SUMMARY
Agenda Item No. ~ Agenda Date: February 9, 2010
Application: ASA-2009-04, EXC-2009-02
Applicant: Dayna Aguirre, Sutro Consulting (for T-Mobile)
Property Owner: City of Cupertino
Property Location: 21267 Stevens Creek Boulevard (Memorial Park)
APPLICATION SUMMARY:
ARCHITECTURAL ~ SITE APPROVAL (ASA-2009-04) to allow the replacement of an
existing 60-foot tall baseball field light pole with a wireless telecommunications facility,
consisting of a base equipment enclosure and a 75-foot tall monopole that will carry six
panel antennas and the baseball field lights.
HEIGHT EXCEPTION (EXC-2009-02) to allow six panel antennas of a wireless
telecommunications facility to be mounted on a replacement pole at a height of 60-75
feet where 55 feet is allowed.
RECOMMENDATION:
Staff recommends approval of the Architectural & Site Approval and the Height
Exception per the model resolutions enclosed. Planning Commission action is final,
unless appealed to the City Council.
BACKGROUND:
The applicant, representing T-Mobile, is proposing to install a personal wireless service
facility by replacing an existing 60-foot tall baseball field light pole at Memorial Park
with a new 75-foot tall monopole that will carry six panel antennas and the baseball
field lights (Attachment 1). The pole location is just beyond centerfield between an
existing, 8-foot tall field perimeter fence and a public walkway (See photo below and
Attachment 2).
The light pole is in the north central portion of Memorial Park, which is surrounded by
the Glenbrook Apartments to the west, single family detached residences to the north,
Quinlan Community Center and a townhouse development to the east, and De Anza
College to the south. The project site is depicted by the red 4-point star in the 2006
aerial photo below.

DISCUSSION:
LocatiofzlSetback
The Cupertino Wireless Facilities Master Plan prefers personal wireless facilities to be
located in non-residential areas on taller, existing structures, such as buildings and
utility poles. The monopole would replace an existing baseball field light pole. The
base equipment enclosure is sited in an unused area between the baseball field
perimeter fence and a footpath.
The anterula setbacks from residential properties are depicted in the aerial photograph
above. They range from 276 feet to 376 feet. The City Ordinance requirement is a
minimum of 75 feet from a residential property lute.
Design/Height
Facility Design
The Wireless Master Plan Design Guidelines recommends that ~~Then an existing
structure is not suitable for antenna mounting, that any new structure approximate the
size, height, shape, colors and dimensions of the existing structure. The existing light
pole has about a 1-~-inch diameter ~n~hich tapers vertically toward the light rack.

