Sun Valley Upper Storm Drain Project
The Sun Valley Upper Storm Drain Project is a critical component of the Rory M. Shaw Wetlands Park Project. This 4.75-mile long storm drain system will capture storm flows from the upper portion of the Sun Valley watershed and deliver the stormwater to the future wetlands park facility. The stormwater will be stored in a detention pond, routed through engineered wetlands for pollutant removal, and used for groundwater recharge.
The new storm drain system is proposed along major streets in the Sun Valley community- Glenoaks Boulevard, San Fernando Road, Tuxford Street, and Tujunga Avenue. This project will be constructed sequentially in four phases.
Phase 1 Construction started in July 2021 and was field accepted in August 2023.
For questions regarding the future Phases 2-4, contact project manager Haitam Ali.
