The department was formed in 1985 in a consolidation of the county Road Department, the Flood Control District (in charge of dams,
spreading grounds, and channels), and the County Engineer (in charge of building safety, land survey, waterworks). For 25 years, the County Engineer Department was housed in the historic
Higgins Building, a 10-story
Beaux-Arts style commercial building that was designed and built by noted architect Arthur L. Haley and engineer Albert Carey Martin in 1910, at the corner of Second and Main Streets in
Downtown Los Angeles. After "overseeing construction projects large and small from one of the city's strongest buildings, the county determined that the department needed more modern quarters and pulled up stakes in 1977," according to the Los Angeles City Planning Department, which designated the building as the Historic-Cultural Monument #873. In 1977, the County Engineer Department moved to the corner of 5th Street and Vermont Ave., Los Angeles until the merge of the three departments. At that time the department was called the Department of County Engineer-Facilities. In 1988, the department issued a demolition permit to tear down the historic
Golden Gate Theater in
East Los Angeles. Demolition commenced before officials led by then County Supervisor
Ed Edelman halted the work with a stop-work order. Demolition crews had already begun to dismantle the walls when Edelman, then Los Angeles City Councilwoman
Gloria Molina, sheriff's deputies and more than 50 concerned community members showed up at the site to ensure the demolition work was halted. Edelman blamed a "foul-up" in the Public Works Department for issuing the demolition permit and assured the gathered crowd that heads were going to roll and that he would "try and stop this damn demolition before it happens." For years, the Flood Control District and the County Road Department were headquartered in buildings at Alcazar Street in East Los Angeles by the Los Angeles County General Hospital. Major divisions of the Public Works Department were located at various locations in Los Angeles city for a number of years, until the 12-story glass building in
Alhambra, California was purchased and refurbished. This tallest structure in Alhambra was formerly the western headquarters of
Sears, Roebuck and Company, where some fixture units still bear the label "Sears". The steel frames were strengthened in 2006 after it was learned from the
Northridge earthquake that the welded joints were not adequate to withstand a major earthquake. == Former directors ==