----------------------------------------------------------------------------------
----------------------------------------------------------------------------------
The replacement pole must be stouter to support
the weight and wind load of the lights; antennas
and artwork (see discussion below). There are
also solve technical requirements, requiring
monopoles to be more rigid than city utility poles
and much less susceptible to wind sway.
The replacement pole has an approximately, 16-
inch non-tapering diameter with the light rack
mounted at the same 60-foot height. The panel
antennas will be flush-mounted to the monopole
above the light rack at a height of 63 to 75 feet.
The six panel anteruzas are organized in clusters of
three and stacked on top of each other. The panel
antei-lnas are shrouded in a radome with a 24-inch diameter. The entire monopole will
be painted to match the existing field light poles (See photosimulation, Attachment 2).
The 8-foot by 30-foot long base equipment enclosure is located to the south of the
monopole and is aligned with the baseball outfield fence. The proposed chain link
fence will be 8-feet tall, which matches the existing height of the abutting fence. It will
have a chain link security top to prevent errant baseballs from damaging the equipment
cabinets. Applicant is proposing to screen the equipment with green vinyl slats. A
condition has been added that requires a final screening plan be submitted to the City
for review and approval prior to issuance of any building permits. The screening plan
shall show alternative material upgrade to replace the proposed vinyl slats.
A rf~nTnrk
Despite the applicant's significant efforts
to camouflage the monopole as a
baseball field light, the monopole is still
in a highly visible location in a place of
community gathering. There are no
reasonable measures available to
effectively screen a 75-foot tall
monopole. The City's Wireless
Communications Facilities Ordinance
provides a design alternative to
camouflage. Municipal Code Section
19.108.070(x) (Attachment 3) allows the
City to consider "opportunities to
develop context-appropriate, artistically
enhanced aerial designs."
Dayna Aguirre (for T-Mobile) ASA-2009-04, EXC-2009-02 February 9, 2010
Page 4
In order to artistically enhance the proposed monopole, the applicant and T-Mobile
have retained the services of sculptor Riis Burwell who will craft a bronze sculpture that
can be mounted on the monopole. The sculpture depicts a leaping baseball outfielder
that will face the softball diamond. A model of the sculpture was reviewed and
recommended for approval by the Fine Arts Commission on January 24, 2010 (see later
discussion).
Height Exception
The applicant is requesting a height exception to locate the antennas at 60 to 75 feet,
where 55 feet is the maximum allowed. The existing baseball field lights are already set
at 60 feet and the antennas must be mounted above that height for three reasons:
1. Antennas mounted below the light rack interfere with the ability of maintenance
personnel to climb the pole and service the lighting.
2. Lower antenna heights may expose maintenance personnel to higher radio
frequency energy exposure since they must climb pass the antennas to reach the
lights.
3. Aesthetically, the radome will be more apparent at a lower height than above
and next to the light rack.
Please note that staff is conditioning the approval to require T-Mobile to service the
field lights on this specific pole on an ongoing basis. City staff and its contractors do
not have the experience or training to work around these types of antennas. Staff
supports the project and the height exception request because:
1. The project is consistent with the Wireless Master Plan policy that articulates the
use of existing vertical structures in non-residential areas.
2. The replacement pole approximates the existing pole and will blend in with the
existing light poles.
3. The sculpture is context-appropriate and aesthetically enhances the monopole
design. It will be an artistic asset for Cupertino.
4. The higher antenna heights are justified for the safety and aesthetic reasons
noted above.
Radio Frequency Energy (RFE) Assessment
The applicant has commissioned the preparation of a RFE report prepared by Hammett
& Edison, Consulting Engineers (Attachment 4). The report calculated the maximum
effective radiated power, the exposure distances at ground level and the distance to the
upper floors of the multiple-story buildings, which is about 276 feet. The exposure data
was evaluated against the adopted federal exposure standards.
The report concluded that the proposed facility will meet the federal safety standards
for RFE of 1.0 mW/cm2. The calculated ground level exposure is 0.061% of the
applicable public exposure limit, and at any nearby building, 0.087% of the applicable
public exposure limit.

Dayna Aguirre (for T-Mobile) ASA-2009-04, EXC-2009-02 February 9, 2010
Page 5
Since this project meets the federal safety standard for RFE, Federal
Telecommunications Law prohibits local governments from denying such a wireless
facility based on the environmental effects of its RFE generation. The attached chart
depicts the RFE exposures that are generated by various household devices and
compares it to a typical personal wireless service facility (Attachment 5).
Equipment Noise
The antennas mounted on top of the lattice are noiseless. However, the base
equipment does generate a measurable level of noise that was calculated and reported
by the applicant (Attachment 6). Sound pressure declines as distance from the source
increases. At one meter (3.28 feet) in front of the equipment cabinets, the equipment
manufacturer reports that the maximum acoustic noise level is 62 dBA. Noise
dissipates rapidly with distance from the noise source, so at the nearest residential
property, the expected equipment noise level would be 29.6 dBA. The City nighttime
noise standard at a residential property line is 50dBA. The project meets the City noise
standard.
TECHNOLOGY, INFORMATION AND COMMUNICATION COMMISSION
(TICC) COMMENTS:
Per Ordinance requirements, TICC provides technical advice to the Planning
Commission on personal wireless service facilities. TICC has designated two of its
members to review and comment on pending applications. Their comments are
summarized below:
• Calculation error noted in the noise report
• Account for nearby residential developments with respect to the RF energy
assessment
• Address potential child safety concerns at the base of the pole
• Supports height exception and design
In response to TICC comments, staff noted the minor error in the noise report. It was
confirmed the minor error does not change the conclusion of the report and that
projected noise levels will be below City noise standards. The conclusions in the RF
report were based on ground level exposure and the second floor of the closest
residential development, which is the townhouse project at Alves Drive and Anton Way. ,
All electrical equipment will be completely fenced off and secured by a chain link
enclosure. Cable connections between the enclosure and the monopole are all
underground.
FINE ARTS COMMISSION:
The Fine Arts Commission reviewed a model of the sculpture at its meeting of January
26, 2010. In attendance were the applicant, sculptor and city staff. It was confirmed
that the artwork is not subject to the General Plan public art requirement (0.25 % of the
total project budget). The Commissioners complimented the artist and praised the
1-5

