V. COMMENTS
In response to the notice of application, written comments (dated June 28, 2001) were
received from Donna Hogerhuis, Muckelshoot Cultural Resources Program. The comments
included a request for an archaeological survey before any ground disturbing activities
because of proximity of the subject site to the Green River. However after reviewing the
plans and conducting a site visit, another letter dated July 18, 2001, from Donna Hogerhuis
was received that stated that the proposed project was not impacting Tribe's cultural
interests. The letter also requested that if archeological or historic materials were discovered
during the construction, all activity must be stopped and Muckelshoot Cultural Resources
Program and the State Archaeologist must be contacted. This request will be a condition of
the shoreline permit approval.
Written comments dated July 16, 2001, were also received from Dave Clark, King County
Water and Land Resources Division. The letter from Dave Clark requested that any
improvements at this site to be fully consistent with the presence and operation of the levee
improvements. Also, there are a series of dewatering wells and a pump station associated
with existing levee on the subject site. The comment letter expressed concern about the
impact of filling and paving on the load bearing capacity around the existing well caps and
wet well structures. In response to comments received from King County, applicant was
asked to provide some additional information that included:
5
• •
1. Design calculations showing the improvements with respect to the well caps and the wet
well structure will have a load bearing capacity that will meet or exceed AASHTO
HS20 -44 loading requirements.
2. Notification of approval from the District Engineer of the US Army Corps of Engineers
for all improvements affecting the levee.
In response to the City's request for this information, applicant provided a letter from
GeoEngineers,Inc., analyzing the bearing capacity of well caps. It concluded that the soil
bearing capacity will be adequate to support an H20-44 wheel load with minimal deflection.
This information was reviewed by the City's Public Works Department and they concurred
with the report's findings.
Also, the applicant contacted Noel Gilbrough, Army Corps of Engineers, to get their
approval. Army Corps of Engineers was concerned about the planting of trees and their
impact to the stability of the levee. The project was revised to not include any planting of
trees in the vicinity of the levee. Noel Gilbrough will be forwarding his comments in writing
prior to issuance of the shoreline permit. However verbal confirmation from Noel Gilbrough
that Army Corps of Engineers approved all the proposed improvements except the tree
planting aspect, was received by the City on September 18, 2001.
VI. CONCLUSION
The proposal can be found to not have a probable significant adverse impact on the
environment and pursuant to WAC 197 -11 -340, a Determination ofNonsignificance (DNS)
is issued for this project
This DNS is based on impacts identified within the environmental checklist, attachments,
and the above "Final Staff Evaluation for Application No. E01- 015 ", and is supported by
plans, policies, and regulations formally adopted by city of Tukwila for the exercise of
substantive authority under SEPA to approve, condition, or deny proposed actions.

Consultation
Building 734 and 741 Well Caps
Segale Business Park
Tukwila, Washington
File No. 0291 -019 -00
This presents GeoEngineers conclusions regarding bearing capacity of well caps constructed
over existing dewatering well casings adjacent to Buildings 734 and 741 at the Segale Business
Park. GeoEngineers previously evaluated potential for settlement and embankment stability in
regard to proposed fill placement to increase grade behind the subject buildings as described in
our May 21, 2001 report. We also developed recommendations for fill placement and
compaction.
Based on review of well cap "as- built" construction details done by Layton and Sell that you
provided, the well caps comprise a circular cap of unreinforced concrete with a diameter of about
5 feet. A 20 -inch diameter steel lid protects 18 -inch diameter corrugated metal pipe (CMP)
which extends through the concrete cap to access the dewatering wells. The concrete well cap
thickness ranges from about 6 inches at the perimeter to about 2 feet around the collar of the
CMP. The dewatering wells comprise 8 -inch diameter schedule 80 polyvinyl chloride pipe
located inside the CMP. We understand the well caps will be subjected to H20-44 wheel loads.
The structural fill placed to establish subgrade beneath the concrete well caps was compacted
and consists of crushed gravel and rock spalls. Based on the Layton and Sell Building 734 and
741 access area drawings dated May 31, 2001, it is our opinion the soil bearing capacity will be
adequate to support an H20-44 wheel load with minimal deflection. We estimate the allowable
soil bearing capacity is at least 4,000 pounds per square foot. The structural capacity of the
concrete well cap may also be evaluated using a subgrade modulus of 300 pounds per cubic inch.

