Notwithstanding the Regulations of General Applicability in CZC 12.32.060 and the Table of Development Standards in CZC 12.32.300, all residential development within the R-M and R-H Zones shall comply with the following development standards.

1. Architectural Design Standards. All primary buildings within the R-M and R-H Zones shall be designed by a licensed, professional architect and all drawings submitted for approval or permit shall bear the architect’s stamp for the State of Utah.  
2. Exterior Design Standards. All sides of primary buildings within the R-M and R-H Zones shall receive design consideration with particular attention given to areas exposed to public view. 
   1. All primary buildings within a development project shall possess an overall building architectural theme, including, but not limited to, exterior building materials, textures, colors and signage. 
   2. The apparent mass of primary buildings or structures shall be minimized through design, articulation, and use of materials. An open design is desired that visually and physically breaks up the mass and footprint of buildings. Approaches such as the use of vertical and horizontal planes, roof pitches, roof lines, windows, reveals, and alcoves shall be used to create façade variation, shadows, corners, and architectural interest. Articulation approaches should not appear to be applied randomly or merely a surface treatment. In addition, the use of any multiple articulation approaches shall be coordinated to affect a complementary building design.
   3. Natural or natural-appearing materials, such as stone, cultured stone, brick, and wood, shall be the design gestures used in the architectural design of all primary buildings. Wood siding, cement fiber board siding, and other similar appearing materials shall be the other main materials used in the design of all residential buildings. Substantial or prominent use of synthetic stucco, and unnatural appearing materials, such as metal, vinyl, and plastics are to be used sparingly. Use of such secondary and/or accent materials shall not exceed 20% of the building or structure’s exterior.
   4. The Planning Commission shall review and approve architectural design of buildings within the R-M and R-H Zones in accordance with the provisions set forth herein during conditional use permit and/or site plan review. 
3. Landscaping and Open Space. All residential developments within the R-M and R-H Zones, except for single-family developments, shall comply with the landscaping regulations of CZC 12.51 (Landscaping and Screening), and more specifically, the regulations of CZC 12.51.070(g) regarding multi-family developments. Additionally, landscaping and open spaces shall be designed in a manner to meet the residential needs for active and passive spaces for residents and visitors, such as private spaces, entry features, small centralized gathering areas, and buffering adjacent land uses. Furthermore, such areas shall be designed with the amenities or features that complement the various expected residents, both day and evening hours, and beyond the default design of a tot lot, playground, or clubhouse.  
4. Use of Public and Private Roadways. All dwellings within residential developments in R-M and R-H Zones shall be accessed from a public roadway, unless otherwise approved as part of a planned development or condominium (See, CZC 12.55.150). Approved access from a private right-of-way shall meet the following standards:
   1. Access to and from a public street may be in the form of private right-of-way or a driveway, as defined or required by this Title. 
   2. Two points of ingress/egress from a public right-of-way shall be established for any development greater than 20 dwellings, irrespective of the allowed gross density.
   3. When a private right-of-way is utilized, the private right-of-way pavement (i.e. travel lanes) shall be at least 27-feet and the constructed cross-section with curb and gutter of the roadway shall be built to City Specifications.
   4. Access using a private right-of-way shall be constructed with a sufficient width to provide on-street parking for visitors at a ratio of at least 0.5 stalls per dwelling. An exception may be provided to this ratio if visitor parking is provided by separate parking area or parking lot as part of a site plan approved by the City.
   5. A sidewalk system shall be provided on both sides of any private right-of-way. An exception may be provided to this requirement if an alternate integrated development pathway system connecting to the public right-of-way and serving the dwellings is provided to satisfy the requirement for sidewalks, as part of a site plan approved by the City.
   6. A private right-of-way shall be perpetually maintained by the developer or an owner’s association.  Such perpetual care and maintenance obligations shall be addressed with covenant, conditions, and restrictions, for the development approved by the City and recorded against the property.     
   7. A private right-of-way design shall also comply with all applicable Fire Code regulations.
5. Residential Development Style Limitations for R-M Zone.  The residential development style for residential development within the R-M Zone shall be limited to single-family dwellings, twin homes, duplexes, or townhomes in tri-plex, four-plex, and six-plex formats that mimic a typical neighborhood style street on public or private roadways (as described in Subsection (d)).  Higher density design formats such as stacked flats or apartment style buildings or buildings constructed with associated vehicular parking lot style facilities are prohibited in the R-M Zone.  

The use and development of real property in residential zones shall conform to regulations of general applicability as set forth in the following Chapters of this Title.

1. CZC 12.50 (Existing Conditions Inventory)

1. Waivers Authorized. Notwithstanding the hard surfacing limitations set forth in Section 12.32.300, the Planning Commission may approve a greater amount of hard surfacing on a lot or parcel that does not contain a dwelling use, in conjunction with a landscaping waiver as outlined in CZC 12.51.050, if required.
   
   1. A waiver may be allowed, provided that a minimum 15-foot landscaped buffer, as outlined in CZC 12.51.070(b), shall be maintained along all interior and rear lot lines.
      
2. Application. A person desiring a waiver from requirements of this Chapter, with regards to hard surfacing requirements, shall, in conjunction with an applicable development application, submit a written request which describes the proposed waiver, provides grounds justifying the waiver, and shows how the intent of this Chapter will be met by the proposed waiver.
   
3. Findings Required. The Planning Commission may authorize a waiver from the requirements of hard surfacing limitation set forth in Section 12.32.300, to the extent authorized herein, only if it finds the waiver:
   
   1. Preserves the intent of this Chapter and the provisions for which a waiver is authorized.
      
   2. The granting of a waiver will not result in an adverse impact on the surrounding properties; and
   3. 1. The strict application of the provision in question is unreasonable or unnecessary for the specific use, design or site proposal given the nature of the proposal or alternate measures proposed by the applicant; or
      2. The property has extraordinary or exceptional physical conditions that do not generally exist on nearby property in the same zone and such conditions will not allow strict compliance with the provisions of this Chapter.
