LA County awards $24 million for stormwater capture projects in six cities

Six cities in Los Angeles County’s Fourth District will receive a combined $24 million in grants to advance local stormwater capture and water quality improvement projects, Supervisor Janice Hahn announced this week.

The funding, awarded through the Safe, Clean Water Program, will support new stormwater infrastructure in Downey, Long Beach, Lynwood, Norwalk, Paramount and Signal Hill. The program is funded by revenue from Measure W, a parcel tax approved by voters in 2018 that generates about $285 million annually for projects improving local water supply and resilience.

“These projects are investments in the future of LA County,” said Hahn in a press release. “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.”

The Stormwater Investment Plans for Fiscal Year 2025–26, which include these allocations, were approved unanimously by the LA County Board of Supervisors on November 4.

Project highlights

• Downey – Furman Park Stormwater Capture and Infiltration Project ($5.4 million)
  This regional project will enhance flood management through new stormwater infiltration infrastructure. The work will also include sports field upgrades, new exercise equipment, and recycled water irrigation.

• Long Beach – Municipal Stormwater Treatment (LB MUST) Phase 2 ($3 million)
  The project will improve water quality and increase local supply by adding a pump station and cistern within a new park, while connecting five existing pump stations to the LB-MUST facility.

• Lynwood – City Park Stormwater Capture Project ($1.25 million)
  Designed to improve discharges to the Lower Los Angeles River, the project includes two stormwater diversion structures, parking lot upgrades, an ephemeral stream, and a butterfly garden.

• Norwalk – Hermosillo Park ($7.26 million)
  The park will receive an underground 11.8-acre-foot infiltration gallery with water reclamation capabilities to enhance water quality in Coyote Creek and the San Gabriel River. New soccer fields will be built above the system.

• Paramount – Spane Park ($5.41 million)
  During upcoming park rehabilitation, the city will install a 3.5-acre-foot regional stormwater capture and infiltration facility to improve water quality and support reuse.

• Signal Hill – Reservoir Park Stormwater Capture Project ($1.92 million)
  This project includes a new stormwater filtration system, along with upgrades to park equipment and the addition of a community garden.

Hahn noted that the projects reflect residents’ continued commitment to sustainable water management. “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,” she said in a press release.

The Safe, Clean Water Program continues to fund stormwater and water quality improvement projects across Los Angeles County, helping cities modernize infrastructure, enhance public spaces and strengthen regional water resilience.
