Project Proposal Summary
T-Mobile's wireless network currently has a large coverage gap serving the residential Kennydale area within the
city of Renton. This area is located northeast of the intersection of 1-405 and Highway 900 and southwest of the
border of Newcastle. Currently T-Mobile serves much of this area of Kennydale through commercially zoned
sites along the freeway system: two sites along the 1-405 corridor and two additional sites along Highway 900.
Due to the dense nature of the residential zoning in the area, there are no existing commercial or industrial
zoned parcels available to adequately affect coverage in the subject area. Currently, T-Mobile is not able to
provide adequate phone, data, and E-911 services to the subject area.
In the 2008 Utilities Supplement to the Renton Comprehensive Plan, the city recognizes the changing structure
and importance of a complete cellular network. The section notes, "As cell sites were initially developed, a few
large cells were established using hilltops or tall buildings to site transmission and receiving antennas. This
allowed for maximum coverage of the large cell. Clusters of smaller cells have since replaced the larger
configuration ... Thus, shorter antennas and poles provide coverage for the smaller cell sites. This division of cells
will continue to occur as the demand for cellular service grows." T-Mobile's proposal is representative of this
recognized need.
T-Mobile proposes a new wireless communications facility at the location of 2424 NE 27th Street. The site is
zoned Residential-8 (R-8). It consists of 1.99 acres in size and currently houses a 3,552 square foot social hall
maintained by the Living Memorial Association of Kennydale. The WCF would be located at the northern side of
the existing building on site. There is a ravine on the NE section of the parcel that runs from the NW to the SE.
The presence of the ravine does not affect planned proposal as the site is positioned directly adjacent to the
existing building within its building shadow. Proposed site can be accessed from either the SW or SE access point
on the parcel. There is ample parking space within the existing parking lot, adjacent to the site to the north, or
adjacent to the building on the west.
The proposed WCF will be used for the transmission and reception of radio frequency signals for cell phone
coverage in the surrounding residential area of Kennydale. It is comprised of a 59'11" flush mount monopole, as
well as 4 associated radio cabinets positioned on a 10'x15' pad at the base of the tower. WCF would comprise a
total area of ll'x22', wholly enclosed by a chain link fence with tan privacy slats for maximum screening. No
landscaping is proposed due to the fact that it would hinder use of the parking lot and limit access across the
eastern portion of the lot.
Proposed WCF would contain maximum screening requirements allowed under the existing technology. No
existing trees will be affected or moved by the proposed construction of the WCF. Furthermore, the monopole is
proposed to be less than 60' in height, well below the existing tree line on the property. The site is also highly
shielded by existing trees to the west and east of the proposed area. The monopole itself is proposed to have
flush mount antennas painted to match the green color of the tower. The ground equipment is enclosed and
positioned behind an existing building, providing additional screening to the structure.

Per Section Hof the Preliminary Report to the Hearing Examiner, Department of Community and Economic
Development staff recommended the following conditions. T-Mobile responses are included below immediately
following each recommendation.
1. The applicant shall submit a copy of the Notice of Proposed Construction a minimum of 30 days prior to the
issuance of any building permit for any wireless communication support structure or attached WCF.
Response: T-Mobile will comply with this request as further described in RMC 4-4-030.
2. The applicant shall submit a lighting plan to Planning Division Project Manager for review and approval prior
to building permit submittal, if the FAA requires the tower to be lit.
Response: T-Mobile has acquired FAA approval for the proposed location. The proposal was determined not to
be a hazard to air navigation. Furthermore, the FAA noted that marking and lighting were not necessary for
aviation safety.
3. The applicant shall move the location of the WCF further north by at least 70 feet from the proposed location.
The revised location shall be submitted by the applicant to the Planning Division Project manager (see Exhibit
14) prior to building permit submittal for approval.
Response: T-Mobile has taken great care in selecting the proposed location for the wireless facility. This
includes examining such factors as setback compliance, distance from topography change, visual effect,
property use, and efficacy of cellular coverage. In this case, our coverage would be significantly affected if the
site were relocated to the northern section of the parcel. Specifically, the presence of the trees so close to the
tower location would greatly hinder coverage to the North, South, and Southwest. The only way that coverage
could be adequately provided from such location would be at an altered height of at least 80'.
4. The applicant shall install either a six-foot high CMU block wall or a six foot high solid cedar wood fence
around the accessory equipment cabinets prior to issuance of a building permit. The applicant shall submit
design elevations for approval by the Planning Division Project Manager prior to submittal of building permit.
Response: T-Mobile would be willing ta adopt a solid cedar wood fence design in order ta further enhance the
aesthetics of the site design.