RE: Tukwila: Segale Business Park
Parking Lot Project
Thank you for contacting our office with information regarding the Segale Business Park:
Parking Lot Project. As I discussed with you by phone, I had concerns over the location of the
project near Green River. In visiting the project site and reviewing the information sent to us it
appears that this project is not impacting the Tribe's cultural interests. This comment is based on
the scope of work and amount of previous disturbance at this location from the development of
both the river dike and building.
Please inform this department of any changes within the scope of your project's footprint.
Any changes may need to be reviewed. Should additional information become available, our
assessment may be revised. If archaeological or historic materials are discovered during the
course of your project's activities, especially during utilities or drain line trenching, we ask you
to stop activity and contact this office and the State Archaeologist.
You may want to contact the Wildlife Program and Fisheries Program, which are separate
departments under the Muckleshoot Indian Tribe. Notice or consultation with this department
should not be presumed to represent Tribal policy or as sufficient notice or consultation
regarding other departments.
I appreciate the opportunity to make comment on this project.

Dear Mr. Lancaster:

COMMUNITY
DEVELOPMENT
This letter is to convey to you my comments and concerns with respect to proposed
placement of fill and paving adjacent to the Green River Levee along the east side of
Buildings 734 and 741 in the SegaleBusiness Park, pursuant to Shorelines Permit L01 -039.
King County is signatory to interlocal agreements with the City of Tukwila to provide
maintenance and operation of this levee, which provides flood containment for Green River
flows affecting the subject properties, together with substantial Portions of the Southcenter
area in Tukwila. The affected levee segment is part of the larger federally authorized Lower
Green River Flood Control Project undertaken by the United States Army Corps of
Engineers, under the sponsorship of the City of Tukwila. King County undertakes these
responsibilities through its operation of the Green River Flood Control Zone District
(GRFCZD). Over the past ten years, substantial investments of public funds have been made
in this particular levee location to secure the structural stability and continued function of the
Segale Levee.
The main purpose of this letter is to emphasize the need for any improvements at this site to
be fully consistent with the ongoing presence and operation of the subject levee
improvements. These include a series of dewatering wells and an associated pump station.
These improvements have been constructed and are operated to provide for adequate levels
of stability in otherwise saturated foundation soils supporting the levee structure. The wells
penetrate to groundwater depths and are linked to a conveyance manifold draining to a wet
well and submerged pumping system, which discharges through the levee prism. The well
tubes and associated manifold system have been installed in accordance with design
specifications which have not included the types of additional loading now anticipated at this
site location. Based on my earlier meeting and discussions with the property owner, I am
Steve Lancaster
July 16, 2001

assuming these uses will include the loading and unloading of tractor trailers similar to those
addressed in Section 1.2.5 (C) of the American Association of State Highway and
Transportation Officials' (AASHTO's) Standard Specifications, Twelfth Edition.
Therefore I respectfully request that any approvals for filling and paving of this site
uniformly require upgrades of the load- bearing capacity around each of the well caps and the
wet well structure, such that bearing capacity will meet or exceed AASHTO HS20 -44
loading requirements.
Further, please note that all proposed work potentially affecting the structural configuration
or flood containment function of a federally authorized levee will require a formal prior
determination by the District Engineer that the subject improvements will not adversely -
affect the structure or function thereof.
Thank you for the opportunity to comment on this proposal. If you have any question about
this request, please call me at 206 - 296 -8388.

To Ms. Dhaliwat, RE: L01 -039 Shoreline Permit, E01 -015 SEPA
Thank you for sending the site plans to me for review. While I have not received the plans
yet in the mail, I would like to comment on this proposal to re- grade, fill and pave 1.3 acres near
the Green River. The Muckleshoot Tribe traditionally lived along waterways from the Cascade
Mountains to areas beyond Lake Washington and Elliot Bay. The Tukwila area is extremely
significant, unique, and well documented in its reference to tribal mythologies, prehistoric and
historic villages and fishing sites. For decades, archaeological surveys and excavations have
identified the Tukwila - Renton area as high potential for archaeological discovery.
Due to the location near the Green River, the Cultural Committee will probably request
that an archaeological survey before any ground disturbing activities are started. While the region
is developed., an unpaved parking lot, such as an overflow area, may be relatively undisturbed. I
would like to confirm this with a site visit. As you may be aware, grading can often do irreparable
harm to a site. Paving an area is also an impact. Once a site is paved, the information contained in
that site is sealed making data recovery impossible. This may be a good solution in order to
protect a site permanently. However, the Tribe should be a part of any mitigation to a cultural site
of concern to the Tribe.
If you decide to request a survey prior to my review of the site plans, I would like to
request to review and comment on archaeological report. If you have any questions, please
contact me at 360 - 802 -2202, extension 100.

