Between 1960 and 1970 divisions of Cheyenne Mountain, Elmere, Black Forest-Peyton, Fountain, Pikes Peak and Monument were annexed into Colorado Springs, resulting in an increased population of 37,500 by 1970. Broadmoor and Skyway were annexed, without a vote of its residents, before the state's Poundstone Amendment (1974) was enacted. Briargate was annexed in 1982.