5. The applicant shall provide a revised landscape plan detailing a five-foot landscape strip drought tolerant
shrubs (such as Arbor Vitae) surrounding the perimeter WCF enclosure to reduce visual impact from the
residential properties to the west. This landscape plan shall be submitted prior to the issuance of the building
permit. The proposed landscaping shall be installed and inspected prior to building permit issuance.
Response: T-Mobile believes that the current design and proposed design change to cedar fence offers
adequate visual screening of ground equipment. The proposed location behind the building significantly limits
visibility from the street. Adding landscaping would only limit use of the property. The landlord has confirmed
this assertion in a letter dated 1/18/09 and submitted to the City of Renton.

Radio Frequency Engineer Site Analysis
T-Mobile Project No.: SE04810A
Project Name: Edmonds Ave NE
Project Description: Install 3 panel antennas on a steel pole with antenna tip height of
59'-11"
Location: 2424 NE 27th St, Renton
Date: January 15, 2009
T-Mobile Site Selection Overview
Wireless systems are expanded or introduced in a given area to improve service to customers.
There are typically three reasons to add a new facility: extending the coverage to new areas,
increasing the capacity of the system within the current service area, or improving quality. Some
sites do all three.
Coverage:
Coverage can be defined as having a certain level of signal strength in a particular area.
T-Mobile's target is to provide -76dBm of signal strength to our customers in all areas.
This level of coverage guarantees reliable signal strength inside buildings to provide
excellent voice quality in residential neighborhoods and commercial areas. In today's
competitive marketplace, T-Mobile requires adequate coverage to be competitive and to
fulfill our responsibilities under our FCC license.
Existing and proposed coverage is demonstrated by use of propagation maps and drive
test data. The propagation maps are computer simulations of wireless signal coverage
in a given area. One map shows the predicted coverage as it exists without the
proposed facility. The other map shows predicted coverage with the proposed facility in
place. Drive test data consists of actual wireless signal strength documented in the field
by driving through the coverage objective with measurement equipment. The existing
signal strength is measured by driving through the proposed coverage area and
recording call strength throughout the route driven. Next, a temporary antenna is lifted
to the proposed facility height and the same area is driven again while signal strength is
recorded. The data collected is plotted on maps showing coverage throughout the
proposed area.
Capacity:
Capacity is the number of calls that can be handled by a particular antenna site. When
we make phone calls, our mobile phones communicate with a nearby antenna site that
then connects to land based phone lines. Ongoing phone calls occupy the resources of
the serving site, which can handle only a limited number of calls. When a particular
antenna site is handling a sufficient number of calls the available RF channels assigned
to that site are used up. When this occurs, the wireless phone user will hear a busy
signal on his or her phone. The call traffic of antenna sites is continuously monitored
and analyzed so that overloading of sites is prevented. Careful projection allows
sufficient lead time to design, permit, and construct the wireless facility prior to
exceeding the capacity of surrounding sites. Capacity cell sites are typically required in
areas that currently have sufficient coverage. The objective for a capacity site is to
handle call increased volume rather than increase a coverage area.
Interference:
In areas with good coverage, phone calls may still have poor quality that the caller hears
as warbled voices or temporary loss of communication. This is often caused by
interference. Wireless telephone systems reuse specific radio frequencies at different
cell antenna locations. When frequencies are reused at nearby sites, interference may
result. Engineers work to achieve the most efficient use of limited frequency resources
and reduce interference.
Unfortunately, there are still areas where interference is nearly unavoidable. This
typically occurs in areas where one antenna site is having trouble handing off calls to
another. On a freeway or busy roadway, for example, the network juggles a call
between competing antenna sites seeking to find the best one. When this occurs, the
solution is often to locate a new antenna site as close to the location where the bad
handoff is occurring. Interference is documented by measuring received call quality (Rx
Qual) during a drive test similar to that performed to measure coverage. Rx Qual is a
measurement of digital data (voice signal) lost as the result of poor communication
between adjacent cell sites. Drive test maps demonstrate the Rx Qual of the area as it
exists both with and without the proposed cell site.
Site Selection Process for this Location
This installation is proposed to enhance road coverage and indoor coverage along the
residential and commercial area of Edmonds Ave near Highlands Park and Sunset Court Park.
This determination was a result of a combination of customer complaints and service requests,
and preliminary design analysis as illustrated at Attachments 1A and 1 B. Terrain data within the
service area is entered into a computer modeling program along with a series of variables, such
as proposed antenna height, available radio frequencies and wireless equipment
characteristics. From this information T-Mobile's RF engineers determined an area for the
optimum location and height of the Wireless Communication Facility (WCF) antenna to
maximize the coverage objective.
