The City Planning Commission may permit a parking facility listed in paragraph (a) of Section 13-45 (Special Permits for Additional Parking Spaces), where such parking facility serves the parking needs of a non-residential use not otherwise listed in paragraph (a) of Section 13-452, provided that, in addition to the conditions and findings set forth in Section 13-45, the Commission shall find that:

(a)        the proposed parking facility is in close proximity to or on the same zoning lot as a commercial use, community facility use or manufacturing use that is of significant importance to the economic well-being of the City of New York;

(b)        an increased number of permitted off-street parking spaces in such proposed parking facility is essential to the operation of such use; and

(c)        reasonable measures to minimize parking demand have been identified. For existing or enlarged uses, such measures shall have been implemented, where feasible, prior to application, and a commitment by the applicant shall be made, in a form acceptable to the Commission, to continue and, where necessary, improve upon and supplement such measures. For new uses, such measures shall be committed to in a form acceptable to the Commission.

The Commission may prescribe appropriate conditions and safeguards to minimize adverse effects on the character of the surrounding area.
