§ 152.027 RESIDENTIAL DISTRICTS.

(A) General purpose. Residential zoning districts are primarily intended to create, maintain and promote a variety of neighborhoods that are comprised of a range of compatible densities to accommodate the desired physical character of the town. These districts primarily accommodate residential uses, however some nonresidential uses are also allowed to provide public facilities necessary to create a healthy and safe environment to live in.

(B) Residential districts.

(1) Residential-Estate/Two-Acre (RE-2A). This district is intended to provide an open, country residential atmosphere on large lots. Lots are typically larger than in the developed portion of the town and include keeping large livestock. Single-family detached homes in this district may include site built, manufactured, or modular. Mobile homes prohibited.

(2) Residential-Estate/One-Acre District (RE-1A). This district is similar in intent and purpose to the Residential-Estate District, except that the lot sizes are smaller. In general, the intent is to allow conventional single-family detached housing, with large livestock. Single-family homes in this district may include site built, manufactured, or modular. Mobile homes prohibited.

(3) Single-Family Residential-20 (R1-20). The intent of this district is to provide a transition from rural residential estate development to more urban residential neighborhoods. Development in this district is generally comprised of large-lot single-family detached homes with more conventional residential amenities such as sidewalks, public utility services and other improvements. Single-family homes in this district may include site built, manufactured, or modular. Mobile homes prohibited.

(4) Single-Family Residential-12 (R1-12). The intent of this district is to provide a transition from rural residential estate development to more urban residential neighborhoods. Development in this district is generally comprised of large-lot single-family detached homes with more conventional residential amenities such as sidewalks, public utility services and other improvements. Single-family homes in this district may include site built, manufactured, or modular. Mobile homes prohibited.

(5) Single-Family Residential-8 (R1-8). This district is intended to promote and protect the single-family character of a neighborhood and to prohibit incompatible activities. Development in this district should afford non-motorized linkages to community and neighborhood services such as schools, parks and shopping areas. All public utilities and facilities must be present. Certain essential and complementary uses are permitted under conditions and standards which ensure their compatibility with the character of the district. Single-family homes in this district may include site built, manufactured, or modular. Mobile homes prohibited.

(6) Small-Lot Residential-2 (R-2). The intent of this district is to provide for neighborhoods comprised of a mixture of single-family detached homes and small-lot residential dwellings such as duplexes, townhomes, or patio homes together with schools, parks, trails and other public facilities. This district may serve as a transition between higher-density multi-family residential districts and low-density single-family residential districts. Single-family homes in this district may include site built, manufactured, or modular. Mobile homes prohibited.

(7) Multiple Family Residential-3 (RM). This district allows the broadest range of multi-family residential types and is intended for locations closer to primary intensity generators, such as large shopping areas or employment centers. The district requires direct connection to higher volume roadways and all public utilities. Provisions for various modes of travel and pedestrian linkages are also critical.

(8) Manufactured Home Subdivision (MHS). The intent of this district is to provide an alternative single-family living style for those families who choose a manufactured home environment. Development in this district consists of subdivisions where residents own individual lots. The development standards of this district are intended to be consistent with the standards for other single-family neighborhoods developed at similar densities. All public utilities and facilities must be present.

(9) Manufactured Home Park (MHP). The intent of this district is to provide an alternative single-family living style for those families who choose a manufactured home environment, but lease or rent spaces rather than own individual lots. Recreational vehicle parks developed in a safe and attractive manner may also be located in this district. The development standards of this district are intended to be consistent with the standards for other single-family neighborhoods developed at similar densities. All public utilities and facilities must be present.

(C) Residential use standards. Table 2.1-1: Table of Allowed Uses for Residential Districts, lists land uses and indicates whether they are permitted by right or with approval of a conditional use permit, or prohibited in each zoning district. The Use Table also includes references to additional use-specific standards that may be applicable to that use. The organization headings and individual abbreviations utilized in the table are explained as follows:

(1) Use category. The “use categories” are intended merely as an organizational tool and are not regulatory. These use categories simply help to organize the list of “specific use types” into common groupings for ease of reference.

(2) Specific use type. The “specific use types” are regulatory and function as the basis for defining present and future land uses that are appropriate in each zoning district. Rather than list every possible individual land use type, this list classifies individual land uses and activities into specific use types based on common functional, product or physical characteristics; such as the type and amount of activity, the type of customers or residents, and how goods or services are sold or delivered and site conditions. Further definitions of each specific use type can be found in §§ 152.135 through 152.137.

(3) Permitted uses. "P" in a cell indicates that the use is allowed by right in that zoning district.

