What makes East Lakewood different?
When Lakewood bought the private Lakewood Water and Power Company and two smaller water providers in 1957–59, the city's utility took over service west of the river. Residents east of the San Gabriel River continue to be served by the privately owned Golden State Water Company, according to A city of neighborhoods. The same history notes that Bloomfield Park, a 15-acre park, began as a county facility in the unincorporated neighborhoods east of the river and became part of Lakewood when the city annexed the area. In the late 1970s, a city committee put federal funds into sidewalks and tree planting in eastern Lakewood.

Landmarks on the east bank
Rynerson Park, dedicated in 1990 and named for former mayor Jacqueline Rynerson, runs along the east bank of the river. It includes the 19-acre Lakewood Equestrian Center, which started as the Spiller Stables, and the Home Run Dog Park at its northern end. Lakewood Little League fields sit next to the park, on land leased from Southern California Edison under the power lines since 1969.

Housing east of the river is mostly post-war single-family homes, with the same slab foundations, aging supply lines and older sewer laterals as the rest of Lakewood. The big practical difference is the water provider. For a leak at the meter, a billing question or a water quality concern, contact Golden State Water. For anything on the house side of the meter, you need a plumber.
Who supplies water in East Lakewood and Imperial Estates?
Homes in East Lakewood and Imperial Estates get water from the Golden State Water Company.
