SUBJECT: U.S. WEST Cellular Phone Facility APPEAL
BACKGROUND:
Normed -Shaw Partnership has appealed an approved Conditional Use
Permit (CUP) for a cellular phone facility. The site is located at
13130 44th Avenue South (adjacent to the Highway 599 /133rd Street
interchange). The reason for the appeal is explained in Appendix
B attached.
On September 26, 1991, the Planning Commission conditionally
approved the CUP for a 120 -foot tall cellular phone tower and a
432 - square -foot equipment building with four conditions:
1. That Douglas Fir trees be planted along the perimeter of the
planted area between the St. Johns Wort and seeded grass areas
to create a visual wall of trees;
2. That clusters of Poplar trees be planted on the street side of
the fir trees;
3. That shrub beds be interspersed along the perimeter of trees;
4. That the applicant shall provide a maintenance agreement to
ensure the establishment and survival of all landscape
materials.
The proposal was originally heard by the Planning Commission on
August 22nd. The applicant was asked to return to the Planning
Commission in September with a revised proposal to include
increased setbacks and landscaping (see Attachments F & G). The
conditions of final approval would be reflected in plans submitted
for a building permit.

RE: Letter of Appeal for 91 -3 -CUP: US WEST Cellular Phone Facility
Dear John:
Enclosed is a copy of the letter of appeal from Normed -Shaw
Partnership in reference to the above project approved by the
Tukwila Planning Commission on September 26, 1991.
To assist the City Council in gaining a full understanding of your
request, it is recommended that additional photographs be provided.
The photographs should include a panoramic perspective taken from
the Normed site with a scaled overlay of the cellular phone tower.
The photos should be at least 5" x 7" in size.
A tentative City Council hearing date has been set for November 11,
1991. The photographs should be submitted at least two weeks
prior. You will be notified immediately once the date has been
confirmed:
Feel free to contact me if you have further questions.
Sincerely,

Dear Ms. Cantu,
NORMED -SHAW PARTNERSHIP
OCT - 4 1991
CITY OF TUK9ivtLA
CITY CLERK
Please accept this letter as an appeal of the Planning
Commission Decision to grant a Conditional Use permit (Case
Number 91 -3 -CUP: U.S. West Cellular Tower) to US WEST New
Vector Group, Inc. for the construction of a 120 -foot monopole
cellular phone antenna at 13130 44th Avenue South (adjacent
to the Hwy 599/133rd Street interchange.
Currently we own the property directly across the street from
the proposed tower. We also own six+ (6 +) acres a short block
away, which is "home" to our wholesale distribution business
and the planned development of other high - quality office/
warehouse buildings.
When we originally constructed our current facilities, we were
encouraged by the City of Tukwila, and particularly the
Department of Community Development, to build a quality
building as this was a "high visibility area ". At that time
we were assured all future development would be continued at
a high level of appearance and quality.
This particular location is a key gateway to and from
Interstate 5 and State Route 599. It therefore has a high
degree of visibility and creates an important first impression
for people exiting these thoroughfares into Tukwila. A tower
at this location would significantly detract from what is
otherwise becoming an excellent first impression and
especially so as the surrounding properties upgrade in
quality.

This tower is 120 feet tall which will certainly be a very
visible and obtrusive landmark.
It would also appear that such a tower, if located on a higher
elevation, would not require a height of 120 feet and would
be less obtrusive.
We strongly urge the City Council to reconsider the granting
of this Conditional Use Permit and encourage the applicant to
find a more Suitable location for this tower.

AUGUST 22, 1991 MEETING. MR. GOMEZ SECONDED THE MOTION; MOTION
PASSED UNANIMOUSLY.
Denni Shefrin presented the staff report. She stated that this was a continuation from the
August 22, 1991 hearing. The applicant is proposing a 120 foot tall cellular tower, as well
as an equipment building. One of the issues from the August 22nd hearing was how to
mitigate the visual impacts from the adjacent properties. The applicant has re- submitted the
APPENDIX C
Planning Commission Minutes Page 2

