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 in Alhambra, California.〔"(Contact Public Works )." Los Angeles County Department of Public Works. Retrieved on September 27, 2009.〕 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. The Department of Public Works is the largest municipal public works agency in the country, employs over 3,500 people, and has a budget in excess of one billion dollars. 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. 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.〔Amy Pyle and Leslie Berger, (Boy's Death Prompts Calls for Changes ), ''Los Angeles Times'', February 15, 1992〕 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. The first director was Thomas A. Tidemanson, P.E. After his retirement, the Alhambra, California headquarters building was named for him.〔(Los Angeles County Public Works Director Will Retire After 38 Years ), ''Los Angeles Times'', January 06, 1994〕 Gail Farber became the Director of Public Works on December 1, 2008 at an annual salary of $230,000. Farber was previously the Director of Public Works for the City of Orange.〔(Public Works Director Named ), ''Dept. of Public Works Press Releases'', November 12, 2008〕 ==Recent Public Works accomplishments== Opening of the East Los Angeles County Hall Building - On January 31, 2007, Los Angeles County Supervisor Gloria Molina (1st District) dedicated East L.A.’s own “City Hall.” As a thriving unincorporated community, East Los Angeles has long awaited for its own full service civic facility. The new County Hall will serve as East L.A.’s “City Hall”— bringing County services closer to the community. The County Hall is a significant milestone of the ELA Civic Center project, initiated in 1999, to establish a central location where the local community can easily access County services. County Hall services include the First District Community Office, the Public Works Building and Safety Counter, the Department of Consumer Affairs, the Department of Parks and Recreation, the Department of Regional Planning, and other permitting agencies such as the Health Department and the Fire Department. Los Angeles County Flood Control District Opens Historic LA River Wetlands Project – On May 8, 2008, County of Los Angeles Supervisor Don Knabe (4th District) was joined by City of Long Beach Mayor Bob Foster to open the Dominguez Gap Wetlands in Long Beach. The $7 million treatment wetlands and spreading grounds project is the latest in a series of regional, multi-benefit projects implemented by the Los Angeles County Flood Control District, including the Sun Valley Park and Tuxford Green projects in the Sun Valley Watershed and the Tujunga Wash Greenway and River Restoration project in the San Fernando Valley’s Valley Glen community.〔(Wetlands renovation aims to reduce pollution from stormwater in the Los Angeles River ) ''American City & County'', April 1, 2009〕 The wetlands project is one of the top five demonstration projects of the Los Angeles River Master Plan. The wetlands project is the first of its kind in the Los Angeles County region. It maintains the integrity of flood protection along the urban lower reaches of the river, while introducing new water quality elements, groundwater recharge, restoration of native habitat, pedestrian and equestrian trails, environmental education, and river bike trail enhancements. The project encompasses extensive renovation of two preexisting Flood Control District spreading grounds, located along both sides of the Los Angeles River between Del Amo Blvd. and the 405 Freeway. State Official Award $25 Million to Southland Water Projects – On July 25, 2008, Lester Snow, director of the State Department of Water Resources, presented a $25 million mock-check to County of Los Angeles Supervisor Yvonne B. Burke and local officials from water supply and water treatment agencies, municipalities, and non-governmental organizations throughout the greater Los Angeles county region. The $25 million will help fund 14 water-related projects dispersed throughout Los Angeles County.
