The level of restoration will be determined during final design and compliment sand bypassed from the Wiggins Pass dredging project. The restoration project will used approximately 250,000 cubic yards to restore the shoreline and the adjacent ebb shoal. Based on modeling, beach placement closer to the inlet will have the greatest impact toward restoring Barefoot Beach. The disposal shape will be determined by modeling and complimentary engineering and design studies. Past disposal practices placed dredged material where it creates a sediment deficit within a'A mile north of the inlet's vicinity. Project Location: The Barefoot Beach Restoration Project is located on the southwest Florida coastline in Collier County between Florida Department of Environmental Protection monuments R -14 and R -16.3, downdrift and adjacent to Wiggins Pass. The project consists of approximately 0.45 miles of critically eroded Gulf shoreline. Use of Requested Program Funds: Funds requested for FY11 /12 will be used for final design and construction.

Additional Rankine Criteria Will this project enhance or increase the longevity of a previously- constructed project? Yes Will this project nourish a previously restored shoreline? No Rate of Erosion as determined by the Bureau based on long term data (ft/yr) 6.16.1 ft/yr Severity of erosion: The entire portion of the project area has been designated by FDEP as critically eroded. The area near R16 is currently experiencing the most severe erosion rate in the project area, losing an average of 13.9 ft/yr or 418 feet since 1978. The second largest erosion within the project area occurred directly north at R15. This area has lost 143 feet of shoreline at a rate of -4.8 feet per year since 1978. The erosion rate for the total project area is approximately 6.1 feet per year 16D 13 Agenda Item No. 16D13 December 14, 2010 Page 8 of 39 Collier County Long Range Budget Plan FY 11/12 — Barefoot Beach Restoration Project over a 30 year time period. The stable condition of R14 to the north has helped to reduce the shoreline erosion rate within the project area. Project Benefits: Shoreline development within the project area consists of approximately 2,360 linear feet of publicly accessible beach. The entire portion of the project area is recreational and habitat. The attached maps identify public beach access points with associated parking spaces within the project area. Gopher tortoises utilize the entire project area for nesting purposes although none of the areas within the project area have been designated as a turtle refuge. The nourishment will initiate restoration of lost habitat. Periodic dredging and bypassing has taken place at Wiggins Pass in recent decades. The total volume of sand bypassed to adjacent beaches from maintenance dredging has been 498,650 cubic yards since 1984. Approximately 260,937 cubic yards of that fill has been placed to the north, with the remaining 237,713 cubic yards being placed to the south of the inlet. This project will fill the gap where sand is not spreading naturally and supplement the bypassing operations and will replace deficits started in the 1980s, which will mitigate for past inlet impacts. Use of Innovative Applications of existing technologies: Geographic computer modeling will be utilized to identify the most beneficial region to place the restoration fill. A multi -stage recovery will be implemented in order to restore the eroding shoreline along with restoring the ebb shoal in order to alleviate erosion at Barefoot Beach, without severe impacts to navigation. Nourishment Interval (years): Project Performance: 6 The shorelines near Wiggins Pass have been eroding at an accelerated rate since the 1990s, which directly affects the amount of recreational area available to the public. During the period from 1992 to 2009, the largest shoreline retreat was observed at R -16 with over 400 feet of shoreline lost. Approximately 10 acres has been lost from the Gulf beaches since 1992. The shoreline recession on South Barefoot Beach has caused vegetation to be lost, and it has also created a dangerous scarp along the shoreline that is hazardous to park users. Along with the loss of vegetation, walking paths that were present in 1973 at Barefoot Beach have been eroded away and are no longer present in several areas to the west and south. In comparison to the shoreline changes, the volumetric changes also indicate that the shoreline north of Wiggins Pass is trending to become highly erosional. From 1885 to 1979, the shoreline north of Wiggins Pass was overall accreational for approximately 100 years. After 1979 to present, the shoreline shifted and is now in a state of erosion. The worst of the erosion is seen at R -16 where approximately 201,000 cubic yards have been lost. This erosion has caused the southern tip of South Barefoot Beach to nearly shear off, which in return has lost valuable recreational area and habitat within the park. Agenda IterfTl h X1313 December 14, 2010 Page 9 of 39 Collier County Long Range Budget Plan FY 11/12 — Barefoot Beach Restoration Project The restoration is scheduled for FY 2012/2013, but may need to be flexible to agency desires and the schedule for Wiggins Pass. As such, it is not tied to one of these projects. Is this project being planned or constructed in cooperation with another local government? Explain? Yes This project will be built to compliment the Wiggins Pass Inlet Management Plan and the Collier County Nourishment Project, where feasible. Monitoring of all Collier County Coastal projects is consolidated for economy — including both physical and biological monitoring and the sea turtle nesting program. The two coastal cities and county share this effort.

