99sn0109.pdfDecember 16, 1998 BS REQUEST ANALYSIS AND RECOMMENDATION 99SN0109 Sprint PCS Clover Hill Magisterial District South line of Walmsley Boulevard REOUEST: Conditional Use Planned Development to permit a communications tower and height exception in an Agricultural (A) District. PROPOSED LAND USE: A communications tower with an initial height of 160 feet, plus accessory equipment, is planned. PLANNING COMMISSION RECOMMENDATION RECOMMEND APPROVAL SUBJECT TO THE CONDITIONS ON PAGES 2 THROUGH 4 AND ACCEPTANCE OF THE PROFFERED CONDITIONS ON PAGE 4. STAFF RECOMMENDATION Recommend approval for the following reasons: The proposed tower site lies within the boundaries of the Central Area Plan which suggests the request property and surrounding area are appropriate for residential use of 1.00 to 2.5 units per acre. The request site, however, is densely wooded and includes sufficient acreage to accommodate a buffer of mature trees around the tower enclosure, thereby minimizing views of the tower. Further, the applicant has proffered conditions which will further mitigate the tower's visual impacts. Subject to the recommended buffer condition and proffered conditions, the tower conforms to the siting criteria of the Public Facilities Plan and Guidelines for Review of Substantial Accord Determinations and/or Zoning Approval for Communications Tower Locations which suggests that communications towers should generally be located away from areas of anticipated residential development or otherwise be designed to minimize the visual impacts of the tower on such areas of development. The recommended conditions minimize the possibility of any adverse impact on existing or future area development, as well as on the Chesterfield County Public Safety Trunked System or the County Airport. (NOTE: CONDITIONS MAY BE IMPOSED OR THE PROPERTY OWNER MAY PROFFER CONDITIONS. THE CONDITIONS NOTED WITH "STAFF/CPC" WERE AGREED UPON BY BOTH STAFF AND THE COMMISSION. CONDITIONS WITH ONLY A "STAFF" ARE RECOMMENDED SOLELY BY STAFF. CONDITIONS WITH ONLY A "CPC" ARE ADDITIONAL CONDITIONS RECOMMENDED BY THE PLANNING COMMISSION.) CONDITIONS (STAFF/CPC) 1. A 100 foot buffer shall be maintained around the perimeter of the request site. Except for one (1) access driveway and utilities which may be extended generally perpendicular through this buffer, existing healthy trees 2.5 inches in caliper or greater within this buffer shall be preserved and maintained.

The owner/developer shall provide a copy of the notification letter to the Planning Department. (STAFF/CPC) 5. Height Limitation. The communications tower shall not exceed a height of 160 feet. (Note: Any tower in excess of 160 feet would require amendment of the Conditional Use Planned Development.) 4 99SN0109/WP/DEC 16H GENERAL INFORMATION Location: South line of Walmsley Boulevard, east of Summerbrook Drive. Tax ID 762-692-Part of 4200 (Sheet 15). Existing Zoning: A 1.7 acres Size: Existing Land Use: Vacant Adjacent Zoning & Land Use: North - A with Conditional Use; Public/semi-public (church) South - A; Single family residential East - A; Vacant West - A; Single family residential UTILITIES The proposed tower and associated equipment will not necessitate a manned facility; therefore, the public water and wastewater systems are not required. ENVIRONMENTAL Drainage and Erosion No existh~g or anticipated on- or off-site drainage or erosion problems. A land disturbance permit will not be required if less than 2,500 square feet of land area is disturbed by the construction of the tower and associated improvements. 5 99SN0109/WP/DEC 16H PUBLIC FACILITIES Fire Service and Transportation: The proposed tower and associated equipment will have a minimal impact on these facilities. County Communications: The Zoning Ordinance requires that any structure over eighty (80) feet in height be reviewed by the County's Public Safety Review Team for potential detrimental impacts the structure could have on the County's Radio Communications System microwave paths. This determination must be made prior to erection of the proposed communications tower. A preliminary review of this tower proposal has indicated that the facility will not interfere with the County's commmtication system; however, as a further precaution, a condition should be imposed to ensure that the tower is designed and constructed so as not to interfere with the Chesterfield County, Public Safety Trunked System (Condition 5). Once the tower is in operation, if interference occurs, the owner/developer should be required to correct any problems. (Condition 6) County.