Chimneys extending not more than three feet above the highest point of the roofed structure shall not be included in the building height. For dwellings with pitched roofs located in the A-3 District on lots specifically authorized for pitched roof measurement by the Planning Board as part of a filed subdivision plat, the height of a building is the vertical distance measured from the mean original ground level surrounding the building at the street wall to a point midway between the highest and lowest points of the roof (Diagram B), provided that chimneys shall not be included in the building height if they do not extend more than three feet above the highest portion of the roof.