(4) Conditional uses. "C" in a cell indicates that the use is allowed in the respective zoning district only if reviewed and approved in accordance with the procedures of § 152.091.

(5) Not permitted. "NP" in a cell indicates that the use is not permitted/prohibited in that zoning district.

(6) Use-specific standards. Section numbers listed in the "Supplemental Use Regulations" column denote the location of additional regulations that are applicable to the specific use type; however, provisions in other sections of this chapter may also apply.

(7) Non-specified uses. When a use cannot be reasonably classified into a specific use type, or appears to fit into multiple specific use types, the Zoning Administrator is authorized to determine the most similar and thus most appropriate specific use type based on the actual or projected characteristics of the individual use or activity (including but not limited to size, scale, operating characteristics and external impacts) in relationship to the specific use type definitions provided in §§ 152.135 through 152.137. Appeal of the Administrator's decision may be made to the Board of Adjustment following the procedures under § 152.086(K).

(E) Residential site and architectural design guidelines. The purpose of this section is to help provide a pleasant residential environment within the context of higher density development. By applying principles of good design to aspects and components of multi-family residential development, the town can protect the fabric of existing neighborhoods as well as maintain the community's overall high intrinsic value.

(1) Applicability.

(a) These requirements shall apply to development of new multi-family dwellings or renovation of existing multi-family dwellings within the Multiple Family Residential-3 (RM) Zoning District that has frontage along State Route 389 in the town.

(b) These guidelines will be used by town staff and decision-making bodies as a framework for evaluating residential development proposals and for commenting on the design aspects of those proposed projects. The general development and subdivision regulations should also be referenced for additional site design standards specifically applicable to residential subdivision developments.

(2) Architectural guidelines.

(a) Natural materials and deep earthtone colors are preferred, and design elements should not consist primarily of metal, glass, plastic, highly reflective materials and bright colors. Such materials may have limited application in trim or accent areas, but should not be predominant visual elements of the building(s) or site improvements.

(b) Large bland monolithic facades or rooflines and repetition of very simple details which become monotonous in character should be avoided. Building elevations should create a unique character which is emphasized through interesting architectural details or façade articulation in each component. For example, windows may be arched or rectangular, bayed out or recessed, have raised borders, awnings, planter boxes or shutters.

(c) Simple, clean, bold projections of stairways are required to complement the architectural massing and form of the multi-family structure. Stairways should be of an approved building material as listed in § 152.026(E)(2)(d). Thin-looking, open metal, prefabricated stairs are not recommended.

(d) All building facades should be designed with architecturally finished materials, with the following recommended primary façade building materials:

1. Modular masonry materials such as brick, block, and stone;

2. Precast concrete or aggregate panels with a decorative finish;

3. Stucco or stucco-like materials;

4. Wood, provided the surfaces are finished for exterior use and wood of proven exterior durability; or

5. Other materials as determined by the Zoning Administrator.

(3) Site design/orientation guidelines.

(a) Buildings, structures, open space areas and other features shall be oriented to protect and/or enhance major vistas and panoramas that give special emphasis to mountains, and special man-made or natural landmarks.

(b) A system of attractive and safe pedestrian ways shall be provided which link the various components of the development with each other and link the site's pedestrian system with adjacent public pedestrian ways. They shall also link the dwellings with adjacent land uses such as parks, shopping centers, or schools, which are likely to be used by the residents of the development.

(4) Circulation.

(a) The primary vehicular access into a multi-family residential project shall be through an entry drive rather than a parking lot drive.

(b) Developments along ADOT controlled roadways shall complete a traffic study analysis, including access needs, traffic control needs, highway expansion needs, drainage management plan, and/or a cost sharing plan. ADOT approval will be required as part of the development plan approval process.

(c) Access points along primary gateway roadways shall be placed and designed in accordance with ADOT and/or town requirements.

(5) Utilities. All on-site electric utility and all other communication and utility lines for buildings shall be placed underground.

(F) Additional development standards.

(1) Setback and height exceptions. See §§ 152.135 through 152.137 for additional development and design regulations.

(2) Parking and loading requirements. See § 152.056 for additional development and design regulations.

(3) Landscaping and screening requirements. See § 152.057 for additional development and design regulations.

(4) Signage requirements. See § 152.058 for additional development and design regulations.

(5) Exterior lighting requirements. See § 152.059 for additional development and design regulations.

(6) Further reference, as appropriate, should be given to the town Uniform Building and Fire Codes, general development and subdivision guidelines, floodplain management ordinance, and engineering design standards.
