1251.06 MIXED USE AND SHARED PARKING.
   A.    Collective off-street parking facilities for separate uses, except for those in the SF and TF Districts, may be provided if the total number of spaces so provided is not less than the sum of the separate requirements of each such use, and all regulations governing proximity of off-street parking spaces to the use served are adhered to. No parking space or portion thereof shall serve as a required space for more than one (1) use unless approved by the Board of Zoning Appeals.
   B.    When two (2) or more uses jointly provide off-street parking as provided above, the Board of Zoning Appeals may authorize a reduction in the total number of required off -street
parking spaces, provided their respective hours of operation do not overlap in the manner described in the Schedule of Off-Street Parking Requirements. Reduction of off-street parking shall be subject to the following conditions:
      1.    A parking plan shall be submitted for approval by the Board of Zoning Appeals which shall show the layout of proposed parking.
      2.    The property owners involved in the joint use of off-street parking facilities shall submit a legal agreement approved by the Law Director of the City guaranteeing that the off-street parking spaces shall be maintained so long as the use requiring off-street parking is in existence or unless the required parking is provided elsewhere in accordance with the provisions of this Chapter. Such instrument shall be filed with the Zoning Administrator.
