changed significantly during construction. 9.2.3 During all acceptance surveys, elevations and soundings shall be taken along each survey line at intervals-of no more than 25 feet and at all break points. 9.2.4 Hydrographic survey profiles shall be conducted by the CONTRACTOR using standard electronic positioning and hydrographic surveying equipment and techniques. The CONTRACTOR shall utilize electronic positioning equipment which has a minimum accuracy of 3 feet horizontal. The CONTRACTOR shall utilize an .Innerspace Model 448 thermal depth sounder recorder or equivalent. The CONTRACTOR shall use measured tides to correct depth soundings. 9.2.5 The CONTRACTOR shall maintain complete and accurate field notes, sketches, recordings and computations required in establishing the necessary horizontal and vertical control. All survey data shall be recorded in accordance with accepted standards and as approved by the ENGINEER. All the above data shall be available at all times during the progress of the work for ready examination and use by the ENGINEER. Upon request of the ENGINEER, the CONTRACTOR shall furnish a copy of above survey data. In addition to printed and handwritten survey data specified in this paragraph, the CONTRACTOR shall record his survey data in the following electronic, ASCII (plain text), comma delimited format: Col.-1 Col.-2 Col.-3 Col.-4 Easting (feet), Northing (feet), Elevation (feet), CL Station or Profile Line The easting and northing values must be referenced to the Florida State Plane Coordinate System, East Zone, and NAD 83. Elevation values must be referenced to the vertical datum appearing on the plans. Data referenced to any other horizontal or vertical datum will be rejected by the ENGINEER and returned to the CONTRACTOR for revision. Data must be in ASCII (plain text), comma delimited format. Data submitted in any other electronic format will be rejected by the ENGINEER and returned to the CONTRACTOR for revision. Data shall be submitted to ENGINEER on CD-ROM or e-mailed to the ENGINEER care of: TS-19 CAC January 10,2013 VII-8 Staff Report#2 22 of 173 Nicole Sharp, P.E. Coastal Planning&Engineering, Inc. nicole.sharp(Zi)shawgrp.com The CONTRACTOR shall not be paid for dredging without submission of survey data for the acceptance section from which the material was dredged. The survey information will be used by the ENGINEER to control and make adjustments to the volume of beach fill placed along the beach. 9.2.6 The data collected by the surveys shall be reviewed, signed, and sealed by a Professional Surveyor and Mapper (PSM) registered in the State of Florida,to FDEP standards. 9.3 The ENGINEER and Collier County reserve the right to make such surveys as necessary for verification of surveys made by the CONTRACTOR. 9.4 In addition to the above requirements, the CONTRACTOR shall compute the amount of fill removed based on the pre-construction (Pre-dredge Survey) and the CONTRACTOR's acceptance surveys using the average end-area method. The ENGINEER reserves the right to independently estimate the amount of material removed from the new channel based on the Pre-Construction Survey, the CONTRACTOR's acceptance surveys, or any before- or after-dredge surveys performed by the ENGINEER or Collier County. Where cross-sections overlap each other or where large curves exist in the channel, adjustments to compensation will be made to eliminate or avoid double counting or to correct for geometry. This will be a topic at the pre-construction meeting. If there are substantial conflicts or differences between the CONTRACTOR's estimate and the ENGINEER's estimate,the amount paid to the CONTRACTOR by the Owner shall be based on the ENGINEER's estimate. 9.5 In all cases, payment shall be governed by the paragraphs below, "Overdepth and Side Slopes" and "Measurement and Payment". Paper plots of the survey profiles along with computations shall be furnished to the ENGINEER. 9.6 Overdepth and Side Slopes: Overdepth dredging is NOT permitted under the current permits in some areas, is noted on the plans where it applies. The CONTRACTOR shall take care to avoid dredging beyond the designated overdepth appearing in the plans. Material taken from beyond the designated overdepth appearing in the plans: (a)will be considered a violation of the permits, (b)will be deducted from the total amount dredged as excessive dredging, and (c) will not be paid for. Material actually removed within the limits shown on the plans, leaving final side-slopes no flatter than 1 vertical to 4 horizontal for Wiggins Pass will be paid for, whether accomplished by dredging the original position or the space below TS-20 CAC January 10,2013 VII-8 Staff Report#2 23 of 173 the pay slope plane and allowing up slope materials to fall into the cut. If any material is removed from below the designated overdepth, or outside of the indicated side-slopes, the volume of such material will be deducted from the amount paid to the CONTRACTOR. The maximum pay volume is the amount shown on the bid form,although overdepth tolerance is provided. 9.7 Measurement and Payment: The total volume of all material removed and to be paid for under this contract for the bid item "Dredging and Disposal of Beach and Nearshore Compatible Sand" will be measured by the cubic yards removed from the navigation channels, by computing the volume between the bottom surface as shown by the Pre-Construction Survey and the bottom surface as shown by the CONTRACTOR's acceptance surveys. Volumes shall be calculated using the average end-area method with adjustments for channel geometry and overlap. The calculations will exclude any volume of material. (a) removed from beyond the limits of the side-slopes, (b) removed from below the allowable design depth, (c) misplaced, or; (d) removed from areas not surveyed by the CONTRACTOR. All pay quantities shall be determined based on the pre-construction surveys and the after-dredging surveys conducted by the CONTRACTOR, ENGINEER, or Collier County. 9.8 The maximum pay volume is the amount shown on the bid form, unless modified by change order. Acceptance will be based on full dredging of the cross-section down to the design cut, except in the rock area vicinity (Station 0+00 to 5+00), where dredging the overdepth region is essential. If changes to the cross-sections are needed to match bid volume to current conditions, they will be made at the pre-construction meeting. 10.0 MOBILIZATION AND DEMOBILIZATION. 10.1 All costs connected with the mobilization and demobilization of all the CONTRACTOR's plant and equipment, including dredge plant and equipment, if used, will be paid for at the contract lump sum price for this item. Sixty percent (60%) of the lump sum price will be paid to the CONTRACTOR after commencement of dredging and placement of a quantity of, at minimum, one thousand (1,000) cubic yards of material in a twenty-four (24) hour period (or less time). The CONTRACTOR's survey records will be used to demonstrate the volume placed and the ENGINEER, at his discretion, may verify the survey results. 10.2 The remaining forty percent(40%) will be included in the final payment for work under this Contract. In the event the ENGINEER considers that the amount in this item, which represents mobilization, does not bear a reasonable relation to the cost of the work in this contract, the ENGINEER may require the CONTRACTOR to produce cost data to justify this portion of the bid. Failure to TS-21 CAC January 10,2013 VII-8 Staff Report#2 24 of 173 justify such price to the satisfaction of the ENGINEER will result in payment of actual mobilization costs, as determined by the ENGINEER at the completion of mobilization, and payment of the remainder of this item in the final payment under this Contract. III. ENVIRONMENTAL PROTECTION 1.0. ENVIRONMENTAL PROTECTION. 1.1 For the purpose of this specification, environmental protection is defined as the retention of the environment in its natural state to the extent possible during project construction and to enhance the natural appearance in its final condition. Environmental protection requires consideration of air, water, and land, and involves noise, solid waste management as well as other pollutants. In order to prevent any environmental pollution arising from the construction activities in the performance of this Contract, the CONTRACTOR and his Subcontractors shall comply with all applicable Federal, State and local laws and regulations concerning environmental pollution control and abatement. 1.2 The CONTRACTOR must be familiar with permit conditions for Wiggins Pass dredging. Not all permit conditions are explicitly stated within the Technical Specifications, but can be found within the permits in Appendix C. 1.3 Subcontractors: Compliance with the provisions of this section by the Subcontractors will be the responsibility of the CONTRACTOR. 1.4 Prevention of Landscape Defacement. 1.4.1 The CONTRACTOR shall not deface, injure, or destroy dune vegetation, trees or shrubs, nor remove or cut them without the authority of the ENGINEER. Ropes, cables, or guys shall not be fastened to or attached to any existing nearby trees or existing structures. Where the possibility exists that trees may be defaced, bruised, injured, or otherwise damaged by the CONTRACTOR's equipment or operations, the CONTRACTOR shall adequately protect such trees. Monuments and markers shall be protected before construction operations commence. 1.4.2 Restoration of Landscape Damage. Any trees, beach vegetation, or other landscape feature scarred or damaged by the CONTRACTOR's equipment or operations shall be restored to a condition satisfactory to the ENGINEER. Experienced workmen shall perform restoration of scarred and damaged trees in an approved manner. Trees damaged beyond restoration shall be removed and disposed of by CONTRACTOR in a manner approved by ENGINEER. Trees that are to be removed because of damage shall be replaced at the CONTRACTOR's expense by nursery- grown trees of the same species or a species approved by the ENGINEER. TS-22 CAC January 10,2013 VII-8 Staff Report#2 25 of 173 The ENGINEER shall also approve the size and quality of nursery-grown trees. 1.4.3 Any upland storage areas required by the CONTRACTOR shall be the responsibility of the CONTRACTOR, and the CONTRACTOR shall obtain all necessary approvals for any such areas. 1.5 Post-Construction Cleanup or Obliteration: The CONTRACTOR shall obliterate all signs of construction Work areas, waste materials, or any other vestiges of construction, including grade stakes, as directed by ENGINEER. The area will be restored to near natural conditions. 1.6 Spillage: Special measures shall be taken by the CONTRACTOR to prevent bilge pumpage or effluent, chemicals, fuels, oils, greases, bituminous materials, waste washing, herbicides and insecticides from entering public waters. 1.7 Disposal: Disposal of any materials, wastes, effluent, trash, garbage, oil, grease, chemicals, etc., in areas adjacent to streams or other waters of the State shall not be permitted. If any waste materials are dumped in unauthorized areas, the CONTRACTOR shall remove the material(s) and restore the area(s) to the original condition. If necessary, contaminated ground shall be excavated, disposed of as directed by ENGINEER, and replaced with suitable fill material, compacted and finished with a suitable and compatible top layer of material and planted as required to reestablish vegetation. 1.8 Additional Costs: No separate payment will be made for the prevention, control, or abatement of environmental pollution, and all costs in connection therewith or incidental thereto shall be included in the applicable unit price per cubic yard for dredging. 1.9 Manatees 1.9.1 In order to ensure that manatees are not adversely affected by the construction activities as described in these specifications, the State FDEP permit requires the following: 1.9.1.1 All vessels associated with the project will be required to operate at "no wake" speeds at all times while in waters where the draft of the vessel provides less than four feet of clearance from the bottom. All vessels shall follow routes of deep water whenever possible. 1.9.1.2 The CONTRACTOR shall instruct all personnel associated with the project of the potential presence of manatees and the need to avoid collisions with the manatees. CONTRACTOR shall be responsible for all construction personnel to observe water- related activities for the presence of manatees, and shall TS-23 CAC January 10,2013 VII-8 Staff Report#2 26 of 173 implement appropriate precautions to ensure protection of manatees. 1.9.1.3 CONTRACTOR shall advise all construction personnel that there are civil and criminal penalties for harming, harassing, or killing manatees that are protected under the Marine Mammal Protection Act of 1972, the Endangered Species Act of 1973, and the Florida Manatee Sanctuary Act. The CONTRACTOR will be held responsible for any manatee harmed, harassed, or killed as a result of construction of the Project. 1.9.1.4 Prior to commencement of construction of the Project, the CONTRACTOR shall construct and display temporary signs concerning manatees. 1.9.1.4.1 For vessels, CONTRACTOR shall place a temporary sign measuring at least 8.5" X 11" reading "Manatee Habitat/Idle Speed in Construction Area" in a prominent location visible to employees operating the vessels. 1.9.1.4.2 In the absence of a vessel, CONTRACTOR shall place a temporary sign at least 2' X 2' reading "Warning: Manatee Habitat" in a location prominently visible to land based, water-related construction crews. 1.9.1.4.3 CONTRACTOR shall place a second temporary sign at least 8 1/2" X 11" reading "Warning: Manatee Habitat. Operation of any equipment closer than 50 feet to a manatee shall necessitate immediate shutdown of that equipment. Any collision with and/or injury to a manatee shall be reported immediately to the Florida Marine Patrol at (800) DIAL-FMP or (800) 342-5367". A sign measuring at least 3 ft. by 4 ft. that reads "Caution Manatee Area" will be posted if vessels are associated with the construction, and should be placed visible to the vessel operator. 1.9.1.5 Siltation barriers, if used, shall be made of material in which manatees cannot become entangled, are properly secured, and are regularly monitored to avoid manatee entrapment. Barriers must not block manatee entry to or exit from essential habitat. 1.9.1.6 If manatees are seen within 100 yards of the active daily construction/dredging operation, CONTRACTOR shall ensure that all appropriate precautions shall be implemented to ensure TS-24 CAC January 10,2013 VII-8 Staff Report#2 27 of 173 protection of the manatee. These precautions shall include the operation of all moving equipment no closer than 50 feet of a manatee. CONTRACTOR is advised that operation of any equipment closer than 50 feet to a manatee shall necessitate immediate shutdown of that equipment. 1.9.1.7 CONTRACTOR shall report any collision with and/or injury to a manatee immediately to the Florida Marine Patrol (800) DIAL-FMP, or (800) 342-5367, and to the Florida Bureau of Protected Species Management at(904) 922-4330. 1.10 Marine Turtle Nesting Protection 1.10.1 To facilitate turtle monitoring by Collier County, the CONTRACTOR shall provide a copy his construction schedule and all updates of that schedule to the Collier County Turtle Program through the Coastal Zone Management Department. 1.10.2 From April 1 through November 30, all project lighting shall be limited to the immediate area of active construction only and shall be the minimal lighting necessary to comply with U.S. Coast Guard and/or OSHA requirements. Stationary lighting on the beach and all lighting on the dredge shall be minimized through reduction, shielding, lowering, and appropriate placement of lights to minimize illumination of the nesting beach and water. 1.10.3 Upon locating a dead, injured, or sick endangered or threatened sea turtle specimen, initial notification must be made to Collier County Environmental Services at (239) 890-6486, and then to the FWC at (888) 404-FWCC. Care should be taken in handling sick or injured specimens to ensure effective treatment and care and in handling dead specimens to preserve biological materials in the best possible state for later analysis of cause of death. In conjunction with the care of sick or injured endangered or threatened species or preservation of biological materials from a dead animal, the finder has the responsibility to ensure that evidence intrinsic to the specimen is not unnecessarily disturbed. 1.10.4 No construction, operation, transportation or storage of equipment or material are authorized for beach or nearshore placement during marine turtle nesting season (May 1 to October 31). 1.11 Seagrass and hardbottom locations are provided in a map in the Plans. 2.0 FINAL CLEANUP. 2.1 Final clean-up shall include the removal of all the CONTRACTOR's plant and equipment either for disposal or reuse. Plant and equipment to be disposed of TS-25 CAC January 10,2013 VII-8 Staff Report#2 28 of 173 shall only be disposed of in a manner and at locations approved by the ENGINEER. 2.2 Unless otherwise approved in writing by the ENGINEER, the CONTRACTOR will not be permitted to abandon any equipment in the disposal area for dredged materials, pipeline access areas, beach fill areas, or other areas adjacent to the Work site. 3.0 RESTRICTION OF ACCESS BY THE PUBLIC. 3.1 CONTRACTOR shall erect such barricades, fences and signs as necessary to prevent public access to the construction area around the pipeline discharge. CONTRACTOR shall also be responsible to post appropriate warnings within the construction area and within the water to prevent pedestrians from swimming within an area affected by the construction project. It will be the CONTRACTOR's responsibility to insure that the construction project area is sufficiently posted and monitored to prevent swimmers, boaters, and pedestrians from injury from the construction. The disposal area is adjacent to beach used for recreation during all seasons of the year.

