99SN0203April 28, 1999 BS REQUEST ANALYSIS AND RECOMMENDATION 99SN0203 Triton PCS Inc. Dale Magisterial District North line of Courthouse Road REOUEST: Conditional Use Planned Developmem to permit a communications tower and height exception in a Residential-Townhouse (R-TH) District. PROPOSED LAND USE: A 100 foot communications tower and associated improvements are planned. PLANNING COMMISSION RECOMMENDATION RECOMMEND APPROVAL SUBJECT TO THE CONDITIONS ON PAGES 2 AND 3 AND ACCEPTANCE OF THE PROFFERED CONDITION ON PAGE 4. STAFF RECOMMENDATION Recommend approval for the following reasons: Ao The proposed tower site lies within the boundaries of the Central Area Land Use Plan which suggests the request property and surrounding area are appropriate for light industrial and mixed use corridor uses. The Guidelines for Planning Commission Review of Substantial Accord Determinations and/or Zonine Am)royal for Communications Tower Locations suggests that communications towers should generally be located away from areas of existing or anticipated development and high visibility areas, such as along major roads, or otherwise be designed to minimize the visual impacts of the tower on such anticipated areas of development and traffic corridors. The tower site consists of a densely wooded property that includes enough acreage to accommodate a buffer of mature trees and is further located a minimum of 1,300 feet from Route 288, 800 feet from Iron Bridge Road, 550 feet from Courthouse Road, 600 feet from an adjacent office building and 570 feet from residences along Courthouse Road. Subject to the recommended buffer condition, the 100 foot height limitation and the applicant's proffered treatment of the tower and antennas, the tower site generally conforms to the siting criteria of the Guidelines. Although the request property is part of a ten (10) acre tract zoned for residential- townhouse use, this property and adjacent, industrially zoned property to the north and west have been identified as having a high percentage of wetlands. Given the identified wetlands, the tower site should remain relatively remote from anticipated future area development. Do The applicant has submitted documentation indicating that this tower should not adversely affect the operations of the Chesterfield County Airport. The conditions recommended herein, together with the applicant's proffered condition, will further minimi?e the possibility of any adverse impact on existing or future area development, as well as on the Chesterfield County Public Safety Trunked System. (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. There shall be no signs permitted to identify this use. (P) (STAFF/CPC) 2. The base of the tower shall be enclosed by a minimum six (6) foot high fence, designed to preclude trespassing. A detailed plan depicting this requirement shall be submitted to the Planning Department for approval in conjunction with final site plan review. (P) (STAFF/CPC) 3. The tower and equipment shall be designed and installed so as not to interfere with the Chesterfield County Public Safety Trunked System. At the time of site plan review, the owner/developer shall submit information as deemed necessary by the Chesterfield County Communications and Electronics staff to determine if an engineering study should be performed to analyze the possibility of radio frequency interference with the County system, based upon the frequencies and effective radiated power generated by tower- mounted equipment. Prior to release of a building permit the study, if required, shall be submitted to, and approved by, the Chesterfield County Communications and Electronics staff. (GS) 2 99SN0203/WP/APR28J (STAFF/CPC) (STAFF/CPC) (STAFF/CPC) (STAFF/CPC) (STAFF/CPC) (STAFF/CPC) o o The developer shall be responsible for correcting any frequency problems which affect the Chesterfield County Public Safety Trunked System caused by this use. Such corrections shall be made immediately upon notification by the Chesterfield County Communications and Electronics staff. (GS) All driveways and parking areas shall be graveled or paved and maintained to minimize dust problems and provide ease of ingress and egress. (P) With the exception of the tower and antennas or other tower- mounted equipment, any building and/or mechanical equipment shall comply with Sections 19-590 (b) and (c) and 19-595 of the Zoning Ordinance relative to architectural treatment of building exteriors and screening of mechanical equipment. (P) (Note: This condition would require screening of mechanical equipment located on the building or ground from adjacent properties and public rights of way. Screening would not be required for the tower or tower-mounted equipment.) At such time that the tower ceases to be used for communications purposes for a period exceeding twelve (12) consecutive months, the owner/developer shall dismantle and remove the tower and all associated equipment from the property. (P) A minimum 100 foot buffer shall be maintained around the perimeter of the tower site. Except for access and utilities, which may be extended generally perpendicular through this buffer, existing healthy trees having a minimum caliper of 2.5 inches or greater within this buffer shall be preserved and maintained. These trees shall be supplemented where necessary to