Who Are We?

Alameda County is the seventh largest county in California, with an estimated 141,898 residents within its unincorporated areas (including the urban communities and most of the rural outlying areas of the eastern portion of the county) and a total population of 1,510,210. (U.S. Census, 2015).  

The Public Works Agency serves the unincorporated areas of Alameda County, including Castro Valley, Sunol, San Lorenzo, Ashland, Cherryland, Fairview, and unincorporated parts of San Leandro, Hayward, and Livermore.  

We design, build and maintain the public infrastructure, including streets, sidewalks, bike lanes, creeks, flood control facilities and storm drains.  Along the unincorporated roadways in Alameda County, we sweep public streets, landscape the public right-of-way, trim trees, and remove graffiti.  We oversee the installation and operation of traffic signals, street lights, roadway signage, roadway pavement markings and paint.  We also work with neighborhood associations to resolve speeding, parking and traffic problems. 

The Agency also performs the engineering review of private development and issuance of building permits, right of way encroachment permits, and well-drilling permits.  The Public Works Agency also facilitates a variety of community programs including beautification, cleanup projects, graffiti abatement, community celebrations, and biking/walking safety and promotion programs.  

The Agency administers the Alameda County Flood Control and Water Conservation District, a separately chartered organization that serves the entire county.  The Alameda County Flood Control and Water Conservation District helps protect Alameda County residents and property from flooding while preserving the natural environment.  The District is the devoted steward of a valuable resource—a vast flood control infrastructure including channels, pump stations and other facilities.  The District works specifically to protect county citizens from flooding while preserving the natural environment. 

As a first responder agency, the Public Works also maintains a 24-hour Dispatch Center and an on-call Department Operations Center during hazardous weather events or other emergency events. We provide emergency response services to situations or concerns involving County maintained roads or flood control channels.
