The city is a part of the DenverAuroraLakewood, CO Metropolitan Statistical Area and the Front Range Urban Corridor. It was incorporated in 1961 in the southeastern corner of Boulder County. The name is believed to come from broomcorn grown in the area, a tall sorghum that farmers sold for use as brooms and whisk brooms. In the 1990s, 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 sought an amendment to the Colorado 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, and the most recently created county in Colorado.
