10-17A-6: COMMUNICATION TRANSMISSION FACILITIES, INCLUDING WIRELESS, PRIMARY – SPECIFIC STANDARDS:
A. A six-foot-four-inch (6'4") in height solid masonry fence is required to fully enclose the facility. The fence and the facility shall not be located in the front yard setback, within any required landscape or buffer area, or within required parking area. All power lines on the lot leading to an antenna structure and accessory structures shall be underground. Guyed facilities are not permitted.
B. The front yard setback shall be landscaped in accordance to the commercial standards set forth in sections 10-23-1 through 10-23-3.
C. Lots created and intended for the sole purpose to provide a public utility may be subdivided with less than the required amount of square footage per the zone.
D. Accessory structures must comply with the required setback and height requirements of the zoning district in which they are located, and be located inside the fenced area.
E. The height of any antenna structure or communication transmission pole shall not exceed fifty feet (50'), unless the zone permits antenna structures greater than fifty feet (50'), and a conditional use permit is issued in compliance with chapter 17B of this title. No antenna structure shall exceed one hundred feet (100') in height in any zone.
F. Monopole with Antennas and Antenna Support Structures: The maximum visible width of antennas and antenna mounting structures on a monopole shall not exceed eight feet (8') in height or thirteen feet (13') in width as viewed looking directly at the monopole at the same elevation as the antennas and antenna mounting structure. No such antenna shall be located within one hundred fifty feet (150') of a residential zone. The climbing pegs shall be removed from the lower twenty feet (20') of the monopole.
G. Lattice Tower: A lattice tower is not allowed within any residential, administrative professional, or commercial zone, including all similar planned development zones.
H. Antennas and Mounting Structures on or over Public Right-of-Way: Antennas and mounting structures are not permitted to encroach on or over the public sidewalk, or on or over a public right-of-way.
I. Nonmaintained, Nonoperational or Abandoned Facilities: The communication company and the landowner shall remove any nonmaintained, nonoperational or abandoned communication pole, communication tower, antenna, and incidental infrastructure within thirty (30) calendar days of cessation of use.
J. Permits: Prior to construction or installation, applicant shall obtain the proper building permits, encroachment permits and such other permits as required by law.
K. The foregoing notwithstanding, outside of the St. George arts district overlay zone, the following facilities are a permitted use:
1. Collocation of antennas on existing nontower structures in industrial, commercial, agricultural, open space, or gravel and grazing zones; provided, the additional antennas are no more than ten feet (10') higher than the existing structure, and the color of the antennas blend with the surroundings, and not more than three (3) providers are locating on the structure. The total height of the structure shall not exceed the permitted height in the zone.
2. Wall-mounted antennas which do not extend above the wall line of the building or extend more than four feet (4') horizontally from the wall.
3. Wireless communication facilities located on city property, subject to complying with standards contained herein, and obtaining a lease agreement with the city.
4. Any provider who is authorized to collocate on an existing tower or nontower structure, or install a new tower as provided above, shall be allowed to install any necessary accessory equipment shelters and related equipment at or near the base of the tower or structure, or within the structure, so long as the accessory equipment shelter and related equipment are either located completely within the existing structure or are located within the approved fence area. The equipment shelter shall comply with the development standards (i.e., setbacks, height limitations, bulk, etc.) of the zone. No previously approved landscaping (trees or shrubs) shall be removed in order to locate the accessory building or equipment unless it is replaced with the equivalent quantity and type of landscaping on site. This shall be done in a manner as to achieve the original intent, or to achieve sufficient screening of any proposed new shelter and/or equipment if the original intent would no longer be applicable.
L. Additional standards for the following types of antennas:
1. Wall-Mounted Antennas: The following criteria apply to wall-mounted antennas:
a. Wall-mounted antennas shall not extend above the wall line of the building or extend more than four feet (4') horizontally from the face of the building.
b. Antennas, equipment and the supporting structures shall be painted to match the color of the building or structure of the background against which they are most commonly seen. Antennas and the supporting structures on buildings must be architecturally compatible with the building. Whip antennas are not allowed on a wall-mounted antenna structure.
c. An antenna mounted directly on an existing parapet wall, penthouse or mechanical equipment room, with no portion of the antenna extending above the roofline of such structure, is a wall-mounted antenna.
2. Roof-Mounted Antennas:
a. Allowed on top of existing penthouses or mechanical equipment rooms; provided, the antennas and antenna support structures are enclosed by a structure that screens the antenna from public view. The screening structure, antennas and antenna-mounting structures shall not extend more than eight feet (8') above the existing roofline of the penthouse or mechanical equipment room.
b. For antennas not mounted on a penthouse or mechanical equipment room, the antennas shall be mounted at least five feet (5') from the exterior wall of a building.
c. For antennas mounted between five (5) and ten feet (10') from the exterior wall, the maximum height of a roof-mounted antenna is directly proportional to the distance the antenna is set back from the exterior wall up to a maximum height of ten feet (10') above the roofline of the building to which the antenna is attached. Antennas shall be mounted at least five feet (5') behind any parapet wall.
d. For antennas mounted behind a parapet wall, the maximum height of the antenna is directly proportional to the distance the antenna is set back from the wall up to a maximum height of ten feet (10') as measured from the top of the parapet wall.
e. Roof-mounted antennas on a pitched roof shall be allowed; provided, the antennas and antenna-support structures do not extend higher than the peak of the roof measured by a horizontal line from the peak extending over the roof.
f. Area Limitation for Wall- and Roof-Mounted Antennas: A combination of both roof- and wall-mounted antennas are allowed on a building. The total area for all wall- and roof-mounted antennas and supporting structures combined shall not exceed forty (40) square feet for each exterior wall of the building or a total of one hundred sixty (160) square feet per building. Up to three (3) carriers may utilize each building side as a permitted use subject to compliance with this chapter.
M. Wireless telecommunication facilities must meet the following additional standards: A site-location development master plan shall be submitted by each company providing wireless services or a landowner in joint application with a wireless company desiring placement of wireless telecommunication facilities. The development master plan shall show the general location of all proposed sites and show the coverage area provided by the location. The master plan is intended to show approximate service areas.
