1. Buildings in a group dwelling development shall meet the underlying zoning district's minimum setbacks from the exterior property lines. Group dwellings in residential zones may reduce the rear setback to match the minimum side setback of the underlying zone.
2. If any main building is adjacent to an off-site single-family residential (R-1) zoned property and is over 2-1/2 stories or 35 feet in height, it shall follow the setback standard in Subsection 15-13-5D.
Setback Diagrams for Tall Buildings
B. Distance Between Buildings: The minimum distance between buildings without a street, alley, or private drive in between shall be based on the orientation of each building within the development. The minimum separations are shown in Table 15-10-4.1
Maximum porch or patio encroachment into minimum separation is six feet. *Minimum separation is increased five feet for each story the taller building is above 2 ½ stories.
Minimum Building Separation Standards
Garden-style apartments that are U-shaped and up to 2-1/2 stories in height shall have a 35 foot minimum separation between units that face one another. U-shaped buildings taller than 2-1/2 stories shall have a minimum one to one (1:1) height to building separation requirement between units that face one another.
Minimum U-Shaped Building Separation Standards
a. Buildings that are adjacent to a public street shall have a front elevation that faces the street. If the building is on a corner that abuts two streets, only one front elevation is required for the building.
b. Building entrances not adjacent to a public street shall face any private street within the development, connecting walkways, plazas, parks, or similar outdoor spaces, but not parking lots.
c. All entrances facing the public street shall have a minimum six foot wide sidewalk connection to the public sidewalk.
2. Exception: The planning commission may consider other orientations of the building if there is not an existing neighborhood that fronts the street or if other conditions exist that restrict such development and the planning commission determines that the surrounding neighborhood identity, front yard appearances and streetscape continuity will not be impacted by such a design. If it is determined that the front elevation should not face the street, an additional 10 foot setback shall be added to the minimum front yard or street facing side yard setback required for main dwellings. The 10 foot setback area adjacent to the street lot line shall be landscaped with one deciduous tree every 40 linear feet of frontage and plants and shrubs that have a minimum coverage of 50% of the landscaped area at mature growth. Any fencing that is installed shall not be placed closer than 10 feet to the front or street facing side property line.
1. All four sides of the building, excluding doors and windows, shall have the same proportionate use of exterior finish materials (e.g., if brick is used on the front of the building it also is used on the other three elevations of the building).
a. Approved materials require at a minimum the first floor to be finished in brick, stone, or pre-cast concrete that has the appearance of masonry. Floors above the main level shall be finished with brick, stone, cement fiberboard, or pre-cast concrete that has the appearance of masonry, cement fiberboard, stucco, EIFS, or architectural metal. No more than two main materials shall be allowed per building with other approved materials being utilized as accent materials. Vinyl and aluminum siding are not permitted materials.
b. In considering other building material options, the design needs to bring continuity to the entire building, development and neighborhood (e.g., privacy fences made of similar building materials that block the view of other portions of the building, quoins used to give relief to corners, facades having physical changes in the vertical planes so a flat facade is avoided). The commission may also consider other options when there are substantial grade differences from one side of the building to another and variations in the material will not impact neighborhood continuity.
c. Projections or recesses are required along all building exteriors at a minimum of one projection or recess every 25 feet for buildings up to 100 feet long. Buildings 100 feet or longer shall have a minimum of one projection or recess every 40 feet. The projection or recess shall be a minimum of two feet from the main building wall. A change in material is required for projections that shall extend the entire height of the building from the level of origination above the main level to the building cap. However, when projections are used for stucco, or EIFS building exteriors, the projection shall be finished with the main material of the base (brick, stone, pre-cast masonry) from base to cap. Projections or recesses along the rear façade may be less than two feet but shall be one foot or more from the main building wall. Projections or recesses along the rear façade shall have a minimum of one projection or recess every 40 feet. Projections or recesses may vary within five feet of the minimum projection or recess interval as long as the average meets the minimum requirement. Townhomes may meet the projection or recess requirement by staggering each unit.
