About Us

Who We Are

The Alameda County Public Works Agency (ACPWA) is responsible for the management and operations of infrastructure including streets, bridges and flood control facilities, such as pump stations and stormwater conveyance infrastructure.  ACPWA manages the planning, design, construction and maintenance of these facilities.  Additionally, the Agency facilitates private development through the review and issuance of permits and inspection of private developments.

With the exception of Flood Control services that are provided throughout the County, ACPWA primarily serves the unincorporated areas of Alameda County. The Agency is a multi-disciplinary, high performing organization that fulfills its mission through its skilled and dedicated workforce organized in four distinct structures: Engineering Department; Construction and Development Department; Maintenance and Operations Department, and Administration/Management Services Department.  Detailed areas of service, are listed below.