plate oil/water separator, and river enhancement tree planting. Fill quantity is about 4,000 c.y., and
pavement area is about 1.3 acres.
11. Location of the proposal. Give sufficient information for a person to understand the precise .
location of your proposed project, including a street address, if any, and section, township, and
range if known. If a proposal would occur over a range of area, provide the range or boundaries
of the site(s). Provide a legal description, site plan, vicinity map, and topographic map, if
reasonably available. While you should submit any plans required by the agency, you are not
required to duplicate maps or detailed plans submitted with any permit applications related to
this checklist.
The fill area is shown on the attached site plan (Exhibit B), and located on the attached vicinity map
(Exhibit C). The project site is located on tax lot # 352304 -9018, in the Section 35, Township 23 North,
Range 4 East, W.M., on the east side of Segale Drive A (18338 & 18290 Andover Park W., Tukwila).
12. Does the proposal lie within an area designated on the City's Comprehensive Land Use Policy
Plan Map as environmentally sensitive?
Yes — within 200 feet of the Green River.
B. ENVIRONMENTAL ELEMENTS

a. General description of the site (circle one): flat, rolling, hilly, steep slopes, mountainous,
other: Applicable items are underlined.
b. What is the steepest slope on the site (approximate percent slope)?
Almost all of the site including the area to be paved is flat, although the levee on the east edge
of the work area has slopes of approximately 2H:1 V.
c. What general types of soils are found on the site (for example, clay, sand, gravel, peat,
muck)? If you know the classification of agricultural soils, specify them and note any
prime farmland.
Sand and gravels.
d. Are there surface indications or history of unstable soils in the immediate vicinity?
If so, describe.
No.

Environmental Checklist
e. Describe the purpose, type, and approximate quantities of any filling or grading
proposed. Indicate source of fill.
Placement of approximately 4,000 c.y. of crushed rock fill with asphalt paving surface, to raise
ground elevation about 3.5 feet in a rear access area that serves existing warehouse buildings.
The fill will come from our stockpile on Segale Business Park property.
f. Could erosion occur as a result of clearing, construction, or use?
If so, generally describe.
None is expected because the site is relatively flat, and will have erosion control measures.
About what percent of the site will be covered with impervious surfaces after project
construction (for example, asphalt or buildings)?
9.
Over 90% of the site will be covered with impervious surfaces. These include buildings, parking,
driveways and sidewalks. The site currently is about the same (only change is from impervious
gravel to impervious asphalt).
h. Proposed measures to reduce or control erosion, or other impacts to the earth, if any:
Silt fences and sediment traps will be used to control storm water prior to discharge into existing
onsite catchbasins. During construction new catchbasins will be installed. All catchbasins will
have CB protection.

YES - Continue to Question 1 -2
1 -2 Could the construction, operation, or maintenance of the project result in sediment transport off
site or increased rates of erosion and /or sedimentation in watercourses, the Green/Duwamish
rivers, or the Black River? Most projects that involve grading have the potential to result in
increased erosion and/or sedimentation as a result of disturbances to the soil or earth. If your
project involves grading and you have not prepared a Temporary Erosion and Sedimentation
Control Plan specifically designed to retain 100 percent of the runoff (including during
construction) from impervious surface or disturbed soils, answer Yes to this question. If your
project is normally exempt under the Tukwila Municipal Code and would not require the
preparation of a Temporary Erosion and Sedimentation Control Plan, BUT may still result in
erosion or sediment transport off site or beyond the work area, answer Yes to this question.
Please circle appropriate response.
NO - Continue to Question 1 -3
Continue to Question 1 -3
1 -3 Will the project result in the construction of new impervious surfaces? Impervious surfaces
include those hard surfaces which prevent or restrict the entry of water into the soil in the
manner that such water entered the soils under natural conditions prior to development; or a
hard surface area that causes water to run off the surface in greater quantity or at an increased
rate of flow from the flow presented under natural conditions prior to development (see TMC
Chapter 18.06, Tukwila Zoning Code, Page 18 -12). Such areas include, but are not limited to,
rooftops, asphalt or concrete paving, compacted surfaces, or other surfaces that similarly affect
the natural infiltration or runoff patterns existing prior to development. Please circle

