Adams County, Colorado

adams county

Adams County was created by the Colorado legislature on April 15, 1901 out of the northern portions of Arapahoe County. The eastern portions of the county were realigned to become part of Washington and Yuma counties on May 12, 1903. Following a 1989 vote, 53 square miles of the county was transferred to the City and County of Denver for the purpose of constructing Denver International Airport, leaving the western portion of the county as two oddly-shaped peninsulas. Adams lost additional territory in its northwest corner on November 15, 2001, when the City and County of Broomfield was created.

It is named for Alva Adams, a former Governor of Colorado. The county seat is Brighton; the largest city is Aurora.
