(1)        For zoning lots that do not occupy the entire Tenth Avenue block front, and for zoning lots that occupy the entire Tenth Avenue block front where existing buildings containing residences will remain, the street wall of any development or enlargement shall be located on and extend along the entire Tenth Avenue street line, except that to allow for corner articulation, the street wall may be located anywhere within an area bounded by intersecting street lines and lines 15 feet from and parallel to such lines. Such street wall shall rise without setback to a minimum base height of 90 feet and a maximum base height of 150 feet, except that such minimum base height requirement shall not apply to any existing buildings containing residences to remain. Where such zoning lots also front upon a narrow street, these provisions shall apply along such narrow street frontage for a minimum distance of 50 feet and a maximum distance of 100 feet from the intersection of Tenth Avenue. Above a height of 150 feet, the setback provisions of paragraph (b) of Section 93-42 shall apply.

These provisions shall apply for a minimum distance of 50 feet and a maximum distance of 100 feet from the intersection of Tenth Avenue.

Above a height of 150 feet, the setback provisions of paragraph (b) of Section 93-42 shall apply. Alternatively, the Tenth Avenue street wall may rise above 150 feet without setback, provided that:

(ii)        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;

(iii)        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; and

(iv)        all portions of the Tenth Avenue street wall that do not exceed a height of 90 feet are located 10 feet from the Tenth Avenue street line, except that recesses may be provided in accordance with the recess provisions of paragraph (a) of Section 93-50. Above a height of 90 feet, up to a height of 150 feet, any street wall facing Tenth Avenue shall be located no closer to Tenth Avenue than 10 feet.

The maximum length of any story located above a height of 150 feet that faces north or south shall not exceed 100 feet.
