(3) Conimlcut Point barrier * This site was studied and 

 a barrier made iif of rock fill, a large puitqping station (30,000 

 c.f.s.) and a UOO-foot gated navigational opening was considered. 

 This site was mled out by the high cost of punping and buildi?) 

 below the barrier. 



(U) Middle Bay barrier . This site was studied and rock- 

 fill barriers closing off the East and West Passages wsre considered. 

 This barrier would require navigation openings for both passages. 

 This site was ruled out due to excessive buildi^) below the barrier. 



(5) Sakonnet River barriers . In addition to the selected 

 Tiverton barrier, other sites at Black Point, Sandy Point, McCurry 

 Point, and the Hummocks were studied. These were more costly than 

 the plan selected, without commensurate increase in benefit.
