One of the largest in the LA Basin, the Upper Los Angeles River spans the San Fernando Valley into the Angeles National Forest in the San Gabriel Valley and dips down into part of South LA, including Watts, Westmont and Willowbrook. In all, it encompasses 12 municipalities and unincorporated areas of Los Angeles County.

Although this watershed includes many urbanized areas, it has a surprising amount of biodiversity including hundreds of species of native plants, fish, insects, birds, and mammals. The vast aquifers and soil type of this watershed allows for a range of possibilities to increase water supply and improve stormwater quality. This watershed is also one of the most economically diverse in the LA Basin.

Meaningful engagement with the Upper LA River Watershed communities is key to effective stormwater management. As Watershed Coordinators, we connect communities, organizations and interested parties with the Safe Clean Water Program. Together we help advance multi-benefit projects that align community needs with Safe Clean Water Program Goals.

  • Kayaks in the Upper Los Angeles River (LA County Public Works)
  • The smaller ‘pocket’ parks in this region, such as Augustus Hawkins Park, make a huge impact on improving environmental quality in urban neighborhoods.

  • Featured Project

    Metro’s Active Rail Project – Segment A

    This project consists of one corridor in two phases of development—Segment A is the Rail to Rail component and Segment B is the Rail to River component. Together they form one route, stretching from South Los Angeles to the Los Angeles River. The project provides improved water quality, increased local water supply and reduced green house emissions. The project also includes construction of paved pedestrian and bicyclists pathways adjacent to landscaped areas that capture, bio-filter and infiltrate stormwater. 

    • New bike paths and pedestrian walkways for residents
    • Increases local water supply
    • Captures stormwater runoff
  • community members on a tour of Nogales park
    Featured Project

    Nogales Park Stormwater Capture Project

    Nogales Park Stormwater Capture Project transformed a 0.5 acre vacant lot into a vibrant new community park in a critically park poor community. The project was completed in 2024 partially funded through the Safe Clean Water Program in FY 20-21. The park provides recreational amenities including a playground area, fitness station, a splash pad, and other amenities that expand recreational opportunities. Beneath the surface, the park showcases innovative stormwater management solutions. The stormwater system includes a pretreatment device and drywells designed to capture and infiltrate stormwater runoff. These features enable the park to capture and infiltrate more than 450,000 gallons of water during a single storm event. 

    • New park and green space for residents
    • Increases local water supply
    • Captures stormwater runoff
  • Featured Project

    Earvin “Magic” Johnson Park Project

    This project is improving water quality and supply through the capture and treatment of stormwater and urban runoff, all while improving the open space and recreational amenities of the Park.

    • Protects the water quality of local rivers and streams
    • Minimizes potable water use
    • Creates a sustainable new water source
