A. Minimum Area: The minimum area for a planned unit development shall be five (5) acres in AA, A, AE, LS and S Zones, two and one-half (21/2) acres in LR, R and R-2 Zones, and one and one- half (11/2) acres in R-4 and R-8 Zones. Any proposal for a planned unit development in areas smaller than those cited above, may be approved based upon the specific conditions related to the site upon which the development is proposed. Smaller planned unit developments are encouraged in the older historical parts of the City in order to use lot interiors where unique conditions may exist.
B. Base Density: The base density of the planned unit development shall be determined by the development of a yield plan, as defined in section
11-2-020 of this title, applying subdivision yield plan dimension standards set forth in chapter 12 of this title and related requirements of the underlying zone.
C. Lot Area, Width, Yard, Height, Coverage: Lot area, width, yard, height and coverage regulations shall be determined by approval of the preliminary PUD Master Plan.
D. Number Of Dwelling Units: The number of dwelling units in each building shall not exceed the number permitted in the zone when the underlying zone is R-4 or R-8. When the underlying zone is R-8, the maximum dwelling units in each building may be increased to twelve (12) units; provided, that the maximum allowable density of the R-8 Zone is not exceeded.
E. Adjacent Yard, Height Requirements May Apply: The Planning Commission may require that yard and height requirements of adjacent zones be applied to the periphery of the planned unit development.
F. Low Intensity: To assure that adjacent properties will not be adversely affected, the Planning Commission may require, where feasible, buildings and uses of lowest intensity be situated on the periphery of the planned unit development.
1. Requirements: Every planned unit development shall provide usable common open space, accessible to all lots or units, of not less than ten percent (10%) of the net area (gross area less constrained or sensitive lands), in single-family planned unit developments (see chart below) and thirty percent (30%) in multi- family planned unit developments. (Open space requirements in a mixed single-family, multi-family planned unit development shall be computed as a weighted average.) No streets, driveways, parking areas, yard areas typically used for individual structures or areas with slopes greater than thirty percent (30%), wetlands or other constrained lands may be included in the computation of the required open space unless the City determines that certain constrained, i.e., rock outcroppings, etc., qualify as unimproved open space in order to enhance the character and function of open space with the development. Playgrounds, parks, swimming pools and related amenities, tennis courts and similar bona fide recreation buildings and facilities and trailway system land may be considered part of the usable common open space.

2. Alternatives To Open Space: The City, as a legislative action concurrent with the consideration of a PUD and at its sole discretion, may enact one or all of the following alternatives in lieu of the required open space set forth herein:
a. Historic Preservation: The City, at its sole discretion, may consider preservation of an on site building or structure eligible, or that may be eligible, for the National Register of Historic Places in lieu of the ten percent (10%) open space.
b. Transfer Of Development Right (TDR): A TDR lot may replace all or a portion of the ten percent (10%) open space requirement consistent with the standards contained elsewhere in this title.
c. Waiver: The City may waive all or a portion of the ten percent (10%) open space requirement consistent with the standards set forth in this chapter. Any development receiving a waiver shall not qualify for a density bonus.
d. Moderate Income Housing: Developers may provide or set aside dwelling units equal in number to at least ten percent (10%) of the total number of dwelling units approved for the development for moderate income housing subject to entering into an agreement with the City; unless, at the sole discretion of, and by agreement with the City, the developer provides:
(1) A fee in lieu thereof determined in consideration of factors set forth in Section 11-28-270 of this Title; or
(2) Some other public benefit; or
(3) A combination of 1 and 2 above.
H. Increase In Residential Density: Residential density may be increased up to a maximum of twenty percent (20%) above that allowed in the underlying single-family zone, at the discretion of the City. The density will be determined during the preliminary PUD Master Plan review stage.
1. Common Open Space Increase: An increase of usable common open space in addition to the open space requirements cited in subsection G of this section, may allow the following density increases:
a. Improved: Improved open space is usable common open space that is highly accessible to all residents of the planned unit development; that is devoted to planting, patios, walkway, and recreational areas; that provides recreational facilities such as swimming pool, tennis court, clubhouse, playground, etc.; that is of such dimension to be functionally usable (on any section of improved open space shall not be less than 6,000 square feet nor less than 30 feet in its smallest dimension); and that is of a finished grade of twelve percent (12%) or less.
b. Unimproved: Unimproved open space is common open space that generally allows for the preservation of the planned unit development's natural amenities such as rock outcrops, trees, ravines, ponds, drainage channels, etc. All or part of unimproved open space is generally left in a natural state and its use is restricted to more passive recreation, such as hiking trails or creation of access to scenic vistas and natural sites.
2. Multi-Family Planned Unit Developments: A density bonus is not allowed in multi-family planned unit developments by increasing open space. Economies in construction and an increase in open space may be achieved by increasing the number of units per structure as provided in subsection D of this section.
3. Siting Variation: Character, identity and architectural and siting variation incorporated in a single-family planned unit development shall be considered cause for density increases not to exceed five percent (5%). When combined with open space density bonuses, the total density increase shall not exceed twenty five percent (25%). The degree of distinctiveness and the desirable variation achieved shall govern the amount of density increase the Planning Commission and City Council approve. Such variations may include, but are not limited to, the following:
a. Landscaping: Landscaping; streetscape; open spaces and plazas, use of existing landscaping and natural features; pedestrianway treatments; treatment of recreational areas and provision of various recreation apparatus (a maximum increase of 2 percent).
b. Siting: Siting; visual focal points; use of existing physical features such as topography; view; sun orientation; circulation patterns; physical environment; variation in building setbacks; and clustering of building groups (a maximum increase of 1 percent).
c. Design Features: Design features; street sections; architectural styles; harmonious use of materials; parking areas broken by landscape features; and varied use of house types (a maximum increase of 2 percent).
I. Utilities: All dwelling units shall be served by public sewer and public water. All utilities within the planned unit development shall be placed underground.
J. Off Street Parking: Off street parking spaces shall be provided as required in
chapter 32 of this title.
K. Dedicated Streets: All streets in a planned unit development shall be a dedicated public street built to Farmington City standards unless otherwise approved by the City Council. (Ord. 2018-05, 1-18-2018; amd. Ord. 2021-20, 8-3-2021)
