The following zoning districts are hereby established for the purpose of promoting the health, safety, morals, and general welfare of the community:
A. Agriculture Districts: (1974 Code § 4-601)
1. AG-20 Agricultural District: Parcels of land which are twenty (20) acres or more and located within the city area of impact shall be subject to zoning laws as provided in the impact area agreement with Twin Falls County. Parcels of land less than twenty (20) acres or parcels used for other than agricultural purposes and located within the city area of impact shall be under the jurisdiction of city zoning laws. AG-20 land may not be subdivided nor split into parcels of land smaller than twenty (20) acres without prior written approval of the city. The meaning of "agricultural land" is found in the definitions in section 9-2-3 of this title. (Ord. 929, 5-14-2007)
2. AG-R5 Agricultural-Residential Five Acre District: To provide for the transition of agricultural land no longer used for extensive agricultural purposes into residential areas, while preserving agricultural uses compatible with residential development, gross density will not exceed one single-family dwelling unit per five (5) acres. This district also is established to control the infiltration of urban development into agricultural areas which will adversely affect agriculture and to provide a district, the boundary of which will provide the transition between rural and urban. (1974 Code § 4-601)
a. Animals: Animals may be kept on pasture only. The total number of animals (other than their young under the age of 6 months) allowed on a lot or parcel shall be limited to the square footage of the lot excluding roads, buildings, yard, etc. (see definitions) divided by the total minimum area required for each animal as follows: 1) horse, mule or cow, forty thousand (40,000) square feet of area per animal; 2) llama, alpaca, emu, goat or sheep, ten thousand (10,000) square feet of area per animal. (1974 Code § 4-601; amd. 2010 Code)
b. Enclosures: Any building or enclosure in which animals or fowl, except domestic pets, of not more than four (4), are contained, shall be a distance of at least fifty feet (50') from any lot in any R-1, R-4, R-6 and R-16, B-2 or B-3 districts or from any school or institution for human care.
B. Residential Districts: To provide regulations and districts for various residential neighborhoods, density in an R district shall be determined by the minimum lot sizes contained in chapter 9 of this title. Centralized water and sewer facilities are required in all districts exceeding one dwelling unit per acre. Centralized water, sewer facilities and annexation may be required in R-1 districts.
1. R-1: This district is intended to permit the establishment of estate lot density single-family dwellings.
2. R-4: This district is intended to permit the establishment of low density single-family and multi-family dwellings and to protect the integrity of residential areas by prohibiting the intrusion of incompatible nonresidential uses.
3. R-6: This district is intended to permit the establishment of medium density single-family dwellings and multi-family dwellings.
4. R-16: This district is intended to permit the establishment of medium high density, single-family attached, and multi-family dwellings at a density not exceeding sixteen (16) dwelling units per acre. All such districts must have direct access to a transportation arterial or collector street. The city may require that such developments require the developer to provide neighborhood park or open area.
5. R-P: The residential professional district provides for a low density mixture of residential land uses with light commercial land uses in possible close proximity to adjacent residential districts. The light commercial uses allowed in this district are selected for their compatibility with residential uses. Such a district is typically appropriate along thoroughfares.
C. Business/Commercial Districts: Centralized water and sewer facilities are required in all business/commercial districts.
1. B-1 Central Business District: The B-1 central business district is intended to accommodate and encourage further expansion and renewal in the historical core business area of the community. A variety of business, public, quasi-public, cultural, residential and other related uses are encouraged. The greatest possible concentration of retail sales and business will occur in this district.
2. B-2: The neighborhood business district is intended to create, preserve and enhance areas of retail establishments serving frequently recurring needs in convenient locations, and is typically appropriate to small shopping clusters or integrated shopping centers located nearby or within residential neighborhoods.
3. B-3: The community business district is intended to create, preserve and enhance areas with a wide range of retail sales and service establishments serving both long and short term needs in compact locations typically appropriate to commercial clusters near intersections of major thoroughfares. This district also includes some development which does not strictly fit the description of this chapter but also does not merit a zoning district.
