The study area is characterized by headlands of unconsolidated glacial 

 material with some rock outcrops , between which wave-built bars have been 

 formed and the landward areas generally have filled and become marshy. The 

 Connecticut River transports and deposituS material in Long Island Sound, 

 some of which probably reaches either the beaches or offshore bottom in the 

 western portion of the study areao The headlands formerly supplied ample 

 material to the intervening beaches^ but the headlands are now generally 

 protected by seawalls and revetmentso The supply of material has thus been 

 reduced or eliminated, and consequently the beaches have slowly deteriorated. 

 Groins have been found to be capable of causing minor accretion areas and 

 stabilizing a narrow band along the upper portion of the beach., but the 

 natural supply of material is insufficient for the formation of adequate 

 protective beaches by groins alone,, The building and maintenance of adequate 

 beaches may be accomplished by artificial placement of sand. The rate of loss 

 of fill can be reduced by groins o 



The Division Engineer and the Beach Erosion Board concluded that the 

 best plans for the protection and improvement of beaches within the study 

 area vjere as follows; 



a, Giants Meek - Direct placement of sand fill along the west 

 bank of the Pataguanset River. 



bo White Sand Beach - Direct placement of sand fill along the 

 easterly IjUOO feet of this beach and construction of an impermeable groin 

 at the west limit of the fill., 



They also found that the proposed project for White Sand Beach is 

 justified by evaluated benefits, but that the limited public interest 

 other than recreational involved in the improvement, and the minor Federal 

 aid for which the project would be qualified did not warrant adoption of a 

 Federal project for protection of this areao They recommended that local 

 interests consider adoption of a project for the protection and improvement 

 of this beach^ in accordance with the plan outlined in the preceding para- 

 graph. The shore at Giants Neck is privately owned and thus not eligible 

 for Federal assistance in the cost of protective measures. 



In accordance with exj.sting statutory requirements the Board stated 

 its opinion that; 



a. It is inadvisable for the United States to a dopt projects 

 authorizing Federal participation in the cost of protecting and improving 

 the shores within the area studied; 



b. The public interest involved in the proposed improvements 

 for these shores is small and primarily local; and 



c. No share of the expense should be borne by the United States. 



The Chief of Engineers concurred with the recommendations of the Beach 

 Erosion Board.