2. Architectural detailing is required in order to provide interest and theme to the buildings. At a minimum, the building designs shall have a covered entry porch, stoop, portico or similar and at least three of the following architectural elements which provide a defined character to the building:
e. decorative cornice work.
h. roof style other than gable.
i. balcony - three-foot minimum depth; Juliet (faux) or functional.
k. all facades of each building contain at least 30% brick or stone.
3. For commercial buildings and for multiple-family dwellings, a clearly defined entry feature shall be required that includes:
a. a different material or color;
b. a three foot deep entrance cover;
e. for a multiple-family dwelling building, at least three of the following:
(3) raised corniced parapet over the entry door;
(7) architectural details such as tile work and moldings which are integrated into the building structure and design; or
(8) integral planters or wing walls that incorporate either or both of landscaped areas and places for sitting.
4. Mix of building types: To provide variety in larger group dwellings, neighborhood and mixed-use group dwellings shall provide a mix of alternate building types.
a. Number of alternate building types required:
(1) Neighborhood group dwellings in the R-2 zone shall provide at least two alternate building types.
(2) Neighborhood and mixed-use group dwellings on sites under four acres shall provide at least two alternate building types.
(3) Neighborhood and mixed-use group dwellings on sites four acres or larger, other than in the R-2 zone, shall provide at least three alternate building types.
b. Alternate building types: The alternate building types to select from are the following:
(2) stacked units (duplex, triplex, fourplex);
(3) single family rowhouse;
(5) duplex, side-by-side;
(7) single family dwelling;
(8) garden apartment or courtyard dwelling; or
(9) for development in a commercial zone, a mixed residential/commercial building or standalone commercial building.
c. Alternate building designs: Buildings of the same type with more than one building design may count as two different building types.
(1) To qualify as different building designs, the buildings must differ in all of the following:
(a) height difference of at least eight feet or one story;
(f) porch or entrance feature; and
(g) at least two other architectural details.
(2) Single-family rowhouses designed so each rowhouse appears to be a different building than adjoining rowhouses may count as two different building types. To qualify, the adjoining rowhouses shall differ with all of the following:
(a) A vertical break of at least one foot in the roofline at the dividing line between rowhouses;
(b) A difference in predominant color and siding material between adjoining rowhouses;
(c) A horizontal offset in wall plane of at least one foot at the dividing line between adjoining rowhouses or distinctly different building projections on adjoining rowhouses;
(d) at least two other architectural details.
5. The architecture shall be visually compatible with the common elements of the existing architecture in the area. The planned architectural theme shall as a minimum use the common elements of the existing architecture in the area with respect to:
a. Roof Design and Pitch: Group dwellings shall be compatible with the architecture and common roof design and pitch within the area. Group dwellings may be designed with flat roofs if the architecture is visually compatible with the existing architecture of the area. The planning commission may allow a different roof design or pitch if the development is along the edge of a neighborhood, and it will not change the nature of the neighborhood.
b. Glazing: Facades facing a public street shall have glazing on at least 20% of the façade along the ground floor. If a group dwelling is required to include a commercial component, then 50% of the commercial frontage along the ground floor shall include glazing. The percentage is based on the ratio of solid materials (walls) to glazing materials (windows).
c. In the event the neighborhood is in transition or does not have a dominant architectural theme, the commission may approve architecture designs that enhance the neighborhood fabric.
6. The architecture of the dwellings shall have visual relief in facade and rooflines that add variety and rhythm to the design, and avoids monotonous straight lines.
7. The front of each dwelling structure shall be designed so that:
a. If a dwelling has a front-loaded garage along a public or private street, then the front- loaded garage doors shall occupy 40% or less of the ground level building frontage that faces the street.
(1) If the garage is rear-loaded and is accessed from an alley or private drive and the front door faces a green space or public street, then the rear-loaded garage can occupy the entire rear façade.