Page 6
marriage of art and technology in a very utilitarian structure. They requested a few
minor changes:
• The baseball glove and the figure's head should be tilted back slightly
• The bronze should be pigmented to contrast better with the silver-grey
monopole.
• The bronze sculpture should be larger and mounted at an adequate height to
discourage vandalism. The final size (and weight) will be dictated by pole
engineering concerns
• Install an artist plaque near the base of the pole
The applicant and artist agreed to work with the Fine Arts Commission on the final size
and placement on the pole. Staff recommends that the final art piece and installation be
approved by the Director of Community Development with the consultation of the Fine
Arts Commission.
PUBLIC NOTICING:
Public hearing notices were mailed to property owners owning,land within a 1,000-foot
radius of the project property. To date, staff has not received any written or emailed
comments from neighbors.

SF15041: Memorial Park
Address: Stevens Creek Boulevard, Cupertino, CA 95014
Zone: (PR) Public Park/ Recreational
APN: 326-29-006
Project Description
T-mobile is proposing to construct, operate and maintain a wireless telecommunications facility
at the Memorial Park, located along Stevens Creek Boulevard. The proposed facility will be
designed as a seventy-five (75) foot field light standard, utilizing the same design as the existing
field lights currently installed. T-mobile is proposing to remove an existing sixty (60) foot field
light pole and replace it with a new pole placing the field lights at the same existing height.
Above the lights, a fifteen (15) foot radome will be installed, housing the antennas within. The
proposed facility will consist of three sectors of antennas, with two (2) antennas per sector,
totaling six (6) antennas. Three antennas will be vertically stacked on top of the other three,
within the fiberglass shroud (radome). The proposed radome will be painted to match the
existing field light standards within the park. The Base Transceiver Station (BTS) equipment
cabinets will be placed at the base of the pole, enclosed within an eight (8) foot in height chain
link fence with green vinyl slats as well as a chain link top (cover}.
The location and configuration of the proposed antennas have been selected to achieve the
functional requirements for T-mobile Radio Frequency Engineers. This park location has been
coordinated and acceptable by the property owner (City of Cupertino) to avoid impacting the
functionality, use and the aesthetics of the property. The development of this portion of the
network will allow its customers seamless access to a nationwide network of services, providing
an additional communication infrastructure to the community.
This location was also selected because of its position relative to existing sites, providing
favorable site geometry for federally mandated E911 location accuracy requirements and
efficient frequency reuse. Since almost 50 percent of 911 calls are from mobile phones,
effective site geometry within the overall network is needed to achieve accurate location
information of mobile users, through triangulation with active wireless facilities.
Justification
Since their introduction, wireless telecommunications systems have proven to be an invaluable
communications tool in the event of emergencies (traffic accidents, fires, etc.) and natural
disasters (earthquakes, floods, etc.) where normal land line communications are often disrupted
or inaccessible during and after an even has occurred. This service and similar technology are
utilized by numerous governmental agencies that provide emergency service. Wireless
telecommunications systems, including cellular telephones, have also proven to be invaluable
tools in business communications and everyday personal use.
Unlike other land uses, which can be spatially determined through the General Plan, the
location of wireless telecommunication facilities is based on technical requirements which
include service area, geographical elevations, alignment with surrounding sites and customer
demand components. Placement within the urban geography is dependent on these
requirements. Consequently, wireless telecommunication facilities have been located adjacent
to and within all major land use categories including residential, commercial, industrial and open
space proving to be compatible in all locations. The proposed facility will not detrimental to the
1-12

