Policy CF-10: Coordinate with federal, state, regional and local jurisdictions, private
industry, businesses and citizens in the planning, design, and development of facilities
serving and affecting the community.
19. Zoning Development Standard Compliance: The site is classified Light Industrial (IL) on the City’s Zoning
Map. Development in the IL Zone is intended to provide areas for low-intensity manufacturing, industrial
services, distribution, storage, and technical schools. Uses allowed in this zone are generally contained
within buildings. Material and/or equipment used in production are not stored outside. Activities in this
zone do not generate external emissions such as smoke, odor, noise, vibrations, or other nuisances
outside the building The proposal is compliant with the following development standards:
Compliance IL Zone Develop Standards and Analysis
Lot Dimensions: The minimum lot size permitted in the IL zone is 35,000 sq. ft.
Staff Comment: The King County Assessor Office has listed the square footage of the
property at 419,918 square feet.
Setbacks: The required setbacks in the IL zone are as follows: front yard is 20 feet, side
yard is 20 feet, and the rear yard is 20 feet.
Staff Comment: The existing building is setback approximately 195-feet within the front
yard, 197-feet within the west side yard, 226-feet within the east side yard, and 75-feet
within the rear yard.
Building Standards: The IL zone has a maximum building coverage of 65% of total lot
area or 75% if parking is provided within the building or within a parking garage.
Staff Comment: No new building or impervious coverage is proposed with the tower
extension. The coverage (building and impervious) for the existing site is approximately
40 percent.
See FOF 21
building
height
variance
analysis
Building Height: The IL zone has a maximum height of 100-feet.
Staff Comment: The existing emergency communications tower is 150-feet and
exceeds the IL zone’s height limitations. The proposed 25-foot tower extension will
further exceed the IL zone’s 100-foot height limitation. The applicant has requested a
variance to the 100-foot height limitation.
Screening: The City’s surface mounted screening regulation (RMC 4-4-095D) requires
all on-site surface mounted utility equipment shall be screened from public view.
Screening shall consist of equipment cabinets enclosing the utility equipment, solid
fencing or a wall of a height at least as high as the equipment it screens, or a landscaped
visual barrier allowing for reasonable access to equipment. Equipment cabinets,
fencing, and walls shall be made of materials and/or colors compatible with building
materials.
Industrial Zone Exemption: Surface mounted equipment located in industrial
developments that are greater than one hundred feet (100') from residentially zoned
property and/or public streets are exempted from requirements in subsection D1 of
this Section, General Screening.
Staff Comment: The surface mounted emergency communications tower is located
within an industrial zone and greater than 100-feet from residentially zoned property
and public streets and therefore meets the surface mounted equipment exemption.

Report of Hearing Date July 26, 2016 Page 6 of 14
HEX Report_KC PSERN Emergency Comm Tower_16-000418
Landscaping: The City’s landscape regulations (RMC 4-4-070) require a 10-foot
landscape strip along all public street frontages. Additional minimum planting strip
widths between the curb and sidewalk are established according to the street
development standards of RMC 4-6-060. Street trees and, at a minimum, groundcover,
are to be located in this area when present. For industrial zoned lots abutting a
residential zone, a fifteen-foot (15') wide partially sight-obscuring landscaped visual
barrier, or ten-foot (10') wide fully sight-obscuring landscaped visual barrier, is required
along the common property line. Parking lots shall have perimeter and interior lot
landscaping in types and amounts indicated in RMC 4-6-070F.
Staff Comment: No new landscaping is proposed or required as part of this project. The
project site is currently developed with a government facility. The proposed tower
extension does not add gross square footage to the property, or equal 50 percent of the
assessed property valuation, or exceed other applicability thresholds set forth in RMC 4-
4-070B that would otherwise require compliance with the City’s landscaping
regulations.
Tree Retention: The City’s adopted Tree Retention and Land Clearing Regulations
require the retention of 10 percent of trees in an industrial development.
