The City Planning Commission may permit group parking facilities accessory to uses in large-scale residential developments or large-scale community facility developments or large-scale general developments with more than the prescribed maximum number of parking spaces set forth in Sections 25-12, 36-12 and 44-12 (Maximum Size of Accessory Group Parking Facilities) or may permit modifications of the applicable provisions of Sections 25-11, 36-11 and 44-11 (General Provisions) so as to permit off-street parking spaces accessory to such uses to be located on the roof of a building.

As a condition of permitting such exceptions or modifications, the Commission shall make the following findings:

(a)        that such use is so located as to draw a minimum of vehicular traffic to and through local streets in residential areas;

(b)        that such use has adequate reservoir space at the vehicular entrance to accommodate either 10 automobiles or five percent of the total parking spaces provided by the use, whichever amount is greater, but in no event shall such reservoir space be required for more than 50 automobiles;

(c)        that the streets providing access to such use will be adequate to handle the traffic generated thereby; and

(d)        that where roof parking is permitted, such roof parking is so located as not to impair the essential character or future use or development.

The Commission may prescribe appropriate conditions and safeguards to minimize adverse effects on the character of the surrounding area including requirements for shielding of floodlights, for locations of entrances and exits, or for setback of any roof parking areas from lot lines.

This Section shall not apply to the Manhattan Core where the regulations set forth in Article I, Chapter 3, shall apply, or to the Long Island City area, as defined in Section 16-02 (Definitions), where the regulations set forth in Article I, Chapter 6, shall apply.