D. Industrial Districts: Centralized water and sewer facilities are required for all industrial districts, unless waived by a conditional use permit.
1. I-1 Light Industrial: The purpose of the I-1 light industrial district is to provide for light industrial development and to encourage the development of manufacturing and wholesale establishments which are clean, quiet and relatively free of hazardous or objectionable elements, such as noise, odor, dust, smoke or glare and that are operated entirely or almost entirely within enclosed structures; to delineate areas best suited for industrial development because of location, topography, existing facilities and relationship to other land uses. Uses incompatible with light industry are not permitted and strip development is prohibited.
2. I-2 Heavy Industrial: The purpose of the I-2 heavy industrial district is intended to create, preserve and enhance areas containing manufacturing or related establishments which are potentially incompatible with most other establishments, and is typically appropriate to areas which are most distant from residential areas and which have good rail or highway access.
E. District Review Areas:
1. FP Floodplain Overlay District: The purpose of the FP district is to guide development in the flood prone areas of any watercourse that is consistent with the requirements for the conveyance of flood flows, and to minimize the expense and inconveniences to the individual property owners and the general public through flooding. Uses permitted in this district are generally associated with open space, recreational and agricultural land uses and shall not hinder the movement of the floodwaters. (The FP district is superimposed over the other districts.)
F. Airport Zone:
1. AZ airport zone shall be that land, the boundaries of which are described in section 6-4-1 of this code.
2. It is intended that all lands within the airport zone or district shall be primarily available for municipal airport purposes. Excepting other nonconforming uses or buildings now conducted or located on the property within the airport district, all such land shall be used or occupied and any buildings, structure or improvement thereon shall only be used, occupied, placed, replaced, erected, reerected, constructed, reconstructed, altered, extended, enlarged, modified, removed or moved upon obtaining from the planning and zoning commission for the city, a conditional use permit.
3. Except as modified herein, all provisions of this title shall apply to those lands located within the airport zoning district.
4. The administration of this title, as well as the provisions herein as concerns those lands located within the airport zoning district shall be vested with the planning and zoning commission of the city. (1974 Code § 4-601)
G. Public Use Areas:
1. Public use areas are areas designated for use by the public, they shall have no zoning designation.
2. Public use areas shall be shown as such in the city zoning map and related records. (Ord. 960, 6-11-2012)
A. Map Adopted: The districts established in section 9-6-1 of this chapter are shown on the official zoning map, as now existing or as may hereafter be amended, together with all explanatory matter thereon, are hereby incorporated into this title as if set forth in full within this chapter.
B. Boundaries Of Districts: Where uncertainty exists with respect to the boundaries of any of the zoning districts as shown on the official zoning map, the following shall apply:
1. Where district boundaries are indicated as approximately following the centerline of street lines, highway right of way lines, streams, lakes or other bodies of water, the centerline shall be construed to be such boundary;
2. Where district boundaries are so indicated that they approximately follow the lot lines, such lot lines shall be construed to be said boundaries;
3. 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 zoning map. If no distance is given, such dimensions shall be determined by the use of the scale shown on the official zoning map; and
4. 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. (1974 Code § 4-701)
C. Compliance With Zoning District Regulations: The regulations for each district set forth by this title shall be minimum regulations and shall apply uniformly to each class or kind of structure or land. (1974 Code § 4-702)
D. Official Schedule Of District Regulations Adopted:
1. District regulations shall be as set forth in the zoning schedule of land use control, and zoning schedule of bulk and coverage controls, and performance standards for district uses of this title.
2. The districts of the city are divided into four (4) land use groups: agricultural, residential, business/commercial and industrial. When several combined land uses exist, or are proposed, the most intensive land use shall be considered as the primary activity. (1974 Code § 4-703)
E. Uses Not Specifically Permitted Or Listed In Districts: When a use is not specifically listed as a permitted use, such use shall be hereby expressly prohibited unless by application and authorization (as provided for under conditional use) it is determined that said use is similar to and compatible with listed permitted uses. Such uses may then be permitted as conditional uses. (1974 Code § 4-704)
