Omaha Municipal Code § 55-935 Building design guidelines.

Sec. 55-935. - Building design guidelines. (a) Findings. The city council finds that the creation of high quality building design within the city is a major goal of the urban design element of the city's comprehensive plan, and further finds that the adoption of guidelines regarding the elevations of such buildings will help to achieve this goal. (b) Purpose. The purpose of these guidelines is to improve the quality of building design within the city and improve the city's image as defined by its built environment. While these guidelines attempt to set forth what is generally acceptable building design, the city intends by these guidelines to encourage innovation and creativity in the design of such buildings. (c) Definitions. For the purposes of the guidelines set forth in this section 55-935, the following words and phrases shall have the meanings respectively ascribed to them: Advertising sign: A sign describing specific products or brands offered for sale on premises. Business ID sign: Identification of a business or facility including name, logotype or tagline. Customer entrance: That part of a large retail building's exterior accommodating either access into or egress out of that building, or both access and egress, for customers of the retail establishment(s) located in the building. Directional sign: Indicates specific access points or entry ways, traffic directional information, etc. Elevation: The complete facade located on any side of a building. General building: All buildings NOT classified as large retail buildings. Large retail building: Any building used primarily for retail uses and having at least one elevation greater than 200 feet in length and/or a floor area greater than 25,000 square feet. Secondary sign: A sign not categorized as business identification or directional which are considered primary building and site signs. Secondary signs generally include operational, departmental or other characteristics of the facility/building. Visible elevation: Any elevation of a building which is visible from a public right-of-way adjacent to the property on which the building is located or from a parking lot within such property. (d) Guidelines. Buildings will be reviewed comprehensively against all provisions of this section for the determination of design quality. The following review criteria apply to buildings pursuant to section 55-935, unless provided for otherwise: (1) Wall materials. a. General standard. All building elevations should be composed of either primary, complementary and/or miscellaneous materials described in this section. Approved primary material(s) should be used as the prominent wall material. The use and location of primary material(s) may be prioritized towards pedestrian environments and/or the base of multi-storied buildings. Approved complementary materials should be used in a manner to complement primary materials in terms of use and location. Approval of appropriate use and location of wall materials will include consideration of building massing, height, building location, proximity to public/pedestrian environments, context; visibility and three dimensional aspects of the design. The quality of building elevation design per subsection 55-935(d)(2) and design of the building as a whole should be emphasized rather than the quantity of any one wall material proposed. b. Miscellaneous materials. Miscellaneous exterior materials such as trim, coping, flashing, canopies, louvers and or design accents should be compatible with the overall building quality and design. Materials not listed as an approved material described in Table 55-935(1) may be considered a miscellaneous material. c. Grades of materials. For a material and/or assembly of materials to be considered similar in grade to an approved material described in Table 55-935(1) it shall be required to achieve two primary attributes: 1. Durability. Durability of materials shall be defined as its performance by virtue of its ability to resist stress, force or degradation over time. 2. Appearance. Appearance of materials shall be defined as its physical characteristics of size, shape, texture, grain, coloring and/or material composition as perceived visually. Supporting evidence for a wall material proposed as similar in grade to an approved material listed in Table 55-935(1) shall be provided to the planning department for approval by the applicant concurrent with the urban design site plan review process. In the event that the applicant is aggrieved by a judgment concerning similarity of grade, the applicant or the planning director may request a recommendation by the urban design review board as described in section 55-937 concerning urban design site plan approval. d. Applicability. Wall material requirements shall apply to all buildings pursuant to section 55-935 with the following exceptions. 1. Residential use only buildings with four or fewer dwelling units within ACI-3, ACI-4, IG and MCC zoning districts and not part of a larger integrated development. 