Potential Sand and Gravel Resources in Santa Monica and San Pedro Bays: Southern California

Sand and gravel are primary resources used in many phases of construction and to maintain southern California´s invaluable beaches and harbors. Deposits of saleable-grade material under present political and economic conditions are rapidly becoming depleted. Many land-based deposits are lost to competing land use, and mining of such deposits is generally opposed by urban communities. Offshore sand and gravel deposits in Santa Monica and San Pedro Bays offer a possible alternative to mining land-based deposits for beach nourishment and construction materials.
