CURRAN Coastal Zone Management Technician (i) ENVIRONMENTAL SECTION COMMUNITY DEVELOPMENT DIVISION , ) COLUER COUNTY GOVERNMENT COMPLEX 3301 TAMIAMI TRAIL EAST NAPLES. FLORIDA 33942-4977 PREFACE Overview Collier County's coastal zone, defined for administrative purposes as that area of the County on the Gulf side of U.S. 41 (the Tamiami Trail). encompasses 328 square miles of coastal barrier, bay, wetland, and maritime upland habitats. The coastal zone stretches 57 miles from the northwest to southeast and varies in width from 2 miles at the north county line, to 12 miles in the vicinity of Marco Island and 8 miles near the southern county border. Collier County's coastal zone, which makes up 16 percent of the County's total land area, is inhabited by 38.800 people (1980 census), 45 percent of the County's population. An addi- tional 29,300 people live within 5 miles east of U.S. 41. In total. 79 percent of the county's population is found within 10 miles of the Gulf of Mexico. ) The County's coastal zone is characterized by both developed and undevel- oped areas. Of the 328 square miles in the coastal zone 67 square miles (21 percent) are developed. Of the remaining 261 square miles 123 square miles (37 percent) are undeveloped and preserved as Federal (Everglades National Park, Rookery Bay National Estuarine Sanctuary), State (Faka- hatchee Strand, Collier-Seminole, and Delnor-Wiggins State Parks and Barefoot Beach State Preserve), and County (Tigertail and Clam Pass Beach Parks) resource management and protection areas. The remaining 138 square miles (42 percent) are undeveloped and in private ownership. Unlike most of the rapidly developing counties in South Florida, Collier County is unique in that the great majority of its coastal zone is still in its natural state. Hundreds of thousands of acres of coastal barriers, wetlands, bays, and marine grassbeds are still relatively undisturbed, much as they have been for thousands of years. It is these areas that have made Collier County so aesthetically attractive. If properly managed they will continue to function in this respect. ) Of equal importance, however, are the natural resources of these undeveloped regions of the coastline areas which are ecologically vital to both the County and southwest Florida. The coastal barriers, if they remain unaltered, serve as a first line of defense against the sea. Storm surge damage, coastal flooding, and erosion of the mainland can be alleviated or slowed by a functioning, natural system of coastal barriers. The wetlands, shallow bays, and marine grassbeds are other important parts of the coastal ecosystem. The mangrove forests (those in Collier County being some of the largest, undisturbed systems in the United States and one of the best developed in the world) and associated marshes provide the organic materials and detritus that form the basis of the coastal food chain and support the abundant shellfish and finfish resources of southwest Florida. The unaltered coastal ecosystem not only functions as a haven for birds, fish, and other wildlife. but may also provide necessary refuge for those species that have been driven from adjacent, heavily altered or extirpated coastal systems. The undisturbed natural systems of Collier County form the keystone for the south Florida ecosystem. The coastal zone links the estuarine systems of Lee and Monroe County while the vast, unspoiled eastern area of the County connects the coastal and interior wetland systems with those of Dade and Broward Counties. Almost half of the unaltered coastal zone in Collier County is under the ownership and/or management of Federal, State, or Local agencies for the sole purpose of protecting the natural systems. Although this is gratifying, it is important to remember that the other half of the undisturbed coastal area is in private ownership. In addition, both the private and the managed coastal areas are bounded by uplands that are either developed or projected for future urban or agricultural dev- elopment. Activities undertaken in the private areas of the coastal zone or on adjacent upland property, if not properly planned, could result in the degradation of our remaining undisturbed coastal areas in only a few decades and the loss of their resources. In a recent position paper R. A. Livingston wrote that "if history is our guide, one basic problem lies in public acceptance of almost any level of environmental deterioration as long as it occurs gradually enough". To safeguard the coastal zone resources of Collier County from gradual deterioration and to ensure their continuing function as a vital part of the southwest Florida ecosystem, positive and direct steps must be taken. Predominant among these must be the implementation of a program to ensure that all future land use activities proposed for the coastal zone are designed to be totally compatible with, or at least not inimical to, the natural resources and the associated recreation values of the County's un- disturbed coastal areas. Collier County Coastal Zone Management Program ) The coastal zone is one of Collier County's major assets. Abundant_ natural resources, ample recreation opportunities. and popularity as a homesite for many seasonal and full time residents are factors of the coastal zone well recognized by the Board of County Commissioners, the County staff, and-many local conservation and business groups. For these reasons the community as a whole has supported past and present coastal zone management activities in Collier County. With the support of the Board of County Commissioners and grants from the Office of Coastal Management, Florida Department of Environmental Regulation, and the Erosion Control Program, Florida Department of Natural Resources, the Collier County Natural Resources Management Department is developing a County Coastal Zone Management Program. A major goal of this program is the protection of the natural resources of Collier County's coastal barriers, bays, and wetlands and the management of coastal development in order to ensure that future land-use activities will not degrade these resources. The Program is a continuous. multi- year project involving, research, implementation, and environmental protection activities. Progress to date includes data incorporated into the following Technical Reports: ) Technical Reports 83-1, 83-2, 83-3 Beach Management Planning and Implementation Strategies at the Local Level The Beach in Collier County: A Model in Southwest Florida Drafts plans for beach and coastal barrier management in Collier County; describes major components and imple- mentation of Collier County Coastal Zone Management Pro- gram; identifies Collier i ; ) A Resource Management Program for the Coastal Barriers of Collier County, Florida Technical Report 84-1 Natural Resources Management Plan Technical Reports 84-2. 84-3 Coastal Barrier Resources Coastal Estuarine Resources ) Technical Report 84-4, 84-5 Coastal Zone Management Units: Data Inventory and Analysis Coastal Zone Management Units: Atlas Technical Report 84-6 Draft Ordinances for Protection of Coastal Ecosystems ) iii.

