The purpose of establishing the 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.

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

1. Grandfather Rule: The grandfather rule will apply to all existing lands and businesses.
2. Agricultural Land: Agricultural land should be preserved for agricultural use. The area of city impact shall not be construed as authorizing restrictions on farm practices, including, but not limited to: use and application 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. Replatting; Public Services: 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: Strip development along major arterials should be considered by the planning and zoning commission.
5. Water And Sewer: 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: Traffic circulation and access to existing primary and secondary arterials must be adequate.

The following criteria should be considered in defining the area of city impact:

1. Trade Area: The area related to economic influences which could have an impact on the city; i.e., shopping facilities, employment and patterns of growth;
2. Geographic Factors: Topographical features which influence the direction of development; i.e., waterways, soil suitability and topography suitable for development of streets and extension of public services; and
3. Areas Considered For Annexation: Areas the city could reasonably be expected to provide services to within five (5) to ten (10) years, i.e., police, fire, central water or sewer facilities.

The following area of city impact zoning districts are hereby established. For interpretation of this article, the zoning districts have been formulated to realize the general purpose as set forth in this title and to conform with the comprehensive plan and its stated goals and objectives. In addition, the specific purpose of each zoning district shall be as stated.

1. A Agricultural District: The purpose of the A district is to permit current agricultural, large lot rural residential and other types of open land uses to be maintained, and to protect agricultural land from spasmodic, disorderly and indiscriminate development. This district is also established to control the infiltration of urban type development, which could adversely affect agricultural operations, until such time as property owners desire such development.
2. R-A Residential-Agricultural District: The purpose of the R-A district is to create, protect and maintain a living environment composed of single-family, detached dwellings on lots of reasonable size to be able to maintain the minimum distances required for setback, drainfields, canals and property lines in areas now so developed or to be developed.
3. HC Highway Commercial District: The purpose of the HC district is to provide for the location and development of businesses and service establishments which are incompatible with other districts, in that they involve enterprises which depend primarily on motorized vehicular traffic and require outside activities, relatively large lot sizes and easy highway access. These districts are normally located along highways leading into the city and are characterized by buildings set well back from the right of way.
4. M Manufacturing District: The purpose of the M district is to encourage manufacturing and wholesaling activities in an area which will impact as little as possible on the other districts within the city and area of city impact. As this type of enterprise normally needs heavy truck or railroad access, it is normally located along highways leading into the city or along railways. This district should be kept free from residential and retail commercial activities.
5. RR Rural Ranchette District: The purpose of establishing the Rural Ranchette Zone is to promote and maintain a single-family residential neighborhood that protects animal rights as part of allowed uses. The purpose is to preserve areas of land where small acreage including domestic farm animals may be kept within the city limits and the impact area. The zone also includes residential uses for Accessory Dwelling Units (ADUs), and for handicapped and elderly persons up to eight (8) as referenced by Idaho Code Section 67-6531.
   

Where uncertainty exists with respect to the boundaries of any of the area of city impact use districts as shown on the official area of impact map, the following shall apply:

1. Centerlines: Where district boundaries are indicated as approximately following the centerline of streets, highway right of way, streams, canals or other bodies of water, the centerline shall be construed to be such boundary;
2. Lot Lines: Where district boundaries are indicated as approximately following lot lines, such lot lines shall be construed to be said boundaries;
3. Parallel: Where district boundaries are so indicated that they are approximately parallel to the centerlines or street lines of streets or the centerlines or right of way lines of highways, such district boundaries shall be construed as being parallel thereto and at such distance therefrom as indicated on the official area of impact map; and
4. Railroad Line: Where the boundary of a district follows a railroad line, such boundary shall be deemed to be located in the middle of the main tracks of said railroad line.

The arterials of the city and impact area are as listed: Moody Road, Digger Drive (2000 East), 3rd South, 1000 East, Highway 33, 3rd North and Highway 20 (191).

The regulations for each district as set forth by this title shall be minimum requirements and shall apply uniformly to each class or kind of structure or land, specifically:

1. District Regulations: No building, structure or land shall be used or occupied and no building or structure or part thereof shall be erected, constructed, reconstructed, moved or structurally altered except in conformity with all the regulations herein specified for the district in which it is located and until the proper permits have been obtained;
2. Buildings And Structures: No building or other structure shall be erected or altered to:
   1. Provide for greater height or bulk;

   4. Have a narrower or smaller rear yard, front yard or other open spaces; Other than herein required or in any other manner contrary to the provisions of this title; and
3. Yard Or Lot Reduction: No yard or lot existing at the time of passage of the ordinance codified herein shall be reduced in dimension or area below the minimum requirements set forth herein. Yards or lots created after the effective date hereof shall meet at least the minimum requirements set forth herein.

The administrator shall interpret the appropriate district for land use not specifically listed on the official schedule of area of impact district regulations (see SCC 9-8B-3) by determining the district in which similar uses are permitted. When several combined land uses exist or are proposed, the most intensive land use shall be considered as the primary activity.

9. Public, Public Utility, Church And School Buildings: Public and public utility buildings, public and private schools and churches may be erected to any height, provided the building is set back from required lot lines at least one foot (1') for each additional foot of building height above the maximum height permitted in the district in which the building is located.

1. Multi-Family Dwellings: Multi-family dwellings shall be considered as one building for the purpose of determining front, side and rear setbacks. The entire group as a unit shall require one front, one rear and two (2) side setbacks as specified in this section.
