Statement of Hammett & Edison, Inc., Consulting Engineers

The firm of Hammett & Edison, Inc., Consulting Engineers, has been retained on behalf of Verizon Wireless, a personal wireless telecommunications carrier, to evaluate the base station (Site No. 291115 “North Berkeley”) proposed to be located at 1615 Martin Luther King, Jr. Way in Berkeley, California, for compliance with appropriate guidelines limiting human exposure to radio frequency (“RF”) electromagnetic fields.

Executive Summary

Verizon proposes to install directional panel antennas above the roof of the residential building located at 1615 Martin Luther King, Jr. Way in Berkeley. The proposed operation will comply with the FCC guidelines limiting public exposure to RF energy; certain mitigation measures are recommended to comply with FCC occupational guidelines.

Prevailing Exposure Standards

The U.S. Congress requires that the Federal Communications Commission (“FCC”) evaluate its actions for possible significant impact on the environment. A summary of the FCC’s exposure limits is shown in Figure 1. These limits apply for continuous exposures and are intended to provide a prudent margin of safety for all persons, regardless of age, gender, size, or health. The most restrictive FCC limit for exposures of unlimited duration to radio frequency energy for several personal wireless services are as follows:

Wireless Service Frequency Band Occupational Limit Public Limit Microwave (Point-to-Point) 5–80 GHz 5.00 mW/cm2 1.00 mW/cm2 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

General Facility Requirements

Base stations typically consist of two distinct parts: the electronic transceivers (also called “radios” or “channels”) that are connected to the traditional wired telephone lines, and the passive antennas that send the wireless signals created by the radios out to be received by individual subscriber units. The transceivers are often located at ground level and are connected to the antennas by coaxial cables.

A small antenna for reception of GPS signals is also required, mounted with a clear view of the sky. Because of the short wavelength of the frequencies assigned by the FCC for wireless services, the antennas require line-of-sight paths for their signals to propagate well and so are installed at some height above ground. The antennas are designed to concentrate their energy toward the horizon, with very little energy wasted toward the sky or the ground. This means that it is generally not possible for exposure conditions to approach the maximum permissible exposure limits without being physically very near the antennas.

Computer Modeling Method

The FCC provides direction for determining compliance in its Office of Engineering and Technology Bulletin No. 65, “Evaluating Compliance with FCC-Specified Guidelines for Human Exposure to Radio Frequency Radiation,” dated August 1997. Figure 2 describes the calculation methodologies, reflecting the facts that a directional antenna’s radiation pattern is not fully formed at locations very close by (the “near-field” effect) and that at greater distances the power level from an energy source decreases with the square of the distance from it (the “inverse square law”). The conservative nature of this method for evaluating exposure conditions has been verified by numerous field tests.

Site and Facility Description

Based upon information provided by Verizon, including zoning drawings by MST Architects, Inc., dated September 1, 2015, it is proposed to install eight Andrew Model SBNHH-1D45C directional panel antennas inside a new view screen enclosure to be installed above the roof of the four-story residential building located at 1615 Martin Luther King, Jr. Way in Berkeley. The antennas would employ no downtilt, would be mounted at an effective height of about 45 feet above ground, about 6 feet above the roof, and would be oriented in pairs toward 80°T, 175°T, 260°T, and 355°T. The maximum effective radiated power in any direction would be 16,270 watts, representing simultaneous operation at 6,750 watts for AWS, 6,440 watts for PCS, and 3,080 watts for 700 MHz service; no operation on cellular frequencies is presently proposed from this site. There are reported no other wireless telecommunications base stations at the site or nearby.

Study Results

For a person anywhere at ground, the maximum RF exposure level due to the proposed Verizon operation is calculated to be 0.024 mW/cm2, which is 2.6% of the applicable public exposure limit. The maximum calculated level for a person on any of the patio areas above the third floor of the building is 0.20 mW/cm2, which is 23% of the public exposure limit. The maximum calculated level for a person anywhere inside the top-floor penthouse unit is 0.054 mW/cm2, which is 6.8% of the public limit; the maximum calculated level for a person on the third floor of the building is

Verizon Wireless • Proposed Base Station (Site No. 291115 “North Berkeley”) 1615 Martin Luther King, Jr. Way • Berkeley, California

V1CX.1 Page 3 of 4

0.0086 mW/cm2, which is 0.94% of the public limit. The maximum calculated level at the top floor elevation of any other nearby residence is 0.063 mW/cm2, which is 7.1% of the public exposure limit. It should be noted that these results include several “worst-case” assumptions and therefore are expected to overstate actual power density levels from the proposed operation. Levels are calculated to exceed the applicable public exposure limit on the roof of the subject building, in front of the antennas.

Site Safety Plan

UNCONTROLLED PUBLIC ENVIRONMENT – Due to their mounting location and height, the Verizon antennas would not be accessible to unauthorized persons, and so no mitigation measures are necessary to comply with the FCC public exposure guidelines.

CONTROLLED OCCUPATIONAL ENVIRONMENT – To prevent occupational exposures in excess of the FCC guidelines, it is recommended that appropriate RF safety training, to include review of personal monitor use and lockout/tagout procedures, be provided to all authorized personnel who have access to elevated areas above the roof, including employees and contractors of Verizon and of the property owner. No access within 13 feet directly in front of the antennas themselves, such as might occur during certain maintenance 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. It is recommended that boundary lines be marked on the roof with blue and yellow paint to identify areas that are calculated to exceed the public and occupational FCC limits, respectively, as shown in Figure 3. It is recommended that explanatory signs* be posted at the roof access door, at the boundary lines, and on the screens in front of the antennas, readily visible from any angle of approach to persons who might need to work within that distance. †

Conclusion

Based on the information and analysis above, it is the undersigned’s professional opinion that operation of the base station proposed by Verizon Wireless at 1615 Martin Luther King, Jr. Way in Berkeley, 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 * 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, and guidance from the landlord, local zoning or health authority, or appropriate professionals may be required.

