In addition to the general purposes identified in MCC 10.02, the various zoning districts each serve a more specific individual purpose, as described below. (Ord. 040202, 4-2-2002)

The R (residential) zoning districts are created to provide for a range of densities which will reflect the diverse needs and desires of the people of the city. These districts shall also allow for other compatible uses which may complement the primarily residential function of the district, under certain conditions. Basic urban services and utilities should be available in all of these zones.

1. R-R Zone: The R-R zone is intended to provide area for very low density, suburban type uses. It may, provided adequate lot area exists, include farm animals.
   
2. R-1 Zones: The R-1 zones are intended to provide areas for single-family attached and detached dwellings of a low density. (Ord. 040202, 4-2-2002)
   1. The R-1-8 zone is not an available zoning designation for purposes of zoning applications filed after July 1, 2006. (Ord. 06-10, 6-27-2006)
      
3. R-MH Zone: The R-MH zone is intended to provide areas for mobile home and travel trailer parks to develop at a low density. Because of the required size of these developments, they should be located adjacent to an arterial or collector street.
4. R-M Zones: The R-M zones are intended to provide areas for multi-family attached dwellings at medium to high-medium densities. Single-family dwellings are also allowed in these zones. These districts shall be located adjacent arterial streets and, in some circumstances, major collector streets. (Ord. 040202, 4-2-2002)
   
5. MRO Zone: The MRO zone is intended to provide a variety of home choices and sizes. See Chapter 10.15 - Mixed Residential Overlay (MRO) Zone.

The C (commercial) zoning districts are intended to provide area or commercial uses based on considerations such as: the intensity of the use, goods and services provided, and the market area. In all cases, these districts shall abut an arterial or major collector street.

1. C-G General Commercial: The C-G general commercial district is intended to provide commercial services to an area of limited size, for basic trade and personal services which occur regularly or frequently. The major market area for this district is the adjacent residential areas. This type of district should be located at the intersection of arterial or collector streets. It services both pedestrian and vehicular traffic.
   
2. C-C Central Commercial: The C-C central commercial district is to provide a range of commercial uses greater than that of the C-G, but at a lower intensity than a highway commercial zone. The basic market for this district is vehicular oriented and the major market area is the city. This type of district is best located at the intersection of or adjacent to arterial streets.
   
3. C-H Highway: The C-H highway commercial district is intended to provide area abutting major arterial streets or freeways for a full range of commercial and professional uses; however, the primary focus should be on uses which require large retail display or merchandise storage areas and serve a regional market. (Ord. 040202, 4-2-2002)
   

1. Uses Permitted: No building or part thereof or other structure shall be erected, altered, added to or enlarged, nor shall any land, building, structure or premises be used, designated, or intended to be used for any purpose, or in any manner other than is included among the uses hereinafter listed as permitted in the district in which such building, land or premises is located.
   
2. Height Limitations: No building or part thereof or structure shall be erected, reconstructed or structurally altered to exceed in height the limit hereinafter designated for the district in which such building is located, unless building height exception is expressly allowed.
   
3. Area Regulations: No building, structure, or part thereof, shall be erected, nor shall any existing building be altered, enlarged or rebuilt or moved into any district, nor shall any open space be encroached upon or reduced in any manner, except in conformity to the yard, building site area, and building location regulations hereinafter designated for the land use and the district in which such building or open space is located. (Ord. 040202, 4-2-2002)

3. Procedure For Map Change: If, in accordance with the provisions of this title and Utah Code § 10-9-401 et seq., changes are made in district boundaries or other matters portrayed on the official zoning district map, an entry shall be made, as soon as practical after the amendment has been approved by the city council, on the official zoning district map according to the requirements of subsection B of this section.

5. Official Map Sole Authority: Regardless of the existence of purported copies of the official zoning district map, which may from time to time be made or published, the official zoning district map, which shall be located in the building and zoning department offices, shall be the final authority as to the current status of zoning districts.
   
6. How Replaced If Necessary: In the event that the official zoning district map becomes damaged, destroyed, or lost, or difficult to interpret because of the nature or number of changes and additions, the city council may, by ordinance, adopt a new official zoning district map or any subsequent amendment thereof. The new official zoning district map shall be identified as defined in subsection B of this section.
   
7. Prior Official Maps To Be Preserved: Unless the prior official zoning district map has been lost or destroyed, the prior map or any significant remaining parts thereof shall be preserved, together with all available records pertaining to its adoption or amendment. (Ord. 040202, 4-2-2002)
