WIRELESS TELECOMMUNICATIONS FACILITIES ORDINANCE
20-8.5 Purpose. The purpose of this section is to address planning issues brought
on by the rapid growth in demand for low power radio services. This
Section distinguishes low power radio from other broadcasting type
telecommunication technologies and establishes provisions that deal with
issues of demand, visual mitigation, noise, engineering, residential impacts,
health, safety and facility siting.
(a) Low Power Radio Services Facility. The requirements of this
Section apply to both commercial and private low power radio
services such as "cellular" or "PCS" (Personal Communications
System) communications and paging systems. All facilities shall
comply with the following regulations and all other ordinances of
the City and any pertinent regulations of the Federal
Communications Commission and the Federal Aviation
Administration.
(1) Permitted Uses. The uses specified in Table 1 are allowed
provided that they comply with all requirements of this
Section.
(2) Facility Types. Low power radio services facilities are
characterized by the type or location of the antenna structure.
There are five general types of such antenna structures: Wall
mounted antennas; roof mounted antennas; monopoles with
antennas and antenna support structure less than two (2) feet
in width; monopoles with antennas and antenna support
structure greater than two (2) feet in width and lattice
towers. Standards for the installation of each type of antenna
are as follows:
(aa) Wall Mounted Antenna. The following provisions
apply to Wall Mounted Antennas:
(1) Wall mounted antennas shall not extend
above the wall line of the building or extend
more than four (4) feet horizontally from the
face of the building.
(2) Antennas, equipment and the supporting
structure shall be painted to match the color
of the building or structure or the background
against which they are most commonly seen.
Antennas and the supporting structures on
buildings should be architecturally
compatible with the building. Whip antennas
are not allowed on a wall mounted antenna
structure.
Ord. 1-2-96 1
(3)
(3) Antennas mounted directly on existing
parapet walls, penthouses, or mechanical
equipment rooms, with no portion of the
antenna extending above the roofline of such
structures, shall be considered a wall
mounted antenna.
(bb) Roof Mounted Antenna. The following provisions
apply to Roof Mounted Antennas:
(1) Roof mounted antennas shall be allowed on
top of existing penthouses or mechanical
equipment rooms provided the antennas and
antenna support structures are enclosed by a
structure that creates a visual screen. The
screening structure, antennas and antenna
mounting structures shall not extend more
than eight (8) feet above the existing roofline
of the penthouse or mechanical equipment
room.
(2) For antennas not mounted on a penthouse or
mechanical equipment room, the antennas
shall be mounted at least five (5) feet from the
exterior wall of a building. For antennas
mounted between five (5) and ten (10) feet
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 (10) feet above the roofline of
the building to which the antenna is attached.
Antennas shall be mounted at least five (5)
feet behind any parapet wall. For antennas
mounted between (5) five and ten (10) feet
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 of ten (10) feet as measured
from the top of the parapet wall. The
antennas shall not extend more than fifteen
(15) feet above the roofline of the building
itself unless approved as a conditional use
(see figure 2). Roof mounted antennas shall
not extend above the roofline of any
penthouse or mechanical equipment room
unless approved as a conditional use.
Roof mounted antennas are permitted only on
a flat roof and shall be screened, constructed
and/or colored to match the structure to which
they are attached.
Ord. 1-2-96 2
(cc) Monopole with Antennas and Antenna Support
Structure Less Than 2 (Two) Feet in Width. The total
antenna structure mounted on a monopole shall not
exceed two (2) feet in width. The maximum height of
such antenna shall not exceed ten (10) feet in height
(see figure 3 ). No such antenna shall be located
within 165 feet of a residential zone other than the R-
MU district.
(dd) Monopole With Antennas and Antenna Support
Structure Greater Than 2 (Two) Feet in Width. The
maximum visible width of antennas and antenna
mounting structures on a monopole shall not exceed
eight (8) feet in height or thirteen (13) feet in width
as viewed looking directly at the monopole at same
elevation as the antennas and antenna mounting
structure (see figure 4 ). No such monopole shall be
located within 330 feet of a residential zone other
than the R-MU district.
