APPROVAL OF MAY 14 AND MAY 23 MEETING MINUTES Mr. Cravens motioned,Dr. Chicurel seconded to approve t ,a and ", t4 23 meeting minutes as presented. The Committee voted unanimous!_ + 1 ., Ilion passed. r 23 Clam Bay Committee Meeting Minutes June 26,2013 DEVELOPMENT OF CLAM BAY MANAGEMENT PLAN Mr. Hall described the purpose of the management plan as a document to provide guidance to the community by identifying and outlining goals, objectives, scope of activities, and form the basis for future permitting that would provide agency authorization to do the activities outlined in the Plan. For example,the Plan would identify dredging"triggers",parameters, and scope of work. When the Plan indicates it is time to dredge, authorization to dredge would be sought. ESTIMATE OF COSTS Mr. Hall estimated it would cost approximately$200,000 in total to develop the management plan. Approximately$100,000 includes annual monitoring and reporting contract services the firm already provides. Surveys, engineering services, document compilation, surveys, meetings, and permitting services would cost an estimated$100,000 in total. TIMELINE FOR FIRST DRAFT OF PLAN Mr. Hall estimated the timeline was approximately six months to prepare the management plan and an additional six months for permitting, or longer depending upon whether the County Purchasing Department requires the project to go through the Request for Proposals(RFP)process. To clarify the timeline, Mr. Dorrill and Ms. O'Brien would schedule a meeting with the County Purchasing director and Clerk's Finance director to find out whether an RFP will be required and provide a report at the July Board meeting. WATER QUALITY COMPILING AVAILABLE DATA FROM COUNTY AND PBSD Ms. O'Brien reviewed water quality data from STORET and explained the Services Division may want to consider having water quality data from other sources compiled and analyzed. MISCELLANEOUS Mr. Hall reported that permitting for the Osprey nest box can be done under the Foundation's existing permit located near the South Beach facility. Mr. Dorrill reported two issues of importance: 1) a child nearly drowned last week at C . 'ass and reports blamed the recent dredging was too narrow as the cause. For liability purposes e that the proper signage was in place at the Pass to warn swimmers; and 2)May 5, several hu high school students congregated at Clam Pass. Underage drinking and other unla vity d and reported to the Sheriff and County Parks and Recreation staff to not allow this tire.

Adjourn -ItiV - f•26 Clam Bay Committee Meeting Minutes July 16,2013 ROLL CALL All Committee members were present. BOARD OF COUNTY COMMISSIONERS DOCUMENTS PERTAINING TO APPROVAL OF WORK ORDER TO UPDATE THE CLAM BAY MANAGEMENT PLAN Chairman O'Brien reviewed the backup material of the chronology of Board of County Commissioners action regarding approval of the work order to update the Clam Bay Management Plan. The material was originally prepared for the discussion with the Clerk of Courts and Purchasing staff regarding how to proceed in terms of the procurement process to update the Clam Bay Management Plan. AVAILABLE RESOURCES FOR UPDATE OF CLAM BAY MANAGEMENT PLAN Ms. Kathy Worley observed that the available resources listed to update the management plan were primarily for mangrove or hydrologic restoration and suggested looking at other plans that were more pertinent to managing an estuary system. The Committee discussed topics to include in the draft plan. Some agreed that it was imperative to include dredging"triggers"and parameters; others agreed information about dredging could be added later after the draft was complete. Mr. Dorrill stressed that it was imperative to include dredging designs, parameters, and dredging "triggers" in the Plan. Mr. Hall agreed and was concerned about how to proceed with the Stakeholders input received. The Committee agreed that the applicable parts of the 2008 Draft Clam Bay Mangrove Management Plan,the 1998 Restoration and Management Plan and the stakeholder input would serve as the basis for updating the Clam Bay Management Plan. Dr. Chicurel suggested"Clam Bay Natural Resource Protection Area NRPA Management Plan" as the title of the plan. TIMELINE FOR UPDATED CLAM BAY MANAGEMENT PLAN Mr. Hall would prepare a draft plan for the Committee's review by September 1 and determ.,1 estimated expenses-to-date and additional costs. SCIENTIFIC SERVICES FOR PELICAN BAY SERVICES DIVISION(ADD-ON) Chairman O'Brien suggested that Committee members think about whether the PB s consider hiring a staff scientist. The Committee was concerned about locating canw ith t required education and experience,and the cost an additional full-time employee. , VIY 'on deferred to the next Committee meeting.

Discuss Draft Clam Bay Management Plan(Comments by Joe Chicurel) Page 1 of 11 t THE CLAM BAY NATURAL RESOURCE PROTECTION AREA MANAGEMENT PLAN (First DRAFT) Tim, I'd like to give you some suggestions to include in your drafting of the 2013 Clam Bay(NRPA) Management Plan. Your clarification to us that a management plan is for our stewardship of Clam Bay helped us better focus on the task at hand. I think, however, that it is also a historical document that catalogs the chronologic history of the geography(boundaries),development,science(flora and fauna-mangroves of course),engineering data, uses,governence, and the environmental concerns and issues of the Clam Bay system. After reading the 1998 CBRMP and the 2006/2008 drafts plans, it seems that all had similar ingredients. Our new 2013 plan should incorporate and build on the other plans. I believe the new 10 year plan should not only help our stewardship but also lay out to all stakeholders an unambiguous history of the science and engineering data of the Clam Bay NRPA.All stakeholders will then have a core knowledge base that can hopefully help eliminate or lessen differences of opinion as issues arise concerning Clam Bay NRPA usage,dredging, permitting,etc. I'll use your 2013 Table of Contents as a blueprint for my suggestions. The body of the 2008 draft looks like a good template and I followed it with my suggestions. Thank you for your good work and expertise.

This plan will form the basis by which future management decisions can be made by identifying the appropriate management techniques necessary to preserve, enhance, restore, maintain and monitor the uses and resources within the Natural Resource Protection Area. The plan will attempt to balance resource protection with passive recreational use. It will consider Clam Pass monitoring and maintenance, restoration needs, water quality, listed species protection, education and other issues as identified in the Plan's formulation process. The final management plan and any subsequent revisions shall be submitted to the Collier County Board of County Commissioners (BOCC) for its approval. When approved, this plan will form the basis for future permitting and other management activities within the system. Overview of the Clam Bay System The Clam Bay estuarine system is a 570-acre area of sandy beaches, shallow bays, seagrass beds and mangrove forests on the coast of Collier County in southwest Florida. The community of Pelican Bay abuts the northern and eastern edges of the system, while the Seagate and Naples Cay communities abut the southern portion of the system. This system is an important natural and recreational resource for local residents and visitors. It was designated a Natural Resource Protection Area(NRPA) by Collier County in 1994. This plan, in addition to providing a brief history of activities undertaken within this system, outlines management goals, objectives and methods to achieve optimal functioning of the delicate mangrove system. Drawing on an earlier plan (The Clam Bay Restoration and Management Plan prepared by the firm of Wilson Miller Barton& Peek, CBRMP 1998), and the findings of 14 years of monitoring activities within the system, this plan outlines the goals for future enhancements to, and maintenance of, the ecosystems throughout Clam Bay. The Clam Bay Restoration and Management Plan, 1998 In 1992 a small area of dead black mangroves was first observed in the northern part of the system. In 1995 a significant area (approximately 50 acres) of dead and dying mangroves was reported (Turrell, 1996). Following the die-off, restorative dredging was proposed to increase tidal flushing by opening up the pass and widening several tidal creeks within the system. The CBRMP was prepared in conjunction with State and Federal environmental permits to carry out the work, and consequently focused on management objectives which were proposed at that time, namely; CLAM PASS NRPA MANAGEMENT PLAN(DRAFT) Pelican Bay Services Division September 3, 2013 • Deepening and maintaining Clam Pass • Dredging portions of the interior tidal creeks to improve flushing capacity • Studying the potential for improvements in upland stormwater/freshwater management • Installation of flushing culverts under Seagate Drive The Clam Pass Natural Resource Protection Area Management Plan, 2013 This Clam Pass Natural Resource Protection Area Management Plan (CPMP, 2013) combines the comprehensive outline and background provided in the original 1998 plan with lessons learned during and subsequent to its implementation. The goals of this Plan will be to direct the management activities undertaken to enhance the estuarine and associated habitats in a manner that maintains and contributes to the overall integrity of the Clam Bay ecosystem. Namely, the activities undertaken under the Plan will: • Provide sufficient tidal exchange to maximize benefits to the estuary • Maintain and protect native floral and faunal communities • Improve water quality while maintaining the stormwater discharge and surface water management necessary to support the adjacent communities • Address recreational uses within the system with emphasis on passive recreation • Continue to educate and inform residents and visitors about the importance of the ecosystem Personnel/Consultants Responsible This CPMP has been prepared by the firm of Tunell, Hall & Associates, Inc., who, as project managers for the restorative dredging and associated monitoring work has a long history with the project and ecosystem. Input and monitoring data has been incorporated from coastal engineers, Humiston & Moore, Inc., as well as other interested stakeholders such as the Pelican Bay Foundation, the Mangrove Action group, the Conservancy of Southwest Florida, adjacent community associations, and the City of Naples. The ongoing support and assistance of the PBSD and Collier County is gratefully acknowledged.

