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.)
