Proposal
To install three additional antennas on an extended existing wood monopole for a total height of 8.2' above the
height of the reference tree to accommodate the addition of 4G services.
Context
The existing pole is located approximately 480' from the Rt. 29 right -of -way and next to an nTelos facility.
Both facilities are located at the edge of a wooded area. Between the wooded area and the EC are a residence
with outbuildings and open lawns. Driveways lead to the facility and the residence.

PROJECT DETAILS
• Increase the height of a telecommunications facility to accommodate the attachment of new antennas; the top of the new antennas
would be 94.2' AGL; existing top of antennas is 85.75' AGL; pole height would be 8.2' above the top of the reference tree (an 86' tall
15" diameter poplar with a drip line approximately 4' away from the pole).
• New antennas would be attached to the pole using a cluster -mount system.
• Pole- and ground- mounted equipment is to be painted SW 6090 java brown.
• The concrete pad would be extended to accommodate the new ground equipment.
• Existing antennas do not fully clear the surrounding tree canopy.
• Proposed antennas measure 7' 10.6" tall x 11.2" wide x 4.5" deep.

ANALYSIS FOR THE CERTIFICATE OF APPROPRIATENESS FOR THE GROUND EQUIPMENT AND BASE STATION
A Certificate of Appropriateness from the ARB is required for the base equipment portion of a proposed telecommunications facility in the
Entrance Corridors. 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.

ANALYSIS REGARDING VISIBILITY OF THE MONOPOLE
The ARB may act in an advisory capacity to the Planning Commission on the Planning Commission's determination as to whether the
facility is being sited to minimize its visibility.

are not expected to have any additional impact on the EC.
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.
Regarding visibility of the monopole:
Staff recommends that the ARB forward the following recommendation to the Planning Commission:
The ARB finds that the proposed location of the facility will sufficiently minimize the visibility of the extended monopole from
the Entrance Corridor.
