PLANNING COMMISSION: JULY 27, 2004
BOARD OF SUPERVISORS: SEPTEMBER 8, 2004
applicant proposes the installation of a personal wireless service facility,
which would include a metal monopole, approximately 80 feet in total height,
with a top height of approximately 524 feet Above Mean Sea Level (Attachment
A). This would result in a monopole that
is 10 feet taller in height than a nearby 72-foot tall tree identified on the
applicant’s construction plans. The
monopole would be equipped with one array of three 7.9-foot long by 8.1-inch
wide, flush-mounted panel antennas at its top.
Supporting ground equipment would be contained within two 5.5-foot tall and
4.5-foot wide cabinets on a 96 square foot concrete pad and a smaller cabinet
on a 5 square foot pad. The lease area
for the proposed facility is located on property described as Tax Map 92 Parcel
56B(3), containing 8.98 acres zoned RA Rural Areas and EC, Entrance Corridor
Overlay District (Attachment B). The

SP 00-44 Triton PCS (CVR 361A) - At it’s meeting on January 10, 2001, the Board of Supervisors unanimously approved a request to allow the installation of a personal wireless service facility on the subject parcel (Attachment C). A 78-foot tall wood monopole serves as the mounting structure for this facility.
SP 03-37 Moyer, Leroy and Helen (Triton PCS) - At it’s meeting on August 13, 2003, the Board of Supervisors unanimously approved a request to amend the existing special use permit by allowing the installation of additional ground equipment and the replacement of antennas supporting new digital technology and E-911 services.
Character of the Area:
The proposed site of the monopole for this facility is located in a wooded area approximately 78 feet south of State Route 53. The site is accessed by way of an existing gravel access road within an easement for the overhead utility lines that run parallel with the state right-of-way. Another line of trees runs between the easement and Route 53 providing additional camouflaging and screening of the existing facility. The area where the treeline starts is situated on an bank that is approximately 10 feet above the road at its highest point.
The two adjacent properties at the eastern and western and southern boundary lines with this site share common ownership with the subject parcel and are also zoned Rural Areas (RA). There is a single family dwelling on the parcel to the west and the nearest offsite dwelling is located approximately more than 204 feet to the north on property identified as Tax Map 92 - Parcel 36E. The 72-foot tall reference tree that is being used as the basis for the requested monopole height is located approximately 19 feet east of the monopole site and has a surveyed top elevation of 513.6 feet AMSL. The 78-foot monopole serving the existing Triton facility is 21 feet west of the proposed monopole site at the 448-foot contour interval. This means that the proposed 80-foot tall monopole, situated at 444 feet would be approximately 2 feet lower in total height AMSL.
a field visit staff observed that neither the existing monopole or the test
balloon was visible above the treeline from the Route 53 right-of-way (Attachment
D). Staff observed that the monopole was
only visible from Route 53 through the trees while standing directly in front
of the site. However, the tallest
portion of that monopole was visible, appearing as a minor extension of the tops
of the trees, while traveling south on
Because the proposed facility would be accessed by extending an existing road within a utility easement, staff does not anticipate that a substantial amount of earth disturbance will be necessary. Therefore, this request is being reviewed for compliance with the recommendations of the Comprehensive Plan that mainly focus on the visual impacts that could result from the presence of the facility’s monopole and equipment building.
The Personal Wireless Service Facilities Policy is the component of the Comprehensive Plan that provides specific guidelines for the siting and review of wireless facilities. Both the Open Space Plan and Chapter 2 of the Comprehensive Plan, entitled Natural Resources and Cultural Assets, provide staff with guidance for managing the County’s natural, scenic and historic resources, and for the preservation and conservation of those resources in order to protect the environment for future use.
Personal Wireless Service Facilities Policy:
The guidelines set forth in the Personal Wireless Service Facilities Policy are focused largely on reducing the visual impacts of wireless facilities from surrounding properties and roadways. The wireless policy recommends the implementation of a three-tiered approval system to address criteria related to the siting and design of new facilities. The first tier sets a preference for the development of “stealth” facilities that can either be completely concealed within existing structures, or attached to existing conforming structures. Tier Two calls for sites that can be designed to blend in well with the natural surroundings in a manner that assists in mitigating their visual impacts. This proposal qualifies as a Tier Two facility. The standard conditions of approval for Tier Two wireless facilities require the use of brown, treetop monopoles that extend no more than 10 feet above the tallest tree within 25 feet, and related ground equipment that is also painted brown.
Open Space Plan and Chapter 2:
Chapter Two of the Comprehensive Plan, entitled Natural Resources and Cultural Assets, provides guidance for protecting the County’s natural, scenic and historic resources, and sets the goals for preservation and management of those resources and the environment for future use. The Open Space Plan Concept Map provides an inventory that identifies the areas where the critical resources are present throughout the County. Some of the resources that have been identified as potentially being impacted by this request are historic sites and the entrance corridor overlay district for Route 53, and forests.
