Boulder City Incorporated
The Boulder City Town Company had been formed by a settler, A.A. Brookfield, in February 1859. At that time, the settlement was part of the Nebraska Territory. In 1861, a federal bill established the Territory of Colorado. The town was initially incorporated in November 1871 in violation of the Treaty of Fort Laramie. In 1880, the town passes the 3,000 population mark, making it eligible for incorporation, and in 1882 Boulder is officially incorporated as a 2nd class town.
