Biohazard Cleanup Near Beacon Point Aurora, CO

Aurora is a home rule city that spans three counties — Arapahoe, Adams, and Douglas — on the eastern side of the Denver metropolitan area.

Aurora is the third-most populous city in Colorado.

The community was platted in 1891 under the name Fletcher, honoring Denver businessman Donald Fletcher.

Fletcher was incorporated as a town on May 5, 1903.

After Donald Fletcher left town following the Silver Crash era and left the community burdened with a large water debt, voters renamed the town Aurora in 1907, taking the name from one of its subdivisions.

Aurora was reincorporated as a city on March 9, 1928.

The 2020 census counted 386,261 residents in Aurora, with 336,035 living in Arapahoe County, 47,720 in Adams County, and 2,506 in Douglas County.

At the 2010 census, Aurora had 121,191 households and 131,040 housing units.

Aurora was the fastest-growing city in the United States in the late 1970s and early 1980s, and it has surpassed neighboring Denver in total land area since the 2000 census.

Lowry Air Force Base opened in 1938 along the Aurora–Denver border and closed in 1994, after which the site was redeveloped as a planned community.