2. Residential use only buildings with two or fewer dwelling units within TOD, ACI-1, ACI-2, CP and MU districts and not part of a larger integrated development. TABLE 55-935(1)—WALL MATERIALS Building Design Guidelines—Wall Materials Primary Materials (see note 1) | Complementary Materials Natural or Cast Stone | Concrete Masonry Units, Integral Finish/Texture (see note 2) Brick | Concrete Masonry Units, Non-integral Finish/Texture (see note 3) Glazing/Curtain Wall | Cementitious Panels Architectural Grade Metal Panel or Metal Cladding | EIFS/Stucco (see note 4) Architectural Grade Precast Concrete | Corrugated Sheet Metal Siding (see note 5) Other Similar Grade Materials | Architectural Grade Vinyl Siding (see note 6) Other Similar Grade Materials 1. Industrial/agricultural grade wall systems or other similar grade materials are prohibited as a primary material. 2. May be used as a primary material on large retail buildings. 3. May be used as complementary material on large retail buildings or non-visible elevations of general buildings only. 4. When EIFS is used, it generally should be placed a minimum of eight feet above grade and be applied in an articulated fashion. The placement of EIFS may be varied so as to average a minimum of eight feet above grade, but in no case shall it be placed closer than three feet above grade unless specified as impact resistant and includes an additional layer of 20 oz. mesh. 5. Corrugated sheet metal siding may be used as a complementary material provided it is specified as a concealed fastener system. A non-concealed fastener system may be used as a miscellaneous material in limited application and is subject to approval. 6. Vinyl siding may only be used on residential use only buildings as a complementary material and must be specified to be .050 inches thick or greater. (2) Design of elevations. a. Continuity of design. All visible elevations of proposed buildings shall be consistent in design and use of materials. b. Articulation of the facade. All facades shall be designed in three dimensions expressing qualities of depth, shadow, modulation and massing. Extensive undifferentiated wall planes that are flat, two-dimensional and are not allowed unless part of an overall design scheme approved by the planning director. c. Proportion of height to length of elevations. Buildings that are only one story and have walls longer than 100 feet should be designed so that the height of the wall, including the parapet, if there is one, averages not less than one-tenth of the length of the wall. In the case of walls longer than 300 feet, this provision can be satisfied by providing architectural elements at the ends of the wall that meet the height criteria for the entire length of the wall, but the rest of the wall need not be taller than 30 feet. d. Mitigating the effect of long elevations. Building elevations should utilize design elements proportionate to the human scale. Arcades, colonnades, awnings, pilasters, windows, plazas, landscaping, lighting and galleries are all useful devices to achieve a human scale. Varying the use of different materials, use of expression lines and/or dividing materials by color, texture and pattern is also an effective method. Elements of scale may be prioritized by degree of proximity to pedestrian environments. e. Incorporating canopies into the design. Where weather protection is extended out over a sidewalk or traffic lane as a canopy at a building entrance, the canopy should be incorporated into the design of the entrance pavilion or otherwise incorporated into the architectural design of the building. f. Base of buildings. Where pedestrian activity occurs at the base of visible facades, the building should be designed such that it does not significantly disrupt or diminish the quality of the pedestrian area. If parking occupies the ground level, it should be fully enclosed and the wall finishes should be comparable to those used in the inhabited portion of the building. Exterior mechanical equipment, such as an exhaust ventilator, should be located not less than ten feet above the base of the building. (3) Proportion and visibility of entrances. Entrances in visible elevations of buildings will be reviewed according to the following criteria. a. Entrances should be part of an architectural composition that is in scale with the entire visible elevation in which it is contained. The location of entrances should be legible and all public pedestrian entrances should be accessible from sidewalks that connect to the public sidewalk system. Where there are many entrances to separate establishments, a continuous band of doors and windows along the entire visible elevation is a customary design approach. Where doors are not part of such a continuous band, the doors should be part of an entrance pavilion, projection, or comparable architectural element that incorporates the doors, and is in scale with the length and height of the whole elevation. b. Buildings with two or more "sidewalk adjacent facades" as defined in section 55-926 shall provide a minimum of one entrance within a sidewalk adjacent facade. This requirement may be satisfied with a corner entrance. c. When there is a large retail building and other, smaller stores which are part of the same development, the smaller stores, with their separate entrances, may be placed in front of the large retail building, or along one of its sides, in order to mitigate the scale of the large building. d. Where a large retail building entrance elevation is longer than 200 feet there should be more than one customer entrance to provide convenient access from multiple approaches to the building. Entrances shall be separated a minimum distance equaling 25 