The purpose of this chapter is to establish predicable, balanced regulations for the siting and screening of wireless communications equipment in order to accommodate the growth of wireless communicating systems within the City while protecting the public against any adverse impacts on the City's aesthetic resources and the public welfare. (Prior Code § 20-33-1)

The following standards shall apply to all personal wireless service, public utility, microwave, radio and television broadcast transmitting, radio and television receiving, satellite dish and short wave radio transmitting and receiving antennas.

   A.   All obsolete and unused antennas shall be removed within twelve (12) months of cessation of operation at the site, unless an exemption is granted by the Zoning Administrator.

   B.   All antennas shall be in compliance with all City Building and Electrical Code requirements and, as applicable, shall require related permits.

   C.   Structural design, mounting and installation of the antenna shall be in compliance with manufacturer's specifications and shall be verified and approved by a registered professional engineer.

   D.   Unless the antenna/antenna support structure and land is under the same ownership, written authorization for antenna erection shall be provided by the property owner.

   E.   No advertising message shall be affixed to the antenna structure.

   F.   The height of the antenna shall be the minimum necessary to function satisfactorily, as verified by an electrical engineer or other appropriate professional.

   G.   Antennas shall not be artificially illuminated unless required by law or by a governmental agency to protect the public's health and safety.

   H.   When applicable, proposals to erect new antennas shall be accompanied by any required Federal, State, or local agency licenses.

   I.   If a new antenna support structure is to be constructed, it shall be designed so as to accommodate other users including, but not limited to, other personal wireless service communication companies and local police, fire and ambulance companies.

   J.   Antenna support structures under two hundred feet (200') in height shall be painted silver or have a galvanized finish to reduce visual impact, unless otherwise required by Federal law.

   K.   Except as may be applicable in cases where a conditional use permit is required, antennas and support structures for Federally licensed amateur radio stations and used in the amateur radio service are exempt from subsections C, F, and I of this section, and must comply with subsection L of this section.

   L.   Amateur radio support structures (towers) must be installed in accordance with the instructions furnished by the manufacturer of that tower model. Because of the experimental nature of the amateur radio service, antennas mounted on such a tower may be modified or changed at any time so long as the published allowable load on the tower is not exceeded and the structure of the tower remains in accordance with the manufacturer's specifications. (Prior Code § 20-33-2)

The following standards shall apply to all accessory and secondary use antennas including radio and television receiving antennas, satellite dishes, TVROs three and one-half meters (3.5 m) or less in diameter, short wave radio dispatching antennas, or those necessary for the operation of electronic equipment including radio receivers, Federally licensed amateur radio stations and television receivers.

   A.   Accessory or secondary use antennas shall not be erected in any required yard (except a rear yard) or within public or private utility and drainage easements, and shall be set back a minimum of five feet (5') from all lot lines.

   B.   Guy wires or guy wire anchors shall not be erected within public or private utility and drainage easements, and shall be set back a minimum of five feet (5') from all lot lines.

   C.   Accessory or secondary use antennas and necessary support structures, monopoles or towers may extend a maximum of fifteen feet (15') above the normal height restriction for the affected zoning district, except support structures and antennas used in the amateur radio service may extend a maximum of seventy feet (70') for the affected zoning district.

   D.   The installation of more than one support structure per property shall require the approval of a conditional use permit. (Prior Code § 20-33-3)

   A.   Agricultural And Residential District Standards:

      1.   Antennas Located Upon Public Structures: Personal wireless service antennas located upon public structures shall require the processing of an administrative permit and shall comply with the following standards:

         a.   The applicant shall demonstrate by providing a coverage/interference analysis and capacity analysis prepared by a registered professional engineer that location of the antennas as proposed is necessary to meet the frequency reuse and spacing needs of the personal wireless service system and to provide adequate portable personal wireless service coverage and capacity to areas which cannot be adequately served by locating the antennas in a less restrictive district.

         b.   Transmitting, receiving and switching equipment shall be housed within an existing structure whenever possible. If a new equipment building is necessary for transmitting, receiving and switching equipment, it shall be situated in the rear yard of the principal use and shall be screened from view by landscaping where appropriate.

            (1)   The pole not exceed seventy five feet (75') in height.

            (2)   The setback of the pole from the nearest residential structure is not less than the height of the antenna. Exceptions to such setback may be granted if a qualified structural engineer specifies in writing that any collapse of the pole will occur within a lesser distance under all foreseeable circumstances.

         d.   Transmitting, receiving and switching equipment shall be housed within an existing structure whenever possible. If a new equipment building is necessary for transmitting, receiving and switching equipment, it shall be situated in the rear yard of the principal use and shall be screened from view by landscaping where appropriate.
