Coastal Zone Management Act Boundary

These data represent the extent of the nation's coastal zone, as defined by the individual states and territories under the Coastal Zone Management Act of 1972 (CZMA). The CZMA was established to preserve, protect, develop, and where possible, to restore or enhance the resources of the nation's coastal zone. The zone generally extends seaward to the boundary of the Submerged Lands Act. The zone extends inland from the shorelines only to the extent necessary to control shorelands that have a direct and significant impact on coastal waters. Lands held in trust by the Federal Government have been included in this boundary unless otherwise noted, as accurately representing these could be erroneous. State jurisdiction extends to 3nm, except for Texas, Puerto Rico and Florida's Gulf coast extends to 9nm. Great Lakes states have jurisdiction to the international boundary with Canada. CZMA applies in EEZ through federal consistency. This boundary is unofficial. For precise, regulatory boundaries, please contact the state or territorial coastal program office.
