The Marsh development study was initiated to formulate workable procedures for the artificial propagation of intertidal marsh land plants upon a dredge material substrate. on the intertidal margins of San Francisco Bay are two dominant marshland plants: California cordgrass (Spartina foliosa) and, pickleweed, consisting of several representatives of the Genus Salicornia. A survey was made of potential marshland development areas in San Francisco Bay in conjunction with the study. The survey indicated that there were approximately 270 sq km of diked lands adjacent to San Francisco Bay which could be filled to provide elevations appropriate for marsh development. The depth of fill to achieve desired elevations would seldom exceed two meters and would typically be from 0.5 to 1.0 meters in these areas. Theoretically, therefore, 200 to 250 million cu m of dredged material could be accommodated if total utilization was made of the marsh development disposal alternative.
