City of Pasadena Invites Community to Share Input on Brookside Park Stormwater Capture Project

The City of Pasadena invites the community to help shape the Brookside Park Stormwater Capture Project, which is designed to address critical water quality challenges while enhancing Parking Lot I at Brookside Park. Pasadena residents are encouraged to share their input by completing a community survey by Friday, August 1st, to inform the design of above-ground improvements for the project.

The Brookside Park Stormwater Capture Project will improve water quality in the Arroyo Seco and Los Angeles River while increasing water supply by recharging Pasadena’s Raymond Basin. The project, located just south of the Rose Bowl in Lot I, adjacent to Brookside Park, will integrate both underground green infrastructure and above-ground improvements to improve stormwater and urban runoff.

This comprehensive system will divert flows from the historic Seco Street Drain through a series of below ground treatment components, including a pre-treatment unit, before reaching an 11-acre-foot subsurface infiltration gallery. Above ground nature-based solutions, including bioretention cells, shade trees, and vegetated bioswales, will improve surface runoff pollution. Collectively, this project aims to capture, treat, and infiltrate stormwater and dry weather runoff from over 1,100 acres of the city, returning a portion of treated water to the Arroyo Seco Channel, to maintain ecosystem health and address water quality improvement goals.

The project site also offers the opportunity to improve and enhance Parking Lot I at Brookside Park. Various above-ground improvements will be considered and refined through input from the community, key stakeholders, park users, and the City during the collaborative design process.

The Department of Public Works is leading this design with funding from the Los Angeles County Safe, Clean Water Program (SCWP) Measure W regional grant program. The SCWP provides local, dedicated funding to increase local water supply, improve water quality, and protect public health. A feasibility study to develop the original concept was funded by the City’s Measure W Local Returns.

Residents interested in providing input can complete the survey at bit.ly/BrooksideParkProject or bit.ly/BrooksideParkSurvey.
