Re-Addressing Information
Gallatin County is in the process of evaluating existing road names and address numbers throughout the County.  The Gallatin County Geographic Information Systems (GIS) Mapping and Addressing Department, under the direction of the Gallatin County Commission Resolution 2000-128 and 2002-17, is in the process of re-naming roads where necessary, and re-addressing non-compliant structures to State of Montana Standards and Enhanced 911 National Emergency Numbering Association (NENA) guidelines.  

The major purpose of this change will be to facilitate the easy and rapid location of properties by law enforcement, fire protection services, search and rescue and emergency medical services to protect public health and safety of all persons living, working or visiting in Gallatin County. Your address number must be clearly posted at your driveway, visible from both directions of travel, day or night. It should also be posted on your structure so it is visible at night.  To provide the location of a caller, your telephone number must be linked to a physical address that clearly identifies the location of that telephone. The name, address and phone number of the telephone used to dial 911 will be displayed on a computer screen at the Gallatin County Emergency 911 Center, providing directions to your location.

In an emergency--time is essential, make your structure easy to locate!

Why is my road being changed?
Duplicate road names, and similar sounding names, can cause serious life-threatening delays in response time by emergency service personnel.  Standardization is necessary to reduce the chance that response time for Enhanced 911 calls may be delayed if a location is not readily identifiable by the caller, dispatcher or emergency service personnel. This process will identify and re-name these problem roads.

New roads are normally named by the residents or by the developer of a subdivision. GIS will verify any proposed name and make sure the name is not already in use within Gallatin County or Gallatin County Cities/Towns, and then GIS will approve or deny the request.

Why are some driveways named?
We name private roads that have three or more structures. This provides for additional addresses as property owners develop their land and eliminates confusion with the connecting road numbers. Assigning a name to a private drive does not mean that Gallatin County or the Cities will start maintaining the road or that the mail carrier will deliver mail to the houses on that road. It is still a private road; it just has an official road name to make location by emergency vehicles easier.

Gallatin County does not provide or install road sign(s) on private lanes. At the present time, there is no County ordinance regarding placement of private road signs. This means that placement of road signs on private roads is not required but it is highly recommended. Emergency response teams will be able to function much more effectively if they have road signs to refer to. It will be the responsibility of the resident(s) living on private roads to pay the expense of furnishing and/or replacing road signs. It is strongly recommended that you contact a sign shop that can provide necessary information regarding type, color, letter size, sign materials, post heights and placement.

How are address numbers issued?
In Gallatin County, we use the “Frontage Interval System” of addressing exercising a measured system based on actual road distances to determine your address number. Numbers are assigned at an interval of 1000 per mile; therefore, a structure located one mile down a road would have the address of 1000.  Numbering with this format mentally gives the responder a firm idea how far they must travel to reach your location.  Even numbers are on the South and East sides of the road and odd numbers are on the North and West based on the predominant travel direction of the road. This system is very familiar for emergency responders, postal and delivery services.

How may we assist you?
We realize that a change of address can create an inconvenience and will work with you in whatever capacity we can to make the transition more pleasant.  The GIS Department will provide address change notification to the following:
                

911 Center

Bozeman Daily Chronicle

FedEx/UPS

Gallatin County Sheriff

Republic Waste Systems

AMR Ambulance Service

United States Post Office

Is it possible to change a roadname?
We have developed a procedure where residents may petition to change an already named road through a public hearing.  Using the petition available below, signatures may be obtained from landowners with access off; or address assignment on; or are landowners along the road to be changed.

Landowner signatures are verified with the Clerk and Recorder and the GIS Department will facilitate the required legal notices and present the petition at a public hearing for decision by the County Commission.
