0 Bolivar Park Stormwater and Runoff Capture Project, City of Lakewood, Lakewood, CA. Survey Manager. Mr. Helt oversaw survey services for 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, 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. Mayfair Park Stormwater and Runoff Capture Project, City of Lakewood, Lakewood, CA. Survey Manager. Mr. Helt oversaw survey services for 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 Clark Channel through a pre-treatment system to remove trash, debris, and sediment. A drainage pipeline will convey the water into a large, buried multi -chambered storage and filtration 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 4.5 million gallons (13.8 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. Aliso Creek — Limekiln Creek Restoration Project, City of Los Angeles Bureau of Engineering, Los Angeles, CA. Survey Manager. Mr. Helt oversaw survey services for this project, located at the confluence of the concrete lined Aliso and Limekiln Creek flood channels. The project improvements involve constructing several stormwater Best Management Practices (BMPs) intended to treat on -site and off -site runoff and reduce contamination in Aliso Creek, Limekiln Creek, and the Los Angeles River. The proposed BMPs include low flow channel diversions, stormwater pump stations, stormwater pre-screening devices, bioswales, vegetated detention/retention basin, the restoration of upland, riparian habitat, and BMP educational signage. The goal of the project is to significantly reduce the pollutant loads, as well as transform a specifically built flood control facility into a multi -function green infrastructure facility. The project will also be designed to achieve a Platinum Envision Rating. Albion Riverside Park Project, City of Los Angeles Bureau of Engineering, Los Angeles, CA. Survey Manager. Mr. Helt oversaw survey services for the Albion Riverside Park Project. Tetra Tech provided design and construction support services for this project located adjacent to the Los Angeles River, which involved transforming a six -acre site, previously used for dairy warehousing and distribution, into a riverfront park and recreational facility that will benefit nearby disadvantaged low- income neighborhoods. In addition, the City is using the redeveloped property to increase the current capacity for managing stormwater runoff. This important water quality project is part of the City's overall efforts through the Proposition O Bond Program to improve water quality and reduce pollutant loads that are currently being conveyed to the rivers, lakes, and oceans within the greater Los Angeles area. In addition, the project is being designed to achieve a Platinum EnvisionTm rating. City of Santa Ana 2
