Arroyo las Positas, Chain of Lakes, Livermore-Amador Valley
This project will coordinate land use development with the City of Livermore near the confluence of the City's golf course and Arroyo Las Positas to allow the ability to direct overland flood flows into the Chain of Lakes. This project will also widen Arroyo las Positas through the Golf Course. Widening will include, but not limited to the following: sediment removal, construction of sediment basin, and revegetation with native riparian habitat. As mitigation approximately 9 acres of wetlands will also be created.