Significant trees shall be retained in the following priority order:
Priority One: Landmark trees; significant trees that form a continuous canopy;
significant trees on slopes greater than twenty percent (20%); Significant trees adjacent
to critical areas and their associated buffers; and Significant trees over sixty feet (60') in
height or greater than eighteen inches ( 18") caliper.
Priority Two: Healthy tree groupings whose associated undergrowth can be preserved;
other significant native evergreen or deciduous trees; and Other significant non- native
trees.
Priority Three: Alders and cottonwoods shall be retained when all other trees have been
evaluated for retention and are not able to be retained, unless the alders and/ or
cottonwoods are used as part of an approved enhancement project within a critical area
or its buffer.
Staff Comment: No clearing or grading, tree/vegetation removal, or new impervious
services are proposed. The scope of improvements is limited to the extension of the
existing emergency communications tower on the King County Office of Emergency
Management building.
Parking: Office uses require a minimum of 2 spaces per 1,000 square feet of net floor
area and a maximum of 4.5 spaces per 1,000 square feet of net floor area. Office use is
a similar use to government facility, which is not identified with specific parking space
requirements set forth in RMC 4-4-080F10d.
Staff Comment: The proposed tower extension does not exceed applicability threshold
criteria listed in RMC 4-4-080B1b and therefore compliance with parking regulations is
not required.
20. Critical Areas: Project sites which contain critical areas are required to comply with the Critical Areas
Regulations (RMC 4-3-050). The proposal is consistent with the Critical Areas Regulations.
Geologically Hazardous Areas: The City’s critical areas map identify slopes on portions
of the project site between 15-40 percent. Several of these areas identified on the map

are within the existing developed area such as the building footprint and parking lot. It
is likely the mapped area is a remnant of the pre-developed site. Other areas mapped
with slopes include peripheral undeveloped portions of the site and areas utilized for
stormwater facilities.
Staff Comment: A geotechnical report (Exhibit 8) prepared for the original site
development identified no landslide, seismic, erosion, or steep slope areas and
prescribed no setback recommendation for the initial development. The proposed
tower extension includes no site work or ground disturbances on the property.
Wellhead Protection Areas: City critical area map identifies a Wellhead Protection
Area Zone 2 on the project site.
Staff Comment: The proposed tower extension does not include the use, production,
storage, treatment, disposal, or management of hazardous materials.
21. Site Plan Review: Pursuant to RMC 4-9-200B2, Site Plan Review is required for all development in the
Employment Area (EA) designation when it is not exempt from Environmental (SEPA) Review. A public
hearing before the Hearing Examiner is required as the proposal meets large project scale criteria of
RMC 4-9-200D2biv. The proposal is a 17-percent increase in height and therefore considered a major
modification requiring a new site plan review application. The proposal is consistent with Site Plan
Review Decision Criteria:
Compliance Site Plan Criteria and Analysis
a. Comprehensive Plan Compliance and consistency.
Staff Comment: See previous discussion under FOF 18, Comprehensive Plan Analysis.
b. Zoning Compliance and Consistency.
Staff Comment: See discussion under FOF 19, Zoning Development Standard
Compliance.
c. Off Site Impacts.
Structures: Restricting overscale structures and overconcentration of development
on a particular portion of the site.
Staff Comment: The existing 150-foot tower is located in the center of a 9.63 acre site
and setback between 241-feet to 461-feet from property lines. The proposal does not
exceed maximum lot coverage or setback requirements. The proposed 25-foot
emergency communication tower extension is approximately a 17 percent increase in
height to the existing tower that does not result in an overscale structure to the existing
development or over concentrate development in a particular portion of the site.
Circulation: Providing desirable transitions and linkages between uses, streets,
walkways and adjacent properties.
Staff Comment: N/A. The proposal is limited to a 25-foot extension to an existing 150-
foot emergency communications tower.
Loading and Storage Areas: Locating, designing and screening storage areas, utilities,
rooftop equipment, loading areas, and refuse and recyclables to minimize views from
surrounding properties.

