Longmont is a Home Rule Municipality in Boulder County and Weld County in the U.S. state of Colorado. Longmont is located northeast of the county seat of Boulder and 33 miles (53 km) north-northwest of the Colorado State Capitol in Denver.
Longmont was founded in 1871 by a group of people from Chicago, Illinois. Originally called the Chicago-Colorado Colony, the men sold memberships in the town and with the proceeds purchased the land necessary for the town hall. As the first planned community in Boulder County, the city streets were laid out in a grid plan in a square mile. The city began to flourish as an agricultural community after the building of the Colorado Central Railroad line arrived northward from Boulder in 1877. During the 1940s, Longmont began to grow beyond these original limits.
During the 1960s the federal government built an air traffic control center in Longmont, and IBM built a large factory near Longmont. As agriculture waned, more high technology has come to the city, including companies like Seagate and Amgen. In April 2009, the GE Energy Company relocated its control solutions business to the area.
The downtown along Main Street, once nearly dead during the 1980s, has seen a vibrant revival in the 1990s and into the 21st century. During the mid-1990s, the southern edge of Longmont became the location of the first New Urbanist project in Colorado, called Prospect New Town, designed by the architects Andrés Duany and Elizabeth Plater-Zyberk.
The Longmont City Council in May 2013 voted to finance and build out its own municipal gigabit data fiber-optic network to every house and business over a three-year period starting in late 2013.
