ARCHITECTURAL REVIEW BOARD STAFF REPORT Project #/Name ARB-2017-73: Stony Point Volunteer Fire Co. PWSF Tier 3 Review Type Advisory Review Parcel Identification 048000000018DO Location 3829 Stony Point Road Zoned Village Residential (VR)/Entrance Corridor (EC) Owner/Applicant Stony Point Volunteer Fire Co./Milestone Communications (Lori Schweller, Esq.) Magisterial District Rivanna Proposal To establish a telecommunications facility consisting of a 135' steel monopole with associated equipment. Context The subject parcel lies within the Southwest Mountains Rural Historic District. The surrounding area is generally rural in nature, with single-family residences, the fire station, and the Stony Point School nearby. Visibility See page 3. ARB Meeting Date September 18, 2017 Staff Contact Margaret Maliszewski HISTORY The ARB reviewed a proposal for a 109.5' tall monopole with associated equipment on this parcel on July 15, 2013. The proposed location was to the northeast of the existing structures, approximately 400' north of the current proposal. That facility was approved but has not been constructed. 19:Z1a1BE" 811DIW.1Iski • The proposed tower location is approximately 656' east of Rt. 20. • A gravel drive approximately 550' long would be created from the existing paved parking area through wooded area to the tower compound site. • A 50' x 50' fenced compound is proposed. • The proposed fence is an 8'-high chain link fence with 1' barbed wire. • The proposed monopole is a tapered 135'-tall galvanized steel pole. The base of the pole is at 480' AMSL and the top is at 615' AMSL. • One array of 3 antennas with 6 remote radio heads and 1 microwave antenna would be installed at the top of the pole. Proposed pole height allows for three additional arrays. • Antennas are proposed to be mounted with the closest point of the back of the antenna 18" from the face of the pole. • Proposed antennas measure 72.8" tall x 7.1" deep x 11.9" wide. • Various pieces of equipment and a steel platform would be installed within the compound. The compound is large enough to accommodate four lease areas for future users. • The pole and antennas would be painted SW 6090 Java brown. • Special Exceptions are requested as outlined in the following table. Standard Requirement Special Exception Requested Applicant's Reasoning Staff Comment 5.1.40.b(2)(a) Request for four arrays. The applicant states that Because the antennas must be above tree Number of arrays is limited to larger carriers using flush- level to function fully, the ability to install three. mounted antennas would four arrays implies the use of a taller pole, require at least two positions and a taller pole potentially means greater on the monopole to provide visibility. However, the balloon test showed services. Four arrays would limited visibility of the pole at the maximize the use of the requested height. Consequently, with the facility. tree cover viewed during the balloon test, the additional array is not expected to have significant additional impact. 5.1.40.b(2)(c) Request to allow antennas to be The applicant states that the Staff agrees that the additional 6" of Projection shall be no greater than attached to mounting frames with mounting components will projection is not expected to be noticeable 12" from facility to closest point projection 18" from facility to not allow for the 12" from the vantage points where the balloon of back of antenna and no greater closest point of back of antenna.

However, specifying an than 18" to furthest point of back maximum distance from facility to additional 6" is not expected appropriate maximum distance from facility of antenna. furthest point of back of antenna has to be noticeable from the to furthest point of back of antenna would not been specified. ground. provide greater certainty regarding the appearance of future installations. 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 None. visibility from the Entrance Corridor street: Rt. 20 Entrance Corridor due to the distance from the street e) Mechanical equipment and wooded area to remain around the compound. 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. Ref Guideline Issues Recommendations Development pattern 33 The relationship of buildings A balloon test was conducted on August 22, 2017 for this proposal. The Route Given the extremely limited and other structures to the 20 Entrance Corridor (as well as Rt. 784/Watt's Passage, November Hill Farm degree of visibility displayed Entrance Corridor street and road, Sacre Meadow Lane, and Merrie Meadows Lane) was traveled to at the balloon test, the to other development within determine visibility. The balloon was visible for an approximate distance of proposed location of the the corridor should be as 1400' on Rt. 20 adjacent to and south of the fire station property. The balloon facility is expected to follows: was alternately visible through existing trees and above the trees at vantage sufficiently minimize the f. The placement of points approximately 650' — 1300' west and southwest of the proposed tower visibility of the monopole structures on the site should site. 36 trees are proposed to be removed from the site to accommodate the from the Route 20 EC such respect existing views and access road and lease area. This is a substantial quantity of trees; however, a that no negative impact on the vistas on and around the site. substantial number of trees to remain are also shown between the site and the Entrance Corridor is EC, as is additional area labeled generally as "existing wooded area". It is anticipated. anticipated that the trees to remain will sufficiently minimize visibility, consistent with the view during the balloon test. Re . ag rding 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. ReLyardine visibilitv 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. 2. The ARB has no objection to the requests for the special exceptions with the condition that an appropriate maximum distance from facility to furthest point of back of antenna be provided. 24" is recommended.