To provide coverage in this area, it is necessary to locate a facility Edmonds Ave. The specific
location of the proposed site has been selected to maximize coverage while minimizing the
antenna height requirement. Significant deviation from this location will result in reduced
effectiveness, including possible invalidation of the site candidate altogether. The required
antenna height is the minimum acceptable to provide the needed coverage with respect to that
from neighboring cell sites. Lower antenna height will result in reduced effectiveness, again
including possible invalidation of the candidate. In some cases, an increased antenna height is
possible which can allow some greater flexibility in location placement. However, too much
RF Documentation for SE04810A Edmonds Ave
Page 2 of7
antenna height is unacceptable as it creates interference conditions that degrade performance
of one or more other existing cell sites in the T-Mobile network.
When this technical analysis was completed, a search area map and other requirements were
provided to T-Mobile's real estate and zoning specialists. With this information in hand, T-Mobile
ranked potential sites. Whenever feasible, T-Mobile strives to acquire property that is properly
zoned and adjacent to compatible land uses. T-Mobile attempts to select a location that
minimizes or limits any negative visual impacts on adjacent or nearby residential areas to the
greatest extent possible. Sites adjacent to existing tall power lines, antenna facilities, water
treatment facilities, and on the tops of buildings are selected when they meet the other technical
requirements of the system. New, freestanding towers are avoided as are locations adjacent to
view corridors or where demolition is required that would be detrimental to the existing character
of the neighborhood. Rooftop and utility pole applications are favored where the design can be
screened or incorporated into the existing structure and mechanical equipment can be placed
out of view.
After viewing the area, the candidates considered for location, included various rooftops and
utility poles surrounding Edmonds Ave. near proposed site location.
Two coverage plots are attached. The first demonstrates the existing level of service. The
second plot demonstrates the service that will be provided by the new location at a height of 57'-
8" (antenna centerline). The colors on the map indicate the different levels of coverage.
The legend of the prediction plot shows several different classes of best servers. The various
colors of the plot indicate where a T-mobile handset can be reliably used to make and receive
telephone calls in the presence of varying receive signals. The terrain, foliage, nearby
structures, and WCF location are taken into account. The further the distance from the WCF, or
the more abundant the clutter (trees, buildings, etc.) between the WCF and the handset, the
weaker the receive signal will be. The following is a short explanation of each server class/
color:
Green: Indoor coverage represented by receive signals equal to or greater than
-76 dBm
Yellow: In-Vehicle and outdoor coverage are represented by receive signals greater
than or equal to -84 dBm.
White: No coverage or unreliable coverage
The various parameters of the model used include terrain and clutter and are modified to more
accurately reflect the actual terrain and topography effects of the specific location on the radio
coverage predictions.
Other factors, not represented on the plot, include the ability of the site to handle the required
call capacity or volume of calls and to provide the extent of data and other services required by
T-Mobile customers. This site has been designed to provide coverage consistent with these
factors. Finally, T-Mobile RF engineers have determined that this height and location is
necessary for the effective functioning of the minor communication utility.

Enhanced 911 (E911l Requirements
In addition to providing improved service to T-Mobile customers, the proposed antenna location
is needed to meet Federal Communications Commission (FCC) requirements for Enhanced 911
(E911) service. The wireless E911 program is divided into two phases. Phase I requires
wireless carriers, upon request from a local Public Safety Answering Point (PSAP), to report the
telephone number of a wireless 911 caller and the location of the antenna that received the call.
Phase II of the E911 program requires wireless carriers to provide far more precise location
information, within 50 to 100 meters in most cases.
The FCC established a four-year schedule for Phase II. It began on October 1, 2001 with a
target completion date of December 31, 2005. Provision of E911 service in accordance with
FCC requirements is a major component of the demand for additional cell sites. In addition to
providing greater signal strength for in-building coverage that will provide better service to
residential customers in the area, the proposed WCF will provide more precise triangulation for
providing E911 service as required by the FCC. This will allow a person who is using E911
because of an emergency to be found more quickly because their location will be more easily
determined as this and other antenna sites are added to the wireless network.
Conclusion
T-Mobile engineers have carefully designed this site to max1m1ze quality of service to our
customers, which can best be accomplished at a height of 57'-8" (antenna center line). 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. Good site geometry is needed to achieve accurate location of mobile users
through triangulation with existing and proposed sites.
RELATED INFORMATION
About T-Mobile's Wireless Network
T-Mobile operates the largest all digital, nationwide wireless network based on the globally
dominant GSM (Global System for Mobile Communications) technology. T-Mobile's entire
network has been enhanced to provide customers wireless Internet access and operates the
largest carrier owned "Wi-Fi" wireless broadband network in the world with service in over 5,100
public locations under the name T-Mobile HotSpot'm.