Staff Comment: See FOF 19, Zoning Development Standard: Screening
Views: Recognizing the public benefit and desirability of maintaining visual
accessibility to attractive natural features.
Staff Comment: Viewshed impacts from residential areas should be minimal as the
location, topography, and existing mature vegetation provides screening of the
existing tower and proposed extension. Photosimulations (Exhibit 6) provided by the
applicant identify view impacts north within the King County and City of Renton
facilities area and to the east within the manufactured home park. Significant
topographic relief and mature vegetation to the south and west indicate limited
viewshed impacts to adjacent areas. The tower extension narrow lattice type
construction is unlikely to alter or obstruct any views, particularly to attractive natural
features such as Mt. Rainier or Lake Washington. Staff recommends as a condition of
approval that the tower be painted a similar color as the existing tower as indicated in
the project narrative and photo simulations. No comments were submitted to the City
concerning views.
Landscaping: Using landscaping to provide transitions between development and
surrounding properties to reduce noise and glare, maintain privacy, and generally
enhance the appearance of the project.
Staff Comment: See discussion under FOF 19, Zoning Development Standard:
Landscaping. The existing mature vegetation and overall landscape width in excess of
100-feet on the north and east property lines in addition to the forested conditions on
vacant county properties and critical area tracts on abutting south and west property
boundaries provide an appropriate transition between the neighboring residential
uses.
Lighting: Designing and/or placing exterior lighting and glazing in order to avoid
excessive brightness or glare to adjacent properties and streets.
Staff Comment: No new lighting is proposed with the tower extension. The existing red
flashing beacon on the tower, which is required by the Federal Aviation Administration,
would be relocated to the top of the extended tower.
d. On Site Impacts.
Structure Placement: Provisions for privacy and noise reduction by building
placement, spacing and orientation.
Staff Comment: The proposed 25-foot emergency communication tower extension will
have no impact on privacy or noise. The construction of the tower is anticipated to
begin one to two months following permit approval. The applicant has stated the
construction will occur during normal work days and work hours. Construction will be
limited to City construction hours of 7:00 am to 8:00 pm Monday through Friday with
hauling hours from 8:30 am to 3:00 pm.
Structure Scale: Consideration of the scale of proposed structures in relation to
natural characteristics, views and vistas, site amenities, sunlight, prevailing winds, and
pedestrian and vehicle needs.
Staff Comment: The existing emergency communication tower is located within an
area of city and county facilities. The location of the tower is setback at distances of
241-feet to the north, 384-feet to the east, 245-feet to the south, and 461-feet to the
west. Viewshed impacts are minimal due to setback, topography and existing mature

Staff Comment: Police and Fire Prevention staff indicated that sufficient resources exist
to furnish services for the proposal. A Fire Impact Fee would not be required for the
proposal.
Parks and Recreation.
Staff Comment: There are no impacts to parks.
Schools.
Staff Comment: There are no impacts to schools.
Water and Sewer.
Staff Comment: N/A. No new water or sewer service is needed for the proposal
Drainage.
Staff Comment: N/A. No drainage improvements are needed for the proposal
Transportation.
Staff Comment: Access to the site is proposed via existing streets. No increase in traffic
is anticipated as a result of the proposal and no transportation impact fee is required.
N/A j. Phasing: The applicant is not requesting any additional phasing.
22. Conditional Use Analysis: The applicant’s request to extend the height of an existing 150-foot
emergency communications tower and additional 25-feet is located in a government facility use within
the IL zoning designation. Pursuant to RMC 4-2-060G, government facilities require a Hearing Examiner
Conditional Use Permit. The proposal is a 17-percent increase in height and therefore requires a new
conditional use permit. The proposal is compliant with the following conditional use criteria, pursuant
to RMC 4-9-030. Therefore, staff recommends approval of the requested Conditional Use Permit.

Compliance Conditional Use Criteria and Analysis
a. Consistency with Plans and Regulations: The proposed use shall be compatible
with the general goals, objectives, policies and standards of the Comprehensive
Plan, the zoning regulations and any other plans, programs, maps or ordinances
of the City of Renton.