(ee) Lattice Tower. -The maximum visible width of
antennas and antenna mounting structures on a lattice
tower shall not exceed eight (8) feet in height or
thirteen (13) feet in width as viewed looking directly
at the monopole at the same elevation as the antennas
and antenna mounting structure (see figure 5 ). No
such lattice tower shall be located within 330 feet of a
residential zone.
(3) Height Limit. The height limit for monopoles and lattice
towers is identified in Table 1.
(4) Location and Minimum Setbacks. Monopoles with antennas
and antenna support structure less than two (2) feet in width,
monopoles with antennas and antenna support structure
greater than two (2) feet in width and lattice towers shall be
allowed only in the rear yard area of any lot. These
structures shall not be located in a required landscaped area,
buffer area or required parking area.
(5)
Area Limitations 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 160 square feet per building. A
maximum of four (4) walls shall be occupied by cellular
antennas. The total area is the sum of the area of each
individual antenna face and the visible portion of the
supporting structure as viewed when looking directly at the
face of the building. The total area for a roof mounted
antenna shall apply to the closest exterior wall (see figure 1).
Ord, 1-2-96 3

(8) Roof and Wall Mounted Antennas on Noncomplying
Buildings that Exceed the Maximum Height Limit of the
Zoning District. Wall mounted antennas shall be a permitted
use on noncomplying buildings that exceed the maximum
height limit of the zoning district in which they are located.
Roof mounted antennas which are mounted on a
noncomplying building above the maximum height limit of
the zoning district require conditional use approval.
Additional Conditional Use Requirements. In addition to
conditional use standards outlined in Chapter 27,
Conditional Uses, the following shall be considered by the
Planning Commission:
(aa) Compatibility of the proposed structure with the
height and mass of existing buildings and utility
structures.
(bb) Whether co -location of the antenna on other existing
structures in the same vicinity such as other towers,
buildings, water towers, utility poles etc. is possible
without significantly impacting antenna transmission
or reception.
(cc) The location of the antenna in relation to existing
vegetation, topography and buildings to obtain the
best visual screening.
(dd) Whether the spacing between monopoles and lattice
towers creates detrimental impacts to adjoining
properties.
(10) Accessory Buildings to Antenna Structures. Accessory
buildings to antenna structures must comply with the
required setback, height and landscaping requirements of the
zoning district in which they are located. Monopoles shall be
fenced with a six (6) foot chain -link fence and the climbing
pegs removed from the lower 20' of the monopole. All
power lines on the lot leading to the accessory building and
antenna structure shall be underground.
(11) Historic Districts. Any antenna proposed for a location
within a historic district or on landmark site is subject to
approval through the Historic Landmarks Commission as
contained in Part III, Chapter 17.
(12) Permission required for Antennas and Mounting Structures
on or over a public right-of-way. Antennas and mounting
structures encroaching on or over the public sidewalk or on
or over a public right-of-way shall be subject to obtaining
permission from the City pursuant to the City's Rights -of -
Way Encroachment Policy.

equipment used primarily for the transmission, reception or transfer of voice or data
through radio wave or (wireless) transmissions. Such sites typically require the
construction of transmission support structures to which antenna equipment is attached.
MONOPOLE WITH ANTENNAS AND ANTENNA SUPPORT STRUCTURE
GREATER THAN TWO (2) FEET IN WIDTH. A self supporting monopole tower on
which antennas or an antenna structures exceeding two (2) feet in width are placed. The
antennas and antenna support structures may not exceed thirteen (13) feet in width or eight
(8) feet in height.
MONOPOLE WITH ANTENNAS AND ANTENNA SUPPORT STRUCTURE LESS
THAN TWO (2) FEET IN WIDTH. A monopole with antennas and antenna support
structure not exceeding two (2) feet in width. Antennas and antenna support structures may
not exceed ten (10) feet in height.
MONOPOLE. A single cylindrical steel or wooden pole that acts as the support structure
for antennas.
ROOF MOUNTED ANTENNA. A roof mounted antenna is an antenna or series of
individual antennas mounted on a flat roof, mechanical room or penthouse of a building.
WALL MOUNTED ANTENNA. An antenna or series of individual antennas mounted
against the vertical wall of a building.
WHIP ANTENNA. An antenna that is cylindrical in shape. Whip antennas can be
directional or omnidirectional and vary in size depending upon the frequency and gain for
which they are designed.
