§ 151.1509  SITE LAYOUT AND BUILDING CONFIGURATION.
   (A)   General site layout. Along Montgomery Road and Main Street frontages, the general site layout shall conform to the following standards.
      (1)   A minimum of 60% of a development’s frontage on either Montgomery Road or Main Street must be occupied by building frontage, and an additional 10% may be occupied by building frontage or a site wall as specified below, which is located no further than ten feet from the front property line. The site wall shall be an extension of the principal or accessory building(s). The city may allow up to 50% of a building’s surface to be setback between ten and 20 feet from the right-of-way to create facade articulation. Of that 50%, the building’s surface may be setback farther than 20 feet provided that a plaza, raised terrace, balcony or another useful outdoor pedestrian space is incorporated along the frontage.
      (2)   On panhandle lots, the building may be setback more than ten feet from the public right-of-way when the lot has less than 25 feet of frontage along Montgomery Road or Main Street. The building must setback a minimum of 20 feet from the rear property line of the parcel in front of the panhandle lot.
      (3)   Site walls (including wing walls, retaining walls or screen walls attached to the building) shall be constructed of solid masonry and shall have a height not less than three feet nor greater than eight feet, not including ornamentation or other features.
      (4)   The remaining 30% of a development’s frontage on either Montgomery Road or Main Street may be used for necessary vehicle and pedestrian access ways, or public use space.
   (B)   Parking.  Parking lots or parking structures shall be regulated as follows:
      (1)   Parking lots shall meet the setback standards as established in § 151.1207.
      (2)   Freestanding above-grade parking structures shall not be located in the front yard and shall meet the side and rear project boundary setbacks established for buildings in § 151.1508.
      (3)   Below grade parking structures, which are part of a building’s foundation, may be permitted to project above grade. Whenever a below-grade parking structure is constructed such that a portion of the garage extends above finished grade, no more than 50% of the footprint shall extend more than five feet above grade. For purposes of this section, above-grade garage walls, which are shielded from view by a building shall be considered as less than five feet in height. Any portion off a below-grade garage that projects above finished grade, which is visible from the right-of-way and not screened by a building, must have the structural components clad in a permitted primary building material as defined in § 151.1515(a)(1). The Planning Commission may also require additional architectural detail and/or landscaping that creates a pedestrian friendly streetscape.
      (4)   Parking lots and parking structures shall be buffered or screened at a minimum as required, per § 151.3408.
   (C)   In multi-building developments, a parking lot may be located between a rear building and a building fronting on Montgomery Road or Main Street.
   (D)   Building coverage. Building coverage in the OMG shall be regulated as follows:
      (1)   Single building developments. A single building fronting on Montgomery Road or Main Street shall not have a footprint which exceeds 15,000 square feet.
      (2)   Panhandle lots. Any building on a panhandle lot with less than 25 feet of frontage along Montgomery Road or Main Street shall be treated as a rear building for coverage purposes.
      (3)   Multiple building development. When included in a multiple-building development on a site in excess of two acres, a single building may have a footprint of up to 17,500 square feet. A building with a footprint in excess of 17,500 square feet shall be permitted under the following conditions:
         (a)   When a building is located south of Hartfield Place and within 200 feet of Montgomery Road, the building footprint shall not exceed 20,000 square feet;
         (b)   When the majority of the building footprint is located more than 200 feet from Montgomery Road or Main Street with no building frontage on Montgomery Road or Main Street, the building may be permitted to have a footprint of up to 30,000 square feet;
         (c)   When a building located within 200 feet of Montgomery Road or Main Street has a lineal frontage along Montgomery Road or Main Street of 100 feet or less, the building may be permitted to have a footprint of up to 19,000 square feet;
         (d)   Under no circumstances may a building’s footprint exceed 30,000 square feet;
         (e)   Adequate parking for the building’s use as specified in § 151.3204 can be accommodated in whole or in part in on-site structured parking, which is integrated into the development design;
         (f)   Off-street loading areas are provided for the building in accordance with § 151.3211;
         (g)   The building and required parking are screened from the public right-of- way by smaller buildings that address the street and meet the minimum setback and the standards of § 151.1508;
         (h)   The loading, parking, and trash dumpsters are adequately screened from adjacent residential uses; and
         (i)   The building meets all other building design standards as specified by this chapter.
   (E)   Loading and service areas. Loading and service areas shall be located and designed in such a way as to minimize visual and noise impact on adjacent residential uses. The use of solid walls and buffer landscaping are encouraged to reduce the visual and noise impact of loading and service areas from adjacent rights-of-way and residential areas.
