Culver City Parks Task 8.1 Final Plan - Flipbook - Page 128
WATER
Existing System
When considering the existing conditions of water
management throughout Culver City, it is important
to identify potable water needs as well as overall
watershed health. The city’s water supply is provided
primarily by Golden State Water Company (GSWC)
and the city coordinates with GSWC on providing
water supply to serve park facility water demands.
In addition, water supply for Culver West Alexander
Park is provided partially by both GSWC and the Los
Angeles Department of Water and Power (LADWP).
Culver City is located within the Ballona Creek
watershed and the Marina Del Rey watershed. The
majority of Culver City, approximately 5.7 square
miles, is located within the urbanized Ballona
Creek watershed, which has a total drainage area
of approximately 130 square miles. The Ballona
Creek watershed is bounded by the Santa Monica
Mountains to the north, the Harbor Freeway on
the east, and Baldwin Hills on the south. Major
tributaries to Ballona Creek, a nine-mile-long flood
management channel, include Centinela Creek,
Sepulveda Canyon Channel, and the Benedict
Canyon Channel. The Culver West neighborhood,
a much smaller 42-acre portion of the city, is
located within the Marina Del Rey watershed, a
sub-watershed of the Santa Monica Bay watershed
and one of the smallest watersheds in Los Angeles
County at 2.9 square miles. The watershed primarily
drains to the Marina del Rey Harbor via the
municipal separate storm sewer system (MS4).
The Ballona Creek Enhanced Watershed
Management Program (EWMP) and the Marina
Del Rey EWMP associated with the aforementioned
watersheds, have each been adopted by the Los
Angeles Regional Water Quality Control Board
(RWQCB) as compliance pathways for the 2021
Regional Los Angeles MS4 Permit (ORDER NO.
R4-2021-0105 NPDES PERMIT NO. CAS004004), of
which the city is a permittee. The city has already
achieved compliance targets for the Marina Del
Rey watershed.