(2) If the front door to the dwelling unit is next to the garage and the garage faces an internal driveway or street, then the 40% maximum shall apply.
(3) If a side-loaded garage is accessed from a public or private street, the garage door(s) shall not occupy more than 40% of the building's side street-facing façade.
(4) Residential buildings that have garages along a private drive may be considered rear-loaded units if the private drive only has a single connection to a public street and does not have any other street connections to other neighborhoods.

b. A front-loaded garage shall be set back five feet behind the front of the building.
Residential Building Frontage Calculation (below)
E. Site Layout: The materials and height of the building are to be sensitive to the existing topography and vegetation that exist on site. The buildings shall be built into the existing topography so that no major cuts occur (i.e., if for example the site slopes the building should be stepped into the hill). The existing vegetation shall be identified and shown how it will be preserved on site. In the event that areas of vegetation are proposed to be removed, removal shall occur only upon approval by the planning commission based upon a site analysis and revegetation plan that is sensitive to the existing topography and vegetation.
F. Building Height: The height of the main buildings shall be limited to the maximum height allowed in the respective zone of the project. Accessory buildings shall be one story with a maximum height of 15 feet.
G. Parking Requirements and Design:
1. a. Two parking stalls per dwelling shall be required for each unit in the development in all zones except for multiple-family dwellings in commercial zones. One covered parking space shall be provided for each dwelling unit in all zones.
b. In commercial zones, multiple-family dwellings shall including parking on the property at a minimum of 1.75 stalls per unit and a maximum of 2.1 stalls per unit.

d. All parking and access shall be hard surfaced. Front-loaded garages shall be set back 18 feet from the street. If there is an existing sidewalk or a sidewalk is planned along the street, then the front-loaded garage shall be set back 18 feet from the existing or planned sidewalk. Units without attached garages or on-site parking shall have parking provided within a 100 foot radius, measured from any entrance of the dwelling unit.
2. Driveways shall be a minimum of 28 feet in width whenever the driveway is used to provide ingress and egress to any parking space between dwellings including parking within attached garages.
3. On-site parking adjacent to any public street and any access parallel to the street shall follow the underlying zone's front setback. Parking stalls and access lanes shall be set back a minimum of eight feet from any property line that is not adjacent to a street. The eight foot setback area shall be landscaped only with water-wise shrubs spaced so that at mature growth they cover a minimum of 50% of the planter surface area and trees spaced between 25 feet to 40 feet on center and irrigated by a drip irrigation system. Mulch shall be placed to cover the ground under and around plants and in areas without plants at a depth of four inches for wood bark or chips and at a depth of twice the size of any gravel or small stone mulch but in no case less than three inches thick. The planning commission may reduce the eight foot setback for access lanes if it is determined that the accessway is adequately screened, the proximity and amount of traffic will not adversely impact existing neighboring uses, and there is adequate landscaping to soften the appearance of the access area (see illustrations below).
Landscape buffer along interior property lines for parking and access lanes
4. Landscaped islands shall be required at the end of each row of stalls if the row exceeds 10 parking stalls in length. A row of parking that has over 20 parking stalls shall have one landscaped island placed between every 20 stalls in the row. Required parking areas shall install landscaped islands with raised curbs. Islands shall not be placed over hard surface. The landscaped island shall be a minimum width of nine feet and a minimum length of 18 feet. Landscaping in the islands shall be limited to the required trees and either rock mulch or water- wise shrubs installed as the ground cover in the islands. Trees and shrubs shall be irrigated by an appropriate drip irrigation system.
5. All development shall provide a clearly defined four foot wide sidewalk connection from parking lots to building entrances that utilize a different material or texture than the paved parking area.