site plan with a revised landscape plan and cross sections in an attempt to address those
concerns. The changes include increased setbacks by approximately 93 feet. Also, the
applicant is proposing to use the entire area between the property line and the existing
building for landscaping improvements. The proposal also includes increased landscape
area, and an increase in the number of trees and shrubs. Staff stated that in reviewing this
application, the Planning Commission should consider two things: 1) does the proposal
comply with the criteria of a Conditional Use Permit and 2) if they decided that this is an
appropriate site for this type of facility, are their concerns adequately addressed? The
Planning Department did discuss with the applicant additional modifications that could be
considered to enhance the site and increase visual buffers between the adjacent properties
and the facility.
Mr. Malina asked if there was a maintenance agreement proposed.
Staff stated that the applicant would be better able to address that issue.
John Hunt, 1218 3rd Ave., Seattle, WA:
He stated that the changes in the landscaping plan were made on the general direction given
by the Commission members at the last meeting with some assistance from staff. He stated
that certain types of maintenance, and irrigation would depend on what is decided as far as
the actual design. He stated that U.S. West would commit to any maintenance agreement
that the City thought would be appropriate and necessary to keep the site in the condition
which would be approved.
Mr. Malina asked if there currently was a maintenance crew which visited their existing sites
on a regular basis.
Mr. Hunt said that they had a inspector for each system who comes out once or twice a
month to verify if anything needs to be done. Most of the sites do not have nearly this much
landscaping; most of the sites are only 60 square feet.
Mr. Malina asked how many of the existing sites have an irrigation system installed.
Mr. Hunt said that he could not answer that because he is only a consultant to U.S. West,
and has not visited all of their sites.
Rich Ward, 1906 E. Aloha, Seattle; landscape architect:
He stated that the revised landscape plans speak for themselves and he would answer any
questions of the Planning Commission.
Mr. Flesher asked what maintenance would be required with the landscaping that they are
proposing.
Planning Commission Minutes Page 3
September 26, 1991
Mr. Ward said the maintenance of the site would be a minimum of once a month for
mowing, weeding, leaf collection, mulching and checking of the irrigation system. Since the
area around the site belongs to the Department of Transportation, to have a manicured lawn
on the site may not be the proper way to handle this project.
Mr. Malina asked if that would be his recommendation to U.S. West.
Mr. Ward said that he would recommend that.
Mr. Malina asked if he was aware if U.S. West had a maintenance program in place in
which each site is visited on a timely schedule.
Mr. Ward stated that he thought that every site was visited at least once a month, but did
not know if they had a landscape crew.
Mr. Hunt stated that there is a site supervisor who checks each site. In this case, it would
be easy to add a landscaping check on any site which has substantial landscaping. He went
on to say that because there aren't that many sites that have extensive landscaping, it's
probably more appropriate to contract out certain types of maintenance because they don't
have enough for a full crew.
Mr. Flesher closed the public hearing at 8:20 p.m.
Mr. Haggerton asked staff how tall the metal light standards are in the City.
Staff stated approximately 35-40 feet.
Mr. Haggerton said that he would not . make a motion because he felt the proposed tower
is too tall for that particular area. He went on to say that in his opinion, it was too .
domineering for this gateway entrance into Tukwila.
Mr. Flesher re- opened the public hearing at 8:25 p.m.
Mr. Haggerton asked the applicant if U.S. West had . done an adequate job of finding a
location or if there isn't another location they might consider?
Mr. Hunt stated that the entire gateway area was searched and no -one was found in that
area who was willing to lease to U.S. West. It would take 4.6 months to go through a new
FAA filing before they could file for a site other than this site. If a site was selected west
of this one, the height would have to be increased, in order to provide for coverage up the
hill. He went on to say that U.S. West was unaware that this was a gateway area until two
months into the

Staff added that this project was also delayed because of the Sensitive Areas Moratorium
and staff could not proceed with the application until the moratorium was removed.
MR. MALINA MOVED TO APPROVE PROJECT 91-3-CUP: U.S. WEST NEW VECTOR

MAINTENANCE PLAN BE PUT IN PLACE. MR. FLESHER SECONDED THE
MOTION; MOTION PASSED BY= A VOTE :OF3 =2, WITH MESSRS. HAGGERTON AND
GOMEZ OPPOSED.
Darren Wilson presented the staff . report. Staff stated that the applicant for this project,
Gencor, is requesting a rezone from. P.O. (Professional Office), to C -1 (Neighborhood
Retail). The site is located at 5900 Southcenter Blvd. (North Hills Office /Gencor
Development). The Comprehensive Plan designation for this area is commercial and the
existing zoning is P.O. There was a Mitigated Determination of Non - Significance issued in
October 1990.
Approximately a year ago the Planning Commission recommended approval of the rezone,
however, the City Council denied the rezone due to the traffic analysis. The applicant has •
come back and submitted additional information pertaining to the traffic analysis and the
concerns of the City Council. Staff stated that the rezone complies with the Comprehensive
Land Use Policy Plan, in addition, the rezone is not considered to be detrimental to the
public welfare.: This site received Board of Architectural Review site plan approval in July
of 1990 and the plan will comply with the C -1 zoning designation. Through the
Environmental Review process, there were no significant impacts that were identified,
however, it is a steep site. The Council approved the waiver from the Sensitive Areas
Ordinance to process the SEPA determination. The applicant has provided additional
landscaping, as well as a geo- technical soils report that exceed the SAO requirements as they
are today. Ron Cameron, City of Tukwila Engineer, has provided a letter which indicates
that the rezone will not have any measurable effects on traffic. This rezone would not
create spot zoning.
This site is unique in that to the 'north is a steep slope, but is buffered by the multi- family
development, to the east is landscaping which serves as a buffer between the existing office
building, and to the west are commercial uses. With regard to the requirement differences
between P.O. and C -1, the height requirements in P.O. are the same as that required in C-
1; the landscaping requirements in P.O. exceed that required in C -1, the applicant has

Continued from August 22, 1991 hearing
U.S. WEST New Vector Group, Inc. proposes to erect a 120 -
foot tall monopole cellular phone antenna and construct
a 423 - square -foot equipment building.
13130 44th Avenue South (Adjacent to the Hwy 599/133rd
Street Interchange)
22nd, The Planning Commission moved to continue the above
allow the applicant to modify the site design. The
Commission raised the following concerns regarding the
1) Because the site is located within a high visibility area, the
setback from the southwest corner of the site for both the
equipment building and monopole should be increased;
2) Visual screening of the facility should be adequate to
mitigate visual impacts to adjacent streets and properties.
Based on the above issues, the Planning Commission moved to
continue the public hearing to allow the applicant to modify the
site design.
In response to items cne and two above, the applicant has made the
following revisions (see attachments F and G):
1. The setback for the equipment building from the southeast
property line has been increased from 20 feet to 60 feet;
5. Materials for both the retaining wall and equipment building
have not changed from the original concept.
6. Landscape materials would include two types of groundcover,
three types of shrubs, and two types of trees including Poplar
and Douglas Fir.
In reviewing the proposal, the Planning Commission should consider
the following two issues:
1. Given the changes now proposed by the applicant, do the
revisions comply with the Conditional Use Criteria for the
approval of a 120 -foot tall cellular phone tower at this
location?
2. And if this location is deemed appropriate for the facility,
would the changes as proposed address the concerns raised?
If the Planning Commission feels the site is appropriate for the
cellular phone facility, the Planning staff recommends additional
landscaping be incorporated into the site plan revisions to create
a more dense visual screen of the facility.
The following is recommended:
1. Plant Douglas Firs along the permimeter of the planted area
between the St. Johns Wort and seeded grass (see attachment
F);
2. Plant clusters of Poplars along the outside the line of fir
trees;
3. Shrub beds could be interspersed along the perimeter of the
trees.

