Stormwater Management

Stormwater Management Program

Stormwater runoff is a significant source of pollutants to the Bay. Pollutants such as trash, litter, sand, sediment, petroleum products leaking from motor vehicles, heavy metals in the dust from motor vehicle brake pads and diesel exhaust, animal feces, excess fertilizers and pesticides, and others are carried to the Bay by urban runoff as a result of rain or excessive irrigation, or other sources of water in the urban environment. The major inputs of stormwater to San Diego Bay include the Sweetwater River, Otay River, Switzer Creek, Chollas Creek, Paradise Creek, and all the surface runoff from downtown San Diego and other urbanized areas discharged through approximately 200 storm drain outlets.
