(2)        The maximum base height of a street wall may vary between the height of the street wall of an adjacent building before setback, if such height is higher than the maximum base height allowed, and the maximum base height requirements of Section 35-652, provided that such height not exceed 150 feet and provided that such zoning lot is located within the area bounded by West 22nd Street, a line 100 feet west of Fifth Avenue, a line midway between West 16th Street and West 17th Street, and a line 100 feet east of Sixth Avenue.

(3)        The location of the street wall of any building may vary between the street wall location requirements of Section 35-651, or as modified in any applicable Special District, and the location of the street wall of an adjacent building fronting on the same street line.

Such open area may be obstructed only by the permitted obstructions set forth in Section 33-23 (Permitted Obstructions in Required Yards or Rear Yard Equivalents).

(h)        For the purposes of applying the street wall location regulations of paragraph (b) of this Section, any building wall oriented so that lines perpendicular to it would intersect a street line at an angle of 65 degrees or less shall not be considered a street wall.

(i)        For the purposes of applying the street wall location as well as the height and setback provisions of Sections 35-651 and 35-652, respectively, where the Administrative Code establishes restrictions on the location of buildings on lots fronting upon and within 30 feet of Eastern Parkway in Community Districts 8 and 9 in the Borough of Brooklyn, lines drawn 30 feet north of and 30 feet south of, and parallel to, Eastern Parkway shall be considered the northern and southern street lines of Eastern Parkway.