Overview of Wireless Technology
Wireless service operates through cellular radio telephone networks, which are comprised of
thousands of cell antenna sites, switching facilities and other network elements. All cell antenna
sites are radio frequency (RF) transmission towers operating at different frequencies. Each
wireless carrier is assigned a very limited amount of frequency, which is divided into certain
number of RF channels. RF Channels are assigned to each of the cell sites for communication
with our handheld wireless phones. Since the number of channels is very limited, they have to
be reused at different cell sites. The problem with reusing RF channels is the potential for
RF Documentation for SE04810A Edmonds Ave
Page 4 of7
interference. When a cell site is using the same RF channel as another cell site nearby this can
cause interference. Sometimes when you use a cell phone you may hear a metallic sound or
wobbling. This is probably caused by interference.
In order to minimize the interference from one site to another site that are using the same RF
channel, all cell sites transmit at very low power level. The output of the wireless cabinet is
typically about 20 Watts. The RF emissions from a wireless antenna site are very minimal
compared to the output power of other RF equipment. For example, TV antenna towers power
output is in excess of 1000 Watts. Due to the low-level power output of wireless antennas, each
cell site covers only a very limited area. In order to provide consistent, homogenous, quality
wireless service, cell antenna sites is normally less than one mile apart. The exact distance
required between cell antenna sites is determined by terrain, blockage from structures, call
volume and antenna height.
How does a wireless antenna work and what is its function?
Wireless antennas send and receive radio signals. The RF carries the phone call to or from a
wireless base station antenna that then connects your phone with the phone you are calling or
with the phone calling you. Engineers carefully design each antenna to make sure it sends
signals in precisely the right direction and at the right power level to provide the best calling
quality to its coverage zone or "cell area." It is important to note the difference between
antennas, towers and base stations. Antennas transmit the RF and are attached to structures
such as buildings or towers. The antennas, towers and all of the related equipment make up a
cell site.
Cells, or coverage areas, come in all sizes -they may be as small as a single building (like an
airport or an arena), as large as a rural area of 20 miles across, or any size in between -and
each cell has its own base station.
When you place a wireless call, your phone uses low-power radio signals to send your voice to
an antenna at a base station. The base station sends your call to a switching center where it is
connected to the landline phone network and delivered to the phone you called. If you are
calling another wireless phone nearby, the switch might just connect you directly to another
base station in the cell where the other phone is located. When you approach the boundary of
one cell while using your wireless phone, the wireless network senses that the signal is
becoming weak and automatically hands off the call to a base station in the next cell and your
call continues uninterrupted.
An antenna distributes radio waves throughout its cell much like a lamp distributes light
throughout a room. A light bulb can provide light evenly throughout a room if it's located in the
right place. In the same way, a properly located antenna can provide high-quality calling
throughout its cell. That's why they're usually found above the ground on towers, poles, and
buildings.
Apart from improving service to T-Mobile's existing customer base, T-Mobile has experienced
phenomenal growth in the last few years, with an average national customer growth rate of
almost 40% per year. It is not unusual for T-Mobile to add more than a million nationwide
customers per quarter. T-Mobile forecasts this phenomenal growth to continue. T-Mobile's
system design accounts for this predicted growth.

Project Proposal: T-Mobile Monopole I on 27th Street
Site Address: 2424 NE 27th Street, Renton, WA
Project Narrative
T-Mobile proposes a new wireless communications facility at the location of 2424 NE 27th Street. Site is
located within Residential-8 (R-8) zoning designation. The site is 1.99 acres in size and currently houses
at 3,552 square foot social hall maintained by the Living Memorial Association of Kennydale. The WCF
would be located at the northern side of the existing building on site. There is an existing ravine on the
NE section of the parcel that runs from the NW to the SE. The presence of the ravine does not affect
planned proposal as the site is positioned directly adjacent to the existing building within its building
shadow. Proposed site can be accessed from either the SW or SE access point on the parcel. There is
ample parking space within the existing parking lot, adjacent to the site to the north, or adjacent to the
building on the west.
The proposed WCF will be used for the transmission and reception of radio frequency signals for
reception and transmission of radio frequency signals for cell phone coverage in the surrounding
residential area of Kennydale. It is comprised of a 59'11" flush mount monopole, as well as 4 associated
radio cabinets positioned on a 10'x15' pad at the base of the tower.WCF would comprise a total area of
ll'x22', wholly enclosed by a chain link fence with tan privacy slats for maximum screening. No
landscaping is proposed due to the fact that it would hinder use of the parking lot and limit access
across the eastern portion of the lot.
Proposed WCF would contain maximum screening requirements allowed under the existing technology.
No existing trees will be affected or moved by the proposed construction of the WCF. Furthermore, the
monopole is proposed to be less than 60' in height, well below the 100' tree line that exists on the
property. The site is also highly shielded by existing trees to the west and east of the proposed area. The
monopole itself is proposed to have flush mount antennas painted to match the green color of the
tower.
