<br />The State of Florida established the CCCL along Florida's sandy beach shorelines to <br />delineate those areas subject to erosion or other adverse impacts during a 100-year storm. Specific <br />elevation and construction requirements are enforced by the State seaward of the CCCL. With <br />the exception of Bay County, the portions of the CCCL in the study area were adopted by the <br />State between 1982 and 1991 and reflect anticipated 100-year storm impact zones. However, the <br />pre--Opal CCCL in Bay County was essentially unchanged from a 50-foot setback line established <br />by the State in 1975 and did not include all areas subject to 100-year storm impacts. Mer <br />Hurricane Opal, the State adopted a revised CCCL for Bay County on an emergency basis. The <br />new line is 100 feet landward of the pre--Opalline and became effective on October 16, 1995. <br />Reconstruction of many damaged or destroyed structures along the Bay County shoreline will <br />now be subject to CCCL construction requirements. <br /> <br />The FDEP has also completed its own studies that predict 100-year stillwater elevations along <br />the Gulf of Mexico shoreline. FDEP studies for the reach between E5cambia and Bay Corm ties <br />generally show 1 DO-year stillwater elevations ranging between 11 feet and 12 feet NGVD. The 5- <br />foot to (}'foot difference between FDEP and NFIP 100-year stillwater levels is attributed to the <br />inclusion of dynamic wave setup by FDEP. <br /> <br />A comparison ofV-Zone boundaries and the location of the State's CCCL had not been <br />completed at the time this report was prepared (a comparison is expected by late 1996). However, <br />the State's foundation and elevation requirements seaward of the CCCL (i.e., pile penetration <br />requirements and lowest floor elevations) are known to be more stringent than NFIP V--Zone <br />requirements. likewise, the State's wind load requirements seaward of the CCCL are known to be <br />more stringent than the wind load requirements of the Standard Building Code. According to the <br />FDEP (1995), no m~or habitable structures located seaward of the CCCL and permitted by the <br />State under current standards sustained significant structural damage during Hurricane Opal. In <br />contrast, the FDEP reported that over one-half of the pre-exi5ting major habitable structures <br />seaward of the CCCL (i.e., structures either not permitted by the State or constructed prior to <br />State permitting requirements) sustained structural damage during the storm. <br /> <br />1-4 <br /> <br />INTRODUCTION <br />