Upcoming Program activities include: (1) The design and implementation of a development review procedure that closely ties the permitting of a land-use activity, proposed in or adjacent to the currently undeveloped regions of the coastal zone, to a specific ecological community, its resource values, and its limiting biological and physical factors. The procedure will be designed to ensure that only those activities compatible with habitat values and functions, or designed to minimize adverse impacts on those values, will be allowed (project funded by D.E.R. Office of Coastal Management); and (2) The continuation of dune restoration and protection activities at all County beach parks and access points. The latter proj ect involves the removal of exotic plant species, the reconstruction and revegetation of dunes damaged by storm activity or visitor use, the construction of back dune feeder walkways and dune crossovers, and the placement of signs and low profile fences to maintain the restored dunes (project funded by the D.N.R. Erosion Control Program) . The results of these and other proj ects conducted under the County Coastal Zone Management Program will be the subject of future Technical Reports prepared by the Natural Resources Management Dep- artment.

Mans' activities at the land-sea interface can ad- versely impact its functional and economic value. Consequently the beach has been the site of both State and Federal managment efforts. Beach ) conditions and the intensity of land development vary tremendously along the coast. Since it is difficult for state-wide agencies to be familiar with local beach characteristics and management goals, local programs are needed to contribute detailed first-hand data to the review process. Since beach communities have the most to lose from the unguided develop- ment of beaches, it is essential that they formulate their own objectives and policies pertaining to beach management and protection. Federal and. State agencies encourage and aid long-range beach management planning and implementation at the local level. Over the ) last ten years the Federal government has awarded planning funds to coastal states through the National Oceanic and Atmospheric Administra- tion Office of. Coastal Zone Management. Some of these funds have been utilized by regional agencies in developing state-wide programs while others have been contracted to municipalities to support local programs. The statutory authority for the formulation and adoption of local beach management programs in the state of Florida lies in Part II of Florida Statutes Chapter 161, the Beach and Shore Preservation Act. This act designates the Board of County Commissioners as the local shore and beach preservation authority and empowers a county to carry out those investigations necessary to "plan a logical and suitable program for 1. comprehensive beach and shore preservation within its county." The Act -further grants the County Commission the broad regulatory powers neces- sary to achieve this goal as well as the authority to fund local programs by the levying of taxes and/or the issuance of bonds. BEACH MANAGEMENT IN COLLIER COUNTY Collier County serves as an excellent model of beach management actions that can be undertaken at the local level. ' Early beach resource management studies in the Naples area were conducted by the Army Corps of Engineers (1972) and Wanless (1975). A Naples beach study, authorized by the City Council, was completed in 1980 (Suboceanic Consultants, Inc. 1980). ) The first beach management attempt at the County level was made in 1973 with the passage of a coastal setback ordinance. This ordinance declared it unlawful to excavate. alter ground elevation, or build a structure within one hundred feet of the vegetation line or one hundred and fifty feet of the mean high water line without first obtaining a variance from the Board of County Commissioners. It further stated that variances would not be granted for any activity within fifty feet of "any point or line of erosion that has existed on the applicant's property within the past twenty-five years". In 1975 the Collier County Board passed a Coastal Construction Control Line Ordinance. This Ordinance rescinded the previous setback requirements and adopted in their place the fixed Coastal Construction Control Line recommended by the State. In addition it provided for the ) 2. issuance of variances for activities seaward of the Line and for appeals of the location of the Line. Between 1975 and 1981 several attempts were made to revise the ordinance. Although some amerl(:!ments were passed, the most important revision was never presented for Board approval. This revision to adopt a coastal construction code was withdrawn because of criticism that it was not based on a detailed study that provided supportive data and that it