415.558.6377 RE: Verizon Wireless Small Cell (Microcell)

Letter of Determination for Accessory Use - Citywide

Dear Mr. Albritton:

This determination is in response to your request for a Letter of Determination (LOD) as to whether two types of small cell (microcell) wireless telecommunication services (WTS) facilities may be qualified as an

Accessory Use under the Planning Code. The small cell micro WTS facility LOD is intended to allow for

the Citywide deployment of small cell wireless technology providing voice, and data (4th Generation - Long Term Evolution, or "4G LTE)" services as part of the Verizon Wireless network.

After reviewing previous determinations, the Planning Code Section 204 (Accessory Uses, General), and

the information submitted with your letter, I have determined that the proposed microcell deployments, as described below would be incidental and subordinate to any uses within existing buildings on the subject properties and would fall within the scope of accessory uses as authorized in previous Letters of

Determination for other wireless service providers.

This authorization shall be limited to the following:

1. In areas considered Location Preferences 1 through 6, as outlined by the Wireless

Telecommunication Services (WTS) guidelines, installations may feature one of the following

configurations:

� Option 1 I Facade Mounted Micro Antenna: One or two separate antennas measuring approximately 14" high x 11" wide x 5" deep. Two coaxial cables or one 1" conduit

would connect each antenna to each of up to two remote radio equipment units (RRUs), which are each approximately 20" high x 20" wide x 8" deep. Each site would also

feature a radio cabinet measuring approximately 39" high x 26" wide x 20" deep. In

limited circumstances, such as when fiber optic backhaul connections are not available, a

backhaul antenna measuring approximately 12" high x 12" wide x 4" deep may be roof mounted, in a location not visible from off-site, in order to connect with another Verizon

Wireless facility. A radio box measuring approximately 10" high x 10" wide x 10" deep

would be mounted to the rear of the backhaul antenna.

� Option 2 I Roof Mounted Faux Vent Pipe Microcell: A single faux vent pipe measuring

up to 6 feet above roof and up to 18 inches in diameter, containing one (1) panel antenna (fitting completely within the vent pipe), or up to two (2) small cell equivalent antennas

(e.g. small cell antennas which are approximately 24" high x 16" deep/wide). Two (2)

two-inch coaxial cables or one 6" cable tray would connect each antenna to each of up to two RRUs which are each approximately 20" high x 20" wide x 8" deep. Each site would

also feature a radio cabinet measuring approximately 40" high x 26" wide x 20" deep. In

limited circumstances, such as when fiber optic backhaul connections are not available, a backhaul antenna measuring approximately 12" high x 12" wide x 4" deep may be roof

mounted, in a location not visible from off-site, in order to connect with another Verizon Wireless facility. A radio box measuring approximately 10" high x 10" wide x 10" deep

would be mounted to the rear of the backhaul antenna.

2. Individual emission calculations for each site shall be provided to the Department of Public

Health for review.

3. Based on specifications submitted with your letter, the proposed installations would not have

any adverse aesthetic or visual impacts on the subject properties or the surrounding vicinities

due to the following:

a. The antennas would not extend any more than necessary above the roofline of the subject

building.

b. Associated coaxial cable, and any associated telephone company ethernet backhaul

cabinets (as needed) shall be sufficiently screened from view.

c. Where the antennas would be screened within existing storefront elements (e.g. project signs or awnings) such elements are permitted and have been determined to be in

conformance with the Planning Code and have undergone historic preservation review

d. The installation shall be painted to match the color of the existing building, concealed, screened and/or otherwise designed to blend with the existing architectural features,

limiting them from public view.

4. Any proposed installation must comply with the design review of the Planning Department.

5. For the proposed facilities, Verizon Wireless must meet all requirements set forth within the current and subsequent versions of the Planning Department’s WTS Facility Siting Guidelines

and WTS Application Checklist for Accessory Uses.