Tamiami Trail Naples, FL 34112 Project Name: Wiggins Pass Navigation Channel Expansion and Maintenance AGENT: County: Collier Stephen Keehn Coastal Planning and Engineering, Inc. Issuance Date: XX 2481 NW Boca Raton Blvd. Boca Raton, FL 33431 Expiration Date: XX [Ten Years After Permit Issuance] REGULATORY AUTHORIZATION: This permit is issued under the authority of Chapter 161 and Part IV of Chapter 373, Florida Statutes(F.S.), and Title 62, Florida Administrative Code (F.A.C.). Pursuant to Operating Agreements executed between the Department of Environmental Protection (Department) and the water management districts, as referenced in Chapter 62-113, F.A.C., the Department is responsible for reviewing and taking final agency action on this activity. PROJECT DESCRIPTION: The project is to straighten and expand the Wiggins Pass navigation channel by dredging a new alignment and filling the existing channel meander within the flood shoal. The dredged sand from the initial realignment will be placed in the flood shoal channel meander(Flood Shoal Disposal Area), the South Point Escarpment Repair site, the North Onshore Disposal Area and the North Nearshore Disposal Area. Any additional suitable dredge material available after those areas are filled will be placed in the Ebb Shoal Disposal Area. Approximately 7,500 cubic yards of material dredged from the realigned channel is not environmentally suitable for beach, nearshore or inlet disposal; so this material will be placed in a separate offshore disposal area (excavated basin of Borrow Area 6, from the 1996 Collier County beach restoration project). Periodic maintenance dredging of the authorized navigation channel location, including the north, south and east tributary channels, may also be conducted. A projected volume of approximately 50,000 cubic yards of beach-compatible sand may be dredged during each maintenance project and placed in one or more of the authorized disposal areas, including the CAC January 10,2013 VII-8 Staff Report#2 86 of 173 Draft Joint Coastal Permit Wiggins Pass Navigation Channel Expansion and Maintenance Permit No. 0142538-008-JC Page 2 of 26 South Onshore Disposal Area and the South Nearshore Disposal Area. Interim maintenance dredging projects may be conducted to remove smaller amounts of sand from the channel. Based on beach and inlet monitoring surveys, the dredged material will be distributed to the disposal areas in order to balance the sediment budget between the inlet and the adjacent shorelines, offset erosion of the adjacent shorelines, and maintain the location and hydraulic stability of the navigation channel. The proposed variance (File No. 0142538-013-BV) from Rule 62-4.244(5)(c), F.A.C., would temporarily establish expanded mixing zones at the dredging sites that extend 300 meters downcurrent from the turbidity source, or to the edge of the nearest seagrass bed, whichever is closer. The requested variance from the anti-degradation provisions in Rule 62-4.242(2)(a)2.b., F.A.C.,would establish a maximum allowable turbidity level of 10 NTUs above background for work within OFW. PROJECT LOCATION: The dredge sites are located within Wiggins Pass, South Channel and the Gulf of Mexico. The nearshore and beach disposal sites are located north of the inlet, between DEP Reference monuments R-12 to R-15.5, and south of the inlet, between R-18 and R-20. The ebb shoal disposal area is located offshore of Wiggins Pass, approximately 300-1000 feet north of the authorized inlet channel. The South Point Escarpment Repair site is located on the beach, at the southern end of Barefoot Beach Preserve. The Flood Shoal Disposal Area is a portion of the meandered channel, located within Wiggins Pass, on the northern side of the new channel. The entire project is located in Collier County, Sections 17 and 20, Township 48 South, Range 25 East, Gulf of Mexico, Class III Waters. Portions of the project are within Outstanding Florida Waters associated with Barefoot Beach Preserve, Delnor-Wiggins Pass State Park and Wiggins Pass Estuarine Area and Cocohatchee River System. PROPRIETARY AUTHORIZATION: This activity also requires a proprietary authorization, as the activity is located on sovereign submerged lands held in trust by the Board of Trustees of the Internal Improvement Trust Fund (Board of Trustees), pursuant to Article X, Section 11 of the Florida Constitution, and Sections 253.002 and 253.77, F.S. The activity is not exempt from the need to obtain a proprietary authorization. The Board of Trustees delegated,to the Department,the responsibility to review and take final action on this request for proprietary authorization in accordance with Section 18-21.0051, F.A.C., and the Operating Agreements executed between the Department and the water management districts, as referenced in Chapter 62-113, F.A.C. This proprietary authorization has been reviewed in accordance with Chapter 253 F.S., Chapter 18-21, F.A.C., and the policies of the Board of Trustees. As staff to the Board of Trustees, the Department has reviewed the project described above, and has determined that the channel expansion,the channel maintenance and the dredged material placement activities qualify for a Letter of Consent to use sovereign, submerged lands, CAC January 10,2013 VII-8 Staff Report#2 87 of 173 Draft Joint Coastal Permit Wiggins Pass Navigation Channel Expansion and Maintenance Permit No. 0142538-008-JC Page 3 of 26 as long as the work performed is located within the boundaries as described herein and is consistent with the terms and conditions herein. Therefore, consent is hereby granted, pursuant to Chapter 253.77, F.S.,to perform the activity on the specified sovereign submerged lands. COASTAL ZONE MANAGEMENT: This permit constitutes a finding of consistency with Florida's Coastal Zone Management Program, as required by Section 307 of the Coastal Zone Management Act. WATER QUALITY CERTIFICATION: Granting the associated variance to the antidegradation provisions in Rule 62- 4.242(2)(a)2.b., F.A.C., authorizes the Permittee to exceed state water quality standards. Therefore, the Department hereby waives water quality certification pursuant to Section 401 of the Clean Water Act, 33 U.S.C. 1341. OTHER PERMITS: Authorization from the Department does not relieve you from the responsibility of obtaining other permits (Federal, State, or local)that may be required for the project. When the Department received your permit application, a copy was sent to the U.S. Army Corps of Engineers (Corps) for review. The Corps will issue their authorization directly to you, or contact you if additional information is needed. If you have not heard from the Corps within 30 days from the date that your application was received by the Department, contact the nearest Corps regulatory office for status and further information. Failure to obtain Corps authorization prior to construction could subject you to federal enforcement action by that agency.

Protection of Historical Resources. If sand is to be placed on the beach of Delnor Wiggins State Park, then the following conditions apply for the protection of historical resources: a. Because of the lack of site information for 8CR970, Delnor Wiggins Pass State Park Site,the Division of Historical Resources requires that a Phase II level cultural resource site assessment be conducted at the recorded site location to determine if the site is an archaeological site or an isolated find. In the case of an archeological site, sufficient testing should be conducted to determine the extent of the site,the eligibility for listing in the National Register of Historic Places, and/or if it is otherwise of archaeological value. This must occur before any sand can be placed at this location. b. If there is an archaeological resource, and this site is determined to meet National Register criteria, or is otherwise of archaeological value, further consultation with the Division of Historical Resources, the Department's JCP program and Delnor Wiggins Pass State Park cultural programs must occur to determine measures to avoid and/or minimize any effects to the site. CAC January 10,2013 VII-8 Staff Report#2 93 of 173 Draft Joint Coastal Permit Wiggins Pass Navigation Channel Expansion and Maintenance Permit No. 0142538-008-JC Page 9 of 26 c. Site 8CR218, Wiggins Pass Wreck South, must be located, GPS coordinates obtained, and the depth of deposits determined. The extent of the historic wreck site and an adequate buffer area should be clearly delineated on all project maps and on the ground during construction. This site must be avoided during beach nourishment activities associated with this permit, due to the nature and location of the site making it unable to be investigated, as well as the possibility that this site may be eligible for listing in the National Register. This includes all ground disturbing activities and heavy equipment operation associated with the initial placement of dredge material on the beach, and the subsequent annual tilling required a month prior to turtle nesting season. 8. Additional Coastal Engineering Condition. After the dredging Subarea D (channel realignment through the flood shoal, between C-3 and C-16) is completed,the Contractor shall be allowed to begin work in multiple subareas and to alternate between subareas. Once the Pemittee/Owner's Representative authorizes removal of the unsuitable material to begin from within a specified subarea (i.e., dredging of the suitable material has reached the threshold elevation), no additional material from within the specified subarea shall be allowed for beach or nearshore placement from that subarea. Material designated for beach, nearshore, ebb and flood shoal placement, as shown in the permit drawings, may be pumped directly to the respective placement site. The material designated for offshore disposal shall be placed in a barge for transport to the offshore disposal site at Borrow Area 6. A threshold elevation is identified for each subarea that contains clay, peat, silty sand (with silt content exceeding the sand standards in Rule 62B-41.007(2)(j), F.A.C.), or rock material. The Contractor shall be provided a tolerance above the threshold elevation for excavating material for beach or nearshore placement. The tolerance shall serve as a transition layer(overdredge allowance) between the material designated for beach or nearshore placement and the material that must be disposed as unsuitable material. The threshold elevation shall serve as a definitive line between the unsuitable material and the tolerance. 9. Sediment quality shall be assessed as outlined in the Sediment QA/QC plan dated July 3, 2012 (attached) for the initial construction. Any occurrences of placement of material not in compliance with the Plan shall be handled according to the protocols set forth in the Sediment QA/QC plan. The sediment testing result will be submitted to the Department within 90 days following the completion of beach construction. The Sediment QC/QA plan includes the following: CAC January 10,2013 VII-8 Staff Report#2 94 of 173 DI ail Joint Coastal Permit Wiggins Pass Navigation Channel Expansion and Maintenance Permit No. 0142538-008-JC Page 10 of 26 a. If during construction, the Permittee or Engineer determines that the beach fill material does not comply with the sediment compliance specifications, measures shall be taken to avoid further placement of noncompliant fill, and the sediment inspection results shall be reported to the Department. b. The Permittee shall submit post-construction sediment testing results and an analysis report as outlined in the Sediment QC/QA plan to the Department within 90 days following beach construction. The sediment testing results shall be certified by a P.E. or P.G. from the testing laboratory. A summary table of the sediment samples and test results for the sediment compliance parameters as outlined in Table 1 of the Sediment QC/QA plan shall accompany the complete set of laboratory testing results. A statement of how the placed fill material compares to the sediment analysis and volume calculations from the geotechnical investigation shall be included in the sediment testing results report. c. A post-remediation report containing the site map, sediment analysis, and volume of noncompliant fill material removed and replaced will be submitted to the Department within 7 days following completion of remediation activities. Prior to each maintenance dredge event, the sediment quality of the material to be dredged (after the initial dredge event) must be determined. The material must be tested and reviewed for beach compatibility. A Maintenance Dredging Sediment QA/QA plan shall be submitted with the final construction plans and specifications for subsequent maintenance dredging activities, and it shall include compliance values that are consistent with Rule 62B-41.007(2)(k), F.A.C. Manatee,Marine Turtle,and Shorebird Protection Conditions 10. During all construction authorized by this permit and subsequent to authorization of incidental take by the National Marine Fisheries Service (NMFS) and the U.S. Fish and Wildlife Service (Service) in accordance with Florida Statute 161.041 (5), 379.2431 (1), the Permittee shall comply with the following conditions intended to protect manatees, marine turtles and shorebirds from direct project effects: a. All personnel associated with the project shall be instructed about the presence of marine turtles, manatees and manatee speed zones, and the need to avoid collisions with (and injury to)these protected marine species.

All personnel associated with the project shall be instructed about the potential presence of nesting shorebirds and the need to avoid take of(including disturbance to)these protected species. h. All vehicles shall be operated in accordance with the FWC's Best Management Practices for Operating Vehicles on the Beach (http://myfwc.com/conservation/you-conserve/wildlife/beach-driving/). Specifically, the vehicle must be operated at a speed <6 mph and run at or below the high-tide line. Fish and Wildlife Protection Conditions for Dredging Activities: 11. Hopper Dredging. In the event a hopper dredge is utilized, the following requirements shall be met in addition to the Terms and Conditions of the applicable NMFS Regional Biological Opinion for Hopper Dredging (South Atlantic or Gulf of Mexico): a. Handling of captured sea turtle(s) shall be conducted only by persons with prior experience and training in these activities and who is duly authorized to conduct such activities through a valid Marine Turtle Permit issued by the Florida Fish and Wildlife Conservation Commission (FWC), pursuant to Florida Administrative Code (FAC) 68E-1. b. Standard operating procedure shall be that dredging pumps shall be disengaged by the operator, or the draghead bypass value shall be open and in use when the dragheads are not firmly on the bottom, to minimize impingement or entrainment of sea turtles within the water column. This precaution is especially important during the cleanup phase of dredging operations. c. A state-of-the-art rigid deflector draghead must be used on all hopper dredges in all channels at all times of the year. d. The Sea Turtle Stranding and Salvage Network(STSSN) Coordinator shall be notified at 1-904-573-3930 or via e-mail at AIIen.Foleyamyfwc.com of the start- CAC January 10,2013 VII-8 Staff Report#2 97 of 173 )raft Joint Coastal Permit Wiggins Pass Navigation Channel Expansion and Maintenance Permit No. 0142538-008-JC Page 13 of 26 up and completion of hopper dredging operations. In the event of capturing or recovering marine turtles or marine turtle parts,the STSSN should be contacted at 1-888-404-FWCC (3922). e. Relocation trawling or non-capture trawling shall be implemented in accordance with the applicable NMFS Biological Opinion and Incidental Take authorization. Any activity involving the use of nets to harass and/or to capture and handle marine turtles in Florida waters requires a Marine Turtle Permit from FWC. i. The permittee or their contractor shall e-mail (MTP( MyFWC.com) weekly reports to the Imperiled Species Management section on Friday each week that trawling is conducted in Florida waters. These weekly reports shall include: the species and number of turtles captured in Florida waters, general health, and release information. A summary (FWC provided Excel spreadsheet) of all trawling activity, including non-capture trawling, and all turtles captured in Florida waters, including all measurements, the latitude and longitude (in decimal degrees) of captures and tow start-stop points, and times for the start-stop points of the tows, including those tows on which no turtles are captured, shall be submitted to MTP(e6mvfwc.com by January 15 of the following year or at the end of the project. 12. Seabirds and Shorebirds. In cases where dredging activities have the potential to erode beaches or disturb Seabird or Shorebird breeding activities, Fish and Wildlife Protection Conditions for Beach Placement of Material apply. Fish and Wildlife Protection Conditions for Nearshore and Beach Placement of Dredge Material: 13. Beach Maintenance. All derelict concrete, metal, and coastal armoring material and other debris shall be removed from the beach prior to any material placement to the maximum extent practicable. If debris removal activities will take place during shorebird breeding or sea turtle nesting seasons,the work shall be conducted during daylight hours only and shall not commence until completion of daily seabird, shorebird or sea turtle surveys each day. All excavations and temporary alterations of the beach topography shall be filled or leveled to the natural beach profile prior to 9 p.m. each day unless otherwise authorized. 14. Pre-Construction Meeting. A meeting between representatives of the contractor, the US Fish and Wildlife Service (FWS), the FWC, the permitted sea turtle surveyor and Bird Monitors as appropriate), shall be held prior to commencement of work on projects. At least 10-business days advance notice must be provided prior to conducting this meeting. The meeting will provide an opportunity for explanation and/or clarification of the protection measures as well as additional guidelines when construction occurs during CAC January 10,2013 VII-8 Staff Report#2 98 of 173 ()raft Joint Coastal Permit Wiggins Pass Navigation Channel Expansion and Maintenance Permit No. 0142538-008-JC Page 14 of 26 nesting season, such as staging equipment and reporting within the work area as well as follow up meetings during construction. 15. Nesting Seabird and Shorebird Protection Conditions: Nesting seabird and shorebird surveys should be conducted by trained, dedicated individuals(Bird Monitor)with proven shorebird identification skills and avian survey experience. A list of candidate Bird Monitors with their contact information, summary of qualifications including bird identification skills, and avian survey experience shall be provided to the DEP and FWC. This information will be submitted to the FWC regional biologist (contact information attached)prior to any construction or hiring for shorebird surveys for revision and consultation. Bird Monitors shall use the following survey protocols: a. Bird Monitors shall review and become familiar with the general information, employ the data collection protocol, and implement data entry procedures outlined on the FWC's Florida Shorebird Database (FSD)website (www.FLShorebirdDatabase.org). An outline of data to be collected, including downloadable field data sheets, is available on the website. b. Breeding season varies by species. Most species have completed the breeding cycle by September 1, but flightless young may be present through September. The following dates are based on the best available information regarding ranges and habitat use by species around the state: All Gulf Coast counties: February 15 —September 1 Breeding season surveys shall begin on the first day of the breeding season or 10 days prior to project commencement (including surveying activities and other pre- construction presence on the beach), whichever is later. Surveys shall be conducted through August 31st or until all breeding activity has concluded, whichever is later. c. Breeding season surveys shall be conducted in all potential beach-nesting bird habitats within the project boundaries that may be impacted by construction or pre-construction activities. Portions of the project in which there is no potential for project-related activity during the nesting season may be excluded. One or more shorebird survey routes shall be established in the FSD website to cover these areas. d. During the pre-construction and construction phases of the project, surveys for detecting breeding activity and the presence of flightless chicks will be completed on a daily basis prior to movement of equipment, operation of vehicles, or other activities that could potentially disrupt breeding behavior or cause harm to the birds or their eggs or young. CAC January 10,2013 VII-8 Staff Report#2 99 of 173 Draft Joint Coastal Permit Wiggins Pass Navigation Channel Expansion and Maintenance Permit No. 0142538-008-JC Page 15 of 26 e. Surveys shall be conducted by walking the length of the project area and visually surveying for the presence of shorebirds exhibiting breeding behavior, shorebird/seabird chicks, or shorebird/seabird juveniles as outlined in the FSD Breeding Bird Protocol for Shorebirds and Seabirds. Use of binoculars is required. i. If an ATV or other vehicle is needed to cover large project areas, operators will adhere to the FWC's Best Management Practices for Operating Vehicles on the Beach (http://myfwc.com/conservation/vou- conserve/wildlife/beach-driving/). Specifically, the vehicle must be operated at a speed<6 mph and run at or below the high-tide line. The Bird Monitor will stop at no greater than 200 meter intervals to visually inspect for breeding activity. f. Once breeding is confirmed by the presence of a scrape, eggs, or young,the Bird Monitor will notify the FWC Regional Species Conservation Biologist(contact information attached) within 24 hours. All breeding activity will be reported to the FSD website within one week of data collection. 16. Seabird and Shorebird Buffer Zones and Travel Corridors. Within the project area, the permittee shall establish a disturbance-free buffer zone around any location where shorebirds have been engaged in breeding behavior, including territory defense. A 300 ft-wide buffer is considered adequate based on published studies. However, a smaller, site-specific buffer may be implemented upon approval by the FWC Regional Species Conservation Biologist(contact information attached) as needed. All sources of human disturbance (including pedestrians, pets, and vehicles) shall be prohibited in the buffer zone. a. The Bird Monitor shall keep breeding sites under sufficient surveillance to determine if birds appear agitated or disturbed by construction or other activities in adjacent areas. If birds do appear to be agitated or disturbed by these activities, then the width of the buffer zone shall be increased immediately to a sufficient size to protect breeding birds. b. Reasonable and traditional pedestrian access should not be blocked where breeding birds will tolerate pedestrian traffic. This is generally the case with lateral movement of beach-goers walking parallel to the beach at or below the highest tide line. Pedestrian traffic may also be tolerated when breeding was initiated within 300 feet of an established beach access pathway. The Permittee shall work with the FWC Regional Species Biologist to determine if pedestrian access can be accommodated without compromising nesting success. c. Designated buffer zones must be marked with posts,twine, and signs stating"Do Not Enter, Important Nesting Area"or similar language around the perimeter CAC January 10,2013 VII-8 Staff Report#2 100 of 173 Draft Joint Coastal Permit Wiggins Pass Navigation Channel Expansion and Maintenance Permit No. 0142538-008-JC Page 16 of 26 which includes the name and a phone number of the entity responsible for posting. Posts should not exceed 3' in height once installed. Symbolic fencing (twine, string, or rope) should be placed between all posts at least 2.5' above the ground and rendered clearly visible to pedestrians. If pedestrian pathways are approved by the FWC Regional Species Conservation Biologist within the 300- foot buffer zone,these should be clearly marked. The posting shall be maintained in good repair until breeding is completed or terminated. Although solitary nesters may leave the buffer zone with their chicks, the posted area continues to provide a potential refuge for the family until breeding is complete. Breeding is not considered to be completed until all chicks have fledged. d. No construction activities, pedestrians, movement of vehicles, or stockpiling of equipment shall be allowed within the buffer area. e. Travel corridors shall be designated and marked outside the buffer areas so as not to cause disturbance to breeding birds. Heavy equipment, other vehicles, or pedestrians may transit past breeding areas in these corridors. However, other activities such as stopping or turning shall be prohibited within the designated travel corridors adjacent to the breeding site. When flightless chicks are present within or adjacent to travel corridors, movement of vehicles shall be accompanied by the Bird Monitor who will ensure no chicks are in the path of the moving vehicle and no tracks capable of trapping flightless chicks result. f. To discourage nesting within the travel corridor, it is recommended that the Permittee should maintain some activity within these corridors on a daily basis, without disturbing any nesting shorebirds documented on site or interfering with sea turtle nesting, especially when those corridors are established prior to commencement of construction. 17. Notification. If shorebird breeding occurs within the project area, a bulletin board will be placed and maintained in the construction staging area with the location map of the construction site showing the bird breeding areas and a warning, clearly visible, stating that"NESTING BIRDS ARE PROTECTED BY LAW INCLUDING THE FLORIDA ENDANGERED AND THREATENED SPECIES ACT AND THE STATE and FEDERAL MIGRATORY BIRD ACTS". 18. Marine Turtle Nest Surveys and Relocation. All sand placement shall occur outside the marine turtle nesting season, May 1 through October 31. The following marine turtle protection conditions shall be met during such work;FWC may recommend incorporation of any additional terms and conditions specified in the federal incidental take authorization through modification prior to commencement of construction. CAC January 10,2013 VII-8 Staff Report#2 101 of 173 Draft Joint Coastal Permit Wiggins Pass Navigation Channel Expansion and Maintenance Permit No. 0142538-008-JC Page 17 of 26 Marine turtle nesting surveys shall be initiated 65 days prior to sand placement activities or by April 15 whichever is later and shall comply with the following requirements ones). a. Nesting surveys and nest marking will only be conducted by persons with prior experience and training in these activities and who are authorized to conduct such activities through a valid permit issued by FWC, pursuant to FAC 68E-1. Please contact FWC's Marine Turtle Management Program in Tequesta at MTP@mvfwc.com for information on the permit holder in the project area. Nesting surveys shall be conducted daily between sunrise and 9 a.m. (this is for all time zones). The contractor shall not initiate work until daily notice has been received from the marine turtle permit holder that the morning survey has been completed. Surveys shall be performed in such a manner so as to ensure that construction activity does not occur in any location prior to completion of the necessary marine turtle protection measures. b. Nests shall be left in place and marked for avoidance unless other factors threaten the success of the nest(nest laid below debris line marking the typical high tide, erosion). The Marine Turtle Permit Holder shall install an on-beach marker at the nest site and a secondary marker at a point as far landward as possible to assure that future location of the nest will be possible should the on-beach marker be lost. The actual location of the clutch will be determined and nests will be marked. A series of stakes and highly visible survey ribbon or string shall be installed to establish a three-foot radius around the nest. No activity shall occur within this area nor will any activity occur that could result in impacts to the nest. Nest sites shall be inspected daily to assure nest markers remain in place and that the nest has not been disturbed by the project activity. Nest relocation is only allowed if nests laid within the travel corridor(beach access to MHWL) cannot be rerouted to avoid the nest. 19. To the maximum extent possible within the travel corridor, all ruts shall be filled or leveled to the natural beach profile prior to completion of daily construction during shorebird nesting season. 20. If entrapment of sea turtle hatchlings occurs in the groin or jetty system during construction, the permittee shall contact FWC immediately. 21. Marine Turtle or Nest Encounters. Upon locating a dead or injured sea turtle adult, hatchling or egg that may have been harmed or destroyed as a direct or indirect result of the project, the Corps, applicant, and/or local sponsor shall be responsible for notifying FWC Wildlife Alert at 1-888-404-FWCC (3922). Care shall be taken in handling injured sea turtles or eggs to ensure effective treatment or disposition, and in handling dead specimens to preserve biological materials in the best possible state for later analysis. In the event a sea turtle nest is excavated during construction activities,the permitted person CAC January 10,2013 VII-8 Staff Report#2 102 of 173 Draft Joint Coastal Permit Wiggins Pass Navigation Channel Expansion and Maintenance Permit No. 0142538-008-JC Page 18 of 26 responsible for egg relocation for the project shall be notified immediately so the eggs can be moved to a suitable relocation site. 22. Equipment Storage and Placement. All construction pipes that are placed on the beach shall be located as far landward as possible without compromising the integrity of the existing or reconstructed dune system. Pipes placed parallel to the dune shall be 5 to 10 feet away from the toe of the dune. Temporary storage of pipes shall be off the beach to the maximum extent possible. If it will be necessary to extend construction pipes past a known shorebird nesting site or over-wintering area for piping plovers, then whenever possible those pipes shall be placed landward of the site before birds are active in that area. No pipe or sand shall be placed seaward of a shorebird nesting site during the shorebird nesting season. 23. Compaction Sampling. Sand compaction shall be monitored in the area of sand placement immediately after completion of the project and prior to April 15th for three (3) subsequent years and shall be monitored in accordance with a protocol agreed to by the FWS, FWC, and the applicant or local sponsor. The requirement for compaction monitoring can be eliminated if the decision is made to till regardless of post-construction compaction levels. Out-year compaction monitoring and remediation are not required if placed material no longer remains on the beach. At a minimum, the protocol provided under a. and b. below shall be followed. If the average value for any depth exceeds 500 pounds per square inch (psi) for any two or more adjacent stations,then that area shall be tilled immediately prior to the following date listed above. If values exceeding 500 psi are distributed throughout the project area but in no case do those values exist at two adjacent stations at the same depth,then consultation with the FWC or FWS will be required to determine if tilling is required. If a few values exceeding 500 psi are present randomly within the project area,tilling will not be required. a. Compaction sampling stations shall be located at 500-foot intervals along the project area. One station shall be at the seaward edge of the dune/bulkhead line (when material is placed in this area), and one station shall be midway between the dune line and the high water line(normal wrack line). b. At each station, the cone penetrometer shall be pushed to a depth of 6, 12, and 18 inches three times (three replicates). Material may be removed from the hole if necessary to ensure accurate readings of successive levels of sediment. The penetrometer may need to be reset between pushes, especially if sediment layering exists. Layers of highly compact material may lie over less compact layers. Replicates shall be located as close to each other as possible, without interacting with the previous hole and/or disturbed sediments. The three replicate compaction values for each depth shall be averaged to produce final values for CAC January 10,2013 VII-8 Staff Report#2 103 of 173 )raft Joint Coastal Permit Wiggins Pass Navigation Channel Expansion and Maintenance Permit No. 0142538-008-JC Page 19 of 26 each depth at each station. Reports will include all 18 values for each transect line, and the final 6 averaged compaction values. c. No compaction sampling shall occur within 300 feet of any shorebird nest. d. Any vehicles operated on the beach in association with compaction surveys shall operate in accordance with the FWC's Best Management Practices for Operating Vehicles on the Beach (http://myfwc.com/conservation/vou- conserve/wildlife/beach-driving/). 24. Tilling Requirements. If tilling is required as specified above,the area shall be tilled to a depth of 36 inches. All tilling activity shall be completed prior to the marine turtle nesting season. If tilling occurs during shorebird nesting season (See 15b above), shorebird surveys prior to tilling shall be required per the Shorebird Conditions included within this document. It is the responsibility of the contractors to avoid tilling, scarp removal, or dune vegetation planting in areas where nesting birds are present. Each pass of the tilling equipment shall be overlapped to allow thorough and even tilling. If the project is completed during the marine turtle nesting season, tilling will not be performed in areas where nests have been left in place or relocated. If compaction measurements are taken, a report on the results of the compaction monitoring shall be submitted electronically to FWC at marineturtle(u)mvfwc.com prior to any tilling actions being taken. a. No tilling shall occur within 300 feet of any shorebird nest. b. If flightless shorebird young are observed within the work zone or equipment travel corridor, a Shorebird Monitor shall be present during the operation to ensure that equipment does not operate within 300 feet of the flightless young. c. A relatively even surface, with no deep ruts or furrows, shall be created during tilling. To do this, chain-linked fencing or other material shall be dragged over those areas as necessary after tilling. d. Tilling shall occur landward of the wrack line and avoid all vegetated areas 3 square feet or greater with a 3 square foot buffer around the vegetated areas. The slope between the mean high water line and the mean low water line must be maintained in such a manner as to approximate natural slopes. e. Any vehicles operated on the beach in association with tilling shall operate in accordance with the FWC's Best Management Practices for Operating Vehicles on the Beach (http://myfwc.com/conservation/vou-conserve/wildlife/beach- driving/). CAC January 10,2013 VII-8 Staff Report#2 104 of 173 Draft Joint Coastal Permit Wiggins Pass Navigation Channel Expansion and Maintenance Permit No. 0142538-008-JC Page 20 of 26 25. Escarpment Surveys. Visual surveys for escarpments along the project area shall be made immediately after completion of the sand placement project,weekly during sea turtle nesting season, and during March 15 to April 15 for three (3) subsequent years if sand from the project area still remains on the beach. Escarpments that interfere with sea turtle nesting or that exceed 18 inches in height for a distance of at least 100 feet shall be leveled and the beach profile shall be reconfigured to minimize scarp formation by April 15. Any escarpment removal shall be reported by location. If the project is completed during the sea turtle nesting and hatching season, escarpments may be required to be leveled immediately, while protecting nests that have been relocated or left in place. FWC shall be contacted immediately if subsequent reformation of escarpments that interfere with sea turtle nesting or that exceed 18 inches in height for a distance of 100 feet occurs during the nesting and hatching season to determine the appropriate action to be taken. If it is determined that escarpment leveling is required during the nesting or hatching season, the FWS or FWC will provide a brief written authorization that describes methods to be used to reduce the likelihood of impacting existing nests. An annual summary of escarpment surveys and actions taken shall be submitted electronically to marineturtle @mvfwc.com along with the annual summary as described below. If escarpment removal occurs during shorebird breeding season (See 16b), shorebirds surveys shall be required per the Shorebird Conditions included within this document prior to removal. (NOTE: Out-year escarpment monitoring and remediation are not required if placed material no longer remains on the dry beach). a. No heavy equipment shall operate within 300 feet of any shorebird nest. b. If flightless shorebird young are observed within the work zone or equipment travel corridor, a Shorebird Monitor shall be present during the operation to ensure that equipment does not operate within 300 feet of the flightless young. c. Any vehicles operated on the beach in association with escarpment surveys or removal shall operate in accordance with the FWC's Best Management Practices for Operating Vehicles on the Beach (http://myfwc.com/conservation/You- conserve/wildlife/beach-driving/). Post-construction Shorebird Protection Conditions: 26. If beach cleaning will occur on the nourished beach, a minimum of 30%of the biotic material within the wrack line will be left on the beach post-cleaning at the strand line in a natural configuration to ensure that the nourished beach re-establishes its function as foraging habitat for shorebirds. This shall occur for as long as the placed sand remains on the beach. Post-construction Monitoring and Reporting Marine Turtle Protection Conditions: CAC January 10,2013 VII-8 Staff Report#2 105 of 173 Draft Joint Coastal Permit Wiggins Pass Navigation Channel Expansion and Maintenance Permit No. 0142538-008-JC Page 21 of 26 27. Reports on all marine turtle nesting activity shall be provided for the initial marine turtle nesting(May 1 through September 15) and hatching (through October 31) season and for up to three additional nesting seasons as follows: a. For the initial nesting season and the following year,the number and type of emergences (nests or false crawls) shall be reported per species in accordance with the Table below. An additional year of nesting surveys may be required if nesting success for any species on the nourished beach is less than 40%. b. For the initial nesting season, reproductive success shall be reported per species in accordance with the Table below. Reproductive success shall be reported for all sea turtle nests if possible. Otherwise a statistically significant number of nests for each species shall be reported. c. In the event that the reproductive success documented by species meets or exceeds required criteria(outlined in Table below) for each species, monitoring for reproductive success shall be recommended, but not required for the second year post-construction. d. Monitoring of nesting activity in the seasons following construction shall include daily surveys and any additional measures authorized by the FWC. Summaries shall include all crawl activity, nesting success rates, hatching success of all relocated nests, hatching success of a representative sampling of nests left in place (if any)by species, project name and applicable project permit numbers and dates of construction. Data should be reported for the nourished areas in accordance with the Table below and should include number of nests lost to erosion or washed out.

MONITORING REQUIRED: 30. Water Quality. Turbidity shall be monitored during the dredging and placement (disposal) activities for this project as follows: Units: Nephelometric Turbidity Units (NTUs). Frequency: Approximately every 4 hours during dredging and disposal, while the maximum turbidity plume crosses the edge of the mixing zone. Location: Background: At least 500 meters upcurrent of both the dredging and disposal locations, outside the influence of any visible turbidity plume, at the surface and mid-depths. Compliance 1 (disposal sites): In the densest portion of the turbidity plume, downcurrent from the source of turbidity, at the surface and mid- depths, not more than 150 meters from the discharge point or at the location of the nearest hardbottom edge,whichever is less. Compliance 2 (dredge site): In the densest portion of the turbidity plume, downcurrent from the source of turbidity, at the surface and mid-depths, not more than 300 meters from the dredge cutterhead, or at the location of the nearest seagrass edge, whichever is less. The compliance locations given above shall be considered the limits of the temporary mixing zone for turbidity allowed during construction. Standards: Within OFW: When the mixing zone extends into OFW,turbidity at the compliance site shall not be greater than ten (10)NTUs above the corresponding background measurement. Outside OFW: At the edge of mixing zones terminating outside of OFW, compliance turbidity levels shall not be greater than 29 NTUs above the corresponding background measurement.

This document will address potential effects of the proposed project on the threatened piping plover(Charadrius melodus),threatened loggerhead sea turtle (Caretta caretta),endangered leatherback sea turtle(Dermochelys coriacea), endangered green sea turtle(Chelonia mydas), endangered hawksbill sea turtle(Eretmochelys imbricate). endangered Kemp's ridley sea turtle(Lepidochelys kempii),and endangered West Indian manatee (Trichechus manatus). This document is provided in accordance with section 7 of the Endangered Species Act of 1973,as amended(Act)(87 Stat. 884; 16 U.S.C. 1531 et seq.). This Biological Opinion is based on information provided in the Corps' letter dated February 23,2012,Public Notice, and correspondence with the Corps,National Oceanic Atmospheric Administration's National Marine Fisheries Service(NOAA Fisheries), and the Florida Pith and Wildlife Cunsetvatiutr Cuu11111Ssiuit (FWC). A euttuplete administrative record of this consultation is on file at the South Florida Ecological Services Office, Vero Beach, Florida. FISH AND WILDLIFE RESOURCES Hardbottom reef habitat and seagrasses No hardbottom habitat or seagrass in the nearshore zones out to a depth of-30 feet North American Vertical Datum have been documented based on historic information and surveys,and recent surveys. That said;the permit will not authorize impacts to seagrass or nearshore TAKE PRIDE'.** NAM ER ICA CAC January 10,2013 VII-8 Staff Report#2 115 of 173 EFFECT OF THE TAKE In this Biological Opinion, the Service determined the proposed project is not likely to result in jeopardy to piping plovers or result in destruction or adverse modification of critical habitat. REASONABLE AND PRUDENT MEASURES The Service believes the following reasonable and prudent measures are necessary and appropriate to minimize take of nonbreeding piping plovers in the proposed action area. 1. The Applicant shall minimize and monitor the effects of the proposed project on piping plovers. 2. After project completion, the Applicant shall protect wrack and inlet shorelines for roosting and foraging piping plovers. 3. Preconstruction project information collected in Term and Condition#1 shall be submitted to the South Florida Ecological Services Office. 4. Prior to construction, avoidance signs shall be installed around optimal piping plover habitat features. 5. Driving on the beach shall be limited to that necessary and within a travel corridor. 6. Postconstruction signage will be placed within the action area to protect piping plover habitat features. 7. The Applicant shall educate the public to minimize disturbance to piping plovers. 8. The Applicant shall comply with the MBTA and FWC's shorebird guidelines. 9. The Applicant shall minimize the presence of predators. 10. The Corps shall ensure communication between all parties is carried out. TERMS AND CONDITIONS In order to be exempt from the prohibitions of section 9 of the Act, the Corps and Applicant must comply with the following terms and conditions, which implement the reasonable and prudent measures described above, and outline required reporting and monitoring requirements. These terms and conditions are nondiscretionary. 1. For 3 months prior to construction and for 3 years following each sand placement event, the Applicant must conduct bi-monthly (twice-monthly) surveys for piping plovers in the beach fill template within the action area covering the nonbreeding season for plovers 37 CAC January 10,2013 VII-8 Staff Report#2 116 of 173 (July 15 to May 15 of each year) to monitor and quantify the level of take associated with the project and to evaluate the potential effects of future projects of similar nature. At least one of the bi-monthly surveys should be conducted on a weekend during each of the months of October, November, March and April. Piping plover identification,especially when in non-breeding plumage, can be difficult. Qualified professionals with shorebird/habitat survey experience must conduct the required field work. The following will be collected and reported: a. Negative and positive survey data. b. The amount and type of recreational use (e.g., people, dogs on-off leash, vehicles, kite-boarders). c. Piping plover locations with a Global Positioning System(decimal degrees preferred). d. Habitat feature(s) used by piping plovers when observed (e.g., intertidal,fresh wrack, old wrack,dune, mid-beach, vegetation). e. Landscape feature(s) where piping plovers are located (e.g., inlet spit, tidal creek, shoals, lagoon shoreline). f. Substrate used by piping plovers (e.g., sand, mud/sand, mud, algal mat). g. Behavior of piping plovers (e.g., foraging, roosting, preening, bathing,flying, aggression, walking). h. Color bands observed on piping plovers. i. All other shorebirds/waterbirds seen within the survey area. All information shall be incorporated into a database. Submit pre-and postconstruction piping plover monitoring results (datasheets, maps, database) on standard electronic media(e.g., CD, DVD) to the FWC, and to the Service's South Florida Ecological Services Office (1339 20th Street, Vero Beach,Florida 32960-3559; 772-562-3909). All reports will be due by December 1 following the end of the nonbreeding season for plovers (July 15) of each year. 2. To preserve piping plover feeding and roosting habitat, the Applicant or upland owners shall limit mechanical cleaning of the dry sand portion of the beach to areas landward of the primary wrack(organic material) line as reasonable determined by the Applicant or upland owners for the life of the project. This has been identified as important foraging and roosting habitat by piping plovers as well as an abundance of other shorebirds for wintering and migrating. Trash and litter within the wrack line area may be manually removed. Mechanical removal of wrack may be auth6r12ed Wheri the Applicant or upland owners document a fish kill event, or when the health of humans may be affected. The Applicant will notify the Service via phone or electronic mail when wrack removal is necessary. 3. Prior to construction, the Applicant shall submit to the South Florida Ecological Services Office, a project design which incorporates the information collected in Term and Condition#1 documenting how project impacts have been minimized to the maximum extent practicable without jeopardizing the permitted design or construction methods. 38 CAC January 10,2013 VII-8 Staff Report#2 117 of 173 4. Prior to construction, the Applicant shall post avoidance signs around any optimal piping plover habitat features identified in Term and Condition#1 within the project area, and protect these areas from sediment fill to the maximum extent practicable. Obvious identifiers (e.g., pink flagging tape on metal poles) shall be used to clearly mark the boundaries to prevent accidental impacts to these areas. 5. If project construction requires driving on the beach outside of the project area, driving on the beach for construction shall be limited to the minimum necessary with a travel corridor established to above the primary wrack line. 6. Postconstruction signage shall be placed within the action area to protect the habitat features documented as used by piping plovers. When County pet ordinances are in place, that information shall be integrated into the signage. If possible, warnings and citations will be issued when appropriate to minimize harassment of piping plovers and other shorebirds protected under the MBTA. 7. The Applicant shall produce piping plover and wrack-oriented educational materials to be placed on the County's website. The goal of these outreach activities is to educate the public about piping plover optimal habitat,the role of natural coastal processes in creating and maintaining piping plover habitat,and the importance of wrack. Some of the educational information will be included in a preconstruction news release. 8. Due to the potential for the proposed project to affect piping plovers, the Applicant shall comply with the MBTA and follow FWC's standard guidelines to protect against effects to nesting shorebirds during implementation of the proposed project during the periods from February 15 to August 31. In part, these guidelines include the establishment of buffer zones in locations where shorebirds have been engaged in nesting behavior, including territory defense. 9. The Applicant shall ensure the contractors conducting the work provide predator proof trash receptacles for all construction workers. All contractors and their employees shall be briefed on the importance of not littering and keeping the project area trash and debris free. Predator proof trash receptacles shall be installed and maintained at all access points,eating areas, and restroom areas. 10. The Corps shall submit a report describing the actions taken to implement the terms and conditions of this incidental take statement to the FWC, Imperiled Species Management Section,Tallahassee office and the Service's South Florida Ecological Services Office, Vero Beach, Florida within 60 days postconstruction of each event. 10a. The Corps must arrange a meeting between representatives of the contractor, the Service,the FWC, and the shorebird surveyor(s) prior to the commencement of the project and prior to each future event. 39 CAC January 10,2013 VII-8 Staff Report#2 118 of 173 Upon locating a dead, injured, or sick threatened piping plover specimen, initial notification must be made to the Service's Office of Law Enforcement(10426 NW 31St Terrace,Miami, Florida 33172; 305-526-2610). Additional notification must be made to FWC at 1-888-404-3922 and the Service's South Florida Ecological Services Office (1339 2011' Street,Vero Beach, Florida 32960-3559; 772-562-3909). Care should be taken in handling sick or injured specimens to ensure effective treatment and care and in handling dead specimens to preserve biological materials in the best possible state for later analysis of cause of death. In conjunction with the care of sick or injured endangered or threatened species or preservation of biological materials from a dead animal,the finder has the responsibility to ensure evidence intrinsic to the specimen is not unnecessarily disturbed. CONSERVATION RECOMMENDATIONS Section 7(a)(1) of the Act directs Federal agencies to utilize their authorities to further the purposes of the Act by carrying out conservation programs for the benefit of endangered and threatened species. Conservation recommendations are discretionary agency activities to minimize or avoid adverse effects of a proposed action on listed species or critical habitat, to help implement recovery plans, or to develop information. • To further protect piping plover habitat and reduce beach erosion, the Applicant should consider protecting the wrack throughout the project area in perpetuity. In order for the Service to be kept informed of actions minimizing or avoiding adverse effects or benefiting listed species or their habitats, the Service requests notification of the implementation of any conservation recommendations. THE MIGRATORY BIRD TREATY ACT The MBTA implements various treaties and conventions between the U.S., Canada,Japan, Mexico, and the former Soviet Union for the protection of migratory birds. Under the provisions of the MBTA, it is unlawful "by any means or manner to pursue,hunt, take, capture or kill any migratory bird except as permitted by regulations issued by the Service. The term "take" is not defined in the MBTA, but the Service has defined it by regulation to mean to pursue, hunt, shoot, wound, kill, trap,capture or collect any migratory bird, or any part, nest or egg or any migratory bird covered by the conventions or to attempt those activities. In order to comply with the MBTA and due to the potential for this project to affect nesting shorebirds, the Corps and Sponsor should follow FWC's standard guidelines to protect against effects to nesting shorebirds during implementation of this project during the periods from February 15 to August 31. The Service will not refer the incidental take of piping plover for prosecution under the MBTA of 1918, as amended (16 U.S.C. 703-712), if such take is in compliance with the terms and conditions specified in the incidental take statement above. 40 CAC January 10,2013 VII-8 Staff Report#2 119 of 173 C-3b U.S. Fish & Wildlife Services Statewide Programmatic Biological Opinion April 19,2011 Excerpt pp 102-120 CAC January 10,2013 VII-8 Staff Report#2 120 of 173 United States Department of the Interior 71"-� U.S. FISH AND WILDLIFE SERVICE 7915 BAYMEADOWS WAY,SUITE 200 JACKSONVILLE,FLORIDA 32256-7517 W REPLY REFER TO: FWS Log Number:41910-2011-F-0170 April 19, 2011 Colonel Alfred A.

