the South Atlantic, Gulf, and Pacific regions. Examples 

 of this shift in population concentration are found in the 

 Central Calif. Coast, which 1s expected to grow from a 

 population density of a little more than 350 persons per 

 square mile 1n 1970 to nearly 600 in 2000, and 1n the Tex. 

 North Gulf Coast which will experience a population density 

 growth from 225 persons per square mile 1n 1970 to over 

 400 per square mile 1n that same thirty year period; 



(4) Although some areas in the United States will remain 

 relatively lightly populated, the pressures of Increased 

 population will be felt 1n even the most remote coastal 

 areas, 1f not by local population growth, then by increa- 

 sing demands of more urbanized populations for the ameni- 

 ties of the coastal zone; often expressed 1n terms of 

 seasonal influxes; 



(5) The effects of Increased population density will vary 

 according to a number of considerations such as the 

 employment structure, distribution of the population within 

 the area, the biophysical environment, institutional 

 constraints, and so on; 



(6) Finally, many of the conflicts generated by competing 

 demands on the estuarine resource, which are most visible 

 1n today's metropolitan areas, will intensify in those 

 areas in the future and extend to estuarine areas which