6. This determination shall not apply to sites which: feature an existing macro/micro Verizon Wireless WTS facility (unless a removal permit has been issued), function primarily as free

standing communications towers (e.g. Sutro Tower or Bernal Heights), or to installations within

the public right-of-way (except antennas within permitted encroachments for building/storefront elements).

7. This determination does not supersede previous site-specific Verizon Wireless LODs (e.g. 45

West Portal); however, in the event a removal permit is issued, this LOD may potentially be

applied to such sites in lieu of the previous site-specific LOD.

Please be advised that if the antennas are proposed on a building of historical or architectural

significance, additional review by the Historic Preservation Commission may be required.

If for any reason the Zoning Administrator finds that this determination is no longer applicable or an

individual site merits review and authorization from the Planning Commission, the Zoning Administrator may initiate the conditional use application process.

Questions concerning this letter of determination should be directed to Omar Masry at (415)575-9116, or e-mail at omar.masrv@sfgov.org .

APPEAL: If you believe this determination represents an error in interpretation of the Planning Code or abuse in discretion by the Zoning Administrator, an appeal may be filed with the Board of Appeals within 15 days of the date of this letter. For information regarding the appeals process, please contact the

Board of Appeals located at 1650 Mission Street, Room 304, San Francisco, or call (415) 575-6880.

Re: Request for Letter of Determination for Verizon Wireless Microcell Facilities

Dear Mr. Sanchez:

We write to you on behalf of our client, Verizon Wireless, to request a letter of determination that the wireless telecommunications facilities described below ("Microcells") will be considered an "accessory use" under § 204 of the Planning Code in Location Preferences I through 6 as set forth in Section 8.1 of the Wireless Telecommunication Services (WTS) Facilities Siting Guidelines. This request is consistent with similar accessory uses authorized by letters of determination issued to other wireless service providers and Verizon Wireless.

Verizon Wireless is requesting a letter of determination in order to allow it to install small-cell technology to add capacity to its San Francisco network. The proposed Microcells will provide new 4G long-term evolution ("LTE") service. The Microcells will be installed in two basic configurations: architecturally integrated façade mounts as described in (A) below and roof-mounted false chimneys as described in (B) below. Additional radio equipment required for certain configurations is described in (C) below. A description of Verizon Wireless’s proposed Microcells is as follows:

A. Façade-Mounted Microcell. New technologies allow for a fully integrated façade-mounted radio and antenna unit. Alternately, façade-mounted antennas can be serviced by small remotely located radios as follows:

Micro Remote Radio Units (mRRU). These cabinets, which integrate both a cellular radio and antenna, measure up to 20" high x 14" wide x 7" deep. One or two cabinets are mounted on the

Scott Sanchez December 12, 2013

side of a building, painted to match the color of the existing building and concealed, screened and/or otherwise designed to blend with the existing architectural features, limiting them from public view. One architecturally-integrated three-quarter-inch diameter conduit, painted to match, connects fiber-optic cabling and power to the mRRU(s). The mRRU(s) is passively cooled and does not generate noise. A photosimulation and manufacturer’s specifications sheet’ for an mRRU are attached as Exhibit A.

2. Façade-Mounted Micro Antennas. These antennas measure up to 14" high x 12" wide x 6" deep. One or two antennas are mounted on the side of a building, painted to match the color of the existing building, and concealed, screened and/or otherwise designed to blend with the existing architectural features, limiting them from public view. A photosimulation and manufacturer’s specifications sheet for a façade-mounted micro antenna are attached as Exhibit B. Two coax cables or one architecturally-integrated three-quarter-inch diameter conduit, painted to match, connects the façade-mounted micro antenna(s) to remotely-located radio equipment (described in C, below).

B. Roof-Mounted False Vent Microcell. These antennas will be in an enclosure with measurements up to 24" high and no more than 16" in width or depth and are placed in a 17" diameter false vent limited to extend up to 5.5’ above the existing roof-line and set back at least 5.5’ from any edge of the building. From one to three false vents may be approved as accessory to one building when compatible with building architecture. A photosimulation and manufacturer’s specifications sheet for of a roof-mounted false vent microcell are attached as Exhibit C. Two 2" conduits or one 4"-6" cable tray, painted to match, connect coaxial, power and fiber cable from the roof-mounted false vent microcell to remotely-located radio equipment (described below).

