The Santa Monica Bay Watersheds include the North Santa Monica Bay, South Santa
Monica Bay, and Marina Del Rey Watersheds. The North Santa Monica Bay
includes the Malibu Creek Watershed, Topanga Creek Watershed, and other rural
Santa Monica Mountains Watersheds. The South Santa Monica Bay
watersheds span from the Castlerock Watershed near Malibu to Palos Verdes
Peninsula Watersheds on the south. The Marina Del Rey watershed
encompasses all areas that drain to the marina. Portions of these watersheds
are very rural and undeveloped, and other portions are very urbanized. These
watersheds include all or parts of the Cities of Westlake Village, Agoura
Hills, Calabasas, Hidden Hills, Malibu, Los Angeles, Santa Monica, Culver City,
El Segundo, Manhattan Beach, Hermosa Beach, Redondo Beach, Torrance, Palos
Verdes Estates, Rolling Hills Estates, Rolling Hills, and unincorporated Los

the water quality in the bay while still providing adequate flood protection.