minimize the views of the tower and associated equipment from adjacent properties and public rights of way. Additional plantings shall consist of trees of species having an average minimum mature crown spread of greater than thirty (30) feet and a minimum caliper of 2.5 inches at the time of planting, to achieve minimum density of one (1) tree for each 300 square feet of cleared area. At the time of site plan review, a landscaping plan depicting this requirement shall be submitted to the Planning Department for approval. (P) In conjunction with the approval of this request, a fLC~y (50) foot exception to the fifty (50) foot height limitation for towers in Residential-Townhouse (R-TH) Districts shall be granted. (P) 3 99SN0203/WP/APR28J PROFFERED CONDITION (STAFF/CPC) The treatment, color, lighting system and design of the tower shall be as follows: (a) The tower shall be grey or another neutral color, acceptable to the Planning Department. Co) The tower shall not be lighted unless lighting is required by FAA. If lighted, tower lighting during daylight hours shall be limited to medium intensity strobe lights with upward reflection and lighting during night-time hours shall be limited to soft blinking lights. (c) The tower shall be of a monopole design. (d) Antenna(s) on the tower shall be limited to "cluster mounted" or "flush mounted" antenna(s) as depicted on the plan entitled "Flush Mounted Antennae" and dated February 4, 1999, or whip antenna(s). (P) GENERAL INFORMATION Location: North line of Courthouse Road across from Fallow Drive. Tax ID 767-666-Part of 7026 (Sheet 22). Existing Zoning: R-TH with Conditional Use Planned Developmem Size: 3.5 acres Existing Land Use: Vacant 4 99SN0203/WP/APR28J Adjacent Zoning & Land Uses: North - I-1 with Conditional Use Planned Developmem; Vacam South - R-15, R-TH with Conditional Use Planned Development and C-3; Single family residential or vacant East - C-2 with Conditional Use Planned Development; Office West - R-TH with Conditional Use Planned Development; Vacam The tower and associated equipment will not require the use of the public water and wastewater systems. ENVIRONMENTAL Drainage and Erosion: No existing or anticipated on- or off-site drainage or erosion problems with the · improvements to accommodate the tower. A land disturbance permit is not required if less than 2,500 square feet of land area is disturbed by the constmction of the tower and associated improvements. PUBLIC FACILITIES Fire Service and Transportation: This use 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 communication system; however, as a further precaution, if this request is approved, 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 Tmnked System (Condition 3). Once the tower is in operation, if interference occurs, the owner/developer should be required to correct any problems. (Condition 4) 5 99SN0203/W-P/APR28J COUNTY AIRPORT The applicant has submitted an FAA determination that the proposed tower will conform with FAA requirements relative to tower height and design for towers in proximity to the Chesterfield County Airport. Therefore, it is anticipated that the proposed tower should not pose a hazard to air navigation nor interfere with the operation of the Chesterfield County Airport. Comprehensive Plan: The request property lies within the boundaries of the Central Area Land Use Plan w?fich suggests the property is appropriate for light industrial use. Area Development Trends: Area developmem is characterized by office, public/semi-public and commercial uses along Iron Bridge Road, transitioning to residential uses along the south line of Courthouse Road, west of Iron Bridge Road, and by vacant, industrially zoned property along the north line of Courthouse Road, west of Iron Bridge Road. This vacant, industrially zoned property, together with the request property and adjacent, commercially zoned property to the east, are part of a mixed use development approved in 1981 (Halinda). Much of this property may be impacted by potential wetlands. However, it is anticipated that should development occur it would consist of a mix of office, commercial, residential and industrial uses, in accordance with the zoning approval for Halinda. The tower site consists of an acreage parcel lying adjacent to the parking lot of an existing office building. Access would be provided via a driveway to Courthouse Road. The request property is heavily wooded. Given the potential visibility of the proposed tower, the tower enclosure should be located on the request property where existing, mature vegetation can serve to minimize the view of the tower from area residences and public rights of way (Condition 8). In addition, the applicant has proffered that antennas would be limited to flush mounted sectored arrays or whip antennas, to further minimize the utilitarian appearance of the tower. (Proffered Condition) The Federal Aviation Administration may require lighting and/or markings so as to minimize possible air traffic hazards. Lighting should be designed so as not to adversely affect existing and future area development. (Proffered Condition) Consistem with past actions on similar facilities, the base of the tower should be secured with a fence to discourage trespassing. (Condition 2) 6 99SN0203/WP/APR28J 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 