(A) Antennas and dish-type antennas having a diameter no greater than 30 inches. Antennas and towers having over-all heights of 75 feet or less are a permitted use in all districts and are permitted encroachments on height requirements of this code. This includes towers of all types and antennas of all types and sizes except dish-shaped antennas having a diameter greater than 30 inches. Antennas and dish- shaped antennas having a diameter of 30 inches or less are exempt from any requirement for a building permit, but are subject to excavation permit requirements when applicable. Antennas and towers higher than 75 feet require a conditional use permit.
(1) Vertical antennas. The bottom of the base of a mast- or tower-mounted vertical antennas may be at a height of 75 feet or less with no over-all height limit for the top of the antenna. The highest point of any ground mounted vertical antenna, however, may be no more than 75 feet.
(2) Directional satellite communications antennas. The point at which the main boom of a directional, non-dish-type satellite communications antenna or antenna array is attached to its support structure (tower, mast, rotator, and the like) can be no more than 75 feet high. The uppermost part(s) of such antenna(s) can be at 100 feet.
(3) Height. The height of an antenna, dish antenna, or tower shall be measured from the adjacent ground elevation at the base of the antenna, dish, or tower to the highest point of the antenna or tower. If the antenna or tower is mounted on a building, height is measured from the average grade level on which the building is constructed.
(4) Definitions. For the purpose of this section, the following definitions shall apply unless the context clearly indicates or requires a different meaning.
ANTENNA. A wire or other device that receives or transmits radio waves.
DIRECTIONAL SATELLITE COMMUNICATIONS ANTENNA. Any directional antenna or antenna array designed to provide radio communications using satellites, manned or unmanned spacecraft, moonbounce, troposcatter, meteor-trail ionization, or similar vehicles or propagation modes.
TOWER. A structure to which an antenna is attached.
(B) Installation requirements. An excavation or building permit is required for all towers and antennas for which excavation is required. All antennas and towers must conform to the Uniform Building Code, the National Electric Code, the city/county airport zoning ordinance, and the regulations of the Federal Airways Administration (FAA) and Federal Communications Commission (FCC). Antennas or towers may be installed in utility casements if a waiver is obtained from the City Engineer and the City Council.
(C) Tower locations. Antennas and towers shall not be allowed nearer the street than the principal building on the lot; and nearer the rear or side lot lines than the minimum rear or side yard setback. Wire antennas are exempt from this requirement.
(D) Encroachment. No part of an antenna may extend beyond the lot line over an adjoining lot without written permission from the owner or lessee of that adjoining lot.
(E) Reservations. The city reserves the right to permit antennas, in its sole discretion, on the top of water towers, high rise buildings, and other structures.