Staff Report to the 91 -3 -CUP: U.W. West New Vector
Planning Commission Page 2
Project Description: The proposal includes the construction of a 423 - square foot, 10
feet 7 -inch high pre- fabricated equipment building and a 120 - foot -tall cellular phone
monopole on the southwest portion of an approximately .50 acre site. The monopole
would carry 9 cellular phone base station antennas. The facility would be enclosed
on the east and north sides by a 6- foot -high chain -link security fence.
Existing and Surrounding Land Use: The corner site is relatively flat and is occupied
by an existing industrial /storage building. The property is accessed by 132nd St.
(Valley St.) which is currently unpaved. Land uses which are in the immediate
vicinity are predominately light industrial and warehouses. Adjacent land uses
include:
North: industrial /storage building/contractor's office
South: Hwy 599 interchange
East: Hwy 599 interchange
West: Single family residence
Terrain: The portion of the site proposed for the use is vacant and has a gravel
surface with tall grasses along the south and east property lines. A 6 -foot high chain
link fence runs along the south and east property lines.
The applicant proposes to erect a 432 - square -foot equipment building and a 120 -foot
high cellular monopole to carry 9 cellular phone base station antennas.
The building will contain low -power FM -band radios (800 -900 MHz bands at 100
watts output from antenna) and computers to control channel usage for mobile or
portable phones in the immediate area (1 -2 mile radius). The equipment building
will contain back -up batteries for short power outages in the main room and a diesel
generator for extended power outage use in a separate chamber at the end of the
building. Diesel fuel (155 gallons) will be stored in an isolated chamber with "spill -
pan" floor to contain all liquids within building.
The Conditional Use Criteria are shown below in bold print followed by the
applicant's and staffs response.
91 -3 -CUP: U.W. West New Vector
Staff Report to the
Planning Commission
18.64.050: General Review Criteria.
Page 3
(A) The proposed use will not be materially detrimental to the public welfare or injurious to the
property or improvements in the vicinity of the proposed use or in the district in which the subject
property is situated;
Applicant's Response
"The operation will create very little traffic (1 visit per month by technician plus any
repair visits). Noise will be less than the ambient highway noise. No processes will
create impacts off -site or hazardous emissions or spills. Radio frequencies and signal
strength will not interfere with other electronic processor equipment in the industrial
area, nor create any health risks for persons living or working in the area.
Staff's Response
The site is located in an industrial zone surrounded by a highway, industrial and
warehouse uses except for an isolated single -family residence. The cellular phone
monopole and building would be placed close to adjacent streets and away from the
nearby building.
Cellular radio power density levels are regulated by the government as a potential
environmental concern. The very low power levels and ultra high frequencies at
which the cell site transmissions occur demand periods only (weekday commuting
hours) according to the applicant.
(B) The proposed use shall meet or exceed the performance standards that are required in the district
it will occupy;
Applicant's Response
"Applicant will discuss structure colors and site screening with City staff and will
follow specifications recommended by staff and agreed to by BAR."
Staff's Response
The M -1 zone requires 15 feet of landscaping in the front and no landscaping
adjacent to the sides and rear property lines. The zone allows a building height of
4 stories or 45 feet.
The site is currently improved with a 4,100- square -foot industrial building. There is
currently no landscaping on the property except for tall grasses along the south and
east property lines.
Staff Report to the 91 -3 -CUP: U.W. West New. Vector
Planning Commission Page 4
The applicant proposes a 15 to 25 -foot wide landscaped area along the south and
along half the length of the east property line.
The equipment building would be 12 -feet 7- inches high.
(C) The proposed development shall be compatible generally with the surrounding land uses in terms of traffic
and pedestrian circulation, building and site design.
Applicant's Response
Extremely low traffic would be expected and would not generate or impede
pedestrian traffic. Building and site design will be of higher quality than existing
adjacent development.
Staff's Response
Applicant's Response
There would be very little vehicular or pedestrian traffic associated with this project.
Large box -type warehouse buildings dominate the vicinity. The design and exterior
materials of the equipment building were selected to blend with the natural setting
being created as a "gateway" and to soften the overall appearance of the facility.
(D) The proposed use shall be in keeping with the goals and policies of the Comprehensive Land Use Policy
Plan.
The site is in a manufacturing area where existing and future land uses are least likely
to conflict with it (no consistent, existing pattern). The site uses a remote property
remnant on a highway interchange, generally unsuited to and therefore not affecting
or displacing other manufacturing uses. The use is located in an area where the view
form the surrounding residential areas (hillside to west) already includes similar, pole -
type visual elements.
Staff's Response
There are no specific policies contained within the City's Comprehensive Policy Plan
which address this type of utility, however, Goal 3 of the Transportation/Utilities
section states the following: "Assure a public service level consistent with the needs
and desires of the community." (Page 19)
Several factors determine the siting of cellular phone facilities to ensure quality
service:
Staff Report to the 91 -3 -CUP: U.W. West New Vector
Planning Commission Page 5
1. topographic constraints such as hillsides
2. heights of surrounding structures
3. ability to maintain a direct line of site with other cellular phone facilities.
The table below lists approved facilities (Nos. 1 and 2) and proposed (Nos. 3 thru 5).
Location Height of Pole w /antenna
1) 12228 51st Place South 100 feet
2) NE corner of S 158th St. 115 feet
(Longacres Way) and
Nelson Place.
3) 15426 35 Ave. S. 60 feet
4) 566B Industry Drive 78 feet
5) 13130 44th Ave S. 120 feet
By permitting fewer cellular facilities at key locations may reduce the need for
additional cell sites throughout the City, and thus, reduce negative cumulative visual
impacts.
(E) All measures have been taken to minimize the possible adverse impacts which the proposed use may have
on the area in which it is located.
Applicant's Response
"See siting factors noted above; the pole height is the minimum necessary to serve
the local area with this utility service from a single site, without proliferation of such
sites in the same geographic area and visual area."
Staff's Response
Because of the site's topography, any structure erected on the property would be
difficult to screen. The property is at a lower elevation than the surrounding
properties and is visible from the highway and from both directions on 133rd Street.
The proximity of the site to the interchange provides an opportunity to create a
gateway effect into the City of Tukwila. For this reason, staff has requested the
Staff Report to the 91 -3 -CUP: U.W. West New Vector
Planning Commission Page 6
applicant incorporate into the overall design, elements which would help to identify
the area as a gateway.
The following features would be incorporated into the project to achieve two goals:
Goals.
1. create a gateway into the City
2. soften the visual impact of the cellular phone facility from adjacent streets and
properties.
Features.
1. The exterior of the equipment building would be of naturally - stained wood siding
with a metal mansard roof
2. A masonry retaining wall would wrap around the south and east sides of the
building
3. A 5 -foot high landscape berm would be placed along the south and a portion of
the east property line (within the Hwy 599 public right -of -way)
4. Landscape materials consisting of Poplar and Douglas Fir trees, deciduous and
evergreen shrubs and ivy would be planted along the south and east portions of the
site property lines atop the berm.
When landscaping is used to give identity to an area, similar materials are common
in order to create a focal axis into or through an area. Poplar trees were specifically
chosen because they exist on the site south of the on -ramp. Also the vertical growth
of Poplars would help to soften the impact of the monopole.
In addition, the monopole would be painted sky -grey to blend with the typical year -
round sky color.
CONCLUSIONS
1. Due to the location and type of use proposed, the use would not be materially
detrimental to the public welfare or injurious to the property or improvements in the
vicinity.
2. Because of the location of the structure relative to the site, surrounding buildings and
surrounding land uses and proposed color, the monopole would not create an adverse
visual impact to the area.
3. The siting of the structure would not impede vehicular or pedestrian movement.