- Airport: A preliminary review of this tower proposal has indicated that the facility will not interfere with the operation of the County Airport; however, as a further precaution, if FAA approval is required, a copy of such approval should be submitted to the Planning Department prior to the release ora building permit. (Condition 4) LAND USE General Plan: The request property lies within the boundaries of the Central Area Plan which suggests the request property and surrounding area are appropriate for residential use of 1.00 to 2.5 units per acre. Area Development Trends: The request property is located in an area characterized by single family residences on acreage parcels, a church and by vacant, agriculturally zoned land. It is anticipated that area properties will eventually be zoned and developed for residential use. 6 99SNO109/WP/DEC16H The tower site consists of an acreage parcel lying approximately 450 feet south of Watmsley Boulevard. Access to the property will be provided via a driveway to Walmsley Boulevard. The request property is heavily wooded. Given the anticipated visibility of the proposed tower and its proximity to anticipated future area residential development and consistent with the Guidelines for Review and Approval of Towers, the tower should be located such that existing, mature vegetation can serve to minimize the view of the tower from area residences and public rights of way. (Condition 1) Given the proximity of existing and anticipated area residential development, the tower should not be lighted unless lighting is required by the FAA. (Condition 7.b.) Consistent with past actions on similar facilities, the base of the tower should be secured with a fence to discourage trespassing. (Condition 3) Architectural Treatment: The request property lies within an Emerging Growth Area. Given the potential for future development in the area, a condition should be imposed to require compliance with Emerging Growth requirements relative to architectural treatment of buildings and screening of mechanical equipment. (Condition 9) Given the potential for residential development in proximity to the tower site, the applicant has proffered that the tower will possess features designed to mitigate its utilitarian appearance and visibility (Proffered Conditions 1 and 2). Specifically, Proffered Condition 1 would require the tower to be of a monopole design. Proffered Condition 2 would require antenna mountings to extend no more than five feet, six inches (5' 6") from the tower. The applicant has also proffered to notify the last known contact or representative of the Route 360 Corridor Committee on file with the Planning Department of any future zoning request to increase the height of the tower over 160 feet. (Proffered Condition 4) The applicant has proffered to design and build the proposed tower and tower enclosure so as to accommodate a mininmm of four (4) cellular/PCS type wireless communications service providers (Proffered Condition 4). In this manner, the potential for tower proliferation along this portion of the Route 360 Corridor can be mininfized. Consistent with past actions on similar facilities, the tower should be removed at such time that it ceases to be used for communications purposes, to ensure that the tower does not become a maintenance problem or an eyesore. (Condition 10) 7 99SN0109/WP/DEC16H CONCLUSIONS The proposed tower site lies within the boundaries of the ~ which suggests the request property and surrounding area are appropriate for residential use of 1.00 to 2.5 units per acre. The request site, however, is densely wooded and includes sufficient acreage to accommodate a buffer of mature trees around the tower enclosure, thereby minimizing views of the tower. Further, the applicant has proffered conditions designed to further mitigate the tower's visual impacts. Subject to the recommended buffer condition and proffered conditions, the tower conforms to the siting criteria of the Puli -ties Plan and Guidelines for Review of Substantial Accord Determinations and/or Zoning Approval for Communications Tower Locations which suggests that communications towers should generally be located away from areas of anticipated residential development or otherwise be designed to minimize the visual impacts of the tower on such areas of development. In addition, the recommended conditions will further minimize the possibility of any adverse impact on existing or future area development, as well as on the Chesterfield County Public Safety Trunked System or the County Airport. Given these considerations, approval of this request is recommended. CASE HISTORY Applicant (9/3/98): The applicant requested a deferral to the Commission's October 20, 1998, meeting.
