A 15-acre manmade lake was developed to serve as the heart of the master-planned Bridgeport community in northern Los Angeles County. In addition to being the focal aesthetic feature of this high-end development, the lake system also serves as the primary drainage facility for the site and as a water quality and urban storm runoff enhancement facility. Bridgeport Lake incorporates a unique system of aeration, biofilters, water quality filters, and wetland planter areas to manage runoff and maintain water quality, filtering out pollutants prior to lake discharge. Through a unique combination of natural and engineered processes, Bridgeport Lake successfully combines a recreational amenity and environmental habitat with stormwater conveyance for the community, a stormwater runoff retention and treatment system, and lake water quality management system. The Bridgeport Lake system fulfills the post-construction requirements of the NPDES permit and associated SWPPP for the Bridgeport development. Additionally, by incorporating stormwater conveyance and treatment, large storm drain pipes were eliminated from the development and stormwater is treated prior to discharging to the adjacent Santa Clara River. The lake has a retention capacity (first flush) of 3.75 AF, all of which is routed through a water quality filter system. The lake’s sophisticated water quality treatment system includes biofilters ad aeration to maintain existing water in the lake and any runoff that flows directly into the lake.
