Context The subject parcel lies on the south side of Rockfish Gap Turnpike with Wild Turkey Lane nearby on the west (Figure 1). Visibility See page 3. ARB Meeting Date February 3, 2020 Staff Contact Khristopher Taggart HISTORY and PROJECT DETAILS January 16, 2020: A balloon test was conducted. The balloon was flown at 116.7' above ground level. December 12, 2007: A Certificate of Appropriateness was approved for ARB-2007-33, a proposal for a steel monopole, equipment pad, and associated equipment in a 25'x30' lease area. Conditions of approval were related to a reduction of the pole height to 98' maximum and color of the pole. The monopole has been installed. May 3, 1999: A Certificate of Appropriateness was approved for ARB-1999-13, a proposal for a wood monopole. Conditions of approval were related to the material/color of the pole and equipment, and a requirement for no fencing. The monopole has been installed. 560-1& 56G-21 56G-38 56G-22 \p�� 56G 393' S6'IG4F � 56'6 56G-49 56G S~�� 56G-46 b- G. 56G 7 1'� � 56-1OOG 56G-6 56G 56G-4a Uh r 56G-5 'x� 56- 00 56G-4 "' a-, 5H�G �5�G-A 1 5 6G-A 5 7-41 C; 56G 53 56-99 56G-54 56G-1 57-39 5 6-102 56-104+ \56-101, 5 6-105 f 5 6-114A J 56-114B 5 6-102 B jf 565 6-162A 56-112 5 6-114B2 /56-114BS 56-T14B6 F7_AI Figure 1: Proposed site location along Rockfish Gap Turnpike. The monopole is proposed to be located 28.5' south of the property line along Route 250 West, approximately 46' northwest and 72' southwest of the existing monopoles on site, approximately 114' east of Wild Turkey Lane, and approximately 130' northwest of the existing residence. A number of deciduous trees are located in the yard, with the proposed pole location approximately 36' from a large White Oak. A substantial vegetated area exists along the right-of-way between the property and the Entrance Corridor. A 900-square-foot rectangular proposed lease area contains a 25-foot by 30-foot (750 square foot) compound area that is enwalled by a board -on -board fence. A proposed radio transmitter cabinet atop a concrete pad, a 10-foot-wide utility H-frame stand for power and communications components atop a steel grated platform, an emergency generator atop a second concrete pad, and an ice guard will lie within the enclosed area. The proposed wooden fence is 8 feet in height from grade; any base station equipment that may extend above the screening fence will be painted Sherwin Williams "Java Brown" (SW#6090). No guy wires are proposed, and a single LED floodlight mounted to the utility H-frame will only be used as needed. 2 Access will be provided through a 12-foot-wide gate on the southern elevation of the fence. An existing gravel driveway located on the parcel will be extended approximately 60 feet northwestward, creating a 12-foot wide access road to the proposed facility. It appears that only two extant trees over six inches in caliper are to be removed from within the lease area. However, tree removal information in the drawings is inconsistent. The tree inventory table marks trees 155 and 167 with an asterisk for removal, but the notes at the end list 155 and 242 as to be removed. Proposed work is centered over trees 155 and 167. The monopole, measuring 30 inches in diameter at its base and tapering to 18 inches in diameter at its top, is made of galvanized steel, the base of the pole is at 667.3' AMSL while the top of the pole is 784' AMSL (786' AMSL including the lightning rod). The monopole and antennas will be painted Sherwin Williams #6090 "Java Brown," a matte enamel color which has been previously approved on similar "treetop" PWSF monopoles in Albemarle County. A mounting collar and frames will allow for six antennas in a single array within three horizontally separated sectors with centerline at 113 feet AGL. The average antenna dimensions are 96.0" H x 11.9" W x 7.1" D = 1142.4 square inches. They will project 18" from the face of the monopole, and because of such, will require a Special Exception as outlined in the following table.

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. Ref Guideline Issues Recommendations Accessory structures and equipment 17 The following should be screened to eliminate The ground equipment is not expected to be visible from the Revise the proposed fence visibility from the Entrance Corridor street: Route 250 West Entrance Corridor due to topography and design to a 3-board fence. e) Mechanical equipment existing trees. However, a portion of the proposed 8'-tall, 25- foot by 30-foot board -on -board fence is expected to be visible from the Entrance Corridor. This fencing is not consistent with the 3-board fencing located around the existing tower compounds and along the EC. Maintaining a consistent fence design would provide a compatible appearance. ANALYSIS REGARDING VISIBILITY OF THE FACILITY The ARB may act in an advisory capacity to the Agent as to whether the facility is being sited to minimize its visibility.

SUMMARY OF RECOMMENDATIONS Regarding the Certificate of Appropriateness for the ground equipment and base station: Staff recommends approval of the Certificate of Appropriateness with the following condition: 1. Revise the proposed fence design to a 3-board fence. Regarding visibility of the monopole: Staff recommends that the ARB forward the following recommendation to the Agent: 1. The ARB finds that the proposed location will sufficiently minimize the visibility of the monopole from the Entrance Corridor. Regarding recommendations on the plan: 1. Correct and coordinate information on tree removal. 2. Correct discrepancies with the Drawing Index.
