For developments or enlargements within the Grand Central Core Area, as shown on Map 2 (East Midtown Subdistrict and Subareas) in Appendix A of this Chapter, in addition to the provisions of Sections 81-30 (OFF-STREET PARKING AND OFF-STREET LOADING REGULATIONS), inclusive, and 81-44 (Curb Cut Restrictions), the following shall apply:

(a)        Loading berth provisions

For through lots, the required loading berth shall be arranged so as to permit head-in and head-out truck movements to and from the zoning lot.

However, the Commissioner of Buildings may waive such head-in and head-out requirements, provided that:

(1)        the zoning lot has frontage along a street where curb cuts accessing a loading berth are permitted, but there is no access to such zoning lot from the street due to the presence of:

(i)        a building existing on August 9, 2017, containing residences;

(ii)        a non-residential building existing on August 9, 2017, that is three or more stories in height; or

(iii)        a building designated as a landmark or considered a contributing building in an Historic District designated by the Landmarks Preservation Commission; or

(2)        there are subsurface conditions, ventilation requirements from below-grade infrastructure or other site planning constraints that would make accommodating such loading berths infeasible.

(b)        Curb cut provisions

The maximum width of any curb cut (including splays) shall be 15 feet for one-way traffic and 25 feet for two-way traffic. Curb cuts shall not be permitted on 47th Street between Park and Madison Avenues or on 45th Street between Depew Place and Madison Avenue.
