In M2-4 Districts in Western Subarea C2, the underlying height and setback regulations shall apply as modified by the following special bulk regulations.

For all buildings or other structures, the street wall of a building shall rise without setback to a minimum base height of 50 feet, or the height of the building, whichever is less, and a maximum base height of 95 feet. No portion of a building shall exceed a height of 135 feet and no sky exposure plane shall apply.

On wide streets, and on narrow streets within 50 feet of their intersection with a wide street, the street wall shall be located on the street line and extend along such entire street frontage of the zoning lot up to at least the minimum base height.

On narrow streets beyond 50 feet of their intersection with a wide street, the street wall shall be located on the street line and extend along at least 70 percent of the narrow street frontage of the zoning lot up to at least the minimum base height.

Where street walls are required to be located on the street line, recesses, not to exceed three feet in depth from the street line, shall be permitted on the ground floor where required to provide access to the building. Above a height of 12 feet, up to 30 percent of the aggregate width of street walls may be recessed beyond the street line, provided any such recesses deeper than 10 feet along a wide street, or 15 feet along a narrow street, are located within an outer court. Furthermore, no recesses shall be permitted within 30 feet of the intersection of two street lines except that, to allow articulation of street walls at the intersection of two street lines, the street wall may be located anywhere within an area bounded by the two street lines and a line connecting such street lines at points 15 feet from their intersection.
