objective of the project is to improve Santa Monica beach water quality by increasing the diversion capacity at the Santa Monica Pier and Pico-Kenter storm drain outfalls. The 85th percentile storm event volume would be treated and diverted from the Pier watershed to the Santa Monica Urban Runoff Recycling Facility (SMURRF) or the sanitary sewer. The project proposes storm drain diversion and runoff storage systems at two separate storm drain outfalls. Culver Boulevard Stormwater Infiltration and Retention Project, City of Culver City, CA. Design Engineer. Responsible for preparation of design specifications for this multi -beneficial stormwater regional project. Tetra Tech was recently selected by the City of Culver City to provide design services to incorporate an infiltration gallery under a newly reconstructed raised median along Culver Boulevard. The project will also include retention basins to reuse captured stormwater runoff and urban runoff to irrigate local landscape medians within the project area. The overall landscape design of this project will include green elements such as bioswales along the raised median and adjacent roadways to further promote stormwater pollution prevention education Caruthers Park Stormwater and Urban Runoff Capture Project, City of Bellflower, Bellflower, CA. Design Engineer. Providing engineering design support for this Caltrans funded stormwater capture project. Tetra Tech is providing a Project Engineering Study Report (PESR) that includes all necessary analyses to provide a recommendation for regional stormwater capture treatment and implementation. The analysis identifies the existing site hydrology, water quality, and hydraulics to determine an optimal combination of the inflow rate, storage volume, and outflow. The Caruthers Park Project consists of a gravity diversion from two separate Los Angeles County Flood Control District storm drain lines; a 72" RCP line that drains 261 acres of the Los Cerritos Channel, and a 38' wide rectangular concrete channel that drains 2,995 acres of the Lower San Gabriel River. The diverted flows pass through a pretreatment system to remove trash, debris, and sediment. The runoff is then passed into a large buried multi -chambered storage/infiltration facility that will be treated and used to irrigate the park. Flows in excess of the required irrigation demands will pass into the infiltration gallery to be exfiltrated through the soil to eventually combine with the ground water. It is anticipated that the system will use active controls to monitor the weather conditions and empty the facility through a secured cloud -based system. This project will help the City comply with their bacteria and metals TMDL, while providing additional benefits of potable water offset and park revitalization. Adventure Park Multi -Benefit Stormwater Capture Project, County of Los Angeles Department of Public Works, Whittier, CA. Design Engineer. Providing engineering design support for the development of 30% design plans for a 21.5-acre-foot regional stormwater capture BMP. Tetra Tech is currently preparing a preliminary design concept report which will include the 30% design level documents. The primary goal of the project is to implement watershed control measures and structural Best Management Practices (BMPs) to address the water quality objectives for the region while incorporating additional project benefits such as Low Impact Development (LID) measures and sustainable landscaping in the park. This project is a major step towards implementing the Upper San Gabriel River (USGR) Watershed Management Area Group's Enhanced Watershed Management Program (EWMP). The goal of this project is to prepare preliminary design reports which will include 30% design level documents, and that could be utilized to support grant funding application and/or supporting information for a design -build solicitation package.