was not site-specific in nature. Realizing the value of the County's beach . resources and citing the lack of specific criteria for CCCL variance evaluation, the Board of County Commissioners in 1981 directed the staff of the Community Devel- opment Division to undertake those actions necessary to develop a com- prehensive, long-range beach management program for Collier County. ) In 1981 the Division submitted an application for funds from the D.E.R. Office of Coastal Management to assist in the development of such a program. Once received these funds were used to hire graduate-level interns to work with the County Environmentalist in the in-house prepar- ation of a beach management program pursuant to Part II of F.S. Chapter 161. This project has been underway for eight months. Additional D.E.R. funds have been made available to carryon the development of this program and its implementation. COLLIER COUNTY BEACH ~~AGEMENT PROGRAM The Collier County Beach Management Program involves a multi-faceted approach to natural resource management. It recognizes the need for ) 3. " ! three different yet inter-related components: the Data Base, the Haster Plan. and Implementation Aids. The program is designed to cover all aspects of beach managemcnt in Collier County yet bc flexible and re- sponsive to additional data input, changes in shoreline recession rates. and public opinion. The program is holistic. It covers the entire beach system of Collier County including the intertidal and supratidal beach zones, dunes, and inlets. DATA BASE The essential first step in any natural resource management program is the collection of resource information and the compilation of a data base upon which subsequent management decisions can be made. This approach is commonly used by the National Park Service in the management of their lands (Godfrey and Benedict, 1977). The Collier County Beach Data Base consists of three parts, the Resource Inventory, the Historical AnalysiS, and the Synthesis (Figure 1). Resource Inventory The Resource Inventory provides County-wide information on the current status of both natural and man-made beach features. Specifically the Resource Inventory provides data on the following: Beach Width and Condition - Graphic representation of the variabil- ity in beach width in Collier County, the setback of engineered structures and land development activities, and the setback of the Coastal Construction Control Line from the mean high water shore- line; Natural Vegetation and Wildlife Inventory distribution of vegetation and wildlife on of the diversity and the barrier beaches; Inlet Condition - Current status of resources associated with inlets such as fishing and navigation; ) Land Use Classification - Separation of the barrier coastline by ownership and types of uses such as commercial, residential, and public recreation; 4. ) . z .

Survey of Structures - Mapping and description of the effects of engineered beach front protection structures such as seawalls, revetments, and groins; Beach Access and Recreation Conditions - Location of beach access points and assessment of the recreation quality of the beaches in the vicinity. In summary, the Resource Inventory describes what features occur along the beach and where they are found. Historical Analysis Information on the current beach resources, both natural and man- made, is not sufficient to make enlighter:ed management decisions. In addition, an understanding of beach processes and of changes in the beach ; ) over time are necessary. The Historical Analysis provides information on these aspects of the Data Base. Specifically it includes data on: Climatic-Hydrographic Setting - Summary of the effect and importance of winds, waves, and tides in influencing the dynamics of Collier County's beaches; Shoreline Changes - Systematic measurement of the shoreline position at 73 reference points from 1885 to 1981. Data were used to calcu- late cumulative shoreline changes, beach erosion rates, and rates of shoreline fluctuation in different parts of the County (Figure 2); Inlet Dynamics and Alterations - Mapping of sequential changes in the position .of tidal passes and erosion or accretion of adjacent shorelines. Includes history of modification by jetty construction or dredging; Beach Profiles 1973 - 1982 - Selected profiles made by D.N.R. in 1973 were re-established and resurveyed in 1982 (Figure 3); Littoral Transport - Graphic representation of littoral drift rates from Walton (1973) based on littoral transport theory, shipboard wave observations in the Naples area, and the effect of local beach orientation on littoral transport rates; L) 6. ~ / ( Mrlf'~ I i:!"! t;AJ I':] E::I ~ o 1 2 J 4 5 400 C 0 '~ CJ) '\ 0 ~ 200+ W c o -+-- ~ () () <( ) (ft) KEY Cumulative Shoreline Changel 4 1885 - 1981 A 1927 -1981 · 1962 - 1981 o 1973 - 1981 ) Figure 2.

