SEC. 51A-4.605.   DESIGN STANDARDS.
   (a)   Design standards for large retail uses.
      (1)   Purpose.  Large retail uses often have negative impacts on community aesthetics, the environment, mass transit, pedestrian circulation, the scale and rhythm of streetscapes, traffic, and urban sprawl. These design standards are intended to ensure that large retail uses are compatible with the surrounding area and mitigate the negative impact of large retail uses while allowing creativity, flexibility, and variety in design. These design standards are also intended to make adaptive reuse of large retail spaces possible.
      (2)   Applicability.
         (A)   These design standards apply to the following uses built after October 27, 2004, and the following existing uses expanded to 100,000 square feet or more:
            (i)   In Chapter 51:
               (aa)   Retail stores other than listed uses of 100,000 square feet or more.
               (bb)   Retail food store uses of 100,000 square feet or more.
               (cc)   Furniture store uses of 100,000 square feet or more.
               (dd)   Home improvement center uses of 100,000 square feet or more.
            (ii)   In Chapter 51A:
               (aa)   Furniture store uses of 100,000 square feet or more.
               (bb)   General merchandise and food store uses of 100,000 square feet or more.
               (cc)   Home improvement center, lumber, brick or building material sales yard uses of 100,000 square feet or more.
         (B)   These design standards do not apply to a covered mall building containing more than 500,000 square feet. These design standards do apply to any use listed in Subparagraph (A) within a covered mall building (an anchor tenant) that has a means of ingress and egress independent of the covered mall building and does not have an entrance into the common pedestrian area.
         (C)   The landscape requirements of these design standards may be used to satisfy any landscaping required by Article X.
         (D)   In the event that these design standards conflict with other requirements of this chapter, the more stringent requirement applies.
      (3)   Definitions.  The following definitions apply to these design standards:
         (A)   COVERED MALL BUILDING means a single building enclosing 10 or more retail, personal service, and office uses that have access into a climate-controlled common pedestrian area.
         (B)   FACADE WALL means any separate face of a building, including parapet walls and omitted wall lines, or any part of a building that encloses usable space. Where separate faces are oriented in the same direction, or in the directions within 45 degrees of one another, they are considered as part of a single facade wall.
         (C)   FRONT PARKING AREA means, for developments with a single use, the area in front of a line parallel to and extending outward from the primary facade wall to the property lines, and means, for developments with multiple uses, the area between two lines at the corners of the primary facade wall and perpendicular to the primary facade wall and extending to the property line.
         (D)   PRIMARY FACADE WALL means the facade wall containing the primary entrance. If two or more facades walls have entrances of equal significance, each facade wall will be considered a primary facade wall.
         (E)   REAR FACADE WALL means the facade wall containing service areas.
         (F)   SIDE FACADE WALL means any facade wall that is not a primary facade wall or a rear facade wall.
         (G)   SERVICE AREA means any area for loading docks, outdoor storage (other than an outdoor display, sales, and storage area), trash collection or compaction, truck parking, or other similar functions.
      (4)   Facade walls. Primary facade walls and side facade walls must incorporate at least three of the following design elements. Rear facade walls must incorporate at least two of the following design elements. The cumulative length of these design elements must extend for at least 60 percent of the facade wall’s horizontal length.
         (A)   A repeating pattern of wall recesses and projections, such as bays, offsets, reveals, or projecting ribs, that have a relief of at least eight inches.
         (B)   At least three of the following design elements at the primary entrance, so that the primary entrance is architecturally prominent and clearly visible from the abutting street:

         (E)   Trim or accent elements using decorative contrasting colors or decorative neon lighting of at least 10 percent of the area of the facade wall exclusive of fenestration.
      (5)   Facade wall changes.  Facade walls must have a one or more of the following changes:
         (A)   Changes of color, texture, or material, either diagonally, horizontally, or vertically, at intervals of not less than 20 feet and not more than 100 feet.

         (E)   Outdoor display, sales, and storage areas, such as nursery departments, must be enclosed by screening with a solid base with a minimum height of three feet surmounted by a wrought iron or tubular steel fence with a minimum height of five feet. The screening must be surmounted with a minimum of two feet of fascia with materials and colors matching the main building. No merchandise other than trees may be visible above the screening.
         (F)   Shopping cart storage areas adjacent to facade walls (not in parking lots) must be screened with landscaping or materials matching the materials of the primary facade wall. No more than two shopping cart storage areas (one on each side of an entrance) may be provided on any facade wall. Shopping cart storage areas may not exceed 20 feet in length.

      (10)   Variations and exceptions.  The city plan commission, whether or not a specific use permit is required, may approve a site plan that does not comply with the requirements of these design standards provided that:
         (A)   strict compliance with these design standards is impractical due to site constraints or would result in substantial hardship;
         (B)   the site plan complies with the spirit and intent of these design standards;
         (C)   the site plan furthers the stated purpose of these design standards; and
         (D)   the variation or exception from these design standards will not adversely affect surrounding properties.
The city plan commission shall follow the same procedure used for approval of minor amendments to development plans and the fee for a minor plan amendment shall apply.  (Ord. Nos. 25785; 27404; 28553; 31607)