Staff Comment: See FOF 18 and FOF 19 for Comprehensive Plan and zoning regulation
compliance, respectively.
b. Appropriate Location: The proposed location shall not result in the detrimental
overconcentration of a particular use within the City or within the immediate
area of the proposed use. The proposed location shall be suited for the proposed
use.
Staff Comment: The applicant contends that the government facility use is already
established on the project site. The applicant’s request is to increase an existing 150-
foot emergency communications tower and additional 25-feet in order to upgrade the
facilities emergency responder system as approved by King County voters. The
proposed extension to the tower will not require a new tower to be constructed. The
emergency communications tower is a component of the King County Office of
Emergency Management and is suited for the use.
Staff concurs with the applicant’s assertion that the proposed location is the
appropriate location for the tower extension. The project site is already serving as the
emergency management office. No new ground disturbances or site work would be
needed to extend the tower.
c. Effect on Adjacent Properties: The proposed use at the proposed location shall
not result in substantial or undue adverse effects on adjacent property.
Staff Comment: The applicant contends that there will be no effect on adjacent
properties as a result of the proposed 25-foot tower extension. The applicant cites
several Bonneville Power Administration towers of similar heights are within the
immediate area of the existing emergency communications tower.
Staff concurs with the applicant’s assertion that no adverse effects will occur on
adjacent properties. Photosimulations provided by the applicant indicate minimal
viewshed impacts and no blockage of view corridors. The existing tower is located
within the center of the 9.63 acre project site and is substantially setback from
property lines. Topography, mature vegetation, and the tower’s location mitigate
adverse effects on adjacent property.
d. Compatibility: The proposed use shall be compatible with the scale and character
of the neighborhood.
Staff Comment: The applicant contends the proposed tower extension is compatible
with the scape and character of the neighborhood. The applicant cites again the
nearby BPA towers of similar height and the proposed extension of only 25-feet.
Additionally, the applicant cites the prominence of surrounding government uses on
the north and west adjacent properties.
Staff concurs with the applicant’s assertion that the use is compatible with scale and
character of the neighborhood. The existing government use is already established
and a 17 percent increase in height would not result in the use becoming
incompatible. Photosimulations indicate minimal viewshed impacts and use of the

23. Variance Analysis: The applicant is requesting a height variance for the 25-foot extension to the existing
150-foot emergency communications tower or a total tower height of 175-feet. Pursuant to RMC 4-2-
130A, Development Standards for Industrial Zoned Property, the maximum height is 100-feet. The
proposal is compliant with the following variance criteria, pursuant to RMC 4-9-250. Therefore, staff
recommends approval of the requested Variance.
project site and abutting properties with City and County facilities is consistent with
the character of the neighborhood.
e. Parking: Adequate parking is, or will be made, available.
Staff Comment: The applicant contends the existing facility has adequate parking and
the proposed extension will not require any additional parking
Staff concurs with the applicant’s assertion that adequate parking is available. The
25-foot increase to the existing emergency communication tower’s height will not
impact the parking demand of the subject site. No evidence of inadequate parking
was identified while reviewing the application.
f. Traffic: The use shall ensure safe movement for vehicles and pedestrians and
shall mitigate potential effects on the surrounding area.
Staff Comment: The applicant contends that no traffic impacts are associated with
these types of facilities as they are unmanned and require infrequent maintenance.
Staff concurs there would be no traffic impacts as a result of the tower extension as
the tower is existing and no new staff would be required due to the increase in height.
The 25-foot increase to the existing emergency communication tower’s height will not
impact vehicle or pedestrian circulation on or around the subject property. No new
vehicle trips are anticipated for the extension and therefore no transportation impact
fee or offsite mitigation is needed.
g. Noise, Light and Glare: Potential noise, light and glare impacts from the proposed
use shall be evaluated and mitigated.