Pelican Bay Services Division September 3, 2013 Pelican Bay Services Division In order for the management and enhancement of the Clam Pass NRPA to be successful, coordination between a myriad of local, state, and federal agencies and concerned citizen's groups is required. The Pelican Bay Services Division (PBSD) has undertaken that role for most of the past fifteen years. The PBSD is a dependent special district known as the Pelican Bay Municipal Services Taxing and Benefit Unit. It was formed pursuant to Chapter 125 of the Florida Statutes and was formally enabled by the Collier County Commission pursuant to Ordinance numbers 90-111 and 91-22. These ordinances were replaced in 2002 by Ordinance 2002-27 which further clarified the basis and role of the MSTBU and PBSD Board. This MSTBU was created to, among other things, provide for the maintenance of conservation and preserve areas within Pelican Bay. This responsibility was undertaken diligently from 1998 to 2009 and resulted in the implementation of the previous Management Plan and the recovery of the mangrove die-off area. The Collier County Coastal Zone Management Department assumed responsibility of the Pass monitoring and maintenance for a short while from 2009 to 2012 while the PBSD continued to monitor and maintain the mangrove communities within the system. At the beginning of 2013, the Collier County BOCC returned responsibility of the Pass to PBSD via Ordinance 2013-19 and it is under their direction that this current management plan is being written. As a dependent special district, the PBSD is an arm of local county government and as such does not enjoy the ability to make decisions concerning the implementation of the Management Plan independent of the desires of the Collier County BOCC. The PBSD budget, and therefore its ability to undertake work projects, is controlled by the Collier County BOCC. In practical application, this has not proved problematic, as the BOCC has routinely approved the mangrove management undertakings of the PBSD and the BOCC has authorized the development of this Management Plan. The PBSD implements County policy within the confined geography of the Pelican Bay community and the defined responsibilities of the PBSD. The PBSD sets it own budget and agenda and routinely submits same to the Collier County BOCC for approval. The actual workings of the relationship suggest therefore, that the PBSD has experienced a significant degree of practical autonomy and that this is expected to continue in regards to the implementation of this Management Plan. The result is that the PBSD will be the official manager of this Management Plan with delegated authority to be implemented consistent with Ordinances 2002-27, and 2013-19 of Collier County. The PBSD will direct this Management Plan and have the responsibility for its implementation and operation over time. As such, the PBSD will plan and implement defined management activities (with BOCC approval) whose purpose will be to protect, enhance and maintain the natural communities and ecological integrity of the Clam Bay NRPA. CLAM PASS NRPA MANAGEMENT PLAN(DRAFT) Pelican Bay Services Division September 3, 2013 The PBSD has several attributes which already make it a logical guiding force in the management of Clam Bay. The PBSD: • Is located within the Clam Bay drainage basin; • Has an advisory board(appointed by the County Commission)made up of residential, and business members within Pelican Bay; • Garners fiscal support collected from local benefit assessments; • Is accessible by the public due to its local governing board and advertised public monthly meetings; and • Has demonstrated a long-term commitment to the resource and its preservation and enhancement over the past fifteen years. These attributes give PBSD the knowledge and expertise in matters of local concern and, in particular, the problems, opportunities and interests of local residents as they relate to the Clam Bay ecosystem. Its relationship to the BOCC give it an additional level of access to technical expertise and oversight that will be necessary to assure that the Management Plan, as contemplated in this document, is fully implemented in the field. As part of its responsibilities, the PBSD will assemble and distribute various technical reports and assessments as required under the Management Plan, as well as coordinate with the other public and private groups interested in Clam Bay. The PBSD is organized for and designed to maintain both its knowledge of the Clam Bay resources and to generate public support for the same. PBSD will insure that the general public, residents in Pelican Bay, PBSD consultants, and representatives from government agencies with jurisdiction over Clam Bay each have on-going involvement and input into the Management Plan as appropriate. CLAM PASS NRPA MANAGEMENT PLAN(DRAFT) Pelican Bay Services Division September 3, 2013 2.0 Clam Bay Location and Setting Maps, description of Pelican Bay and the estuary system Clam Bay was designated a Natural Resource Protection Area by the Board of County Commissioners of Collier County in 1994 (Collier County, 1994) and consists of approximately 420 acres of mangroves and some 115 acres of shallow, open water bays, as well as a 35 acre beachfront parcel (Clam Pass Beach Park). The system consists of three primary bays; Outer Clam Bay (southernmost), Inner Clam Bay (central), and Upper Clam Bay (northernmost), connected by a series of tidal creeks. 4 ,. ti v \ v rt+ cc Ott t i,,f r . r"..� { _f+ '�°' �z_y�r--fir '�'.�� t. 3.Fa.i �„iS�iti..+ 4 '�4 Ey eF 1%.17.,-N- .. c -., �y %' i ;, . - t tk, .:%.,... .r i F ., j , "..�:: ♦ e n 7 ' r r- .xar_t ` L� Mget ' r a$ .4.s :' i( cr far � f j�l+mda aA,g ♦ �.i � `�� +� Sfe"� � �� qg g �+p ,?....%.r 1T'Q ,- .'t fit, ;4,40-i 4 te,41,r r 9.t$/�4* , ".„. , Sv F _` IT .a. . 0-j%:.x10 , el�'. *;y....*: "i, *:$` /W TI' i *j' 7 t , i t C� 1 ': L�fi Ca ty aIG.* �kIZV'' 4 CCU i {� f'. l ,'ri „t lE': . ��.. f+.,.. a-:r.+,ate af.'.

Prior to dredging, average water depths were -2.5' to -1.0' with a width of 30-50' (Collier County, 1994). The Pass remains the primary source of tidal exchange for the Clam Bay system, but it is restricted by sediment deposits just inside the pass and in the long meandering tidal creeks surrounded by mangrove forests. The smaller embayments located primarily to the north of the pass are not subject to normal tidal exchange except during exceptionally high tides. Tidal range is restricted throughout the Clam Bay system (Turrell 1995; Collier County Report 1996; Tackney 1996). Tide gauges are installed and monitored on the County boardwalk at the north end of Outer Clam Bay, the north and south Pelican Bay boardwalks, and in Upper Clam Bay. These gauges indicate that the dredging done at the pass and in the interior creeks has drastically improved the tidal exchange throughout the system. Tidal ranges vary from 2 feet out in the Gulf to 1.5 feet in the southern portion of the system down to about 0.5 feet at the northern end of the system. South of Clam Pass, a channel oriented north-south with water depths varying between -1.0' to - 4.0' leads to Outer Clam Bay (approx. 72 acres), itself connecting to the Venetian lagoon system via a couple of concrete culverts under Seagate Drive. There are also three dead end canals off the south end of Outer Clam Bay that are associated with the Seagate community. North of Clam Pass, a long narrow (approximately 6,600') tributary leads to Inner Clam Bay (approx. 32 acres). Evidence in the literature suggests that oyster bars were once present in this channel (Humm and Rehm, 1972). A further,narrow creek(5,400') leads north from Inner Clam Bay to the smallest and most isolated; Upper Clam Bay(approx. 20 acres). Historical aerials and anecdotal recollections from long-time County residents note a connection of the system at Upper Clam Bay to Vanderbilt Lagoon and Wiggins Pass to the north via a small creek (Collier County, 1994, Tropical Biolndustries, 1978). This connection was eventually severed with the development of Vanderbilt Beach Road in the 1950s. The system is bounded on the north by Vanderbilt Beach Road, to the south by Seagate Drive,to the east by the Pelican Bay development and to the west by the Gulf of Mexico. Pelican Bay is predominately a residential community of private single-family homes, as well as both high and low-rise condominium units. The community also includes a 27-hole golf course, common areas with meeting rooms, tennis courts, beach park facilities, emergency services facilities, and commercial areas with shopping and hotels. The 2,104-acre Planned Unit Development (PUD) was approved in 1977 as a partnership between Collier Enterprises and Westinghouse Communities. It was one of the first developments in Florida required to save fragile coastal wetlands and associated ecosystems (Urban Land Institute, 1981). The development of Pelican Bay had a limited impact on the wetlands themselves (approximately 94 acres in total with about 78 of those acres located in the northwestern corner of the property) leaving the mangrove forest intact and preserved around the bays. As mitigation for these wetland impacts, the 35 acre beach park was donated to Collier County.

A four to six foot high and 2 1/2 mile long berm separates the developed portion of Pelican Bay from the estuary lying to the west of the development, but numerous culverts through the berm discharge water to a swale system along the eastern perimeter of Clam Bay. The eastern edge of Pelican Bay is about 12-14 feet above sea level at US 41, sloping in an east-west direction to about 2 feet near the berm. Six drainage basins operate on a gravity system to slowly move surface water into the receiving area of Clam Bay.

CLAM PASS NRPA MANAGEMENT PLAN(DRAFT) - Pelican Bay Services Division September 3,2013 Natural History Prior to development, the entire coastline of south Florida would have resembled the Clam Bay system with meandering mangrove lined waterways buffering sandy barrier islands and terrestrial communities. Unique within the moderately developed coastal community of Collier County, Clam Bay is a valuable resource for wildlife (particularly juvenile marine species and birds) as well as residents and visitors to the area who enjoy the recreational opportunities the system offers such as kayaking, fishing, walking, swimming, bird watching, beach going, and others. The system is a mixture of mangrove-lined tidal creeks,mangrove forests, shallow bays and tidal passes, seagrass beds, tidal flats, sandy beaches and brackish interior wetlands. A man-made water management berm now divides natural and developed portions where historically mangrove forest would have transitioned gradually into the mesic coastal hammocks and upland pine scrubs that made up the now developed portions of the Pelican Bay community. A brief overview of these important habitat types, their key characteristics and value is provided in the Resource Description Section of this Plan. Pass History - Historically, Clam Pass was a small part of a large system of waterways extending from Lee County to Doctors Pass. A limited amount of small boating activities took place within this area. The construction of Vanderbilt Beach Road in the early 1950's cut off any navigation from the north from what is presently called Vanderbilt Lagoon. Tidal connection with Vanderbilt Lagoon was eventually severed as well. Later, the construction of Seagate Drive limited the amount of tidal flow from the south,the waterway presently called Venetian Bay which connects to Doctors Pass Prior to the surrounding development, the natural stormwater (rain run-off) flow in this area was by sheet flow in a southwesterly direction towards the Inlet. The stormwater flow pattern has since been modified in direction, volume, and timing by the use of retention/detention basins, primarily in the Pelican Bay development area. The Clam Pass opening has moved over its lifetime up and down the shoreline, influenced by major storm events and by man's alteration of the tidal prism and drainage basin that feeds the Pass. A detailed discussion of the Pass is provided in the Coastal Processes Element of this Plan. CLAM PASS NRPA MANAGEMENT PLAN(DRAFT) Pelican Bay Services Division September 3, 2013 3.0 Historical Overview Original land use, development history, die-off and restoration work. To properly understand and successfully implement proposed management objectives, actions and events which have lead to the current situation in Clam Bay should be described. This chapter starts off with a time-line to most clearly portray the system in its historical context. It is intended as background information and as a factual recount based on personal experiences and comments, press reports, published and unpublished reports. The chapter finishes with an overview of the mangrove die-off including causes, and the work that was undertaken as part of the 1998 Clam Bay Restoration and Management Plan to restore the system. Time Line 1920 A dirt road is built by Forest Walker running from the north-east to south portion of Pelican Bay, a forerunner of US 41. 1950 With 6,000 residents of Naples, Clam Bay is part of a connected system of barrier islands, mangrove passes and waterways. The orientation of the beaches and passes would have changed seasonally and with storms Late 1950's Vanderbilt Road is constructed severing connection with the Wiggins Pass system to the north. 1958 Seagate Drive is constructed as the Parkshore community is developed. Flow is blocked into Venetian Bay to the south. r ,: ,DSN-1 -9" Vanderbilt Lagoon i . . . a:.: 'AEC- ..; 4'1`' `� rA- ' - ... =:.• Outer Clam Bay A;t ,,/ is s Upper Clam Bay t s)-i, ` 1 Z 'ti' a �� 4 F •F-. , .14,T,,, j :a.. +� d r j �1 Venetian YBay }-v"- ' r { G* a Circa 1960 Aerial Photograph Circa 1958 Aerial Photograph CLAM PASS NRPA MANAGEMENT PLAN(DRAFT) - Pelican Bay Services Division September 3, 2013 1972 Tri-County Engineering produces reports: • An Ecological Study of the Clam Pass Complex is published by Humm&Rehm • Hydrographic Investigation of the Clam Bay System Coral Ridge-Collier Properties, Inc.