Since no specific policy currently exists that addresses the specific request, the request
for a Conditional Use Permit would not adversely affect the implementation of the
Comprehensive Land Use Policy Plan.
The applicant has addressed all measures in minimizing any adverse impacts for this
area. Proposed landscaping would be in accordance with Attachment B. The
monopole would be painted grey to blend with the sky. The equipment building
would be a natural - stained wood siding with a mansard roof. The retaining wall
would be masonry.
T e Planning Division recommends approval with the following conditions:
1. Attachment 'B' calls out possible U.S.West signage with the proposed retaining wall
(east elevatioin). All signage must be reviewed and approved by the Planning
Division prior to issance of sign permits. Signage should be designed in a manner
which enhances the overall project.
As noted in the report, a color sample for the monopole has not yet been provided.
The applicant shall submit to the Planning Division a color sample prior to the
issuance of Building Permits.

I am enclosing supplemental materials to assist you in the preparation of the staff report for
the above applications. These include:
(1) Photo - composites made up of photos of an existing NewVector "monopole" of similar size,
taken at measured distances, mounted on background 'photos of the Riverton site taken at the
same estimated distances, at various points around the vicinity. The Andover pole will not
be visible for its full height iron most areas, so no photo-composite was made; the
architectural elevation should adequately illustrate the scale.
(2) A basic landscaping plan for the Riverton site, sent under separate cover by the architect;
we would expect to use this as a starting point for discussion with Planning staff of the best
landscaping to meet the City's objectives in this area. No landscaping plan is submitted for
the Andover site, as it is surrounded by paved parking and loading area. A solid fencing
screen could b^ used if appropriate, but landscaping would be difficult to install (see photos).
(3) Description • f the need for the facilities, based on NewVector's system design and need
for capacity e: :mnsion (following discussion).
I hope that these will be helpful, and that you will feel free to call me if you need any materials
further explained or supplemented.
THE SYSTEM DESIGN:
Cellular phone service is provided in "cells ", which are geographic service areas defined by
local topography as reachable from a single "cell site" with line -of -sight transmission from the cell
site's antennas. The system uses low - power FM radios to broadcast in allocated frequencies in the .
upper end of the UHF hand. Where a market has a potential for a large volume of simultaneous calls
on portable or mobile telephones;' which may exceed the number of frequencies allocated to the
company, multiple cells are set up at low -lying locations. These use topography to isolate the next -
adjacent cells from one another, so that allocated frequencies can be re -used without interference
with phones using the same channel some distance away.
The Tukwila area has up to now been served by a single cell site, an antenna next to the
water tower at the top of the hill west of Southcenter (3765 S. 164th St.), now in the City of SeaTac.
This cell is currently being overloaded by call volume from the ScaTac Airport area, combined with
the high volume from the 1 -511 -405 interchange area. Capacity needs to be increased by "subdividing"
the single cell serving Tukwila, SeaTac and Burien into a number of smaller cells. These are what
may be called "second generation" cell sites which, instead of a covering a broad area from a hilltop
tower, are focussed at small, local areas from a shorter pole set in a geographic basin, using the edges
of the basin to help limit signal carry to a defined area.

