69. UN EVALUATED TANGIBLE BENEFITS 



The planned protection of the Narragansett Bay area would 

 resTilt in additional important benefits which have not been 

 monetarily eval\:ated« Substantial benefits would stem from 

 the prevention of tangible damage to transient items such as 

 vessels afloat and vehicles parked on streets or in parking 

 lots. Benefits would also be realized from the reduction of 

 intangible losses^ including loss of life, health, and the 

 threat to national seciirity. Refer to Appendix D for a 

 detailed discussion of the derivation of annual losses and 

 benefits. 



70. INTANGIBLS BENEFITS 



Intangible benefits loom large in the total benefits to 

 be derived from the construction of proposed barriers. Loss 

 of life woiild be prevented. Dangers of disease arising from 

 polluted flood waters and water supplies would be eliminated. 

 Insecurity and worry among the residents concerning unpre- 

 dictable hurricane flooding causing loss of life and property 

 would no longer be a concern. Protection would stimiilate all 

 segments of the econoncr and improve the general welfare of the 

 residents. With vital Naval interests in the area, the plan 

 would significantly contribute to the national defense.
