Multi-Benefit Project

The potential project proposes to collect stormwater runoff from the upstream 110-acre drainage area and convey them into an underground retention basin at Ladera Park. The runoff from the drainage area can be used for irrigation purposes or be infiltrated into the ground.

The proposed project is in the preliminary phase and entails the construction of a diversion from existing storm drains to an underground infiltration gallery below the park open space. Recreational use will be maintained, bio-swales will be installed along Quincy Street, and groundwater recharge will occur via the underground infiltration gallery. The project will incorporate outreach signage in the community center and the park to educate the community on the benefits of the project.

The proposed project would collect dry weather runoff and stormwater from approximately 200 acres of the County unincorporated community of Florence-Firestone and allow it to soak into the ground. The project will protect the water quality of local rivers and streams, increase the local water supply, and enhance park amenities.

The proposed project will construct a green street to collect dry weather runoff and stormwater that flows through 103rd Street and portions of Ted Watkins Park. The green street infrastructure will be accompanied by street rehabilitation, including improved sidewalks, curbs, and asphalt pavement. The project will protect the water quality of local rivers and streams, and provides multiple enhancements to the street and its users.

The planned project proposes to collect stormwater runoff from the upstream 105-acre drainage area and divert flows into an underground cistern under Gates Canyon Park. Runoff from the drainage area will be saved and treated for irrigation purposes or be infiltrated into the ground. Retention of storm water also helps alleviate flood risk in the downstream flood control system. This project is currently in the planning phase.

The proposed project will capture and divert urban and stormwater runoff from the existing DDI 23 stormdrain into a pre-treatment system, then into underground infiltration best management practices below medians along Northside Drive and Southside Drive in the unincorporated County area of East Los Angeles. The project will improve stormwater quality by preventing stormwater pollutants from ultimately discharging into to the Los Angeles River. In addition, the project will increase local water supply through infiltration into the groundwater basin, provide community enhancement, and provide educational and outreach opportunities.

The Alondra Park Multi-Benefit Stormwater Capture Project is located in the unincorporated area of El Camino Village, Lawndale, CA. The Project will capture, pretreat and store 34 acre-feet of urban runoff and stormwater from 4,495 acres of residential, commercial, and industrial land. It will then divert the stored water to a nearby sewer trunk line, or treat it and release it back to the storm drain.

The proposed project will collect and divert stormwater runoff from the upstream 228-acre drainage area into an underground infiltration system located at Monteith Park and a nearby alley that will percolate into the ground. The project will prevent potentially polluted runoff from being discharged downstream thus improving the water quality in the Ballona Creek Watershed. In addition, the project will also include LID, drought tolerant landscaping, recreational, education, and aesthetic benefits.

The proposed project is located in the unincorporated County community near Viewridge Rd and Topanga Canyon Blvd and serves to improve water quality in Topanga Creek and North Santa Monica Bay while enhancing the community. Features of the project include new drainage infrastructure to capture and treat urban and stormwater flows, a new 600-foot vegetated median, numerous innovative low-impact-development (LID) landscaped parkways, additional trees, drought tolerant plants, drip irrigation, and educational signage.

The proposed project is located on a 15.5-acre parcel in the unincorporated county area of Whittier, and serves to improve water quality and supply, as well as enhance the open park area. The project will collect up to 50 cubic feet per second of stormwater runoff from Sorenson Drain, and convey it to a pretreatment system under Adventure park grounds prior to diversion to a sewer main.

The proposed Project will divert, treat and infiltrate stormwater from a 1,146.5-acre tributary area by means of eight diversion structures to reduce pollutants entering the San Gabriel River, thus improving water quality. Stormwater will be directed to an infiltration gallery system located at a Bassett High School open field, which will be accompanied by baffle filtration units to pretreat flows. The Project will also feature drought tolerant landscaping with educational signage, enhanced athletic fields, and a pocket park open for public use.

The proposed Project includes construction of a new 0.5-acre park with a staff office and public restroom building, playground areas, splash pad, an open lawn area, and additional park amenities. The stormwater capture elements include a diversion system and infiltration dry wells to divert and capture both urban and stormwater runoff from a 27-acre drainage area in the unincorporated community of Walnut Park.
