This legislation directs the Secretary of the Interior to amend the official maps of the John H. Chafee Coastal Barrier Resources System (CBRS). Specifically, it targets Unit L06 within North Topsail Beach, North Carolina, requiring boundary corrections within 30 days of enactment. The bill aims to adjust the system's coverage based on existing local land-use designations. The primary purpose of these corrections is to exclude from Unit L06 any parcels located in North Topsail Beach that, as of the bill's enactment, are designated by local zoning ordinances for purposes other than conservation . This ensures that areas already zoned for development or other non-conservation uses are removed from the federal CBRS designation, which typically restricts federal expenditures and financial assistance for development. The bill clarifies that this applies only to areas within the municipality of North Topsail Beach and that the excluded parcels will be considered to meet specific criteria under the Coastal Barrier Resources Act.