1.3 PROJECT DESCRIPTION
The purpose of this project is to add approximately 4,500 cubic yards of structural fill material to
the gravel access area of buildings 734 & 741. The gravel access area is located between the
buildings east side and the existing levee. The purpose of the fill is to bring the existing grade
level up the finish floor elevation of the existing buildings and to buttress the existing levee. The
fill will be placed over an existing gravel surface and the top of the fill will be paved. There are
23 existing King County Department of Natural Resources levee well heads in the area
proposed to receive structural fill. The well heads will remain undisturbed and a new 24"
diameter manhole cover will be constructed over top of them. The new manhole rim elevations
will be about 8- inches above the existing rim elevations.
The existing private, access area drainage system will be repaired and upgraded to
accommodate the new grades. The drainage system will consist of catch basins, conveyance

1.0 PROJECT OVERVIEW 321 -09
piping and a coalescing plate oil /water separator. The upgraded drainage system will continue
to drain to the existing storm drain system in Andover Park W which drains to the P -17 regional
storm water basin. The P -17 basin was constructed as part of the City of Tukwila Andover
Industrial Park Comprehensive Drainage Plan. The basin is located just west of the Green
River at approximately Minkler Blvd, in the City of Tukwila.
Landscape plantings will be placed between the new edge of pavement and the existing top of
levee. Refer to the Ken Large Landscape Architect plans for details.
1.4 EXISTING CONDITIONS
The project site area is approximately 5.9 acres and is about 90% impervious and 10%
pervious. Of this total, approximately 1.5 acres will be disturbed. The disturbed area consists
of approximately 0.3 acres of pavement and 1.2 acres of compacted gravel surface. The site is
currently occupied by two commercial buildings (buildings 734 & 741), paved parking and
driveway areas, landscaping and the gravel access area on the east side of the buildings. At
present, the gravel access area near the building is approximately 3.5 feet below the existing
finish floor elevation. Drainage in this area is collected by an existing storm drain system which
conveys the drainage to an existing storm drain system in Andover Park W then on to the P -17
regional storm water basin.
1.5 DEVELOPED CONDITIONS
Developed conditions will replace approximately 0.3 acres of pavement and 1.2 acres of
compacted gravel surface with 1.3 acres of pavement and 0.2 acres of gravel surface.
Approximately 4,500 cubic yards of fill material will be placed over the existing gravel access
area along the buildings east sides. The fill material will bring the existing grade level up to the
existing building finish floor elevations and will buttress the existing levee. The existing access
area storm drainage system will be repaired and upgraded to accommodate the new grades.
The storm drain system's existing discharge to the drainage system in Andover Park W will
remain unaltered. Water quality treatment will be provided by a new coalescing plate oil /water
separator.
1.6 SITE SOILS
The site soils generally consist of dense sand and gravel fill with varying amounts of silt and
cobbles overlying native alluvial deposits consisting of silty sand with occasional layers of silt
and sandy silt to a depth of about 40 feet. Below this lies fine to medium sand with occasional
layers of silty fine sand and sandy silt to a depth of about 75 feet. Refer to appendix A for a
geotechnical evaluation by GeoEngineers dated May 21, 2001.
1.7 KING COUNTY CORE AND SPECIAL REQUIREMENT SUMMARY
CORE #1. DISCHARGE AT THE NATURAL LOCATION
The developed conditions will not alter the sites discharge location. At present, surface runoff
from the gravel access area is collected in catch basins and conveyed to the existing storm
drainage system in Andover Park W. Under developed conditions, the existing access area

