A.   The AA, A and AE Zones are intended to provide areas for the keeping of farm animals and fowl in conjunction with single- family dwelling units to an extent consistent with said development and in proportion to the amount of land area provided for this purpose.

   B.   The AE Zone is expressly established to accommodate residential developments which are oriented to a lifestyle that includes farming which is generally noncommercial. To accomplish this purpose, this chapter includes provisions which encourage the design of residential communities to include noncommercial stables, training areas and equestrian trails as part of the development.

   C.   Property in the AA and A Zones is intended to be used primarily for commercial agriculture, farming and large estate parcels for residential living. Additionally, the AA Zone is created to apply to environmentally sensitive areas, such as floodplains, wetlands, debris flow areas, areas within one hundred feet (100') of a stream channel, all land above an elevation of five thousand two hundred feet (5,200') above sea level, all land below an elevation of four thousand two hundred eighteen feet (4,218') above sea level. (Ord. 1999-17, 4-21-1999)

   D.   All lands within agricultural zones are intended, to some extent, for either private or commercial agricultural production, farming, protection of environmentally sensitive areas and/or open space. Owners, occupants and users of these properties, or neighboring properties, may be subjected to inconvenience, discomfort and the possibility of injury to property and health arising from normal and accepted agricultural practices and operations, including, but not limited to, noise, odors, dust, the operation of machinery, including crop dusting aircraft, the storage and disposal of manure, and the application of fertilizers, soil amendments, herbicides and pesticides. Owners, occupants and users of these properties, or neighboring properties, should be prepared to accept such inconveniences, discomfort and possibility of injury from normal agricultural operations and are hereby put on official notice that Utah Code Annotated section 78B-6-1104, as amended, may bar them from obtaining a legal judgment against such normal agricultural operations. (Ord. 1999-17, 4-21-1999; amd. 2016 Code)

The following table identifies permitted uses by the letter “P” and conditional uses by the letter “C”. The letter “X” indicates that the use is not allowed. Uses not listed shall not be allowed, except as provided in subsection 11-4-050F of this title:

 

(Ord. 2017-13, 5-16-2017; amd. Ord. 2020–7, 5-5-2020; Ord. 2021-25, 9-21-2021; Ord. 2022-62, 12-6-2022; Ord. 2023-13, 3-14-2023; Ord. 2023-40, 6-20-2023; Ord. 2025-37, 7-15-2025)

Residential subdivisions within agricultural zones greater than five (5) acres in size, or located in the Conservation Subdivision Overlay Zone, as described on the Farmington City zoning map, may be developed in accordance with the provisions of chapter 12 of this title providing innovative and flexible subdivision design options. (Ord. 2014-33, 10-7-2014)

 

 

   B.   Additional Lot Alternatives And Standards:

      1.   Alternatives:

         a.   Open Space: As an incentive for a subdivider to provide open space, the City, at its discretion, may approve a transfer of development right (TDR) or conservation subdivision as follows:

            (1)   Additional lots are those the City approves in exchange for a TDR as set forth in section 11-28-240 of this title; or in exchange for which the City obtains improved or unimproved land in fee title, or easement, for public purposes, such as parks, trails, detention basins, etc. The value of which, and the total number of lots related thereto, shall be determined by the City at its sole discretion as part of the subdivision process. Any applicant seeking additional lots under this section must provide a subdivision yield plan as defined in Chapter 2 of this title consistent with the underlying zone and the conventional subdivision standards within that zone to establish the base number of lots allowed prior to a request for additional lots, and the yield plan must also conform to subsections 11-12-070A and B of this title.

            (2)   Additional lots under this section may also be available for subdivisions consisting of five (5) acres or more, or for subdivisions located in the Conservation Subdivision Overlay Zone as set forth in Chapter 12 of the title “Conservation Subdivision (CS) Overlay Zone And Development Standards”; or

         b.   Moderate Income Housing: The City may approve a smaller lot size as set forth in the following table which will result in additional lots than what is conventionally allowed in the underlying zone as an incentive to a subdivider to provide moderate income housing.

