(3) Fisheries and recreation. 



These problems, which must be resolved prior to construction, 

 will require additional investigation, extensive studies and 

 hydraulic model tests. 



i. One great flood would pay for the Fox Point project 

 cost several times over; a very real threat in the period of 

 years required for solution of the very difficult problems, 

 design, and construction of the Lower Bay barriers. 



RECOMMENDATIONS 



80. It is recommended that a two-xinit plan for hurricane 

 protection in Narragansett Bay be authorized for constrtoction 

 as follows: 



a. A barrier and accessories at Fox Point, as described in 

 paragr^h 57. The total estimated first cost of the Fox Point 

 barrier is ;iJl6, 500,000, to be borne jointly by the United States 

 and local interests. The estimated cost to the United States 

 would be $16,180,000. 



b. A series of Lower Bay barriers in the East Passage, 

 West Passage, and Sakonnet River as described in paragraph 58 ^ 

 subject to further studies of foundation conditions and satis- 

 factory resolution of the following problems: 



(1) Agreement with the Department of the Navy on 

 acceptable navigation openings. 



(2) Adverse effects on water quality and pollution 



in the Bay. 



(3) Adjustment of possible adverse effects on fish 

 and wildlife and recreation in the Bay. 



The total first cost of the Lower Bay barriers is estimated 

 to range between $69,000,000 and $109,000,000 depending on the 

 final design of the navigation openings, sluice gates, and founda- 

 tion. The first cost would be borne jointly by the United States 

 and local interests, with the cost to the United States ranging 

 between $67,273,000 and ^03, 203, 000.