1.0 PROJECT OVERVIEW 321 -09
storm drain system will be repaired and upgraded and will continue to drain to the storm drain
system in Andover Park W. The Andover Park W storm drainage system discharges to the P-
17 regional storm water basin.
CORE #2. OFFSITE ANALYSIS
A downstream analysis of the Andover Park W storm drainage system for the 981 building and
site improvements indicate that some portions of the existing Andover Park W storm drain
system may become surcharged during a 25 -year event. However, the elevation of the
hydraulic grade line was estimated to be several feet below the rims. The downstream analysis
modelled the 734/741 site as being 95% impervious surface which assumed that the existing
gravel access area was impervious. The results of the downstream analysis indicate that the
existing system has adequate capacity to convey and contain the 25 -year design storm event.
The existing storm drain system and the street are private. There are no known problems with
the existing downstream system. The owner has never observed storm water overflows from
any of the rims nor has storm water ever ponded in their streets or parking lots.
CORE #3. FLOW CONTROL
Flow control for the site is provided by the P -17 regional storm water basin. The P -17 basin
was constructed as part of the City of Tukwila Andover Industrial Park Comprehensive
Drainage Plan. The basin is located just west of the Green River at approximately Minkler Blvd,
in the City of Tukwila. The only runoff characteristic difference between the existing and
developed conditions is that the developed conditions propose to pave over an existing
compacted gravel surface. King County's KCRTS model treats compacted gravel surfaces as
impervious. Therefore, on the basis of modeling, there will be no change in the runoff volume
or peak flow. In practice, we anticipate that any additional runoff volume or peak flow would be
insignificant as the result of paving over a compacted gravel surface.
CORE #4. CONVEYANCE SYSTEM
The existing access area storm water collection /conveyance system will be upgraded to meet
the design requirements of a 25 -year design storm event using the rational method. The
existing downstream segment to the Andover Park W drainage system will be checked for the
10 -year design storm event using the rational method. The existing Andover Park W drainage
system was previously analyzed and was found to have adequate capacity to convey and
contain the 25 -year design storm event.
CORE #5. EROSION AND SEDIMENT CONTROL
Erosion and sediment control will be provided by installing temporary filter media inserts into the
catch basins receiving construction site runoff. Site perimeter protection is already provided by
the surrounding topography. Construction ingress and egress will occur on private, paved
roads.

CORE #6. MAINTENANCE & OPERATIONS
The maintenance and operation of the drainage system is the responsibility of the property
owner.
CORE #7. FINANCIAL GUARANTEES AND LIABILITY
To be determined.
CORE #8. WATER QUALITY
Water quality will be provided by a coalescing plate oil /water separator (CPS). The CPS is
designed to treat the 6 -month design storm event. Flows greater than the 6 -month will bypass
the CPS and will discharge directly to the existing downstream storm drain system. Larger
sediment particles will be captured in catch basin sumps and floating debris will be captured by
a tee type structure.
SPECIAL REQUIREMENT #1. OTHER ADOPTED AREA - SPECIFIC REQUIREMENTS
Not applicable.
SPECIAL REQUIREMENT #2. FLOODPLAIN /FLOODWAY DELINEATION
Refer to the separately bound Building 734 & 741 Access Area plan set by Layton & Sell, Inc.,
P.S., dated May 31, 2001 for 100 -year flood limits.
SPECIAL REQUIREMENT #3. FLOOD PROTECTION FACILITIES
It is our understanding that the existing levee has been designed to conform with FEMA
regulations.
SPECIAL REQUIREMENT #4. SOURCE CONTROLS
Source controls will include temporary filter media inserts in catch basins during construction.
Upon project completion, anticipated pollutants include small amounts of sediment, floating
debris and oil.
SPECIAL REQUIREMENT #5. OIL CONTROL
Oil control will be provided by a coalescing plate oil /water separator.

2.0 DRAINAGE CALCULATIONS 321 -09
Two drainage basins (Basin 1 and Basin 2) are delineated for the project. Basin 1 includes the
drainage areas on the north and east sides of building 741. Basin 2 includes the drainage area
on the east side of building 734. Refer to the Project Basin Map, Figure 1.0.
2.1 BASIN 1 SUMMARY
Basin 1 is about 2.5 acres in size and includes the drainage areas around the north and east
sides of building 741. Storm water collected in this basin is conveyed around the north side of
building 741. The 6 -month flow will be diverted through a new coalescing plate oil /water
separator (CPS). High flows will bypass the CPS and will discharge into the existing storm
drain system in Andover Park W.
The only difference between the existing and developed conditions is that the developed
conditions propose to pave over the existing compacted gravel surface. King County's KCRTS
model treats compacted gravel surfaces as impervious. Therefore, on the basis of modeling,
there will be no change in the runoff volume or peak flow. In practice, we anticipate that any
additional runoff volume or peak flow would be insignificant as the result of paving over a
compacted gravel surface.

2.2 BASIN 2 SUMMARY
Basin 2 is about 0.33 acres in size and includes the drainage area around the east side of
building 734. Storm water collected in this basin is conveyed around the south side of building
734. The 6 -month flow is diverted through an existing coalescing plate oil /water separator
(CPS) which was previously designed during the building 981 project to accommodate the 734
access area. High flows bypass the CPS and discharge to the existing storm drain system in
Andover Park W.
The only difference between the existing and developed conditions is that the developed
conditions propose to pave over the existing compacted gravel surface. King County's KCRTS
model treats compacted gravel surfaces as impervious. Therefore, on the basis of modeling,
there will be no change in the runoff volume or peak flow. In practice, we anticipate that any
additional runoff volume or peak flow would be insignificant as the result of paving over a
compacted gravel surface. The existing storm drain system in this area was previously
designed for a future paved surface.

