Alameda County Flood Protection and Salt Pond Restoration

Alameda County Flood Protection and Salt Pond Restoration

The Alameda County Flood Control and Water Conservation District (District) is working to integrate three flood control channels with the large-scale restoration of the adjacent San Francisco South Bay Salt Pond Restoration Project (SBSP).

ESA has collaborated with the District to evaluate and recommend alternatives for connecting the Alameda Creek Flood Control Channel, a major flood control facility constructed by the U.S. Army Corps of Engineers and maintained by the District, to adjacent salt ponds in a way that facilitates the restoration of tidal wetlands and reduces fluvial flood hazards. We are developing design plans for the restoration of three salt ponds adjacent to the old Alameda Creek Flood Control Channel, a "Phase I" action identified under the SBSP project. ESA is leading hydrodynamic modeling, geomorphic analysis, and coordination with the SBSP project.

To better manage flooding in the tributary areas, ESA is evaluating the third flood control channel, Laguna Creek in Fremont, for integrating with the adjacent salt ponds to reduce flood hazard in the lower reaches.

ESA is working to plan, analyze, and design flood channel improvements with the large-scale SBSP restoration to improve flood protection and restore tidal wetlands along three District flood control channels.
