The County of Los Angeles Department of Public Works was formed in January 1985, consolidating the former County Road Department, the County Engineer Department and the County Flood Control District.

The Department is responsible for the design, construction, operation, and maintenance of roads, traffic signals, bridges, airports, sewers, flood control, water supply, water quality, and water conservation facilities. The Department monitors and controls traffic signals countywide from its Traffic Management Center in Alhambra and, as a County first responder agency, maintains a 24-hour Dispatch Center and on-call Department Emergency Operations Center to respond to daily incidents, local emergencies and major disasters The Department also provides project management services for the design and construction of the County Capital Projects Program and provides a leadership role in the countywide transportation system, traffic mitigation efforts, and solid and hazardous waste management services.

The Department's diverse operations are defined within six core service areas: Transportation, Water Resources, Waste Management, Public Buildings Development Services, and Emergency Management. Its annual operating budget of $2.3 billion is funded by restricted revenues, such as gas excise and sales tax, benefit assessment, water and sewer sales, user fees, and Contract Cities revenues.
