Power for operating the pumps would be provided by the generating 

 stations of the Narragansett Electric Company, to be protected by the 

 barrier. Two stations having a total generating capacity of 3c30,000 

 kilowatts are located within 2,000 feet of the pumping station. Electric 

 power, supplied by direct underground service, would be available from 

 either or both stations. These stations are tied in to the main trans- 

 mission line of the New England Electric System which withstood the high 

 winds of past hurricanes. Considering the reliability of these services 

 of electric power no provision has been made for standby power or diesel 

 pumps. 



f . Foundations . Due to the poor foundation conditions piles were 

 considered essential. Steel "H" piles were selected due to ease of 

 handling, splicing and driving. Steel sheet piling was provided as 

 forms for the tremie concrete cofferdam and as a seepage cutoff. 



g. Land walls . The land walls were designed for a water loading 

 to the top of the wall on the seaward side. 



F-10. MODIFICATIONS TO SEWERS AND DRAINAGE 



Gates would be provided on sewers and drains which pass under the 

 land walls. During a hurricane the gates would be closed and the 

 flow diverted. 



F-11. LANDS AInID DAMAGES 



No major street or highway relocations would be caused by the 

 construction of the Fox Point barrier. The structures, where they do 

 not adjoin streets, would require strips of land for construction and 

 maintenance. Where they do adjoin streets, some highway modifications 

 would be required, but they would not obstruct traffic. 



The existing waterway above the barrier presently services the 

 Narragansett Electric Company, the Block Island Ferry and others. The 

 use of the waterway must be discontinued and other facilities 

 substituted. 



F-12. PLAN OF CONSTRUCTION 



During the first construction season the foundation of the 

 cooling water intake structure would be installed and the pumping 

 station cofferdam would be placed. Piles would be driven for the 

 pimping station, the foundation mat poured, and the substructure, 

 including pump housings, draft tubes, and trash racks, would then 

 be constructed. The cofferdam would be removed, and foundation and 

 substructure for the sluice gates and barrier proper would be 

 completed.