The U.S. Congress required (1996 Telecom Act) the Federal Communications Commission (“FCC”)to adopt a nationwide human exposure standard to ensure that its licensees do not, cumulatively, havea significant impact on the environment. The FCC adopted the limits from Report No. 86, “BiologicalEffects and Exposure Criteria for Radiofrequency Electromagnetic Fields,” published in 1986 by theCongressionally chartered National Council on Radiation Protection and Measurements (“NCRP”).Separate limits apply for occupational and public exposure conditions, with the latter limits generallyfive times more restrictive. The more recent standard, developed by the Institute of Electrical andElectronics Engineers and approved as American National Standard ANSI/IEEE C95.1-2006, “SafetyLevels with Respect to Human Exposure to Radio Frequency Electromagnetic Fields, 3 kHz to300 GHz,” includes similar limits. These limits apply for continuous exposures from all sources andare intended to provide a prudent margin of safety for all persons, regardless of age, gender, size, orhealth.

As shown in the table and chart below, separate limits apply for occupational and public exposureconditions, with the latter limits (in italics and/or dashed) up to five times more restrictive:

Higher levels are allowed for short periods of time, such that total exposure levels averaged over six orthirty minutes, for occupational or public settings, respectively, do not exceed the limits, and higherlevels also are allowed for exposures to small areas, such that the spatially averaged levels do notexceed the limits. However, neither of these allowances is incorporated in the conservative calculationformulas in the FCC Office of Engineering and Technology Bulletin No. 65 (August 1997) forprojecting field levels. Hammett & Edison has built those formulas into a proprietary program thatcalculates, at each location on an arbitrary rectangular grid, the total expected power density from anynumber of individual radio sources. The program allows for the description of buildings and uneventerrain, if required to obtain more accurate projections.

MethodologyFigure 2

The U.S. Congress required (1996 Telecom Act) the Federal Communications Commission (“FCC”) toadopt a nationwide human exposure standard to ensure that its licensees do not, cumulatively, have asignificant impact on the environment. The maximum permissible exposure limits adopted by the FCC(see Figure 1) apply for continuous exposures from all sources and are intended to provide a prudentmargin of safety for all persons, regardless of age, gender, size, or health. Higher levels are allowed forshort periods of time, such that total exposure levels averaged over six or thirty minutes, foroccupational or public settings, respectively, do not exceed the limits.

Near Field. Prediction methods have been developed for the near field zone of panel (directional) and whip(omnidirectional) antennas, typical at wireless telecommunications base stations, as well as dish(aperture) antennas, typically used for microwave links. The antenna patterns are not fully formed inthe near field at these antennas, and the FCC Office of Engineering and Technology Bulletin No. 65(August 1997) gives suitable formulas for calculating power density within such zones.

For a panel or whip antenna, power density S = 180��BW

�0.1� Pnet� �D2 � h

, in mW/cm2,

and for an aperture antenna, maximum power density Smax = 0.1 � 16 � � � Pnet

� � h2 , in mW/cm2,

where �BW = half-power beamwidth of the antenna, in degrees, andPnet = net power input to the antenna, in watts,

D = distance from antenna, in meters,h = aperture height of the antenna, in meters, and� = aperture efficiency (unitless, typically 0.5-0.8).

The factor of 0.1 in the numerators converts to the desired units of power density.

Far Field. OET-65 gives this formula for calculating power density in the far field of an individual RF source:

power density S = 2.56 �1.64 �100 � RFF2 � ERP

4 �� �D2 , in mW/cm2,

where ERP = total ERP (all polarizations), in kilowatts,RFF = relative field factor at the direction to the actual point of calculation, and

D = distance from the center of radiation to the point of calculation, in meters.

The factor of 2.56 accounts for the increase in power density due to ground reflection, assuming areflection coefficient of 1.6 (1.6 x 1.6 = 2.56). The factor of 1.64 is the gain of a half-wave dipolerelative to an isotropic radiator. The factor of 100 in the numerator converts to the desired units ofpower density. This formula has been built into a proprietary program that calculates, at each locationon an arbitrary rectangular grid, the total expected power density from any number of individualradiation sources. The program also allows for the description of uneven terrain in the vicinity, toobtain more accurate projections.

Dear Kim:

As you requested, we have performed additional calculations of RF exposure levels at the proposed site for a new Verizon Wireless base station (Site No. 291115 “North Berkeley”) at 1615 Martin Luther King Jr. Way in Berkeley, California.

Our RF exposure study, dated April 15, 2016, had reported maximum calculated levels for a person inside the penthouse apartment to be 6.8% of the FCC public limit and at ground to be 2.6% of the limit. The calculated levels at the specific locations requested are, as expected, less than these maximums already reported:

Calculated Exposure Level Location % FCC Public Limit front (west) side of penthouse apartment 1.5% rear (east) side of penthouse apartment 5.6% side (north) of penthouse apartment 6.0% side (south) of penthouse apartment 1.4%

rear property line abutting 1608 Bonita Avenue 0.72%

Please let us know if we can be of further assistance.

Sincerely yours, William F. Hammett, P.E.
