The Alondra Park Multi-Benefit Stormwater Capture Park (Project), located in the Unincorporated Los Angeles County area of El Camino Village (3850 Manhattan Beach Blvd, Lawndale, CA 90260), will revitalize an existing park with new stormwater infrastructure, new soccer and multi-purpose turf fields, and two rehabilitated baseball fields. The Project will capture and treat dry-weather and stormwater runoff from a 4,495-acre drainage area, with up to 40 acre-feet of runoff during a single storm event, by retaining runoff in a subsurface storage system. Captured runoff will be diverted to the sewer system during off peak hours and excess flows will be treated and released back into the storm drain system. The Project will capture flows from the Cities of El Segundo, Hawthorne, Lawndale, Manhattan Beach, and Redondo Beach, along with Unincorporated County areas. The Project also includes nature-based solutions with the planting of native and drought-tolerant vegetation and trees, bio-swales, and permeable pavements that mimic natural processes, which will improve stormwater quality by preventing stormwater pollutants from ultimately discharging into to the Dominguez Channel.
