highway and adjacent property from high tides and storm wave action 

 and to provide a more suitable recreational beach. 



The division engineer considered the desires of the cooperating 

 agency , studied the existing structures, the sources and movement of 

 beach material, the changes in the shore line and offshore bottom, 

 the effects of winds and storms, developed plans for protecting and 

 improving the shore of the study area, and made an economic analysis 

 of proposed new protective and improvement construction for djuincy 

 Shore Beach. He found that prospective benefits warrant construction 

 of these measures and that the public interest therein justifies 

 Federal participation to the extent of one-third of the total cost 

 of the recommended new work, in accordance with the policy established 

 by Public Law 727, 79th Congress. 



The division engineer recommended, subject to certain conditions, 

 adoption of a project authorizing Federal participation in an amount 

 equal to one-third of the first cost of protecting and improving the 

 shore of the Metropolitan District Commission Quihcy Shore Reserva- 

 tion, Massachusetts, by; 



a. Placing approximately 126,000 cubic yards of sand and 

 gravel, and 221,500 cubic yards of sand on the beach between Hovey 

 Street, and Rufe's Hummock Sea Wall, a distance of 8500 feet, to 

 provide a backshore elevation of 15.0 feet above mean low water j 



b. Constructing a concrete-encased steel sheet-pile 

 bulkhead with a top elevation of 18 feet above mean low water 

 between the parapet wall, near Hollis Avenue, and the National 

 Sailor's Home Hill Sea Wall, a distance of 4750 feet; 



c D Constructing a concrete sea wall, with a top elevation 

 of 19 o2 feet above mean low water, in extension of the existing 

 parapet wall to high ground at Billings Street, a distance of 325 

 feet | 



do Constructing two impermeable stone groins each 350 

 feet long, with tops generally 2 feet above the highest adjacent 

 fill, one 200 feet north of the Squantum Yacht Club, the other 200 

 feet south of the Wollaston Yacht Club; and 



e. Constructing a culvert at Sachem Creek, and extending 

 existing drains across the beach to discharge seaward of the recommend- 

 ed fill. 



The Beach Erosion Board carefully considered the report of the 

 division engineer and concurred generally in his conclusions and 

 recommendations, subject to the following comments.
