Responsibilities include development and administration of Teton County’s Subdivision Regulations, Hazard Mitigation Plan, enforcement of Floodplain Regulations, and overall land use management for the County in accordance with the Growth Policy. Our responsibilities also include facilitating communication between the landowners/developers and Stahly Engineering for the review of certificates of survey prior to filing with the County Clerk and Recorder for clerical errors and omissions and to insure exempt divisions of land are in compliance with the provisions outlined in the Montana Subdivision and Planning Act. Our office also issues new rural addresses and develops project maps for other departments. All 911 address data is created, edited and disbursed to the appropriate agencies as necessary to facilitate emergency response. This office issues floodplain permits and letters to interested parties regarding the absence of zoning in the county, when requested.


Teton County DRAFT Growth Policy

Teton County Commissioners have authorized the Teton County Planning Board to develop a Growth Policy on behalf of the County, including considerations for the incorporated towns within the County. The City of Choteau currently utilizes a separate Growth Policy.

A Growth Policy is a means of proactively preparing for change affected by growth or lack of growth. It is a community’s development plan. It evaluates existing community conditions and sets goals for housing, land use, economic development, local services, public safety, natural resources, transportation, and other unique characteristics and features of the community.

Citizens of Teton County are encouraged to get involved by reviewing the DRAFT Growth Policy now available on the project website at or in hard copy at the Teton County Planning Office. You may also leave comments on the website or mail them: Attention Teton County Planner, PO Box 610, Choteau, MT 59422.

Anyone who would like more information can contact Brian Colesworthy, Teton County Planner, (406) 466-3130 or Robie Culver, Stahly Engineering & Associates, (406) 442-8594.
