 essential if a r^eaninoful permit review system is to be 

 instituted and maintained. Phvsical alterations of estuarine 

 and coastal zones bv dredoinq, fillino, bulkhead construction, 

 ditchino for mosouito control, and construction of new marsh 

 requires investioative work that would determine the effects on 

 water oualitv, the effects on biolooical life, and the effects 

 on hydraulics. Special attention should be paid in the development 

 of new harbors to retain or enhance the structual components 

 necessary for those oroanisns renuirinn Protected waters for

Fstuarine svstems will cnntiniie to receive heaw utilization for 

 all tvnes of nan's activities. Population trends indicate that 

 coastal areas are attractino a disproportionate nercentane of 

 our expandinn populations. Viith this trend we also have the 

 industrial activities necessary to support the economy. At the 

 present time, v;e can not predict accurately the assimilative 

 capacity of estuarine svstems, nor can we predict the Seoree 

 of deqradation ttiat will result from the enoineerino projects 

 proposed as necessary to proy^(^e the supportinn services for the 

 social and industrial structure.