character of development, as it will be un-staffed, having no impact on circulation systems.
Furthermore, it will generate no noise, odor, smoke or any other adverse impacts to adjacent
land uses. In addition, the proposed wireless telecommunications facility will operate in full
compliance with all local, state and federal regulations including the Telecommunications Act of
1996.
T-mobile is requesting a height exception to exceed the maximum height limit of fifty-five (55)
feet for afree-standing facility. Currently, the existing sixty (60) foot field light pole already
exceeds the height limit for a wireless facility to be mounted on. In order for the lights to operate
without any shadowing and to keep maintenance personnel from close exposure, the antennas
are required to be mounted above the lights. The radome will be placed directly above the
lights affording just enough height to vertically stack the antennas within. Although the
proposed height does exceed the development standards, the approval of such request will
provide a much needed service where options are limited. Furthermore, T-mobile has worked
with the public works department to design a facility that is less obtrusive to the neighboring
community while still meeting all other development standards.
Safety and Compliance
The proposed facility will not be detrimental to the character of development, as it will be un-
staffed, having no impact on circulation systems. Furthermore, it will generate no noise, odor,
smoke or any other adverse impacts to adjacent land uses. T-Mobile technology does not
interfere with any other forms of private or public communications systems. In addition, the
proposed wireless telecommunications facility will operate in full compliance with all local, state
and federal regulations including the Telecommunications Act of 1996.
After construction of the facility, the site will be serviced once a month, during a routine
scheduled maintenance window by a service technician. The site is un-staffed and is a self-
monitored facility. There will be no impact on parking or traffic in the area as a result of
maintenance.

19.108.070 Design and Siting Review.
For aerials requiring discretionary review, the primary
review objectives are to ensure the goals of 19.108.010 are
met and to blend the design of the aerial into the surrounding
environment, or site the aerial in such a manner to minimize
the visual intrusiveness of the structure or artistically
enhance the appearance of the aerial. This review may
include, but not be limited to, the following criteria:
A. Gaps in coverage that would create emergency
communication problems;
B. Viability of alternative locations, such as
commercial, industrial, office, and public building sites.
C. Method of antenna-mounting, that is,
wall-mounting, roof-mounting or a freestanding structure.
D. Colors, materials and textures to integrate the
aerial into the surrounding environment or building;
E. Landscaping to screen the aerial;
F. Proximity and visibility of the aerial to residential
properties and public right-of-ways;
G. Dispersal of aerial locations to avoid visual
clutter;
H. Concentration of aerial locations to avoid visual
clutter;

T-Mobile • Proposed Base Station (Site No. SF15041) Attachment 4
Memorial Park on Stevens Creek Boulevard • Cupertino, California
Statement of Hammett 8~ Edison, Inc., Consulting Engineers
The firm of Hammett & Edison, Inc., Consulting Engineers, has been retained on behalf of T-Mobile,
a personal wireless telecommunications carrier, to evaluate the base station (Site No. SF15041)
proposed to be located at Memorial Park on Stevens Creek Boulevard in Cupertino, California, for
compliance with appropriate guidelines limiting human exposure to radio frequency ("RF")
electromagnetic f elds.
Prevailing Exposure Standards
The U.S. Congress requires that the Federal Communications Commission ("FCC") evaluate its
actions for possible sig~lificant impact on the environment. In Docket 93-62, effective October 15,
1997, the FCC adopted the human exposure limits for field strength and power density recommended
in 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 exposure limits. 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:
Personal Wireless Service Approx. Frequency Occupational Limit Public Limit
Broadband Radio ("BRS") 2,600 MHz 5.00 mW/cm2 1.00 mW/cm2
Advanced Wireless ("AWS") 2,100 5.00 1.00
Personal Communication ("PCS") 1,950 5.00 1.00
Cellular Telephone 870 2.90 0.58
Specialized Mobile Radio ("SMR") 855 2.85 0.57
Long Term Evolution ("LTE") 700 2.33 0.47
[most restrictive frequency range] 30-300 1.00 0.20
General Facility Requirements
Base stations typically consist of tu~o 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
about 1 inch thick. Because of the short wavelength of the frequencies assigned by the .FCC far