Each pass of the tilling equipment shall be overlapped to allow more thorough and even tilling. All tilling activity shall be completed at least once prior to the nesting season. An electronic copy of the results of the compaction monitoring shall be submitted to the appropriate Service Field Office(Table 3)prior to any tilling actions being taken or if a request not to till is made based on compaction results. The requirement for compaction monitoring can be eliminated if the decision is made to till regardless of post construction compaction levels. Additionally,out-year compaction monitoring and remcdiation are not required if placed material no longer remains on the dry beach. (NOTE:If tilling occurs during shorebird nesting season(February 15-August 31), shorebird surveys prior to tilling are required per the Migratory Bird Treaty Act http://myfwc.com/dots/Conservation/FBCI_BNB_SeaTurtleMonitors.pdf) a. Compaction sampling stations shall be located at 500-foot intervals along the sand placement template. One station shall be at the seaward edge of the dune/bulkhead line(when material is placed in this area),and one station shall be midway between the dune line and the high water line(normal wrack line). b. At each station,the cone penetrometer shall be pushed to a depth of 6, 12,and 18 inches three times(three replicates). Material may be removed from the hole if necessary to ensure accurate readings of successive levels of sediment. The penetrometer may need to be reset between pushes,especially if sediment layering 112 CAC January 10,2013 VII-8 Staff Report#2 132 of 173 exists. Layers of highly compact material may lie over less compact layers. Replicates shall be located as close to each other as possible,without interacting with the previous hole or disturbed sediments. The three replicate compaction values for each depth shall be averaged to produce final values for each depth at each station. Reports will include all 18 values for each transect line,and the final six averaged compaction values. c. If the average value for any depth exceeds 500 pounds per square inch (psi)for any two or more adjacent stations,then that area shall be tilled immediately prior to the appropriate date listed in Table 18. d. If values exceeding 500 psi are distributed throughout the project area but in no case do those values exist at two adjacent stations at the same depth,then consultation with the Service will be required to determine if tilling is required. If a few values exceeding 500 psi are present randomly within the project area,tilling will not be required. e. Tilling shall occur landward of the wrack line and avoid all vegetated areas 3 square • feet or greater with a 3 square foot buffer around the vegetated areas. A13, Visual surveys for escarpments along the project area shall be made immediately after completion of the sand placement and within 30 days prior to the start dates for Nesting Season Monitoring in Tables 15 and 16 for 3 subsequent years if sand in the project area still remains on the dry beach. Escarpments that interfere with sea turtle nesting or that exceed 18 inches in height for a distance of 100 feet shall be leveled and the beach profile shall be reconfigured to minimize scarp formation by the dates listed above. Any escarpment removal shall be reported by location. If the project is completed during the early part of the sea turtle nesting and hatching season(March 1 through April 30),escarpments may be required to be leveled immediately,while protecting nests that have been relocated or left in place. The Service shall be contacted immediately if subsequent reformation of escarpments that interfere with sea turtle nesting or that exceed 18 inches in height for a distance of 100 feet occurs during the nesting and hatching season to determine the appropriate action to be taken. If it is determined that escarpment leveling is required during the nesting or hatching season,the Service or FWC will provide a brief written authorization within 30 days that describes methods to be used to reduce the likelihood of impacting existing nests. An annual summary of escarpment surveys and actions taken shall be submitted to the appropriate Service Field Office(Table 3). A14. If available,staging areas for construction equipment shall be located off the beach during early(March I through April 30)and late(November 1 through November 30)nesting season for Brevard through 13roward counties and peak nesting season(May 1 through October 31)for the remaining counties. Nighttime storage of construction equipment not in use shall be off the beach to minimize disturbance to sea turtle nesting and hatching activities. In addition,all construction pipes placed on the beach shall be located as far landward as possible without compromising the integrity of the dune system. Pipes placed parallel to the dune shall be 5 to 10 feet away from the toe of the dune if the width of the 113 CAC January 10,2013 VII-8 Staff Report#2 133 of 173 beach allows, Temporary storage of pipes shall be off the beach to the maximum extent possible, If the pipes are stored on the beach,they shall be placed in a manner that will minimize the impact to nesting habitat and shall not compromise the integrity of the dune systems. A15. Direct lighting of the beach and nearshore waters shall be limited to the immediate construction area during early,(Mareh 1 through April 30)and late(November 1 through November 30)nesting season for Brevard through Broward counties and peak nesting season(May 1 through October 31)for the remaining counties,and shall comply with safety requirements. Lighting on all equipment shall be minimized through reduction, shielding,lowering, and appropriate placement to avoid excessive illumination of the • water's surface and nesting beach while meeting all Coast Guard,Corps EM 385-1-1,and OSI-IA requirements. Light intensity of lighting equipment shall be reduced to the • minimum standard required by OSHA for General Construction areas, in order not to misdirect sea turtles. Shields shall be affixed to the light housing and be large enough to block light from all lamps from being transmitted outside the construction area or to the adjacent sea turtle nesting beach in line-of-sight of the dredge(Figure 15). • .:,•�.;s:; ,..r."9"GSx::.%vi«'+�+�:^;: `'.^x„�'t°: ^'c:F'•;,•'„ •s:s:: -:,r_::a<%�•.:vv;:;s .;;�<,: .•bv. >/rte ti\.:i.+:ri:•.�'r, ir• •Yti� .t '.4 A1;tt.ti rN. p?,,4, 4A��p',l.ht,;l•,t',il�;w.:1�,i::.;r,.e 2 y;�a:t�J:#`..�'.t�`y:\k.#?i f 41:W c 1�?• T I;a : e�iO ya ; WORK A A " ?G A , r 0'44 ? , ;ii� s �4. q4� v . own aw ��4'S �0� 0.� v. �i.+.

During the period during early(March 1 through April 30)and late(November 1 through November 30) nesting season for Brevard through Broward counties and peak nesting season(May I through October 31)for the remaining counties,the contractor shall not extend the beach fill more than 500 feet(or other agreed upon length)along the shoreline between dusk and dawn of the following day until the daily nesting survey has been completed and the beach cleared for fill advancement. An exception to this may occur if there is a permitted sea turtle surveyor present on-site to ensure no nesting and hatching sea turtles are present within the extended work area. If the 500 feet is not feasible for the 114 CAC January 10,2013 VII-8 Staff Report#2 134 of 173 project,an agreed upon distance will be decided on during the preconstruction meeting. Once the beach has been cleared and the necessary nest relocations have been completed, the contractor will be allowed to proceed with the placement of fill during daylight hours until dusk at which time the 500-foot length(or other agreed upon length)limitation shall apply. If any nesting turtles arc sighted on the beach within the immediate construction area,activities shall cease immediately until the turtle has returned to the water and the sea turtle permit holder responsible for nest monitoring has relocated the nest. Dune Planting A17. All vegetation planting shall be designed and conducted to minimize impacts to sea turtles and beach mice. Dune vegetation planting may occur during the sea turtle nesting season under the following conditions. a. Daily early morning sea turtle nesting surveys(before 9 a.m.)shall be conducted during the period from May I through October 31 for all counties in Florida where sea turtle nesting occurs. If the planting is conducted in Brevard, Indian River,St. Lucie,Martin, Palm Beach,or Broward Counties,daily early morning surveys shall be extended to include March 1 through April 30 and November 1 through November 30. Nesting surveys shall only be conducted by personnel with prior experience and training in nesting surveys. Surveyors shall have a valid FWC permit. Nesting surveys shall be conducted daily between sunrise and 9 a.m.(all times). No dune planting activity shall occur until after the daily turtle survey and nest conservation and protection efforts have been completed. Hatching and emerging success monitoring will involve checking nests beyond the completion date of the daily early morning nesting surveys; b. Any nests deposited in the dune planting area not requiring relocation for conservation purposes shall be left in place. The turtle permit holder shall install an on-beach marker at the nest site and a secondary marker at a point as far landward as possible to assure that future location of the nest will be possible should the on- beach marker be lost. A series of stakes and highly visible survey ribbon or string shall be installed to establish a 3-foot radius around the nest. No planting or other activity shall occur within this area nor will any activities be allowed that could result in impacts to the nest. Nest sites shall be inspected daily to assure nest markers remain in place and the nest has not been disturbed by the planting activity; c. If a nest is disturbed or uncovered during planting activity,the contractor, Applicant,or the Applicant's contractors shall cease all work and immediately contact the project turtic`permit holder. If a nest(s)cannot be safely avoided during planting,all activity within 10 feet of a nest shall be delayed until hatching and emerging success monitoring of the nest is completed; d. All dune planting activities shall be conducted by hand and only during daylight hours; e. All dune vegetation shall consist of coastal dune species native to the local area; (i.e.,native to coastal dunes in the respective county and grown from plant stock 115 CAC January 10,2013 VII-8 Staff Report#2 135 of 173 from that region of Florida). Vegetation shall be planted with an appropriate amount of fertilizer and antidesiccant material for the plant size; f. No use of heavy equipment shall occur on the dunes or seaward for planting purposes. A lightweight(all-terrain type)vehicle,with tire pressures of 10 psi or less may be used for this purpose;and g. Irrigation equipment,if needed,shall be authorized under a FDEP permit. Beach Mouse Protection A18. Beach mouse habitat shall be avoided when selecting sites for equipment,pipes,vehicle storage and staging to the maximum extent possible. Suitable beach mouse habitat constitutes the primary dunes(characterized by sea oats and other grasses),secondary dunes(similar to primary dunes,but also frequently includes such plants as woody goldenrod,false rosemary),and interior or scrub dunes, A19. Equipment placement or storage shall be excluded in the area between 5 to 10 feet seaward of the existing dune toe or 10 percent of the beach width (for projects occurring on narrow eroded beach segments)seaward of the dune toe in areas of occupied beach mouse habitat(Figure 16). The toe of the dune is where the slope breaks at the seaward foot of the dune. Toe of Dune Area the pipe can be placed V •O. 5.-i0 feet or 10 percent of Dune total beach width from dune toe Figure 16. Equipment placement for projects occurring in beach mouse occupied habitat. A20. Existing beach access points shall be used for vehicle and equipment beach access to the maximum extent possible. These access points shall be delineated by post and rope or other suitable material to ensure vehicles and equipment transport stay within the access corridor. The access corridors shall be fully restored to the preconstruction conditions following project completion. Parking areas for construction crews shall be located as close as possible to the work sites,but outside of vegetated dune areas to minimize impacts 116 CAC January 10,2013 VII-8 Staff Report#2 136 of 173 to existing habitat and transporting workers along the beachfront. A21. The location of new or expanded existing beach access corridors for vehicles and equipment within beach mouse habitat consisting of vegetated dunes shall be spaced no closer than every four miles. The distribution of access areas will result in the least number of access areas within beach mouse habitat as possible and delineated by post and rope or other suitable material to ensure vehicles and equipment transport stay within the access corridor. The access corridors shall be(1)no more than 25 feet wide for vehicles and (2) no more than 50 feet wide for equipment. Expanded or new beach access points that impact vegetated dunes shall be restored within 3 months following project completion. Habitat restoration shall consist of restoring the dune to preconstruction conditions with planting of at least three species of appropriate native dune vegetation(i.e.,native to coastal dunes in the respective county and grown from plant stock from that region of Florida). Seedlings shall be at least one inch square with a 2.5-inch pot. Planting shall be on 18-inch centers throughout the created dune;however,24-inch centers may be acceptable depending on the area to be planted. Vegetation shall be planted with an appropriate amount of fertilizer and antidesiccant material,as appropriate,for the plant size. No sand stabilizer material(coconut matting or other material)shall be used in the dune restoration. The plants may be watered without installing an irrigation system. In order for the restoration to be considered successful,80 percent of the total planted vegetation shall be documented to survive six months following planting of vegetation. If the habitat restoration is unsuccessful,the area shall be replanted following coordination with the Service. Reporting A22. An excel sheet with the information listed in Table 19 shall be submitted to the Service (Table 3)by July 31 of the following year of construction. The excel sheet shall be available on the Service's website.

In the event a sea turtle nest is excavated during construction activities,the project turtle permit holder responsible for egg relocation for the project shall be notified immediately so the eggs can be moved to a suitable relocation site. Upon locating a dead or injured sea turtle adult,hatchling,egg,or beach mouse that may have been harmed or destroyed as a direct or indirect result of the project,the Corps, Applicant,or local sponsor shall be responsible for notifying FWC Wildlife Alert at 1-888- 404-FWCC(3922)and the appropriate Service Field Office immediately(Table 3). Care shall be taken in handling injured sea turtles,eggs or beach mice to ensure effective treatment or disposition,and in handling dead specimens to preserve biological materials in the best possible state for later analysis. REASONABLE AND PRUDENT MEASURES for: B. Projects that are navigation maintenance dredging with beach placement,swash zone placement,and submerged littoral zone placement shall include the following measures: Historically,these sand placement events as a result of a navigation maintenance dredging project with no local sponsor are smaller scaled,conducted at closer time intervals, and the sand often does not remain on the beach for an extended period of time. 131. Conservation Measures included in the Corps' PBA that address protection of nesting sea turtles and beach mice shall be implemented in the Corps federally authorized project or regulated activity. B2. Beach quality sand suitable for sea turtle nesting,successful incubation,and hatchling emergence and beach mouse burrow construction shall be used for sand placement. 1 B3. For dredged material placement on the beach,sand placement shall not occur during the period of peak sea turtle egg laying and egg hatching to reduce the possibility of sea turtle nest burial,crushing of eggs,or nest excavation. In Brevard,Indian River,St. Lucie,Martin, Palm Beach,and Broward Counties,dredged material placement shall not occur from May 1 through October 31. In St. Joseph Peninsula State Park,St.Joseph peninsula,and Cape San Blas in Gulf County,St. George Island in Franklin County,and Manasota Key in Sarasota and Charlotte Counties,dredged material placement shall not occur from June 1 through September 30. In Nassau, Duval, St.Johns,Flagler,Volusia,Miami-Dade,Monroe, Collier, Lee,Charlotte(except Manasota Key),Sarasota(except Manasota Key),Manatee, Hillsborough,Pinellas,Franklin(except St.George Island),Gulf'(except St.Joseph Peninsula State Park,St.Joseph peninsula,and Cape Sand Blas),Bay,Walton,Okaloosa,Santa Rosa, and Escambia Counties,sand placement may occur during the sea turtle nesting season (Table 15 and Table 16). B4. For dredged material placement in the swash zone(at or below the MHWL)or submerged littoral zone,sand placement will be conducted at or below the+3-foot contour. The swash zone is that region between the upper limit of wave run-up(approximately one-foot above MHW)and the lower limit of wave run-out(approximately one-foot below MLW. Material will not be stacked too high that the material is above the water during low tide. 120 CAC January 10,2013 VII-8 Staff Report#2 140 of 173 APPENDIX D WIGGINS PASS MAINTENANCE DREDGING PLANS CAC January 10,2013 VII-8 Staff Report#2 141 of 173 D-1 Wiggins Pass Sediment Quality Assurance/Quality Control Plan CAC January 10,2013 VII-8 Staff Report#2 142 of 173 Wiggins Pass Sediment Quality Assurance/Quality Control Plan DEP PERMIT 0142538-008-JC F " E M1s 'ma..vHa,e law f ,w� ! a° sri�r iy �. a Submitted To: Florida Department of Environmental Protection Bureau of Beaches and Coastal Systems 3900 Commonwealth Boulevard Tallahassee, FL 32399-3000 Prepared for: Collier County Coastal Zone Management W.

The pass connects the Gulf of Mexico and the Cocohatchee River. Approximately 85,000 cubic yards of material will be removed from the pass and interior system to complete the channel maintenance modification and sand bypassing. Suitable spoil will be placed on the downdrift beaches and nearshore area with unsuitable material being transported to an offshore disposal site at the 1996 Borrow Area 6 location. This plan is a classification system for dredged material which will be used to define detail cuts for dredging. The final design using these cuts will be prepared closer to the time of construction. A separate QA/QC plan will be provided for future maintenance dredging. P �¢W *fi es g x" t 4,' a 4,3t r '" "fie "', a1 �;h. �'y . „ y �' � ,r�` z cps.�: n 3 � ��; su'` ....„„A x» j:s+ ' .y 1 ,� a .

