Before incorporation in 1969, Lakewood was an urban sprawl with policing provided by the Jefferson County Sheriff, a volunteer fire service, and with few street lights and sidewalks. Many of the older residents appreciated the absence of municipal taxes. The City of Lakewood was incorporated in 1969. At the time of incorporation the city population was already over 90,000, making Lakewood one of the largest cities, at the time of original incorporation, in the history of the United States.
The urban/suburban development of the community known as Lakewood was begun in 1889 by Charles Welch and W.A.H. Loveland, who platted a 13-block area along Colfax Avenue west of Denver in eastern Jefferson County. Loveland, the former president of the Colorado Central Railroad, retired to the new community of Lakewood after many years of living in nearby Golden.
Lakewood also houses the prestigious Lakewood High School, ranked number one in the state by Newsweek, and the only International Baccalaureate school in Jefferson County. Lakewood is also home to Colorado Christian University.