Per RMC 4-4-140(G), a monopole I WCF is an allowed used within the R-8 zoning via Hearing Examiner
Conditional Use permit, provided that the site is over one acre in size and the facility has a minimum
setback of 100' from any adjacent residentially zoned parcel. The proposed project adheres to the
required scope as noted under the code. The project also requires SEPA determination due to the
proposed presence of a WCF on residentially zoned property. SEPA checklist is included with permit
submittal. The structure is designed to have the structural capability to hold the equipment of three
carriers, including T-Mobile, and T-Mobile will allow collocation on the proposed structure per
requirement by RMC.
Geotechnical reports are performed by a 3'' party on all new WCFs that T-Mobile installs. Since land use
reviews focus on the concept of a proposal rather than its constructability, we believe this report is most
effective when it is performed at time of building permit submittal.
Construction costs are estimated at $100,000 for the pole and installation. No excavation is required.

Project Proposal: T-Mobile Monopole I on 27th Street
Site Address: 2424 NE 27th Street, Renton, WA
Conditional Use Permit Justification
T-Mobile's wireless network currently has a large coverage gap serving the residential Kennydale area
within the city of Renton (see Exhibits A and BJ. This area is located northeast of the intersection of 1-405
and Highway 900 and southwest of the border of Newcastle. Currently T-Mobile serves much of this
area of Kennydale through commercially zoned sites along the freeway system: two sites along the 1-405
corridor and two additional sites along Highway 900. Due to the dense nature of the residential zoning
in the area, there are no existing commercial or industrial zoned parcels available to adequately affect
coverage in the subject area. Currently, T-Mobile is not able to provide adequate phone, data, and E-911
services to the subject area.
The following Special Decision Criteria For Wireless Communication Facilities are defined are addressed
below:
1. Height of the proposed tower.
Response: Height Is proposed at 59' 11 '1
2. Proximity of the tower to residential structures and residential district boundaries.
Response: The closest residential structure is approximately 150' away and seporoted by multiple
evergreen trees.
3. Nature of uses on adjacent and nearby property.
Response: The subject property sen,es as public use for the U11/ng Memorial Assodation of Kennydale.
Property to the North and East is undeveloped and w/1/ llkely remain so due to the topography of the
land. Uses to the West and South are resident/al.
4. Surrounding topography.
Response: The subject property has very stable grade surrounding the project area. The northeastern
section of the parcel has more substantial topography changes.
5. Surrounding tree coverage and foliage.
Response: The subject property currently has significant tree coverage an the western, northern, and
eastern sections.
6. Design of the tower, with particular reference to design characteristics that have the effect of
reducing or eliminating visual obtrusiveness.
Response: The tower is designed for a minimal height of 59'11". The proposed structure would utilize
stealth methods such as flush mounting of antennas and uniform equipment point sa as to blend in
with the natural surroundings. Ground equipment is proposed to be fenced and iKreened with vinyl
privacy slats for minimal visual impact as well as minimal effect on the current use of the property.
7. Proposed ingress and egress.
Response: Proposed ingress and egress can be utilized with the SW and SE access portions of the
parcel.
8. Potential noise, light and glare impacts.
Response: As noted In our provided Noise Study, equipment noise Is limited to 38 dBA at the nearest
receiving property which is within compliance of the 47 dBA code limit set by the City of Renton. No
light and glare Impacts will be applicable under the current proposed design.
9. Availability of suitable existing towers and other structures.
The only available structures In the area are located along sections of 1-405 to the west and Highway
900 to the south. T-Moblle currently has multiple existing sites in these areas. T-Mobile is still unable
to seflle the subject residential Kennydale area with the noted existing structures.
10. Compatibility with the general purpose, goals, objectives and standards of the Comprehensive Plan,
the Zoning Ordinance and any other plan, program, map or ordinance of the City.
Response: In the 2008 Utilities Supplement to the Renton Comprehensive plan, the city recognizes the
changing structure and importance of a complete cellular network. The section notes, u As cell sites
were initially developed, a few large cells were established using hilltops or tall buildings to site
transmission and receiving antennas. This allowed for maximum coverage of the large cell. Ousters of
smaller cells hove since replaced the larger configuration •.• Thus, shorter antennas and poles provide
coverage for the smaller cell sites. This division of cells will continue to occur os the demand for
cellular sefllice grows.» As a result, T-Mobile bell eves that the current proposal adheres to the spirit of
the Comprehensive Plan.
The proposed site adheres to the goals of the Renton Municipal code as defined in RMC 4-4-140:
1. Encourage the location of towers in non-residential areas and minimize the total number of towers
throughout the community.
