(A) Maximum. Except as hereinafter provided, no building or structure, or part thereof, shall hereafter be erected or altered to a height greater than the maximum specified for the respective category.
(B) How measured.
(1) For the purpose of this chapter, the HEIGHT of a wall or structure or a part of a building is the mean vertical distance from the average established grade in front of the lot, or from the average natural grade at the building line, if higher, to the average height of the top of the cornice of flat roofs, or roof line, or to the deck line of a mansard roof, or to the middle height of the highest gable or dormer in a pitched or hipped roof, or if there are no gables or dormers, to the middle height of such pitched or hipped roof.
(2) Where a lot abuts on two or more streets or alleys of different average established grades in front of the lot, the higher of such grades shall control only for a depth of 120 feet measured perpendicularly back from the line of the higher street or alley.
(3) On a corner lot the height of the mean vertical distance from the average natural grade at the building line, if higher, in the street of greatest width, or if two or more such streets are of the same width, form the highest of such grades. The height limitations as controlled by the wider street shall govern for a distance of 120 feet measured at right angles back from such wider street, except on parts of such 120 feet as may be within a more restricted height.
(C) Exceptions of height limits.
(1) Notwithstanding other regulations in this chapter or the maximum specified for the respective category, the height limits of this chapter shall not apply for the following: barns, silos or other farm structures on farms; church spires, belfries, cupolas and domes; monuments; water towers; observation towers; transmission towers; windmills; chimneys; smokestacks; derricks; conveyors; flag poles; radio towers; masts and aerials; bulkheads; elevator penthouses; fire towers; hose towers; cooling towers; grain elevators; and other structures, where the manufacturing process requires a greater height; provided, however, that all such structures above the limiting heights specified in this zoning chapter shall not be closer than 25 feet from every lot line not a street lot line, and shall be set back one foot from the otherwise required setback at the limiting height, for each foot of vertical height above the limiting height; and
(2) Solar heating and solar collection devices, provided such devices do not exceed by more than five feet the otherwise permitted maximum height for the zone in which they are located.
