Fox Point would give the highest ratio of hurricane protection 

 for expended money of any single site in the bay. It wo\ild 

 completely protect downtown Providence, including the South 

 Street ard Manchester Street steam-electric plants of the 

 Narragansett Electric Company. 



b. Lower Bay barriers . The most practicable sites in the 

 Lower Bay are in the three narrow entrances to the Bay. For a 

 closure of the East Passage at the mouth of the Bay there is 

 little choice among alternative sites, since the narrowest reach, 

 off Bull Point opposite Newport, is only about one mile long. 

 In this reach, deep waters, up to l65 feet deep, cannot be 

 avoided. The site selected for the East barrier after careful 

 study is about 2,500 feet southvjest of the 5ii-degree turn in 

 the navitration channel of Bull Point. This, more than any other 

 alternative site, would facilitate passage of Naval and commercial 

 vessels . 



After study of five alternative barrier sites in the west 

 Passage in a 3-niile reach extending from the Jamestown Bridge 

 south to Bonnet Shores, a site about 600 feet souta of the 

 Jamestown Bridge v:as selected. Although barriers farther south 

 in the vvest Passage would protect a larger area, the Jamestovm 

 Bridge site was chosen to take advantage of better foundation 

 conditions, with consequent need for smaller quantities of 

 rock in construction, and to combine the opening in the barrier 

 with the 600-foot navigatio'al opening in the existing bridge 

 span. 



In similar fashion, various sites vjere considered to close 

 off the nead of the Sakonnet Kiver. A site at the existing stone 

 bridge at Tiverton, connecting Tiverton and the island Park 

 area in Portsmouth, was selected as providin'j protection to 

 the greatest part of developed property in the immediate area, 

 at the minimum construction cost.
