EXPERIENCE <br />Culver Blvd. Stormwater Filtration and Retention <br />Culver, CA <br />This project will maximize pollutant and stormwater capture by diverting <br />dry -weather and wet -weather stormwater flows at a rate of up to 50 cubic - <br />feet -per -second from two stormwater facility locations; a 66-inch reinforced <br />concrete pipe located at Harter Avenue and an 87-inch reinforced concrete <br />arch pipe located at Sepulveda Boulevard. Diverted stormwater flows are <br />first sent to one of two pretreatment units to remove trash and sediments <br />and then to a concrete underground storage facility capable of providing <br />up to 8-acre-feet of storage. Stored water is pumped to the post -storage <br />filtration system where it is polished for final pollutant removal before being <br />returned to downstream storm drain channels and receiving waters. As <br />an added benefit of this project, treated stormwater will be used to offset <br />potable water irrigation demands on the newly constructed 58-ft wide <br />raised landscape median and at nearby Veterans Park. <br />To reach a consensus with the residents for both projects, Tetra Tech <br />prepared a comprehensive Outreach Community Engagement Plan, <br />coordinated with the Citizens Advisory Committee, and participated in <br />community outreach meetings to encourage full and early community/ <br />stakeholder participation in the project. <br />Tetra Tech has completed the final design (PS&E) for these projects <br />and will continue to provide engineering support during construction. <br />Construction on this project occurred during late summer of 2019 and is <br />anticipated to be completed by the end of 2020. <br />City of Santa Ana 25F-38 TETRA TECH <br />