A DNR interdepartmental memo highlights cause of the stress as "the lack of adequate water circulation resulting from the closure of Clam Pass". First emergency dredging permit received from DNR to re-open clogged Clam Pass, following memo by David Crewz to the DNR highlighting problems and danger if the pass was not re- opened. 1990 Pelican Bay Improvement District comes under Collier County as the Pelican Bay Services Division. 1992 The area of dead mangroves is reported at 7 acres. 1994 20 acres of mangroves are reported dead. 1994 Clam Bay is approved by the Board of County Commissioners as Collier County's first Natural Resource Protection Area(NRPA). 1995 Emergency dredging permit issued allowing opening of the pass, but no work farther back than 600 feet. CLAM PASS NRPA MANAGEMENT PLAN(DRAFT) Pelican Bay Services Division September 3, 2013 1996 Permits to open Clam Pass received from DEP and USACE and work completed in April.

In March dredge work is completed and the pass is open. Development of a new Management Plan is initiated through stakeholder input and multiple public meetings. 1995 Die-off and Related Causes The majority of the original die-off occurred within the northernmost black mangrove areas of the system. Three defined processes of the black mangrove forest are applicable to the Clam Bay ecosystem. These three processes are briefly reviewed here are: Salt balance: Salt is available to the black mangrove forest from a variety of sources,but normal tidal exchange is the most important. Black mangroves can tolerate slightly higher sediment salinity than the other two mangrove species but can be affected adversely by an excess accumulation of salt. In a natural setting,toxic accumulation of salt is usually prevented by dilution and leaching due to rainfall and washout on outgoing tides. Accordingly, the transport of dissolved and diluted salt back to the Gulf is critical to the health of the black mangrove. Organic matter budget: Like the salt balance,the organic matter budget is intimately related to the flushing component of the tidal cycle. It is generally recognized that even in the best of circumstances only 60-86% of the decomposing matter generated by a mangrove forest is consumed on site. The balance has to be exported. This export is in the form of highly fragmented or dissolved organic matter fractions and as such is also dependent upon tidal flushing. Water budget: Water enters the Clam Bay system through rainfall, freshwater run-off and through the influx of seawater. It leaves via evaporation from water surfaces, transpiration from leaves and tidal out-flow to the Gulf. Since evapotranspiration rates within mangrove forests are relatively low it follows that the forest must freely drain or else water logging occurs that quickly leads to stress and mortality. Rainfall in South Florida contributes about 53 plus inches of water per year and most of that occurs in the wet season. Additional freshwater inputs to this system occur from groundwater flow and from irrigation in the developed portions of Pelican Bay. The irrigation amounts to about 26 to 28 inches (on average) of rainfall every year but can vary widely due to weather conditions. In a perfect world this irrigation component would be entirely taken up by the soil and plants but in these non-perfect conditions, it is expected that some run-off is also generated due to the irrigation. When this amount is added to normal rainfall, the export capacity of the system to the Gulf becomes critical, especially when considered in the context of the need to transport the organic matter and salt described above. • CLAM PASS NRPA MANAGEMENT PLAN(DRAFT) Pelican Bay Services Division September 3, 2013 The combination of these mangrove species and other intertidal vegetation makes mangrove forests extremely productive natural resources,but their productivity depends on the right combination of tidal "flushing" (movement of water and suspended material in and out of the estuarine wetland) and freshwater run-off to maintain their ability to function. The freshwater input dilutes the high salinity of marine waters, thereby reducing the effort needed by the mangrove to exclude or excrete salt. This allows more of the trees' energy to be directed to normal growth and maintenance. Tidal flushing also allows nutrients to be distributed within the forest and provides for the transportation of dead leaves, twigs, etc. As these materials decay,they become food for marine life. It is this mangrove detritus which is consumed by the many organisms at the base of the food chain and which in turn create the next level of the food chain necessary to support the fish populations that characterize the mangrove community. It is the combined interaction of fresh and salt water through tidal flushing that is critical to the ability of the mangrove forest to sustain itself. It follows therefore, that anything that materially disrupts the maintenance of the flushing component threatens the long term viability of the mangrove forest itself According to detailed field surveys performed in the early 1970's (Tropical BioIndustries Company and Gee and Jenson 1978)tree densities ranged from 726 to 7,580 per acre and maximum canopy height was 39 feet. Within the black mangrove dominated basin forests, 16% of the trees or 8.8 acres of dead black mangroves were reported in the 1978 document. Dead and stressed mangroves were again reported for Clam Bay in 1989 when David W. Crewz, a biologist with the Florida Marine Research Institute,was asked to inspect Clam Pass Park by Mary Ellen Hawkins,then a Collier County representative to the legislature (letter to Don Duden dated April 3, 1989). Mr. Crewz concluded that the"dead and stressed mangroves were caused by lack of adequate water circulation resulting from the closure of Clam Pass.... allowing toxin and salt buildup." Westinghouse Consultants, Inc., employees in February 1992 noted additional mangrove die-offs, north of Clam Pass Park on the west side of Upper Clam Bay. This area was inspected by Dr. Eric Heald, a consultant to WCI, and reported to WCI in April 1992, as probably due to hypersalinity, although 1991 was an above average rainfall year. The same conclusion was reached by Robin Lewis of Lewis Environmental Services, Inc., after an inspection in May 1994. At this time the die-off area was approximately 6 acres. A widespread mortality of mangroves in Florida Bay was also reported in the summer of 1991 (Yarbro et al. 1994) and it was attributed, in part,to natural drought conditions and unusual tidal inundation patterns. After above average rainfall in the summer of 1995, The Conservancy, Inc.'s staff and residents in Pelican Bay reported additional mangrove deaths which continued through 1995 and 1996. The total area of the die-off through July 1999 was around 50 acres. The death of trees occurred around hyper saline ponds and is consistent with conditions caused by periods of excessive inundation of freshwater followed by periods of continuous dry down, CLAM PASS NRPA MANAGEMENT PLAN(DRAFT) Pelican Bay Services Division September 3, 2013 particularly where the mechanism for flushing is impaired. (Lugo 1976). During the period immediately preceding the observed die off, and during the periods following, Clam Bay received record amounts of rainfall. This rainfall, when coupled with an admittedly impaired circulation system and intermittent pass closure, resulted in water levels that were high enough for a long enough period of time to adversely impact the mangroves. It should be noted, however,that the death of trees around hyper saline ponds is a process that is now occurring for a variety of reasons elsewhere in Florida and the Caribbean and is not necessarily evidence that the forest is in a state of irretrievable decline. The presence of new seedlings confirms that these conditions may well be able to return. (Lugo 1976;). Presently the die-off areas appear to be recovering as a result of the restoration work done to date. The remedial efforts described later in this Plan, in particular the dredging of Clam Pass and the opening of several of the impacted tidal creeks,have had the desired effect of improving the circulation of tidal waters within the system. (Humiston, pers. comm. 2007). Restored Characteristics of Clam Bay In assessing a variety of alternatives to the restoration of Clam Bay,the original need was not so much to restore the system to a mangrove forest(although that remained the primary goal) as it was to stabilize and restore the system as a thriving natural resource. It was recognized that with changes to naturally induced flushing rates and hydrological regimes the mangroves would likely adjust by altering zonation patterns, species compositions, rates of growth and mortality, etc. (CBRMP 1998). Clam Pass The single most important thing that has been done to restore the health of the Clam Bay system is to improve the total tidal flushing capacity of the system. (Humiston& Moore 2003; Lewis 2007; Turrell 2007). As has been discussed earlier, the tides in the upper reaches of Clam Bay were weak and variable. Runoff from rainfall further reduced the interior tidal range and during Tackney's field study,total rainfall of approximately 4 inches in three days was sufficient to flood Upper Clam Bay to such an extent that tidal fluctuation was completely eliminated. During Hurricane Charlie, storm surge and rainfall far exceeded this 4 inch level and yet Upper Clam Bay was experiencing tidal fluctuations the following day. The restoration efforts of dredging the pass, dredging the interior channels, and construction of the network of flushing cuts throughout the original die-off area proved very effective in maintaining the tidal exchange and drainage capability of the system. In Outer Clam Bay, where the channel leading to Clam Pass is relatively short, the tidal range was only 50% of its potential value. This diminished exchange capacity was a direct result of the constricted nature of the inlet and its adjacent interior channels. CLAM PASS NRPA MANAGEMENT PLAN(DRAFT) Pelican Bay Services Division September 3, 2013 During flood tides, sand is carried into the pass by tidal currents and settles out of the water column where the current drops below the magnitude necessary to maintain the sediment in suspension. At Clam Pass this has resulted in the gradual accumulation of sediment in the channels interior to the inlet. This sedimentation process reduces the hydraulic efficiency of the channels and results in diminished tidal ranges for the interior bays. In 1998, when the restoration activities commenced, the channels immediately interior to the pass were so constricted that even when the pass was excavated, the interior tides remained muted. Efforts to maintain the pass in an open condition were dramatically improved by enlarging the dredge area to include not only Clam Pass,but also the critical areas of the adjacent interior channels. This action not only augmented the volume of tidal flow through Clam Pass, but also reduced the likelihood of inlet closure during adverse weather conditions. Currently, Outer Clam Bay's tidal range has been improved by 4 to 6 inches as a result of the