DEPARTMENT OF COMMUNITY DEVELOPMENT REPORT FORM
Application: U-2004-08
Applicant (s): Sandra Steele, Sprint PCS
Property Owner: Redeemer Lutheran Church
Property Location: 940 S. Stelling Road
Agenda Date: July 12, 2004
APPLICATION SUMMARY
Use permit to locate Sprint Wireless Communication antennas and equipments within
an existing cross-tower at Redeemer Lutheran Church and to extend the height of the
cross-tower to 55 feet.
RECOMMENDA nON
Staff recommends that the Planning Commission approve the use permit in accordance
with the model resolution.
DISCUSSION
Project Description
The applicant, Sandra Steele, representing Spring PCS, has proposed to mount three
antennas to an existing church cross-tower (Exhibit A). The tower will be modified and
extended to a height of 55 feet to facilitate the antennas. The proposed Spring PCS
panel antennas will be mounted at approximately at 47' -10" high on the cross tower and
each panel will be 60 inches tall, 12 inches wide and 7 inches deep. The existing 7-foot
cross on top of the existing tower is reduced to 5 feet. The cross will retain the original
design, but will be approximately three times bigger to be in proportion to the rest of
the structure. The cross is tapered at the top and will be painted a darker brown than
the rest of the tower to stand out. The entire antenna assembly and wirings will be
completely enclosed in a cylinder, screened from public views. (See the attached
photosimulations, Exhibit B).
The proposed equipment cabinets (4 large cabinets and 2 small power/telco cabinets)
will be enclosed by a 6-foot tall wooden fence enclosure occupying an area of 15 feet by
25 feet (375 square feet). The enclosure will be located near the southeast corner of the
church property approximately 55 feet away from the easterly property line. The
proposed enclosure will not be visible from three sides (south, east, west). A noise
study was provided to demonstrate compliance with the City's noise ordinance (Exhibit
C). Noise levels were measured about five feet away from the cabinet. Further noise
attenuation will occur because of the larger setback from residences and intervening
church accessory building.

Surroundings
The site is surrounded by single-family uses to the north, east and west. Jollyman Park
is immediately south of the project. The closest residential parcel is approximately 140
feet away from the proposed antenna.
Cell Site Coverage & Site Selection
The Sprint PCS's radio frequency (RF) engineers have identified this site as an integral
site in improving Sprint's PCS network coverage to the West Valley Fwy /Hwy 85,
southern portion of De Anza College as well as in building coverage at De Anza Center
across from the site. At present, Spring PCS customers are experiencing poor service in
this area, and this site will greatly benefit the subscribers who live, work and travel in
this area. (See the attached radio coverage maps, Exhibit D.)
Conformance with the City's Wireless Facilities Master Plan
The proposed antenna project is consistent with the City's Wireless Facilities Master
Plan. In general, the plan recommends antennas to be mounted on existing tall
structures and buildings for ease of screening. A church cross-tower is ideal for
locating wireless communication antennas since the mass is already there, and in this
case it is far from residential properties. In addition, the proposed antenna panels and
wirings will be completely screened from public views as recommended in the Master
Plan.
Conformance with the City's Wireless Communications Facilities Ordinance
The current ordinance provides that transmitting aerials shall not exceed 55 feet in
height. The proposed antennas are set at 50 feet in height, with the cross at 55 feet. The
ordinance requires a residential property line setback equal to the height of the antenna
with a 50-foot minimum. The project setback is 140 feet, which far exceeds the required
setback of 50 feet.
The applicant prepared a radio frequency (RF) radiation assessment for her project to
determine if it met Federal safety standards for exposure (Exhibit E). The maximum
ground level ambient RF is calculated to be 0.0019 microwatts per square centimeter,
which is 0.19% of the applicable public exposure limit. A figure of 0.00082 microwatts
per square centimeter was calculated for the second floor level of the nearest house,
which is 0.082% of the public exposure limit. Since the applicant assumed the nearest
house was 75 feet away, and it is actually 140 feet away, the RF exposure is even less.
Other Issues
A neighborhood meeting was held on June 22, 2004 at the project site. City staff
provided the applicant with a 500-foot radius mailing list, although the applicant
misidentified it as a 300-foot radius notice. Several neighbors were present and their
<'~ - .;t
File No. U-2004-08
Page 3
July 12, 2004
concerns are summarized below, followed by staff comments. The applicant provided
several additional studies (Exhibit F) to address resident concerns. These were sent to
the meeting attendees.
Power output from the antenna unit
According to the applicant, the proposed antenna unit can potentially produce up to
1000 watts of electricity. The neighbors were concerned with the possible health risks
or safety of the antenna.
Staff comments: The maximum power iknsity of1,000 watts is fairly standard for a PCS
wireless facility. The significant number is the ambient RF exposure, which diminishes by the
square of the distance from the transmitting antenna. When this is taken into account,
immediate ground level and residential exposure is well below the Federal safety standard for RF
emissions. The RF study in Exhibit F also indicates that a collocated facility with another set of
antennas will still have RF emissions below the Federal safety standard.
Other existing Sprint PCS antenna stations
The neighbors wanted to know if the proposed antenna station is comparable to other
existing Sprint PCS's stations in the vicinity in terms of power output and RF emission.
Staff comments: According to the applicant the proposed personal wireless service facility is
similar to surrounding Sprint PCS facilities. Staff confirms that this facility is similar to other
Sprint facilities that have been approved. All other nearby sites also met the Feikral
Government's safety limit.
Alternative sites
Some neighbors questioned the possibility of locating the antenna at other sites (e.g.,
next to highway 85) instead of the proposed church property.
Staff comments: The applicant's alternatives analysis is enclosed. See Exhibit F.