6. Bicycle parking is required for all developments:
a. Residential developments shall provide one secure bicycle parking space for every four dwelling units not provided with a garage space. The parking space shall be capable of fully enclosing the bicycle in a locked area, such as in an enclosed storage room or bicycle locker. This does not include interior living spaces or balconies.

Plant selections shall be those plants listed as water-wise by various regional resources as acceptable plantings for northern Utah climate and irrigated by an acceptable drip irrigation system that meets the requirements found in Chapter 15-28 and two inch caliper shade trees spaced no farther than 40 feet apart on center. Street trees are required along interior roads whether public or private with a maximum spacing of 40 feet on center. A "private road" shall be defined as any interior road that is accessed from a public street, no parking backs onto the road, and is used for primary circulation within the development.
7. Incorporation Of Natural Features: Developments shall be designed to incorporate existing trees, clusters of trees or clusters of shrubs and natural settings along rivers, streams or canals. Significant trees and significant groves shall be preserved to the extent reasonably feasible. Existing trees and shrubs within areas that can be developed (excluding river setbacks/buffer zones, floodways and wetlands areas) may be used to satisfy the landscaping requirements of this section. All required landscape plans shall accurately identify the locations, species, size, condition and proposed disposition of all significant trees or significant groves. The planning commission shall review the appropriateness of removal of portions of these types of vegetation if removal is planned. The planning commission may approve removal of some or all vegetation based on a determination of the benefits of the existing plant material and the efforts made to save and incorporate the existing plant material into the design of the project versus the problems the plant materials may create for the project in terms of general construction techniques, impact removal will have to the character of the area, the topography of the site, and harmful conditions the vegetation may create. If existing vegetation is removed prior to submittal or not in keeping with the approved plan, the maximum density allowed for the development shall be the area requirement for single-family units in the zone of the project.
8. Use Of Turf Grass Limited: All required landscaping areas in front yard setbacks, side yard setbacks and side yard setbacks facing a street as well as landscaped areas between buildings and parking, buildings and street, parking and property lines, buildings or parking and access lanes and spaces less than 15 feet between buildings shall be landscaped only with water-wise landscaping. Plant selections shall be those plants listed as water-wise by various regional resources as acceptable plantings for northern Utah climate and irrigated by an acceptable drip irrigation system that meets the requirements found in Chapter 15-28. The water-wise shrubs shall be spaced so that at mature growth they cover a minimum of 50% of the planter surface area and irrigated by a drip irrigation system. Mulch shall be placed to cover the ground under and around plants and in areas without plants at a depth of four inches for wood bark or chips and at a depth of twice the size of any gravel or small stone mulch but in no case less than three inches thick. The use of turf grass is limited to areas of high foot traffic and recreational areas and landscape area outside of high foot traffic and recreational areas shall not exceed 20% of the total landscaped area of the development. For development over 100 units, additional turf grass may be permitted if limited to outdoor recreation areas in the development.
9. Minimum Plantings Required:
a. All areas of a developed site not occupied by buildings, required parking, driveways, walkways, or service areas shall be landscaped according to an approved landscaping plan. The plan shall meet the landscaping requirements for multiple-family residential development in Subsection
15-4-5.E. These areas may also incorporate hardscape for patios, plazas, and courtyards.
b. Outdoor recreation spaces shall be landscaped with deciduous trees that have a minimum two inch caliper and evergreen trees that are at least six feet in height based on the following formula: T= the total number of required trees (rounded to the nearest tenth decimal) and A = the total combined recreational open space and landscape area in square feet:
Example: (T) 15 Trees = (A)15,000 s.f. ÷ ((0.008 x (A)15,000 s.f.) + 880)
10. Minimum Landscaped Area Abutting Parking Or Access Lanes: A minimum six foot landscaped area excluding sidewalk shall be provided between the unit and any surface parking or access lanes.
11. Entrance Feature Required: An entrance feature to the development is required. The minimum entrance feature shall consist of a monument sign naming the development surrounded by a variety of ground covers, shrubs and trees.
