Buildings within a shopping center shall be set back at least
50 feet from any adjoining residential use.

|
Within a main street setting, no less than 70% of a building's
front facade must be located on the front build-to line. Front build-to
lines shall be measured between the edges of street curb and the closest
facade of the building. No part of any building shall extend closer
to a street than the minimum front build-to line. The use of front
build-to lines delineate the public streetscape of a TND. On lots
where existing buildings are set back beyond the front build-to lines,
such buildings may be extended, or, in the alternative, thirty-six-inch-
to forty-two-inch-high walls shall be constructed within the required
build-to line to define the public streetscape. Also, uses with streetside
cafes may locate the front facade of their building beyond the front
build-to line, provided that the outdoor seating area features a permanent
barrier that is located within the required front build-to line. Any
variations in the vertical facade of storefronts shall be made at
intervals of up to 36 feet so that a typical storefront width is repeated
in any such building.

Off-street parking is prohibited within the front yard within
commercial courtyards and main street settings. Off-street parking
within a shopping center shall include a thirty-six-inch- to forty-two-inch-high
wall used to separate the parking lot from the sidewalk that is located
within the required front build-to line. No off-street parking lot
shall be located within the front yard at a street corner.

The maximum permitted lot coverage can be increased to a maximum of 75% through compliance with the architectural design standards as contained in § 155-21S of this chapter. Properties that achieve a maximum permitted lot coverage of 65% through the application of TDRs are also eligible to increase the permitted lot coverage to a maximum of 75% through compliance with the architectural design standards as contained in § 155-21S of this chapter.
