of 2,800,000 cubic yards of material dredged from Los Angeles Outer Harbor. 

 Adequate access and public park facilities have also been provided. The 

 artificial beach is in good condition, but is subject to rapid erosion. 



Los Angeles County has adopted a master plan of shore line development 

 for recreational purposes which includes, among other things, widening the 

 beaches from Topanga Canyon to Ballona Creek, a maximum of 1,200 feet and 

 from El Segundo to Malaga Cove to widths of 300 to U50 feet. The plan 

 proposed groin systems to stabilize the widened beaches and also a groin at 

 Cabrillo Beach to stabilize the beach already widened at that location. 

 Other incidental work included in the plan comprised extension of existing 

 storm drains and removal of the Santa Monica Breakwater. Navigation improve- 

 ments at Playa del Rey and Redondo Beach Harbor, also included in the master 

 plan, were considered by the Corps of Engineers in previous reports and so 

 were omitted from the present report except for necessary overlapping 

 details o 



The district engineer with concurrence of the division engineer and 

 Beach Erosion Board developed a modified plan for protecting the shores of 

 Los Angeles County. They concluded that since the shore to be improved 

 was or will be publicly owned and public interest in the improvements is 

 100 percent, Federal participation to the extent of one-third of the total 

 cost of the protective features, in accordance with the policy established 

 by Public Law 727, 79th Congress, is t^arranted. They recommended adoption 

 of a Federal project for reimbursement subject to certain conditions, to 

 local interests of an amount equivalent to one-third of the cost of the 

 protective features of the following modified master plan of shore line 

 development: widen the existing beaches to approximately 1,000 feet between 

 Topanga Canyon and Ballona Creek (seaward 200 feet considered a protective 

 feature), and to approximately 300 feet between El Segundo and Malaga 

 Cove (seaward 150 feet considered a protective feature), except between the 

 Redondo Beach breakwater and a barrier groin to be constructed near Topaz 

 Street in Redondo Beach; construct nine groins between Topanga Canyon and 

 Ternescal Canyon; construct five groins between Temescal Canyon and the 

 proposed entrance to Playa del Rey Harbor (to be deferred pending demonstra- 

 tion of need) | extend seven storm-drain structures through the widened beach 

 (that part extending through the protective beach considered a protective 

 feature); acquire and rehabilitate the Santa Monica breakwater; construct 

 a barrier groin in the vicinity of Topaz Street in Redondo Beach (to be 

 deferred pending demonstration of need);: and construct a barrier groin 

 at Cabrillo Beach; all at an estimated total first cost of 4<9,U88,000 for 

 the protective features, of which the Federal Government would reimburse 

 local interests in an amount estimated at ^3,103,000. 



In accordance with existing staturory requirements, the Beach Erosion 

 Board stated its opinion that: 



a. It is advisable for the United States to adopt a project 

 authorizing Federal participation in the cost of protecting the proposed
