water quality features within the project limits. As such, the project Included a blo-retention parkway approximately 650 -feet long by 15 -feet wide. Additional Improvements included hardscape enhancements, such as boulders and cobble stone, decorative crosswalk designs, street furniture and related bike and equestrian amenities, decorative fencing, and street/trail way -finding and Interpretive signage. Carriage Crest Park, City of Carson, Carson, CA, Project Engineer, Mr. Hohnbaum Is providing design services to prepare final plans, specifications and estimates (PS&E's) for the 100% design of the project. Tetra Tech was contracted to provide a Project Engineering Study Report (PESR) that represents 10% design completion level and describes the evaluation of the site including all site investigation, hydrology and hydraulic., and water quality data and analyses to provide a recommendation for BMP selection. Subsequent to the PESR, Tetra Tech is contracted to provide design services for the plans, specifications, and cost estimates (PS&E's) for the 100% design, The design for Carriage Crest Park was prepared in accordance with the City of Carson's contributions to the Dominguez Channel Watershed Management Area Group Enhanced Watershed Management Program. In order to meet the goals of the PESR, the project implemented an underground diversion structure which diverts runoff through a pretreatment device prior to discharging to an underground reservoir. A pump station then discharges the captured runoff into a sewer line during off peak hours to be treated and potentially used as reclaimed water. Caruthers Park Project, City of Bellflower, Bellflower, CA. Project Engineer. Mr. Hohnbaum Is currently providing design services to prepare final PS&E's for the 100% design of the project. Tetra Tech was contracted to provide pre - design, design, and construction support services for this Caltrans funded stormwater capture project. Tetra Tech is providing a Project Engineering Study Report 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 burled mufti - chambered storage/inflhration facilitythat 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 exflltrated 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. 25F-59 Bolivar Park Project, City of Lakewood, Lakewood, CA. Project Engineer. Mr. Hohnbaum Is responsible for the design services to prepare final plans, specifications and estimates as well as the construction services which Included technical support and guidance while reviewing, approving, and respondingto construction submittals and RR's. 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 Amo 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, burled mufti - 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 securedbloud-based system. The underground storage system Is 2.8 million gallons (8.7 ac -ft).
