Within the boundaries of Community District 6, Borough of Queens, for commercial or mixed use developments or enlargements on two or more zoning lots in more than one block, which zoning lots, as defined in Section 12-10, each have single fee ownership or equivalent ownership arrangements for all lots comprising the development or enlargement, which are contiguous or would be contiguous but for their separation by a street, and located partially in a C4-2 District, partially in a C4-2F District, the City Planning Commission may permit upon application:

(a)        reduction of the parking requirement of Section 36-21 (General Provisions) by an amount not to exceed 50 percent, provided that the Commission finds that the applicant has demonstrated that the proposed parking is sufficient for the uses proposed;

(b)        any closed and demapped air space above a street to be considered as a part of the development or enlargement and to be used for automobile ways, or for pedestrian ways, provided the Commission finds that:

(2)        each bridge adjoins zoning lots which are wholly within the development or enlargement;

(3)        the curb levels of the adjoining zoning lots are not affected by the closing and demapping of such air space;

(d)        modification of applicable bulk regulations by permitting the total permitted floor area for all zoning lots within such development or enlargement to be distributed without regard to zoning lot lines and permitting the location of buildings without regard for the applicable height and setback regulations, provided the Commission finds that:

(1)        such distribution of floor area and location of buildings will result in better site planning and will thus benefit both the neighborhood and the City as a whole; and

(2)        such distribution of floor area and location of buildings will permit adequate access of light and air to surrounding streets and properties; and