Although there are no surveyed historic sites identified on this parcel, staff recognizes that this site is located within the proposed Southern Albemarle Rural Historic District. Because State Route 53 is the main road connecting several of the nearby surveyed historic properties within the district, the Historic Preservation Planner has reviewed this proposal. The historic resources analysis concludes that the existing facility does not impose any significant negative impacts upon the district, but also includes general recommendations for assistance in lessening the possible impacts of the second facility at this site (Attachment E).
The intent of the Entrance Corridor Overlay District as stated in the Zoning Ordinance is, in part, “to implement the Comprehensive plan goal of protecting the county’s natural, scenic and historic, architectural and cultural resources, including preservation of natural and scenic resources as the same may serve this purpose,” and, “to protect the County’s attractiveness to tourists and other visitors; to sustain and enhance the economic benefits accruing to the County from tourism.” The Architectural Review Board addresses the aesthetic impact of all development within the Entrance Corridor Overlay Districts. The ARB has reviewed this proposal and recommends approval with conditions that are consistent with the design guidelines that are applied to all development within the entrance corridors (Attachment F). Based on this recommendation combined with fact that the test balloon could not be seen at its proposed height while traveling in either direction on Route 53, it is staff’s opinion that the proposed facility would not impose any negative visual impacts upon the entrance corridor.
The forests surrounding the proposed site of this facility are another resource that is recognized by the Open Space Plan as being present on the subject parcel. The Open Space Plan identifies forests within Rural Areas as large areas that are contiguous with other forests or farmlands, have the best soils for hard woods, and are not in subdivisions. When existing structures are not available, the recommendations set forth in the Personal Wireless Service Facilities Policy favor the practice of locating new facilities in forested areas where monopoles and ground equipment can be designed to blend in with the natural surroundings. This includes the preference for using brown structures that are no taller than the natural tree canopy so that they are not “skylighted” against the horizon or alter the continuity of ridgelines. Because of the limited amount of disturbance for the installation of this facility, and its distance from property lines, it is staff’s opinion that approval of this proposal would not greatly impact the naturally forested state of the subject parcel, or any of the neighboring properties within the area.
Staff has reviewed this request for compliance with the provisions of Section 126.96.36.199 of the Zoning Ordinance and recommends approval with the standard conditions of approval and some additional conditions that would be specifically applied to this proposal.
Staff will address the issues of this request in four sections:
1. Section 188.8.131.52 of the Zoning Ordinance; and,
2. Section 704 (a)(7)(b)(I)(II) of the Telecommunications Act of 1996.
1. Staff will address each provision of Section 184.108.40.206 of the Zoning Ordinance.
The Board of Supervisors hereby reserves unto itself the right to issue all special use permits permitted hereunder. Special use permits for uses as provided in this ordinance may be issued upon a finding by the Board of Supervisors that such use will not be of substantial detriment to adjacent property,
Staff notes that a concern for the proliferation of multiple wireless facilities within close proximity has been brought forth in the review of past proposals for horizontal co-location of more than one Tier II wireless facilities on a single property. The site of the proposed facility is in a wooded area surrounded by large trees that would assist in screening and camouflaging views from adjacent properties. The monopole serving this facility would be located only 21 feet from the existing Triton monopole. The previously approved facility is well-screened and the test balloon observation for the proposed facility indicates that the proposed facility would share some of the qualities that are favorable to it. Therefore, it is staff’s opinion that if designed and situated under conditions that are consistent with those for the existing facility, the proposed facility would not be an intrusive feature upon its natural surroundings or impose any substantial detriment to adjacent properties. This includes the installation of a wood monopole, as opposed a metal one.
that the character of the district will not be changed thereby,
The preservation of the agricultural and forestal lands and activities, and conservation of the natural, scenic and historic resources are listed among the stated purposes for the Rural Areas zoning district. Uses allowed by right in the in the Rural Areas are residential, and those related to agriculture and forestal activities, while uses allowed by special use permit are most often those that provide services in support of the by-right activities. However, support for locating facilities that comply with the recommendations of the Personal Wireless Service Facilities Policy has not been uncommon in the Rural Areas zoning district. The key purpose of the wireless policy is to site these facilities in locations where there is minimal potential for intrusion upon the naturally existing conditions in surrounding areas. It appears that the proposed facility in this particular case would blend well into the natural surroundings as a result of the tall trees surrounding the site.
Once the facility has been constructed and is fully operational, staff does not expect that the schedule of site visits would create a significant increase in activity or traffic within the area. As with past applications for personal wireless service facilities this would be an unmanned site and the applicant’s request indicates that service personnel would only have to travel to the site once a month for routine maintenance visits. It is also anticipated that some unscheduled visits will be necessary on occasions when electrical power for the site has been interrupted by unexpected occurrences such as adverse weather conditions. However, it is staff’s opinion that this schedule of infrequent site visits does not significantly increase traffic within the area.
Whenever requests to allow horizontal co-locations are being reviewed, staff attempts to ensure that the tree conservation plan for the existing facility is not altered to a point where the treeline and canopy providing camouflaging of the mounting structure and ground equipment is not compromised. The tree survey provided in the applicant’s construction plan packet proposes the removal of five trees (identified as numbers 270, 272,275, 277 and 279) ranging in between 22.7 and 40.5 feet in height, but none of these trees are tall enough or have a considerable amount of canopy to provide camouflaging of the existing or proposed facilities.
