DESCRIPTION AND CONDITIONS: On March 3, 1987, the Governor and Cabinet, acting as head of the Florida Department of Natural Resources, adopted Rule 16B-26.018, Florida Administrative Code, that moved the Indian River County Coastal Construction Control Line (CCCL) approxi- mately 200 feet west of the line that was established in 1981. The CCCL is administered as a line of regulation by the State, whereby construction is authorized seaward of the line from time to time. The County, on the other hand, had administered the CCCL as a line of prohibition and historically not authorized construction seaward of the CCCL. When the State moved the CCCL landward by approximately 200 feet last year, the County realized that the continuance of an absolute prohibition of construction seaward of the CCCL was not reasonable, and on March 10, 1987, the Board of County Commissioners adopted several amendments to the local code to permit the construction of State approved houses and other structures seaward of the CCCL. At this Hearing, the staff advised the Commission that additional revisions would be necessary to the Tree Protection Ordinance to permit the continuation of County policy that prohibited most construction seaward of the "old" control line) and the Commission authorized additional revisions. The proposed ordinance officially designates the "old" 1981 CCCL as the County Dune Stabilization Setback Line and continues the present policy of general County prohibition of Construction and dune vegetation protection seaward of the 1981 control line. In recent years, the State has been in a process of analyzing each coastal County's CCCL and revising the location of the CCCL for a few counties each year. The "new" or relocated Coastal Construction Control Lines are the result of numerous studies, including computer modeling that indicate that storm erosion damage is likely to extend further inland than was previously thought. This fact has dictated that the CCCL be moved a significant distance landward of the old line that was established in 1981. The Planning and Zoning Commission, at the February 11, 1988, Planning and Zoning Commission Meeting, voted unanimously to recommend approval of the proposed ordinance to the Board of County Commissioners. ALTERNATIVES & ANALYSIS: The Proposed ordinance takes the "Old" Control Line and desig- nates it as the County Dune Stabilization Setback Line. The old control line is utilized since that line approximates the landward limit of the primary dune along with typical Coastal Strand vegetation including cabbage palm, sand live oak, seagrape, red bay, saw palmetto, sea purslane, beach morning- glory, seaoats, and sanbur, among many others. Adoption of the proposed ordinance will not change county policy from the way it has been applied to coastline development for many years. Within the last year, the staff has examined several legal and technical considerations associated with the proposed ordinance, and the proposed ordinance changes are new in a form ready for adoption by the County.
