Project: Santa Margarita Water District Prop 1E Gobernadora Multipurpose Basin Project Grant Proposal

Description: The Project will consist of an urban runoff and storm/flood detention basin that will be established as a wetland and riparian habitat, a collection system to capture and divert flows from the constructed wetlands, a pump station and pipeline to connect to the existing Portola Reservoir system.