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. Along with the low power of
such facilities, 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 fi•om 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 T Mobile, including zoning drawings by Michael Wilk
Architecture, dated February 23, 2009, it is proposed to mount six RFS Model APXI6DWV 16DWV-
S-E-A20 directional panel antennas within a cylinder at the top of a 75-foot light pole to replace an
existing light pole sited adjacent to the baseball field located at 20833 Stevens Creek Boulevard in
Cupertino. The antennas would be mounted as stacked pairs at effective heights of about 73 and
66 feet above ground and would be oriented at about 120° spacing, to provide service in all directions.
The maximum effective radiated power in any direction would be 1,500 watts, representing the
simultaneous operation of six channels at 250 watts each. There are reported no other wireless
telecommunications base stations installed nearby.
Study Results
For a person anywhere at ground, including park users, the maximum ambient RF exposure level due
to the proposed T Mobile operation is calculated to be 0.00061 mW/cm2, which is 0.061 % of the
applicable public exposure limit. The maximum calculated power density level at the second-floor
elevation of any nearby residence* is 0.087% of the public limit. It should be noted that these results
include several "worst-case" assumptions and therefore are expected to overstate actual power density
levels.

T-Mobile • Proposed Base Station (Site No. SF15041)
Memorial Park on Stevens Creek Boulevard • Cupertino, California
Recommended Mitigation Measures
Due to their mounting location, the T-Mobile antennas are not 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, no access within 2 feet in front of the
antennas themselves, such as might occur during maintenance activities on the pole, should be allowed
while the site is in operation, unless other measures can be demonstrated to ensure that occupational
protection requirements are met. Posting explanatory warning signst on the cylinder enclosing the
antennas and/or on the pole below the cylinder, 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 infor-nation and analysis above, it is the undersigned's professional opinion that the base
station proposed by T-Mobile at Memorial Park on Stevens Creek Boulevard in Cupertino, 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. Posting of explanatory signs is recommended to
establish compliance with occupational exposure limitations.

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 ANSUIEEE C95.1-2006, "Safety

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

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 x 0.1 x Pnec ~ ~ mW/~2~
6BW .n x D x h
O.lxl6xr)xPDe~
and for an aperture antenna, maximum power density smax = ~ x h2 in mW/cm2,
where 6gW =half-power beamwidth of the antenna, in degrees, and
Pnet =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:
2.56x1.64x100xRFF2 xERP
power density s = in mW/cm2,
4x,nxD2
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.

Memorial Park on Stevens Creek Boulevard • Cupertino, California
Statement of Hammett & Edison, Inc., Consulting Engineers
The firm of Hammett & Edison, Inc., Consulting Engineers, has been retained on behalf of T Mobile,
a personal telecommunications carrier, to evaluate its base station (Site No. SF15041) proposed to be
located in Memorial Park on Stevens Creek Boulevard in Cupertino, California, for compliance with
appropriate guidelines limiting sound levels from the installation.
Prevailing Standard
The City of Cupertino sets forth limits on sound levels in Section 10.48.040 {Daytime and Nighttime
Maximum Noise Levels) of its Municipal Code, as follows for the indicated zones:
Zone Time Period Noise Limit
Residential "Day" 7 a.m. to 10 p.m. 60 dBA
"Night" 10 p.m. to 7 a.m. 50 dBA
Non-residential "Day" 7 a.m. to 10 p.m. 65 dBA
"Night" 10 p.m. to 7 a.m. 55 dBA
Figure 1 attached describes the calculation methodology used to determine applicable noise levels for
evaluation against the prevailing standard.
General Facility Requirements
Wireless telecommunications facilities ("cell sites") typically consist of two distinct parts: the
electronic base transceiver stations ("BTS" or "channels") that are connected to traditional wired
telephone lines, and the antennas that send wireless signals created by the BTS out to be received by
individual subscriber units. The BTS are often located outdoors at ground level and are connected to
the antennas by coaxial cables about 1 inch thick. The BTS typically require environmental units to
cool the electronics inside. Such cooling is often integrated into the BTS, although external air
conditioning ("AC") maybe installed, especially when the BTS are housed within a larger enclosure.
Most cell sites have back-up battery power available, to run the facility for some number of hours in
the event of a power outage. Many sites have back-up power generators installed, to run the facility
during an extended power outage.
Site 8~ Facility Description
According to information provided by T Mobile, including zoning drawings by Michael Wilk
Architecture, dated December 16, 2008, that carrier proposes to install four RBS Modei 2106 BTS,
which have integrated cooling fans, next to a light standard at the baseball field in Memorial Park,
located on Stevens Creek Boulevard near Stelling Road in Cupertino, California, as shown in Figure 2

