The executive director shall make the final determination on the height necessary for their proper functioning. Attics shall not exceed fourteen feet in height.(c) Where the floor plate ratio identified in Figures BT.1 to BT.10, dated September 2011, made a part of this chapter, and attached at the end of this chapter, indicate a value of less than one hundred per cent, the remainder value of setback area is considered the building void (see Figure 1.12-C (illustrative building void and floor plate diagrams), dated September 2011, made a part of this chapter, and attached at the end of this chapter). At least twenty-five per cent of the building void shall be located along the facade and have a minimum depth of ten feet, as measured from the facade toward the rear lot line; provided, however, that this minimum depth from the facade shall be increased by three feet for every ten feet of building height.(d) Any part of a building which is taller than sixty-five feet and fronting a view corridor street (see Figure 1.6A (view corridors), dated September 2011, made a part of this chapter, and attached at the end of this chapter) shall be setback from the lot line abutting the view corridor by fifty feet.(e) Except in the Sheridan neighborhood zone, all ground floors shall be at least twelve feet tall along all thoroughfares.(f) All new principal buildings shall be designed with a street front element conforming to Figure 1.3-D (development standards summary - building form), dated September 2011, made a part of this chapter, and attached at the end of this chapter.