CITY OF TUKWILA
PLANNING DEPT.
Both the Riverton and Andover sites are a part of a general plan for subdivision of the former
"Tukwila" cell; the existing Tukwila cell will be relieved of call volume in the Green and Duwamish
Valley areas to the East of it, by these two proposed sites, and on the south and west peripheral
service areas by new cells in Burien and Des Moines. The "Tukwila" cell site will then be turned
down in power and made directional, to only serve the SeaTac area. Topographic breaks between
most of these cells, the natural ridges, will be used to isolate signals and allow channel re -use; this
will be illustrated at the hearing with graphics and maps.
In answer to your question whether further cell sites are contemplated in Tukwila, the answer
would be a tentative "no ", for the "second generation" sites. Mere may be some poor signal areas
evident, once these new sites are on the air, which might require supplementation, possibly with a
passive repeater or a small cell. An example might be Interurban Avenue, where it passes close to
the hill north of City Hall; if the reduction of power at other sites deprives it of a strong signal, there
might be a need to 1111 in from another location. Beyond this type of second generation design fine -
tuning, new cells might be held off until 'Tukwila might generate sufficiently dense call traffic to go
to a "third generation design ", such as is now being installed in downtown Seattle and Bellevue.
Third generation sites tend to be quite low, such that virtually all are mounted on building rooftops,
with equipment typically in the building.
RADIO SIGNALS AND HEALTH ISSUES:
The issue of potential health impacts of radio broadcast signals has arisen in a number of local
communities, generally accompanied by considerable confusion between different types of electro-
magnetic fields (EMF) and different frequencies of broadcasting and signal modulation. Literature
cited by concerned citizens generally focusses on two types of field or radio signal: major facilities
such as radar insta!!ations or major microwave relay points, or high-voltage electrical transmission
liftes and other sources of EvIi which are modulated at an extremely low frequency (ELF).
There is also, understandably, confusion between discussions of "EMF" and "ELF".
Documented reasons for concern in these areas, plus misunderstanding of the term "microwave ",
occasionally spills over as concern for all manner of Radio- frequency (RF) signals, most of which do
not in fact have the characteristics of the sources of concern. Cellular radio, especially, is in a range
of frequencies (formerly the upper end of the "Ui•IF' television band) which is a million to ten million
times greater frequency than the area of concern for "ELF" health effects. In terms of the concern
for very powerful radio -band generated EMF, the cell sites generate a max imum power which is lower
by a factor of one millionth, compared to the military radar installations which are indicated as a
concern. Power density is similar to that produced from the antenna of a single "Han" radio
operator, who can broadcast at 1000 to 4000 watts "ERN" (effective radiated power, from antennas).
Finally, though cellular is in the upper end of the "UHF" spectrum, close to the arbitrary
boundary with "microwave" (one Gigal•lertz and above), there is not the potential for tissue damage
from induced heating, which occurs with special frequencies tuned to the resonant frequencies of
tissue molecules or (as in a microwave oven) the water molecule. Some tissue heating or other
biological effects are a potential which has not been experimentally ruled out entirely, so the industry
does maintain standards for maximum EMF strength for general safety. The closest comparison is
with the major television antennae, which have been broadcasting in heavily populated areas for 40-
50 years, at similar frequencies but at power densities 100 to 1000 times greater than cellular phone
antenna sites, without epidemiological indications of potential health effects.
Volumes of technical studies and reports in these areas have been reviewed jointly over the
past two years by the City of Seattle and by King County, assisted by technical staff in the Seattle -
King County Health l)eparunent. Conclusions, embodied in draft ordinances now up for adoption,
include setting maximum levels for electro- ragnetic field strength in the U1 -IF frequencies of 200
microwatts per square centimeter; these are 10 tunes to 100 times greater than the levels which this

type of cell site will generate at or near the base of the pole. Detailed calculations and comparisons
can be provided if desired. Should the City desire to check these general conclusions independently,
1 would recoinniend that you call Mr. Kurt Horner at the Seattle -King County Health Department,
at 296 -4974.
CELL SITE DESIGN:
As noted elsewhere, the Riverton cell site search area was restricted to the center of the
natural bowl at the south end of the Duwamish Valley. Ideal sites were within the Gateway area,
though this area has generally developed as a .high - quality office /industrial park and had no
landowners willing to accommodate a cell site. Sites on the periphery were investigated, and this site
was chosen, utilizing a small property corner close to SR -99. There are a number of tall poles in the
vicinity, including gas station signs and interchange light poles. The equipment building will be
screened by low -level landscaping and fencing; the pole will to some extent be screened by existing
trees, but more by the substantial distance between the site and the nearest residential zones on the
hillsides to the West and South.
The Andover site is in the middle of a developed industrial area, behind a building and facing
a railroad spur and loading docks. The pole top will be visible within the industrial area but distance
will diminish the scale of the pole from outside the industrial zones. The search area for the site was
almost entirely within the East Andover industrial Park, where the hill north of City Hall blocks signal
transmission between it and the Riverton site, yet a good transition between the two signals can be
made along the crest of I -5 north of the 1 -405 interchange.
1 encourage follow -up questions and discussion of these materials. I would be happy to
supplement them if needed for the staff report or at the public hearings. A joint hearing date on the
two sites will facilitate the explanation of the cellular system design and how it has resulted in the
location and characteristics of these two proposed sites.

