With these connections, commercial site plans are exempt from the landscaping requirements of section 24-4(a)(2).

    2.

    Developments that use shared driveways between adjacent parcels may be permitted to reduce fifteen (15) percent of the total off-street parking required on both parcels as specified in section 38-1476. This incentive may not be combined with any other off-street parking reduction specified in this section.

    3.

    Consistent with the intent of this section, access management shall not be pursued using street closures or cul-de-sacs.

    To encourage the development of mixed uses within buildings, the parking requirements of section 38-1476 shall be reduced by twenty (20) percent for buildings containing a mix of commercial, office, and residential uses, provided the building has at least twenty (20) percent of each use represented as a principal use and that the commercial use does not occupy more than sixty-five (65) percent of the gross floor area of the building. This incentive may not be combined with any other off-street parking reduction specified in this section.