dredging activities and the increased self-maintenance capability of the inlet. The single most critical causative factor of the Upper Clam Bay mangrove die off and lack of natural regeneration of mangroves was the relative absence of adequate tidal flushing, or tidal pumping, typically measured in terms of tidal amplitude and its frequency of occurrence (CBRMP 1998, Roessler pers. comm. 2004). Tidal pumping refers to the hydraulic change in water pressure in mangrove sediment that is controlled largely by tidal activity. When rising tides force a rise in the water table in the sediment beneath mangroves, gasses(e.g., carbon dioxide, hydrogen sulfide, methane, ammonia) and various fluid wastes (including refractory and labile dissolved organic matter) are expelled from the sediment. Since some of these compounds are toxic,particularly hydrogen sulfide, their frequent(daily to twice daily) removal is critical to the health of the mangroves. Conversely, on falling ties and a drop in the sediment water table, gases (e.g., oxygen) and nutrients present in the over-lying water are drawn into sediment. The frequent renewal of sediment oxygen is particularly important because it is required in normal root respiration which, if stopped, causes mortality. Thus in the absence of tidal pumping, metabolic wastes accumulate in the sediment and it eventually turns toxic and anoxic, meaning no oxygen. It is important to note that this critical process has nothing to do with the salinity, or absence thereof, or with the presence of absence of surface and subsurface water. Because the tidal amplitude was wholly inadequate mainly due to the restricted tidal circulation and tidal pumping within the Clam Bay system, and between the Clam Bay system and the Gulf of Mexico, the correction provided by the restoration activities has been critical to the creation and management of conditions required to foster mangrove growth in addition to maintaining water quality within Clam Bay. Interior Tidal Creeks It is also important to recognize the interrelationship between the maintenance of Clam Pass and the maintenance of the interior connecting tidal creeks. The tides in the upper reaches of Clam Bay were weak and variable. In the absence of rainfall, the tidal ranges of the Upper and Inner Clam Bay's were on the order of 15%to 19% of the Gulf tidal range. Run-off from rainfall quickly flooded the upper bays and further reduced the interior tidal range. The reduced tidal CLAM PASS NRPA MANAGEMENT PLAN(DRAFT) Pelican Bay Services Division September 3, 2013 range in the interior bays were due to the restrictive condition of the interior connecting tidal creeks. (Tackney 1996; CBRMP 1998). These restrictions not only super-elevated the average water surface elevation within the bays but also retarded drainage. The problem was exacerbated by the addition of pulsed water from the stormwater management system, which by design stores water in its detention/retention areas and then allows it to discharge into the bays. The constricted condition of the interior tidal creeks coupled with the additional water being continuously discharged into the bay elevated the water surface elevation in the upper bays and contributed to extending the periods of flooding beyond tolerance levels that mangroves can accommodate,particularly the black mangrove. (Turrell 1995; Tackney 1996; Lewis 2007). The second restorative action of the plan required that three sections of interior tidal creek be dredged open and in some cases enlarged in order to augment the transfer of water. Removing the constrictions present in these waterways allowed the increased inflow of water as well as enhancing the outflow of water. These adjustments enhanced the flood tide ingress and allowed for increased volume to exit on the ebb tide. The results of this work showed an almost doubling of the tidal amplitude in the upper reaches of the system. While the amplitude is still far below the levels seen in the Gulf, it is still much improved from the pre-restoration levels. Interior Flushing Channels The third restorative action of the original plan was the creation of a network of flushing cuts within the mangrove forest and die-off areas. These cuts were dug by hand throughout the system the purpose of which was to connect depressional zones and areas subject to ponding to the main waterways of the system. This allowed for tidal water to flow into and out of the forest areas much easier and further enhanced the tidal exchange that could occur. Biological monitoring work over the past ten years has conclusively shown that the improved drainage, which has been achieved through excavation of these small flushing cuts within the forest basin, has greatly alleviated ponding and contributed to the observed improvements in the Clam Bay mangrove community. CLAM PASS NRPA MANAGEMENT PLAN(DRAFT) • Pelican Bay Services Division September 3, 2013 4.0 Resource Description and Assessment SOILS Based on the National Resource Conservation Service (NRCS) "Soil Survey of Collier County Area, Florida" (NRCS, 1998) there are 8 different soil types (soil map units) present on the project lands. Two of the units are associated with the NRPA while the remaining units are associated with the upland developments. The following sub-sections provide a brief description of each soil map unit identified within the Clam Bay and Pelican Bay areas. Information is provided about the soil's landscape position(i.e. its typical location in the landscape on a county- wide basis), the soil's profile (i.e. textural composition and thickness or depth range of the layers or horizons commonly present in the soil), and the soil's drainage and hydrologic characteristics. In addition, the hydrologic soil group is also identified for each soil. There are 4 groups that are used to estimate runoff from precipitation. Soils are grouped according to the rate of infiltration of water when the soils are thoroughly wet and are subject to precipitation from long-duration storms. The four groups range from A (soils with a high infiltration rate, low runoff potential, and a high rate of water transmission) to D (soils having a slow infiltration rate and very slow rate of water transmission). It is important to understand that where the soil survey shows mapping units named for soil series, they represent the dominant undisturbed soils in that landscape that existed predevelopment. They do not recognize or appropriately interpret the drastically disturbed nature of urban landscapes created after the Soil Survey was completed. The soils occurring within the development areas are as follows: Immokalee fine sand(Map Unit#7) Landscape position—Pine Flatwoods. This is a nearly level, poorly drained soil. Individual areas are elongated and irregular in shape, and range from 10 to 500 acres. The slope is 0 to 2 percent. Typically, the surface layer is black fine sand about 6 inches. The subsurface layer is light gray fine sand to a depth of about 35 inches. The subsoil is fine sand to a depth of about 58 inches; the upper part is black, the middle part is dark reddish brown, and the lower part is dark brown. The substratum is pale brown fine sand to depth of about 80 inches. The permeability of this soil is moderate. The available water capacity is low. In most years, under natural conditions,the seasonal high water table is between 6 to 18 inches of the surface for 1 to 6 months. In other months, the water table is below 18 inches and recedes to depth of more than 40 inches during extended dry periods. Rarely is it above the surface. Hydrologic group is B/D. Natural vegetation consists of South Florida slash pine, saw palmetto, wax myrtle, chalky bluestem, creeping bluestem and pineland threeawn. CLAM PASS NRPA MANAGEMENT PLAN(DRAFT) - Pelican Bay Services Division September 3, 2013 Urban land(Map Unit#32) Landscape position—Urban Areas Urban land consists of areas that are 75 percent or more covered with streets, buildings, parking lots, shopping-centers, highways, industrial areas, airports and other urban structures. Small areas of undisturbed soils are mostly lawns, vacant lots, playgrounds and green areas. The original soils in some areas have been altered by filling, grading and shaping. Urban land is nearly level except for some parking areas that are sloped to drain off water. Individual areas are usually rectangular in shape and range from 10 to 1200 acres. The slope is 0 to 2 percent. The depth of the water table varies with the amount of fill material and the extent of artificial drainage within any mapped area. Hydrologic group is not applicable. Urban Land-Immokalee-Oldsmar limestone substratum Complex (Map Unit#34) Landscape position—Urban Areas These nearly level poorly drained soils are on urban areas of the county. Individual areas are blocky to irregular in shape and range from 20 to 500 acres. The slope is 0 to 2 percent. Typically, urban land consists of commercial buildings, houses, parking lots, streets, sidewalks, recreational areas, shopping centers and other urban structures where the soil cannot be observed. In 90 percent of the area mapped in this unit; urban land makes up about 45 percent, Immokalee soils makes up about 35 percent and Oldsmar soil makes up about 20 percent of the map unit. The soils occur as areas so intricately mixed or so small that mapping them separately is not practical. The Immokalee and Oldsmar soils may or may not have been filled or reworked to accommodate Urban land uses. The permeability of the Immokalee is moderate and the available water capacity is low. The permeability of the Oldsmar soil is moderately slow and the available water capacity is low. In most years, under natural conditions, the seasonal high water table is between 6 to 18 inches of the surface for 1 to 6 months. In other months, the water table is below 18 inches and recedes to a depth of more than 40 inches during extended dry periods. Most areas have had drainage systems installed to help control the seasonally high water table and runoff. Hydrologic group is B/D. Urban Land Aquents Complex, organic substratum (Map Unit#35) Landscape position—Urban Areas. This unit consists of soil materials that have been dug from different areas in the county and have been spread over the muck soils for coastal urban development. Individual areas are blocky to irregular in shape and range from 20 to 300 acres in size. The slope is 0 to 2 percent. Typically, Urban land consists of commercial buildings, houses, parking lots, streets, sidewalks, recreational areas, shopping centers and other urban structures where the soil cannot be observed. The depth of this fill material varies from 30 to more than 80 inches. Muck of various thickness underlies the fill material, with mineral material under the muck. The depth to the water table varies with the amount of fill material and the extent of artificial drainage within any mapped area. Hydrologic group is not applicable. Udorthents shaped(Map Unit#36) Landscape position—Golf courses and athletic fields. These nearly level to undulating, somewhat poorly to moderately well drained soils are on golf courses and adjacent areas where soil material has been mechanically altered and shaped.

