HomeMy WebLinkAbout09-17 Comments (2)_mai r` Always connected to you RF Brief for Proposed Amherst Site # WAlSSH1.49 Frederick County, VA Is a hub to some of Virginia's major highways. Among these, 1-81 and Route 37 are the busiest roads carrying traffic north and south through the county to other nearby metropolitan areas. As the county progresses, the neighborhoods surrounding the intersection of Route 37 and Highway 50 are rapidly increasing the amount of data used by wireless devices. The continued growth in this part of Frederick County has stimulated the need for additional resources and infrastructure for wireless data access. This area is especially important because the existing site serves the many users at Valley Health Winchester Medical Center, Wal-Mart and the recently constructed restaurants, Virginia Department of Transportation Center, the Farmer's Livestock Exchange, and Spring Arbor Senior Living Center. There are also users at the Courtyard by Marriott hotel, as well as Candy Hili Campground, which has 100 plus campsites. Furthermore, the continued expansion of outpatient clinics at the medical center will create an even larger demand. Shentel currently operates a site collocated on a power pole in the interchange of southbound Hwy 37 off ramp, This installation has severe limitations due to the nature of the structure. This pole is a transmission tower and Is not capable of supporting the additional antennas and radios needed for upgrade. The proposed site will increase capacity and improve customer experience inside the buildings that are in this area. This proposed site is in the center of other sites that do provide offloading as well as some coverage to this area. The surrounding sites have all been upgraded with the additional technology and upgrading this location as proposed is extremely important to the network. The attached plots clearly show these surrounding sites and visually represents the need. Shentel, as well as the entire wireless industry, has seen an increase in data usage over the past few years that doubles every nine months. This is the case for the existing sites surrounding the proposed site location. These neighboring sites have experienced maximum usage resulting in slow data speeds or limited access. The proposed site (Site Number: WA15SH149) referred to as "Amherst" is located on the Bishop property at 219 Round Hill Road. The tower is to be placed In the rear behind the salvage yard and to the west of the Shenandoah Valley Electric substation. In conclusion it is evident from the data capacity analysis and the RF simulation map that the proposed replacement site WA15SH149 Amherst will improve data availability and in -building service. The proposed site at 138 feet will provide adequate in -building RF signal in this location and surrounding hospital/residential and commercial areas, thus fulfilling Shentel's desired coverage objective and company standards for reliable wireless service. Re ,ands James Boley RF Engineering Ih Lynn Koerner — 540-335-0030 Site Acquisition and Project Development Contractor, for Shentel November 21, 2017 Zoning and Subdivision Administrator 107 North Kent Suite 202 Winchester, VA 22601 Re: Shenandoah Mobile LLC — Shentel) — Site 15149 — Amherst — Conditional Use Permit Dear Sir: Shenandoah Mobile LLC (Shentel) is seeking a Conditional Use Permit under the Frederick County Zoning Ordinance for an unmanned wireless telecommunications facility. The facility will consist of a new 140' tall monopole structure with 4' lightning rod, with a 50'x 50'equipment compound within a 60'x 60' lease area. Shentel proposes to place their antenna and remote radios at a RAD center of 135'. Pursuant to the Zoning Ordinance, Shentel has designed the facility to accommodate a minimum of three (3) additional carriers. The northern side of the compound area will be surrounded by a 6' 'tall board fence with additional vegetative landscaping planting. The remainder of the compound to be secured with a chainlink fence. Access to the facility will be from a 20' access drive from 219 Round Hill Road and then to the left of the building. The access drive is an existing access that will require a minimal amount of dressing up to be an adequate access route for this facility. The telecommunications facility will have no impact on the air quality, water qualify, radiation exposure, light pollution, noise pollution, or traffic congestion. The site will be routinely maintained with a minimum of one monthly visit. The facility will have limited access and parking for a standard size vehicle and will provide adequate turn around area for fire apparatus. The Property consists of approximately 7 acres and is zoned RA, Rural Area. Adjoining properties are also zoned RA, Rural Area. Zoning and Subdivision Administrator November 21, 2017 Page 2: The Property is owned by Mr. Gregory A. Bishop, 108 Stonewall Drive and is currently used as an office for Advantage Property Management and parking of their equipment. The parcel also has a rental trailer owned by Mr. Bishop The monopole and associated compound will be sited on the northeast side portion of the Property Requirements: This Facility will be part of Shentel's telecommunications network as illustrated on the engineering plans and propagation maps included with this application. Shentel currently operates a site that is collocated on a transmission pole in the VDOT right-of- way on the south bound off ramp of Highway 37. The transmission pole and current requirements for mounting antennas does not afford us the opportunity to upgrade this site to provide the necessary services to match the surrounding network. The proposed new monopole tower will allow Shentel to add the 800 MHz spectrum and the 2500 MHz spectrum which will enhance 4G -LTE data service to residences in the surrounding area. This proposed tower will enhance the coverage at the hospital and surrounding complexes. Currently due to the high demand of high-speed data, the existing surrounding cell sites do not support the capacity needs for the area. Zoning: In accordance with the requirements of Section 165-204.19 (1)-(5), Shentel submits the following information. 1. Propagation maps depicting the need for improved service in the target area 2. The search area map 3. Shentel confirms that a complete search of the area was conducted and that no existing infrastructure is available on which to co -locate. Upon making the determination that no other structures were available in this area, Shentel then sought a rawland site to develop this proposal. 4. Radio Frequency Engineer's letter documenting compliance with Federal Communications Commission ANSI/EEE Standards. 