Readdressing Project


The GIS Department works to create a database of all address points within Coconino County in order to provide the information needed for the Enhanced Emergency 911 system. This allows Coconino County in collaboration with its partner agencies to provide the needed information for appropriate emergency and non-emergency response, and support the needs of the 911 dispatch center.

Major Objectives: 

  • To allow faster emergency response by fire, police, rescue, medical and any other emergency services.
  • To establish a property location that will serve as Emergency 911 locator.
  • To assist in the proper delivery of mail, utility and other services.
  • To provide property owners and the County with a convenient, accurate and systematic way of identifying property.
  • To name new streets and rename old streets with conflicting or duplicate names in order to provide efficient emergency services.
  • To support the County move to the Enhanced 911 system.