The Contractor shall be responsible for providing continual observation and monitoring of the material and work when material placement is occurring on the beach, in the nearshore, in the ebb and flood shoals and in the offshore disposal area. The term "Nearshore"will include the ebb and flood shoals disposal areas. Spoil shall be placed in accordance with FAC 62B-41.007 (j). 1 CAC January 10,2013 VII-8 Staff Report#2 144 of 173 PROJECT DESCRIPTION The proposed project is based on the results of modeling,engineering,and minimizing dredging of unsuitable material and is summarized below. Refinements may be developed during the final design based on agency and local comments or desires. It accomplishes improved navigation and sediment management by a combination of straightening the channel, major and small maintenance dredging, and new sand disposal practices, as illustrated in Figure 1 above and Table 1. The 10-year plan proposed to achieve the project goals is summarized below: 1) Initial construction of straightened channel i) Dredge compatible sand from ebb channel —41,000 c.y. (Range of 24,000 to 58,000 c.y.) ii) Dredge flood channel—36,400 c.y. iii) Dredge incompatible material—7,500 c.y. iv) Build beach, nearshore, ebb shoal and scour repair with compatible sand—38,200 c.y. v) Fill meander with compatible sand—39,200 c.y. vi) Offshore borrow pit disposal of unsuitable sand- 7,500 c.y. 2) Major maintenance dredging — 50,000 c.y. every 4 years with disposal balanced to favor adjacent Gulf shoreline with greatest need based on equalizing volumetric changes. i) Place beach compatible sand in beach, nearshore or ebb shoal. 3) Intermediate ebb channel dredging as needed i) Excavate and clear ebb channel at the bar and laterally place about 8,000 to 10,000 c.y. in the north ebb shoal to promote regrowth. Beach fill and scarp repair (on beach disposal) at Barefoot Beach is contingent based on clarification of land use and management plans. Fill may also be placed onshore or nearshore at Delnor Wiggins Pass State Park. Material dredged from the ebb shoal and transition channel will be primarily used for these areas. Intermediate and small scale dredging to clear the channel at the bypassing bar and pumping dredge material to an area approximately 300-1000 feet north of the inlet(ebb shoal disposal area) would serve three purposes. Clearing the channel and feeding the re-growth of the ebb shoal are two of these purposes. If dredging could be conducted using smaller equipment during the calmer times of the year, it would also be very economical. In order to minimize project dredging,some natural migration of the channel will be allowed The ebb channel will be allowed to migrate up to 50 feet north and south, except at the gap in the hardbottom. The flood channel will be allowed to migrate up to 50 feet north. Dredging centered on the channel location at the time of dredging to the maximum extent practical will reduce dredging volumes. 2 CAC January 10,2013 VII-8 Staff Report#2 145 of 173 Table 1 Wiggins Pass Vertical and Horizontal Limits Depth Bottom (ft, Overdredge Station Location Width (ft) NAVD) (ft) 15+00 Ebb Shoal 240 -12.0 1.0 0+00 Ebb Shoal 160 -12.0 1.0 C6 Throat 160 -7.7 1.0 C10 Flood Shoal 130 -7.7 1.0 C15 Flood Shoal 130 -7.7 1.0 C26 East Channel 82 -7.0 1.0 C31 South Channel 123 -7.2 1.0 C35 North Channel 70 -7.0 1.0 (1)The Maximum Dredge Elevation includes a 1-foot vertical tolerance BELOW the design elevation(overdredge). No payment shall be made for material excavated below this elevation. (2)The Contractor shall be provided a 1-foot vertical tolerance ABOVE the threshold elevation as a transitional layer between material designated for beach or nearshore placement and material designated for upland or offshore disposal. DESCRIPTION OF WORK The dredge footprint will be divided into subareas based on the quality of sediment,the authorized dredge depth, and the sediment disposal location. Four(4) subareas have been identified and can be identified in Figures 1 to 4 and Table 2. Overlapping dredge areas are regions where dredge material differs laterally. Subarea A: Ebb Shoal without rock Station 4+00 to 15+00 Subarea B: Ebb shoal with rock/rubble substrate Station 0+00 to 4+00 Subarea C: Transition region with clay, peat or silty material Station 0+00 to C-3 Subarea D: Flood shoal Station C-3 to C-16 Subarea E: Tributary areas with clay or silt Station C-17 to C-35. The order of dredging will be D first and E last, and suitable material before unsuitable. Suitable material in Subarea D and E will be used to fill the meander channel. All the material in Subarea A may be placed directly on the beach and supplement filling the meander flood channel. The other subareas contain a mixture of material in which some is eligible for beach or nearshore placement and some must be disposed offshore. The suitable material in Subareas B-E may be placed in the nearshore region or flood shoal. The unsuitable material encompasses approximately 7,500 c.y. and is defined by the Unified Soil Classification System (USCS) as clay, peat or gravel/rock fragment. 3 CAC January 10,2013 VII-8 Staff Report#2 146 of 173 Table 2 Dredged Material Description EBB SHOAL _\.< t .

The Contractor shall be allowed to begin work in multiple subareas and to alternate between subareas, after area D is completed. However, once the Owner's Representative authorizes removal of the unsuitable material from within a specified subarea, no additional material from within the specified subarea shall be allowed for beach or nearshore placement. Table 2 indicates the designated subareas and volumes of material estimated for each respective placement location. Pre-construction surveys shall be used to update actual project volumes. Material designated for beach, nearshore, ebb and flood shoal placement (Figure 1) may be pumped directly to the respective placement site. The material designated for offshore disposal shall be placed in a barge for transporting to the offshore disposal site at Borrow Area 6(Figures 5 and 6).The alternative disposal means is upland.The material designated for upland disposal shall be placed in a containment area for dewatering prior to transporting to the upland disposal site. The upland site is not designated. Since the goal is to use the offshore disposal primarily for unsuitable material, no details will be provided for upland disposal. A threshold elevation is identified for each subarea that contains clay, peat, higher silty sand or rock material. The Contractor shall be provided tolerance above the threshold elevation for excavating material for beach or nearshore placement. The tolerance shall serve as a transition layer (overdredge allowance) between the material designated for beach or nearshore placement and the material that must be disposed as unsuitable material. The threshold elevation shall serve as a definitive line between the unsuitable material and the tolerance. The Contractor shall make all reasonable attempts and precautions to remove the suitable material above the threshold elevation for beach and nearshore placement. Surveys, confirming all the material above the tolerance has been removed, shall be provided by the Contractor prior to removal of any material below the threshold elevation. The threshold elevations are provided in Table 2. ORDER OF WORK Dredging shall commence first in the interior waters of Wiggins Pass. Subarea D shall be dredged first and prior to the dredging of the seaward subareas. Within Subarea D, the coarse top layer will be dredged first, and then the remaining sand suitable for flood shoal disposal. All material designated for offshore disposal shall be disposed in an approved offshore site. The flood shoal holding area(Figure 2) is designed to facilitate transfer of material between the old and new flood channel. Figure 3 shows the lateral cuts. Figure 4 maps the unsuitable material by type and shows the threshold elevation for each area containing unsuitable material. 5 CAC January 10,2013 VII-8 Staff Report#2 148 of 173 w 6- 'A v,,yr - it ~ , r Y • '&+ , ; l*,4,,1 -a ti, - i !

Mechanical dredging may be suitable for rock removal as a supplement, or as approved by the engineer. During all dredging operations, the Contractor shall maintain electronic positioning equipment to continuously monitor the vertical and horizontal location of the cutterhead or sediment intake location. Measurements, or fixes, shall be taken with a maximum lag time of three (3) minutes between readings. The horizontal accuracy shall be a minimum of sub-meter and the vertical shall be+/-0.5 feet. The Contractor shall be responsible for using sufficient equipment and for conducting the work as necessary to insure that the allowable excavation depths and spatial limits are not exceeded. The Contractor shall submit the positioning data on a daily basis in accordance with the following: • In spreadsheet format compatible with Microsoft Excel; • Named in a fashion reflective of the reporting period; • Referenced to NAD83 Florida State Plane West and NAVD88; • Time stamped with the hour and minute of collection with intervals of no more than 3 minutes between records; • No more than one (1)continuous 24-hour period on any one (1) digital file; • Vertical accuracy of+/- 0.5 feet with continuous applicable tidal corrections measured at the project site; and • Horizontal accuracy of sub-meter. The Owner's Representative shall review the positioning data and report any violation to the Contractor and FDEP when they occur. The Contractor shall provide written explanations for any deviations and corrective actions proposed to prevent reoccurrences. Corrective actions shall be taken immediately upon discovery of a potential deviation. If the Contractor encounters unsuitable material for beach or nearshore placement during dredging of an area designated for beach or nearshore placement,the dredge operation shall cease and notify the County immediately if raising the dredge head does not correct the problem. The Contractor shall note the occurrence in the daily reports. Adjustments to the threshold elevation shall be made by the Owner's Representative to avoid placing non-compatible material on the beach or nearshore. Payment for removal and disposal of any additional material requiring disposal offshore, as determined by the Owner's Representative, shall be made in accordance with the Bid Schedule. A full report listing all deviations and unanticipated encounters with unsuitable material shall be provided to the Department upon completion of the work. The report shall contain a detailed listing of all occurrences and the corrective actions taken. The date, location, extent of deviation, and the duration of event shall be provided in the report. The Permittee and Contractor shall comply with all other requirements as specified in Appendix A. 9 CAC January 10,2013 VII-8 Staff Report#2 152 of 173 CRITERIA FOR DISPOSAL LOCATION Spoil shall be placed in accordance with FAC 62B-41.007(j). Material with up to 5% fines by weight, as defined by passing the#230 sieve, shall be placed directly on the beach or within the flood channel meander. Material with more than 5%but less than 10% fines by weight will be placed in the nearshore region of the placement area or in the ebb shoal disposal area. Material that composites at less than 5%silt will be treated as that value. Material with clay or excessive fine content shall be disposed in an upland site or offshore disposal area. All debris and cleared vegetation shall be disposed in the upland site. Based on the November 2011 Geophysical and Geotechnical Review, most of the materials within the cut region is sand with less than 10% silt, and much of the silt content over 5%will composite with the other layers in a core to a silt contents much less than 10%to the desired cut depth. Vibracores with descriptions for clay, peat, silt or other component types with trace and little amounts generally correspond with the silt content of that layer, and will be treated accordingly. In general, all the sediments are sand or shell with less than 10%silt, except those defined as clay, peat or rock(hard substrate),or a fewer high silt content. All sandy, shelly or shell material in the flood shoal with less that 5%silt will be placed in the flood shoal meander.Most layers with higher silt content are thin. This includes shelly material with greater than 5% larger than the#4 sieve. Material with less than 5%and 10%silt will be placed in the ebb shoal or nearshore disposal areas adjacent to the Gulf beaches. Material with 5%greater than the#4 sieve in the ebb shoal and transition region will be assumed to be rock useless clearly identified as shell. All shelly material is natural to the flood shoal, and is essential for stability of the newly created flood shoal, and will be disposed of in the flood shoal. The Contractor shall dispose of all materials not meeting the specifications for beach or nearshore placement in an approved offshore or upland disposal site. The material shall be surface dry during transportation by vehicular means (dump truck). DRESSING OF THE BEACH AND NEARSHORE Immediately following placement of material on the beach, the Contractor shall grade, level, and dress the beach fill to meet the required elevations and dimensions indicated on the plans and specifications. The dressing shall include the removal of humps,depressions, undrained pockets, and all other foreign materials. Material placed in the nearshore disposal area will not need grading. 10 CAC January 10,2013 VII-8 Staff Report#2 153 of 173 TABLE 3 PLACEMENT SPECIFICATIONS Placement Placement Criteria Sediment Characteristic Location Beach D< 5%by Weight Passing 230 Sieve Sand #Quantities Clay, Peat, Organics, Wood = Trace Nearshore or *D < 10% by Weight Passing 230 Sieve Sand Ebb Shoal #Quantities Clay, Peat, Organics= Little Flood Meander D <5%by Weight Retained on 4 Sieve Sand or Shell D> 5%by Weight Retained on 4 Sieve Shell D> 3/4" Similar to native flood shoal Coarse Shell proportions. *D< 10%by Weight Passing 230 Sieve Sand or Shell Offshore Disposal or D> 5%by Weight Retained on 4 Sieve Rock/gravel/pebbles Upland *D> 10%by Weight Passing 230 Sieve Sand Peat, Clay or Organic Clay>20%= Some Sand Peat, Clay or Organic Clay non-sand or shell Note: * During initial construction, material between 5%and 10% silt will be placed in the nearshore or ebb shoal and not the Flood Shoal. #Generally trace and little quantities in sand from the VC log descriptions contain amounts similar to the silt content, and will be treated as such. AUTHORIZATION TO DREDGE CLAY MATERIAL After confirmation by survey that all of the material above the threshold elevation and the tolerance has been removed for any given subarea,the Owner's Representative will authorize the Contractor to begin removal of the clay material or rock for the respective subarea. The material shall be discharged directly into a containment area for dewatering or a barge for transport to the offshore disposal area. VERIFICATION OF FINES AND GRAVEL CONCENTRATION ON THE BEACH The Owner's Representative shall conduct sampling of material placed on the beach to verify no unauthorized disposal occurs. Samples shall be taken during construction and post-construction. During construction samples shall be collected by the Owner's Representative during placement 11 CAC January 10,2013 VII-8 Staff Report#2 154 of 173 operations. A minimum of 1 sample per day shall be collected along profile lines spaced every 500 feet. The samples shall be taken from 6 to 12 inches below the surface. The samples will be visually inspected with a notation of the quality of material noted in the daily report. The samples shall be archived with the date,time,and location obtained noted. If the placement specifications do not appear to be satisfied, a sieve analysis will be conducted to determine silt content and/or gravel. (Shell or shell fragments present in the sample shall not require a sieve analysis for gravel content) A copy of all sieve analysis reports shall be included in the post construction report. The Permittee and Contractor shall comply with all other requirements as specified in Appendix A Section D.7. Post-construction samples shall consist of one (1) sample collected along profile lines spaced every 500 feet. The samples shall be taken after the Contractor has graded the beach and from 6 to 12 inches below the surface. The location, date and time of the sample collection will be archived by the Owner's Representative.The Permittee and Contractor shall comply with all other requirements as specified in Appendix A Section D.8. If material is placed offshore, a sample will be taken for each 5,000 cy placed in the disposal area. A sieve analysis will be conducted on the post construction samples by Collier County. The location of any sample exceeding 10%by weight passing the#230 sieve or 5%by weight retained in the#4 sieve shall be marked and additional collections will be made to the north, south,east and west at approximately 20 foot increments. A sieve analysis shall be conducted on these samples and the process shall continue until the boundary of excess fine or gravel material is determined. Copies of all sieve analysis reports shall be included in the post construction report. If the fine content exceeds 5% for any area greater than 1,000 square feet on the dry beach, but is below 10%,the material shall be mechanically placed in the nearshore or mixed with surrounding material. If the material is mixed and the average fine content is still greater than 5%,the material shall be removed and placed in the nearshore. If the fine content is greater than 10%for any 1,000 square foot area after mixing,the fines shall be removed from the beach and placed at an approved upland facility or offshore location. Additional testing shall be conducted post remediation to confirm the fine content is below 10%by weight for the material left on the beach. The standard for nearshore disposal will be 10%, but only additional samples with testing will be required. If gravel content is 5% or greater for any dry beach area, the FDEP shall be consulted regarding remediation techniques consisting of the following: • mixing the material with surrounding material, or • removal of the gravel content and disposal at an approved upland facility. Additional testing shall be conducted post remediation to confirm the gravel content is less than 5% by weight in the#4 sieve. The constructed beach shall be smooth graded to remove all ruts, depressions and indentions after 12 CAC January 10,2013 VII-8 Staff Report#2 155 of 173 the fine content is confirmed to be less than 5%by weight and the gravel content is less than 5%. No grading will be required if sand is not directly placed on the beach. VERIFICATION OF NO CLAY PLACEMENT IN THE NEARSHORE Construction techniques do not adequately allow for the removal of clay or peat material once placed in the nearshore. Additional precautions shall be implemented during construction to prohibit clay material from being placed in the nearshore as follows: • The Owner's Representative shall make visual observations of the material as it is placed on a minimum average of 15 minutes every 2 hours, or directly sample the disposal area during the next day after night operations. • If the Owner's Representative determines clay is present, the disposal material shall be diverted to a containment area for upland placement or barge for offshore placement. Nearshore disposal shall not resume until the clay is determined absent from the material. • The Owner's Representative shall collect two (2) grab samples from within 50 feet of the discharge location and in the nearshore zone, each day after the discharge advances. The samples shall be visually assessed for clay content. Summaries of the findings shall be included in daily reports and summarized in the post construction report. If clay is determined to have been placed in the nearshore, the County shall conduct remedial activities as discussed with the DEP. NON COMPLIANCE MEASURES The County shall reserve the right to issue a Stop Work order if at any time the Contractor fails to conduct the operations in accordance with the plans and specifications. No additional payment shall be made for the Contractor's stand-by time during the Stop Work order. The Order shall remain in effect until such time the Contractor assures the County all Quality Control measures are being, and shall continue to be implemented. The Permittee and Contractor shall comply with all other requirements as specified in Appendix A Section E. REPORTING The Owner's Representative shall prepare weekly summaries detailing the results of the Quality Assurance activities. The summaries shall be available to all project stakeholders and interested parties. Copies of all tests, analysis, reports of non-compliance and corrective actions implemented shall be included in the post construction report and furnished to the FDEP. The Permittee and Contractor shall comply with all other requirements as specified in Appendix A Section E. 13 CAC January 10,2013 VII-8 Staff Report#2 156 of 173 HANDLING PLAN The following information is provided to supplement the Wiggins Pass Sediment Quality Assurance/Quality Control (QA/QC) Plan to provide specific information regarding the governing specifications for the handling and disposal of the unsuitable beach material. TRANSPORTING MATERIALS TO THE OFFSHORE DISPOSAL SITE The Contractor shall ensure all vessels and equipment used to transport material to the offshore disposal site are properly maintained. Material shall be secured within the vessels and shall not be allowed to have substantive leaks while in Outstanding Florida Waters or in route to the disposal site. The materials shall be maintained by the Contractor until disposal at the offshore site. No discharged water used for dredging unsuitable material shall be discharged into Outstanding Florida Waters (OFW). Discharge activity (pipeline) shall be at least 100 meter outside of OFW or at the offshore disposal area. The location of the offshore disposal area is shown in Figures 5 and 6. Disposal or dumping into the borrow pit shall be within the target area shown in Figure 6. The Contractor shall be responsible for any material disposed of outside the limits of Borrow Area 6.

