Research, Resilience and risk mitigation

The U.S. Fish and Wildlife Service (Service) has prepared draft revised boundaries for 23 existing Coastal Barrier Resources System (CBRS) units and 6 proposed new units (a total of 29 units) in Miami-Dade and Monroe Counties, Florida. This project makes progress towards fulfilling a statutory requirement (section 4 of Public Law 109-226) to modernize the maps and make recommendations to Congress for additions to the CBRS. If adopted by Congress, the revised maps would both remove areas that were included in error and add qualifying areas to the CBRS. More detailed information regarding the specific proposed changes to each unit is available in the summaries of proposed changes below.  

We invite the public to review the draft revised boundaries and provide input to the Service during the 120-day public comment period that will close on July 12, 2024. Comments may be submitted at Regulations.gov (search for FWS-HQ-ES-2023-0205) or by mail or hand-delivery as described in the Federal Register notice.

Following the close of the public comment period, the Service will make any appropriate changes based on public comments, CBRA criteria, and objective mapping protocols. We will also prepare summaries of and responses to the comments received along with final recommended maps for Congressional consideration. The revised CBRS boundaries (including recommended removals and recommended additions) will only become effective once the revised maps are adopted into law by Congress.
