Water Drop


The District collaborates with many partners and agencies on a wide variety of projects with mutual benefits.

Projects often involve complex and difficult decisions that may overlap with larger local or regional issues. Through these part-nerships, the best-possible solutions to the County’s flooding issues are derived.

Federal Partnerships

U.S. Army Corps of Engineers (USACE) San Francisco District

Since the District began building flood control infrastructure in the 1950s, the USACE has played an important role in developing and constructing Alameda County’s flood control system. The USACE built the Alameda Creek, San Lorenzo Creek, and San Leandro Creek flood channels.These channels are now maintained by the District.

The USACE is also the regulatory agency responsible for issuing permits for all structures and work on waterways within its jurisdiction, including dredging, marinas, piers, wharves, floats, intake/outtake pipes, pilings, bulkheads, ramps, fills, and overhead transmission lines.

Federal Emergency Management Agency (FEMA) National Flood Insurance Program We work with FEMA to assess and mitigate the risk of flooding in western Alameda County. Our work to update and digitize FEMA’s Flood Insurance Rate Maps (FIRMs) is an example of a cooperative project. FIRMs provide the most up-to-date boundaries of floodplain areas.

Other Federal Environmental Partners

We work routinely with the Natural Resources Conservation Service and the U.S. Fish and Wildlife Service to acquire regulatory permits for environmental restorations. We are currently collaborating with the National Oceanic and Atmospheric Administration (NOAA) as part of the Alameda Creek fish ladder project. Survey studies and mapping of Alameda County floodplains are carried out by the U. S. Geological Survey (USGS) with our assistance and support.

State and Regional Partnerships

We collaborate frequently with a variety of California State departments, including the Department of Fish and Wildlife, Department of Water Resources, State Water Resources Control Board, Wildlife Conservation Board, State Coastal Conservancy, and others to ensure that state laws and mandates are followed for our projects.

The Clean Water Program is a collaborative effort with The San Francisco Bay Regional Water Quality Control Board and 60 other regional agencies who are co-permittees on the joint “Municipal Regional Stormwater Permit” issued under The National Pollutant Discharge Elimination System (NPDES).

Local Partnerships

The District collaborates closely with cities and agencies in Alameda County, community groups, and environmental organizations in areas where our facilities are located.

We frequently partner with the Cities of Emeryville, Fremont, Hayward, Newark, Oakland, San Leandro, and Union City, as well as with municipal groups in unincorporated areas of Western Alameda County, such as Castro Valley, San Lorenzo, and Ashland/Cherryland.

We also work closely with parks and recreational agencies such as the East Bay Regional Park District, Hayward Area Recreation and Park District, and Bay Area Ridge Trail Council to enhance the public’s enjoyment of the County’s creeks.

Environmental and Community Groups

Community groups that conserve creeks and wildlife habitat also participate with the District to improve our creeks:

Other Water Districts

Part of the District’s charter as a water conservation agency is to ensure the beneficial use of water resources in Alameda County – so that water is not degraded or wasted. To support this goal, we collaborate with other local water agencies, including:
