a. Communities, coastal barriers and Otherwise Protected Areas (OPAs) identified by legislation defined above.
b. The Coastal Barrier Resources Act (CBRA) was passed by Congress in 1982 to encourage conservation of hurricane-prone, biologically rich coastal barriers. CBRA prohibits most new federal expenditures that encourage development or modification of coastal barriers. Therefore, most new or substantially improved residences, businesses, or other developments in the Coastal Barrier Resources System (CBRS) are not eligible for certain federal funding and financial assistance, including coverage under the National Flood Insurance Program (NFIP). Development can still occur within the CBRS, as long as private developers or other non–federal parties bear the full cost.
CBRS boundaries are shown on maps that were originally adopted by Congress, and with few exceptions, only Congress can change the CBRS boundaries. The official CBRS maps are maintained by the U.S. Fish and Wildlife Service (USFWS).
