The purpose of this Section is to serve the public interest by requiring development in the City to meet certain minimum architectural design standards. Through a comprehensive review of both functional and aesthetic aspects of new or intensified developments, the City needs to accomplish all the following objectives:  Implement the goals and policies set out in its Comprehensive Plan;  Preserve the character of residential neighborhoods and the City's commercial and industrial areas;  Maintain and improve the City tax base;  Reduce the impacts of dissimilar land uses;  Promote orderly and safe flow of vehicular and pedestrian traffic;  Discourage the development of identical and similar building facades which detract from the character and appearance of the neighborhood;  Preserve the natural and built environment; and  Minimize adverse impacts on adjacent properties from buildings which are or may become unsightly. All properties must comply with all applicable provisions of the City Code including but not limited to the performance standards in this Section and all other applicable provisions of the Zoning Code. 1144.200: MULTI FAMILY DESIGN STANDARDS. The provisions in this Subsection apply to multi-family residential uses in the R-3 zoning district. These provisions apply to all new buildings and all additions to existing buildings. If an addition exceeds a 50% expansion of the existing building area, both the existing building and the addition shall meet the provisions of this Subsection. When only the building’s exterior is being renovated, the renovations may replace existing materials with new like-materials, or with permitted exterior materials identified in this Subsection. (1) Roofs that are exposed or an integral part of the building aesthetics shall be constructed only of commercial grade asphalt or wood shingles and be of an approved earth tone color. The visual impact of rooftop equipment shall be minimized using one of the following methods:  A parapet wall.  A fence or screen, the height of which extends at least one (1)-foot above the top of the rooftop equipment and incorporates the architectural features of the building.  The rooftop equipment shall be painted to match the roof facing material of the building. (2) The development must locate the noise-producing portions of the development, such as loading docks and outside activity away from adjacent residential areas. (3) Utility service structures such as utility meters, utility lines, transformers, generators, maintenance structures, and other ancillary equipment must be inside a building or be entirely screened from off-site views. (4) All utility services shall be underground except as provided elsewhere in the City Code. (5) Exterior surface materials of buildings shall be subject to the following regulations: a. Permitted Exterior Materials. The following materials shall be allowed as exterior finishes for all buildings: Brick, stone, stucco or EIFS synthetic stucco (provided the material shall not be allowed within four (4) feet from grade) architectural concrete precast panels, color impregnated decorative block, and glass. Architectural precast panels may be painted to the manufacturer’s painting specifications. Masonry materials such as brick, stone and block may be used as face or veneer, adhered, or anchored, as long as the exterior finish remains durable with high architectural quality. The following materials shall be allowed as exterior finishes for all buildings, provided that no more than 50% of any individual exterior wall shall consist of this material: fiber cement siding. This 50% limit may be exceeded only as follows:  Up to 75% of any individual exterior wall, including accessory structures, may be constructed of these materials for walls that do not abut a street or public right-of-way. Architectural accent materials, such as prefinished metal or wood, shall be allowed as exterior finishes for all buildings, provided that no more than 25% of any individual exterior wall shall consist of this material b. Prohibited Exterior Materials. The following materials shall not be allowed as exterior finishes for all buildings: Unadorned pre-stressed concrete panels; non-decorative concrete block; sheet metal; plywood; reflective or mirrored glass; corrugated or unfinished metal (except copper or other metal specifically engineered for exterior architectural use); aluminum siding or vinyl siding. c. Long Walls. No wall shall exceed 100 feet in length without visual relief, defined as the incorporation of design features such as large doors, windows, horizontal and vertical patterns, contrasting materials, or varying wall depths. d. Use of Non-Listed Materials. The Zoning Administrator may permit an exterior surface material not identified in this Subsection, provided the material is a result of new technology and/or the material is equal to or better in quality, appearance, and durability than the permitted materials. The applicant must submit the manufacturer’s warranty of the non-listed material. This subsection does not intend to reduce the percentage of required materials. e. Colors. Building colors shall consist of subtle, neutral, muted colors, with low reflectance which complement the principal materials. Bright or primary colors should only be used as accents, occupying a maximum of 10% of building facades. This standard does not apply to murals or other approved public art.
