All towers and antennae located within the city must conform to the applicable performance standards contained in this section.
(1) Collocation requirements. In all areas of the city, antennas and towers shall be located on existing structures, buildings or towers within a one-mile radius of the proposed location unless the proposed antenna or tower cannot be accommodated on an existing structure, building or tower due to one or more of the following reasons:
a. The planned equipment would exceed the structural capacity of the existing or approved structure, building or tower, as documented by a qualified and licensed professional engineer, and the existing or approved structure, building or tower cannot be reinforced, modified, or replaced to accommodate planned or equivalent equipment at a reasonable cost.
b. The planned equipment would cause interference materially impacting the usability of other existing or planned equipment at the structure, building or tower as documented by a qualified and licensed professional engineer and the interference cannot be prevented at a reasonable cost.
c. An existing or approved structure, building or tower within the one-mile radius cannot accommodate the planned equipment at a height necessary to function reasonably as documented by a qualified and licensed professional engineer.
d. Other unforeseen reasons make it infeasible to locate the planned telecommunications equipment upon an existing or approved structure, building or tower.
e. If the proposed antenna or tower cannot be accommodated on an existing structure, building or tower for the reasons set forth in this section, antennas and towers may be located on available public or institutional land. Antennas placed on public or institutional land (government, school, utility, public park land, and church sites) in residential districts shall be incorporated into the principal structure, when available, rather than placed on a tower separate from the principal building. On public property, antennas shall be mounted on structures, when available, that serve other purposes such as light standards or emergency siren poles. If structures are not available or are unable to accommodate proposed antennas or towers, a tower separate from the principal structure may be constructed.
If public or institutional land is not available, antennas and towers may be located on private property, with a conditional use permit, limited to the following priority areas:
1. Priority one is limited to only B-l, B-2, B-3, B-4, 1-1, 1-2, and BP zoning districts and/or land guided for commercial or industrial land use on the adopted Future Land Use Plan.
2. Priority two is limited to only RM and RH zoning districts and/or land guided for medium or high density residential land use on the adopted Future Land Use Plan.
f. Any proposed tower shall be designed, structurally, electrically, and in all respects, to accommodate both the applicant’s antennas and comparable antennas for at least 2 additional users if the tower is over 100 feet or for at least 1 additional user if the tower is over 75 feet in height. Towers must be designed to allow for future rearrangement of antennas upon the tower to accept antennas mounted at varying heights.
(2) Antenna collocation requirements. The placement of personal wireless service antennas on roofs, walls, and existing towers may be approved by the City, with a building permit. In addition to the submittal requirements required elsewhere in this Code, an application for a building permit for antennas to be mounted on an existing structure shall be accompanied by the following information:
a. A site plan showing the location of the proposed antennas on the structure and documenting that the request meets the requirements of this Code;
b. A building plan showing the construction of the antennas and the proposed method of attaching them to the existing structure, and documenting that the request meets the requirements of this Code;
c. Certification by a qualified and licensed professional engineer indicating the existing structure’s or tower’s ability to support the antennas.
(3) Tower and antenna design requirements. Proposed or modified towers and antennas shall meet the following design requirements:
a. Towers and antennae shall be designed to blend into the surrounding environment through the use of color and design and camouflaging architectural treatment;
b. Towers shall be of a monopole design unless the City Council determines that an alternative design would better blend into the surrounding environment;
c. The use of guyed towers is prohibited. Towers must be self-supporting without the use of wires, cables, beams or other designs; and
d. The base of the tower shall occupy no more than 500 square feet and the top of the tower shall be no larger than the base.
e. Antenna attachments to towers shall be as inconspicuous as possible.
f. Ground equipment shall be screened from all property lines. Screening shall be accomplished through landscaping and shall be of an evergreen type and tall enough to limit the view of the equipment. Any fencing shall be similarly screening. Any equipment or storage buildings shall meet the standards of the underlying zoning district for building materials and meet the following design requirements:
1. Include at least 2 major exterior materials in 2 complementary colors.
2. Roof design shall be pitched.
3. All service doors shall be painted to match primary materials or serve as an accent element.
4. Colored building elevations shall be submitted at time of conditional use permit application.
5. The City Council may consider alternative designs through the conditional use permit process.
a. The height of towers shall be determined by measuring the vertical distance from the tower’s point of contact with the ground or rooftop to the highest point of the tower, including all antennas or other attachments. When towers are mounted upon other structures, the combined height of the structure at the tower’s point of attachment and tower must meet the height restrictions of this section.
b. Towers are exempt from the maximum height restrictions of the districts where located.
c. In residential zoned property where a tower or antennae is located on public or institutional land, the maximum height of any tower, including all antennas and other attachments, shall not exceed 1 foot for each 2 feet the tower is set back from abutting residential property up to a maximum height of 120 feet.
d. In mixed-use zoned or guided property, antennas and towers are not permitted.
e. In all Non-Residential Zoning Districts, the maximum height of any tower, including all antennas and other attachments, shall not exceed 1 foot for each 2 feet the tower is set back from protected residential property, up to a maximum height of 150 feet. The City Council may allow towers up to 200 feet high if the applicant can demonstrate, based upon the topography of the site and surrounding area, siting of the antenna, antenna design, surrounding tree cover and structures and/or through the use of screening, that off-site views of the tower will be minimized. Owners of certain antenna structures more than 200 feet above ground level at the site must notify the Federal Aviation Administration and register with the Federal Communications Commission.
f. The City encourages the use of City property in accordance with the procedures of the City Charter and Code. The City shall have no obligation whatsoever to use City property for these purposes.
g. No telecommunications facilities may be located within a distance equal to twice the height of the proposed tower of any use that involves the storage, distribution, or sale of volatile, flammable, explosive, or hazardous materials such as LP gas, propane, gasoline, natural gas, and corrosive or dangerous chemicals (hereinafter referred to a flammable storage use) unless the applicant can demonstrate, to the satisfaction of the City, that no danger exists in locating the telecommunications facilities in the proposed proximity to the flammable storage use.
h. Height exceptions. The following are exceptions to the maximum height restrictions for towers:
1. Multiuser towers. Multiuser towers may exceed the height limitations of this section by up to 20 feet, provided that if only the antennas of a single personal wireless service provider will be attached to the tower at the time of application, the additional 20 feet will not be used but will remain vacant for use by a second personal wireless service provider.
2. Amateur radio antenna. In accordance with the preemption ruling PRB1 of the Federal Communications Commission, towers supporting amateur radio antennas that comply with all other requirements of this section are exempted from the height limitations of this section up to a total height of 70 feet, provided that such height is technically necessary to receive and broadcast amateur radio signals.
3. Attached to structures. Towers and other antenna devices which are attached to a structure and not freestanding may be located in residential zoned districts under the following conditions:
(a) The towers and antennas are located upon existing or proposed structures allowed as principal or conditional uses in the underlying zoning district and/or upon public structures; and
(b) The towers and antennas are limited to a height of 15 feet projecting above the structure. The City Council may permit antenna heights of up to 25 feet above the structure if the applicant can demonstrate that, by a combination of antenna design, positioning of the structure and/or by screening erected or already in place on the structure, off site views of the antenna are minimized to accepted levels.
4. Public utility structures. Public utility structures, including, but not limited to, water towers, antennas, lights and signals, power and telephone poles, and poles supporting emergency warning devices.
5. Wireless antennas attached to public utility structures. Wireless antennas located on or attached to public utility structures within public right-of-way or in drainage and utility easements adjacent to public right-of-way allowed pursuant to a lease or master agreement with the City providing for review of the location, height and safety of the structure and antenna.