Since this project includes dredging of new areas in addition to previously dredged areas,the beach sand standard has been directed. A different plan document will be used for inlet excavation involving beach or nearshore placement of maintenance dredged material. Pursuant to Fla. Admin. Code r. 62B-41.008 (1)(k)4.b.,permit applications for inlet excavation,beach restoration, or nourishment shall include a quality control/assurance plan that will ensure that the sediment from the borrow areas to be used in the project will meet the standard in Fla.Admin.Code r. 62B-41.007(2)(j). To protect the environmental functions of Florida's beaches, only beach compatible fill shall be placed on the beach or in any associated dune system. Beach compatible fill is material that maintains the general character and functionality of the material occurring on the beach and in the adjacent dune and coastal system. The Permittee has conducted geotechnical investigations that provide adequate data concerning the character of the sediment and the quantities available within the spatial limits of the permitted borrow area(s). The Permittee has provided an analysis of the existing or native sediment and the sediment within the permitted borrow area(s) that demonstrates its compatibility with the naturally occurring beach sediment in accordance with Fla.Admin.Code r.62B-41.007(2)(j). The sediment analysis and volume calculations were performed using established industry standards,and are certified by a Professional Engineer or a Professional Geologist registered in the State of Florida. Based upon this information and the design of the borrow area(s), the Department of Environmental Protection (Department) has determined that use of the sediment from the borrow area(s) will maintain the general character and functionality of the sediment occurring on the beach and in the adjacent dune and coastal system. Furthermore, this information and the borrow area design provides sufficient quality control/quality assurance (QC/QA)that the mean grain size and carbonate content of the sediment from the borrow area(s) will meet the requirements of Fla.Admin.Code r.62B-41.007(2)(j); hence, additional QC/QA procedures are not required for these sediment parameters during construction. This plan outlines the responsibilities of each stakeholder in the project as they relate to the placement of beach compatible material on the beach.These responsibilities are in response to the possibility that non-beach compatible sediments may exist within the borrow area(s) and could be unintentionally placed on the beach. The QC Plan specifies the minimum construction management, inspection and reporting requirements placed on the Marine Dredging Contractor and enforced by the Permittee,to ensure that the sediment from the borrow area(s)to be used in the project meet the compliance specifications. The QA Plan specifies the minimum construction oversight, inspection and reporting requirements to be undertaken by the Permittee or the Permittee's On-Site Representative to observe,sample,and test the placed sediments to verify the sediments are in compliance. B.SEDIMENT QUALITY SPECIFICATIONS The sediment from the borrow area(s) is similar in Munsell color and grain size distribution to the material in the existing coastal system at the beach placement site. The Department and the Permittee acknowledge that it is possible that discrete occurrences of non-beach compatible sediments may exist within the permitted borrow area(s) that do not comply with the limiting parameters of Fla.Admin.Code r.62B-41.007(2)(j) 1.—5.,or vary in Munsell Page 1 of 6 CAC January 10,2013 VII-8 Staff Report#2 161 of 173 color from the composite value. Furthermore,the Department may consider more restrictive values for the sediment parameters to ensure that the sediment from the borrow area(s) is similar in color and grain size distribution to the sediment in the existing coastal system at the beach placement site. Therefore, fill material compliance specifications for the sediment from the borrow area(s)proposed for this project are provided in Table 1. The compliance specifications take into account the variability of sediment on the native or existing beach, and are values which may reasonably be attained given what is known about the borrow area sediment. Beach fill material which falls outside of these limits will be considered unacceptable and subject to remediation. Table 1-Sediment Compliance Specifications Sediment Parameter Parameter Definition Compliance Value Max.Onshore Silt Content passing#230 sieve 5% Max.Nearshore Silt Content passing#230 sieve 10% Max.Shell Content* retained on#4 sieve n/a Munsell Color Value moist Value(chroma= 1) 4 or lighter The beach fill material shall not contain construction debris,toxic material,other foreign matter, coarse gravel or rocks. *Shell Content is used as the indicator of fine gravel content for the implementation of quality control/quality assurance procedures. C.QUALITY CONTROL PLAN The contract documents shall incorporate the following technical requirements, or equivalent language that addresses the location of dredging, sediment quality monitoring on the beach, and, if necessary, remedial actions. The Permittee will seek to enforce these contract requirements during the execution of work. 1. Electronic Positioning and Dredge Depth Monitoring Equipment. The Contractor will continuously operate electronic positioning equipment, approved by the Engineer, to monitor the precise positioning of the excavation device location(s) and depth(s). A Differential Global Positioning System (DGPS) or equivalent system providing equal or better accuracy will be used to determine the horizontal position and will be interfaced with an appropriate depth measuring device to determine the vertical position of the bottom of the excavation device. The horizontal positioning equipment will maintain an accuracy of+/-3.0 feet. The vertical positioning equipment will maintain a vertical accuracy of+/-0.5 feet with continuous applicable tidal corrections measured at the project site. 2. Dredge Location Control.The Contractor is required to have, in continuous operation on the dredge,electronic positioning equipment that will accurately compute and plot the position of the dredge. Such fixes, and the accompanying plots,will be furnished to the Permittee's on-site representative daily as part of the QC Reports.The electronic positioning equipment will be installed on the dredge so as to monitor, as closely as possible,the actual location of the excavation device(s).The location of the master antenna on the dredge and the distance and direction from the master antenna to the bottom of the excavation device will be reported on the Daily Reports. A printout of the excavation device positions in State Plane Coordinates,the excavation device depths corrected for tide elevation and referenced to the North American Vertical Datum of 1988(NAVD 88)and the time,will be maintained using an interval of two(2)minutes for each printed fix.A printed and computer file(in ASCII format)copy of the position data will be provided to the Engineer as part of the daily report. The Contractor will prepare a plot of the data that includes the State Plane Coordinate grid system and the borrow area limits.The format of the plot may be subject to approval by the Permittee's Engineer.No dredging will take place outside of the borrow area limits(horizontal and vertical limits)as shown on the drawings. 3. Dredging Observation.The Contractor will be responsible for establishing such control as may be necessary to insure that the allowable excavation depths and spatial limits are not exceeded. If the Contractor encounters noncompliant sediment during dredging, the Contractor will immediately cease dredging, relocate the dredge into Page 2 of 6 CAC January 10,2013 VII-8 Staff Report#2 162 of 173 compliant sediment, and will verbally notify the Permittee's On-site Representative, providing the time, location, and description of the noncompliant sediment. The Contractor will also report any encounters with noncompliant sediment in the Contractor's Daily Report,providing depth and location in State Plane Coordinates of said materials within the borrow area. The Contractor, in cooperation with the Permittee's Engineer, will use the dredge positioning records, plans, and vibracore descriptions to determine where the Contractor may dredge to avoid additional placement of noncompliant sediment. The Contractor will adjust his or her construction operation to avoid the noncompliant sediment to the greatest extent practicable. 4. Beach Observation. The Contractor will continuously visually monitor the sediment being placed on the beach. If noncompliant sediment is placed on the beach, the Contractor will immediately cease dredging, relocate the dredge into compliant sediment, and verbally notify the Permittee's On-site Representative, providing the time, location, and description of the noncompliant sediment. The Contractor will also report any encounters with noncompliant sediment in the Contractor's Daily Report,providing depth and location in State Plane Coordinates of said materials within the borrow area. The Contractor will take the appropriate remediation actions as directed by the Permittee or Permittee's Engineer. 5. Excavation Requirements. The Contractor will excavate within the approved boundaries and maximum depths of the borrow area(s) in a uniform and continuous manner. If directed by the Permittee's Engineer,the Contractor will change the location and/or depth of excavation within the borrow area limits. 6. Vibracore Logs and Grain Size Data. The Contractor will be provided with all descriptions of sediment vibracore borings collected within the borrow area(s), and will acknowledge that he is aware of the quality of the sediment as described in the sediment vibracore logs. These logs and grain size data will be presented in the construction specifications. D.QUALITY ASSURANCE PLAN The Permittee will seek to enforce the construction contract and Department permits related to sediment quality. In order to do so,the following steps shall be followed: 1. Construction Observation. Construction observation by the Permittee's On-Site Representative will be performed 7 days a week, at least 8 hours a day during periods of active construction. Most observations will be conducted during daylight hours;however,random nighttime observations shall be conducted. 2. On-Site Representative. The Permittee will provide on-site observation by individuals with training or experience in beach nourishment and construction inspection and testing,and who are knowledgeable of the project design and permit conditions. The project Engineer, a qualified coastal engineer, will actively coordinate with the Permittee's On-Site Representative, who may be an employee or sub-contractor of the Permittee or the Engineer. Communications will take place between the Engineer and the Permittee's On-Site Representative on a daily basis. 3. Pre-Construction Meeting. The project QC/QA Plan will be discussed as a matter of importance at the pre- construction meeting. The Contractor will be required to acknowledge the goals and intent of the above described QC/QA Plan,in writing,prior to commencement of construction. 4. Contractor's Daily Reports. The Engineer will review the Contractor's Daily Reports which characterize the nature of the sediments encountered at the borrow area and placed along the project shoreline with specific reference to moist sand color and the occurrence of rock, rubble, shell, silt or debris that exceeds acceptable limits. The Engineer will review the dredge positions in the Contractor's Daily Report. 5. On Call. The Engineer will be continuously on call during the period of construction for the purpose of making decisions regarding issues that involve QC/QA Plan compliance. 6. Addendums. Any addendum or change order to the Contract between the Permittee and the Contractor will be evaluated to determine whether or not the change in scope will potentially affect the QC\QA Plan. Page 3 of 6 CAC January 10,2013 VII-8 Staff Report#2 163 of 173 7. During Construction Sampling for Visual Inspection.To assure that the fill material placed on the beach is in compliance with the permit, the Permittee's Engineer or On-Site Representative will conduct assessments of the beach fill material as follows: a. During excavation and fill placement activities, the Permittee's On-Site Representative will collect a sediment sample at not less than 200-foot intervals of newly constructed berm to visually assess grain size, Munsell color, shell content, and silt content. The sample shall be a minimum of 1 U.S. pint (approximately 200 grams). This assessment will consist of handling the fill material to ensure that it is predominantly sand to note the physical characteristics and assure the material meets the sediment compliance parameter specified in this Plan. If deemed necessary, quantitative assessments of the sand will be conducted for grain size, silt content, shell content and Munsell color using the methods outlined in section D.8.b. Each sample will be archived with the date,time,and location of the sample. The results of these daily inspections, regardless of the quality of the sediment,will be appended to or notated on the Contractor's Daily Report. All samples will be stored by the Permittee for at least 60 days after project completion. b. If the Permittee or Engineer determines that the beach fill material does not comply with the sediment compliance specifications in this QC/QA Plan, the Permittee or Engineer will immediately instruct the Contractor to cease material excavation operations and take whatever actions necessary to avoid further discharge of noncompliant sediment The Contractor, in cooperation with the Permittee's Engineer,will use the dredge positioning records, plans, and vibracore descriptions to determine where the Contractor may dredge to avoid additional placement of noncompliant sediment. The Contractor will adjust his or her construction operation to avoid the noncompliant sediment to the greatest extent practicable.The sediment inspection results will be reported to the Department. 8. Post-Construction Sampling for Laboratory Testing. To assure that the fill material placed on the beach was adequately assessed by the borrow area investigation and design,the Project Engineer will conduct assessments of the sediment as follows: a. Post-construction sampling of each acceptance section and testing of the fill material will be conducted to verify that the sediment placed on the beach meets the expected criteria/characteristics provided during from the geotechnical investigation and borrow area design process. Upon completion of an acceptance section of constructed beach, the Engineer will collect two (2) duplicate sand samples at each Department reference monument profile line to quantitatively assess the grain size distribution,moist Munsell color,shell content,and silt content for compliance. The Engineer will collect the sediment samples of a minimum of 1 U.S. pint (at least 200 grams) each from the bottom of a test hole a minimum of 18 inches deep within the limits of the constructed berm. The Engineer will visually assess grain size,Munsell color,shell content,and silt content of the material by handling the fill material to ensure that it is predominantly sand,and further to note the physical characteristics. The Engineer will note the existence of any layering or rocks within the test hole. One sample will be sent for laboratory analysis while the other sample will be archived by the Permittee. All samples and laboratory test results will be labeled with the Project name, FDEP Reference Monument Profile Line designation, State Plane (X,Y) Coordinate location, date sample was obtained, and "Construction Berm Sample." b. All samples will be evaluated for visual attributes (Munsell color and shell content), sieved in accordance with the applicable sections of ASTM D422-63 (Standard Test Method for Particle-Size Analysis of Soils), ASTM D1140 (Standard Test Method for Amount of Material in Soils Finer than No. 200 Sieve), and ASTM D2487(Classification of Soils for Engineering Purposes),and analyzed for carbonate content.The samples will be sieved using the following U.S. Standard Sieve Numbers: 3/4", 5/8",3.5,4, 5, 7, 10, 14, 18,25,35,45,60, 80, 120, 170,and 230. c. A summary table of the sediment samples and test results for the sediment compliance parameters shall accompany the complete set of laboratory testing results. The column headings will include: Sample Number; Mean Grain Size (mm); Sorting Value: Silt Content (%); Shell Content (%); Munsell Color Value; and a column stating whether each sample MET or FAILED the compliance values found in Table 1 The sediment testing results will be certified by a P.E or P.G.registered in the State of Florida. A statement of how the placed fill material compares to the sediment analysis and volume calculations from the sand search investigation and Page 4 of 6 CAC January 10,2013 VII-8 Staff Report#2 164 of 173 borrow area design shall be included in the sediment testing results report. The Permittee will submit sediment testing results and analysis report to the Department within 90 days following beach construction. d. In the event that a section of beach contains fill material that is not in compliance with the sediment compliance specifications, then the Department will be notified. Notification will indicate the volume, aerial extent and location of any unacceptable beach areas and remediation planned. E.REMEDIATION 1. Compliance Area. If a sample does not meet the compliance value for construction debris,toxic material, other foreign material, coarse gravel, or rock the Permittee shall determine the aerial extent and remediate regardless of the extent of the noncompliant material. If a sample is noncompliant for the silt content, shell content, or Munsell color and the aerial extent exceeds 10,000 square feet,the Permittee shall remediate. 2. Notification. If an area of newly constructed beach does not meet the sediment compliance specifications, then the Department (JCPCompliance @dep.state.fl.us) will be notified. Notification will indicate the aerial extent and location of any areas of noncompliant beach fill material and remediation planned. As outlined in section E.4 below, the Permittee will immediately undertake remediation actions without additional approvals from the Department. The results of any remediation will be reported to the Department following completion of the remediation activities and shall indicate the volume of noncompliant fill material removed and replaced. 3. Sampling to determine extent. In order to determine if an area greater than 10,000 square feet of beach fill is noncompliant,the following procedure will be performed by the Engineer: a. Upon determination that the first sediment sample is noncompliant, at minimum, five (5) additional sediment samples will be collected at a 25-foot spacing in all directions and assessed. If the additional samples are also noncompliant, then additional samples will be collected at a 25-foot spacing in all directions until the aerial extent is identified. b. The samples will be visually compared to the acceptable sand criteria. If deemed necessary by the Engineer, quantitative assessments of the sand will be conducted for grain size, silt content, shell content, and Munsell color using the methods outlined in section D.8.b. Samples will be archived by the Permittee. c. A site map will be prepared depicting the location of all samples and the boundaries of all areas of noncompliant fill. d. The total square footage will be determined. e. The site map and analysis will be included in the Contractor's Daily Report. 4. Actions.The Permittee or Permittee's Engineer shall have the authority to determine whether the material placed on the beach is compliant or noncompliant. If placement of noncompliant material occurs, the Contractor will be directed by the Permittee or Permittee's Engineer on the necessary corrective actions. Should a situation arise during construction that cannot be corrected by the remediation methods described within this QC/QA Plan, the Department will be notified. The remediation actions for each sediment parameter are as follows: a. Silt: blending the noncompliant fill material with compliant fill material within the adjacent construction berm sufficiently to meet the compliance value,or removing the noncompliant fill material and replacing it with compliant fill material. b. Shell: blending the noncompliant fill material with compliant fill material within the adjacent construction berm sufficiently to meet the compliance value or removing the noncompliant fill material and replacing it with compliant fill material. c. Munsell color: blending the noncompliant fill material with compliant fill material within the adjacent construction berm sufficiently to meet the compliance value or removing the noncompliant fill material and replacing it with compliant fill material. d. Coarse gravel: screening and removing the noncompliant fill material and replacing it with compliant fill material. e. Construction debris,toxic material,or other foreign matter:removing the noncompliant fill material and replacing it with compliant fill material. Page 5 of 6 CAC January 10,2013 VII-8 Staff Report#2 165 of 173 All noncompliant fill material removed from the beach will be transported to an appropriate upland disposal facility located landward of the Coastal Construction Control Line. 5. Post-Remediation Testing. Re-sampling shall be conducted following any remediation actions in accordance with the following protocols: a.Within the boundaries of the remediation actions,samples will be taken at maximum of 25-foot spacing. b. The samples will be visually compared to the acceptable sand criteria. If deemed necessary by the Engineer, quantitative assessments of the sand will be conducted for grain size, silt content, and Munsell color using the methods outlined in section D.8.b. Samples will be archived by the Permittee. c. A site map will be prepared depicting the location of all samples and the boundaries of all areas of remediation actions. 6.Reporting.A post-remediation report containing the site map,sediment analysis,and volume of noncompliant fill material removed and replaced will be submitted to the Department within 7 days following completion of remediation activities. All reports or notices relating to this permit shall be emailed and sent to the Department at the following locations: DEP Bureau of Beaches&Coastal Systems JCP Compliance Officer Mail Station 300 3900 Commonwealth Boulevard Tallahassee,Florida 32399-3000 phone:(850)414-7716 e-mail:JCP Co npliance @dep.state.fl.us End of Plan FDEP Version dated September 4,2009 Page 6 of 6 CAC January 10,2013 VII-8 Staff Report#2 166 of 173 D-2 Physical Monitoring Plan CAC January 10,2013 VII-8 Staff Report#2 167 of 173 Attachment No.37 Physical Monitoring Plan Wiggins Pass Channel Straightening with Erosion Mitigation June 2012 A plan to monitor the performance of the channel dredging, to identify potential erosion and accretion patterns along the adjacent shoreline, to verify the analysis that were conducted in the development of the design of the project, and to identify any adverse impacts, which would be attributable to the project authorized by this permit is summarized in this document. The monitoring will also be used to support future permitting of the project. The channel cross-sections to be surveyed are depicted in Figure 1 and coordinates are listed in sheet 2 of the permit sketches. The control required to survey the channel and adjacent shorelines is summarized in the survey report of the annual monitoring or as part of the Engineering Monitoring Report. The surveys will be conducted annually during the month that construction was completed in the most recent dredging event year or the anniversary of the post- construction survey, whichever is later. The survey and engineering monitoring reports should be completed within 90 day after completion of the topographic and hydrographic surveys. The monitoring plan is subject to modification at the direction of the department (FDEP) should shoreline conditions change. 1. The topographic and hydrographic monitoring program shall include the following: a. Beach and offshore profile surveys shall be conducted within 90 days prior to project commencement, within 60 days following completion of the project, and annually thereafter until the next maintenance dredging. The monitoring survey shall be conducted as close as possible during that same month of the year. If the time period between the immediate post-construction survey and the first annual monitoring survey is less than six months, a postponement of the first monitoring survey until the following spring/summer may be requested. The request should be submitted as part of the cover letter for the post-construction report. A prior design or monitoring survey of the beach and offshore may be submitted for the pre-construction survey if consistent with the other requirements of this condition. A waiver may be requested for conducting an annual monitoring survey after previous monitoring surveys demonstrate inlet and shoreline stability, and navigation reports and site inspections indicate no significant channel shoaling or shoreline erosion since the previous monitoring survey. Profiles shall be surveyed at DEP reference monuments R-10 through R-21. Additional profile lines shall be surveyed at intermediate locations approximately midway between reference monuments to accurately identify patterns and volumes of erosion and accretion within this subarea. Their specific location will be selected with the first survey conducted with this plan. The profile alignments will be identical to the azimuths previously established for each monument. All beach profiles shall extend from the monument at least 2000 feet seaward and out CAC January 10,2013 VII-8 Staff Report#2 168 of 173 to the depth of closure if greater. In all other aspects, work and activities shall be consistent with the BBCS Monitoring Standards for Beach Erosion Control Projects, Sections 01000 and 01100. b. Bathymetric surveys of the Wiggins Pass navigation channel and adjacent areas shall be conducted within 90 days prior to project commencement, within 60 days following completion of the project, and annually thereafter until the next maintenance dredging at Stations -2+00 to +15+00 and C-3 to C-35. The profiles and stations are shown on the permit sketches and in Figure 1 above. The bathymetric surveys shall extend a minimum of 100 feet beyond the boundaries of the entire ebb shoal complex (R-15 to R-18.5). The cross-sections shall cover as a minimum the dredge and fill limits from the initial project. The monitoring survey shall be conducted as close as possible during that same month of the year. Post-construction monitoring surveys will be decreased for future maintenance dredging to only cross-sections that were dredged plus three (3) additional cross- sections along the east-west axis. In all other aspects, work and activities shall be consistent with the BBCS Monitoring Standards for Beach Erosion Control Projects, Section 01200. c. Specific attention will be paid to assessing the performance of the Wiggins Pass Gulf shoreline north of R-17 and along the inlet interior using historic and recent aerial photographs. The assessment will be included in Item 4 below. A MHW survey will extend from R-17 approximately 1500 feet north and east along the sandy shoreline. 2. Controlled Aerial Photography Controlled Aerial photograph shall be provided by the County from any of their departments or contracting with a firm to fly them to FDEP standards. Aerial photography will be provided concurrently with the post-construction survey and each monitoring survey. The aerial photography shall be done as close to the date of the beach profile survey as possible. The limits of aerial photography shall include the surveyed area described above. 3. Current and Tide Measurements A survey of the currents and tides using an ADCP type instrument in Wiggins Pass will also be performed at the one-year post-construction survey. Measurements will be taken over a span of two weeks within the main channel and north, south, and east tributary channels. The measurements shall be taken at survey cross-sections. These cross-sections may be in addition to those described in Section 1-b. CAC January 10,2013 VII-8 Staff Report#2 169 of 173 4. Report a. The permittee shall submit an engineering report summarizing the monitoring data and project performance to the Bureau of Beaches and Coastal Systems within 90 days of completion of each survey. The report shall summarize and discuss the data, the performance of the project, and identify erosion and accretion patterns within the monitored area. In addition, the report shall include a comparative review of project performance to performance expectations and identification of impacts attributable to the project. Appendices shall include plots of survey profiles and graphical representations of volumetric and shoreline position changes for the monitoring area. Results shall be analyzed for patterns, trends, or changes between annual surveys and cumulatively since project construction. b. Two paper copies and one electronic copy of the monitoring report, and one electronic copy of the survey data shall be submitted to the Bureau of Beach and Coastal Systems. \IC170 All 58 0 Jsf at1 an7ffu3aRr ye p1 00r,t 2402 1 3 , ---z•.--- z:, .1-1 ='.

