ZR § 91-33

Above the maximum base height specified in Section 91-31 (Street Wall Regulations), up to a height of 300 feet, the maximum lot coverage of any zoning lot shall be 65 percent. Above a height of 300 feet, the maximum lot coverage of any zoning lot shall be 50 percent.

However, within the Historic and Commercial Core, above the maximum base height specified in Section 91-31, up to a height of 300 feet, the maximum lot coverage of any zoning lot shall be 75 percent. Above a height of 300 feet, the maximum lot coverage of any zoning lot shall be 60 percent.

For buildings fronting on more than one street where different maximum base heights are specified, the maximum lot coverage regulations specified in this Section shall apply at horizontal planes at heights corresponding to the different maximum base heights. The lot coverage at the level of the lowest plane shall apply to the portion of a zoning lot located beyond 100 feet from any street with a higher maximum base height. The lot coverage at the level of each subsequent higher plane shall apply to the portion of the zoning lot located beyond 100 feet from any street with a higher maximum base height, and shall also include those portions of the zoning lot where lower base heights apply. The highest horizontal plane shall be established over the entire zoning lot.
