Proposal
To install a treetop tier III personal wireless service facility consisting of a 106' tall monopole with antennas and
associated equipment in a 1,350 sf lease area.
Context
The subject parcel contains a house, several outbuildings, and an existing telecommunications facility. The
surrounding context is rural in character.
Visibility
The tower site is located over 900' from the Entrance Corridor street. Distance, trees along the EC frontage, and
topography limit views from vantage points along the parcel frontage. The balloon was viewed through trees from a
vantage point on Rt. 20 a short distance north of the parcel, and at Carter's Bridge.

HISTORY
There is an existing treetop tower at this site. An ARB application was submitted for that tower in 2008. At the balloon test for that application, it was
determined that the pole and equipment would not be visible from the Entrance Corridor. Consequently, ARB review and approval were not required.
PROJECT DETAILS
•
Proposed tower location is over 900' east of Rt. 20.
•
Reference tree is a Poplar with a 28" diameter and 95' height (628.55' AMSL).
•
Establish a 1350 square foot (30' x 45') lease area at 531' AMSL accessed by existing entrance on Rt. 20 and existing gravel drive.
Only a short extension of the existing gravel drive is necessary for access.
•
Establish a 20' x 35' wood -fenced compound.
•
Install a 106' -tall monopole; base at 531.21' AMSL, top at 637.21' AMSL.
•
Install a 149.28 sf covered steel platform for equipment cabinets, transmitter, generator and other equipment.
•
Install 1 array, consisting of 6 remote radio heads and 6 antennas, mounted such that the back of the antennas shall not be more than 1'
2-7/16" from the face of the monopole.
•
Proposed antennas measure almost 8' tall x 1' 2" wide x 8.2" deep.
•
Pole, antennas and base station equipment to be painted SW 6090 java brown.
ANALYSIS REGARDING THE GROUND EQUIPMENT
A Certificate of Appropriateness from the ARB is required for the base equipment portion of this proposed telecommunications facility in the Entrance
Corridor. The ARB may impose conditions on the Certificate of Appropriateness, based on the EC Guidelines, and consistent with Section 5.1.40 of the
Zoning Ordinance.

SUMMARY OF RECOMMENDATIONS
Regarding the Certificate of Appropriateness for the ground equipment and base station:
Because the proposed facility is consistent with all applicable guidelines, staff recommends approval of the Certificate of Appropriateness, as
proposed, for the ground equipment and base station.
Reuardine visibilitv of the monopole:
Staff recommends that the ARB forward the following recommendation to the Agent:
The ARB finds that the facility is expected to have minimal visibility and is not expected to have a negative visual impact on the Entrance
Corridor. However, the following revisions to the plans are required for accuracy:
1. Revise the note on Sheet C5 that reads "proposed light pole" to read "proposed monopole".
2. Revise the note on Sheet C5 to indicate that the distance from the back of the antenna to the face of the pole is 1' 2-7/16".