5. The Site Agreement signed by both Shentel and Mr. Bishop addresses the information that both parties are aware of the requirements as stated in paragraph 165-204.19B(7) regarding tower removal. Section 165-204.19 of the Zoning Ordinance provides the performance standards for telecommunication uses. The proposed facility complies with the performance standards as follows: The Board of Supervisors may reduce the required setback distance for commercial telecommunications facilities as required by 165-201.038(8) of this chapter if it can be demonstrated that the location is of equal or lesser impact. When a reduced setback is requested for a distance less than the height of the tower, a certified Virginia engineer Zoning and Subdivision Administrator November 21, 2017 Page 3: shall provide verification to the Planning Commission that the tower is designed, and will be constructed, in a manner that if the tower collapses for any reason the collapsed tower will be contained in an area around the tower with a radius equal to or lesser than the setback, measured from the center line of the base of the tower. In no case shall the setback distance be reduced to less than % the distance of the tower height. Commercial telecommunications facilities affixed to existing structures shall be exempt from setback requirements, provided that they are located no closer to the adjoining property line from the existing structure. Response: Shentel is seeking a waiver of the setback requirement from the eastern and western property line. The monopole setback will be 134' from the eastern and western boundary line of the parcel (tower is 138' in height and the RA Zoning District height maximum is 35', (138'-35'=103') The normal setback is (100') in the RA Zoning District when the adjoining parcel is 6 acres or more. The normal setback of 100' plus one foot for every foot over the maximum height (35') 100' + 103' = 203'. The site plan indicates that the tower is placed 134' from the property line and the setbacks cannot be met. The resulting computation is (203'-134' = 69') resulting in a waiver request of 69'. The setback is less than the height of the proposed structure and verification from a certified engineer from Valmont Structures is provided with the application concerning this matter. (2) Monopole -type construction shall be required for new commercial telecommunications towers. The Board of Supervisors may allow lattice -type construction for new telecommunications tower when existing or planned residential areas will not be impacted and when the site is not adjacent to identified historical resources. Response: The proposed tower will be a monopole type construction (3) Advertising shall be prohibited on commercial telecommunications facilities except for signage providing ownership identification and emergency information. No more than two signs shall be permitted. Such signs shall be limited to 1.5 square feet in area and shall be posted no higher than 10 feet above grade. Response: There will be no signs or advertising on the facility other than permitted by this paragraph. (4) When lighting is required on commercial telecommunications facility towers, dual lighting shall be utilized which provides daytime white strobe lighting and nighttime red pulsating lighting unless otherwise mandated by the Federal Aviation Administration or the Federal Communications Commission. Strobe lighting shall be shielded from ground Zoning and Subdivision Administrator November 21, 2017 Page 4: view to mitigate illumination to neighboring properties. Equipment building and other accessory structures operated in conjunction with commercial telecommunications facility towers shall utilize infrared lighting and motion detector lighting to prevent continuous illumination. Response: The tower will not be lighted unless required by the FAA or as provided as a condition of approval by the Board of Supervisors. If lighting of the tower is required that lighting will be in accordance with the FAA circular and this paragraph. All other associated lighting will comply with the requirements of this paragraph. (5) Commercial telecommunications facilities shall be constructed with materials of a galvanized finish or painted a non -contrasting blue or gray unless otherwise mandated by the Federal Aviation Administration or the Federal Communications Commission. Response: The tower will be of a galvanized, gray finish (6) Commercial telecommunications facilities shall be adequately enclosed to prevent access by persons other than employees of the service provide. Appropriate landscaping and opaque screening shall be provided to ensure that equipment buildings and other accessory structures are not visible from adjoining properties, road or other rights-of-way. Response: All associated equipment at the base of the monopole structure will be within a 50'x 50' compound area surrounded by a 6' tall wood fence with a tree planting proposed around the northern side of the compound. The remainder of the fence will be chain link fence. (7) Any antenna or tower that is not operated for a continuous period of 12 months shall be considered abandoned, and the owner of such tower shall remove same within 90 days of receipt of notice from the Frederick County Department of Planning and Development. Removal includes the removal of the tower, all tower and fence footers, underground cables and support buildings. If there are two or more users of a single tower, then this provision shall not become effective until all users cease using the tower. If the tower is not removed within the ninety -day period, the County will remove the facility and a lien may be placed to recover expenses. Response: If the tower facility is not used for a continuous period of 12 months it will be removed along will all associated equipment and fencing as defined in the lease agreement with the underlying property owner. Zoning and Subdivision Administrator November 21, 2017 Page 5: Compliance with the Frederick County Comprehensive Plan: Although telecommunications facilities are not specifically addressed, Shentel feels that this proposed facility is in accordance with the design principals of the Urban Area. Many people are replacing their landline phones with wireless phones and devises. This area of the county is built up and is heavily used as an entrance to the City of Winchester and the Medical Center. Shentel seeks to improve service in this area where there is existing demand and where future growth is anticipated. This site has been sited to improve service for the residents and visitors of this portion of Frederick County and to ensure reliable coverage for emergency response personnel and those who depend upon them. Shentel is sensitive to the importance of preserving the natural and historic resources of the County. Shentel is required, as part of the Conditional Use Permit Application process to provide documentation of review pursuant to the National Environmental Policy Act (NEPA), Section 106 of the National Historic Preservation Act and the State Historic Preservation Office (SHPO). Our consultant has conducted his evaluation and the final report indicates no adverse effects of surrounding historic resources. Included in this packet also, are photo simulations of the proposed tower. These simulations were taken from various intersections and public gathering area surrounding the proposed site. Shentel submits that the proposed tower is in keeping with the core values and principals outlined for this area of Frederick County. Conclusion: We respectfully request that the conditional use permit be approved as it is in compliance with the standards of the Frederick County Zoning Ordinance, with the exception of the setback requirement from the eastern and western property lines from which we are requesting a waiver, as outlined above.

