Venice Pumping Plant Dual Force Main Sewer


The City of Los Angeles Department of Public Works has initiated an environmental review process for the proposed Venice Pumping Plant Dual Force Main project. The project includes a proposal to construct and install a new force main sewer extending from the Venice Pumping Plant at 140 Hurricane Avenue in Venice, to the North Outfall Sewer in Vista del Mar near Waterview Street in Playa Del Rey.


A New Force Main Is Needed Because:
  • During severe wet weather, peak flows to the Venice Pumping Plant have exceeded the capacity of the existing force main, which carries wastewater away from the plant.
  • Currently, all of the wastewater from the Venice Pumping Plant is carried in one sewer. As a result, that sewer cannot be shut down for maintenance.

A New Force Main, In Conjunction With The Existing Main, Will:
  • Expand capacity to ensure the continuous, safe flow during projected wet weather
  • Help prevent sewer spillage onto city streets and adjacent surface waters
  • Allow for much needed maintenance, rehabilitation and cleaning of the existing force main during dry weather


Proposed Alignment Alternatives


As a result of numerous technical studies, four proposed alignment alternatives are under consideration and will be evaluated in an Environmental Impact Report (EIR).

Marquesas Way/Via Marina – From the pumping plant on Hurricane Street, the alignment would proceed east under the Grand Canal and along Marquesas Way, then southeasterly on Via Marina to the Marina Del Rey entrance channel. It would then cross under the Marina del Rey and Ballona Creek channels and continue south within Pacific Avenue to a junction structure in Vista Del Mar near Waterview Street.

Pacific Avenue Alignment – From the pumping plant on Hurricane Street, the alignment would proceed westerly to Pacific Avenue, then turn south and proceed along Pacific Avenue, cross under the Marina Del Rey and Ballona Creek channels, and continue south within Pacific Avenue to a junction structure in Vista Del Mar near Waterview Street.

Dockweiler Beach to Pacific Avenue Alignment – From the pumping plant on Hurricane Street, the alignment would proceed westerly to the existing 20-feet wide sewer easement in Dockweiler State Beach, then turn south and cross under the Marina del Rey and Ballona Creek channels, and continue south of the channels within the Pacific Avenue alignment to a junction structure in Vista Del Mar near Waterview Street.

Dockweiler Beach Alignment – From the pumping plant on Hurricane Street, the alignment would proceed westerly to the existing 20-feet wide sewer easement in Dockweiler State Beach, then turn south and cross under the Marina Del Rey and Ballona Creek channels, and continue south along the Dockweiler Beachfront to a point west of the junction structure in Vista Del Mar near Waterview Street. From this point the line runs east to the junction structure in Vista Del Mar near Waterview Street. This alignment is about 11,000 feet long.


Construction Options

The four alignments under consideration cross the Marina entrance channel and Ballona Creek channel, requiring about 1,800 feet of tunneling under the two channels. Elsewhere along each alignment, two alternative construction methods are under consideration: open trench and tunneling. While the open trench method is less expensive, tunneling would eliminate the majority of traffic and parking impacts to residential areas both north and south of the channels, and can facilitate mitigation of other impacts such as noise.

Opportunities for Public Involvement


The City of Los Angeles Department of Public Works is sensitive to the needs of the community and wants to utilize an alignment and a construction method that minimizes impacts to surrounding neighborhoods.
