Finding 23) As noted in Finding 14, the applicant has agreed to provide proof of a <br /> legal interest in the 50%fall zone (approximately 75 feet), and has committed to <br /> ensure that the area will be used for no other business than storage, which would <br /> require minimal access by employees. <br /> Finding 24) The monopole has-been designed with a theoretical failure point at <br /> approximately'75 feet from.the top of the pole. According to Marcello Posada, <br /> Associate Engineer for Summit Manufacturing, LLC, this will result in a fall zone <br /> radius of approximately 75'. Monopoles are designed in accordance with the <br /> Electronic Industries Association/Telecommunication Industries Association <br /> (EIA/TIA) specifications 222F. When properly designed according to these <br /> specifications, and when properly maintained, monopoles have a high degree of <br /> structural stability under the most extreme conditions, which serves to reduce the <br /> possibility that the tower will fall. <br /> Finding 25) Based on a study prepared by Cavanaugh Tocci Associates, Inc, the 24- <br /> hour background noise level at the south property line was 52 dB. The report states <br /> that the only noise-producing equipment associated with the project is the base <br /> transmitter station (BTS) cabinet which will be enclosed within an existing <br /> building. Cavanaugh Tocci Associates concludes that the maximum sound pressure <br /> level from the BTS cabinet will be less than 20 dBA at the nearest property line and <br /> Will not increase the background noise-level of 52 dB. Furthermore, the report <br /> concludes that the noise generated by this equipment is not expected to be audible <br /> at any location outside of the site. The nearest residential neighborhood is located <br /> approximately 850 to 900 feet away. Accordingly, the proposed facility appears to <br /> be consistent with the Commission standards relative to noise impacts. <br /> Finding 26) The'Commission ie aware and concerned about the possible cumulative <br /> health effects associated with cellular facilities. Carriers are required to file with <br /> the FCC and with the Massachusetts Department of Public Health (MDPH) to <br /> ensure that radiation emissions associated with proposed wireless communication <br /> facilities are below allowable levels. Section IX of the Technical Bulletin requires <br /> the monitoring and maintenance of a wireless communications facility after"it has <br /> been constructed. Ambient noise and RFR measurementsmust be taken prior to <br /> construction of the monopole, followed by measurements of RFR and noise levels <br /> taken 90 days after operation begins and at annual intervals thereafter. <br /> Community Character: <br /> Finding 27) Based on a crane test performed on April 23, 2002 as well as <br /> photosimulations,several locations were identified from which the tower would be " <br /> visible. Locations with minimal public views include Echo Road, Lowell Holly <br /> Reservation across MashpeetWakeby Pond, James Circle looking north across Johns " <br /> Pond, and Ashumet Road looking to the north. Areas_mrith.significant public views <br /> include Mashpee Heritage Park,Sturgis Lane intersection with Route 130, and <br /> Route 130 itself. The building that would house the equipment was not visible from <br /> any location except from the Echo Road site itself. <br /> Finding 28) The applicant proposes to house the equipment shelters within the <br /> existing building, and to enclose the leased area by a 10 foot tall chain link fence <br /> with vinyl slats that will screen the base of the proposed monopole. <br /> li <br /> Seacoast,Inc./Mashpee DRI Decision <br /> 9/19/02 <br /> Page 10 <br />
