No principal structure in any district may be constructed, reconstructed, altered, or enlarged which exceeds 35 feet in height above average ground level. One-story primary structures may not have accessory structures that exceed 16 feet in height. Two-story or taller primary structures may not have accessory structures that exceed 24 feet in height.
(A) The following structures may exceed normal height requirements; provided their total height does not exceed their distance from the nearest lot line:
(1) Structures such as barns, silos, tanks, bins, and windmills located in the Agricultural District;
(2) Communication structures, such as wireless towers (as defined), radio and television and relay stations and receiving stations, and aerials and observation towers; and
(3) Industrial uses such as gas and liquid fertilizer tanks, sanitary landfills, power generating plants, sub-stations, smoke-stacks, grain elevators, and other agricultural product processing and storage facilities, and industries requiring a vertical production procedure, such as flour mills, steel mills, and refineries;
(4) Architectural projections, such as spires, belfries, parapet walls, cupolas, and domes;
(5) Special structures such as monuments, scenery lofts, fire towers, and flagpoles; and
(6) Wind energy conversion systems (as defined).
(B) Public and semi-private buildings, hospitals and institutions, schools, and churches (excluding the spire) may be erected to a height of 60 feet; provided their total height does not exceed their distance from the nearest lot line.
(C) Auxiliary structures attached to a building such as radio and television antennae, chimneys, ventilation fans, and similar mechanical appurtenances, or other structures necessary to maintain and operate a building may exceed normal height requirements; provided the building is setback from the minimum yard distances one additional foot for each foot of height above the maximum height limitations. If the auxiliary structure is erected at a later time than the building to which it is attached, the auxiliary structure, rather than the building, must be so located that the provisions of this division (C) can be met.
(D) Essential services, utilities, water towers, electric power and communication transmission lines, and vegetation are exempt from the height limitations of this chapter.
(E) The above height exception shall not apply when the structure constitutes a hazard to an existing airport or landing strip and to electric power transmission lines.
(F) The Board of Zoning Appeals may authorize a variance to this regulation for any principal or accessory structure in any district; provided division (E) above is met.