Response: T-Mobile has utilized existing non-resident/al sites in order to maximize coverage to the
Kennydale area. These sites still leave a very large coverage gap within the subject residential area in
Kennydole. (See Exhibit A}
2. Encourage strongly the joint use of new and existing tower sites.
Response: The proposed site will be structurally capable of holding 3 carriers including T-Moblle. T-
Mobile would cooperate with other carriers seeking collocation on the proposed WCF.
3. Encourage users of towers and antennas to locate them, to the extent possible, in areas where the
adverse impact on the community is minimal.
Response: The proposed WCF would be located on o parcel that cu"ently serves as a public use for the
community. The WCF would also adhere to all FCC requirements and regulations. Our provided Noise
Study and NIER report furthermore show that the proposed WCF would be within compliance of
applicable noise ond health requirements.
4. Encourage users of towers and antennas to configure them in a way that minimizes the adverse visual
impact of the towers and antennas.
Response: The proposed WCF would be located near a tree line at the northern edge of the subject
Kennydale neighborhood. It would also be surrounded by trees to the north, east and western sides.
Furthermore, the proposed structure would utlllze stealth methods such as flush mounting of antennas
and uniform equipment paint so as to blend In with the natural surroundings. Ground equipment is
proposed to be fenced and screened with vinyl privacy slats for minimal visual impact as well as
minimal effect on the current use of the property.
5. Enhance the ability of the providers of telecommunications services to provide such services to the
community quickly, effectively, and efficiently.
Response: Currently, T-Mobile is not able to adequately serve the subject Kennydale neighborhood. As
part of the Federal Communications Commission's mandate for E-911, wireless carriers are required to
be able to locate a call from a wireless phone to an increasingly accurate geo-location. In order to
meet these emergency location requirements some carriers, induding T-Mobile, need to maintain as
complete a network as possible. Creating a network of cell sites, with a wireless tower or antenna at
its core, also helps eliminate consumer service problems like dropped calls, no signal, or poor quality.
Only with this infrastructure in place can consumers receive the quality and geographic coverage they
expect from their wireless services. Allowance of the proposed WCF would enable T-Mobile to provide
adequate phone, data, and E-911 services to an otherwise underserved residential area.
Thank you for your consideration of the information provided in support of permit justification.

RE: T-Mobile CUP application for proposed WCF at 2424 NE 27'h Street --Landscaping
To Whom It May Concern,
On behalf of the Living Memorial Association of Kennydale, I would like to relay our landscaping
preference as owner of the subject parcel at address 2424 NE 27th Street in the city of Renton. The
current design for the ground equipment of the proposed WCF includes a chain link fence with vinyl
privacy slats that would entirely screen the ground equipment. Furthermore, the equipment location
would be adequately screened from view by other parcels utilizing existing site conditions. More
specifically, it would be screened from street view due to the location behind the existing building, and
further screened by surrounding trees to the north, west and east. Finally, a requirement for
landscaping would unnecessarily limit use of the property. The current site design minimizes impact on
the property and any landscaping would unnecessarily reduce parking and access to the rear parking
area.
Thank you for your consideration.
Sincerely,
Gary Bagnall
Living Memorial Association of Kennydale

Aeronautical Study No.
2008-ANM-2661-0E
** DETERMINATION OF NO HAZARD TO AIR NAVIGATION**
The Federal Aviation Administration has conducted an aeronautical study under the provisions of 49 U.S.C.,
Section 44718 and if applicable Title 14 of the Code of Federal Regulations, part 77, concerning:
Structure:
Location:
Latitude:
Longitude:
Heights:
Antenna Tower SE04810A
Renton, WA
47-30-57.80N NAD 83
122-11-10.56W
60 feet above ground level (AGL)
380 feet above mean sea level (AMSL)
This aeronautical study revealed that the structure would have no substantial adverse effect on the safe
and efficient utilization of the navigable airspace by aircraft or on the operation of air navigation facilities.
Therefore, pursuant to the authority delegated to me, it is hereby determined that the structure would not be a
hazard to air navigation provided the following condition(s) is(are) met:
See attachment for additional condition(s) or information.
Based on this evaluation, marking and lighting are not necessary for aviation safety. However, if marking
and/or lighting are accomplished on a voluntary basis, we recommend it be installed and maintained in
accordance with FAA Advisory circular 70/7 460-1 K Change 2.
This determination expires on 05/14/2010 unless:
(a) extended, revised or terminated by the issuing office.
(b) the construction is subject to the licensing authority of the Federal Communications Commission
(FCC) and an application for a construction permit has been filed, as required by the FCC, within
6 months of the date of this determination. In such case, the determination expires on the date
prescribed by the FCC for completion of construction, or the date the FCC denies the application.
