Reclamation of Bay wetlands and disposal of dredge spoils: meeting two goals simultaneously

San Francisco Bay is one of the world's largest urbanized estuarine systems with a watershed that drains about 40 percent of the State of California. Its freshwater and saltwater marshes comprise approximately 125 square kilometers (48 square miles), compared to 2,200 square kilometers (850 square miles) before California began rapid development in 1850. This staggering reduction in tidal wetlands of approximately 95 percent has resulted in significant loss . of habitat for many species of fish and wildlife. The need for wetlands is well documented- healthy and adequate wetlands are critical to the proper functioning of an estuarine ecosystem like San Francisco Bay.
