Project 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 consist of 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 from 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 from pollutants before it discharges to the curb and then into the storm drain system.

 


Project Details

The project integrates 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 chamber with diversion pumps and electrical upgrades that will divert the stormwater runoff from the roof and parking drainage areas into the sanitary sewer.

Project Status

The project is scheduled to advertise for construction bids in August 2026. Construction is anticipated to start in the Fall of 2026 and end be completed in the Spring 2027.
