Opaque, highly tinted, or reflective glass is prohibited. Transparency into the building shall be maintained. Any window signs shall consist of individual letters and numerals without the use of any background.
c. Security bars, if installed, shall be on the inside of windows. Roll-up or accordion security grilles are permitted on the ground floor when constructed of a see-through, non-solid material. The Casing shall be painted to match the building and shall not damage or obscure architectural detailing.
d. Plain mansard roofs are prohibited. Decorative mansard roofs are permitted on buildings with a minimum wall height of two (2) stories. (See Figure 15-2: Examples of Decorative Mansard Roofs).
e. Decorative elements having historically functional purposes, such as shutters, balconies, windows, and doors, shall be operational.

i. Secondary access points are encouraged from rear parking lots. Facades that abut parking areas and contain a public entrance shall include pedestrian walkways.
j. When a shopping center is located behind a parking lot, a street presence for the shopping center shall be created by locating part of the center and/or outlot buildings near the lot line at the primary street corner or the shopping center entrance. When the center’s frontage on the primary street exceeds two-hundred fifty (250) feet in width, part of the center and/or outlot buildings shall hold at least fifty percent (50%) of the front lot line. (See Figure 15-3: Building Siting).

2. The following standards shall apply to all sites that meet the applicability thresholds of Section 4.5 Development Plan and Design Review:

c. Shopping centers with frontage on the primary street that exceeds two-hundred fifty (250) feet in width and a lot depth of three-hundred (300) feet or more are encouraged to construct an access road with parallel parking along that primary street. If an access road is constructed, retail storefronts shall be oriented to this access road.
d. Structures shall use decorative roof elements, such as projecting cornices, to define public entrances, main pedestrian routes or activity areas.
e. When visible from the public right-of-way (excluding alleys), façades shall include architectural features to avoid the appearance of blank walls facing the street. These include, but are not limited to, changes in the wall plane of at least six (6) inches, changes in wall texture or masonry patterns, colonnade, columns, or pilasters.
