June 15, 2017 Hand Delivered President Darryl Honda Vice President Frank Fung Commissioners Ann Lazarus, Rick Swig, and Bobbie Wilson San Francisco Board of Appeals 1650 Mission St., Ste. 304 San Francisco, CA 94103 RE: Appeal No: 17-057, Barshak vs. SFPW-BSM Subject Property: 3089 22 nd St. Description: Appeal of Permit No. 16WR-0312, issuance of a PWSFP Hearing Date: Wednesday, June 21, 2017 Dear President Honda, Vice President Fung, and Commissioners: I am writing to you in response to an appeal filed for the above-referenced Personal Wireless Service Facility Site Permit (PWSFP), which was issued to ExeNet Systems, Inc. (ExteNet) on April 14, 2017. ExteNet believes that San Francisco Department of Public Works (DPW) correctly issued the permit and respectfully requests that the Board of Appeals deny the appeal and uphold DPW s decision to issue the permit. Project Description and Background The PWSFP approval authorized ExteNet to install a small, unobtrusive wireless communications facility on a wood utility pole at the southeast corner of S. Van Ness Ave. and 22 nd St. ExteNet and its client, T-Mobile, have collaborated with the San Francisco Planning 1

Department (Planning) for several years to carefully design utility pole installations that result in little or no adverse visual impact to the surrounding community. That is an effort in both careful site selection and thoughtful design that ExteNet takes very seriously. Planning s input throughout the process has been invaluable in ensuring that ExteNet s facilities are as unobtrusive as possible and blend in with existing utility infrastructure. In this case, the selected utility pole is an ideal location because it can improve service south along S. Van Ness Ave. and east along 22 nd St. Other utility pole options mid-block in the area would likely result in the installation of two such facilities to achieve the same service improvement that the subject proposal can provide. The location is also beneficial due to its relative distance from adjacent residential uses. The nearest existing residence is approximately 20 feet away and the nearest adjacent property boundary (which property is currently vacant), is approximately 13.5 feet away. Many of the utility poles in the area are in much closer proximity to adjacent residential buildings. The proposed installation itself is one that Planning has reviewed, vetted, and approved at many locations throughout the City of San Francisco over the last several years. It includes a small antenna, concealed within a cylindrical shroud at the top of the pole, and other small ancillary components further down the pole. Please refer to the enclosed project plans and photo simulations (Exhibits A and B, respectively) to review the minimal visual impact that will result from the installation. The proposal is well-vetted, blends with the existing utility infrastructure, and will provide critical improvements to connectivity and service capacity in the area. 2

Permitting History and City Review The PWSFP application was initially submitted to and reviewed by DPW staff in December 2016. After confirming that the application was complete and complies with Public Works Code Article 25 requirements, DPW referred the project to both Planning and Department of Public Health (DPH) staff for review. DPH staff reviewed the proposal and confirmed that the proposal would be in compliance with the FCC standards and would not produce radio frequency energy exceeding the FCC public exposure limits. The DPH approval document also confirms that the installation of the equipment would be in compliance with the noise standards as outlined in the DPW Code, Article 25. Please refer to the enclosed DPH approval document dated December 23, 2016 (Exhibit C) and third-party radio frequency analysis prepared by Hammett & Edison, Inc. (Exhibit E) for more information. Because the subject utility pole is located within a RH-3 zoning district, a Zoning Protected Location, Public Works Code Article 25 and DPW Order No. 184504 require that the Planning review the application to determine whether it satisfies the Zoning Protected Location Compatibility Standard. After reviewing the application, Planning determined that a Personal Wireless Service Facility in the proposed location would be consistent with the public health, safety, convenience and general welfare and would not unreasonably affect, intrude upon or diminish any identified City resource. The Planning Department specifically determined that the proposed Personal Wireless Service Facility would not significantly detract from the character of the adjacent residential/commercial/mixed-use Districts, Scenic Vistas; or potential and/or known historic Buildings/Districts. Please see the attached Planning Department determination dated January 17, 2017 (Exhibit D). 3

