The regulations of this Section shall apply along Surf Avenue. The street wall location provisions of paragraph (a) of this Section shall also apply along streets intersecting Surf Avenue within 50 feet of Surf Avenue, and the building base regulations of paragraph (b) of this Section shall also apply along streets within 100 feet of Surf Avenue.

1. Street wall location
   
   The street wall location provisions of paragraph (a) Section 35-631 shall apply and extend up to minimum base heights as defined in this Section. To allow for portions of towers to rise without setback from grade, a portion of a building base below a tower may be set back 10 feet from a street line, provided the width of such setback area is not greater than 40 percent of the width of the street wall of the tower and provided such setback area complies with the provisions of Section 131-47 (Design Requirements for Ground Level Setbacks).
2. Building base
   
   The street wall of a building base fronting on Surf Avenue shall rise without setback to a minimum height of six stories or 65 feet, or the height of the building, whichever is less, and a maximum height of eight stories or 85 feet, whichever is less, before a setback is required. However, on the portion of the block bounded by Stillwell Avenue and West 15th Street, for buildings that exceed a height of 85 feet, all street walls of such building fronting on Surf Avenue shall rise without setback to a height of 85 feet.
   
   All portions of a building or other structure that exceed a height of 85 feet shall be set back from the street line at least 10 feet, and shall comply with the tower provisions of Section 131-444 (Coney North Subdistrict towers). Such setback may be modified in accordance with the provisions of Section 23-433 (Standard setback regulations).
3. Transition height
   
   Above the maximum base height, a street wall may rise to a maximum transition height of nine stories or 95 feet, whichever is less, provided that such street walls are set back a minimum distance of 10 feet from the Surf Avenue street line. All portions of buildings or other structures that exceed a transition height of 95 feet shall comply with the tower provisions of Section 131-444 (Coney North Subdistrict towers).
