If, in the course of its site development plan review, the approving authority determines that by reason of the proposed use of particular premises, or for any other reason, the number of parking spaces which will be required to meet the parking needs of such premises is less than the number of spaces which would otherwise be required under this chapter, the approving authority shall have the power to permit the applicant to construct and pave only such number of parking spaces as the approving authority determines to be necessary to meet such requirements and to permit the remaining area, which would otherwise be required to be constructed and paved for parking purposes, to remain unpaved in a landscaped condition; provided, however, that the site development plan shall delineate the full number of parking spaces which, but for such finding of the approving authority, would be required, and any certificate of occupancy issued for such premises shall note the decision of the approving authority as described herein, and provided further that the Zoning Officer shall, from time to time, inspect said premises to determine the adequacy of existing parking spaces and report thereon to the approving authority, and the approving authority shall have the power, at any time that it determines that construction and paving of the remaining parking area is necessary in order to satisfy the parking requirements of the premises, to order such additional construction and paving. In the event that there is a transfer of ownership of the premises or a change in its use, or if said premises are leased to a tenant other than as set forth in the original certificate of occupancy, or should the holder of the certificate of occupancy, either as owner or tenant, increase the use beyond which the certificate of occupancy was issued, the approving authority shall have the power at that time to request additional site plans for presentation in order to determine whether the parking requirement shall be increased or decreased.