After reviewing the agency responses discussed above, DPW issued a Notice of Tentative Approval, which notices were posted in the vicinity of the subject pole at S. Van Ness Ave. and 22 nd St. and were mailed to all owners and occupants with a 150-foot radius of the subject utility pole. The Tentative Approval was protested, an appointed hearing officer considered the application materials, heard testimony at a March 13, 2017 hearing, and ultimately recommended that the Tentative Approval be upheld. The DPW director agreed with the hearing officer s assessment, rejected the protest, and subsequently issued the permit. Grounds for Appeal After reviewing the Preliminary Statement of Appeal filed on April 18, 2017 and the appellant s subsequent brief filed on June 1, 2017, it appears the appellant s sole rationale for an appeal is the assertion that the proposal does not meet applicable health, safety, and environmental regulations due to radio energy emissions. As this commission is aware, federal law expressly preempts local government agencies from denying an application for a wireless communication facility on the basis of radio energy emissions so long as the applicant demonstrates compliance with the Federal Communications Commission s (FCC) standards. The federal Telecommunications Act specifically provides that No State or local government or instrumentality thereof may regulate placement, construction, and modification of personal wireless service facilities on the basis of environmental effects of radio frequency emissions to the extent that such facilities comply with the Commission s regulations concerning such emissions (U.S.C. 332(c)(7)(B)(iv)). ExteNet has demonstrated that the proposed installation will operate well within the FCC s standard for exposure to radio frequency emissions. DPH has 4

also reviewed the application materials and confirmed compliance with the City s Public Health Compliance Standard and, by extension, the FCC s emission standards. Conclusion The application for the proposed ExteNet installation at 3089 22 nd St. complies with all requirements for obtaining a PWSF, including applicable Public Works Code Article 25 and DPW Order No. 184504 regulations. Due to the lack of evidence that DPW, DPH, and/or Planning made their respective determinations in error, and ExteNet s agreement to comply with all departmental conditions of approval, there is simply no basis for overturning the PWSFP approval for ExteNet s proposed facility. We respectfully request that the Commission deny the appeal and uphold DPW s permit approval for application 16WR-0312. Sincerely, Joseph Camicia External Relations ExteNet Systems, Inc.

City and County of San Francisco Edwin Lee, Mayor DEPARTMENT OF PUBLIC HEALTH Barbara A. Garcia, MPA, Director of Health ENVIRONMENTAL HEALTH SECTION Stephanie Cushing, MSPH, CHMM, REHS, Director of EH December 23, 2016 TO: Gene Chan, Dept. of Public Works, Bureau of Street Use and Mapping FROM: Larry Kessler, Dept. Of Public Health, Environmental Health Services RE: Extenet Pole Mounted Antenna, CommScope Model 3X-V65S-GC3-3XR Location: DPW Application: Node# 3089 22 nd St 16WR-0312 72A As requested, I have reviewed the documentation that you and Extenet have provided to me regarding the proposed installation of a CommScope Model 3X-V65S-GC3-3XR, on a utility pole or similar structures located at the above listed location in the City and County of San Francisco. This review includes November 21, 2016 radio frequency energy report prepared by Hammett and Edison Inc. for this site. The report states that one CommScope Model 3X-V65S-GC3-3XR tri-directional antenna will be mounted on a utility pole near the location listed above. The antenna will be at least 45 feet above the ground level. The antenna is oriented in the 84 and 204 directions, pointing east and west along 22nd St. Due to the mounting location, the antenna would not be accessible to the general public. The maximum effective radiated power from this antenna is estimated to be 122 watts. The maximum calculated exposure level at the ground level will not exceed.00039mw/cm2, which is.039% of the FCC public exposure standard. The three dimensional perimeter of the radio frequency (RF) levels equal to the public exposure limit is calculated to extend a maximum of 4 feet from the face of the antenna and does not reach any publicly accessible areas. The maximum calculated exposure level at any nearby building is.72% of the FCC public exposure limit for the adjacent building 20 feet away. Based on the information provided in the Hammett and Edison report, I would confirm that this Extenet CommScope antenna, utility pole installation would be in compliance with the FCC standards and would not produce radio frequency energy exceeding the FCC public exposure limits. In addition, a noise evaluation was done on the combination of equipment assumed to be installed at this location which was prepared by Hammett &Edison, Inc. and was dated November 21, 2016. This evaluation found that none of the equipment being installed will produce noise. As such, the installation of the equipment would be in compliance with the noise standards as outlined in the DPW Code, Article 25. 1390 Market Street, Suite 210 San Francisco, CA 94102 Phone 252-3800, Fax 252-3894

