Multi-Benefit Projects
In-Progress
Puente Creek Greenway and Bikeway Project
San Gabriel River Watershed
The project will create new bicycle and pedestrian connections along Puente Creek, providing safer and more convenient opportunities for walking, biking, and recreation in the communities of Valinda, La Puente, and Industry. Improvements include approximately 1.8 miles of off-street multi-use trail within the flood control right-of-way, as well as 1 mile of on-street bike routes on nearby local streets where trail construction is not feasible.
The project will also enhance the corridor with native and drought-tolerant landscaping, new fencing and access gates, wayfinding signage, and a rest area with seating and shade amenities. In addition to improving access and mobility, the project will beautify the flood control corridor, support local habitat, and advance implementation of the San Gabriel Valley Greenway Network.

Los Angeles River and San Gabriel River Interceptor Project
Los Angeles River & San Gabriel River Watersheds
The Los Angeles and San Gabriel Rivers are two significant waterways within LA County, supporting dozens of communities as vital natural resources, recreational corridors, and flood control channels for millions of residents. The rivers face ongoing challenges from trash, debris, and illegal dumping that threaten water quality, public safety, wildlife habitats, and community enjoyment of these spaces. To help address these issues, LA County Flood Control District has partnered with City of Long Beach and The Ocean Cleanup to implement the Marine Trash and Debris Capture Project to install additional downstream trash booms to capture debris from the Los Angeles River. Similarly, LA County Flood Control District has partnered with City of Seal Beach and The Ocean Cleanup to enter an agreement for a pilot trash interceptor project in the downstream area of the San Gabriel River. Both efforts aim to help capture trash, plastic, and litter before reaching the ocean.
Project Timeline: Deployment of pilot program anticipated by spring 2028
Vincent Community Bikeway and Greenway Project
San Gabriel River Watershed
The Project spans ~2 miles along Big Dalton Wash and improves the aesthetics of the channel right-of-way, provides habitat enhancements and recreational opportunities, improves the safety of pedestrians and bicyclists, and creates an additional mode of travel for surrounding communities. Greenway amenities include native and drought-tolerant landscaping, irrigation, wayfinding signage, decorative access gates, and ~8,000 linear feet of 8-foot-high welded wire fencing to replace the previous chain link fence. The Project also includes pavement along the access road, traffic striping, retaining walls, ADA-compliant access ramps, and pocket parks at two entrances that include benches, drought-tolerant plants, decomposed granite trails, and trash receptacles. The Project is a result of a partnership between LA County, the Flood Control District, SD1, and local Cities, and is also an early implementation project of the San Gabriel Valley Greenway Network.

Baldwin Lake and Tule Pond Restoration Project
Rio Hondo Channel Watershed
The Baldwin Lake and Tule Pond Restoration Project at the Los Angeles County Arboretum in Arcadia is a partnership between the Los Angeles County Flood Control District, the Department of Parks and Recreation, and the Arboretum Foundation. The project will restore Baldwin Lake by dredging to increase capacity, installing a liner to reduce seepage, adding aeration and algae control systems, and improving the shoreline with new landscaping, irrigation, and an educational viewing deck. Tule Pond will be regraded and dredged to restore its role as a stormwater infiltration and pre-settling basin, capturing flows and reducing sediment and trash before water reaches Baldwin Lake and Arcadia Wash. Landscaping and irrigation upgrades will also improve the pond area. Together, these improvements will enhance water quality, habitat, and recreation for more than 500,000 annual visitors, including students from predominantly Title I schools, with funding from the Flood Control District, the Safe Clean Water Program, and Proposition A Excess Funds.

Los Angeles River Headwaters Pavilion Project
Los Angeles River Watershed
The proposed project is located in Canoga Park, at the intersection of Bassett Street and Alabama Avenue, and would construct a Tier II Pavilion stemming from the LA River Master Plan Update. The project will serve as an entryway access point to the LA River trail and provide various amenities such as seating, educational signage, drinking fountains, restrooms, trash receptacles, and water quality improvements.
Rory Shaw Wetlands Park Project
Los Angeles River Watershed
The project will convert a 46-acre former debris landfill into a multi-benefit park and stormwater capture facility. Working in tandem with the Sun Valley Upper Storm Drain System, the facility is designed to capture and manage stormwater runoff from a 929-acre upstream tributary area. By naturally treating and infiltrating this urban runoff, the project aims to reduce regional flood risk, boost local water supply through groundwater recharge, and create open space for the Sun Valley community. While the District explores optimized engineering alternatives to maximize cost-effectiveness, interim site improvements have been implemented to ensure the property remains safe and visually pleasing.

Sun Valley Upper Storm Drain Project
Sun Valley Watershed
The Rory Shaw Park Storm Drain Projects (Formerly Sun Valley Upper Storm Drain, Phases 1- 4) will work in tandem with the Rory Shaw Park Project to address localized nuisance flooding in the community of Sun Valley, Los Angeles. This 4.75-mile storm drain system will capture stormwater runoff from the upper 929-acre tributary area and convey it to the Rory M. Shaw Wetlands Park. Phase 1 of the Project was completed in August 2023.

Completed
Dominguez Gap Wetlands Project
The project converted an existing, 37-acre, spreading ground basin into a multi-benefit wetlands. Flows from the LA River and local urban runoff are routed through the basin to sustain a year-round habitat for plants and native wildlife. The open space provides increased opportunities for public recreational amenities, such as an equestrian trail, bike path and walkways.
Ballona Creek Interceptor Project
Ballona Creek Watershed
This project uses an automated, solar-powered floating trash collection system near the mouth of Ballona Creek to capture plastic, trash, and litter before it reaches Santa Monica Bay and the ocean. The Interceptor was deployed in October 2022 as a pilot project and, following successful completion of the pilot, was approved for ongoing operation as an official project in October 2024. Floating booms guide debris to the Interceptor, where it is collected for removal, helping improve water quality, protect beaches, and reduce stormwater pollution.
Oxford Retention Basin Multi-Use Enhancement Project
Marina Del Rey Watershed
This project improved the Oxford Retention Basin in Marina del Rey to enhance flood control, water quality, wildlife habitat, and public access. Construction began in 2015 and was completed in May 2016, followed by a ribbon-cutting and reopening on July 7, 2016. The project removed accumulated sediment, improved water circulation, added native landscaping and habitat areas, and created walking paths, observation areas, lighting, fencing, and interpretive signage for the community.
