Approximate location of monopole
Approximate location of equipment compound
These next few slides will summarize the variances being requested.
The monopole tower is proposed to replace an existing light standard that is located approximately 10 feet from
the southern property line which currently abuts residential property. The proposed equipment compound is located on the adjacent lot to the east that abuts a commercial lot to the south
that has a significant existing tree buffer along the common property line. A landscape buffer of plant materials is required around tower facilities and any equipment buildings. Due
to the proposed configuration, the existing conditions of the site and surrounding properties, the applicant is requesting relief from landscaping requirements.

Access Easement
One (1) all weather surface parking space shall be provided on each site. The applicant is proposing an access easement that utilizes an existing driveway off E. Highland St. and continues
down through the sports field area to the lease area. The applicant is requesting to keep the current condition of the site as much as possible and states the occasional access to the
site will not require a separate parking space from the existing parking.
15
Variance – Co-location
Variance to co-location requirement under Zoning Ordinance No. 480, Section 45.7.d.2.b
The proposed tower facility does not allow for additional providers due to the limited space available on the pole which also serves as a sports field light standard.
16
Variance – Setback
Variance to setback requirement under Zoning Ordinance No. 480, Section 45.7.d.7.a, c:
Towers shall be a minimum of 200 feet or 2:1 distance to height ratio, whichever is greater,
from the property line of properties used for residential purposes.
Towers shall be located in such a manner that if the structure should fall along its longest dimension, it will
remain within property boundaries and avoid habitable structures, public streets, utility lines and other telecommunication towers.
The proposed location of the monopole is approximately 10 feet from the property line directly to the south and approximately 100 feet from the property line south of the first line.
The
monopole is approximately 95 ½ feet in height. If the monopole should fall, it would not remain within the subject property boundary, however, the nearest habitable structure is approximately
108 feet away.

Proposed Extended Monopole Rendering
115.6’
95.6’
72.1’
Following the recommendation by the Planning & Zoning Commission, the applicant has provided a rendering showing the extended height it would require in order to accommodate an additional
provider. The existing light pole is 72.1 feet in height. The original proposal was to add 23.5 feet (total 95.6 feet) to accommodate Verizon Wireless’ antennas. In order to add a
second carrier the applicant would need to add another 20 feet to the antenna structure for a total of 115.6 feet. Verizon uses two canisters or two levels of antennas. Assuming a
second carrier would use the same two more levels of canisters would need to be added to hold their antennas. Verizon Wireless agrees to build the site with 4 levels of canisters to
accommodate Verizon Wireless and another carrier.

This slide shows option 1 which was presented to P&Z. The light rack is located at the same elevation as on the previous light pole. The extension containing the two Verizon antennas
is approximately 20’ in height.
The diameter of the existing light pole is 18 ½ inches. The diameter of the proposed monopole is approximately 44 inches at the base and gradually gets
smaller to about 33 inches at the top. The ordinance allows for up to 48 inches in diameter for monopoles.

Option 2
135’
93’
This slide shows option 2 showing the extension recommended by P&Z. The additional extension added 20’ in height and can accommodate two additional antennas by another carrier.
The
diameter of the existing light pole is 18 ½ inches. The diameter of the proposed monopole is approximately 44 inches at the base and gradually gets smaller to about 33 inches at the
top. The ordinance allows for up to 48 inches in diameter for monopoles.
