ASCE Metropolitan Los Angeles Branch (MLAB) & ASCE – Los Angeles Section (9 Counties) Level
To minimize potable water use, Earvin “Magic” Johnson Park was re-engineered by PACE to provide a sustainable new water source using a unique stormwater management system to recycle the runoff from the 375-acre watershed. This system captures and treats runoff (dry and wet weather flows) to improve water quality. The stormwater runoff is then directed to a biofiltration area in the form of mitigated wetland surrounding one of the park’s two lakes. The filtered stormwater water fills the lake and is then recirculated to irrigate the Park. This 21st-century park addresses how Southern California might implement the capture and reuse of our stormwater runoff and adds a much-needed amenity to an underserved community.
