The maps referenced on this page are comprehensively revised draft maps prepared by the U.S. Fish and Wildlife Service (Service) for public review (referred to as “proposed maps”) or Congressional consideration (referred to as “final recommended maps”). These draft maps make progress toward fulfilling a mandate in the Coastal Barrier Resources Reauthorization Act (Pub. L. 109-226) to modernize all John H. Chafee Coastal Barrier Resources System John H. Chafee Coastal Barrier Resources System

Florida

The Service has transmitted to Congress comprehensively revised final recommended maps for two CBRS units (Moreno Point Unit P32/P32P) located in Okaloosa and Walton Counties, Florida. This project makes progress toward fulfilling the statutory requirement to modernize the entire set of CBRS maps (Pub. L. 109-226). The revised CBRS boundaries (including recommended removals and recommended additions) will only become effective once the revised maps are adopted into law by Congress.

The final recommended maps for these CBRS units, dated April 29, 2021, were prepared following a 60-day public review period for the proposed boundaries that ended on March 5, 2021. The final recommended maps, summary of the public comments received and the Service's responses to those comments, and summaries of the final recommended changes to the units are below. An archive of the earlier proposed boundaries and associated documents is also available below.

South Carolina

The Service has transmitted to Congress comprehensively revised final recommended maps for six CBRS units (Morris Island Complex M06/M06P, Harbor Island Unit M11, St. Phillips Unit M12/M12P, and Hunting Island Unit SC-09P) located in Beaufort and Charleston Counties, South Carolina. This project makes progress toward fulfilling the statutory requirement to modernize the entire set of CBRS maps (Pub. L. 109-226). The revised CBRS boundaries (including recommended removals and recommended additions) will only become effective once the revised maps are adopted into law by Congress.

The final recommended maps for these CBRS units, dated April 29, 2021, were prepared following a 60-day public review period for the proposed boundaries that ended on March 5, 2021.

Minor and Technical Corrections in North Carolina and Florida

The Service has transmitted to Congress minor and technical correction maps for one unit (Grayton Beach Unit FL-95P) located in Walton County, Florida, and one unit (Topsail Unit L06) located in Onslow County, North Carolina. The minor and technical correction maps for these two units address errors on maps that were previously modernized and adopted by Congress in 2006 and 2018 respectively. These two corrections would remove from the CBRS small areas (less than four acres total containing three structures) in order to correct technical mapping errors resulting from the limitations of Geographic Information Systems data (including parcels and aerial imagery) available in the early 2000s when the mapping work was done for these units. The Service has prepared revised maps to reflect these minor and technical corrections, and has determined that no other changes are needed to these maps.

The minor and technical correction maps and summaries of the minor and technical correction changes to the units are below.
