City of Punta Gorda Adaptation Plan Southwest Florida Regional ...

example

example of how CoBRA has worked, where the presence of thousands of platted lots with vested development rights has discouraged development, giving time for a voluntary state land acquisition program to acquire about 97% of this state park from private land owners. In other parts of the state, CoBRA areas with easier access have been developed, but the unavailability of federal subsidies makes beach nourishment unlikely. Lack of federal subsidies for sewage treatment has limited the density in still other areas. The unavailability of flood insurance and federally backed mortgages also discourages development. Even though the other parts of the Federal Flood Insurance Program encourage shore protection, the program does have a component that also encourages retreat. Specifically, the repetitive loss program (a repetitive loss consists of two flood insurance claims on the subject property) offers a 50/50 federal/local match to buy the parcel for preservation. Otherwise a repetitive loss owner can match 50% of the cost to raise the structure to prevent further flooding which is a form of encouraging shore protection. Florida State Policies and Programs Similar to the federal policies, no state policies specifically address the issue of sea level rise, but many policies are already in place to deal with consequences. These policies are included in the Coastal Construction Control Line Program, the Beach Erosion Control Program, the Coastal Building Zone, Strategic Beach Management Plans and Environmental Resource Permits. Florida Policies that Encourage Shore Protection The Florida Beach and Shore Preservation Act was enacted by Florida‘s legislature to preserve and protect Florida‘s beach and dune system. Beaches and dunes are the first line of defense against storms, acting as a buffer between the sea and coastal development. One of the programs authorized by the Beach and Shore Preservation Act to be an essential element in the protection effort is the Coastal Construction Control Line (CCCL) Program (Beach and Shore Preservation Act, Florida Statutes Chapter 161). The CCCL Program was designed to protect Florida‘s beach and dune system from irresponsible construction that could weaken, damage, or destroy the health of the dune system. Structures that are built too close to the sea can inhibit the beach and dune system from its natural recovery processes and can cause localized erosion. Improperly constructed structures are a threat to other nearby coastal structures, should they be destroyed by storms. The CCCL Program gives the state the jurisdiction to apply stringent siting and design criteria to construction projects seaward of the control line. The CCCL is not a setback line, but is rather a demarcation line of the state‘s authority. The CCCL is marked at the landward limit of coastal areas that are subject to the effects of a 100-year storm surge. While wind and flooding may intrude further inland than the 100-year storm surge area, effects landward of the CCCL are considerably less than seaward of it. Seaward of the CCCL, the State prohibits the construction or siting of structures that would cause a significant adverse impact to the beach and dune system, result in the destabilization of Adaptation Plan Page 206

the system or would destroy marine turtle habitat. To meet these requirements, structures are required to be located a sufficient distance from the beach and frontal dune and must also be sited in a way that does not remove or destroy natural vegetation. The CCCL also requires all structures to be constructed to withstand the wind and water effects of a 100-year storm surge event. This involves creating structures that meet the American Society of Civil Engineering 7- 88 Section 6 wind design standard for 110 mph winds (115 mph for the Florida Keys). Water design standards include a foundation engineered to withstand a 100-year storm event, including the effects of surge, waves and scouring. There is no prohibition of rebuilding under the CCCL Program. Due to the effects of erosion, the CCCL Program discourages the construction of rigid coastal armoring (seawalls) and instead encourages property owners‘ use of other protection methods, such as foundation modification, structure relocation and dune restoration. Another similar endeavor to regulate coastal construction is the Coastal Building Zone (CBZ). The CBZ was established as part of the Coastal Protection Act of 1985 to protect coastal areas and to protect life and property. The CBZ is similar to the Coastal Construction Control Line program in that it is a regulatory jurisdiction, rather than a setback line. The CBZ envelopes land from the seasonal high water line to 1500 feet landward of the CCCL. In those areas fronting on the ocean but not included within an established CCCL, the Coastal Building Zone includes the land area seaward of the most landward V-Zone line, as established by the National Flood Insurance Program‘s (NFIP) flood maps. The V-Zone is an area likely to experience a wave greater than three feet high with storm surge, or areas within the 100-year storm event used by the CCCL program. Local governments, rather than the state, enforce the Coastal Building Zone as a part of their building codes. Within the CBZ, new construction is required to meet the Standard Building Code 1997 wind design standard of 110 mph (115 mph for the Florida Keys). As for water standards, structures are required to meet NFIP requirements or local flood ordinance requirements, whichever are stricter. Foundations must also be designed to withstand a 100-year storm surge. CBZ construction standards are less stringent than CCCL standards. This is due to the fact that NFIP flood maps have lower base flood elevations for 100-year storm events than do CCCL studies. Another State effort to protect Florida‘s beaches, authorized by the Beach and Shore Preservation Act, is the Beach Erosion Control Program (BCEP). The BECP is the primary program that implements the Florida Department of Environmental Protection‘s beach management recommendations. The BCEP was created to coordinate the efforts of local, state, and federal governments in protecting, preserving and restoring Florida‘s coastal resources. One of the activities of this program is the offering of financial assistance to counties, local governments and other special districts for shore protection and preservation efforts. The BECP will provide up to 50 percent of project costs. The mix between federal, state and local funds is different for each project. Beach management activities eligible for funding from the BECP include beach restoration and nourishment activities, project design and engineering studies, environmental studies and monitoring, inlet management planning, inlet sand transfer, dune restoration and protection activities, and other beach erosion prevention related activities.
