The Coastal Barrier Resources Act (CBRA) requires the Secretary of the Interior to review the maps of the (CBRS) at least once every 5 years and make such minor and technical modifications necessary to reflect changes in the size or location of the CBRS units as a result of natural forces (16 U.S.C. 3503(c)).
The U.S. Fish and Wildlife Service (Service) conducted the 5-year review in 2023 for the following areas: all the CBRS units in Georgia and Maine, the 21 units in the Great Lakes region of New York, and certain units in Florida and Louisiana. A stakeholder review period for Federal, State, and local officials is open through December 4, 2023. The Federal Register Notice of Availability (88 FR 75621) contains summaries of the proposed modifications for individual CBRS units and instructions for providing comments on regulations.gov or by mail or hand-delivery. The draft boundaries may be viewed using the CBRS 5-Year Review Web Mapping Application, A shapefile of the draft boundaries is also available below.
Please note that through this project, we consider changes to the maps that are consistent with our administrative authority to modify the CBRS boundaries, which is limited to: (1) changes that have occurred as a result of natural forces such as erosion and accretion; (2) voluntary additions to the CBRS by property owners; and (3) additions of excess federal property to the CBRS (16 U.S.C. 3503(c)-(e)). Other types of changes to the CBRS boundaries are generally not considered under this project. Additional information regarding methodology can be found in the Federal Register notices linked above.
