Along the streets specified on Map 4 (Curb Cut Restrictions) in Appendix E of this Chapter, no curb cuts for parking facilities or loading berths shall be permitted.

However, the City Planning Commission may, by authorization, permit a curb cut, on a street specified on Map 4, for parking facilities and loading berths on a zoning lot that does not have access or egress on another street, provided that such curb cut will not unduly inhibit surface traffic or result in conflict between pedestrian and vehicular circulation, and will result in a good overall site plan.