Proiect Description
Project Location
The site address is 940 S. Stelling Road, Cupertino. The Assessor's Parcel Number is 359-25-
041.
Proiect Components
Antennas:
The proposal would be to mount three (3) antennas to an existing church cross-tower that would
be modified. The height of the existing church tower to the top of the cross is 40'7" and the
proposal is to increase the cross tower to a height of 55'. The proposed Sprint PCS panel
antennas, (1) per sector, (3) sectors total would be mounted at 47' 10" antenna centerline. The top
of the proposed antennas would be at 50' on the cross tower. The antenna size would be 60
inches tall by 12 inches wide by 7 inches deep (60" x 12" x 7").
The antennas would be stealthed within a proposed concealment that would serve the dual
purpose of stealthing both the antennas and the coax cable. The concealment would run from the
top of the tripod to the base of the cross. The proposed concealment would be the same diameter
as the existing structure - from leg to leg it would be 2'4" diameter in the shape of a square box.
The entire modified cross tower excluding the cross would be painted a beigelbrown color to
match the surrounding buildings.
Cross:
The existing cross is 7' and would be reduced to 5' high. The top of the cross would be at 55'.
The cross would retain the original design of being mounted on top of the tower, but would be
(3) three times as big as the original cross to make it proportionate with the rest of the structure.
The cross would be tapered at the top and painted a darker brown than the tower to stand out.
There would be a GPS antenna mounted within the equipment lease area on a cable support
ladder.
Equipment:
The equipment lease area would be located on the east side of the parcel. It would occupy
approximately 15' X 25' or a total of375 SF. It would be mounted on a concrete slab at ground
level and enclosed in a new 6'0" high wooden fence. The Mod Cell equipment includes up to
(4) large cabinets and (2) smaller power and telco cabinets. There would also be a service light.
The coax routing for the site would run underground from the equipment area to the cross tower.
From there it would run up the inside of one ofthe tripod legs and through the middle of the
antenna/coax concealment to the antennas. The coax cable would be fully stealthed.

