Map 2 (Special Ground Floor Use Regulations), in Appendix A of this Chapter, specifies locations where the special ground floor use regulations of this Section apply. Such regulations shall apply along the entire street frontage of the building, as indicated on Map 2.

Uses located on the ground floor level or within five feet of curb level, and within 30 feet of the street wall, shall be limited to commercial or community facility uses permitted by the underlying district. A building’s street frontage shall be allocated exclusively to such uses, except for lobby space. In no event shall the length of street frontage occupied by lobby space exceed, in total, 40 feet or 25 percent of the building’s total street frontage, whichever is less, except that the length of lobby frontage need not be less than 20 feet.
