The height of a building shall be the vertical distance measured from the average level of the ground surrounding the entire perimeter of the building to the highest point of the roof for flat roofs and the highest ridge for gable, hip and gambrel roofs, provided that chimneys, spires, towers, mechanical penthouses, elevator penthouses, tanks and antennas and similar projections from the building roof not intended for human occupancy, shall not be included in calculating the building height, provided such projections shall not be more than eight feet higher than the highest point of the roof for flat roofs or the highest ridge for gable, hip and gambrel roofs. Where chimneys, spires, towers, mechanical penthouses, elevator penthouses, tanks, antennas and similar projections from the building roof are more than eight feet higher than the highest point of the roof for flat roofs or the highest ridge for gable, hip and gambrel roofs, the top of the roof shall be the highest point of any such projection. The level of ground at any given point along the perimeter of the structure shall be the lowest point of any area within six feet away from the structure at that point. The average level of the ground shall be calculated by measuring the level of ground every one foot along the entire perimeter of the structure, adding all such measurements and dividing by the total length of the perimeter in feet. (For example, 50 linear feet at elevation two feet (100) plus 150 linear feet at elevation six feet (900), for total measurements of 1,000, divided by total linear feet of 200, equals an average level of the ground of five.)