Coveral!e Objective
Sprint PCS's radiofrequency (RF) engineers have identified this site as an integral site in
improving Sprint's PCS network coverage to the West Valley Fwy/Hwy 85, southern portion of
De Anza College as well as inbuilidng coverage at De Anza Center across from the site. It would
also facilitate coverage to the north at McClellan Rd., and the neighborhood surrounding De
Anza Blvd. At present, Sprint PCS customers are experiencing poor service in this area and this
site will greatly benefit the Sprint PCS subscribers who live, work and travel in this area.
PCS will change the future of telecommunications with easy-to-use, lightweight and highly
mobile communications devices including: portable telephones, computers and Personal Digital
Assistants (PDAs). PCS will provide voice, e-mail and internet access capabilities for customer's
communications needs virtually anywhere and at any time.
The PCS network being developed by Sprint PCS differs from typical cellular networks in that it
uses a combination of state of the art digital technology and traditional analog wireless
communications, which have been in use since the early 1980s. The benefits include call privacy
and security, improved voice quality, and an expanded menu of affordable products and services
for personal and professional communications needs. The Sprint PCS network will eventually
feature a locator device that will connect 911 calls to local police and fire departments. In the
event of an emergency, specially equipped emergency vehicles will be able to identify a
customer's location once a call is received.
Ooerational Overview
Once constructed and operational, the unmanned communications facility will provide service to
customers 24-hour per day, seven (7) days per week. Apart from initial construction activity, the
facility will be serviced on a periodic basis by a Sprint technician. It is reasonable to expect that
routine maintenance/inspection of the facility will occur once a month during nonnal working
hours. Beyond this intennittent service, Sprint requires 24-hour access to the facility to ensure
that technical support is immediately available if and when warranted. All computer equipment
needed to operate the site will be housed within the equipment cabinets.
ÓLC¡
FCC Compliance
Sprint PCS complies with the operating requirements set forth by the FCC in 47 CFR Part 15
that discusses operation in public portions of the radio spectrum. The specific public frequency
A-bands utilized by Sprint PCS are 1850 to 1865 MHz and 1930 to 1945 MHz ranges. This
section specifies technical requirements, frequencies, and radio transmitter maximum power
output such as minimum channel separation and channel bandwidth. Sprint PCS' technology
adheres to all of these requirements.
Conclusion
On behalf of Sprint PCS, the Alaris Group looks forward to working in cooperation with the City
of Cupertino to provide a wireless telecommunications facility that complies with the City's
Land Use Requirements.

Sprint PCS . Proposed Base Station (Site No. SF60xc824A)
940 South Stelling Road. Cupertino, California
Statement of Hammett & Edison, Inc., Consulting Engineers
The flnn of Hammett & Edison, Inc., Consulting Engineers, has been retained on behalf of Sprint PCS,
a wireless telecommunications carrier, to evaluate the base station (Site No. SF60xc824A) proposed to
be located at 940 South Stelling Road in Cupertino, California, for compliance with appropriate
guidelines limiting human exposure to radio ftequency ("RF") electromagnetic fields.
Prevailing Exposure Standards
The U.S. Congress requires that the Federal Communications Commission ("FCC") evaluate its actions
for possible significant 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 Radioftequency 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 Institute of Electrical and
Electronics Engineers ("IEEE") Standard C95.1-1999, "Safety Levels with Respect to Human
Exposure to Radio Frequency Electromagnetic Fields, 3 kHz to 300 GHz," includes nearly identical
exposure limits. A summary of the FCC's exposure limits is shown in Figure I. 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 thresholds for exposures of unlimited duration to radio frequency energy for
several personal wireless services are as follows:

General Facility Requirements
Base stations typically consist of two distinct parts: the electronic transceivers (also called "radios" or
"cabinets") 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 ftequencies 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. Along with the low power of
such facilities, this means that it is generally not possible for exposure conditions to approach the
maximum pennissible exposure limits without being physically very near the antennas.
Computer Modeling Method
The FCC provides direction for detennining 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 fonned at
locations very close by (the "near-field" effect) and that the power level from an energy source
decreases with the square of the distance trom 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 infonnation provided by Sprint, including zoning drawings by MSA Architecture &
Planning, Inc., dated March 8, 2004, it is proposed to mount three Andrew Model 932DG90RCE-M
directional panel antennas on the existing steel cross structure on the property of the Redeemer
Lutheran Church, located at 940 South Stelling Road in Cupertino. The structure would be increased in
height to 55 feet above ground and the antennas would be mounted at an effective height of about
48 feet above ground; they would be oriented at 1200 spacing, to provide service in all directions. The
maximum effective radiated power in any direction would be 1,000 watts. There are reported no other
wireless telecommunications base stations installed nearby.
Study Results
The maximum ambient RF level anywhere at ground due to the proposed Sprint operation is calculated
to be 0.0019 mW/cm2, which is 0.19% of the applicable public exposure limit. The maximum
calculated level on the roof of the church building is 0.36% of the public exposure limit; the maximum
calculated level at the second floor elevation of the nearest home' is 0.082% 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.
Recommended Mitigation Measures
Since they are to be mounted on a tall pole, the Sprint 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 5 feet in front of the
Sprint 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 at the antennas
and/or on the pole below the antennas, such that the signs would be readily visible ftom 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 the base
station proposed by Sprint PCS at 940 South Stelling Road in Cupertino, California, can comply with
the prevailing standards for limiting human exposure to radio ftequency energy and, therefore, need 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.

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, which are
nearly identical to the more recent Institute of Electrical and Electronics Engineers Standard

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
fonnulas in the FCC Office of Engineering and Technology Bulletin No. 65 (August 1997) for
projecting field levels. Hammett & Edison has built those fonnulas 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.

Near Field.
Prediction methods have been developed for the near field zone of panel (directional) and whip
(omnidirectional) antennas, typical at wireless telecommunications cell sites. The near field zone is
defined by the distance, D, from an antenna beyond which the manufacturer's published, far field
antenna patterns will be fully fonned; the near field may exist for increasing D until some or all of three
conditions have been met:
I) D>~
2) D> 5h
3) D> 1.6ì-.
where h = aperture height of the antenna, in meters, and
ì-. = wavelength of the transmitted signal, in meters.

The factor of 0.1 in the numerator converts to the desired units of power density. This fonnula has
been built into a proprietary program that calculates distances to FCC public and occupational limits.
Far Field.
OET-65 gives this fonnula for calculating power density in the far field of an individual RF source:
Power density S - 2.56 x 1.64 x 100 x RFF2 x ERP in mW/em2
- 4xltxD2 ' ,
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 fonnula 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.

Re:
Response to Community Meeting for Redeemer Lutheran Church held on 6/22 at
940 S. Stelling Rd. (SF60XC824-A)
Dear Colin & Gary:
At the community meeting held on 6/22 for the proposal of a new Sprint PCS wireless
telecommunications facility at the Redeemer Lutheran Church, the five (5) neighbors
raised four (4) main questions about the proposed site. These questions are outlined
below and corresponding documentation is attached that responds to their concerns.
I)
What is the power density output of the proposed site at the Redeemer Lutheran
Church and the surrounding sites? How do these levels differ at the site and then
further away within the 500' radius? (see attached Doc.#l)
2)
What alternative sites has Sprint PCS looked at in that area? Why can't they put a
site along Hwy 85? (see attached Doc.#2)
3)
What are the existing RF exposure conditions at the three (3) homes of the
attending neighbors near the proposed Sprint PCS base station? What would the
predicted difference be once the proposed site was on air? (see attached Doc.#3)
4)
What is the c~ulative effect of adding another carrier to the proposed site? (see
attached Doc.tiT - pg. 2 Section: 'Site and Facility Description & Study Results)
Please don't hesitate to contact me if you have any further questions.

