(a)        Bulk modifications on waterfront blocks

In all districts, the City Planning Commission may permit modification of any applicable yard, lot coverage, height and setback, and distance between buildings regulations, for a development on a zoning lot within a waterfront block, excluding any portion on a pier or new platform, provided the Commission finds that such modifications will not adversely affect access to light and air on surrounding waterfront public access areas, streets and properties; and

(1)        will result in a better site plan and a better relationship between the zoning lot and the adjacent streets, surrounding neighborhood, adjacent open areas and shoreline than would be possible through strict adherence to the regulations; or

(2)        are necessary to protect unique natural features such as rock outcroppings, significant grade changes or wetlands, or to accommodate existing buildings or other structures.

(b)        Reduction or waiver of parking requirements for accessory group parking facilities

For developments on zoning lots in the Transit Zone, the City Planning Commission may, in conjunction with an application for a bulk modification pursuant to paragraph (a) of this Section, reduce or waive the number of required accessory residential off-street parking spaces, including any spaces previously required for an existing building on the zoning lot, provided that the Commission finds that:

(1)        where the applicant is seeking a reduction of parking spaces required by Section 25-23 (Requirements Where Group Parking Facilities Are Provided), such reduction will facilitate the development, enlargement or preservation of income-restricted housing units. Such finding shall be made upon consultation with the Department of Housing Preservation and Development;

(2)        the anticipated rates of automobile ownership for residents of such development are minimal and that such reduction or waiver is warranted;

(3)        such reduction of parking spaces will not have undue adverse impacts on the residents, businesses or community facilities in the surrounding area; and

(4)        such reduction of parking spaces will result in a better site plan.

In determining the amount of parking spaces to reduce or waive, the Commission may take into account current automobile ownership patterns for an existing building containing residences on the zoning lot, as applicable.