The 2005/06 re- nourishment project consisted of the restoration, using approximately 665,000 cubic yards of hydraulic fill, and maintenance of up to eight miles of Gulf of Mexico shoreline along unincorporated Collier County and the City of Naples. This project was completed in May 2006 with the main goal to avoid environmental impacts such as hard -bottom coverage and a design project life of six to eight years. The borrow area was located just over 33 miles north - northwest of Vanderbilt Beach and was chosen due to the coarser sand availability which will generally avoid near -shore hard -bottom coverage. A one acre artificial reef was constructed to satisfy mitigation permit requirements. In 1995/1996 much of the same project area was hydraulically re- nourished. Approximately 240,000 cubic yards of upland sand was placed for maintenance and another 160,000 cubic yards of sand was bypassed since this major re- nourishment project. The renourishment in 2012 -2013 will be approximately 500,000 cubic yards and will include a new area, Clam Bay Park within the Park Shore Segment. The project will reach its six year design life in 2012/13 and hot spot nourishment in required. Project Location: The City of Naples /Collier County Beach Renourishment Project is located on the southwest Florida coastline in Collier County between Florida Department of Environmental Protection monuments R -22 and R -79. The project consists of approximately 5 miles of critically eroded Gulf shoreline. Use of Requested Program Funds: Funds requested for FYI 1/12 will be used for annual physical monitoring, biological monitoring, and turtle monitoring activities associated with the 2006 construction and design and permitting tasks in preparation of the upcoming renourishment in FY 12/13. The renourishment in FY 12/13 will be approximately 500,000 cubic yards. 1 Agenda Item No. 16D1 December 14, 2010 Page 13 of 39 Collier County Long Range Budget Plan FY 11/12 — Collier County Beach Renourishment Local Government Suonort Does this sponsor have dedicated support staff whose sole priority is to manage beach erosion control activities?

