There are many different watersheds throughout Alameda County that overlap within cities and subregions. In order to make these watersheds easy to find and understand, The Alameda County Flood Control and Water Conservation District created full-featured, interactive maps of every watershed in the county.
The Alameda County Hydrology & Hydraulics Manual defines current practice in the hydrologic and hydraulic design of all District flood control facilities. Download the manual and accompanying GIS data here.
To help plan and deliver flood control and protection, Alameda County is divided into zones that generally follow major watershed boundaries. Explore an interactive map to learn more about flood control efforts and environmental restoration projects in your neighborhood.
The District works with a wide range of consultants and contractors. View current Requests for Proposals (RFPs), learn about the Small, Local and Emerging Business (SLEB) Program, and sign up to receive notifications about new business opportunities
Each year, the District publishes a report containing a comprehensive look at its work across Western Alameda County, including key project accomplishments, new initiatives, and a summary of how public funds were spent.
