Los Angeles County Department of Beaches and Harbors

The Los Angeles County Department of Beaches and Harbors is responsible for 20 beaches and the Marina Del Rey small-craft harbor in Los Angeles County, California.

Marina
The department also manages the Marina Del Rey small-craft harbor, which has “4,600 boat slips in 23 marinas” and brings in nearly $60 million annually in revenue. The Marina function was added by the Board of Supervisors in 1954. The department also operates Burton Chace Park, and monitors raptor and waterbird nesting sites in Marina Del Rey's urban forest; tree trimmers wishing to work in the area must apply for a special permit.

Beaches
Management of the beaches was shifted from the Parks and Recreation department in May 1969. L.A. native Dick Fitzgerald was the first director of the Department of Beaches. In 1976, Fitzgerald advocated for marine reserves to protect the tide pool ecosystems at Abalone Cove and Vista Sudeste. Circa 1975, when the city of Los Angeles handed over management of the “lifeguards, maintenance, parking and concessions” at their beaches to the county, the department oversaw 73 mi of the 76.5 mi of beaches in the county, including 38 mi miles of “improved beaches.”

“The beaches surrounding Santa Monica Bay were visited by more than 42.5 million people in 1987,” according to the department's Lifeguard Division. The Los Angeles County Lifeguards were transferred to the Los Angeles County Fire Department in 1994.

The following beaches are owned or operated by the department, sometimes in partnership with the State of California or a city government: Beaches and Harbors also runs the Dockweiler Beach RV parking and campground facilities, as well as Dockweiler Youth Center.