NOTE: REQUEST FOR EXTENSION OF THE EFFECTIVE PERIOD OF THIS DETERMINATION
MUST BE POSTMARKED OR DELIVERED TO THIS OFFICE AT LEAST 15 DAYS PRIOR TO THE
EXPIRATION DA TE.
Page 1 of7
This determination is subject to review if an interested party files a petition that is received by the FAA on or
before December 14, 2008. In the event a petition for review is filed, it must contain a full statement of the basis
upon which it is made and be submitted in triplicate to the Manager, Airspace and Rules Division -Room 423,
Federal Aviation Administration, 800 Independence Ave., Washington, D.C. 20591.
This determination becomes final on December 24, 2008 unless a petition is timely filed. In which case, this
determination will not become final pending disposition of the petition. Interested parties will be notified of the
grant of any review. For any questions regarding your petition, please contact Office of Airspace and Rules via
telephone --202-267-8783 -or facsimile 202-267-9328.
This determination is based, in part, on the foregoing description which includes specific coordinates, heights,
frequency(ies) and power. Any changes in coordinates, heights, and frequencies or use of greater power will
void this determination. Any future construction or alteration, including increase to heights, power, or the
addition of other transmitters, requires separate notice to the FAA.
This determination does include temporary construction equipment such as cranes, derricks, etc., which may be
used during actual construction of the structure. However, this equipment shall not exceed the overall heights as
indicated above. Equipment which has a height greater than the studied structure requires separate notice to the
FAA.
This determination concerns the effect of this structure on the safe and efficient use of navigable airspace
by aircraft and does not relieve the sponsor of compliance responsibilities relating to any law, ordinance, or
regulation of any Federal, State, or local government body.
This aeronautical study considered and analyzed the impact on existing and proposed arrival, departure, and
en route procedures for aircraft operating under both visual flight rules and instrument flight rules; the impact
on all existing and planned public-use airports, military airports and aeronautical facilities; and the cumulative
impact resulting from the studied structure when combined with the impact of other existing or proposed
structures. The study disclosed that the described structure would have no substantial adverse effect on air
navigation.
An account of the study findings, aeronautical objections received by the FAA during the study (if any), and the
basis for the FAA's decision in this matter can be found on the following page(s).
A copy of this determination will be forwarded to the Federal Communications Commission if the structure is
subject to their licensing authority.

DATE: January 5, 2009
PREPARED BY:

PROJECT
The proposed T-Mobile project consists of a WCF (Wireless Communications
Facility) with BTS equipment located at 2424 NE 27u, St, Renton, WA 98056,
King County parcel number 3343900005. The planned improvements include
antennas on a 59'-11' AGL steel monopole with supporting BTS (Base
Transmission System) radio equipment localed in a fenced lease area near the
base of the monopole on private property.
EQUIPMENT
Type of Service: Broadband PCS/AWS
Antennas: Andrew TMBXX-6516-R2M (1 per sector)
Sectors: 3 (alpha= 80°, beta= 180°, gamma= 280°)
Frequencies: PCS Send (1965 Mhz -1975 Mhz, 1980 Mhz-1985 Mhz)
Receive (1885 Mhz -1895 Mhz, 1900 Mhz-1905 Mhz)
AWS Send (2145 Mhz -2155)
Receive (1745 Mhz-1755)
Maximum Power: 432 w/channel ERP (58.5 dBm/channel EIRP)
Maximum Channels: 4 per sector
Antenna Rad Center: 57'-8" AGL
CALCULATIONS
Calculations for RF power densities near ground level are based on the
"Evaluating Compliance with FCC Guidelines for Human Exposure to Radio
Frequency Electromagnetic Fields OET Bulletin 65" Edition 97-01, August
1997 issued by the Federal Communications Commission Office of Engineering
& Technology.
Section 2 of OET Bulletln 65 demonstrates that "for a truly worst-case prediction
of power density at or near the surface, such as at ground-level or on a rooftop,
100% reflection of incoming radiation can be assumed, resulting in a potential
doubling of predicted field strength and a four-fold increase in (far field
equivalent) power density''. Therefore the following equation Is used:
S = EIRP/rrR2
Where S = power density (mW/cm2 ), EIRP = equivalent isotropically radiated
power and R = distance to the center of the radiation antenna (cm)
Attached as an exhibit are the MPE (Maximum Power Exposure) calculations
using the above referenced formula and the antenna manufacturers product data
information with dB loss data below main lobe as provided by the manufacturer.
The calculations show that the maximum MPE at ground level (6' above AGL)
occurs with the TMBXX antennas at a minor lobe angle of 41 °, 59' from the base
of the monopole and the power density is 0.006843 mW/cm2 with 4 channels
operating at a total ERP of 1,726 watts. This is 0.06843% of the MPE limit for
the general population/uncontrolled exposure of 1.0 mW/cm• as referenced in
Table I OET Bulletin 65 Appendix A.
