USACE Los Angeles District was involved in the development and execution of the Ed Pastor Keno Environmental Restoration Project. The project substantially improved the environmental quality of a mudflat basin, while maintaining the original function of detaining and storing flood waters from a 17.7 square mile watershed. The project has two primary functions -- flood control and ecosystem restoration. As a flood control facility, the project controls storm water discharge from the basin during storms. During non-storm events, water flow rates and water levels are controlled by a re-circulation system that includes a pumping station, distribution piping, solenoid valves, stream course weirs, and the deep pond inlet weir. The project’s natural and constructed aesthetic features, recreational benefits, and natural habitat have dramatically enhanced an economically depressed neighborhood.