Page 2 of 2 Approval Conditions: Ensure that any equipment associated with the pole installation of this antenna does not produce a noise in excess of 45 dba as measured at three (3) feet from the nearest residential building façade. Ensure that there are no publicly occupied areas within four (4) feet of the face of the antenna. This approval is for the antenna directions listed in the report. If an additional direction is activated a new RF report will be required. Once the antenna is installed, Extenet must take RF power density measurements with the antenna operating at full power to verify the level reported in the Hammett and Edison report and to ensure that the FCC public exposure level is not exceeded in any publicly accessible area. This measurement must be taken again at the time of the permit renewal. Extenet should be aware that the general public may have concerns about the antenna and potential RF source near their dwellings. Extenet should have in place a mechanism for taking RF power density levels in nearby dwellings when requested by the members of the general public. In accordance with the San Francisco Public Works Code, Art. 25, Sec. 1527 (a)(2)(c) Extenet is responsible for paying a fee of $210.00 to the San Francisco Department of Public Health for this review.. Please note that this approval and any conditions apply only to the equipment and installation as described. If any changes in the equipment or any increase in the effective radiated power described above are made, a new review by the Department of Public Health must be conducted.

ExteNet Systems CA, LLC Proposed DAS Node (Site No. 72A) 3089 22nd Street San Francisco, California Statement of Hammett & Edison, Inc., Consulting Engineers The firm of Hammett & Edison, Inc., Consulting Engineers, has been retained on behalf of ExteNet Systems CA, LLC, a wireless telecommunications facilities provider, to evaluate the addition of Node No. 72A to be added to the ExteNet distributed antenna system ( DAS ) in San Francisco, California, for compliance with appropriate guidelines limiting human exposure to radio frequency ( RF ) electromagnetic fields. Background The San Francisco Department of Public Health has adopted an 11-point checklist for determining compliance of proposed WTS facilities or proposed modifications to such facilities with prevailing safety standards. The acceptable limits set by the FCC for exposures of unlimited duration are: Wireless Service Frequency Band Occupational Limit Public Limit Microwave (Point-to-Point) 5 80 GHz 5.00 mw/cm 2 1.00 mw/cm 2 WiFi (and unlicensed uses) 2 6 5.00 1.00 BRS (Broadband Radio) 2,600 MHz 5.00 1.00 WCS (Wireless Communication) 2,300 5.00 1.00 AWS (Advanced Wireless) 2,100 5.00 1.00 PCS (Personal Communication) 1,950 5.00 1.00 Cellular 870 2.90 0.58 SMR (Specialized Mobile Radio) 855 2.85 0.57 700 MHz 700 2.40 0.48 [most restrictive frequency range] 30 300 1.00 0.20 Power line frequencies (60 Hz) are well below the applicable range of these standards, and there is considered to be no compounding effect from simultaneous exposure to power line and radio frequency fields. Checklist Reference has been made to information provided by ExteNet, including drawings by Cable Engineering Services, dated September 28, 2016. It should be noted that the calculation results in this Statement include several worst-case assumptions and therefore are expected to overstate actual power density levels from the proposed operations. 1. The location, identity, and total number of all operational radiating antennas installed at this site. There are reported no wireless base stations presently installed at this site, a utility pole located in the public right-of-way in front of the four-story building at 3089 22nd Street. Y3W3 Page 1 of 4

