November 2024 Update

The project is in the Design phase. Coordination with Los Angeles County Sanitation District and SoCalGas ongoing. Construction is expected to begin Winter 2024/5.

SoCalGas utility relocations:

• Relocation #1 along Pacific Avenue from Valley Drive to 27th Street.
  • Status - Completed April 2024. 
• Relocation #2 on Ardmore Ave between Pacific Ave and Laurel Avenue.
  • Status - Under construction. Notice street closure Monday - Friday on Ardmore between Pacific Avenue and Laurel Avenue. See map below.

Sanitary sewer lift (pump) stations are complex facilities with auxiliary systems designed to move wastewater from lower to higher elevations through a force main pipe. Pump stations must be monitored and maintained regularly to ensure a reliable operating condition. Key elements of lift stations include a wastewater receiving well (wet-well), often equipped with a screen to remove coarse materials; pumps and piping with associated valves; motors; a power supply system; an equipment control and alarm system; and an odor control system and ventilation system. Lift station equipment and systems are often installed in enclosed concrete underground structures. Underground sewer pump station concrete structures typically last 50 to 100 years, with internal mechanical and electrical equipment lasting 15 to 20 years. The Pacific Avenue Sewer Lift Station structure, located at 2803 Pacific Avenue, was initially constructed in the early 1950s and has reached its useful life at nearly 70 years old. Mechanical and electrical upgrades were implemented approximately 25 years ago, around the late 1990s. Once exceeded, these facilities become less reliable, expensive to maintain, and are subject to failure.

City Council approved the preliminary engineering study for the Pacific Avenue Sewer Lift Station. The preliminary engineering design work has been completed, and its findings are detailed in the final draft Basis of Design Report (BODR). The BODR is the first primary deliverable for the project design. It identifies improvements needed to provide greater emergency storage capacities, pumping capacities, and other enhancements for the existing sewer lift stations site. The purpose of the respective BODR is to help City Council identify and consider a practical and cost-effective upgrade option. Specifically, for the Pacific Avenue site, staff was able to identify a viable alternative to remove the current station from service by constructing a gravity sewer main connection to an existing Los Angeles County trunk sewer gravity system at the Ardmore and Pacific Avenue intersection, thereby significantly reducing the risk of sewer spill and reducing the operating and future capital replacement costs. This option can be implemented to eliminate the requirement for the complete rehabilitation of the station. Site improvements will also be included in the project and detailed in the Final Design phase.