Staff Comment: The applicant contends the proposed tower extension will not create
significant noise, light, or glare impacts. The Federal Aviation Administration will not
require the tower to be lighted beyond the required and existing red flashing beacon
for aircraft warning of an airspace obstruction.
Staff concurs that the 25-foot increase to the existing emergency communication
tower’s height will result in no new noise, light, or glare. To clarify, the existing red
flashing beacon on the tower would be relocated to the top of the tower extension as
required by the Federal Aviation Administration.
h. Landscaping: Landscaping shall be provided in all areas not occupied by buildings,
paving, or critical areas. Additional landscaping may be required to buffer
adjacent properties from potentially adverse effects of the proposed use.
Staff Comment: The applicant contends that no changes are proposed to the
landscaping as the scope of work is limited to the tower extension.
Staff concurs no additional landscaping is needed. The existing government facility
development already contains appropriate landscaping including mature vegetation
in relatively large width along the property lines abutting residential uses.

i. That the applicant suffers practical difficulties and unnecessary hardship and the
variance is necessary because of special circumstances applicable to subject
property, including size, shape, topography, location or surroundings of the
subject property, and the strict application of the Zoning Code is found to deprive
subject property owner of rights and privileges enjoyed by other property owners
in the vicinity and under identical zone classification.
Staff Comment: The applicant contends the current tower height of 150-feet is
ineffective for transmitting and receiving emergency radio communications within the
updated network. The proposed 175-foot height is the minimum tower height needed
to achieve reliable communications.
Staff concurs the applicant suffers practical difficulties and unnecessary hardship. The
existing 150-foot tower does not provide adequate height to transmit emergency
responder signals to the corresponding tower located on Capitol Hill in Seattle. The
applicant is requesting a 25-foot increase to the existing tower for a total of 175-feet,
which is the minimum necessary height for transmission. This special circumstance is
applicable to the topography, location and surroundings of the subject property as it
results in the inability to implement the PSERN voter approved measure to upgrade the
region’s emergency response network. Abutting IL zoned properties provide
governmental facilities management services for City and County operations. The
application of the 100-foot building height limitation deprives the subject property
owner its fundamental duty to implement emergency management for King County.
j. That the granting of the variance will not be materially detrimental to the public
welfare or injurious to the property or improvements in the vicinity and zone in
which subject property is situated.
Staff Comment: The applicant contends the purpose and goal of the regional emergency
communications network is to promote public safety and welfare. An update/expansion
to the current system would further promote public safety and welfare.
Staff concurs that the granting of the variance would not be materially detrimental to
the public welfare or injurious to the property or improvements. The purpose is to
implement a voter approved measure to upgrade emergency responder
communications. The existing tower and its proposed extension is located in the center
of a 9.63 acre site that abuts other governmental facility uses. The existing red flashing
beacon would be relocated to the top of the extended tower for low flying aircraft as
required by the Federal Aviation Administration.
k. That approval shall not constitute a grant of special privilege inconsistent with the
limitation upon uses of other properties in the vicinity and zone in which the subject
property is situated.
Staff Comment: The applicant contends the BPA towers within the vicinity of the subject
property are similar heights to the emergency communication tower and the BPA
towers also provide a service to the public. The IL zone allows government facility uses
and the tower extension is an addition to an existing use.
Staff concurs that a variance approval would not be a grant of special privilege
inconsistent with other uses in the vicinity and zone. King County voters chose to
upgrade the existing emergency response system. The King County Office of Emergency
Management is a permitted and approved use located in the IL zone that provides

communication services to emergency responders. In order for the facility to implement
the PSERN voter measure, the existing 150-foot tower must be extended.
l. That the approval is a minimum variance that will accomplish the desired purpose.
Staff Comment: The applicant contends the 25-foot extension to the existing 150-foot
emergency communication tower is needed to locate three microwave antennas that
connect, as determined by field path analysis, to the towers located on Capitol Hill in
Seattle.
Staff concurs the approval is the minimum needed to accomplish the desired purpose
as stated by the applicant.
