The municipality of Broomfield was incorporated in 1961 in the southeastern corner of Boulder County. Over the next three decades, the city grew through annexations, many of which crossed the county line into three adjacent counties: Adams, Jefferson and Weld. In the 1990s, city leaders began to push for the creation of a separate county to avoid the inefficiencies of dealing with four separate court districts, four different county seats (each a considerable distance away), and four separate county sales tax bases. Broomfield reasoned that it could provide services more responsively under its own county government, and sought an amendment to the Colorado State Constitution to create a new county. The amendment passed in 1998, after which a three-year transition period followed. On November 15, 2001, Broomfield County became the 64th county of Colorado.