Additional Rankine Criteria Will this project enhance or increase the longevity of a previously- constructed project? Yes Will this project nourish a previously restored shoreline? Yes Rate of Erosion as determined by the Bureau based on long term data (ft /yr) 4.5 ft/vr Severity of Erosion: A majority of the project area has been designated by FDEP as critically eroded. The Naples Beach area is currently experiencing the most severe erosion rate in the project area, losing an average of 6.4 ft/yr since June 2006. The Vanderbilt Beach and Pelican Bay project areas have been eroding at a rate of 5.0 feet per year since construction of the 2006 project. The Park Shore project area has eroded 5.4 feet since June 2006. Erosion within the total project area has averaged 4.5 ft/yr since 1996. Threat to Upland Structures: Based upon a similar modeling study within the region, 41 structures are threatened due to recession from the 25 -year storm. 16013 Agenda Item No. 16D13 December 14, 2010 Page 16 of 39 Collier County Long Range Budget Plan FY 11/12 — Collier County Beach Renourishment Project Benefits: Shoreline development within the project area consists of over 29,000 linear feet of publicly accessible beach. 7,230 linear feet (85 %) of the Vanderbilt Beach property is commercial or recreational. This includes four hotels, Delnor - Wiggins State Park and Collier County's Vanderbilt Beach Road Park. 3,725 linear feet (29.26 %) of the Park Shore property is zoned commercial or recreational and eligible. Another 2,300 feet is Clam Pass Park, but although this area is erosional, it is not designated as critically eroded. This includes three public access streets (City of Naples). 18,410 linear feet (95.02 %) of the Naples Beach property is zoned commercial or recreational. This includes the City of Naples' Lowdermilk Park, two hotels and numerous public access streets and walkways. The attached maps identify public beach access points, hotels, and other commercial facilities within the project area. Threatened and endangered marine turtles utilize the entire project area for nesting purposes although none of the areas within the project area have been designated as a seaturtle refuge. Periodic dredging and bypassing has taken place at Wiggins Pass, Clam Pass, Doctors Pass and Gordon Pass in recent decades. The total volume of sand bypassed to adjacent beaches from the four inlets since completion of the 1996 project is estimated at approximately 600,000 cubic yards. Use of Innovative Applications of Existing Technologies: Current technologies in practice will be used for the upcoming renourishment project and subsequent monitorings. In addition, an investigation to improve hot spot performance and tune structures using modeling is planned. Sand performance has met expectations, and beach widening is feasible without significant threat to nearshore hardbottom. Nourishment Interval (years): 6 -8 Project Performance: The project was built between January 23, 2006 to May 23, 2006, with dredging starting on February 21, 2006. Collier County's 8.5 miles of renourished shorelines include Vanderbilt Beach, Pelican Bay, North Park Shore, Park Shore, and Naples Beach. These beaches were renourished with an as -built sand volume of approximately 667,562 cubic yards of sand during construction. The project was constructed by Great Lakes Dredge & Dock Company (GLDD) with two hopper dredges, the Sugar Island and the Manhattan Island. Dredge and fill operations lasted a total of 92 days. All of the project areas were renourished with sand from the Borrow Area T -1, which is located approximately 33 miles northwest of Delnor- Wiggins State Park. Volumetric changes measured from the pre - construction November 2005 survey to the three year post- construction July 2009 survey measured 529,278 cubic yards remaining in the project area or 80% of the design volume. It appears that the shorelines are still recovering from the active 2004 -5 and 2008 storm season where Tropical Storm Fay affected the project area. The next full nourishment is scheduled for FY 2012/2013 at the planned 6 -year renourishment interval.

All the monitoring activities are required by the FDEP permit. Marco Beach was restored in early winter 2007 using approximately 180,000 cubic yards of hydraulic fill along with the maintenance of 4,500 feet of Gulf of Mexico shoreline along the City of Marco Island. The project area was previously renourished in 1997. The same borrow area from the 1997 project was used for the 2007 project, which was completed in March 2007. The design project life for the recent nourishment is between six to eight years. Project Location: The South Marco Island Beach Renourishment Project is located on the southwest Florida coastline of Collier County between Florida Department of Environmental Protection monuments R -142 and beyond R -148 to the terminal groin. The project is being designed for the next nourishment with consideration for improving the existing structures. Use of Requested Program Funds: Funds requested for FYI 1/12 will be used for annual physical monitoring and turtle monitoring activities associated with the 2007 construction, and design for the next nourishment.

Additional Rankine Criteria Will this project enhance or increase the longevity of a previously- constructed project? Yes Will this project nourish a previously restored shoreline? Yes Rate of Erosion as determined by the Bureau based on long term data (ftlyr) 3.1 ft/vr Severity of Erosion: A majority of the project area has been designated by FDEP as critically eroded. Marco Beach is currently eroding at a rate of -11.7 feet per year since January 2007. Project Benefits: 2,740 linear feet (41.76 %) of the Marco Island Beach property is zoned commercial or recreational. This includes two hotels /resort condos and a public access point with parking across the street. Periodic dredging has taken place at Caxambas Pass. The total volume of sand dredged and hydraulically pumped to the adjacent beach from Caxambas Pass since 1990 is estimated at 800,000 cubic yards. Though Collier County has no federally designated sea turtle refuges, loggerhead sea turtles nest throughout the county, and this project will enhance those opportunities. Beach tilling will directly support turtle nesting by decreasing beach sand compaction.