This map unit is comprised of many altered soils with widely differing chemical and physical characteristics. Some areas maybe comprised entirely of fine sands to a depth of 80 inches. The depth to the water table varies with the amount of fill material and the extent of irrigation and artificial drainage within any mapped area. Hydrologic group is D. Satellite fine sand(Map Unit#39) Landscape position—Coastal ridges. This nearly level, somewhat poorly drained soil is on low-lying coastal ridges. Individual areas are elongated and irregular in shape and range from 10 to 400 acres. The slope is 0 to 2 percent. Typically, the surface layer is gray sand about 3 inches thick. The substratum is light gray to white fine sand to a depth of about 80 inches. Permeability is very rapid. The available water capacity is very low. In most years, under natural conditions, the seasonal high water table is at a depth of between 18 to 10 inches for 1 to 4 months. In other months, the water table is below 40 inches. Rarely is it above the surface. Hydrologic group is C. Natural vegetation consists of Florida rosemary, sand live oak, south Florida slash pine, sawpalmetto,prickly pear, pineland threeawn and creeping bluestem. The soils occurring within the NRPA are as follows: Durbin and Wulfert mucks, frequently flooded(Map Unit#40) Landscape position—Mangrove swamps. These level, very poorly drained soils are in tidal mangrove swamps. Individual areas are elongated and irregular in shape and range from 50 to 1000 acres. The slope is 0 to 1 percent. Typically,the Durbin soil has a surface soil of dark reddish brown to black muck about 63 inches thick. The substratum is dark gray fine sand to a depth of about 80 inches. Typically, the Wulfert soil has a surface soil of dark reddish brown to black muck about 40 inches thick. The substratum is dark gray fine sand to a depth of 80 inches. The permeability of the Durbin soil is rapid and the available water capacity is high. The permeability of the Wulfert soil is rapid and the available water capacity is moderate. The water table fluctuates with the tide and is within 12 inches of the surface most of the year. The soil is subject to tidal flooding. Hydrologic group is D. Natural vegetation consists of red, white and black mangroves. Canaveral-Beaches Complex (Map Unit#42) Landscape position—Beaches and low coastal ridges This map unit consists of the nearly level, moderately well drained Canaveral soil on low ridges and of beaches.

Natural vegetation consists of Australian pines, sea oats, sea grape, cabbage palm, Brazilian pepper and salt grasses. Insert Soils Map when Available CLIMATE Clam Bay's climate falls within tropical classification, more precisely the tropical wet and dry or savanna type, Aw under the Koppen system. As a consequence,there are essentially two seasons are experienced. The wet season occurs in the summer and the dry season occurs in the winter. Typical rainfall and temperature data is provided in Tables 4.1 and 4.2. In the summer the center of the trade winds shift north and moisture-laden breezes blow from the east or south-east. In winter, the trade winds shift southward and the winds are less constant. Weather, is then more influenced by fronts advancing from the northwest. This brings cooler conditions, although temperatures never reach freezing, due to the fact that they are being moderated by the surrounding waters. Cold fronts are typically preceded by winds from the southwest, which clock to the west then northwest as the front passes, with strong winds of 20-25 knots and cooler air. In general terms, winds are predominantly southeast during the summer and northeast during the winter. Historical meteorology for Clam Bay is based on data collected for 30 years (from 1981 to 2010) from the Naples Municipal Airport by the Florida Climate Center (NOAA & FSU). The following charts present meteorological statistics for temperature and precipitation.

Wind speeds, not including storm events are, on average, below 10 knots. During the winter months when fronts move through, for a day or two at a time, winds out of the northwest to northeast may increase to about 25 knots. Sea breeze As the land surface around Naples and Clam Bay heats it in turn heats the air above it. The warm air is less dense and tends to rise creating a lower air pressure over the land than the water. CLAM PASS NRPA MANAGEMENT PLAN(DRAFT) Pelican Bay Services Division September 3, 2013 The cooler air over the water then flows inland creating a sea breeze. In the evening the reverse occurs and the cooler air over the land will flow back toward the water creating a land breeze. The incoming sea breeze acts as a lifting mechanism, resulting in the warmer air rising up to higher altitudes. This creates cumulus clouds that begin to build which leads to the development of afternoon showers and thunderstorms in the area. Storms Naples and Clam Bay specifically are within the Atlantic Tropical Cyclone basin. This basin includes much of the North Atlantic, Caribbean Sea, and the Gulf of Mexico. On average, six (6) to eight (8) tropical storms form within this basin each year. The hurricane season lasts from June 1st to December 1St. The formation of these storms and possible intensification into mature — — -- hurricanes takes place over warm tropical and subtropical { Safflr-Simpson Hurricane Scale Category Wind speed Storm surge waters.

Three species are common in Florida as far north as Cedar Key and St. Augustine, where cold winter temperatures limit their range. All have special biological adaptations to cope with salt and unstable, mucky, low oxygen soils that result in a tidal, hence continually waterlogged environment. The dominance of mangroves in tidal areas is a function of these adaptations and hence their ability to out-compete other wetland plants. Red mangroves (Rhizophora mangle) are recognized by their tangle of reddish looking prop roots, long cigar shaped seedlings (the propagules which can be seen in the summer months) and their large, pointed evergreen leaves. They are typically the most seaward of the three species with the prop roots and vertical drop roots providing support, small pores on the trunks called lenticels allow oxygen exchange via air as the waterlogged soils become rapidly oxygen depleted. Salt is excluded from the plants cells through a process called ultra-filtration in the roots. The characteristic propagules germinate on the parent tree and drop and float for up to a year, finally becoming heavier at one end so that when encountering a suitable substrate they are ready to root upright. Good tidal flushing is essential for healthy development of red mangroves, to prevent the build up of toxic metabolic waste products in the mangrove soils. The mass of prop and drop roots forms extensive surface area under water for attachment of sessile, filter feeding marine species (such as sponges, tunicates and mollusks) as well as hiding places for juvenile fish. Birds, butterflies, insects and mammals find home and food within the canopy. Fall and breakdown of Red mangrove leaves is the start of productive estuarine food webs. Black mangroves (Avicennia germinans) are typically found slightly further inland and key identification features include the snorkel like pneumaptophores which radiate upwards out of the soil from the base of the trunk, a grey-black rough bark and slightly pointed, oval leaves which are silvery with salt deposits on the undersides. The pneumatophores play an important role in oxygen exchange and unlike the Red mangroves, which keep salt, out of body cells, the Black mangrove excretes salt onto the backside of the leaves. They are also reliant on adequate tidal exchange but lack the supporting prop roots that typify the Red mangrove. Small white flowers and small lima bean shaped propagules are apparent during the summer months and, on falling from the parent tree, float for a short period and establish in the mucky soil. CLAM PASS NRPA MANAGEMENT PLAN(DRAFT) Pelican Bay Services Division September 3, 2013 invertebrates that scavenge detritus or, in the case of many bivalve mollusks, extend siphons at high tide and filter vast quantities of water. Birds such as a variety of herons, ibis, egrets and spoonbills pick through the sediment for the invertebrate food sources. Sandy Beach In addition to the 35-acre Clam Pass Beach Park, south of the pass, sandy beach also extends north all the way to Wiggins Pass. Shorebirds feed on marine invertebrates such as coquina clams and mole crabs at the water's edge and beaches are crucially important habitat for nesting sea turtles. Coastal plants colonizing the dunes are key players in trapping windblown sand and preventing coastal erosion as the first defense against heavy winds and surge of tropical storms. Species common on the beaches of the Clam Bay system include; Sea oats (Uniola paniculata), Seagrape (Coccoloba uvifera), Cabbage palm (Sabal palmetto), Buttonwood (Conocarpus erectus) and Railroad vine (Ipomoea pes-caprae). Brackish Marsh At the interface between forested mangrove areas and the water management berm are depressional areas that have become colonized by aquatic freshwater plants such as cattails (Typha latifolia), Carolina willow (Salix caroliniana), Bulrush (Scirpus californicus), Needlerush (Juncus romerianus) and Leather fern (Acrostichum danaeifolium). Wildlife such as otters (Lutra canadiensis), alligators (Alligator mississippiensis), various turtles, and wading birds can be commonly observed. These areas require regular maintenance to prevent the spread of nuisance and exotic plant species and ensure optimal functioning of the water management system. Add FLUCFCS Exhibit when available Tidal Passes The Clam Bay system was originally part of a larger tidal system connected to the Gulf of Mexico by three tidal inlets; Wiggins Pass, Clam Pass and Doctors Pass. During the 1950's and 60's this system was isolated from adjacent bays by the construction of Seagate Drive to the south and the construction of Vanderbilt Beach Road to the north. The practical effect was to leave Clam Pass as Clam Bay's only connection to the Gulf. The exchange of seawater between Clam Bay and the Gulf is critical to the ability of the mangrove forest to export organic matter, as well as excess salt and freshwater. It also supplies oxygen rich water and nutrients from the Gulf. The greater the tidal amplitude (or tidal prism) the greater the benefit to the mangroves — more needed resources are delivered and more wastes are removed. Conversely, in the absence of surface water circulation or tidal activity, mangroves slowly die due to deleterious changes in the sediment: 1) in the absence of oxygenated water, the sediments become anaerobic or anoxic, and 2) metabolic wastes and hydrogen sulfide accumulate in the anoxic sediment (CBRMP, 1998). • CLAM PASS NRPA MANAGEMENT PLAN(DRAFT) Pelican Bay Services Division September 3, 2013 Tides in the Gulf of Mexico are mixed, with the norm being two high tides and two low tides experienced per day and normal amplitude (range) of approximately 2 feet. The highest tides (springs) are experienced twice per lunar month at full and new moons when the gravitational pull on the earth's surface waters is greatest. Neap tides also occur twice per lunar month when the planetary (gravitational) influences of earth,moon and sun are perpendicular. Add Tidal Exhibit from Clam Bay Monitoring Report It can be seen that the health of mangrove forests is directly related to the efficiency of the tidal passes. These are dynamic creeks whose location vary annually and, as illustrated by Clam Pass, can periodically close such as has happened at least four times in the last 25 years (Turrell 1995; Tackney 1996). Tidal creeks are passageways for fish and marine invertebrates between the open waters of the Gulf and the protected embayments of Clam Bay. Manatees and turtles may also use the passes. Scouring action of the fast flowing tide generally prevents colonization by seagrasses and other benthic plants and the substrate is typically sand and shell with the finer sediments carried in suspension and deposited just outside the mouth of the pass (the ebb shoal delta) or to the interior of the system on the incoming(flood)tide.