percent the length of the entrance elevation. Access to an interior or exterior arcade shall be considered an acceptable means for providing a building entrance. (4) Proportion and organization of windows. The following guidelines apply to windows on visible elevations of buildings: a. Windows should be in scale with the entire elevation of which they are a part. b. Windows should be part of a design and proportional system that extends to the entire visible elevation. Examples of such a system would be uniform sill and window heights, or continuous horizontal or vertical bands of windows. Windows that appear as individual openings in a masonry wall should be placed in accordance with a proportional system that can be explained by a drawing, although the system need not be expressed in the wall itself. c. Where a building has an elevation with a primary (front) entrance adjacent to a parking lot, the ground-level transparency standards of subsection 55-926(a) shall apply to that elevation. d. All buildings shall follow the transparency requirements set forth in section 55-926, except as follows: 1. For large retail buildings the minimum required transparency within the zone of transparency is 20 percent. 2. The minimum transparent area as delineated in subsection 55-926(a) may be reduced to 20 percent when a large retail building utilizes an arcade in combination with features that add visual interest to the wall. The arcade must be designed as a recess within the primary wall plane. Arcade openings in the wall plane must have the proportion and general appearance of door and window openings. (5) Relating buildings to sloping sites. Grading plans including one or more buildings should minimize the necessity for retaining walls and preserve the natural integrity of the site topography as much as possible. Parking lots should be designed to absorb changes of grade through gentle slopes and low retaining walls within the parking area, rather than accumulating all grade changes at the site perimeter. Where the height of a building elevation changes appreciably across a site, the design should take these circumstances into account. (6) Building signs. In addition to the building sign standards set forth at sections 55-821 through 55-847, the following review criteria shall apply to signs for all buildings and sites: a. Signs on visible elevations should be limited to identification of the commercial business or businesses within the building. Where signs are associated with the entrance to the commercial business the size of the sign should be in proportion to the entrance. Where the sign is placed away from the entrance or on a wall that does not have an entrance, the sign should be integrated with the design of the wall through such devices as placing the letters of the sign directly on the wall so that the wall can be seen between the lettering. b. Where there are multiple establishments in the same building, there should be a sign plan to ensure continuity of the identification signs of all the establishments in the building. c. Secondary signs may be used on no more than two elevations. Signs shall not exceed five percent the length of any two elevations respectively and shall not exceed ten percent when used on one elevation. Secondary signs shall not exceed two feet in height. (7) Screening of equipment and utility areas. a. Screening of rooftop equipment. Mechanical equipment above the surface of the roof, such as cooling towers, vent fans and vent stacks, should be screened by architectural elements such as a parapet extending upward from the perimeter wall or an architectural roof-top enclosure so that the equipment is not casually visible from adjacent public streets or from the parking lot for the building. In no case shall the parapet wall or roof top enclosure be required to exceed the height of the mechanical equipment. All screening material shall be comparable in design and quality of materials to the facades of the building itself. b. Screening of exterior mechanical equipment. All mechanical equipment located outside a building, such as transformers or condensers, should not be easily visible to the public from streets or parking lots. Such elements should be screened, to the extent allowed by the public utility, by locating them within a perimeter wall of comparable design and materials to the building's visible elevations and sufficiently high as to completely conceal the equipment. Landscaping used as a screen should utilize evergreens sufficiently tall, densely planted, and well maintained. c. Screening of loading docks and service operations. Loading and service operations including storage of waste materials, should not be visible to the public from streets or parking lots. An effective way to screen such elements is to locate them within the building perimeter, screened by doors. Doors to loading docks should not be open except when vehicles are actually entering or leaving the building. Landscaping used as a screen should utilize evergreens, sufficiently tall, densely planted, and properly maintained. (8) Parking lot setbacks and sidewalks. Where a building has an elevation with a primary (front) entrance adjacent to a parking lot, the following minimum parking lot set-backs and sidewalk widths per Table 55-935(2) shall apply. TABLE 55-935(2)—MINIMUM PARKING LOT SET-BACKS AND SIDEWALK WIDTHS Min. Set-back Width | Min.
