LOS ANGELES — Supervisor Janice Hahn has announced that 6 cities in her district have been awarded grants totaling $24 million from the County of Los Angeles for stormwater capture infrastructure projects.

The grants are part of the Safe, Clean Water Program paid for by revenue raised through the Measure W tax, approved by voters in 2018. Measure W generates about $285 million annually across LA County for projects to improve the local water supply.

In Supervisor Hahn’s Fourth District, grants were awarded to projects in the cities of Downey, Long Beach, Lynwood, Norwalk, Paramount, and Signal Hill.

“These projects are investments in the future of LA County. Not only will they allow us to capture, treat, and reuse millions more gallons of water, but they also give us an opportunity to improve our parks and make our green spaces more resilient for generations to come,” said Hahn. “Voters approved Measure W by a wide margin because they recognized the challenges of drought and water pollution—and these projects will help ensure we are better prepared to face them.”

The Stormwater Investment Plans for Fiscal Year 2025-26, which includes the funding for these projects, was approved unanimously November 4 by the Board of Supervisors.