This standard has been approved by ANSI/ASCE, which has dealt with the design of antenna support structures for over 40 years. The TIA standard, based on provisions of this nationally known specification, has a long history of reliability. At its core philosophy is it's first and foremost priority to safeguard and maintain the health and welfare of the public. • The TIA standard designates a minimum wind loading for each county in the United States. Valmont uses the wind loading listed in the TIA standard unless a greater value is specified by our customer. Structures are also designed for radial ice at a code specified reduced design wind loading. Code designated coefficients are used to ensure that the structure will survive the designed wind speed. The structure can usually survive even a greater wind load than the basic design wind speed because of these conservative coefficients. • Design and loading assumptions that are used for the analyses of these structures are very conservative in nature when compared to other codes, which makes structural failure highly improbable. • Failure of a steel monopole occurs when a point is reached where the induced stresses exceed the yield strength of the material. At this point, the deflections induced in the material are no longer temporary. Hence, a permanent deflection in the monopole would exist. • The term failure above refers to local buckling at a designated point on the pole. Local buckling does not cause a free falling pole; rather it relieves the stresses from the pole at this location. Monopoles are flexible, forgiving structures, which are not generally susceptible to damage by impact loads such as wind gust or earthquake shocks. • When local buckling occurs, a relatively small portion of the shaft distorts and "kinks" the steel. When the pole begins to bend the exposure area is reduced and therefore, the force due to wind is decreased as well. Even though buckling exists, the cross section of the pole is capable of carrying the entire vertical load. Therefore, wind induced loads could not conceivably bring this type of structure to the ground due to the excellent ductile properties, design criteria, and failure mode. • Valmont's communication poles have proven to be very reliable products. Valmont has provided structures that have performed well during earthquakes in California, hurricanes in the South (including Hugo, Andrew, Opal and Katrina), and a number of tornadoes. In over 25 years of engineering and fabricating thousands of monopoles, to our knowledge Valmont has never experienced an in service failure of a communication pole due to weather induced overloading, even though, as in the cases of Hurricanes Hugo, Andrew and Katrina, the wind speeds exceeded the design wind speed. We use the latest standards, wind speed information, and sophisticated analytical tools to ensure that we maintain our unblemished record for quality.

The base material is fabricated from Grade 50 material. All plate material meets a V -Notch toughness requirement of 15 ft -lbs. @ -20 degrees Fahrenheit. By meeting the strict toughness requirement, monopoles are best suited to resist the cyclictfatigue type loading (i.e. wind induced loading) these structures exhibit. Valmont's anchor bolts are fabricated from A615 Grade 75 material. The bolts are typically 2'Y4 in diameter, made from #18J bar stock. Anchor bolts come complete with five (5) A194 Grade 2H hex nuts. For the past 40 years, our company has always guaranteed the quality of the steel used in building our structures. Material Certifications are available on all material at the time of fabrication. Fabrication of the monopole is performed in accordance with the provisions of the AISC Manual of Steel Construction and ASCE's Design of Steel Transmission Pole Structures. All welding and inspection is in accordance with the American Welding Society's Specification D1.1 -latest revision_ Testing and inspection reports are available upon request at the time of fabrication. In addition, this monopole can be designed to theoretically fail at approximately 78' AGL or above by purposely over designing the pole sections below this point. In the unlikely event the pole were to fail at this point, the significant loading reduction caused by the removal of the tower wind area and weight above would greatly reduce any chance that the remaining tower would have any structural damage, thereby providing a maximum theoretical failure radius of approximately 60' for the 138' AGL monopole. I hope these comments address any issues that you might encounter relative to the anticipated performance of monopole structures and quality of steel fabrication.
