Relationship of Internal Waters, the Territorial Sea, the Contiguous Zone, and the 

 Continental Shelf 



is g^iven permanent, exclusive access as in- 

 cluding "the mineral and other nonliving 

 resources of the seabed and subsoil together 

 with living organisms * * * which, at the 

 harvestable stage either are immobile on or 

 under the seabed or are unable to move ex- 

 cept in constant physical contact with the sea- 

 bed or subsoil." 



Geographic Scope of the Coastal Zone 

 and Division of Authority in the Zone 



In discussing the problems of the coastal 

 zone, the Commission has avoided precise def- 

 initions, but for purposes of the proposed 

 coastal management system, the Commission 

 inews the coastal zone as including (1) sea- 

 ward, the territorial sea of the Ignited States 

 and (2) landward, the tidal waters on the 

 landward side of the low water mark along 



the coast, the Great Lakes, port and harbor 

 facilities, marine recreational areas, and in- 

 dustrial and commercial sites dependent upon 

 the seas or the Great Lakes. Each coastal 

 State, however, should be authorized to define 

 the landward extent of its coastal zone for 

 itself. 



Subject to the constitutional powers of the 

 Congress (principally in this case, the power 

 to regulate interstate and foreign commerce, 

 including navigation) , the States have prime 

 responsibility and authority for managing 

 the landward areas of the coastal zone. Sea- 

 ward, the situation is more complicated. By 

 virtue of the Submerged Lands Act of 1953, 

 the coastal States, except for Texas and Flor- 

 ida, own the living and nonliving resources 

 of the seabed and subsoil of the sea out to 3 

 nautical miles from their coastlines. Texas
