Prolonged exploitation of coastal resources has caused extensive ecological harm. The alarming decline in the condition of the marine environment has become a matter of serious public concern. This Article will examine some of the environmental problems of the coastal zone and the resulting institutional responses. The first part will delineate a number of problems in the nation's coastal areas. The second part will review the doctrines of property law associated with the ownership of littoral land and their relation to land-use control measures. The third part will evaluate recent coastal management legislation. The fourth part will consider constitutional restraints on governmental action. Finally, the development of a sound public policy dealing with both the needs of the coastal environment and the difficulties of relating this policy to other societal goals will be discussed.