We are bidding truck haul as an option and I am meeting with hauler over the next several week to explore the best ways to make this happen. The County Manager has directed that we share the preliminary facts and concepts with you to get your thoughts and ideas. Obviously,this is a work in progress but this is how we see the situation at this time. 1. We are looking at a renourishment timeline from 11/1/2013 to 4/1/2014. Turtle season actually starts officially on 5/1 but I am cutting it short because of early nesting and also a security cushion encase the project runs longer. This timeframe represents 5 months of productive renourishment. 2. We might be able to stretch the renourishment time by working on the shoulders of nesting season by starting on 9/15 and completing on 6/1 but that cannot be guaranteed at this time and is not popular with members of the community. 3. This is the busiest time of the year for visitors and tourists but staying out of turtle nesting season dictates this schedule. 4. Based on a preliminary design of a 420,000 Cy renourishment: Vanderbilt beach would receive 57,000 Cy's; Park shore would receive 112,851 Cy's and Naples would receive 230,149 Cy's of material. 5. The average road truck can haul 22.5 Tons of material per trip. At 1.38 tons per Cy,that equates to 16.3 CY's per truck. I checked these figures with our recent emergency truck haul project and they were verified. 6. Doing the math,Vanderbilt Beach would require 3,500 trucks and has one truck access point at Vanderbilt Beach Road. There is no other access for this beach segment. All the road vehicles would need to unload at the end of Vanderbilt Beach Road and the off road vehicles would need to be loaded at this same location. I would expect that this beach access point would need to be closed down for the 5 months of this operation at this location. 7. Park Shore would require about 6,925 truckloads of sand. The City has access at Horizon Way (R-52),Via Miramar (R56) and Veldado Way. The unloading operation can be CAC January 10,2013 VII-9 Staff Reports 2 of 4 improved if mat is laid between two of the locations to allow the road trucks to enter at one location; run on the mat and exit at a second location. 8. Naples Beach would require 14,200 trucks to renourish this segment. It would require at least two offloading locations. With some help from the City and assurance of repairs, access locations can be established at the Moorings private beach; Lowdermilk Park;8th or 7th Ave North (none exist at either of these locations now); 3rd Ave North; and possibly a location like 9th Ave South. No sand is contemplated south of here. 9. Maintenance of traffic would be critical and a continual challenge. Truck only lanes on the arterial roadways should be considered to relieve congestion. Some level of road damage should be anticipated. 10. The most truck we were able to unload in one "sunup to sundown" day was 120 vehicles from the Immokalee mine which is the closest. Sunup to sundown is contemplated for this operation. 11, Off-road truck traveling along the beach is a safety issue. We would require at least two escort vehicles, usually gators per off road vehicle. 12. Each unloading location would require continuous truck sampling and inventory control. 13. The mines cannot usually separate the sand in rainy weather. Stockpiling separated sand would be critical considering the Immokalee can only produce approximately 5,000 CY's per day and the Deltona mine 10,0000 CY's per day in good weather. 14. More than one mine would be needed to supply material for this project. At least two mines,the Immokalee Stewart mine and the Deltona mine are qualified and have been permitted by FDEP in the past. Even with all these challenges,the bottom line is that Collier County can work out the logistics to make truck haul happen if directed to do so. The County staff would need to work extremely close with your staff to make this happen. However,the City of Naples would experience approximately 20,000 round trip truck deliveries during a 5 month period between November 2013 and April 2014 (40,000 trucks if you consider each way trips). Congestion would occur on arterial roadways as well as at unloading locations. Access locations would need to be closed to the public. Some road damage would occur and our maintenance of traffic would be a monumental effort. I would like the City to comments and input to these preliminary thoughts. We plan on taking this back to the BCC on 1/22/13 but would like your comments and suggestions as soon as possible. Call me when you get back from holiday and we can talk this through.

Staff will be taking an outline of the specification parameters for this project to the BCC on January 8,2013,followed shortly thereafter by the bid solicitation for the project. The county Commission has asked staff to develop several bid alternates,including a truck hauling alternate using an inland sand source. Staff anticipates that this alternative would result in a significant volume of truck traffic along the roads in the City of Naples. If the City has a formal position on the alternative, it would be very helpful to know before the 8th so staff may communicate same to our Board when they are considering these alternatives. Gary McAlpin can provide an estimate of the number of trucks required to complete the renourishment in the City using this method. Please let me know the City's position on this matter at your earliest convenience. Happy Holidays! Leo E.

Periodic renourishment has been a fundamental component of the most desired attributes in Collier County, and the condition of the beach is appreciated by permanent residents and visitors alike. We have closely followed the development of the planned renourishment project for 2013, and we once again look forward to completion of this project which, we believe, is essential for the continuing improvement in our local economy and the quality of life for our citizens. We have learned that there may be serious consideration for a renourishment project that may haul beach-compatible sand from an inland source. If such a strategy is pursued, thousands of truck trips required to deliver the sand to the beach from the Immokalee area and/or central Florida will cause significant disruptions to the residents of Collier County and the City of Naples. We respectfully advise that the Naples City Council is adamantly opposed to a truck-haul option (except for emergency "hot spot" renourishment) and encourage the Board of Commissioners to follow the common and historical practice of hydraulically pumping sand to the beaches from off-shore locations. When considering the details of a trucking alternative, the numbers and potential impacts are staggering. It is estimated that approximately 40,000 truck trips to and from mines will be needed to deliver over 342,000 cubic yards of sand to Naples' beaches alone. Each truck is expected to weigh over 35 tons when 64r' ir/44. .zF.x . (xeii4 ira i�f�/4/, ?r .i 1 CAC January 10,2013 VII-10 Staff Reports 2 of 2 loaded with sand. While State and County arterials may be designed to handle such loading, residential City streets are not. The condition and expected useful life of local streets, including street ends used for beach access, would be greatly diminished by this type of use. At this time, City staff is currently evaluating some evidence of pavement damage along the route taken by trucks for the recent emergency renourishment activity near the Naples Beach Hotel, even with the relatively small quantity of sand that was hauled to this beach location. Furthermore, the anticipated traffic congestion along the truck route is expected to significantly disrupt the roadway level of service. Residents living along the truck route would be exposed to truck noise, dust and exhaust. Lastly, but most importantly, the operation of large trucks along the beach would impact the safety of beachgoers while shutting down large portions of the beach and beach-end streets for long periods of time when recreational access is most needed for the enjoyment of visitors and residents. In summary, the Naples City Council supports a renourishment project that continues to follow operational practices that have been used by the County during prior large-scale renourishment activities. The City supports hydraulically pumping sand to the beach from an offshore location. The City does not support a truck haul alternative for a project of this size and scale. Thank you for considering our opinion, and we look forward to working with you for the completion of a successful beach renourishment project. /7-1— John F.