To Whom It May Concern:
RE: Proposed site SF60XC824 Lutheran Redeemer Church
940 S. Stellinq Road. Cupertino CA 95014
POWER DENSITY
This report aims to address the concerns of the local residents and to answer questions raised at the
Community Meeting held on 6/22/04.
The power density for Sprint's proposed site, SF60xc824, at Lutheran Redeemer Church has been
designed with the same power densities as all of its surrounding on-air (or in-service) sites, namely
FS04XC131 (Imperial Ave, Cupertino), SF33XC591 (South De Anza Blvd @Stevens Creek Blvd),
FS04XC127 (North De Anza Blvd @Hwy85) and SF33XC413 (Bollinger Road). The average power
output for these sites 506 Watts, Effective Isotropic Radiated Power (EIRP).
In general, the power density falls off dramatically with distance from the transmitting site. This is
because it follows the Inverse Square Law, which states that for every doubling of the distance, the
power density decreases by a factor of 4 i.e. the power density is reduced by a quarter!
In considering the Redeemer Lutheran Church site, the power densities are as follows:
(ii)
At a distance of 10ft - around base of tower structure, the power density at ground level is
0.09 microwatt per square centimeter. This is 10 times less than the FCC Maximum
Permissible Exposure of 1.0 microwatt per square centimeter for the general population.
At a distance of 200ft - approximate distance of close-by residents, the power density at
ground level is 0.002microwatt per square centimeter. This is 500 times less than the FCC
Standard for the general population.
(i)
At a distance of 500 ft - the distance at which all residents must be notified in advance, in
accordance with the City Ordinance, the power density is 0.0003 microwatt per square
centimeter. This is 3000 times less than the FCC Standard for the general population.
It is important to note that these figures will be at least 100 times less, since the signal is further
weakened as it travels through the air and through obstacles such as trees, buildings, cars, etc. II is
also important to not that the FCC Standards have a safety factor of fifty (50) built into them.
(iii)
In comparison, a typical household microwave, which most people are familiar with, gives out 0.2
microwatt per square centimeter, while in use, even though the door is properly closed. This is 5
times below the FCC limit and a 100 times greater when compared with antenna output at a
distance of 200ft.
Thank you,

Re: Alternative Sites Analysis for SF60XC824A -Redeemer Lutheran Church
940 S. Stelling Rd. Cupertino CA 95014
This list of alternative sites looked at by Sprint PCS aims to address the concerns of the local
residents and to answer questions raised at the Community Meeting held on 6/22/04.
A site requires adequate RF coverage, a willing landlord, compliance with city zoning
ordinances and constructability in order for it to be a viable candidate for Sprint PCS.
The following is a list of sites that were considered prior to the selection of the Redeemer
Lutheran Church, but did NOT meet one or all of these necessary requirements:

St Jude the Apostle Church (Episcopal) - Corner of McClellan and S. Sterling was
identified, however, it has very low buildings and no adequate height. This site does
not work for RF.
New Life Church/Church of the Nazarene - 20900 McClellan Road was also
identified. It has the same cross structure as Redeemer Lutheran, but the landlord is
not interested and it is not constructible due to roof access difficulties.
Church of the Latter Day Saints - S. Stelling across from new DeAnza Parking
Structure was identified as a possible candidate, but the church has a national policy
that it will not lease to any third parties. This site has an unwilling landlord.
St. Andrew Armenian Church - on S. Stelling Road was identified as it had a tall roof
and cross, however this site is not constructible. Also, the site is too far south of the
search ring and would not cover DeAnza College area. This site was also rejected by
RF.
Jollyman Park was identified as an excellent location, however, there were no
existing vertical structures and the city zoning ordinance encourages carriers to go on
existing structures. Furthermore, it would be very difficult to bring in utilities and was
not feasible from a construction standpoint. Finally, this site is surrounded by tall
trees that would have compromised our coverage and was therefore rejected by RF.
Office Building - Corner of McClellan and S. Stelling was identified as a possible
candidate. The building is owned by DeAnza College and has a Hi-Tech training
center as a tenant, but appears vacant. The building is only about 12 feet tall and
surrounded by trees and therefore this site does not work for RF.

