the CBRS conducted by the Service that modifies boundaries only to reflect changes due to natural processes such as accretion and erosion. Since the establishment of the CBRS in 1982, several pieces of legislation have removed land from the CBRS, making it available to federal subsidies for development. Congress determined the initial CBRS units in 1982, and modified and expanded the CBRS in 1990. Subsequent modifications to the CBRS have since been made via Congressional action. If a technical mapping error warranting a change in any single part of the CBRS map is found by the Service, all adjacent areas must be reviewed to ensure the map’s accuracy. This is a comprehensive approach to map revisions that treats all landowners who may be affected equitably, and ensures that Congress will not have to remap the same area in the future. While this may be an extensive process, it allows the Service to uphold the integrity of the entire CBRS by looking at boundary revisions in a holistic manner instead of pursuing incremental fixes for individual areas on a single map. Map modernization On April 7, 2009, the U.S. Fish and Wildlife Service (Service) released to the public its Report to Congress: John H. Chafee Coastal Barrier Resources System Digital Mapping Pilot Project and announced the start of a 90-day public comment period. The report, which was directed by the Coastal Barrier Resources Reauthorization Act of 2000 (P.L. 106-514), highlights the benefits of updating Coastal Barrier Resources System (CBRS) maps with more accurate and precise digital maps to better protect people, coastal areas and natural resources. The report includes draft revised maps for 70 units, or approximately 10 percent of the entire CBRS, and a framework for modernizing the remainder of the maps. The 70 pilot project units are located in Delaware, North Carolina, South Carolina, Florida and Louisiana. On June 29, 2009, the Service announced a 30-day extension of the public comment period. The public comment period closed on August 5, 2009. Accomplishments Since limiting federally subsidized development on designated coastal barriers, CBRA has managed to save federal dollars, protect humans by keeping them out of the path of deadly storm surges, and conserve valuable coastal habitat for fish and other wildlife. Since its enactment, CBRA has been promoted as a fiscally conservative, free-market approach to encourage coastal conservation. In no way does the Act regulate how individuals develop their