RIVERTON CELL SITE
SUPPORTING STATEMENT FOR 120' TOWER
Cellular sites are designed to contain radio frequency (RF)
signals to specific geographical regions. Terrain (earth) is the
most effective obstacle next to trees and buildings to contain RF.
Proper design allows the reuse of frequencies in another
geographical area in the same metropolitan region without
interference (crosstalk, dropped calls, etc.). Achieving this
requires careful site location, antenna height above ground and
antenna type. But, with reuse, more calls can be placed
simultaneously than there are frequencies available.
The Riverton cell site is placed to contain signals to an area
approximately 2 miles in radius. In addition to being contained,
signals from a cell must also propagate (travel) far enough to link
up (overlap) with signals from neighboring cell sites. Precluding
this, calls would become very noisy and possibly drop before
handing off to the neighboring cell as the phone drove away from
the initial cell.
The 120' antenna height is required specifically for overlap
to two neighboring cell sites. One is a proposed site in BurienU)
the other is an existing site in McMicken Heights() I have attached
a map inidicating the locations of all three cells. The solid red,
blue and black lines are contours of equal signal from each of the
three sites. These lines were obtained through actual field
measurements. Each line indicates approximately where signal
levels were measured to be -75dBm to -80dBm (a smaller negative
number indicates a stronger signal). This is the level we desire
to have calls handoff. If this level were lower, say - 85dBm, then
the call would become noisy before handing off to a stronger
signal. As the drawing shows the 75 -80dBm contours for Burien
(red) and Riverton (black) do not overlap completely, thus handoffs
from Riverton to Burien or v.v. will experience slight degradation
in the shaded, area. Without testing a 100' height at Riverton I
determined that that height was not useable due to the marginal
signals measured at 120'. Usually sites located close to the base
of a hill (such as this) require a higher tower to cover the top of
the hill vs. a tower farther away from the base of the hill.
Finally, containing signal from such a high height will be
realized through the selective use of antennas. Coverage of the
hill towards Burien will use a small, very directional antenna
aimed towards the shaded area. Additional antennas will be
installed at a lower height to cover north and east. The lower
height will make up for the lack of sufficient terrain to obstruct
the signal from traveling too far to the north and east. As these
antennas are lower their signals will be more obstructed by trees
and buildings. Therefore, it is necessary to radiate additional
power, possible only__ _with. .the __use_. of higher gain antennas.
Unfortunately, the h gher'the!,ga1i j; gbe l *nger the antenna, thus the
8' length.

Dear Ms. Shefrin,
I recently received the Public Hearing Notice announcing the
Planning Commission Public meeting scheduled for August 22,
1991. I would like to take this opportunity to voice my
opposition to the application for a Conditional Use permit
(Case Number 91 -3 -CUP: U.S. West Cellular Tower) submitted by
US WEST New Vector Group, Inc.
Currently we own the property directly across the street from
the proposed tower. We also own six+ (6 +) acres a short block
away, which is "home" to our wholesale distribution business
and the planned development of other high quality
office /warehouse building.
When we originally constructed our current facilities, we were
encouraged by the City of Tukwila, and particularly the
Department of Community Development, to build a quality
building as this was a "high visibility area ". At that time
we were assured all future development would be continued at
a high level of appearance and quality.
This particular location is a key gateway to and from
Interstate 5 and State Route 599. It therefore has a high
degree of visibility and creates an important first impression
for people exiting these thoroughfares into Tukwila. Not
only would a tower at this location be cosmetically
unattractive (actually downright ugly is the adjective that
comes to mind), with the close proximity to these major
interchanges, it is also a potential traffic hazard.

Please also consider there are streams located directly across
the street, as well as on our property, which have been
designated a "Sensitive" by the City of Tukwila. We cannot
help but question the desirability of locating a 120' tower
in such an area.
It would also appear that such a tower, if located on a higher
elevation, would not require a height of 120' and would be
less obtrusive.
We strongly recommend that the Planning Commission encourage
the applicant to find a more suitable location for this tower.

I hope these serve to answer your questions regarding the height of the two proposed towers.
The map which I showed you indicates the slight signal overlap which is necessary at the boundary
of the broadcast areas or "cells '. These allow a smooth "handoff' from one antenna to the next, on
a mobile r all, i.e., just as the call quality or clarity starts to degrade below an acceptable level, the
mobile p' one begins to pick up rising signal strength from the next cell antenna, and Is automatically
"hander •off" to the stronger, clearer signal by the monitoring computer. Insufficient overlap on the
comps' ar plot or drive -test plots, based on equal contours of signal strength, means that the call
clari ?, could degrade to where it would be difficult to understand, or the connection could be broken,
befr,e the handoff occurred.
CellOne (McCaw system) has two towers recently approved at 100' height each, in the same
tV J areas of Tukwila (Green River Basin and Duwamish Basin). These were presumably justified to
City of Tukwila on the same standard, i.e., needing the height so that there was some acceptable
• gnat overlap at the tops of the intervening ridges between the two basins, including the hill behind
Ity Hall and the ridges east and west of it.
Because of the discussions with City staff in late 1990 and early 1991, U S WEST lost
o ,portunities to locate the Riverton (Duwamish Basin) antenna towards the center or easterly side of
tile basin, where CellOne is located. The current application was as close to the "height exception
zone" as possible, but was still about 1/2 mile closer to the western ridge. This gives a steeper rising
angle between the site and the shoulder of the ridge to the West, which means that a somewhat taller
antenna would be needed to cover the Military Road corridor on the ridge shoulder, not reachable
from the next antenna to the West (Burien). This tower therefore had to be set higher than CellOne's
approved design. U S WEST's engineers estimated 150' as desirable, from computer simulation.
However,. anticipating City concern on the height, I requested that they do an actual drive -test, with
a radio raised on a boom truck. This test, summarized in the map and narrative from the project
- engineer (forwarded to you earlier) confirmed the minimum height could be 120' rather than 150'.
The Riverton antenna height was critical; once it was set, the Andover antenna height could
be set to match it with minimum overlap. This could be achieved with a 75' tower, 25' lower than
CeltOne's nearby tower at 100'. It seems reasonable that an equivalent signal . overlap will be
achieved by the two tower pairs: CellOne's two towers already approved at 100' and 100', and U S
WEST's two applications at 120' and 75'. Please call me at 947 - 0640 on Thursday or Friday if you
have any further questions.