In short, the Historical Analysis describes what has happened along the Collier coastline in the past, what the controlling processes are, and what future changes can be expected. Synthesis Data contained in the Resource Inventory and the Historical Analysis provides the beach manager with a powerful tool. The synthesis of these two components endows the Data Base with a predictive ability. Although nothing can be forecast with certainty, this is the best and perhaps the only way for the beach manager to look into the future while reviewing present day petitions. The synthesis of the Resource Inventory and the Historical Analysis ) also permits the identification of discrete beach segments along the County's coastline (Figure 4). These beach segments, which are delimited according to -their resource features and their predicted shoreline changes, are the most significant end-product of the Data Base with regard to beach management. The technique of identifying and separating beach segments for management purposes has been applied previously by Pilkey et al (1978) and Harvey (1982). Beach segment maps with site- specific information on beach/barrier characteristics, shoreline migra- tion history, recreational value, and hazard potential (Figure 5) emphasize the distinct nature of different portions of the Collier County coastline and the need to treat each separately in terms of management. MASTER PLAN The second component of the Collier County Beach Management Program ) is the Master Plan (Figure 6). It relies on and builds from the Data 9.

As opposed to the Data Base which states facts, the Master Plan puts forward the County's goals and objectives relating to beach management. In addition it recommends specific policies on which to base decisions regarding permit applica- tions and outlines specific actions to be undertaken to enhance the County's beach resources. In short, the Master Plan presents a concensus on how the County wishes to handle its beach resources and what steps will be taken to develop an effective management program to accomplish County goals. The Master Plan is divided into three parts, the Goal, the Objec- tives, and the Recommendations. The first part describes the current management status of the beaches and the justification for a Beach Management Program. It then presents the Goal of the Master Plan which ,) is to "manage the beaches, dunes, and inlets of Collier County to insure the protection and maintenance of these system's functional and recrea- tional values.1I Following the justification of the program and the presentation of a unifying goal, the Master Plan sets forth the objectives of the Beach Management Program. The Program deals both with beach resources and beach activities, and therefore both resource management objectives and activity objectives are needed. Resource objectives cover the beach, the dunes, and the inlets while activity objectives cover construction, recreation, and restoration. An example of a resource obj ective is: Strictly protect all remaining coastal strand vegetation for its ability to act in storm protection and for its habitat value for native wildlife. Taking beach construction as an example, an activity objective is: ) 13. Prohibit any shorefront construction activity that would result in a structure (either habitable or protective) that ~..ould interfere in the onshore-offshore or the alongshore transfer of sand. Once general beach management objectives have been formulated they are applied to the data base to yield recommendations. Recommendations not only address policies to be followed while evaluating beach permit applications but also suggest actions to be taken for the benefit of the beach system. As were the Master Plan objectives, the recommendations are broken down into resource-specific and activity-specific categories. The resource-specific recommendations are grouped' by beach, dune, and inlet resources while the activity-specific recommendations are classi- fied according to construction, recreation, and restoration activities. Realizing that the evaluation of a petition depends on the location of the site, its current resource utilization. and its shoreline process ) characteristics, area-specific recommendations are also presented for different parts of the Collier County coastline. This systems approach to beach management is accomplished by the superimposition of resource and activity recommendations upon the beach segments delineated in the Data Base. Beach segments are grouped together into management units highlighting their distinct resource characteristics and functional interdependence. Once grouped, management decisions can be made in keeping with the characteristics of the entire sand sharing unit, elimi- nating the danger of piecemeal, project-by-project evaluation. The Vanderbilt Beach area is a perfect example of a discrete unit that must be managed accordingly. The area is characterized by numerous structures built precariously close to mean high water and by a rela- tively high rate of shoreline retreat. In addition there exists a 'J conglomeration of poorly integrated seawalls, revetments,and unfortified 14. shoreline areas. Clearly, permit applications should be treated differ- ently at this location than at less intensely developed areas with wide setbacks. Recorr.mended policies for petition review in the Vanderbilt Beach area include: Permit the construction of hard, shoreline protection structures only where necessary to protect buildings constructed too close to the beach; however, take those steps necessary to insure that those structures are the minimal needed and that they are constructed in such a way as to reduce adverse impact on the adjacent beach; Where riprap is placed as a protective structure insure the public's right to use the seaward and adjacent beach areas when high waters prohibit pedestrian passage seaward of the structure by requiring the construction of riprap bypass stairs and walkways; Prior to permitting the repair of storm damaged structures, require realignment to better integrate the structures with adjacent areas. In order to insure that each unit is managed as a whole system, separate, unit-wide beach plans should be formulated in the future