The Street Inventory System (SIS) contains the names of all streets in Larimer County and its municipalities.
The purpose of this system is to provide a central location for all names, prevent duplicate street names in the future, and
allow only approved suffixes.
This system is a joint project of Larimer County, Larimer Emergency Telephone Authority (LETA), and the cities
of Fort Collins, Loveland, Estes Park, Berthoud, Wellington, Timnath, Johnstown, and Windsor. See
