Sand and gravel are primary resources used in many phases of construction and to maintain southern California's valuable beaches and harbors. Deposits of saleable-grade material under present political and economic conditions are becoming depleted. Although many land-based deposits are lost to competing land uses and mining of such deposits is generally opposed by urban communities, offshore,Monitoring of sand and gravel extraction at sea | FPS,Offshore sand and gravel extraction; Control Monitoring of sand and gravel extraction at sea.