Nourishment Interval (years): 6 -8 Project Performance: Beach fill material was dredged from Caxambas Pass and placed between FDEP R- monuments R -145 to R -148. Overall, approximately 176,000 cubic yards of sand were placed onto the beaches of South Marco Island. The project area has about 109 feet, or 75 %, of beach width remaining since construction. Since construction, the shoreline has lost approximately 36 feet of shoreline, which is equivalent to a rate of -11.9 feet per year. The project area has retained its construction volume; however, the profiles at the southern end of the project area have eroded while the profiles in the northern section of the project area have accreted. Is this project being planned or constructed in cooperation with another local government? Explain? Yes Collier County and the City of Marco Island are jointly sponsoring this project. The project combines beach nourishment with inlet dredging. All county monitoring, including the two cities, is combined for economy.

This will be accomplished by straightening the inlet channel layout and modifying bypassing. The designated dredge disposal locations and quantities will be modified and relocated to increase management flexibility, reduce sediment loss to the system and impacts to Barefoot Beach shoreline. A dynamic design will be incorporated into the maintenance plan for the inlet so that long -term dredging can be reduced. Impacts to natural resources will be avoided or minimized. The goals for the Wiggins Pass navigation improvement study as developed by Collier County and the Wiggins Pass Modeling Evaluation Work Group are: 1. To provide a safe channel for boating 2. To address erosion at Barefoot Beach 3. To lengthen the dredge cycle and accomplish it with the least effect on the environment 4. To provide a solution that is economically effective The project will be implemented in four phases. The phases include initial construction (Figure 1), major maintenance dredging, intermediate ebb channel dredging and monitoring, mitigation and contingency plans. A Barefoot Beach restoration project is separate and will not be included in this request. It will supplement bypassing proposed in this project. Figure 1. Phase I of Construction Agenda Item No. 16D13 December 14, 2010 Page 32 of 39 Collier County Long Range Budget Plan FY 11/12 — Wiggins Pass Inlet Management Plan Implementation There are five game changing facts recognized since the current plan for Wiggins Pass was formulated in the 1990's that will be connected by the new plan: 1. The flood channel is migrating north significantly 2. Net alongshore transport is to the north 3. Insufficient bypassing is occurring to the north 4. The inlet and flood shoal are infilling from the south by a reoccurring sand wave 5. The rock ledge/ hard substrate extends to both sides of the channel These facts are the basis for the new design proposed in Wiggins Pass Engineering Reports (Feb 2010), submitted as Attachment 33a of the JCP permit. An inlet management plan with modeling and permit application is currently in progress. The modeling studies (CPE 2009) indicate that improved navigation conditions and mitigation of erosion on adjacent beaches can be achieved by redesigning the navigation channel and modifying the placement location and quantity of the dredged material. The total initial cut volume estimate is 80,000 CY (Figure 1) and it will provide a prolonged maintenance interval. The maintenance will include major maintenance dredging of approximately 45,000 CY each 4 years along with intermediate ebb (surgical) channel dredging of approximately 6,000 CY as needed. This restoration will provide additional sand for bypassing to Barefoot Beach, mitigating the historic erosion problem in this area. Periodic bypassing to Delnor Wiggins State Park will be part of the plan. A nourishment of Barefoot Beach is being considered as a separate project to restore the shoreline and adjacent ebb shoal with a one time nourishment of 250,000 CY, supplementing this plan. This project will help restore the sediment deficit to the north. Project Location: The Wiggins Pass Project is located on the southwest Florida coastline in Collier County between Florida Department of Environmental Protection monuments R16 and R17 and the project is adjacent to approximately 2300 feet of critically eroded Gulf shoreline. Use of Reauested Program Funds: Funds requested for FYI 1 /12 will be used for final design and initial construction of the project.