Monte Vista High School was identified as a candidate, however, it falls too far
outside search ring and search area and thus this site does not work for RF.
Highway 85 CalTrans at S. Stelling was also identified as a possible candidate, but
there are no existing tall structures at the site and no utilities. There is a sound wall on
one side of overpass and a 50' to 60' pole would cover both the freeway and
residential areas, but would be very close to and very visible from residential
properties on Orogrande Place and Festival Drive and would not meet the aesthetics
of the city zoning. Finally, the area is south of the search area, and would not cover
De Anza adequately. Therefore, this site was also rejected by RF,
Highway 85 CalTrans at McClellan was identified as a possible candidate, but
Caltrans recently rejected a Metro PCS proposal for this Caltrans yard due to
maintenance and security concerns. Therefore this site was rejected as it has an
unwilling landlord. Also, this site is located in the very north part of search area and
would not cover the residential areas to the south. There are no existing tall structures
in the area, There is only one 35' telephone pole that could not be used because it is
not tall enough to cover the area, Therefore, this site was rejected by RF.
DeAnza College was identified as a candidate. This site has a new parking structure
and other buildings that are all too far to the north of the search ring. We need
additional coverage at De Anza, but not a site directly on the campus, Therefore this
site does not work for RF.

Dear Sandra:
As you requested, we conducted measurements ofthe existing RF exposure conditions at three
homes near the location of the proposed Sprint PCS base station (Site No. SF60xc824A) on the
property of the Redeemer Lutheran Church, at 940 South Stelling Road in Cupertino. The
measurement equipment used was a Wandel & Goltermann Type EMR-300 Radiation Meter
with Type 8 Isotropic Electric Field Probe (Serial No. P-0036). Both meter and probe were
under current calibration by the manufacturer. The maximum power density levels observed at
the homes on June 22, 2004, about 8:30 PM, not including the contributions of other RF
sources, such as TV, monitor, and microwave, were all so low as to be below the minimum
measurement range of the instrument, i.e., less then 0.13% of the most restrictive public limit.
These homes were located at the following addresses:
771 Huntridge Lane
903 South Stelling Road
7655 Dumas Drive
Based on the information provided by Sprint, it is proposed to mount three Andrew Model
932DG90RCE-M directional panel antennas on the existing steel cross structure to be modified
to a height of 55 feet. The Sprint antennas will be mounted at an effective height of about 48
feet above ground, and Sprint reports that it will initially operate at a maximum effective
radiated power ("ERP") of 500 watts, with a maximum eventual build-out ERP of 1,000 watts.
The maximum ambient RF level anywhere at ground due to the proposed Sprint initial and
maximum operations is calculated to be 0.095% and 0.19% of the applicable public exposure
limit, respectively. The power density levels observed at the three homes are not expected to
change significantly after the Sprint station is operational.

Sprint PCS . Proposed Base Station (Site No. SF60xc824A)
940 South Stelling Road. Cupertino, California
Statement of Hammett & Edison, Inc., Consulting Engineers
The firm of Hammett & Edison, Inc., Consulting Engineers, has been retained on behalf of Sprint
PCS, a wireless telecommunications carrier, to evaluate the base station (Site No. SF60xc824A)
proposed to be located at 940 South Stelling Road in Cupertino, California, for compliance with
appropriate guidelines limiting human exposure to radio frequency ("RF") electromagnetic fields.
Prevailing Exposure Standards
The U.S. Congress requires that the Federal Communications Commission ("FCC") evaluate its
actions for possible significant 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 Institute of Electrical and
Electronics Engineers ("IEEE") Standard C95.1-1999, "Safety Levels with Respect to Human
Exposure to Radio Frequency Electromagnetic Fields, 3 kHz to 300 GHz," includes nearly identical
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 thresholds for exposures of unlimited duration to radio frequency energy for
several personal wireless services are as follows:
Personal Wireless Service
Personal Communication ("PCS")
Cellular Telephone
Specialized Mobile Radio

