Within the Special Hudson Yards District, except within C1-7A Districts, or C2-5 Districts mapped within R8A Districts, for developments or enlargements on zoning lots with at least 20,000 square feet of lot area or developments or enlargements on any size zoning lot that occupy the entire block front along a wide street, the City Planning Commission may modify the regulations set forth in Sections 93-40 (HEIGHT AND SETBACK REGULATIONS), inclusive, and 93-50 (SPECIAL HEIGHT AND SETBACK REGULATIONS), inclusive, provided the Commission finds that:

(a)        such modifications will result in a better distribution of bulk on the zoning lot and will not adversely affect access to light and air for surrounding public access areas, streets and properties;

(b)        where the development or enlargement is subject to the requirements of Sections 93-60 (MANDATORY IMPROVEMENTS), inclusive, or 93-70 (PUBLIC ACCESS REQUIREMENTS FOR SPECIAL SITES), inclusive, such modifications will not impair the quality of such public access areas on the zoning lot;

(c)        such modifications are consistent with the goal of the special district to provide flexibility of architectural design and encourage more attractive building forms; and

(d)        such modifications will result in a development or enlargement that enhances the streetscape and will be compatible with development in the surrounding area.

The Commission may prescribe additional conditions and safeguards to minimize adverse effects of the development or enlargement on the character of the surrounding area.
