Abstract: The San Diego Association of Governments (SANDAG) is proposing the San Diego Regional Beach Sand Project to replenish the County's beaches. SANDAG represents the Cities within San Diego County. SANDAG received $9.6 million from the U.S. Navy and $3.7 million from the State Department of Boating and Waterways for $14.3 million total to implement a project. The funding was initially to be used by the Navy to nourish beaches with sand dredged for a carrier project, but the project was halted after munitions were found in the sand. The funds were subsequently reallocated to the regional project. The project is replenishing 13 San Diego County beaches with 3 million cubic yards of sand. The project was proactively designed to avoid causing significant environmental impacts and to minimize mitigation requirements. The replenishment sites are located within each City from Oceanside to Imperial Beach. Sand is proposed to be dredged from 7 offshore borrow sites also located between Oceanside and Imperial Beach using large capacity dredging equipment. The dredging and beach fill quantities, pumping distances, and dimensions of each beach fill site have been determined and will be presented. SANDAG has prepared preliminary design after completing the tasks of investigating potential sand sources, assessing beach replenishment sites for their capability to receive sand considering environmental constraints and other factors, researching material transport options and considering retention strategies. Preliminary plans for dredging and beach replenishment are presently the subject of environmental review and permitting. The project schedule envisions sand to be placed on the beach in the Spring of 2000.
