§ 60.219. Amateur radio antennae and antenna support structures.
The installation, construction and maintenance of amateur radio antennae and antennae support structures shall be governed by the provisions of this section.
(Ord. No. 07-2009, 3-3-2009)
Section 60.219.1. Definitions.
Antenna. The arrangement of wires or metal rods used in the sending and receiving of electromagnetic waves between terrestrially and/or orbitally based structures.
Antenna support structure. Any structure, mast, pole, tripod or tower utilized for the purpose of supporting an antenna or antennae for the purpose of transmission or reception of electromagnetic waves by a federally licensed amateur radio operator.
Antenna support structure height. The overall vertical length of the antenna support structure above grade, or if such system is located on a building or other structure, then the overall vertical length shall include the height of the building or structure upon which the antenna support structure is mounted.
(Ord. No. 07-2009, 3-3-2009)
Section 60.219.2. Requirements.
The following requirements shall apply to any amateur radio antenna support structure:
(a)
No such antenna support structure shall be installed without the appropriate building permit being obtained under applicable building code provisions. A building permit shall be obtained for each such installation unless the antenna support structure is less than 12 feet in height and is otherwise be exempt from the application of the building code.
(b)
Where an application for building permit is required as set forth in subsection (a) above, in addition to any other building code application requirements, the following information shall be submitted with the application for the building permit:
(1)
A location plan for the antenna support structure including details of any guy wires, footings, and/or braces designed according to sound engineering practices.
(2)
Manufacturer's specifications for the antenna support structure and requirements for footings, guy wires and braces.
(3)
Proof or certification that the applicant has liability insurance coverage applicable to the antenna support structure insuring against general public liability for personal injury, bodily injury and property damage.
(c)
Height Limitation. No antenna support structure shall be installed, constructed, or increased to exceed:
(1)
Sixty-five feet above grade in any single-family residential zoning district.
(2)
The greater of 100 feet or the distance such structure is to the nearest lot line of the zoning lot or tract on which the structure is located (height to be measured above grade) in an agriculturally zoned district.
(3)
Thirty feet above the height limitation otherwise allowed for structures in any other zoning district.
No antenna, with mast, shall be installed on any antenna support structure such that more than 35 feet is added to the overall height of the installation (support structure height plus antenna height with mast) and such installation shall not exceed an overall height from grade of 100 feet. To accommodate safe stacking of all antenna arrays, the mast holding the antenna(s) shall be designed to support and maintain the integrity of the antennas and the supporting tower structure. The mast shall be constructed of material that provides the appropriate PSI yield strength (the point where the mast will deflect and not return to its original shape) to insure stacking integrity.
(d)
All antenna support structures shall meet the following requirements:
(1)
All steel antenna support structures shall be designed, erected and maintained in accordance with the requirements of the Electronic Industries Association Structural Standards for Steel Antenna Towers and Antenna Supporting Structures and shall meet a wind loading requirement of at least 70 miles per hour. In all installations, materials and manner of installation shall meet or exceed the manufacturer's minimum requirements, and all ground-mounted antenna support structures shall be installed in a concrete base.
(2)
All aluminum antenna support structures shall be designed, erected and maintained in accordance with standard and sound engineering practices and shall meet a wind loading requirement of at least 70 miles per hour. In all installations, materials and manner of installation shall meet or exceed the manufacturer's minimum requirements, and all ground-mounted antenna support structures shall be installed in a concrete base.
(3)
Electrical requirements. All antenna support structures, whether ground or roof-mounted, shall be grounded with a minimum of one ground rod a minimum of five-eighths inch in diameter and eight feet in length. The ground conductor shall be a minimum of number 10 GA copper. In all installations, electrical requirements shall meet or exceed the manufacturer's minimum requirements for grounding and installation.
(e)
Restrictions. The following restrictions shall apply to amateur radio antennae and support structures:
(1)
No antenna shall protrude in any manner over or upon the property adjoining the location where the antenna is located without the written consent and permission of the adjoining property owner and the zoning administrator, subject to review by the planning and zoning commission.
(2)
No antenna shall protrude upon or across any public property or right-of-way or be located upon any public property or right-of-way.
(3)
No ground-mounted antenna support structure shall be erected in a front yard, and all such structures shall meet rear and side yard requirements.
(4)
Transmission repeater towers which exceed the height or other limitations of these regulations shall be subject to the provisions of section 60.218 et seq.
(5)
No more than one antenna support structure shall be erected on any zoning lot from and after the effective date of this Ordinance unless a special use for such multiple installation is granted under subsection 60.219.2(f), below.
(f)
Any amateur radio operator desiring to install, erect or maintain an antenna support structure and/or antenna at a height in excess of that otherwise permitted under this section or in a manner different from that permitted by this section shall apply for a variance under the procedures of section 60.907 et seq. In addition to the standards of section 60.907.2, the reviewing bodies shall also consider the topographical conditions present and/or other operational parameters of the antenna or radio equipment proposed for use by the operator which may justify the variance. In each instance where a variance is granted, adequate provision shall be made by conditions on the variance to protect adjoining properties.
(Ord. No. 07-2009, 3-3-2009)
Section 60.219.3. Exemptions.
The provisions of this section 60.219 shall not be applicable to any existing antenna and antenna support structure utilized by a federally licensed amateur operator which has been legally constructed and is in place prior to the effective date of this Ordinance, provided, however, that the height of such installation (support structure height plus antenna(e) height with mast) shall not be increased beyond its overall height at such effective date without compliance with the provisions of this section 60.219. The antenna height limit of section 60.219.2 (ten feet) shall apply to such installations. All such existing support structures must be maintained continuously in a safe condition and state of good repair.
