RECOMMENDATION
Staff recommends the City Council approve the final plans and specifications and authorize the publication of a notice inviting bids for the construction of the Transfer Station Stormwater Diversion Upgrades Project, PW-009.
BACKGROUND
The City owns and operates a 500-ton per day solid waste transfer station at 9255 West Jefferson Boulevard. The Transfer Station operates six days a week between the hours of 4:00 AM and 4:00 PM. Solid waste, recyclable materials and organics waste collected by City Environmental Programs and Operations Division (EPO) is tipped at the transfer station and transferred to tractor/trailer transfer trucks for transit to area landfills, materials recovery facilities, and compost sites. In addition, the City provides roll-off service for the collection of construction and demolition debris. All processing of materials functions is based at this facility.
The Transfer Station site is divided into four drainage areas. The existing stormwater diversion system captures urban run-off from two drainage areas into two underground storage chambers with a combined capacity of 30,000 gallons. The captured runoff is then pumped to the wastewater system and treated at the City of Los Angeles’ Hyperion Wastewater Treatment Plant. The stormwater diversion system prevents urban runoff pollutants from reaching Ballona Creek.
The other two drainage areas are the roof and parking areas. Currently stormwater runoff from these two drainage areas is treated and discharged into the storm drain system. As a result, the Transfer Station facility is subject to the NPDES Industrial stormwater general permit (IGP), WDID: 4 19I001571.
• The runoff from the roof drainage area is diverted into two cisterns. In a rain event where the cisterns are full, the runoff is diverted to bio-planters where it gets treated for pollutants. Once treated, the runoff is released to the curb and then enters the storm drain system.
• The runoff from the parking drainage area is diverted into two trench drains with filter medias where it gets treated for pollutants before it discharges to the curb and then into the storm drain system.
The City would like to integrate the drainage areas from the roof and parking areas into the stormwater diversion system, thus preventing stormwater runoff from entering the storm drain system and Ballona Creek. The upgrades include building additional onsite storage chambers with diversion pumps and electrical upgrades that will divert the stormwater runoff from the roof and parking drainage areas into the sanitary sewer.
DISCUSSION
On October 31, 2024, the City released a Request for Proposals (RFP #2539) seeking proposals from qualified vendors for engineering design services for the Transfer Station Stormwater Diversion Upgrades Project, PW-009. The City selected CWE Corporation to develop the Project design plans and specifications and an amendment to the existing professional services agreement with CWE was approved at the January 26, 2026 City Council meeting. The design plans and specifications have since been reviewed and approved by Culver City staff.
FISCAL ANALYSIS
The Adopted Budget for Fiscal Year 2025-2026 includes sufficient funding for construction in CIP Project PW009 (Transfer Station Stormwater Diversion) from the Refuse Disposal Fund (Fund 202) page 589 of the Capital Improvements section of the budget book in the Summary by Fund and Project.
