City of Boston, It comprises the southerly 6700 feet of the publicly 

 owned Quincy Shore Reservation which is under the jurisdiction of the 

 Metropolitan District Commission. The Reservation comprises a narrow 

 public beach which is generally under water at high tide, seawalls 

 and riprap shore protection, parking areas, and a boulevard. The 

 shore of the study area is lined with concrete seawalls except at the 

 southerly end where 4.00 feet of riprap have been placed. The beach 

 consists of coarse sand and gravel above mean tide level and mud 

 below that elevation. The offshore area is very flat and shoal, ex- 

 cept in the dredged yacht channel, and at low tide large calm flats 

 and other areas are exposed. 



The land immediately adjacent to the boulevard which traverses 

 the reservation is used for commercial purposes. The adjacent area 

 is a densely populated, urban, middle class residential area which 

 extends back across the City of Quincy, Two yacht clubs, the 

 Wollaston Yacht Club and the Squantum Yacht Club are located on 

 the bay sise of the reservation boulevard. Each club maintains a 

 pier which projects 350 feet into the bay to the head of a yacht 

 basin and channel which are maintained by the Commonwealth of 

 Massachusetts, 



Free public parking is provided along the entire length of the 

 beach on a parking strip between the highway and the seawall. Bus 

 service is provided within 800 feet of the beach by a system serving 

 the area south of Boston and connecting with the Metropolitan Transit 

 Authority system of Boston. The beach is open to the public free 

 of charge. There are no public bathhouses in the study area, but ex- 

 tensive use is made of the beach by bathers from nearby homes and 

 by those who travel to the beach attired in bathing suits. The daily 

 summer attendance is estimated to average 1000, Sunday and holiday 

 attendance 3000 to 5000. 



The existing beach in the study area was artificially developed 

 and resulted from the realignment of the shores of Quincy Bay by 

 construction in 1905 of a highway over beaches and marshes. The 

 highway was built on an embankment, the seaward face of which within 

 most of the length of the study area is now protected by a low 

 concrete stepped seawall which was constructed in 1926. The present 

 beach is the result of wave and tidal action on the highway embank- 

 ment. The stepped seawall is too low to provide adequate protection 

 to the highway and adjacent property and is, furthermore, presently 

 in need of extensive repairs. In 194-8 a reinforced concrete parapet 

 wall was added to the top of the northerly 1130 feet of the stepped 

 seawall. The parapet wall has since been extended about 1000 feet 

 in a southerly direction. 



In furtherance of the general purpose of the study, specific 

 problems at Quincy Shore Beach were found to require determination 

 of the most suitable measures to provide adequate protection to the
