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. Longmont, CO Real Estate.
