Digital CBRS Boundaries
The U.S. Fish and Wildlife Service (Service) has geospatial Coastal Barrier Resources System (CBRS) polygon data available in a variety of formats. The CBRS polygons are only representations of the official CBRS boundaries and are not to be considered authoritative. In general, these digital boundaries can be considered accurate to within approximately 20 feet of the actual CBRS boundaries as shown on the official maps. For information on the horizontal accuracy of this digital data set, please read the metadata and see the "CBRS Buffer Zone" layer.
Additionally, because CBRS units extend seaward out to either the 20- or 30-foot bathymetric contour (depending on the location of the unit), the true seaward extent of the units is not shown. The Service is not responsible for any misuse or misinterpretation of this digital data set, including use of the data to determine eligibility for federal financial assistance such as federal flood insurance. For information on obtaining an official determination of whether or not an area or specific property is located within the CBRS, please visit: www.fws.gov/ecological-services/habitat-conservation/cbra/Determinations.html. For information on project consultations, please visit: www.fws.gov/ecological-services/habitat-conservation/cbra/Consultations/Consultations.html.
Attention FEMA Mapping Partners: Do not use these data for Flood Insurance Rate Maps (FIRMs). Please follow FEMA's Guidance for Flood Risk Analysis and Mapping: Coastal Barrier Resources System Mapping on Flood Insurance Rate Maps and contact cbra@fws.gov> to obtain the appropriate data for the FIRMs.