C. Remotely-Located Radio Equipment.

Rooftop-Mounted Remote Radio Units. Each antenna (other than the mRRUs) will require at least one and up to two remote radio units with exterior dimensions of up to 20" high x 20" wide x 8" deep. These will be either mounted on the roof behind a façade

The manufacturer’s specification sheets attached to this letter are provided for illustrative purposes only. Actual equipment models and specifications may change but shall remain within the maximum dimensions permitted by the letter of determination. Actual equipment specifications will be included with the application for each individual microcell when required.

where available or rack-mounted anywhere on the roof within 20 feet of the antenna so as not to be visible from the street.

2. Interior or Ground-Mounted Equipment. Each installation (other than mRRUs) will require one radio cabinet with exterior dimensions of up to 40" high x 26" wide x 20" deep and one telecommunications interconnect cabinet with exterior dimensions of 27" high x 16" wide x 7" deep, all located within an existing structure, such as a telephone closet, or ground-mounted and screened from view. Photographs of a radio cabinet and telecommunications interconnect cabinet are attached as Exhibit D.

Backhaul Antenna. In limited circumstances, a backhaul antenna measuring up to 12" high x 12" wide by 4" deep may be roof-mounted to communicate with adjacent Verizon Wireless facilities. The backhaul antenna shall be set back from roof’s edge so as not to be visible from the street. A radio box measuring 10" high x 10" wide x 10" deep will be mounted to the back of the backhaul antenna. A manufacturer’s specifications sheet for a typical backhaul antenna is attached as Exhibit E.

As appropriate all components shall be painted to match the color of the existing building, concealed, screened or otherwise designed to blend with existing architectural features, limiting them from public view.

Each proposed facility shall comply with Planning Department design review. In compliance with the San Francisco Building Code, electrical and building permits shall be obtained prior to each installation.

In compliance with the San Francisco Wireless Telecommunications Facilities Siting Guidelines, each Microcell building permit application shall be accompanied by the Application Checklist for Accessory Use Applications.

Each proposed facility shall be subject to all noticing requirements under Planning Code §§ 311 and 312.

Individual emissions calculations for each Microcell will be provided to the Department of Public Health for their review. A sample such report for this type of Microcell is attached as Exhibit F to this letter for your reference.

Historically, Verizon Wireless has not used Microcells in San Francisco. However, small-cell technology will provide new 4G LTE capacity and enhanced

Verizon Wireless � Proposed Base Station (Site No. 264783 "Blossom Hill VZW Store") 690 Blossom Hill Road � San Jose, California

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. 264783

"Blossom Hill VZW Store") proposed to be located near 690 Blossom Hill Road in San Jose,

California, for compliance with appropriate guidelines limiting human exposure to radio frequency

("RF") electromagnetic fields.

Executive Summary

Verizon proposes to install a directional panel antenna on a tall utility pole located near

690 Blossom Hill Road in San Jose. The proposed operation will comply with the FCC

guidelines limiting public exposure to RF energy.

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 Freciuencv Band Occupational Limit Public Limit

Microwave (Point-to-Point) 5,000-80,000 MHz 5.00 mW/cm2 1.00 mW/cm2 BRS (Broadband Radio) 2,600 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.

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

HAMMETF & EDISON, INC. T4SQ co\SLLlING ENGINEERS

P N RV\I(O Pagel of 4

Verizon Wireless� Proposed Base Station (Site No. 264783 "Blossom Hill VZW Store") 690 Blossom Hill Road � San Jose, California

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 attached 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 construction drawings by 4Ground Design

Group, Inc., dated October 22, 2013, it is proposed to install one Ericsson Model MMRU directional

700 MHz antenna on the existing 56’/2-foot wood utility pole sited in front of the Verizon Wireless

retail store located at 690 Blossom Hill Road in San Jose. The antenna would be mounted with no

downtilt at an effective height of about 20 feet above ground and oriented toward 180’T. The

maximum effective radiated power in any direction would be 30 watts. 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 0.00082 mW/cm 2 , which is 0.17% of the applicable public exposure limit.

