The Work We Do

The District’s planning efforts support early analysis of flood risks and help prioritize the most effective improvements. See the data guiding current work and future investments.

Western Alameda County is divided into nine flood control zones that are generally defined by watershed boundaries. Find your zone and learn about the capital projects happening in your neighborhood.

Clean, reliable water is vital for healthy communities and thriving ecosystems. However, urban runoff pollution and reduced flows during drought put increasing pressure on local water resources. To address these challenges, the District manages programs focused on protecting water quality and promoting smarter water use. 

The District’s Maintenance and Operations (M&O) Department is responsible for the day-to-day inspection and maintenance of more than 500 miles of conduit, channels, and natural creeks throughout western Alameda County. Learn more about our Maintenance and Operations team on our Departments page.