Based on the factors cited above, it is staff’s opinion that the character of the district would not be changed by the approval of the proposed facility.
and that such use will be in harmony with the purpose and intent of this ordinance,
Staff has reviewed this request with consideration for the purpose and intent of the Zoning Ordinance as stated in Section 1.4, and with further reference to Section 1.5.
Section 1.4.3 states, “To facilitate the creation of a convenient, attractive and harmonious community,” as an intent of the Ordinance. As evidenced by the expanded and rapid increase in their use, mobile telephones clearly provide a public service. The establishment of personal wireless service facilities expands the availability of communications opportunities and convenience for users of wireless phone technology. In the event of emergencies, access to the increased communication the opportunities provide wireless facilities can be consistent with the accepted principles of public health, safety and general welfare. Although wireless facilities are not often credited for enhancing the visual appearance of surrounding areas, the guidelines of the Wireless Policy are intended to ensure that the facilities are not responsible for intruding upon the important scenic resources that promote the attractiveness of the community.
Section 1.5 (Relation to Environment) states in part that the “ordinance is designed to treat lands which are similarly situated and environmentally similar in a like manner with reasonable consideration for the existing use, and character of properties, the Comprehensive Plan, the suitability of property for various use…; and preservation of flood plains, the preservation of agricultural and forestal land, the conservation of properties and their values and the encouragement of the most appropriate use of land throughout the County.” When they are designed and sited properly, personal wireless service facilities have not proven to be incompatible with any of the other agricultural and forestal objectives that are set forth for the Rural Areas.
The introduction of the second wireless facility within the immediate area through the approval this request would clearly increase the level of services that are available in the Rural Areas. However, because of the limited visibility of this site it is also staff’s opinion that if it is approved with the recommended conditions this request could be approved in harmony with the purpose and intent of the Zoning Ordinance.
with the uses permitted by right in the district,
Aside from restrictions on tree cutting within a certain distance of the facility, approval of this proposal would not act to restrict any of the established uses on the subject parcel, or the by-right uses allowed on other properties within the Rural Areas district.
with additional regulations provided in Section 5.0 of this ordinance, and with the public health, safety and general welfare.
Section 5.1.12a of the Zoning Ordinance contains regulations for locating public utility structures in a manner which “will not endanger the health and safety of workers and/or residents in the community and will not impair or prove detrimental to neighboring properties or the development of the same.” The Federal Communications Commission’s (FCC) regulations set forth in the Telecommunications act address the most significant concerns for public health and safety regarding personal wireless services. Staff has attempted to address the concerns for possible impacts upon neighboring properties in the area throughout this staff report and in the recommended conditions.
Section 5.1.40 of the Zoning Ordinance contains sets requirements for the submittal, review and approval of applications for personal wireless service facilities. When these regulations are combined with the recommendations of the Wireless Policy and standard conditions of approval, it is staff’s opinion that this special use permit could be issued in compliance with the provisions that state the concern for the public health, safety and general welfare.
2. Section 704(a)(7)(b)(I)(II) of The Telecommunications Act of 1996:
The regulation of the placement, construction and modification of personal wireless facilities by any state or local government or instrumentality thereof shall not prohibit or have the effect of prohibiting the provision of personal wireless services.
The Telecommunications Act addresses concerns for environmental effects with the following language, “No state or local government or instrumentality thereof may regulate the placement construction, and modification of personal wireless service facilities on the basis of the environmental effects of radio frequency emissions to the extent that such facilities comply with the Commissions’ regulations concerning such emissions.” In order to operate the proposed facility, the applicant is required to meet the FCC guidelines for radio frequency emissions. These requirements will adequately protect the public health and safety.
Neither the Comprehensive Plan nor the Zoning Ordinance prohibits the provision of personal wireless services. However, both do implement policies and regulations for the siting and design of personal wireless facilities. The applicant has not provided any information to demonstrate the availability, or lack thereof, of any alternative sites to serve the areas that would be covered by the proposed facility at this site. Therefore, it is staff’s opinion that the denial of this application would not have the effect of prohibiting the provision of personal wireless communication services.
Staff has identified the following factors, which are favorable to this request:
1. A test balloon floated at the proposed height of the monopole was only visible through the trees and below treetop level from Route 53;
2. The proposed monopole for this facility would be approximately 2 feet in total height AMSL than the existing Triton facility; and,
3. This site would be accessed from the gravel road serving the existing Triton facility.
The following factors are relevant to this consideration:
The top of the existing monopole is visible at treetop
2. This site is located within a proposed historic area; and,
3. There are existing and reasonable by-right uses that could be established on the subject property.
Staff has reviewed this request for compliance with the provisions set forth in Section 220.127.116.11 of the Zoning Ordinance and recommends approval with additional to the standard conditions, as applicable to this request.
(In the event that the Board chooses to deny this application staff offers the following comment:
In order to comply with the provisions of the Telecommunication Act, staff requests consensus direction from the Board regarding the basis for denial of the application and instruction to staff to return to the Board with a written decision for the Board’s consideration and action.)