In about 10-15 feet of water a variety of sponges, stony corals, gorgonians, fish and associated invertebrates can be found within a system of rocks and ledges. Outcroppings of similar habitat type occur along the length of Collier County and are a little known resource of regional significance. PLANT SPECIES -List to be added based on FLUCFCS Mapping LISTED SPECIES Smalltooth Sawfish (Pristis pectinata) A juvenile smalltooth sawfish was observed in 2008 in the connector creek between Inner and Outer Clam Bays. Smalltooth sawfish are found in the tropical and subtropical Atlantic Ocean. In the western Atlantic they have historically ranged from New York to Brazil, including the Gulf of Mexico and Caribbean Sea. Habitat destruction and overfishing have succeeded in eradicating the smalltooth sawfish from the majority of its former range. Consequently, it survives in small pockets throughout its current range. The last remaining population in U.S. waters is off south Florida, a small remnant of a population that once ranged from New York to Texas. This sawfish primarily occurs in estuarine and coastal habitats such as bays, lagoons, and rivers. It does at times occur in deeper waters, however, and may make crossings to offshore islands. It can tolerate freshwater. This fish is easily recognized by its flattened body and wing-like pectoral fins. The mouth is located ventrally, the eyes are positioned dorsally. The "saw" is approximately 25% of the body's total length. It is widest at the base, with teeth more broad than long, and spaced apart. The tips of the teeth are sharp, becoming blunt over time. Dorsally, it is brownish or bluish gray body with a white underside. The maximum length recorded is 24.7 feet (7.6 m); however, a length of 18 feet (5.5 m) is considered average. The average lifespan for the smalltooth sawfish is unknown. On April 1, 2003 the U.S. National Marine Fisheries Service placed the smalltooth sawfish on the Endangered Species List, making it the first marine fish species to receive protection under the Endangered Species Act. Florida has also designated critical habitat areas to further protect its habitat. Mangrove Rivulus (Rivulus marmoratus) This small fish has not been identified within the Clam Bay system in previous surveys or field work but the mangrove habitat is appropriate and they could be present in the upper reaches of the mangrove forest. The mangrove rivulus is primarily a saltwater or brackish water species, CLAM PASS NRPA MANAGEMENT PLAN(DRAFT) Pelican Bay Services Division September 3, 2013 with limited occurrence in freshwater. Within the Everglades and along Florida's west coast, this fish occurs in stagnant, seasonal ponds and sloughs as well as in mosquito ditches within mangrove habitats.The mangrove rivulus is able to survive in moist detritus without water for up to 60 days during periods of drought, anaerobic, or high sulfide conditions. This fish can reach a maximum size of 2 inches (5 cm) in length, however it is more commonly observed at lengths between 0.4-1.5 inches (1.0-3.8 cm). The head and body are maroon to dark brown or tan, with small dark spots and speckling on the body, particularly the sides. The dorsal surface is always darker than the creamy ventral surface. The color of the body is reflective of the habitat, with light coloration in areas of light colored sediments and darker coloration in environments with dark leaf litter substrates. A large dark spot surrounded by a band of yellow is located at the upper base of the caudal fin in hermaphroditic individuals. Males lack this dark spot and have a red-orange cast to their flanks and fins. The mangrove rivulus was once listed as a threatened species in the Gulf of Mexico. However, recently additional surveys have revealed the existence of numerous populations. In Florida it has been downlisted to a species of special concern. In 1999, it was submitted by the National Marine Fisheries Service as a candidate for protection under the Endangered Species Act. As of yet, it has not been officially listed as endangered or threatened. The main threat to the survival of the mangrove rivulus is habitat degradation and destruction as well as exposure to pollutants. Disturbances that alter salinity and temperature as well as vegetation cover may also reduce naturally occurring populations. Loggerhead Sea Turtle (Caretta caretta) Loggerhead sea turtles have been documented nesting on beaches within the Clam Bay NRPA. Loggerheads are circumglobal, occurring throughout the temperate and tropical regions of the Atlantic, Pacific, and Indian Oceans. They are the most abundant species of sea turtle found in U.S. coastal waters. In the Atlantic, the loggerhead turtle's range extends from Newfoundland to as far south as Argentina. During the summer, nesting occurs primarily in the subtropics. Although the major nesting concentrations in the U.S. are found from North Carolina through southwest Florida, minimal nesting occurs outside of this range westward to Texas and northward to Virginia. Adult loggerheads are known to make extensive migrations between foraging areas and nesting beaches. During non-nesting years, adult females from U.S. beaches are distributed in waters off the eastern U.S. and throughout the Gulf of Mexico, Bahamas, Greater Antilles, and Yucatan. Loggerheads were named for their relatively large heads, which support powerful jaws and enable them to feed on hard-shelled prey, such as whelks and conch. The top shell (carapace) is slightly heart-shaped and reddish-brown in adults and sub-adults, while the bottom shell (plastron) is generally a pale yellowish color. The neck and flippers are usually dull brown to reddish brown on top and medium to pale yellow on the sides and bottom. CLAM PASS NRPA MANAGEMENT PLAN(DRAFT) Pelican Bay Services Division September 3, 2013 In the southeastern U.S., mating occurs in late March to early June and females lay eggs between late April and early September. Females lay three to five nests, and sometimes more, during a single nesting season. The eggs incubate approximately two months before hatching sometime between late June and mid-November. Loggerheads occupy three different ecosystems during their lives: beaches (terrestrial zone), water (oceanic zone), and nearshore coastal areas ("neritic" zone). Because of this, NOAA Fisheries and the U.S. Fish and Wildlife Service (USFWS) have joint jurisdiction for marine turtles, with NOAA having the lead in the marine environment and USFWS having the lead on the nesting beaches. The loggerhead turtle was first listed under the Endangered Species Act as threatened throughout its range on July 28, 1978. In September 2011, NMFS and U.S. Fish and Wildlife Service listed 9 Distinct Population Segments of loggerhead sea turtles under the ESA. The population in our Northeast Atlantic Ocean Segment is listed as endangered. The agencies are currently proposing Critical Habitat designations on several areas which contain a combination of nearshore reproductive habitat, winter area, breeding areas, and migratory corridors. The Clam Pass NRPA is contained within the LOGG-N-27 segment of this proposed critical habitat area. Gopher Tortoise (Gopherus polyphemus) Gopher tortoises and their burrows are found along the coastal strand portions of the Clam Pass NRPA. The range of the tortoise includes southern portions or Alabama, South Carolina, Louisiana, Mississippi, and Georgia as well as most of Florida. Gopher tortoises are one of the few species of tortoise that dig burrows. These burrows can be up to ten feet deep and 40 feet long, and are as wide as the length of the tortoise that made it. In addition to providing the tortoise a home, it has been documented that as many as 350 other species also use the burrows including the indigo snake, Florida mouse, gopher frog and burrowing owl. Gopher tortoises can live 40 to 60 years in the wild and average 9 to 11 inches in length. These tortoises are superb earth-movers, living in long burrows from 5 to 45 feet long and up to 10 feet deep that offer refuge from cold, heat, drought, forest fires and predators. The burrows maintain a fairly constant temperature and humidity throughout the year and protect the gopher tortoise and other species from temperature extremes, drying out, and predators. The mating season generally runs from April through June and gestation for the eggs is between 80 and 100 days. The shell or "carapace" of the gopher tortoise is mostly brownish gray and the underside of the shell, or "plastron," is yellowish tan. Their front legs are shovel-like which helps them when digging their burrows. The gopher tortoise has been regulated in Florida since 1972 and has been fully protected since 1988. Despite the afforded protection, gopher tortoise populations throughout the state have declined. As a response to the continuing decline of the species, a new management plan was drafted and approved in September 2007 as a precursor to reclassifying the gopher tortoise from CLAM PASS NRPA MANAGEMENT PLAN(DRAFT) - Pelican Bay Services Division September 3, 2013 a "species of special concern" to a "threatened species." The threatened status was approved and went into effect on November 8,2007. West Indian Manatee Manatees have been sighted on numerous occasions within the Clam Pass NRPA boundaries. Manatees can be found in shallow, slow-moving rivers, estuaries, saltwater bays, canals, and coastal areas—particularly where seagrass beds or freshwater vegetation flourish. Manatees are a migratory species. Within the United States, they are concentrated in Florida in the winter. In summer months, they can be found as far west as Texas and as far north as Massachusetts, but summer sightings in Alabama, Georgia and South Carolina are more common. Manatees are large, gray aquatic mammals with bodies that taper to a flat, paddle-shaped tail. They have two forelimbs, called flippers, with three to four nails on each flipper. The average adult manatee is about 10 feet long and weighs between 800 and 1,200 pounds. They eat a large variety of submerged, emergent, and floating plants and can consume 10-15% of their body weight in vegetation daily. Because they are mammals, they must surface to breathe air. They rest just below the surface of the water, coming up to breathe on an average of every three to five minutes. It is believed that one calf is born every two to five years, and twins are rare. The gestation period is about a year. Mothers nurse their young for one to two years, during which time a calf remains dependent on its mother. Protections for Florida manatees were first enacted in 1893. Today, they are protected by the Florida Manatee Sanctuary Act and are federally protected by both the Marine Mammal Protection Act and the Endangered Species Act OTHER LISTED SPECIES THAT MAY NEED TO BE ADDRESSED (American Crocodile (Crocodylus acutus), Florida Black Bear (Ursus americanus floridanus)) ANIMAL SPECIES The following lists of species have been observed within the Clam Pass NRPA and adjacent Pelican Bay development areas.