12. Screened Enclosures: All dumpsters shall be stored in screened enclosures that are architecturally compatible in style and materials with the architecture of the development. Dumpsters shall be located so they are not in the required setback areas, not visible from the public street and do not restrict vehicular parking or circulation.
13. Stormwater Detention Facilities: Stormwater detention facilities are designed and used for multiple functions. The design of the facility shall blend in with the overall theme of the open space. Factors that will be used in determining compliance may include, but not be limited to, freeform design, grading and landscaping to provide gradual transitions, or artistic design elements.
14. Neighborhood Group Dwellings: Neighborhood group dwelling's outdoor recreation space shall meet the requirements of Subsection H.3, but shall not be required to provide open space based on number of units as required by Subsection H.3(a) or (b). Neighborhood group dwellings shall include outdoor recreation space at a minimum of 15% of the total development area.
a. The outdoor recreation space shall be delineated by a sidewalk, decorative fence, or natural feature to distinguish common area for all residents from private outdoor space.
b. The required yard setbacks from property lines shall not be included in meeting the 15% outdoor recreation space minimum unless it is 20 feet wide and designed for outdoor recreation use. Linear space between buildings may be considered outdoor recreation space if it includes an area with turf grass that is 15 feet or wider, is delineated from private outdoor space and protects the privacy of adjacent residents.
c. If neighborhood group dwellings include private outdoor living space (private patio, front court, or similar) for individual units, then 30% of the private outdoor living space may count towards the 15% outdoor recreation space minimum.
d. The private outdoor living space shall include either a covered porch with a six foot minimum depth, or a front court, patio, or similar area with a 100 square foot minimum area in order to count towards the 30% outdoor recreation space minimum. These areas must be shown as limited common areas on the final plat.
e. The outdoor recreation space minimum shall not include sensitive lands areas, such as wetlands, ridge lines, or steep slopes that are greater than 30%. The outdoor recreation space shall be designed to provide usable recreational open space to owners and guests for activities such as sports, picnics, child play, or gardening. It may include hard surfaces such as sports courts or patios.
I. Street Design: Group dwellings shall be designed to meet area transportation plans. Developments that are located on or next to a collector or arterial public street shall be designed and developed so the public street continues through the project in a logical, safe design. Projects that are located at the end of stubbed local streets or in areas where local streets may be of benefit to the development of the general area may be required to design and install a local public street through the development. The planning commission shall review the future and existing circulation needs of the area, existing road patterns, and emergency access needs in determining if a local public street should be required or extended. Interior private [roads shall have a minimum 24 foot pavement width.
1. Requirements: The portions of the development that do not front a street shall be fenced with a maximum seven foot high fence. The fence needs to be constructed out of either masonry, wood, vinyl or black powder coated chainlink. Fencing in the front yard is optional. The maximum height for a fence in the front yard setback is four feet high. Front yard fencing shall be constructed out of masonry, wood, vinyl or decorative wrought iron.
2. Exceptions; Maintenance; Waivers:
a. The planning commission may vary the height of the fence fronting a street if the buildings do not front the street and it is determined the proposed fence design, materials, and location will not create a safety hazard due to obstructed vision of approaching vehicles or pedestrians and will:
(1) not isolate the surrounding neighborhoods;
(2) be consistent with the theme of the development; and
(3) be compatible with the neighborhood.
b. If fencing isolates property between the fence and the public street, the development shall provide a means to ensure continued maintenance of this area.
c. The planning commission may waive the seven foot high fencing requirement provided it is determined that:
(1) waiving such fencing will not impact adjoining properties by creating potential trespassing conditions; and
(2) there is a natural or manmade feature that fencing would hinder access to or damage the aesthetic attributes of the feature as it relates to the development.
K. Amenities: Amenities included in all group dwellings shall include the following:
1. laundry hook-ups provided in each dwelling unit.
2. in multiple-family dwellings of 20 or more units:
