amenity features. The proposal is compliant with the following Comprehensive Plan Goals and
Policies if all conditions of approval are met:
Compliance Comprehensive Plan Analysis
Policy U‐79. Require that the siting and location of telecommunications facilities be
accomplished in a manner that minimizes adverse impacts on the environment and
adjacent land uses.
Policy U‐80. Require wireless communication structures and towers to be designed and
site to minimize aesthetic impacts and to be co-located on existing structures and towers
wherever possible.
Goal L-BB: Maintain a high quality of life as Renton grows by ensuring that new
development is designed to be functional and attractive.
Goal L-FF: Strengthen the visual identity of Renton and its Community Planning Areas
and neighborhoods through quality design and development.
14. Zoning Development Standard Compliance: The site is located in the Urban Center (UC) Zone and
in the Urban Design District C on the City’s Zoning Map. Land with the UC zoning designation is
intended to provide an area for pedestrian-scale urban mixed-use development that supports the
residential and employment goals of Renton’s Urban Center. The UC Zone is intended to attract a
wide range of office, technology, commercial, and residential uses. The overall mix and intensity
of uses is intended to create an urban rather than suburban character. The purpose of the design
requirements in Urban Design District C is to encourage high-quality, pedestrian-scale structures
in areas zoned Urban Center (UC) or Commercial Office Residential (COR). Although the design
requirements for structures in Urban Design District C are not applicable to wireless
communication facilities, the design and siting of new towers or equipment should be compatible
with the goals and overall intent of the design regulations. All new wireless communication
facilities are required to meet the standards and requirements in RMC 4-4-140 in lieu of the typical
development standards based on zoning designation.

i. Architectural integration is required (if applicable).
ii. To the extent feasible, generators shall be enclosed along with the related
equipment. Similar to equipment shelters, the screening for the generator
shall utilize similar building materials, colors, accents, and textures as the
primary building; if no buildings exist on site, ensure that the building is
designed to blend in with the environment.
iii. A screening wall and/or landscaping material shall be required to mitigate
visual impacts.
iv. Fences shall be constructed of materials that complement and blend in
with the surroundings.
v. Anti-graffiti finish shall be applied to all solid fences, walls, and gates.
vi. A noise analysis shall be required to demonstrate that the generator will
operate within allowed noise limits if the generator is the sole power
source.
Staff Comment: The applicant is proposing to locate the stealth tower and
associated equipment on the northwest corner of the site, within the existing
parking lot. The applicant is proposing to enclose the stealth tower and equipment
with a new, four sided, 8-foot tall fence, which would eliminate 2 existing parking
spaces, and occupy approximately 300 square feet. A generator is included in the
proposal and would also be located within and screened by the enclosure. The
applicant proposes chain link fencing with opaque screening along the north and
east faces of the enclosure, and sound barrier fencing along the south and west
faces.
The new stealth tower enclosure would be bordered by existing off-site ROW
landscaping to the north and offsite trees, landscaping, and parking to the west. The
existing trees and landscaping serve as a visual barrier to the west. The stealth tower
and enclosure would remain visible to the north from N 3rd St, which can be improved
with additional landscaping to the north, including trees and shrubs. In addition, the
applicant’s proposal does not include required landscape screening around the
proposed enclosure. Due to high visibility from N 3rd St and the requirements in the
Design Standards of Urban Design District C, Service Element Location and Design
section, higher quality screening materials should be used to help mitigate the visual
impact of the equipment enclosure. The addition of landscape screening around the
enclosure, as required by RMC 4-4-140.F(1)(a), would also help improve the visual
appearance of the enclosure. The applicant may not be able to provide 15 feet of
landscape screening around all four sides of the enclosure, but should add 15 feet of
landscaping on the north, east, and south sides, where feasible. Landscaping within
the public right of way, or on the neighboring property to the west may be necessary
to comply with landscape screening requirements. Therefore, Staff recommends as
a condition of approval that the applicant revise the enclosure to be made of
masonry, ornamental metal, or wood or some combination of the three. In addition,
Staff recommends a condition of approval that the applicant submit a landscape
plan that shows 15 feet of landscaping along the north and south sides of the
enclosure, and along the east side of the enclosure where it will not conflict with the
enclosure opening. The applicant shall work with the City Community Services

Department, to determine if additional landscaping could be placed within the
public right of way and neighboring property to the northwest.
A generator is proposed with the project application. See FOF 14.e for more
information on noise levels.
Shall comply
using the CUP
Criteria below
under FOF 19.a
b. Maximum Height: The maximum building height permitted in the UC zone is 10
stories along primary and secondary arterials, and 6 stories along residential/minor
collectors. The maximum height of wireless communication facilities is governed by
RMC 4-4-140F, which permits a maximum height of 150 feet for stealth towers, if
approved through the CUP process. Allowed heights for specific types of stealth
facilities shall be determined through the Conditional Use Permit review process.
Staff Comment: The maximum height of the proposed stealth tower with monopine
branches is 59.9 feet. The proposal complies with the maximum height permitted in
the UC zone. The height requirements of RMC 4-4-140F are evaluated below in
Conditional Use Permit analysis for height, FOF 16.a.
Compliant if
condition of
approval is met
c. Visual Impact: RMC 4-4-140F.3 requires that site location and development
preserve the pre-existing character of the surrounding buildings and landscape to
the extent consistent with the function of the communications equipment. Towers
shall be integrated through location and design to blend in with the existing
characteristics of the site to the extent practical. Existing on-site vegetation shall be
preserved or improved, and disturbance of the existing topography shall be
minimized, unless such disturbance would result in less adverse visual impact to the
surrounding area. Towers, antennas and related equipment shall be uniformly
painted a non-reflective neutral color that best matches the colors within the
immediately surrounding built and natural landscape in order to reduce the
contrast between the WCF and the landscape.
Staff Comment: The site of the proposed faux tree stealth tower is located within
two (2) existing parking spaces and abuts existing landscape planters (with existing
fir and pine trees) to the west. The existing off-site landscaping to the west includes
mature Douglas Fir and White Pine trees. Approximately nine (9) trees are within
100 feet of the faux tree. The closest tree is within approximately 35 feet of the
proposed stealth tower location. The existing off-site trees range in size from 10 feet
in height to 69 feet in height. The proposed stealth tower design and location is
intended to disguise the tower as an average tree within the existing tree grouping,
without compromising the health of the existing trees. The scale of the faux tree
stealth tower will be compatible with existing trees and characteristics of the site.
Revisions to the proposed equipment enclosure will further mitigate the visual
impact of the stealth tower. See analysis for design provided in FOF 14.a and FOF
14.k with associated conditions of approval.
Compliance not
yet
demonstrated
d. Setbacks: RMC 4-4-140F.4 requires that towers be set back from each property
line by a distance equal to the tower height, unless an engineering analysis
concludes that a reduced setback is safe for abutting properties and the
Administrator determines that a reduced setback is appropriate for the site.
Staff Comment: The proposed stealth tower and enclosure would be located on the
northwest corner of the existing parking lot, in close proximity to existing fir and

VERIZON SEA LOGAN AVENUE LUA17-000866, CU-A
March 8, 2018 Page 8 of 15
D_Administrative_Report_Verizon_Sea_Logan_Ave_180308
pine trees in order to reduce the visual impact of the stealth tower. The proposed
fencing for the enclosure would be located along the west and northwest property
lines. The tower and enclosure would be setback approximately 189 feet from the
east property line (Burnett Ave N) and 219 feet from the south property line, which
complies with code requirements. The equipment within the enclosure is setback
1.25 feet from the west property line and 0.5 feet from the northwest property line.
The faux tree support structure would be setback from the west and northwest
property lines a minimum 9.5 feet and the dripline of the faux tree would be setback
from the west and northwest property lines a minimum 5 feet. Staff agrees that a
reduced setback is appropriate for the site given the proximity to existing trees.
Therefore, Staff recommends a condition of approval that the applicant submit an
engineering analysis to ensure the safety of nearby.
Compliant if
condition of
approval is met
e. Maximum Noise Levels: RMC 4-4-140F.5 limits the noise of equipment associated
with Wireless Communication Facilities to forty five (45) decibels as measured from
the nearest property line on which the facility is located. Operation of a back-up
power generator in the event of power failure or the testing of a back-up generator
between eight o’clock (8:00) a.m. and nine o’clock (9:00) p.m. are exempt from this
standard. No testing of back-up generators shall occur between the hours of nine
o’clock (9:00) p.m. and eight o’clock (8:00) a.m.
Staff Comment: The proposed new equipment for the stealth tower includes
equipment support cabinets and an emergency generator. The equipment support
cabinets are expected to run 24 hours a day. The generator will run once a week
during daytime hours for maintenance and testing purposes only. The nearest
receiving properties are approximately 45 feet south, and 6 feet west of the
equipment cabinets. The applicant submitted an Acoustical Report prepared by SSA
Acoustics (dated December 28, 2017; Exhibit 7) with the project application. The
report states that with proposed mitigation (noise barrier fencing), the proposed
emergency generator will reach a maximum sound pressure level of 62 decibels,
which complies with the day-time code limit during test cycle operations per WAC
173-60-040. In addition, with mitigation the proposed equipment cabinets (that will
run for 24 hours a day) will reach a sound pressure level of 45 decibels to the south
and 47 decibels to the west. As proposed, the equipment cabinets exceed the
maximum limit of 45 decibels for Wireless Communication Facilities (WFCs) per RMC
4-4-140F.5.; therefore, Staff recommends as a condition of approval that the
applicant revises the proposed mitigation measures and submits a revised
Acoustical Report with the building permit application to be reviewed and approved
by the Current Planning Project Manager.
Compliant if
condition of
approval is met
f. Fencing: RMC 4-4-040 limits fences within commercial and industrial zoning to a
maximum height of 8 feet. In addition, RMC 4-4-140F.6 requires the installation of
security fencing coated with a non-reflective neutral fence.
Staff Comment: The height of the proposed security fence enclosing the associated
equipment complies with the City’s adopted fencing requirements. See comments
above under FOF16.a, Equipment Shelter/Cabinets, where staff has recommended
a condition of approval to revise the proposed fencing to comply with Urban Design
City of Renton Department of Community & Economic Development Administrative Report & Decision
VERIZON SEA LOGAN AVENUE LUA17-000866, CU-A
March 8, 2018 Page 9 of 15
D_Administrative_Report_Verizon_Sea_Logan_Ave_180308
Regulations. The new screening would be required to comply with fence and wall
standards of the zone.
g. Lighting: RMC 4-4-140F.7 prohibits the artificial lighting of towers or antennas,
unless required by the FAA or other authority.
Staff Comment: The applicant is proposing two (2) Verizon Wireless LED floodlights
with timers. The application submittal does not indicate the direction of the lighting.
Security lighting for the equipment shelters or cabinets and other on-the-ground
ancillary equipment is permitted provided it is appropriately down shielded to keep
light within the boundaries of the compound. Therefore, Staff recommend as a
condition of approval that the applicant submit a detailed lighting plan and analysis
as part of the building permit submittal.
h. Advertising Prohibited: RMC 4-4-140F.8 prohibits the placement of advertising
on any part of the Wireless Communication Facility or associated equipment.
Staff Comment: The applicant has not proposed any type of advertising to be
included on the structure.
Compliant if
condition of
approval is met
i. Building Standards: RMC 4-4-140F.9 requires support structures to be
constructed so as to meet or exceed the most recent Electronic Industries
Association/Telecommunications Industries Association (EIA/TIA) 222 Revision G
Standard. Prior to issuance of a building permit the Building Official shall be
provided with an engineer’s certification that the support structure’s design meets
or exceeds those standards.
Staff Comment: A Structural Analysis was not submitted with the land use
application. Therefore, Staff recommends as a condition of approval that the
applicant submits an engineer’s certification that the support structure’s design
meets the most recent Electronic Industries Association/Telecommunications
Industries Association (EIA/TIA) 222 Revision G Standard, at the time of building
permit application.
j. Radio Frequency Standards: RMC 4-4-140F.10 requires the applicant to ensure
that the Wireless Communication Facility will not cause localized interference with
the reception of area television or radio broadcasts.
Staff Comment: The applicant does not anticipate any interference with the
reception of the area television or radio broadcasts and would be required to
immediately address any interference issues should they be reported.
Compliant if
condition of
approval is met
k. Stealth Tower Standards:
1. Faux Trees:
a. Location - Faux trees shall be located within one hundred feet (100') of
existing trees, unless photo simulations show, to the Administrator’s
satisfaction, that the proposed faux tree would be appropriate for the site.
b. Height - The faux tree may exceed the average height of nearby trees by no
more than twenty percent (20%) or thirty feet (30'), whichever is greater.
c. Authenticity - Faux trees shall replicate the shape, structure, and color of
live trees common to the area. Plans shall provide detailed specifications
City of Renton Department of Community & Economic Development Administrative Report & Decision
VERIZON SEA LOGAN AVENUE LUA17-000866, CU-A
March 8, 2018 Page 10 of 15
D_Administrative_Report_Verizon_Sea_Logan_Ave_180308
regarding the number and spacing of branches, bark, foliage, and colors. All
faux trees shall incorporate a sufficient number of branches (no less than
three (3) branches per linear foot of height) and design materials (e.g., faux
bark) so that the structure appears as natural in appearance as feasible.
Branches shall not be required for the lowest twenty feet (20') of the trunk.
d. Concealment -
i. All cables and antennas shall be painted to match the color of the trunk.
ii. Antenna socks are mandatory for all antennas (and similar
components) located on a faux tree.
Staff Comment: As stated in FOF 14c., approximately nine (9) trees are within 100
feet of the proposed faux tree. The top of the proposed monopine branches reach a
maximum height of 59.9 feet. The existing off-site trees range in size from 10 feet in
height to 69 feet in height. The average height of the nine (9) closest nearby trees is
38.7 feet. The proposed faux tree does not exceed the maximum difference of 30
feet required by code.
Details regarding the number and spacing of branches, bark and foliage colors,
concealment, or materials were not submitted with the land use application.
Therefore, staff recommend as a condition of approval that the applicant submit a
design analysis demonstrating compliance with these requirements, in addition to
material samples, at the time of building permit submittal.
15. Design Standards: The site is located within Urban Design District C (RMC 4-3-500). As discussed
in FOF 16, the proposed design of the stealth tower should meet the overall intent of the minimum
standards and contribute to achieving the overarching goals of the design regulations, if
conditions of approval are met the stealth tower and associated equipment shelter would meet
the goals of the design regulations. See FOF 14.a and FOF 14.k for Conditional Use Permit analyses.
16. Conditional Use Analysis: In lieu of the criteria normally evaluated for Conditional Use Permits,
the following criteria (RMC 4-9-030E) will be considered in determining whether to issue a
Conditional Use Permit for a wireless communication facility.
Compliance Conditional Use Analysis for Wireless Facilities
a. Height and Design of the Proposed Tower: The maximum height of wireless
communication facilities is governed by RMC 4-4-140F, which permits a maximum
height of 150 feet for stealth towers, however the allowed height for a specific type
of stealth facility shall be determined through the CUP review process. The
maximum height of the proposed monopine (with branches) is 59.9 feet. The
project is exempt from environmental review. The proposed faux tree does not
exceed the maximum difference of 30 feet over the average height of the nearby
trees, which range from 10 feet to 69 feet in height. The proposed height of the faux
tree stealth tower appears to be compatible with the surrounding uses and existing
trees. Therefore, Staff approves a height of 59.9 feet for the proposed faux tree
stealth tower.

March 8, 2018 Page 11 of 15
D_Administrative_Report_Verizon_Sea_Logan_Ave_180308
b. Proximity of The Tower to Residential Structures And Residential District
Boundaries: The proposed stealth tower would be installed on a site zoned UC. The
project site is located in an area intended to provide an area for pedestrian-scale
urban mixed-use development that supports the residential and employment goals
of Renton’s Urban Center. The property is bordered by Burnett Ave N to the east
and N 3rd St to the north. Abutting properties to the west and south are owned by
the City of Renton and are zoned R-10. These properties are occupied by the Renton
Senior Activity Center and associated parking. The closest residential use to the
proposed stealth tower location is a nonconforming single family residential use
located 145 feet to the north, across from N 3rd St. Single family residential homes
located within the R-8 zone are located across Burnett Ave N, approximately 250
feet from the proposed stealth tower location. Due to the distant proximity to
existing adjacent residential uses, and the desired proximity to nearby trees, the
proposed stealth tower location is adequately designed to minimize the visual
impact of the structure, and is compatible with surrounding uses. It is not
anticipated that the faux tree would have impacts on the surrounding uses.
c. Nature of Uses On Adjacent and Nearby Properties: As discussed in FOF 16.b,
Abutting properties to the west and south are zoned R-10 and are occupied by the
Renton Senior Activity Center and associated parking. The proposed location for the
faux tree stealth tower is in close proximity to existing off-site trees, which would
act as a visual barrier between the proposed stealth tower and any future
development. The closest residential uses to the proposed stealth tower location
include a nonconforming single family residential use located 145 feet to the north,
across from N 3rd St, and single family residential homes located approximately 250
feet to the east, across from Burnett Ave N. Stealth towers are designed to blend
into an environment in order to lessen the visual impact on nearby uses. A tower
designed to replicate the look of a tree, in close proximity to other nearby trees, is
appropriate for this area. If the conditions on design are met, Staff does not
anticipate that the proposed stealth tower would have any significant adverse
impacts on the surrounding properties and uses.
d. Topography and Vegetation:
The site is relatively flat. The project excavation envelope for the proposed tower
and associated compound is approximately 300 square feet with an estimated
depth of 1 foot for the construction of concrete slabs for anchorage of ground based
equipment. Proposed excavation of a drilled pier foundation for the tower is
estimated at 6’ x 6’ by 20’ in depth. As a result, estimated excavation volumes are
11 cubic yards for clearing and 25 cubic yards for excavation of tower foundation,
for a total project estimated volume of 36 cubic yards. The fill is predominately
concrete with rebar for the tower foundation and concrete slabs and approximately
5-6 cubic yards in gravel. No tree removal is proposed. Additional vegetation is
required to be added to screen the existing equipment shelter, as conditioned
above under FOF 14.a.
e. Ingress/Egress: Vehicular access to the project site will be provided via existing
driveways off of Burnett Ave N and through the existing parking lot on the site. No
changes are proposed to the existing vehicular access to the project site.

Compliant if
condition of
approval is met
f. Noise, Light, and Glare: As stated in FOF 14.e, the proposal will comply with
maximum noise level requirements if the condition of approval is met. The stealth
tower, designed to replicate a tree, will not produce light. As stated in FOF 14.g, the
applicant is proposing two (2) Verizon Wireless LED floodlights with timers. Staff
has recommended as a condition of approval that the applicant submit a detailed
lighting plan and analysis as part of the building permit submittal that verifies
direction of lighting. As such, if conditions of approval are complied with, impacts
of light and glare are not anticipated to be above what is permitted in the UC Zone.
Compliant if
condition of
approval is met
g. Colocation Feasibility: The applicant submitted satisfactory evidence that no
existing tower or support structure can accommodate the proposed equipment
relocation. The applicant explained that the primary candidate for the new Wireless
Communication Facility (WCF) was the Renton School District’s Renton Memorial
Stadium, where the stadium grandstand is of adequate height and the structure
currently serves as a WCF support structure for another carrier. The applicant
explained that the property owner of Renton Memorial Stadium was not interested
in considering an agreement. In addition, the applicant explained that the ability to
utilize other structures of adequate height in and near the limited service areas is
infeasible due to issues involving availability of the use of structures in the City
ROW. A map showing the limited service area and proposed location is included in
the project description (Exhibit 6). Due to steady growth and development near the
project site and the ever-increasing demand for cellular data, the need for new or
upgraded cellular equipment is likely to grow. In order to provide an opportunity
for the future colocation, new wireless towers should be designed to allow for the
colocation of new equipment in the future. Therefore, Staff recommends that the
proposed stealth tower incorporate space to allow for future colocation efforts as
a condition of approval.
j. Consistency With Plans and Regulations: As previously discussed above under
FOF 13 and 14 the proposed installation of the new stealth tower is consistent with
the City’s adopted Comprehensive Plan, Zoning Ordinance, and RMC 4-4-140
Wireless Communication Facilities regulations provided the conditions of approval
are complied with.
Compliant if
conditions of
approval are met
k. Landscaping: The existing equipment does not employ any type of landscape
screening and the applicant has not proposed any landscaping on the project site.
As previously discussed in FOF 14.a, the addition of landscape around the
equipment enclosure would bring the enclosure closer into compliance with
current code. In addition, adding landscaping elements that help screen the
enclosure would minimize the visual impact of the proposed enclosure. Therefore,
staff recommends that applicant be required to submit a landscape plan for the site
that incorporates screening elements as a condition of approval.
I. CONCLUSIONS:
1. The subject site is located in the Commercial & Mixed Use (CMU) Comprehensive Plan
designation and complies with the goals and policies established with this designation if
conditions of approval are met, see FOF 13.

2. The subject site is located in the Urban Center (UC) zoning designation and complies with the
zoning and development standards established with this designation provided the applicant
complies with City Code and conditions of approval, see FOF 14.
3. The proposed stealth tower meets the ten (10) development standards that apply specifically to
new Wireless Communication Facilities, provided the applicant meets all conditions of approval,
see FOF 14.
4. The proposed stealth tower complies with the Critical Areas Regulations provided the applicant
submit an engineer’s certification that the support structure’s design meets or exceeds the most
recent Electronic Industries Association/Telecommunications Industries Association (EIA/TIA)
222 Revision G Standard, and includes seismic loading analysis for the support structure.
5. The proposed stealth tower meets the nine (9) special decision criteria considered when making
a decision on a conditional use permit request for a Wireless Communications Facility, as
specified in RMC 4-9-030E, provided the applicant meets all conditions of approval, see FOF 16.
J. DECISION:
The Verizon SEA Logan Avenue Condition Use Permit, File No. LUA17-000866, is approved and is subject
to the following conditions:
1. The proposed equipment enclosure shall either be made of masonry, ornamental metal, or
wood, or some combination of the three. A detailed screening plan shall be submitted with the
building permit application for review and approval by the Current Planning Project Manager
prior to building permit issuance.
2. The applicant shall submit a detailed landscape plan that shows 15 feet of landscaping along the
north and south sides of the enclosure, and along the east side of the enclosure where it will not
conflict with the enclosure opening. The detailed landscape plan shall be submitted with the
building permit application for review and approval by the Current Planning Project Manager,
prior to building permit issuance. The applicant shall work with the City’s Community Services
Department to determine if additional off site landscaping (including trees and shrubs) could be
provided to enhance the existing landscaping within the public right of way and the neighboring
property to the northwest, in order to comply with the 15 foot landscape screening regulations.
3. An engineering analysis shall be submitted with the building permit application for review and
approval by the Current Planning Project Manager and the City’s Structural Engineer to ensure
the safety of nearby properties due to the proximity of the proposed faux tree tower.
4. The applicant shall revise the proposed noise mitigation measures to comply with the maximum
limit of 45 decibels for Wireless Communication Facilities per RMC 4-4-140F.5,and submit a
revised Acoustical Report with the building permit application to be review and approved by the
Current Planning Project Manager.
5. The applicant shall submit a detailed lighting plan and analysis with the building permit
application that verifies direction of lighting, to be reviewed and approved by the Current
Planning Project Manager.
6. The applicant shall submit an engineer’s certification that the support structure’s design meets
or exceeds the most recent Electronic Industries Association/Telecommunications Industries

March 8, 2018 Page 15 of 15

EXPIRATION: The Conditional Use Permit decision will expire two (2) years from the date of decision. A
single two (2) year extension may be requested pursuant to RMC 4-9-030.
RECONSIDERATION: Within 14 days of the decision date, any party may request that the decision be
reopened by the approval body. The approval body may modify his decision if material evidence not
readily discoverable prior to the original decision is found or if he finds there was misrepresentation of
fact. After review of the reconsideration request, if the approval body finds sufficient evidence to amend
the original decision, there will be no further extension of the appeal period. Any person wishing to take
further action must file a formal appeal within the 14-day appeal time frame.
THE APPEARANCE OF FAIRNESS DOCTRINE: provides that no ex parte (private one-on-one)
communications may occur concerning the land use decision. The Doctrine applies not only to the initial
decision, but to Appeals to the Hearing Examiner as well. All communications after the
decision/approval date must be made in writing through the Hearing Examiner. All communications are
public record and this permits all interested parties to know the contents of the communication and
would allow them to openly rebut the evidence in writing. Any violation of this doctrine could result in
the invalidation of the appeal by the Court.

RE: Verizon Proposed WCF at SEA Logan Ave
Dear Angelea,
This cover letter is provided regarding the Master Use Application for Conditional Use Permit requested
by Verizon at 231 Burnett Ave N. referenced as Verizon site SEA Logan Ave.
With regard to wireless specific application packet materials, attached are the following:
• Zoning Drawings
• RF Justification Letter
• Maps including RF Planning, Inventory of existing sites, site coverage (before and after)
• Photo simulations
• NIER – FCC Compliance
• Tree Inventory within 100’ of project area
Zoning Drawings - Plans
The attached plans have been revised from a previous version to reflect the proposed use of a faux tree
as the antenna support structure for the proposed Verizon - Wireless Communications Facility (WCF) to
a tower height of 60’. See Project Description in Responses to CUP Submittal Requirements.
A Land Survey is provided in the Project Plans with reference to the Title Report provided and
topographic survey of site.
The proposed project location involves the reduction of 2 existing parking spaces and unused parking
median at the West side of the property parking lot. The proposed location is bounded by landscape
islands on the North and West sides of the property.
RF Justification - Overview
The attached RF Justification Letter was prepared by the assigned Verizon Radio Frequency (RF)
Engineer for the area. The associated maps provide the technical design data for RF Engineering
parameters regarding the Verizon wireless Network at the City cor
Network RF Planning
The issue is that although there is existing coverage in the Renton Core there is not adequate capacity to
provide a level of service needed to meet current demands. As a result, Verizon has planned several
permanent WCF sites in the area - intended to meet and accommodate the demands for adequate
wireless services now and into the future.
RECEIVED
12/29/2017

PLANNING DIVISION
Attached is a map of planned and potential site locations in relation to Verizon existing sites within the
Renton core, that depict the locations of areas that need service improvements called polygons. The
Map is from early 2017, but also includes areas pursued in the past for Network Improvements. The map
includes the approaches over recent months in attempts to secure various types of sites including Small
Cells and Cell on Wheel (COW) deployment. Unfortunately, the Small Cell polygons have been
determined to not be feasible.
As discussed with City representatives in the past, the use of a proposed COW is only a stop gap
measure needed by Verizon to immediate augment the existing RF signal strength in the Renton core
areas needed to provide adequate service while permanent sites are pursued.
As a result, the map shows the permanent locations (Polygons) where RF Engineering has identified
locations where permanent sites are needed.
In this case, the SEA Logan Ave polygon was identified as a candidate search area for a potential
permanent site.
SEA Logan Ave Candidate Selection & Justification
The SEA Logan Ave polygon is located East of the Renton Airport and includes the intersection of Logan
Ave and 3rd Street on its borders.
The primary candidate was the Renton School District’s Renton Memorial Stadium where the stadium
grandstand is of adequate height for a WCF, and the structure currently serves as a WCF support
structure for another carrier. Verizon vigorously pursued the site as the primary candidate for the Logan
Ave polygon however after several months of due diligence with the City and landowner toward a WCF
that meets current codes, the landowner elected to discontinue consideration of the property for a
Verizon WCF. The landowner did not provide an explanation as the basis for their decision therefore
Verizon was not able to mitigate any articulated concerns.
The ability to utilize the other structures of height in and near the polygon were considered and
identified as PSE utility or other poles for possible replacement, however those structures had already
been considered and eliminated due to issues involving availability of the use of structures in the City
R/W.
As a result, a raw land (RL) site type was pursued given the other structures in the area did not have
significant height or had been eliminated in candidate considerations.
Selected Site Considerations
The Carpenter Union property was selected utilizing a RL support structure candidate for several
reasons:
• The property is zoned Urban Center (UC) which is a high impact commercial zone and is the
same zone as the primary candidate.
• The property is located near the intersection of 2 major arterials in the City of Renton.
• There are built structures of height in the area where a WCF support structure will not stand out
as the only built structure of height in the immediate area.
• There are trees in the area that will provide back drop and/or partial visual screening for a
proposed RL structure from adjacent arterials.
• The City zoning codes are conducive to the siting of a RL support structure in the underlying
zone.
Antenna Support Structure Type Considerations
Verizon has worked with planning staff in the candidate scoping and structure type selection. Review of
zoning and other development codes have concluded that the use of a faux tree at the property is the
preferred antenna structure type. A canister type “concealment” support structure was also considered
however staff indicated the faux tree was considered conforming as to the pertinent City Codes.
As a result, a “monopine” tower to 60’ in height was selected as the proposed antenna support
structure with the following considerations:
• There are existing trees in the area where a faux evergreen tree “monopine” appears to be
compatible since it will not standout due to the cluster effect and the existing of evergreen trees
in the general area.
• The proposed structure height at 60’ is adequate in height to provide the needed Line of Site
required for proper function of a WCF at the Polygon, and within the Verizon Network.
• The proposed structure height meets the WAC Exempt from SEPA in the subject zone which
reflects the determined compatibility of such as use in the commercial zone for a WCF support
structure.
• The location is near landscaping meridians that serve as visual and other buffer/berms from
adjacent arterials and assist in screening of the Verizon proposed ground based equipment.
In summary, Verizon believes the CUP Justification findings as stated above and including the following
considerations:
1. All other feasible candidates and existing structures with adequate height have been eliminated
in and near the Polygon.
2. The proposal meets the City of Renton WCF and Development Standards and Codes; all
applicable local, state and federal laws and ordinances.
3. The proposal meets the SEPA WAC exemption for WCF in a Commercial Zone and there are no
known environmental impacts or ECAs at the property, or affected by the proposal.
4. The design meets the criteria for stealth WCF for the zoning regarding proximity to adjacent
zoning districts.
In closing, Verizon is pursuing a Letter from an Engineer that will satisfy the justification of the requested
reduction in setbacks for the tower from adjacent property lines to the North and West. Verizon is also
pursuing a Noise Study Report regarding the conformance of the proposal to City Noise Ordinances.
Those reports are forthcoming and will be provided as soon as they are received.

Re: Acoustical Report – Verizon SEA Logan Ave – Carpenter’s Union
Site: 231 Burnett Avenue N, Renton, WA 98057
Dear Richard,
The following report presents a noise study for the proposed Verizon telecommunications facility
at 231 Burnett Avenue N in Renton, Washington. This noise study 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 Svantek 971 sound level meter on
December 28, 2017. 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 61.2 dBA,
due primarily to traffic noise on Logan Avenue.
