The addressing of properties and buildings is one of the most critical components of effective emergency response. LFRA, along with its partner municipalities, ensures that approved street names and building address numerals are consistent with standards and easy to recognize and use.
Proposed street names and numerals typically are reviewed and approved during the Planning process. In addition to LFRA and the municipality, addresses are reviewed by the Larimer Emergency Telephone Authority, which is the governing authority for 9-1-1 in Larimer County. LETA provides oversight to 9-1-1, and the equipment and the programs funded by LETA. Larimer County has five 9-1-1 call centers, 25 government entities, one State University and one National Park.