Increased nourishment interval estimated for down drift beach: 1 point per year with maximum of 5 points. 2.0 Points Project Benefits: The project will attempt to reestablish the historic shoreline and the ebb shoal size. Also, Gopher tortoises utilize Barefoot Beach for nesting purposes although none of the areas within the project area have been designated as a turtle refuge. Periodic dredging and bypassing has taken place at Wiggins Pass in recent decades. The total volume of sand bypassed to adjacent beaches from maintenance dredging has been 498,650 cubic yards since 1984. Approximately 260,937 cubic yards of that fill has been placed to the north, with the remaining 237,713 cubic yards being placed to the south of the inlet. The ratio needs to be shifted to approximately 2.6:1 in favor of the north. Use of Innovative Applications of existing technologies: Maintain natural alignment after implementation and use of intermediate (surgical) dredge events to delay major dredge events. Dredging Interval (years): 4 Project Performance: , Wiggins Pass was designed to be dredged at regular intervals of approximately 3 to 4 years but is currently dredged at regular intervals of approximately 2 years or less to maintain navigable depths for recreational boaters. The dredge channel extends from the inlet throat to about 1,200 feet offshore. Periodic dredging has occurred at the intersection of the interior channels. The inlet has been dredged since 1984 under two previous permits, secured by the County with a local consultant. Since maintenance dredging began in 1984, the overall erosion has increased along with the magnitude of erosion experienced at beaches to the north. Intially, the beaches to the south were erosional through the early 1990s. Since 1992, the shoreline north of the inlet at Barefoot Beach has retreated on average approximately 87 feet. The worst area of erosion is occurring at R16, where, since 1992, it has lost approximately 437 feet of shoreline. Overall, it appears that the current maintenance dredging practices are not properly addressing the northern losses at Barefoot Beach nor the stability of the dredged channel. Historic reports indicated that sediment transport was from north to south, and erosion was higher south of the inlet between 1957 and 1979. However, the recent volumetric data contrasts with that belief. From 1979 to 2009, the area north of Wiggins Pass (R11 to R 16) eroded 252,926 cubic yards, while the area south of the inlet has accreted 49,603 cubic yards. Prior to 1979, before maintenance dredging, the erosion accretion pattern was reversed, with the north accretional. Agend;.0 1 13 December 14, 2010 Page 37 of 39 Collier County Long Range Budget Plan FY 11/12 — Wiggins Pass Inlet Management Plan Implementation Using these values along with the historic shoreline changes, it appears that more sand needs to be disposed of.at the north during maintenance dredging to reduce erosion on Barefoot Beach. The amount of dredge disposal north and south of the inlet has been nearly equal since dredging began in 1984. Lately, the trend is towards north disposal since 2001. An analysis was made to calculate the disposal balance needed to make each area have an equal erosion rate. As an example, the areas south of the inlet (R17 to R21) showed a gain of almost 50,000 CY since 1979, while the area north of the inlet (RI l to R16) lost 253,000 CY. To equalize the rate of volumetric change in these areas since 1979, disposal volumes should have been 2.7 times greater to the north (Barefoot Beach Park) than the south (Delnor Wiggins Park). This is a major shift over past practices. Ultimately, this bypassing ratio should equalize stability of the shoreline north and south of the inlet. Navigation will be improved by straightening the channel through the flood and ebb shoal, reducing the need for dredging. Boaters have difficulty finding the channel in the S -shape natural alignment. The S -shape is caused by a long term natural process. Human engineering factors are needed for improved channel design.