General Facility Requirements
Base stations typically consist of two distinct parts: the electronic transceivers (also called "radios" or
"cabinets") 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 I inch thick. 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. Along with the low power of
such facilities, this means that it is generally not possible for exposure conditions to approach the
maximum pennissible 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 fonned at
locations very close by (the "near-field" effect) and that 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 Sprint, including zoning drawings by MSA Architecture &
Planning, Inc., dated March 8, 2004, it is proposed to mount three Andrew Model 932DG90RCE-M
directional panel antennas on the existing steel cross structure on the property of the Redeemer
Lutheran Church, located at 940 South Stelling Road in Cupertino. The structure would be increased
in height to 55 feet above ground and the antennas would be mounted at an effective height of about
48 feet above ground; they would be oriented at 120° spacing, to provide service in all directions. The
maximum effective radiated power in any direction would be 1,000 watts. Similar antennas for use by
another wireless telecommunications carrier could be mounted lower on the same structure. For the
purposes of this study, it is assumed that another PCS carrier were also to install an identical operation,
at an effective height of about 40 feet above ground.
Study Results
The maximum ambient RF level anywhere at ground due to the proposed Sprint operation by itself is
calculated to be 0.0019 mW/cm2, which is 0.19% of the applicable public exposure limit; the
maximum calculated cumulative level at ground for the simultaneous operation of both PCS carriers is
calculated to be 0.39% of the public exposure limit. The maximum calculated cumulative level on the
roof of the church building is 1.6% of the public exposure limit; the maximum calculated cumulative
level at the second floor elevation of the nearest home' is 0.20% 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. The cumulative results are based upon a hypothetical build-

out of a second PCS carrier at the proposed site in order to demonstrate that such utilization of the
facility can be made in conformance with FCC guidelines for exposure to radio frequency radiation.
Although the results are believed to be conservative, they should not be used to represent actual
exposure conditions at the site after construction of both carriers. When the second carrier's facilities
have been specified, a complete calculation study should be performed.
Recommended Mitigation Measures
Since they are to be mounted on a tall pole, the 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 5 feet in front of the
Sprint 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 explana~ory warning signs! at the antennas
and/or on the pole below the antennas, 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 the base
station proposed by Sprint PCS at 940 South Stelling Road in Cupertino, California, can comply with
the prevailing standards for limiting human exposure to radio frequency energy and, therefore, need
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.
! Warning signs should comply with ANSI C95.2 color, symbol, and content conventions. In addition, 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.

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, which are
nearly identical to the more recent Institute of Electrical and Electronics Engineers Standard

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.

RFR.CALC TM Calculation Methodology
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 cell sites. The near field zone is
defined by the distance, D, from an antenna beyond which the manufacturer's published, far field
antenna patterns will be fully formed; the near field may exist for increasing D until some or all of three
conditions have been met:
I) D>~
2) D> 5h
3) D> 1.6ì..
where h = aperture height of the antenna, in meters, and
ì.. = wavelength of the transmitted signal, in meters.
The FCC Office of Engineering and Technology Bulletin No. 65 (August 1997) gives this formula for
calculating power density in the near field zone about an individual RF source:
. S 180 0.1 x Poet 2
power density ~!JEw x It X D x h' inmW/cm,
where BBW = half-power beamwidth of antenna, in degrees, and
Poet = net power input to the antenna, in watts.
The factor of 0.1 in the numerator converts to the desired units of power density. This formula has
been built into a proprietary program that calculates distances to FCC public and occupational limits.
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 RFF2 x ERP, in mW/cm2,
4xltxD2
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.

Ref.: Use Permit to operate a separate bar at 19780 Stevens Creek Boulevard.
Dear Planning Commission:
We are strongly objecting to a bar that will be dispensing alcoholic beverages so close to
a quiet residential neighborhood in which we live,
This bar would be located right next to Longs drugstore and other stores that are visited
by many families with small children, which could be exposed to intoxicated persons.
Please deny this Use Permit.
Sincerely,
-H~ f~~
