Broomfield is a consolidated city and county located in the U.S. state of Colorado.[1] Broomfield has a consolidated government which operates under Article XX, Sections 10–13 of the Constitution of the State of Colorado. The Broomfield population was 74,112 at the 2020 United States Census,[5] making it the 15th most populous municipality and the 12th most populous county in Colorado. Broomfield is a part of the Denver–Aurora–Lakewood, CO Metropolitan Statistical Area and the Front Range Urban Corridor.


Several railroads figure in the development of this area. The Colorado Central Railroad built a narrow-gauge line from Golden in 1873, the Denver, Utah and Pacific Railroad arrived in 1881, and the Denver, Marshall and Boulder Railway built a line through what is now Broomfield in 1886. The Denver, Utah and Pacific was widened to standard gauge in 1889. One of the early names for the area was Zang's Spur, after the railroad spur serving Adolph Zang's grain fields.[8]

The municipality of Broomfield was incorporated in 1961 in the southeastern corner of Boulder County. Researchers speculate the city was named for the sorghum grown in the area, also known as broomcorn, which farmers sold to manufacturers of brooms and whisk brooms.[9]

In the 1990s, after three decades of annexations, Broomfield stretched across Adams, Boulder, Jefferson, and Weld counties, city leaders felt increasing chagrin with the need to deal with four separate court districts, four different county seats, and four separate county sales tax bases. They began pushing to make Broomfield a consolidated city-county similar to Denver, reasoning that they could provide services more responsively if it had its own county government.

The city sought an amendment to the state constitution to create a new county. The amendment was passed in 1998, after which a three-year transition period followed.

On November 15, 2001, Broomfield County became the 64th and smallest county of Colorado. It is the newest county in Colorado (and in the entire United States, if county equivalents are not included.)[10]

On February 20, 2021, United Airlines Flight 328 from Denver to Honolulu experienced an engine failure after takeoff from Denver International Airport and debris from the engine landed in parts of Broomfield. Multiple homes were damaged, but no injuries were reported, and the plane landed safely at DIA.[11]


Broomfield is located midway between downtown Denver and Boulder along U.S. Route 36.

The elevation in Broomfield ranges from 5,096 to 5,856 feet (1,553 to 1,785 m).[12] At the 2020 United States Census, Broomfield had a total area of 21,471 acres (86.890 km2), including 371 acres (1.503 km2) of water.[5] It is the smallest county by area in Colorado and the 5th smallest in the United States. Broomfield is the second most densely populated county in Colorado behind Denver.[13]


Rocky Mountain Metropolitan Airport formerly known as Jefferson County (Jeffco) Airport is located in Broomfield.

Council members

Sheriff and county commissioners

Broomfield operates as a consolidated city-county. The city council acts simultaneously as the board of county commissioners, and the police chief is simultaneously the county sheriff. The Broomfield Police Department performs all of the duties that would normally be performed by a county sheriff's office, including operating the county jail (detention center), providing security and bailiff services for the Broomfield Municipal, County, and District Courts and the Combined Courts Building, and providing civil process in the county. The police chief can be hired or fired at will by the city council, which makes Broomfield's sheriff, along with Denver's, the only non-elected sheriffs in the state.
