The purpose of establishing the Teton city impact area is to identify a logical fringe area in the unincorporated territory surrounding the city within which there is potential for development or changes in land use that could have an impact on the area and the city; could impact the timely or economical provision of public services such as water supply, sewage collection and treatment and community service facilities; or could impact the quality of life within the city. (Ord. 304, 1-7-2005)

The Teton city impact area shall be determined by the county commissioners and the Teton city council. (Ord. 304, 1-7-2005)

The following factors shall be addressed by the commissioners and the council when a proposed development or change in land use within the area of city impact:

1. The grandfather rule will apply to all existing lands and businesses.
2. Agricultural land should be preserved for agriculture use. The area of city impact shall not be construed as authorizing restrictions on farm practices, including, but not limited to: use and applications of fertilizers, pesticides, herbicides and fungicides (which are allowed to be used legally); soil tillage and conditioning; use of machinery for tillage, conditioning, harvesting, application of chemical inputs and transport; the use of aircraft and its resulting noise and other impacts; and the production of livestock and poultry.
3. Any development or change in land use should be laid out in a manner which will permit replatting and the provision of public services when warranted.
4. Strip development along major arterials should be considered by the commission.
5. Before additional development occurs within the area of impact, the availability of water and adequacy of centralized sewer or individual on site sewage disposal systems must be established in compliance with health department codes.
6. Traffic circulation and access to existing primary and secondary arterials must be adequate. (Ord. 304, 1-7-2005)
