Coastal zone.

Coastal zone. Coastal zone has the same meaning that the term has in section 
304(1) of the Coastal Zone Management Act of 1992 (16 U.S.C. 1453(1)). The 
coastal zone consists of coastal waters (including the lands therein and 
thereunder) and the adjacent shorelands, including islands, transitional and 
intertidal areas, salt marshes, wetlands, and beaches. The zone extends, in 
Great Lakes waters, to the international boundary between the United States and 
Canada and, in other areas, seaward to the outer limit of the United States 
territorial sea. The zone extends inland from the shorelines only to the extent 
necessary to control shorelands and protect coastal waters.
