Bolivar Park Stormwater and Runoff Capture Project, City of Lakewood, Lakewood, CA. Structural Design Engineer. Providing design phase services including plans, specifications and estimates. Tetra Tech was contracted to evaluate the potential site location and develop this stormwater runoff and capture project. The project consists of an air -inflated rubber dam diversion system to re -direct all urban runoff and stormwater runoff from the Del Arno channel through a pre- treatment system to remove trash, debris, and sediment. A pump station and drainage pipeline will convey the water into a large, buried multi- chambered storage/infiltration facility. The stormwater collected in the underground reservoir will be treated and used to irrigate the park's landscaped areas. The system will monitor the weather conditions and the facility through a secured cloud -based system. The underground storage system is 2.8 million gallons (8.7 ac-ft). The goal of the project is to not only help the City comply with the metals Total Maximum Daily Loads (TMDLs), as presented in the Los Cerritos Channel Watershed Management Program, but also provide additional benefits, such as revitalized park infrastructure and augmentation of local water supplies.