The most critical factor for mangrove maintenance is the hydrological regime, sometimes referred to as the surface water or surficial hydrology. This is because the surficial hydrology has both horizontal and vertical components and provides key ecological functions to the mangrove forest. With respect to the horizontal component, incoming water(both tidal and surface water run-off) into a mangrove wetland brings with it nutrients, dissolved oxygen, and marginally lower salt concentrations. Conversely,the outgoing water leaving a mangrove wetland (through tidal exchange)removes metabolic waste products (e.g., carbon dioxide and toxic sulfides) and excess salt. The vertical component refers to incoming water that percolates down into the sediment CLAM PASS NRPA MANAGEMENT PLAN(DRAFT) • Pelican Bay Services Division September 3, 2013 and root zone, and the sediment drainage, on a falling tide, which removes metabolic wastes and excess salt. It is the inflow and outflow of sea water that is critical to the ability of the mangrove forest to manage these two ecological functions and as such dissipate salts, organic matter and freshwater. It follows that anything that affects the system and alters the ability of the system to perform these functions,will, in most instances, cause stress to the system and, at some point in time, result in the death of the system, or portions of it. The Clam Bay system was originally part of a larger tidal system connected to the Gulf of Mexico by three tidal inlets; Wiggins Pass, Clam Pass and Doctors Pass. (Turrell 1996). During the early 1950's this system was isolated form adjacent bays by the construction of Seagate Drive to the south and the construction of Vanderbilt Beach Road to the north. The practical effect was to leave Clam Pass as Clam Bay's only connection to the Gulf. In 1976 culverts were placed under Seagate Drive to provide some exchange from Venetian Bay (a residential sea wall bay system) and improve water quality in the Doctors Pass area. One-way valves were placed on the pipes in 1999 but there was not enough head differential to operate the valves and they ended up acting as plugs instead. In October, 2002 these valves were removed to promote more flushing and water exchange in this southern portion of the system. Hydrologic studies indicate that the tidal flushing capacity of Clam Bay prior to the restoration dredging was limited and almost insignificant in Upper Clam Bay. The preliminary hydrographic assessment of the Clam Bay system prepared by Tackney &Associates, Inc. (August 1996) demonstrated rather dramatically that there was a significant reduction in tidal range between the middle boardwalk and Inner Clam Bay. Tackney described the flow in that area as "measurably reduced" and"very inefficient". This connecting tidal creek is the key conduit for tidal input and outflow to the northern reaches of the Clam Bay system. And its constriction and the ancillary constriction of tributaries connection to it, impact the quantity and quality of the flushing that can occur in Inner and Upper Clam Bay. As noted earlier, it is the daily rise and fall of the tide and the exchange of seawater between Clam Bay and the Gulf that are critical to the ability of the mangrove forest to export both organic matter, and excess salt and freshwater as well as receive oxygen rich water and nutrients. The greater the tidal amplitude (or tidal prism)the greater the benefit to the mangroves—more needed resources are delivered and more wastes are removed. Conversely, in the absence of surface water circulation or tidal activity, mangroves can become stressed and, in certain instances,rapidly die due to deleterious changes in the sediment or water levels. The consequence is that the root systems wither and eventually the whole tree dies. Note that the tidal exchange mechanism that is critical to the health of the mangrove forest was, within this ecosystem, seriously constrained. (Turrell 1995). Another key aspect of the surficial hydrology is the vertical location of the water level elevation relative to the mangrove sediment elevation. Specifically, the mean low water (tide) elevation has to be sufficiently lower than the mangrove sediment elevation in order for mangrove sediments to drain during low tide. A persistent high CLAM PASS NRPA MANAGEMENT PLAN(DRAFT) Pelican Bay Services Division September 3, 2013 surface water elevation stops sediment drainage and results in anoxic sediment and the accumulation of toxic waste products. It should be observed that the black mangrove forest does not require the kind of intense flushing that is more typical of the red mangrove systems in order to maximize its productivity. However,the total absence of meaningful exchange was certainly a contributor to the significant degradation of the mangrove system within Clam Bay. (Tackney 1996; Lewis pers. comm. 2008). In this context Tackney observed that even in the absence of rainfall,the average water surface elevations for the inner and upper bays were higher than the average surface elevation for the Gulf. Analysis of the tidal data indicated that average water surface elevations in the Inner and Upper Clam Bays were both elevated above the average Gulf water surface elevation by approximately 0.2 feet. This indicated that the tidal range in Inner and Upper Clam Bays was muted and that the system was receiving significant additional water through runoff and restricted capacity to drain additional inflow. In fact, during portions of the Tackney study no tidal fluctuation was noted in the Upper Clam Bay and only marginal tidal effects were observed in Inner Clam Bay. The reduced tidal ranges were also accompanied by relatively large phase lags. The phase lag is the average time delay measured in hours and minutes between the occurrence of slack(high or low) water in the Gulf of Mexico and the measurement stations. It is affected by both the distance between measurement stations and the amount and quality of hydraulic resistance of the connecting channel. The longer the distance and the higher the resistance,the more pronounced one would expect the phase lag to be. In the upper bays, high and low waters generally occurred over three hours later than the Gulf tides. These conditions indicate that the tidal creeks connecting the interior bays are hydraulically very inefficient. As a result,the upper bays are prone towards extended periods of flooding as a result of freshwater runoff and the inability of the system to drain efficiently. During Tackney's field studies of May 1996, rainfall of approximately 4 inches in three days was adequate to flood the Upper Clam Bay above high tide levels and sustain this flooded condition for over two days. Accordingly,he concluded that the creeks and bays that serve to connect the Inner and Upper Bays were significantly less efficient in the ebb tide stage than they were in the flood stage. Studies undertaken by both Lewis Environmental Services, Inc. and Turrell &Associates, Inc. would support this conclusion. (Turrell 1995). Finally, an additional attribute of the system that is directly related to tidal prism and the quantity of inflow and outflow is the question of inlet stability. Inlet stability refers to a tidal inlet's capacity to adequately scour out deposited sediments and prevent inlet closure. For a given wave environment, inlet stability is governed primarily by the volume of water(tidal prism)carried by the inlet. To remain stable, an inlet must have the characteristic that a temporary constriction in cross sectional area produces an increase in current velocities adequate to scour out the constriction. To function without mechanical intervention, the system must generate sufficient volume off water on the ebb tide to scour out the inlet naturally, otherwise the inlet will, over CLAM PASS NRPA MANAGEMENT PLAN(DRAFT) Pelican Bay Services Division September 3, 2013 time, continue to close. This is particularly true during periods of high wave activity and low tidal ranges. (Turrell 1995; Tackney 1996). The five closures of Clam Pass that have occurred in the past twenty-five years indicate that stability of Clam Pass is marginal. (Turrell 1995; Tackney 1996). Freshwater Component Under predevelopment conditions, much of the area's rainfall was held on the surface of the land in sloughs and other low areas. This water would either slowly filter through the soil to recharge the shallow aquifer or move through the mangrove community to the bay. Less than ten inches of the approximately 53 inch average rainfall is estimated to have been lost from the uplands east of Clam Bay as surface runoff. The storage capabilities of the land thus moderated surface flows,preventing extremely high flow rates during the rainy season and serving to maintain surface flow and groundwater flow during the dry season. (FDER 1981). In 1977 the Pelican Bay Planned Unit Development was established by Westinghouse Communities, Inc. The development contains a mixture of residential, retail, commercial and recreational facilities and lies east of Clam Bay. As a condition of development, Clam Bay,the area that lies west of the Pelican Bay and consists of approximately 530 acres of mixed mangrove forest and wetlands was designated as the Pelican Bay Conservation Area. As such, it was designated for conservation but with limited recreational access. This area was eventually given to Collier County and is currently classified as a Natural Resource Protection Area (NRPA). The development of Pelican Bay had limited fill impact to the Clam Bay system,but it did modify the pattern of freshwater entering the Clam Bay system. (Wilson, Miller et.al. 1996). The stormwater management system as designed, permitted and implemented at Pelican Bay employs a series of detention ponds, swales and culverts to regulate the discharge of run-off into Clam Bay. Discharge occurs almost continuously along the eastern perimeter of the conservation area. Run-off from the northern end of Pelican Bay is collected and discharged into Upper Clam Bay. Irrigation water for 27 holes of golf and landscaping in Pelican Bay is approximately 3.0 MGD which approximates 26 inches per year of additional rainfall equivalent, (Wilson, Miller et.al., 1996). When added to the average rainfall for South Florida of approximately 53 inches per year, the local area has an effective rainfall of approximately 80 inches plus annually. This is significant, particularly when viewed in the context of predictable storm events that have the potential for altering the amount of average rainfall entering the Clam Bay system. The "Pelican Bay Water Management System—Stormwater Detention Volume and Water Budget Analysis" (Wilson, Miller, Barton&Peek, Inc. April, 1996) describes the water management system as being divided into six watersheds or drainage systems. Rainfall, including irrigation, reaches the ground and either seeps into the ground or runs off to a stormwater detention area within each system. The stormwater detention plan for Pelican Bay has a standard,permitted design capacity to hold the first inch of stormwater during a 25-year storm event. The stormwater is detained for flood protection and water quality treatment. Stormwater discharge is controlled by a series of weirs designed such that the post-development CLAM PASS NRPA MANAGEMENT PLAN(DRAFT) • Pelican Bay Services Division September 3, 2013 stormwater run-off rate does not exceed pre-development rates. Stated differently, the system is designed to discharge stormwater in the development portion of Pelican Bay in the same manner that it discharged stormwater prior to development. The stormwater discharge exits the weir system for a final release into Clam Bay. Stormwater runoff from an additional 130 acres of watersheds, outside of Pelican Bay, contributes an additional and significant volume of discharge to Clam Bay. This water represents 7.9% of the total stormwater discharge to Clam Bay. As the area of Pelican Bay to the east has undergone development, it has increased the impervious surface area, with a concomitant increase in surface runoff,which is eventually discharged to Clam Bay. The daily irrigation water volume enhances the saturation of the uplands which reduces their ability to accommodate rainfall volume, thus effectively increasing surface and groundwater discharge. Groundwater discharge can be commonly observed throughout-the eastern side of Clam Bay and is discernable as a very slight sheet flow. Where this water encounters a discharge system, even one that is not operating at peak efficiency, such as Outer Clam Bay, excess water is effectively removed from the system. However, in the northern section, sheet flow was not efficiently removed due to lack of flow through the forest. Thus, it accumulated, increasing soil saturation and raising the mean water table elevation, and apparently overwhelming the black mangrove's anaerobic soil/gas exchange mechanisms. Mangroves in these areas became stressed and died. WATER QUALITY—More detail to be added from annual report During the initial environmental permitting of Pelican Bay, the agencies required water quality testing within the Pelican Bay subdivision and the Clam Bay estuary to help evaluate the impact of development on Clam Bay. The water quality-testing program was first implemented by Pelican Bay Improvement District (PBID) starting in the early 1980's. In 1991, PBID became the Pelican Bay Services Division (PBSD), a dependent Division of Collier County. PBSD continued the testing program after 1991. PBSD is currently the responsible entity for the testing program. The water quality testing is performed at several sample points within Pelican Bay and Clam Bay. The sample point locations are shown on Figure 1. There are currently ten sampling locations within Pelican Bay and Clam Bay. Sample points W-7, W-6, W-1, North Seagate, and Upper Clam Bay (UCB) are within Clam Bay, which are categorized as Class II waters by the Florida Department of Environmental Protection (FDEP). The remaining five sampling points are PB-13, E PB-13, PB-11, Glenview, and St. Lucia, are located in the stormwater treatment portion of the property(Class III waters) within Pelican Bay. • CLAM PASS NRPA MANAGEMENT PLAN(DRAFT) Pelican Bay Services Division September 3, 2013 Water quality sampling is conducted within the Clam Bay system on a monthly basis. The samples are collected by PBSD staff and transported to the Collier County Pollution Control laboratory for processing.

