(a)        Hudson Boulevard

For the purposes of this paragraph (a), Hudson Boulevard shall be considered to be a wide street. The street wall of buildings shall be located on the Hudson Boulevard sidewalk widening line and extend along at least 70 percent of the length of the Hudson Boulevard frontage of the zoning lot, and shall rise without setback to a minimum base height of 90 feet and a maximum base height of 120 feet. On corner lots, the maximum base height may apply along intersecting narrow street lines for a distance of 100 feet from its intersection with Hudson Boulevard. Above a height of 120 feet, a setback at least 25 feet in depth is required from the Hudson Boulevard street line, and setbacks from intersecting narrow streets shall comply with the provisions of paragraph (b) of Section 93-42 (Height and Setback in Subdistricts A, B, C, D, E and F).

Alternatively, for zoning lots that occupy the entire Hudson Boulevard block front, the Hudson Boulevard street wall may rise above a height of 120 feet without setback at the Hudson Boulevard sidewalk widening line, provided that:

(1)        the aggregate width of such street wall facing Hudson Boulevard does not exceed 100 feet;

(2)        all other portions of the building that exceed a height of 120 feet are set back at least 25 feet from the Hudson Boulevard street line at a height not lower than 90 feet; and

(3)        all portions of the building that exceed a height of 120 feet are set back from a narrow street in compliance with the provisions of paragraph (b) of Section 93-42.

(b)        Tenth Avenue

The street wall of buildings shall be located within 10 feet of the Tenth Avenue street line and extend along at least 70 percent of the Tenth Avenue frontage of the zoning lot, and shall rise without setback to a minimum base height of 90 feet and a maximum base height of 150 feet. On corner lots, the maximum base height may apply along intersecting narrow street lines for a distance of 100 feet from its intersection with Tenth Avenue. Above a height of 150 feet, the setback provisions of paragraph (b) of Section 93-42 shall apply.

Alternatively, for zoning lots that occupy the entire Tenth Avenue block front and where no portion of the building is within 10 feet of the Tenth Avenue street line, the Tenth Avenue street wall may rise above a height of 150 feet without setback, provided:

(1)        the aggregate width of such street wall does not exceed 100 feet;

(2)        all other portions of the building that exceed a height of 150 feet are set back at least 10 feet from the Tenth Avenue street wall of the building at a height not lower than 90 feet; and

(3)        all portions of the building that exceed a height of 150 feet are set back from a narrow street in compliance with the provisions of paragraph (b) of Section 93-42.

(c)        Midblocks

For all zoning lots with frontage along the northerly street lines of West 35th through West 40th Streets, the street wall of any building shall be located on and extend along at least 50 percent of the length of the sidewalk widening line of the zoning lot and shall rise without setback to a minimum base height of 60 feet and a maximum base height of 120 feet. Above a height of 120 feet, the setback provisions of paragraph (b) of Section 93-42 shall apply. Alternatively, the street wall of a building may rise without setback at the sidewalk widening line provided the aggregate width of such street wall does not exceed 100 feet or 50 percent of the width of such northerly street line frontage of the zoning lot, whichever is less, and provided all other portions of the building that exceed a height of 120 feet comply with the setback provisions of Section 93-42. The provisions of this paragraph shall not apply within 100 feet of Eleventh Avenue. However, any zoning lot partially within 100 feet of Eleventh Avenue may, as an alternative, apply the provisions of this paragraph (c) to the entire West 35th, West 36th, West 37th, West 38th, West 39th or West 40th Street street frontage of the zoning lot.

For all zoning lots with frontage along the southerly street lines of West 36th through West 41st Streets, the street wall of any building shall not exceed a maximum base height of 120 feet. Above a height of 120 feet, the setback provisions of paragraph (b) of Section 93-42 shall apply.
