§ 27A-404. Storefront Building Envelope Standards.

(a)

Intent and Illustrations.

The Storefront Building Envelope Standard is a variation on the General Building Envelope Standard. The uses for Storefront are highly skewed toward retail. The primary feature is that of Storefronts placed directly up and into the sidewalk. This frontage type is ideal for lining large footprint buildings, whether the structure is an office building, "big-box retail", or a parking garage. It visually breaks the Façade into smaller pedestrian-scaled sections and can activate an entire Block length through multiple smaller retail uses (and entrances).

(b)
