EXPERIENCE <br />Bolivar Park Stormwater Capture Project <br />Lakewood, CA <br />Tetra Tech was contracted by the City of Lakewood to evaluate two <br />potential site locations for the development of the Lakewood Stormwater <br />and Runoff Capture Project: Mayfair Park site and the Bolivar Park site. <br />Tetra Tech provided a Project Engineering Study Report (PESR) that <br />represented 10% design completion level and described the evaluation of <br />the two sites with all site investigation, hydrology and hydraulic, and water <br />quality data and analyses to provide a recommendation for site selection. <br />The Bolivar Park project consisted of an air -inflated rubber dam diversion <br />system to redirect all urban runoff and stormwater runoff from the Del <br />Amo channel through a pre-treatment system to remove trash, debris, <br />and sediment. A pump station and drainage pipeline will then convey the <br />water into a large, buried multi -chambered storage/infiltration facility. The <br />stormwater collected in the underground reservoir will be treated and used <br />to irrigate the park's landscaped areas. The system will monitor the weather <br />conditions and the facility through a secured cloud -based system. <br />The goal of the project was to not only help the City comply with the metals <br />Total Maximum Daily Loads (TMDLs), as presented in the Los Cerritos <br />Channel Watershed Management Program, but also provide additional <br />benefits such as revitalized park infrastructure and augmentation of local <br />water supplies. As one of the first cities to receive stormwater funding to <br />support Caltrans with stormwater compliance units, the success of this <br />project serves as a model for other agencies to follow. <br />This project received the 2018 APWA Best Award in the Storm Water <br />Quality category, and was selected to receive the CASQA Project of the <br />Year awarded in October 2019. <br />City of Santa Ana 25F-35 TETRA TECH <br />
