This report discusses the development of a stretch of beach along 

 the shore of the Santa Monica Bay by artificial widening. The report 

 takes into consideration the source of the sand on these beaches, the 

 movement of sand along the beaches, the effects of the ocean waves and 

 currents, the tides, natural and artificial obstructions along the shore, 

 and rainfall, erosion and flood conditions in the tributary watersheds. 

 Much of the data on waves, currents, tides, winds, sand movement, and 

 rainfall and flood conditions in the tributary watersheds, contained in 

 the April 1940 report on Venice Beach, are pertinent to this report, and 

 are repeated herein with the necessary modifications.

This article discusses new shore structures and further erosion, 

 emphasizing the necessity for proper planning, and the preservation and 

 development of shorefronts in the interests of an entire area, not just 

 one locality.

The most difficult problem in shoreline planning is that of beach 

 erosion, largely caused by haphazard and ill-advised developments by 

 local coastal communities. Control of pollution by oil and sewage is 

 also troublesome. The need for a greater extent of publicly owned ocean 

 frontage has been recognized for years, and is largely a matter of financ- 

 ing. Development and improvement of public ocean frontage is also largely 

 a matter of financing, plus proper planning. This article presents a 

 brief outline of most of these problems.

In the May 1940 issue of Western City, an article by this writer 

 entitled "The Vanishing Beaches of Southern California" described the 

 serious beach erosion which had been caused by construction of break- 

 waters and jetties along the southern California coastline, particularly 

 at Santa Barbara, Santa Monica, Venice, Redondo Beach, and Long Beach.
