When a large-scale community facility development includes two or more zoning lots which are contiguous or would be contiguous but for their separation by a street, the City Planning Commission may, in appropriate cases, upon application, authorize the permitted floor area, lot coverage, dwelling units or rooming units, or the required open space for all zoning lots within the large-scale community facility development, to be distributed without regard for zoning lot lines, may modify the minimum required distance between buildings as set forth in Section 23-70 (MINIMUM REQUIRED DISTANCE BETWEEN TWO OR MORE BUILDINGS ON A SINGLE ZONING LOT), provided such reduction does not exceed 15 percent of that required by Section 23-71, may authorize the location of buildings without regard for front yard or height and setback regulation which would otherwise apply along portions of streets wholly within the large-scale community facility development and, further, may authorize the location of community facility buildings without regard to side or rear yard regulations which would otherwise apply along portions of lot lines abutting other zoning lots within the large-scale community facility development.

As a condition of granting such authorizations, in each case the Commission shall make the following special findings:

(a)        that such distribution or location will permit better site planning and will thus benefit both the residents, occupants or users of the large-scale community facility development and the City as a whole;

(b)        that such distribution or location will not unduly increase the bulk of buildings in any block, to the detriment of the occupants or users of buildings in the block or nearby blocks; and

(c)        that such distribution or location will not affect adversely any other zoning lots outside the large-scale community facility development by restricting access to light and air or by creating traffic congestion.

In R9, R10, C1-8, C1-9, C2-7 or C2-8 Districts, or in C1 or C2 Districts mapped within R9 or R10 Districts, floor area bonuses for public plazas or arcades permitted in accordance with the applicable district regulations shall apply only to a development or enlargement with 25 percent or less of the total floor area of the building in residential use.

In R9, R10, C1-8, C1-9, C2-7 or C2-8 Districts, or in C1 or C2 Districts mapped within R9 or R10 Districts, no existing publicly accessible open area, arcade or other public amenity, open or enclosed, for which a floor area bonus has been received pursuant to regulations prior to February 9, 1994, shall be eliminated or reduced in size except by special permit, pursuant to Section 74-761 (Elimination or reduction in size of bonused public amenities).
