Broomfield is both a city and a county at the same time

Broomfield is one of only two places in Colorado that is a combined city and county, formed when the city's land was pulled out of four other counties.

If you live in Broomfield, your city and your county are the same government. That is unusual in Colorado. Most places sit inside a county that is separate from the town. Broomfield does not.

For years, the City of Broomfield was a single town whose streets and neighborhoods spilled across the lines of four different counties. A home on one block answered to one county; a home a few streets over answered to another. That split made simple things harder, from voting to taxes to who plowed which road.

Voters approved a change to the state constitution to fix it. The city’s land was detached from those four counties and joined into one combined unit: the City and County of Broomfield. After that, one government handled both the city work and the county work for the same piece of ground.

Why this still matters today: in Broomfield you do not have a separate county courthouse in another town making decisions about your property. The same elected body and staff handle local services and county duties together. It is a tidy setup, and it explains why Broomfield feels different from its neighbors on a map.

To read how the consolidation happened and how the government is organized, see the City and County of Broomfield’s official site and the state’s local-government office.