CITY OF TUKWILA
PLANNING DEPT.
Both the Riverton and Andover sites are a part of a general plan for subdivision of the former
"Tukwila" cell; the existing Tukwila cell will be relieved of call volume in the Green and Duwamish
Valley areas to the East of it, by these two proposed sites, and on the south and west peripheral
service areas by new cells in Burien and Des Moines. The "Tukwila" cell site will then be turned
down in power and made directional, to only serve the SeaTac area. Topographic breaks between
most of these cells, the natural ridges, will be used to isolate signals and allow channel re -use; this
will be illustrated at the hearing with graphics and maps.
In answer to your question whether further cell sites are contemplated in Tukwila, the answer
would be a tentative "no ", for the "second generation" sites. There may be some poor signal areas
evident, once these new sites are on the air, which might require supplementation, possibly with a
passive repeater or a small cell. An example might be Interurban Avenue, where it passes close to
the hill north of City Hall; if the reduction of power at other sites deprives it of a strong signal, there
might be a need to fill in from another location. Beyond this type of second generation design fine -
tuning, new cells might be held off until Tukwila might generate sufficiently dense call traffic to go
to a "third generation design ", such as is now being installed in downtown Seattle and Bellevue.
Third generation sites tend to be quite low, such that virtually all are mounted on building rooftops,
with equipment typically in the building.
RADIO SIGNALS AND HEALTH ISSUES:
The issue of potential health impacts of radio broadcast signals has arisen in a number of local
communities, generally accompanied by considerable confusion between different types of electro-
magnetic fields (EMF) and different frequencies of broadcasting and signal modulation. Literature
cited by concerned citizens generally focusses on two types of field or radio signal: major facilities
such as radar installations or major microwave relay points, or high - voltage electrical transmission
lines and other sources of EMF which are modulated at an extremely low frequency (ELF).
There is also, understandably, confusion between discussions of "EMF" and "ELF ".
Documented reasons for concern in these areas, plus misunderstanding of the term "microwave ",
occasionally spills over as concern for all manner of Radio- frequency (RF) signals, most of which do
not in fact have the characteristics of the sources of concern. Cellular radio, especially, is in a range
of frequencies (formerly the upper end of the "UHF" television band) which is a million to ten million
times greater frequency than the area of concern for "ELF" health effects. In terns of the concern
for very powerful radio -band generated EMF, the cell sites generate a maximum power which is lower
by a factor of one millionth, compared to the military radar installations which are Indicated as a
concern. Power density is similar to that produced from the antenna of a single "Ham" radio
operator, who can broadcast at 1000 to 4000 watts "ERP" (effective radiated power, from antennas).
Finally, though cellular is in the upper end of the "UHF" spectrum, close to the arbitrary
boundary with "microwave" (one Gigal-lertz and above), there is not the potential for tissue damage
from induced heating, which occurs with special frequencies tuned to the resonant frequencies of
tissue molecules or (as in a microwave oven) the water molecule. Some tissue heating or other
biological effects are a potential which has not been experimentally ruled out entirely, so the industry
does maintain standards for maximum EMF strength for general safety. The closest comparison is
with the major television antennae, which have been broadcasting in heavily populated areas for 40-
50 years, at similar frequencies but at power densities 100 to 1000 times greater than cellular phone
antenna sites, without epidemiological Indications of potential health effects.
Volumes of technical studies and reports in these areas have been reviewed jointly over the
past two years by the City of Seattle and by King County, assisted by technical staff in the Seattle -
King County Health Department. Conclusions, embodied in draft ordinances now up for adoption,
include setting maximum levels for electro-magnetic field strength in the UHF frequencies of 200
microwatts per square centimeter; these are 10 times to 100 times greater than the levels which this

CELL SITE DESIGN:
As noted elsewhere, the Riverton cell site search area was restricted to the center of the
natural bowl at the south end of the Duwamish Valley. Ideal sites were within the Gateway area,
though this area has generally developed as a high- quality office/industrial park and had no
landowners willing to accommodate a cell site. Sites on the periphery were investigated, and this site
was chosen, utilizing a small property corner close to SR-99. There are a number of tall poles in the
vicinity, including gas station signs and interchange light poles. The equipment building will be
screened by low -level landscaping and fencing; the pole will to some extent be screened by existing
trees, but more by the substantial distance between the site and the nearest residential zones on the
hillsides to the West and South.
The Andover site is in the middle of a developed industrial area, behind a building and facing
a railroad spur and loading docks. The pole top will be visible within the industrial area but distance
will diminish the scale of the pole from outside the industrial zones. The search area for the site was
almost entirely within the East Andover Industrial Park, where the hill north of City Hall blocks signal
transmission between it and the Riverton site, yet a good transition between the two signals can be
made along the crest of I -5 north of the I -405 interchange.
I encourage follow -up questions and discussion of these materials. I would be happy to
supplement them if needed for the staff report or at the public hearings. A joint hearing date on the .
two sites will facilitate the explanation of the cellular system design and how it has resulted in the
location and characteristics of these two proposed sites.
type of cell site will generate at or near the base of the pole. Detailed calculations and comparisons
can be provided If desired. Should the City desire to check these general conclusions independently,
I would .recommend that you call Mr. Kurt Homer at the Seattle -King County Health Department,
at 296 -4974.