ENVIRONMENTAL EVALUATION
Routine environmental evaluation is required if the PCS broadband facility is less
than 10 m (32.81 feet) AGL and has a total power of all channels in any given
sector greater than 2,000W ERP as referenced in "Table 2 Transmitters,
Faclllties and Operations subject to Routine envlronmental Evaluation" of
Bulletln 65. As the proposed antennas lowest point above ground level is
16.9 m (55.4 feet), the WCF is categorically exempt from requirement for routine
environmental processing.
FCC COMPLIANCE
The general population/uncontrolled exposure near the monopole, including
persons at ground level, surrounding properties, inside and on existing structures
will have RF exposure much lower than the "worst case" scenario, which is a
small fraction of the MPE limit.
Only trained persons will be allowed to climb the monopole for maintenance
operations. T-Mobile and/or its contractors will provide training to make the
employees fully aware of the potential for RF exposure occupational training and
they can exercise control over their exposure that is within the
occupational/controlled limits.
CONCLUSIONS
Based on calculations, the proposed WCF will comply with current FCC and
county guidelines for human exposure to radiofrequency electromagnetic fields.
All representations contained herein are true to the best of my knowledge.

T-Mobile telecommunications facility at 2424 NE 27th Street in Renton, Washington. This
noise survey extends from the proposed equipment to the nearest properties. The purpose
of this report is to document the existing conditions and the impacts of the acoustical
changes due to the proposed equipment. This report contains data on the existing and
predicted noise environments, impact criteria and an evaluation of the predicted sound levels
as they relate to the criteria.
Ambient Conditions
Existing ambient noise levels were measured on site with a Larson-Davis 820 sound level
meter on January 26, 2009. Measurements were conducted as close to the proposed
location as possible and the property lines in accordance with the State of Washington code
for Maximum Environmental Noise Levels WAC 173-60-020. The average ambient noise
level was 54 dBA, due primarily to local traffic on NE 27th Street. The weather during the
measurements was clear and the roads were dry.
Code Requirements
The site is located within the City of Renton Zoning jurisdiction. The property within a
residential zone, but is used for commercial, non-residential purposes. The receiving
properties are all residential, within the same residential zone.
The proposed new equipment consists of equipment support cabinets, which are expected to
run 24 hours a day.
Renton Municipal Code Chapter 8-7-2 adopts by reference Washington Administrative Code
Sections 173-60-020, 040, 050, and 090, and further identifies properties used for
miscellaneous commercial services and recreation/entertainment purposes, not for human
habitation, as Class B EDNA. The adjacent Residential properties are designated as Class
A EDNA. Under WAC 173-60-040, noise from equipment on a Class B EDNA property is
limited as follows:
SSA Acoustics, LLP
222 Etruria Street, Ste 100
Seattle, Washington 98109
t. 206.839.0819 f. 206.839.0824
T-Mobile West
WE04810A Edmonds Ave NE/Living Mem
Class A EDNA Receiver: Noise is limited to 57 dBA during daytime hours. During nighttime,
defined as the hours between 10 p.m. and 7 a.m., maximum sound levels are reduced by 10
dBA for receiving properties within Class A EDNA's. Since the support cabinets are
expected to operate 24 hours a day, they must meet the 47 dBA nighttime limit.
Predicted Equipment Sound Levels
The proposed equipment includes two Nokia Ultrasite Cabinets 1 , one Purcell Power
Cabinet', and one Nokia Flexi UMTS Cabinet 3 • The combined sound pressure level from all
of the equipment is 69 dBA at a distance of 3 feet.
To predict equipment noise levels at the receiving properties, this survey used the methods
established by ARI Standard 275-97. Application factors such as location, height, and
reflective surfaces are accounted for in predicting the sound level at the nearest receivers.
The nearest receiving property is 117-feet west of the equipment location. The proposed
equipment is to be located on the north side of an existing building on a concrete equipment
pad surrounded by a 6-foot chain link fence. The predicted sound level at the nearest
receiving property is shown in Table 1 below.

lnverse-Sauare Law (Free Field): DF = 20lon /d1/d2l (117ft)
3 New Equipment Sound Pressure Level at Receiver, Lpr 38 /Add lines 1 and 2)
As shown in Table 1, the combined sound pressure level from the proposed equipment
cabinets is predicted to be 38 dBA at the nearest receiving property. This complies with the
47 dBA code limit set by the city. Since the equipment noise will be loudest at the nearest
receiving property line, the noise limits will be met at all other receiving property lines as well.
No further mitigation will be necessary to meet code. If you have any questions or require
more information, please feel free to call.
Sincerely,