 

 

            (1)   Minimum Requirement: Subdividers must provide or set aside lots (or dwelling units at the option of the City) equal in number to at least ten percent (10%) of the total number of lots approved for the subdivision for moderate income housing subject to recording a deed restriction(s) to ensure the required number of lots or units are available for a qualifying moderate income household; unless, at the sole discretion of, and by agreement with the City, the subdivider provides:

            (a)   A fee in lieu thereof determined in consideration of factors set forth in Section 11-28-270 of this Title;

            (b)   Preserve an existing on-site historic resource (standards for historic resources are set forth in Chapter 11-39 of this Title); or

            (c)   Some other public benefit; or

            (d)   A combination of (a), (b), and/or (c) above.

      2.   Alternate Standards:

         a.   Following the subdivision yield plan defined in Chapter 11-2 and using the minimum standards of subsection A to establish a maximum number of lots, a subdivider may alter the lot area, width, setback, and other dimensional requirements of lots within a subdivision using standards set forth in subsection 11-12-070C.

         b.   Lot area, width, setback, and other dimensional requirements for additional lots may meet such standards set forth in Chapter 12 of this title, but the number of lots in the subdivision cannot exceed the total number of lots resulting from the respective yield plan identified in section 11-12-070.

   C.   Lot Coverage. The gross area of a lot covered by the main building, accessory buildings and other structures shall meet the following standards:

      1.   Lots Less than 0.5 Acres in Area. The coverage and size requirements set forth in Chapter 11 of this title shall apply.

      2.   Lots Equal to or Greater than 0.5 acres in Area. A coverage base of 6,000 square feet plus one square foot of additional coverage for every eight (8) square feet of gross lot area more than 0.5 acres (or 21,780 square feet), but the base plus additional coverage shall not exceed 20,000 square feet. For illustrative purposes, the table below shows a few of the many possible coverage outcomes on the continuum between 6,000 and 20,000 square feet.

 

 

   D.   Area Required For Class B Animals: Not more than two (2) horses or cows, or four (4) sheep, goats, pigs or similar size animals shall be kept on a one- half (1/2) acre lot. For lots larger than one-half (1/2) acre, one additional horse or cow, or two (2) additional sheep, goats, pigs or similar size animals may be kept for each five thousand (5,000) square feet over one-half (1/2) acre. Animals younger than six (6) months in age shall not be counted in determining the total number of animals on the lot.

   E.   Area Required For Class C Animals: The minimum lot size for Class C animals (commercial farming) shall be five (5) acres. Class C animal operations shall not include hog, mink, turkey and chicken farms.

   F.   Area Required For Sportsman Kennel: The minimum lot size for a sportsman kennel shall be one acre.

   G.   Conservation Subdivisions: Land within greenbelt corridors, waterways and trail dedications shall not be used in calculating final lot area in conservation subdivisions.

   H.   Accessory Buildings And Structures:

   I.   Transmission Towers: Transmission towers, except as specified in section 11-28-190 of this title, shall be set back from all property lines a distance equal to the height of the tower plus thirty feet (30'). (Ord. 2014-33, 10-7-2014; amd. Ord. 2015-16, 5-26-2015; Ord. 2018-18, 5-15-2018; Ord. 2019-23, 7-16-2019; Ord. 2020-08, 5–5-2020; Ord. 2021-20, 8-9-2021; Ord. 2022-62, 12-6-2022; Ord. 2023-13, 3-14-2023; Ord. 2023-42, 7-18-2023; Ord. 2024-06, 1-16-2024; Ord. 2024-41, 7-16-2024; Ord. 2025-32, 6-17-2025)

   B.   Parking Restrictions: In an AE Zone, minimum parking required by this title shall not be located within the minimum required front or side yard setback adjacent to a public or private street. Surfacing of access drives to such parking shall be either gravel, asphalt or concrete in order to minimize tracking of dirt onto public roads.

   C.   Temporary Buildings: Temporary buildings, or the temporary use of a building or yard, shall only be allowed in conjunction with a construction project. Temporary buildings may be used only as an office or for storage of equipment or materials. The temporary building or use shall be removed and/or terminated not less than thirty (30) days after final inspection of the construction project or one year after issuance of the building permit, whichever comes first.

   D.   Trail Dedications: Developers of major subdivisions in agricultural zones may be required by the City to dedicate equestrian and/or pedestrian trails, waterways or other open space corridors in order to allow internal circulation, separated from vehicular traffic, and connections to a regional trail system. At the discretion of the City, such dedications may be made in lieu of the park acquisition and development fee required by, and according to the standards established in, the subdivision ordinance.

   E.   Major Street Plan: All developments shall comply with recommendations of the City's major street plan. (Ord. 1999-17, 4-21-1999)
