Welcome to SunValleywatershed.org

The mission of the Sun Valley Watershed Stakeholders Group is to solve the local flooding problem while retaining all stormwater runoff from the watershed, increasing water conservation, recreational opportunities, and wildlife habitat, and reducing stormwater pollution.

 

There's something exciting going on in Sun Valley! A serious effort to solve the area's chronic flooding problem is underway, but that's not the half of it. Planners envision a solution that will bring many other benefits to the community as well. The implementation here of what's known as a "watershed approach" to urban environmental problems could focus regional and national attention on Sun Valley. On this website, we'll provide both an introduction to the Sun Valley Watershed Project and a clearinghouse for project information. We hope you'll find the site informative and useful - maybe even inspiring!

Sun Valley is a district of the northeast San Fernando Valley, known to many Angelenos as the site of gravel pits and innumerable media stories about seriously flooded intersections. As they do in much of the urban area, hard surfaces dominate the Sun Valley landscape and prevent the ground from absorbing stormwater runoff. But Sun Valley lacks the infrastructure that, in much of the city, quickly carries runoff to the ocean. The result is a chronic flooding problem that often inconveniences and sometimes endangers the area's 80,000 residents.

Stormwater runoff in urban areas is the focus of a lot of regulatory attention these days because all those hard surfaces aggravate downstream flooding and contribute pollutants to our streams and the ocean. For these reasons, among others, traditional storm drains are no longer considered the best way of managing stormwater, and local government agencies are working to find effective alternatives.

Those agencies, along with area residents, businesses and environmental groups, have come together to develop a flood control plan for Sun Valley that will also address water quality issues, while providing a number of additional benefits to the community - benefits such as water conservation and more space for recreation and wildlife habitat. Monthly meetings of the Sun Valley Watershed Stakeholders Group are facilitated by the County of Los Angeles Department of Public Works, which is taking the lead on this innovative project.

The Department has hired a consultant team that includes the engineering firm Montgomery Watson Harza and the environmental nonprofit group TreePeople. The team is working on a watershed management plan to meet the goals outlined in the Group's mission statement, printed above. The team is also charged with outreach and public education tasks - understanding local concerns, informing residents of the underlying issues and promoting the benefits of a multipurpose plan.

The selection and design of several pilot projects in the watershed, the development of this website, and the publication of the Watershed Events newsletter are among the team's early efforts. All of our efforts are aimed at developing multipurpose projects to control the flooding in Sun Valley, while improving the community in other ways as well. We need your support, and we'd appreciate hearing your ideas and concerns. Find out about opportunities to learn and to help under Resources and Get Involved.

  Flood Problems

Flooding is a serious problem in Sun Valley; the San Fernando/Tuxford intersection is one of the perennial trouble spots.

Gravel Pit

Many ideas will be considered on the way to solving Sun Valley’s flooding problem. Here, an L.A. County Department of Public Works artist has depicted a stormwater retention basin and park in a worked-out gravel pit.

Pan Pacific Park

Pan Pacific Park is an example of the sort of multipurpose solution we envision for Sun Valley. A key element of County Public Works’ flood-control plan for the Fairfax District, the park can hold large amounts of stormwater when necessary.

Underground Infiltration

Underground infiltration basins can also help reduce flooding. They capture stormwater and hold it for absorption by the ground.

Sun Valley Recreation Center

The Stakeholders Group is considering an infiltration project at Sun Valley Park & Recreation Center. It could reduce flooding in the neighborhood without using up valuable recreation space.
