In the last two decades, its central location among the population centers of northern Colorado, together with its proximity to Interstate 25, have made it the site of rapid urban growth, particularly on the western edge of town, as it grows towards the interchange on I-25. In the 1990s, the town limits were westward into Larimer County. The incorporated town limits west of Interstate 25 are now contiguous with Loveland, and are separated from southeast Fort Collins by the Fossil Creek Open Space public lands of Larimer County acquired through a county-wide vote-approved sales tax.
