Any portion of a building that exceeds a height of 125 feet shall comply with the following provisions:

(a)        Tower location and maximum tower height

All towers shall be located entirely within a Tower Area as designated on Map 6 (Tower Areas), in Appendix A of this Chapter. The maximum height of such towers shall be as indicated for the specified location on Map 6. For buildings higher than 165 feet, the stories entirely within 40 feet of the highest roof level of the building shall have a lot coverage of at least 50 percent of the story immediately below such stories, and a maximum lot coverage of 80 percent of the story immediately below such stories. Such reduced lot coverage shall be achieved by one or more setbacks on each face of the tower, where at least one setback on each tower face has a depth of at least four feet, and a width that, individually or in the aggregate, is equal to at least 10 percent of the width of such respective tower face. For the purposes of this paragraph, each tower shall have four tower faces, with each face being the side of a rectangle within which the outermost walls of the highest story not subject to the reduced lot coverage provisions have been inscribed. The required setbacks shall be measured from the outermost walls of the building facing each tower face. Required setback areas may overlap.

(b)        Orientation and maximum tower size

The outermost walls of each story located entirely above a height of 125 feet shall be inscribed within a rectangle. The maximum length of any side of such rectangle that is parallel or within 45 degrees of being parallel to Second Street or Center Boulevard, whichever is closest, shall be 95 feet. The maximum length of any other side of such rectangle shall be 170 feet. Each story of a tower located entirely above a height of 125 feet shall not exceed a gross area of 11,000 square feet.

However, on Parcel G in the East River Subdistrict, the maximum length of the side of such rectangle that is parallel or within 45 degrees of being parallel to Second Street shall not exceed 170 feet.

(c)        Tower and base integration

Notwithstanding the setback provisions of paragraph (c) of Section 125-33, up to 50 percent of the street wall width of a tower may rise sheer from grade without setback.