T-Mobile • Proposed Base Station (Site No. SF15041)
Memorial Park on Stevens Creek Boulevard • Cupertino, California
Directional panel antennas are proposed to be mounted on the light standard, but this portion of the
T-Mobile base station facility does not generate acoustical energy. No stand-by power generation is
proposed for installation at this site. Other acoustical sources at or near the site are not considered as
part of this study.
Study Results
The manufacturer of the BTS reports that maximum acoustic noise levels are 62 dBA, measured at
]meter in front of the units. Based on this data, the maximum sound pressure at the nearest property
line, some 83 meters away at the corner of Alves Drive and Anton Way, is 29.6 dBA.
Compared to the City of Cupertino 50 dBA limit on noise levels applicable to this location, 29.6 dBA
represents an insignificant addition. Because dBA is a logarithmic measure, the addition actually is
less than the display resolution of typical noise meters: 50 dBA + 29.6 dBA = 50.04 dBA. That
means that the additional noise from the proposed operation, even at night when ambient conditions
are most quiet, would not be perceptible.
Conclusion
Based on the information and analysis above, it is the undersigned's professional opinion that the
T-Mobile base station proposed to be located in Memorial Park in Cupertino, California, will comply
with that city's standards limiting noise levels.

Calculation Methodology for
Derivation of Pertinent Noise Levels from Equipment
Most municipalities and other agencies specify noise limits in units of dBA, which is intended to
mimic the reduced receptivity of the human ear to Sound Pressure ("Lp") at particularly low or high
frequencies. This frequency-sensitive filter shape, shown
in the graph to the right as defined in the International
Electrotechnical Commission Standard No. 179, the
American National Standards Institute Standard No. 5.1, p
and various other standards, is also incorporated into
most calibrated field test equipment for measuring noise
levels. In analyzing situations where the frequency
composition of the emitted noise is not known, the A
filter is disregarded, and it can be seen that the results
should be conservative.

Manufacturers of many types of equipment, such as air conditioners, generators, and
telecommunications devices, often test their products in various configurations to determine the
acoustical emissions at certain distances. This data,
often presented as shown in the chart to the right,
can be used to determine the sound pressure level at
any particular distance, such as at a nearby building
or property line. The sound pressure drops as the
square of the increase in distance, according to the
formula:
LP = LK + 20 log(DK/DP),

where Lp is the sound pressure level at distance DP and LK is the known sound pressure level at
distance DK. Sound pressure levels do not add directly in units of dBA. Rather, the units need to be
converted to sound intensity in order to be added together, then converted back to dBA.
Certain equipment installations may include the placement of absorptive materials and barriers to
reduce acoustical emissions from the installation. Published in various engineering handbooks are
Noise Reduction Coefficients ("NRC") for many different materials, expressed as a unitless power
factor, with 0 being perfect reflection and 1 being perfect absorption. Unpainted concrete block, for
instance, can have an NRC as high as 0.35. However, a barrier's effectiveness, known as its Sound
Transmission Class ("STC"j, depends on the specific configuration, as well as the materials and their
surface treatment.
