Public Law 115-358

New maps depicting 59 units of the CBRS in Delaware, Florida, North Carolina, and South Carolina were made effective on December 21, 2018 via the Strengthening Coastal Communities Act of 2018 (Pub. L. 115-358). These maps comprise about seven percent of the total CBRS units and constitute the largest legislative update to the CBRS since 1990.

Public Law 115-358 helps to preserve the long-term integrity of the CBRS by adopting maps prepared by the Service through a comprehensive process to correct legitimate mapping errors and add qualifying areas to the CBRS. This effort also provides more accurate CBRS maps and digital data for planning coastal infrastructure projects, habitat conservation efforts, and flood risk mitigation measures.

Thirty-two of these maps were produced through the Service’s Digital Mapping Pilot Project. Three of these maps for CBRS units in Bay County, Florida were produced through the technical corrections process.