Code Requirements
The site is located within the City of Renton Zoning jurisdiction on property designated with a UC
zoning. The nearest receiving properties, to the west and south, are zoned R-10. Renton
Municipal Code 8-7-4 designates UC as Class B EDNA and R-10 as Class A EDNA.
The proposed new equipment includes equipment support cabinets and an emergency generator.
The equipment support cabinets are expected to run 24 hours a day. The generator will run once
a week during daytime hours for maintenance and testing purposes only.
Renton Municipal Code Chapter 8-7-2 adopts Washington Administrative Code Sections 173-60-
020, 173-60-040, 173-60-050 and 173-60-090.
Under WAC 173-60-040, noise from equipment on a Class B EDNA property is limited as follows:
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
Verizon
SEA Logan Ave – Carpenter’s Union
Page 2
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.
Additionally, WAC 173-60-040 allows that during any one-hour period, the maximum permissible
noise level may be exceeded by 5 dBA for a 15 minute period. Therefore, the generator must not
exceed 62 dBA when running during daytime hours for maintenance testing. The generator is
exempt during emergency operation.
Predicted Equipment Sound Levels: 24-Hour Operation Equipment
The following table presents a summary of the equipment and their associated noise levels:
Table 1: Equipment Noise Levels
Equipment dBA (each) Quantity Combined
dBA @ 5 ft
Charles CUBE-SS4D207XNZ which is
equipped with (3) total Delta HET200PB
Thermoelectric Cooling units.
61 dBA @ 3ft 3 61
Charles CUBE-PM63912UNZ which is
equipped with a Dantherm 707893
10,000 BTU Air Conditioner
74 dBA @ 5ft 1 74
Total dBA (All cabinets combined) 74
Methods established by ARI Standard 275-2010 and ASHRAE were used in predicting equipment
noise levels to the receiving properties. Application factors such as location, height, and reflective
surfaces are accounted for in the calculations.
The equipment will be located at grade surrounded by an 8’ tall chain link fence. The nearest
receiving properties are approximately 45 feet south, and 6 feet west of the equipment cabinets.
The following table presents the predicted sound levels:

As shown in Table 2, the sound pressure level from the proposed equipment is predicted to be
55 dBA to the south and 62 dBA to the west, which does not comply with the 47 dBA nighttime
code limit at a residential receiving property. It will be necessary to incorporate a barrier into the
fence in order to reduce noise. Noise levels are expected to comply at all other receiving property
lines.

Predicted Equipment Sound Levels: Emergency Equipment
The proposed equipment includes one Generac SDC20 20 KW generator with a Level 1 sound
enclosure and has a sound level of 65 dBA at 23 feet. The generator will be lo located at grade
surrounded by a chain link fence. The nearest receiving properties are approximately 40 feet
south, and 2 feet west of the generator. The following table shows the predicted sound levels:

(2 ft)
3 New Equipment Sound Pressure Level at Receiver, Lpr
(Add lines 1-2) 60 86
As shown in Table 3, the sound pressure level from the generator is predicted to be 60 dBA at
the to the south, which complies with the 62 dBA code limit to a residential property during test
cycle operation. The sound pressure level is predicted to be 86 dBA to the west, which does not
comply. It will be necessary to mitigate noise by 24 dBA to the west.
Generator Noise Mitigation:
It will be necessary to move the generator 4 feet to the east so that it is no more than 6 feet from
the west property line. The current location is within 2 feet of the property line and will not meet
the noise limits even with a barrier. A barrier will be required as well.
Barrier Design:
The barrier shall be constructed on the west and south sides of the concrete equipment pad per
the following: The new predicted noise levels are shown in Table 4.
1. Construct a noise barrier around the equipment that is at least 8 feet tall, as indicated by
the bold red line in Figure 1. A general detail of the barrier is provided in Figure 2.
2. Construct the noise barrier of a solid material that has a surface mass of 2 lbs/sq ft. (1)
layer of 3/4” exterior grade plywood or (1) layer of 16-gauge sheet metal is approximately
2 lbs/sq ft. It is permitted to add additional material to the outside of the barrier, such as
fence board or siding for aesthetic purposes. However, these added materials cannot
substitute for the required continuous plywood or metal.
3. Line the inside of the noise barrier (side facing cabinets) with a sound absorbing material
that has a minimum NRC rating of 0.50. Weather-resistant materials that meet this
requirement include 2-inch thick exterior grade F-Sorb, available from Forrest Sound
Products (425) 881-1111.
4. Leave no air gaps between joints in the barrier material. All air gaps must be sealed with
a non-hardening acoustical sealant. The most efficient barrier for reducing noise has
materials that are air-tight to create a continuous envelope.
