The Lower Bay barriers would require one or more new quarries 

 and rights-of-waty to the water for barging or to the site for end 

 duI^^)ing, At the west end of the West barrier, a number of small 

 beach houses would require relocation. The east end of the East 

 barrier would tie into higher groiind at one of the large estates 

 in Newport. At the Conanicut Island ends of both barriers, and 

 for the land wall on the island, lands and rights-of-way woTjld 

 be required. 



The Tiverton barrier would require shorefront easements, rights- 

 of-way and a few relocations. It is easily accessible from both 

 ends. 



60. OPERATION AND MAINTENANCE 



a. Fox Point barrier . The Fox Point barrier would ordinarily 

 require no operation and the sluice gates would be left open for 

 river flow and tidal flushing. Diiring the hurricane season, however, 

 maintenance personnel would stand by. The sluice gates and cooling 

 water intake gate could be closed very quickly, hence, their closure 

 would not be necessary until a relatively late stage of the hurricane 

 warning, but preferably at a low tide. Upon the close approach of 



a hurricane, the gates would be closed, and the fresh water pool 

 kept low by punping. 



Maintenance of the pumps and motors within the piai5)ing station 

 would necessitate periodic testing, involving running all motors 

 and pumps for a short time and checking performance. 



b. Lower Bay barriers . The East and West barriers as presently 

 considered would reqviire no operation. Maintenance would be limited 

 to replacing stone dislodged by wave action, aiid maintaining the 

 quarry as a source of rock fill. 



The Tiverton barrier would require operation of the sector 

 gates. These gates would be closed before the hurricane danger 

 became acute, and would be left closed until the danger had passed. 

 Therefore, periodic testing of the gates am operating machinery 

 and ordinary maintenance of enibankraent, concrete features, and 

 equipment would constitute the chief operation requirements. 



61. HIGHWAY CROSSINGS UTILIZING BARRIERS 



a. Fox Point barrier . The design of the Fox Point barrier 

 is adaptable to possible fut xire use as a highway crossing, and 

 access to and across it is a feature of the present plans.