The maximum calculated level at the second-floor elevation of any nearby building* is 0.18% of the

public exposure limit. The maximum calculated level at the second-floor elevation of any nearby

* Located at least 30 feet away, based on photographs from Google Maps.

residence t is 0.039% 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.

Recommended Mitigation Measures

Due to its mounting location, the Verizon antenna would not be accessible to the general public, 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 utility pole,

including employees and contractors of Verizon. No access within 2V2 feet directly in front of the

antenna itself, such as might occur during maintenance work on the pole, 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 warning signsT at the antenna and/or on the pole

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.

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 near 690 Blossom Hill Road in San Jose,

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. Training of authorized personnel and posting

explanatory signs is recommended to establish compliance with occupational exposure limitations.

t Located at least 215 feet away, based on photographs from Google Maps. Warning 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. Signage may also need to comply with the requirements of PUC G095.

FCC Radio Frequency Protection Guide

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, have a significant impact on the environment. The FCC adopted the limits from Report No. 86, "Biological Effects and Exposure Criteria for Radiofrequency Electromagnetic Fields," published in 1986 by the Congressionally chartered National Council on Radiation Protection and Measurements ("NCRP"). Separate limits apply for occupational and public exposure conditions, with the latter limits generally five times more restrictive. The more recent standard, developed by the Institute of Electrical and Electronics Engineers and approved as American National Standard ANSI/IEEE C95.1-2006, "Safety Levels with Respect to Human Exposure to Radio Frequency Electromagnetic Fields, 3 kHz to 300 GHz," includes similar limits. These limits apply for continuous exposures from all sources and are intended to provide a prudent margin of safety for all persons, regardless of age, gender, size, or health.

As shown in the table and chart below, separate limits apply for occupational and public exposure conditions, 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 or thirty minutes, for occupational or public settings, respectively, do not exceed the limits, and higher levels also are allowed for exposures to small areas, such that the spatially averaged levels do not exceed the limits. However, neither of these allowances is incorporated in the conservative calculation formulas in the FCC Office of Engineering and Technology Bulletin No. 65 (August 1997) for projecting field levels. Hammett & Edison has built those formulas into a proprietary program that calculates, at each location on an arbitrary rectangular grid, the total expected power density from any number of individual radio sources. The program allows for the description of buildings and uneven terrain, if required to obtain more accurate projections.

Assessment by Calculation of Compliance with FCC Exposure Guidelines

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, have a significant 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 prudent margin of safety for all persons, regardless of age, gender, size, or health. Higher levels are allowed for short periods of time, such that total exposure levels averaged over six or thirty minutes, for occupational 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 in the 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 0.lxP

x net in mW/cm2, °BW rxD xh’

and for an aperture antenna, maximum power density Smax = 0.1 x 16 x 17 x Pnet

n x h 2 in mW/cm2 ,

where °BW = half-power beamwidth of the antenna, in degrees, and

net = net power input to the antenna, in watts, D = distance from antenna, in meters, h = aperture height of the antenna, in meters, and

11 = 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 x 1.64 x 100 x REF 2 x ERP

4 x it x D 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 a reflection coefficient of 1.6 (1.6 x 1.6 = 2.56). The factor of 1.64 is the gain of a half-wave dipole relative to an isotropic radiator. The factor of 100 in the numerator converts to the desired units of power density. This formula has been built into a proprietary program that calculates, at each location on an arbitrary rectangular grid, the total expected power density from any number of individual radiation sources. The program also allows for the description of uneven terrain in the vicinity, to obtain more accurate projections.