RIVERTON CELL SITE
SUPPORTING STATEMENT FOR 120' TOWER
Cellular sites are designed to contain radio frequency (RF)
signals to specific geographical regions. Terrain (earth) is the
most effective obstacle next to trees and buildings to contain RF.
Proper design allows the reuse of frequencies in another
geographical area in the same metropolitan region without
interference (crosstalk, dropped calls, etc.). Achieving this
requires careful site location, antenna height above ground and
antenna type. But, with reuse, more calls can be placed
simultaneously than there are frequencies available.
The Riverton cell site is placed to contain signals to an area
approximately 2 miles in radius. In addition to being contained,
signals from a cell must also propagate (travel) far enough to link
up (overlap) with signals from neighboring cell sites. Precluding
this, calls would become very noisy and possibly drop before
handing off to the neighboring cell as the phone drove away from
the initial cell.
The 120' antenna height is required specifically for overlap
to two neighboring cell sites. One is a proposed site in BurienU)
the other is an existing site in McMicken Heights( I have attached
a map inidicating the locations of all three cells. The solid red,
blue and black lines are contours of equal signal from each of the
three sites. These lines were obtained through actual field
measurements. Each line indicates approximately where signal
levels were measured to be -75dBm to -80dBm (a smaller negative
number indicates a stronger signal). This is the level we desire
to have calls handoff. If this level were lower, say - 85dBm, then
the call would become noisy before handing off to a stronger
signal. As the drawing shows the 75 -80dBm contours for Burien
(red) and Riverton (black) do not overlap completely, thus handoffs
from Riverton to Burien or v.v. will experience slight degradation
in the shaded, area. Without testing a 100' height at Riverton I
determined that that height was not useable due to the marginal
signals measured at 120'. Usually sites located close to the base
of a hill (such as this) require a higher tower to cover the top of
the hill vs. a tower farther away from the base of,the hill.
Finally, containing signal from such a high height will be
realized through the selective use of antennas. Coverage of the
hill towards Burien will use a small, very directional antenna
aimed towards the shaded area. Additional antennas will be
installed at a lower height to cover north and east. The lower
height will make up for the lack of sufficient terrain to obstruct
the signal from traveling too far to the north and east. As these
antennas are lower their signals will be more obstructed by trees
and buildings. Therefore, it is necessary to radiate additional
power, possible on .y_ith_...tg h use of higher gain antennas.

Yes
10. Describe the manner in which you believe that your request for a Conditional Use Permit
will satisfy each of the following criteria as specified in TMC 18.64.030 (attach additional
sheets, if necessary).
A. The proposed use will not be materially detrimental to the public welfare or injurious
to the property or improvements in the vicinity of the proposed use or in the district in
which the subject property is situated.
RESPONSE:
The operation will create very little traffic (1 visit per month by technician plus
any repar visits). Noise will be less than ambient highway noise. No proce55es
will create impacts off -site or hazardous emissions or spills. Radio frequencies and
signal strength will not interfere with other electronic processes or equipment in
the industrial area, nor create any health risks for persons living or working in the
area.
B. The proposed use shall meet or exceed the performance standards that are required
in the district it will occupy.
RESPONSE:
Applicants will discuss structure colors and site screening with City staff and will
follow specifications recommended by staff and agreed to by BAR.

C. The proposed development shall be compatible generally with the surrounding land uses in
terms of traffic and pedestrian circulation, building and site design.
RESPONSE:
Extremely low traffic, will not generate or impede pedestrian traffic. Building
and site design will be of higher quality than existing adjacent development
D. The proposed use shall be in keeping with the goals and policies of the Comprehensive
Land Use Policy Plan.
RESPONSE:
The site is in a Manufacturing area where existing and future land uses are least
likely to conflict with it (no consistent, existing pattern). The site uses a
remote property remnant on a highway interchange, generally unsuited to and therefore
not affecting or displacing other Manufacturing uses. The use is located in an
area where the view from the surrounding residential areas (ni.11side to West) already
includos similar, pole --typo vicual elemonts.
E. All measures have been taken to minimize the possible adverse impacts which the proposed
use may have on the area in which it is located.
RESPONSE:
See siting factors noted above; the pole height is the minimum necessary to serve
the local area with this utility service from a single site, without proliferation
of such sites in the same geographic area and visual area.

RE: SEA Riverton
The following is a description of the status of all properties in the
Riverton area that would provide a feasible location for a 1J S WEST
NewVector cell site, and would meet the zoning requirements for the
City of Tukwilla:
1) Kaiser Gateway Assoc. Willing to roof mount antennas at
height of approximately 15 feet,
not willing to allow for additional
height.
2) Boeing Employees Credit Union Not Interested.
3) Bedford Development Company No Room.
4) Willard Levine No Room.
5) Mobile Oil Corporation Not Interested.
6) Unocal Corporation Not Interested.
7) Texaco Inc. Not Interested.
8) Donald Wilson No Room.
9) Denny's Inc. Not Interested.
Based on our research of the area, there are no properties within the
height exemption area that would provide an adequate location for a
NewVector cell site. If NewVector is to build a cell site in the
Tukwilla area, it will be necessary to pursue zoning relief in the
areas surrounding the height exemption area.
If you have any questions or comments, please contact us at 562 -3054.
Thank you.