ExteNet Systems CA, LLC Proposed DAS Node (Site No. 72A) 3089 22nd Street San Francisco, California 2. List all radiating antennas located within 100 feet of the site that could contribute to the cumulative radio frequency energy at this location. While there may be other WTS facilities near this site, the additive impact at the proposed node location would be negligible in terms of compliance with the FCC public limit. 3. Provide a narrative description of the proposed work for this project. ExteNet proposes to install one antenna on the utility pole. This is consistent with the scope of work described in the drawings for transmitting elements. 4. Provide an inventory of the make and model of antennas or transmitting equipment being installed or removed. ExteNet proposes to install one CommScope Model 3X-V65S-GC3-3XR, 2-foot tall, tri-directional cylindrical antenna, with two directions activated, on top of the utility pole. The effective height of the antenna would be about 45 feet above ground, and its principal directions would be oriented toward 84 T and 204 T. 5. Describe the existing radio frequency energy environment at the nearest walking/working surface to the antennas and at ground level. This description may be based on field measurements or calculations. Because there are no antennas at the site presently, nor any direct access to the antenna location, existing RF levels for a person at the site are presumed to be well below the applicable public exposure limit. 6. Provide the maximum effective radiated power per sector for the proposed installation. The power should be reported in watts and reported both as a total and broken down by frequency band. T-Mobile proposes to operate from this facility with a maximum effective radiated power of 122 watts, representing simultaneous operation at 61 watts for AWS and 61 watts for PCS service. 7. Describe the maximum cumulative predicted radio frequency energy level for any nearby publicly accessible building or area. The maximum calculated level at any nearby building is 0.72% of the public exposure limit, at the adjacent building, located about 20 feet away. 8. Report the estimated cumulative radio frequency fields for the proposed site at ground level. For a person anywhere at ground, the maximum RF exposure level due to the proposed operation is calculated to be 0.00039 mw/cm 2, which is 0.039% of the applicable public exposure limit. Cumulative RF levels at ground level near the site are estimated to be well below the applicable public limit. Y3W3 Page 2 of 4

ExteNet Systems CA, LLC Proposed DAS Node (Site No. 72A) 3089 22nd Street San Francisco, California 9. Provide the maximum distance (in feet) the three dimensional perimeter of the radio frequency energy level equal to the public and occupational exposure limit is calculated to extend from the face of the antennas. The three-dimensional perimeters of RF levels equal to the public and occupational exposure limits are calculated to extend up to 4 feet and 1 foot out from the antenna, respectively, and to much lesser distances above and below; these do not reach any publicly accessible areas. 10. Provide a description of whether or not the public has access to the antennas. Describe any existing or proposed warning signs, barricades, barriers, rooftop striping or other safety precautions for people nearing the equipment as may be required by any applicable FCC-adopted standards. Due to its mounting location and height, the ExteNet antenna would not be accessible to unauthorized persons, and so no mitigation measures are necessary to comply with the FCC public exposure guidelines. To prevent occupational exposures in excess of the FCC guidelines, it is recommended that appropriate RF safety training be provided to all authorized personnel who have access to the antenna, including employees and contractors of the utility companies. No access within 1 foot directly in front of the antenna itself, such as might occur during certain activities, should be allowed while the base station is in operation, unless other measures can be demonstrated to ensure that occupational protection requirements are met. Posting explanatory signs * on the pole at or below the antenna, such that the signs would be readily visible from any angle of approach to persons who might need to work within that distance, would be sufficient to meet FCC-adopted guidelines. 11. Statement of authorship and qualification. The undersigned author of this statement is a qualified Professional Engineer, holding California Registration No. E-18063, which expires on June 30, 2017. This work has been carried out under his direction, and all statements are true and correct of his own knowledge except, where noted, when data has been supplied by others, which data he believes to be correct. * Signs should comply with OET-65 color, symbol, and content recommendations. Contact information should be provided (e.g., a telephone number) to arrange for access to restricted areas. The selection of language(s) is not an engineering matter; the San Francisco Department of Public Health recommends that all signs be written in English, Spanish, and Chinese. Signage may also need to comply with the requirements of California Public Utilities Commission General Order No. 95. Y3W3 Page 3 of 4

ExteNet Systems CA, LLC Proposed DAS Node (Site No. 72A) 3089 22nd Street San Francisco, California Conclusion Based on the information and analysis above, it is the undersigned s professional opinion that operation of the node proposed by ExteNet at 3089 22nd Street in San Francisco, California, will comply with the prevailing standards for limiting public exposure to radio frequency energy and, therefore, will not for this reason cause a significant impact on the environment. The highest calculated level in publicly accessible areas is much less than the prevailing standards allow for exposures of unlimited duration. This finding is consistent with measurements of actual exposure conditions taken at other operating base stations. November 21, 2016 Rajat Mathur, P.E. 707/996-5200 Y3W3 Page 4 of 4
