The Department of Public Works plans, designs,constructs, operates, and maintains facilities and equipment that are safe and accessible to the clients of County agencies, the general public and County employees. The Department advises the Board of Supervisors on all public works issues, including rates and charges for services that are fair to both the users and service providers. Public Works has a budget of approximately $200 million and is comprised of over 300 employees in four divisions: Administrative Services and Airports, Engineering and Resource Protection, Facility Services, and Road Services. Most of the Public Works budget is funded from sources other than the County’s general fund. The budget includes federal and state funds earmarked for aviation and transportation, landfill franchise fees for waste management programs, gas taxes to maintain 320 miles of County roads, and property taxes and service charges to provide various services to the 46 special districts governed by the Board of Supervisors and administered by the Department.
