The Los Angeles County Department of Public Works (LACDPW) is responsible for the construction and operation of Los Angeles County's roads, building safety, sewerage, and flood control. DPW also operates traffic signals and intelligent transportation systems, drinking water systems in certain communities, operates five airports, paratransit and fixed route public transport, administers various environment programs, issues various permits for activities in the public roadway, and has a Department Emergency Operations Center that works in conjunction with the County Emergency Operations Center operated by the Sheriff's Department. The department is headquartered at 900 South Fremont Avenue in Alhambra, California.[3]
Services are provided primarily to the unincorporated county with some services provided to contract cities. Flood control and watershed management services are provided to all of the county except the Antelope Valley.
As part of its flood control and water supply responsibilities, the Department of Public Works has 15 major dams and 27 spreading grounds in the county.[4] Pacoima Dam is one of the largest owned by Public Works and survived the Northridge earthquake in 1994 intact.
Water from the dams is released into flood-control channels and some is diverted into spreading basins where it percolates into the ground and recharges the groundwater. The surface water is not used directly as it requires more cleaning than groundwater. Near the coast, the department has constructed sea water barriers that use injection wells to create a fresh water barrier to prevent salt water intrusion from the ocean into the groundwater.[5]
The DPW is a leader in watershed management. It provides storm drain education programs, publishes and enforces best management practices for activities that may affect the watershed, and manages watersheds to provide a balance between flood control, recreation, and protecting the natural environment.