The FDEP permit for this activity was issued on March 28, 1996 with the companion USACOE permit being issued on April 2, 1996. The FDEP permit was modified on April 10, 1996 with the authorized work being undertaken and completed on April 17th, 1996. The practical effect of implementing this Permit was to reopen the Pass, but it was clear that without a more comprehensive strategy, this effort, standing alone, would not revitalize the Clam Bay ecosystem. A permit to improve the channel flow within defined areas of the Clam Bay system by a combination of blasting and hand excavation was issued on June 26, 1996. The work was undertaken and completed in two segments. The first channels were opened in August 1996 and the second channels were opened in November 1996. The results of these two initiatives were positive in that measurable improvements in tidal flow were discernible and with that have come improved conditions for natural revegetation. A permit was issued on January 5, 1997 to construct a portable pump and pipe system as an interim measure to divert freshwater within the Clam Bay system to the Gulf while a more permanent solution contemplated by the construction of an outfall structure was reviewed. Although this plan was never implemented and is no longer considered, it envisioned two pumps that would be operational when the water surface elevation within Clam Bay exceeded a specified threshold. The plan anticipated the direct discharge of excess water into the Gulf with the expectation that this system would augment the natural discharge through the tidal mechanism after severe storm events. Subsequently, Collier County authorized the pursuit of a ten-year permit to allow the County, or its designee (whichin this case was the Pelican Bay Services Division), to maintain Clam Pass in an open condition. The application, as filed, did not address any other issues affecting the operational characteristics of Clam Bay and essentially mirrored the 1996 Permit described in the first paragraph above. This permit was issued in 1998 and has been the guiding document for the maintenance activities undertaken in the Clam Pass system since then. It is anticipated that new DEP and ACOE permits will be applied for and implemented in conjunction with this new Management Plan. The permit duration will be coordinated with both DEP and the Corps of Engineers but is anticipated to be for a minimum period of five (5) years but hopefully for a longer duration such as the previous 10-year permits. The permits will allow for ongoing maintenance and enhancement activities to continue along with occasional, modest removal of material by dredging within a discreet area of Clam Pass in order to maintain the existing tidal regime within the system. Any changes to the submitted dredging scope or other new management initiatives will be reviewed and permitted (as necessary) under separate applications. Additional investigations which may be undertaken at a later date to look at, for • CLAM PASS NRPA MANAGEMENT PLAN(DRAFT) Pelican Bay Services Division September 3, 2013 example, additional faunal investigations, more in-depth water quality concerns, dredging outside of previously approved templates, or other issues that may arise as a result of stakeholder discussions could also necessitate additional permitting. This Management Plan is specifically tasked to maintain the improvements and benefits already realized and to insure that the restoration success observed to date is continued.

Discuss Draft Clam Bay Management Plan-Chapter 6(Received 9/3/2013) Page 1 of 3 6.0 Management Plan Goals and Objectives The following goals and objectives for the management of the Clam Pass Natural Resource Protection Area were developed in accordance with the directives of the Collier County BOCC and the Pelican Bay Services District. The goals and objectives were formed in conjunction with stakeholder input and are based on the management issues present in the preserve as well as the purposes for which the land is help in public trust. The document goals set forth in this plan should not appreciable change over time but the management techniques and activities proposed may be modified based on ongoing coordination with stakeholder and user groups or when management objectives are not being met. Management concerns are addressed in the following sections along with the management techniques or activities proposed for addressing those concerns. The ability to implement specific goals or objectives presented in this plan will be based on funding and staffing availability. The following goals were identified during the stakeholder and PBSD committee meetings. Goal 1 - Provide sufficient tidal exchange to maximize benefits to the estuary while minimizing environmental impacts. Goal 2 -Maintain and protect the native floral and faunal communities Goal 3 -Manage and improve water quality Goal 4 -Address recreational uses with emphasis on passive recreation Goal 5 - Improve community awareness and involvement GOAL 1 - Provide sufficient tidal exchange to maximize benefits to the estuary while minimizing environmental impacts. A. Establish appropriate metrics to determine when dredging is necessary. Monitoring of the Pass and internal waterways will provide information to determine when and how much dredging is necessary. Bathymetric surveys of cross-sectional areas of the Pass, Tide gauge data, and biological indicators can all be used to trigger dredging events as needed. Dredge for tidal exchange benefit only, not for navigation or beach renourishment. B. Minimize dredge footprint(s) to the least damaging practicable alternative. Dredging should be conducted only in those areas necessary to achieve the desired flow improvements. Current survey data and cross sectional areas will be examined before establishing the dredge footprint for each dredging event. September 5,2013 Clam Bay Committee of the Pelican Bay Services Division Board 3. Discuss Draft Clam Bay Management Plan-Chapter 6(Received 9/3/2013) N. Page 2 of 3 C. Maximize the dredge interval as much as possible while maintaining environmental standards. While dredging smaller amounts may be less damaging in the short term, the potential need to dredge more often may offset that benefit. Develop a scope which balances the tidal exchange benefits while minimizing the number of times dredging is needed. GOAL 2 -Maintain and protect the native floral and faunal communities A. Establish baseline floral and faunal resource populations Conduct floral and faunal surveys as needed to document baseline conditions and establish parameters upon which future survey efforts can be compared. B. Protect Listed Species Identify listed species utilization of the NRPA. Provide buffers around nesting activities to prevent adverse anthropogenic impacts during nesting seasons. Increase public awareness as necessary through signage or other efforts to minimize adverse impacts. C. Protect and maintain vegetative communities Regularly inspect habitats for exotic vegetation. Remove exotics when observed without damaging integrity of native communities. Conduct periodic monitoring of habitats to track changes over time. D. Protect and where possible enhance wildlife utilization of the NRPA Conduct periodic monitoring of wildlife populations within the NRPA boundaries. Identify utilization priorities and enhance protection as needed to insure that continues use is viable. GOAL 3 -Manage and improve water quality A. Insure adequate freshwater inputs Freshwater inputs are an important factor in maintaining a healthy mangrove system. Mangroves typically thrive in estuaries, where salt and freshwater mix. The reduced salinities lessen the energetic burden involved in excreting or excluding salt while the presence of some salt prohibits different aquatic vegetation from establishing and out-competing mangrove species. September 5,2013 Clam Bay Committee of the Pelican Bay Services Division Board 3. Discuss Draft Clam Bay Management Plan-Chapter 6(Received 9/3/2013) Page3of3 Freshwater flows into this system provide valuable flushing activities in the northern reaches where tidal exchange is decreased. Freshwater flows also contribute to the Pass stability by adding outgoing flow which helps to keep the pass open. Activities within the development area will be examined to insure that adequate flows into the estuary are maintained. B. Coordinate with adjacent developments to improve upstream inputs. Adjacent developments will be made aware of the ongoing water quality conditions of the NRPA and provided information on how they can help maintain or improve their stormwater contributions into the system. C. Develop a monitoring program to build on past data and provide basis by which to make future water quality related decisions. Develop a long term monitoring program to track water quality conditions within the system. Include the means to track inputs into the system. GOAL 4 -Address recreational uses with emphasis on passive recreation A. Maintain access and required facilities for intended uses Conduct periodic inspections of access points and visitors facilities. Conduct trimming of vegetation as needed to maintain boardwalk access and open waterways for canoe and kayak passage. B. Maintain existing signage or develop new signage to educate visitors Site specific signage can developed, or maintained where already present, to educate visitors on plant identification and general habitat information. Also included should be information on how to help preserve habitats and prevent unwanted impacts to the plants and animals sharing the area. GOAL 5 -Improve community awareness and involvement Continue to foster stakeholder involvement through public meetings, information dispersal, and periodic management and monitoring plan reviews. ° September 5,2013 Clam Bay Committee of the Pelican Bay Services Division Board 5.
