Los Angeles County Public Works 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. Its diverse operations fall within six core service areas: Transportation, Water Resources, Environmental Services, Public Buildings, Development Services, and Emergency Management.

The Department's responsibilities include monitoring and controlling traffic signals countywide from its Traffic Management Center in Alhambra. Public Works also maintains a 24-hour Dispatch Center and an on-call Department Emergency Operations Center. In addition, it provides project management services for the design and construction of the County Capital Projects Program and plays a leadership role in the countywide transportation system, traffic mitigation efforts, and solid and hazardous waste management. The Department also manages about 232 active capital projects with a total construction value of over $847 million.

Its annual budget of $3.17 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.

The Department's workforce is made up of nearly 4,000 employees in more than 500 job classifications including professional, technical, clerical and skilled crafts.
