Two years before Montana was granted statehood, T.E. Collins proposed the creation of Cascade County. Collins, a representative at the first legislative assembly held in Virginia City, proposed a bill to the Territorial Congress which would designate a new territorial county. The year was 1887 and Montana was still a territory that President Abraham Lincoln had approved of creating in 1864. Collins' bill proposed taking land from Lewis and Clark, Meagher, and Chouteau counties in order to create this new territorial county. The bill was approved, after many debates, and Cascade County was created. Two years later, in 1889, Montana was granted statehood.
One could argue that the planning was done by Collins and others, in order to create Cascade County, loosely created the first Cascade County Planning Department. Officially, Cascade County Commissioners created the Cascade County Planning Board on November 19, 1973. The first meeting of the Cascade County Planning Board was held on January 22, 1974.
