Updated Digital Maps Show Changes to  


Coastal Barrier Resources System in Five States  

Final revised maps for all John H. Chafee Coastal Barrier Resources System units in Delaware, South Carolina (including one unit that crosses the state boundary into North Carolina) and Texas, and one unit in Florida are now available from the U.S. Fish and Wildlife Service. The revised maps are accessible via an online mapper at The Coastal Barrier Resources Act requires the Secretary of the Interior to review and edit the maps at least once every five years to reflect changes in coastal barriers from natural forces.

The updated maps were produced through a digital conversion project in partnership with the Federal Emergency Management Agency. The Service plans to complete digitally converted maps for units in Maine, Maryland, New Jersey, New York City, North Carolina and Virginia by the end of this year. Updated maps for the entire System are scheduled to be completed by the end of 2016.

The Coastal Barrier Resources System was established in 1982. It comprises a total of 856 geographic units that encompass approximately 3.2 million acres of relatively undeveloped coastal barrier lands located along the Atlantic, Gulf of Mexico and Great Lakes coasts, as well as Puerto Rico and the U.S. Virgin Islands. Most new federal expenditures and financial assistance that encourage development are prohibited within the System, including federal flood insurance. However, development still can occur within the System, provided that private developers or other non-federal parties bear the full cost, rather than the American taxpayers.