for each recog- ) nized area. Unlike the Data Base which is an in-house document, the Master Plan must be prepared with the input of the general public. The Plan is proposed by County staff and modified as necessary following workshops with representatives from both the private and professional sector. The final step in the preparation of the Plan is adoption by the Board of County Commissioners. When adopted, the goals, objectives, and recom- mendations become the official County Plan for beach management. To insure its recognition, copies of the Master Plan must be distributed to all appropriate State and Federal agencies. IMPLEMENTATION AIDS As parts of the Collier County Beach Management Program the Data Base provides the facts on beach resources and processes while the Master ) 15. ) ) I' Plan sets County policies regarding the management of the beach system. In addition to these two components. a successful beach management program must have the tools necessary to implement the Master Plan and to maintain and update the Data Base. The preparation of these tools or implementation aids is the third component of the Beach Management Program (See Figure 7). At present, six discrete implementation aids are being prepared for the Beach Management Program. These are: 1. Beach Monitoring Program In order to periodically update the County Data Base. permanent beach monitoring stations have been set up along the County's coastline. Both beach profile stations and photographic reference stations have been established. Profile stations were established at the location of 1973 DNR profiles to assess seasonal and annual changes in beach slope and in the loca- tion of the vegetation line. Photographic reference stations are designated camera sites selected to provide a pictoral record of shoreline change in Collier County. All stations are particularly useful for the evaluation of rapid shoreline changes following major coastal storms; 2. Dune Management Project - In order to carry out the objective of dune protection in Collier County a dune management plan has been prepared for all public beach parks and access points. Depending on need and location, the project includes dune recon-struction, coastal strand revegetation, the removal or thinning of Australian pines, the construction of dune crossovers and surficial beach walkways, and the erec tion of fences. signs. or other barriers to prevent pedestrian traffic from damaging sensitive dune areas; 3. Coastal Construction Ordinance and Performance Bond System A maj or revision to the County's Coastal Construction Control Line Ordinance is necessary to implement the site-specific objectives and recommendations of the Master Plan and to provide a legal basis for their enforcement. Along with the revised ordinance, a per- formance bond system is being set up to require the posting of bonds to cover the cost of restoring beach and dune resources lost due to construction errors or negligence; 4. Administrative Rules and Procedures - In order to insure compliance with all aspects of the adopted Haster Plan, administrative rules and procedures are being set up within the County's governmental system. Such rules deal with the County-wide administration of beach-related petitions and follow-up inspections. The procedures mandate close coordination between the County's Building, Zoning, and Engineering Departments; 16. , ~ ~ ) ~-----------,,-, I I I . I I . I I I I I I I : :> : , 0. . I 0.

Undeveloped Barrier Beach Use Guidelines - In Collier County unde- veloped barrier beaches are classified as "Special Treatment" under the Zoning Ordinance. This zoning overlay system recognizes the barrier beaches' ecological values and functional characteristics and requires the approval of site development plans prior to land alteration. Although these regulations are designed to permit only those activities that are compatible with the ecological characterist ics of the areas. the lack of specific construction guidelines creates confusion for the public and inconsistency in County permitting. For this reason, barrier beach use guidelines are being developed as a part of the Beach Management Program; 6. Coastal Structure Performance Standards - In order to provide for the effective and rapid review of coastal construction petitions and to let the land owner and developer know what is and is not acceptable, coastal structure performance standards are being prepared for Collier County. These standards. to be drawn up in cooperation with the County Building and Engineering Departments and with local professionals, will be based on coastal codes first developed in 1979. The standards cover both habitable and protec- tive structures. These are not all the tools necessary for the effective implementation of the Master Plan. As additional needs arise, new implementation aids will ) be developed. SUMMARY The beach system is a valulable resource that needs to be managed to insure its protection and continued maintenance. To accomplish this a three part Beach Management Program is being developed for Collier County (Figure 8). The program contains: (1) a Data Base that describes what resources exist, where they are found. and what processes control their change; (2) a Master Plan that presents local beach management goals and objectives as well as recommends policies for reviewing permit applica- tions and actions for resource enhancement; and (3) Implementation Aids that provide the tools necessary for the effective implementation of the ) program. 18.

Feedback The Beach Management Program is designed to protect the entire beach system, the intertidal and supratidal beach zones, the coastal strand and dune communities, and the inlets. It is a dynamic program that will be modified and amended as additional data is obtained. The goal of the Program is clear. to protec t the resources of the beach system for their functional and recreational value. Beach protection is in the interest of all County residents. There are a number of different opinions on how to achieve this. Only a close interaction between all citizens (Figure 9) will result in a Beach ManagetiJent Program with the strength to carry out this goal. ) ) 20. CIl ... C1I <1;l ~ U 0 ... C1I <:) w E E ....
