Digital CBRS Boundaries

Coastal Barrier Resources System (CBRS) polygons in this data set 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 150 feet of the actual CBRS boundaries as shown on the official maps.  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 shownThe 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: http://www.fws.gov/cbra/Determinations.html.  For information on project consultations, please visit: http://www.fws.gov/CBRA/Consultations/Consultations.html. For information on the horizontal accuracy of this digital data set, please read the metadata.

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.
