Woodside Water Quality Basin Modifications & Trash Capture Project

The Woodside Water Quality Basin Modifications & Trash Capture Project is expected to begin construction by the end of 2026.

The project will divert additional stormwater runoff during low flow periods into the existing basin for treatment and modify outlet structures to increase infiltration and improve stormwater management performance. In addition, a full capture trash screen that meets California’s requirements will be retrofitted onto the existing trash racks.

Once complete, the project will filter runoff diverted into the basin from its 883 acre drainage area and capture approximately 1,000 gallons of trash and debris per year, improving water quality in the San Diego River watershed.

Note that project details and timelines may change as construction moves forward.

Construction: What to Expect

Construction is estimated to begin in December 2026. 

Please note that construction dates are subject to change due to compliance requirements, inclement weather, and/or other unforeseen circumstances. 

During construction, the County will make every effort to minimize disruptions in the surrounding area. The work will occur within the County of San Diego’s Woodside Avenue Flood Control Facility.