6). Specifically, imposition of Condition 6 would require that no building exterior which would be visible to any residential or agricultural district or any public right of way consist of architectural materials inferior in quality, appearance, or detail to any other exterior of the same building. There is, however, nothing to preclude the use of different materials on different building exteriors, but rather, the use of inferior materials on sides which face adjoining property. No portion of a building constructed of unadorned concrete block or corrugated and/or sheet metal could be visible from any adjoining residential or agricultural district or any public right of way. No building exterior could be constructed of unpainted concrete block or corrugated and/or sheet metal. Mechanical equipment, whether ground-level or rooftop, would have to be screened from public view and designed to be perceived as an integral part of the building. The views of junction boxes would have to be minimized from adjacent properties and public rights of way. However, it should be noted that imposition of Condition 6 would not require screening of the tower or tower-mounted equipment. 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 7) CONCLUSIONS The proposed tower site lies within the boundaries of the Central Area Land Use Plan which suggests the request property and surrounding area are appropriate for light industrial and mixed use corridor uses. In addition, the Guidelines for Review of Substantial Accord Determinations a.n.d/or Zoning Approval for Communications Tower Locations suggests that communications towers should generally be located away from areas of existing or anticipated development and high visibility areas, such as along major roads, or otherwise be designed to minimize the visual impacts of the tower on such anticipated areas of development and traffic corridors. The tower site consists of a densely wooded property that includes enough acreage to accommodate a buffer of mature trees and is located a minimum of 1,300 feet from Route 288, 800 feet from Iron Bridge Road, 550 feet from Courthouse Road, 600 feet from an adjacent office building and 570 feet from area residences along Courthouse Road. Subject to the recommended buffer condition, the 100 foot height limitation and the applicant's proffered treatment of the tower and antennas, the tower site generally conforms to the siting criteria of the Plan and Guidelines. Although the request property is part of a ten (10) acre tract zoned for residential-townhouse use, this property and adjacent, industrially zoned property to the north and west have been identified as having a high percentage of wetlands. Given the identified existing wetlands, the tower site should remain relatively remote from anticipated future area development. The applicant has also 7 99SN0203/WP/APR28J submitted documentation indicating that this tower, if approved, should not adversely affect the operations of the Chesterfield County Airport, and the conditions recommended herein, together with the applicant's proffered condition, 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. Given these considerations, approval of this request is recommended. CASE HISTORY Planning Commission Meeting (2/16/99): At the request of the applicant, the Commission deferred this case to March 16, 1999, to allow time for the applicant to meet with area property owners. Staff (2/17/99): The applicant was advised in writing that any significant new or revised information should be received no later than February 23, 1999, for consideration at the March 16, 1999, public hearing. The applicant was also advised that a $250.00 deferral fee must be paid prior to the March public hearing. Staff (2/23/99): To date, no new information has been submitted nor has the $250.00 deferral fee been paid. Applicant (3/1/99): The deferral fee was paid. Planning Commission Meeting (3/16/99): The applicant accepted the recommendation. There was opposition and support present. The Deerfield neighborhood indicated that the conditions and proffer coupled with the applicant's verbal agreement to landscape along the eastern boundary and install a gate at the entrance address their concerns. 8 99SN0203/WP/APR28J The property owner of the adjacent C-2 property to the east expressed concerns relative to the lack of buffers between the tower lease area and their property. It was requested that the site be located further from the C-2 property. Mr. Miller indicated that the applicant had attempted to address the issues and that a 100 foot buffer would be required around the tower site. On motion of Mr. Miller, seconded by Mr. Shewmake, the Commission recommended approval of this request subject to the conditions on pages 2 and 3 and acceptance of the proffered condition on page 4. AYES: Unanimous. Further, for the reasons stated herein, the Commission found this request substantially in accord with the Comprehensive Plan. The Code of Virginia, as amended, grants the Board the authority to "overrule the action of the Commission by a vote of the majority of the membership thereof'. The Board of Supervisors, on Wednesday, April 28, 1999, beginning at 7:00 p.m., will take under consideration this request. 9 99SN0203/WP/APR28J Z¢ _Z':/ C ZC Z¢ ROAD RD, .