A new CPS will be designed and constructed for Basin 1. Basin 2 will drain to an existing CPS
which was previously designed during the building 981 project to accommodate the 734 access
area.
2.3.1 WATER QUALITY DESIGN FLOW
Per King County, the water quality design flow is defined as 60% of the developed 2 -year peak
flow rate, as determined using the KCRTS model with 15- minute time steps calibrated to site
conditions. Alternatively, water quality flows may also be estimated using 64% of the 2 -year,
24 -hour precipitation in the SBUH model. The KCRTS method will be used here.

From the KCRTS analysis, for Basin 1, the 2 -year peak flow is estimated at 0.648 cfs.
Therefore, the water quality design flow is 0.39 cfs (0.648 *0.6) or 175 gpm.

Use Model 612 -SA.
2.4 FLOW CONTROL STRUCTURE
The 6 -month water quality design flow will pass to the CPS through a tee structure with an
orifice and notch weir. Flows greater than the water quality flow will overflow into a high -flow
bypass riser pipe and will discharge to the existing storm drain system in Andover Park W.
2.4.1 HIGH -FLOW BYPASS FLOW CONTROL STRUCTURE
The high -flow bypass structure will be a 12 -inch pipe. The invert is set at elevation 19.81 as
determined by the existing storm drain system that it will connect to. The rim of the overflow
riser will be set two feet above the invert, so the overflow rim will be at elevation 21.81. Based
upon the rational method, the 25 -year peak flow is estimated at 3.49 cfs and the 100 -year peak
flow is estimated at 3.77 cfs (see section 2.5 Conveyance Calculations).
Determine head over overflow riser rim for the 100 -year event, Q =3.77 cfs:
Q = C(L- 0.2H) *H^3 /2
where Q = flow (cfs)
C = 3.27 + 0.40 H/P (ft)
H = hydraulic head above rim of overflow (ft)
P = height of overflow rim above invert (2 ft)
L = circumference of overflow (3.14 ft)
3.77 = [3.27 + 0.40 H /2] *(3.14 - 0.2H) *HA3 /2
solving for H = 0.514', say 0.52', thus the 100 -year water surface elevation will be at
approximately elevation 22.33 (0.52 + 21.81).

3.0 GENERAL
The project site drainage discharges to an existing storm drain system in Andover Park W.
This system is shown on Figure 3.0 Basin Map Downstream Drainage System on page 3 -2.
The 734 access area is at the east end of Basin 12 and the 741 access area is at the east end
of Basin 13. A downstream analysis of the Andover Park W storm drainage system was
previously performed for the 981 building and site improvements (Basins 2 & 11). This analysis
indicated that some portions of the Andover Park W storm drain system may become
surcharged during a 25 -year event. However, the elevation of the hydraulic grade line was
estimated to be several feet below the rims. The downstream analysis modelled Basins 12 &
13 (734/741 site) as being 95% impervious surface which assumed that the existing gravel
access area was impervious. The results of the downstream analysis indicate that the existing
system has adequate capacity to convey and contain the 25 -year design storm event. The
existing storm drain system and the street are private. There are no known problems with the
existing downstream system. The owner has never observed storm water overflows from any
of the rims nor has storm water ever ponded in their streets or parking Tots.
The Andover Park W drainage system discharges to the P -17 regional storm water basin. The
P -17 basin was constructed as part of the City of Tukwila Andover Industrial Park
Comprehensive Drainage Plan. The basin is located just west of the Green River at
approximately Minkler Blvd, in the City of Tukwila.

Report of Consultation
Proposed Building 741 and 734 Improvements
Segale Business Park
Tukwila, Washington
File No. 0291 -019-00
INTRODUCTION AND SCOPE
This report summarizes our review and evaluation of potential building settlement and levee
embankment stability issues associated with certain proposed improvements to existing Buildings
741 and 734 at the Segale Business Park. Our scope for this study included review of existing
geotechnical reports by others, settlement analysis and embankment stability evaluation based on
information derived from our review, and our experience at the Segale Business Park.
Specifically, we reviewed a geotechnical report on seepage and stability of the levee by Shannon
& Wilson, Inc. dated June 1995, and portions of a geotechnical report for the construction of the
business park performed in about 1972 by Dames & Moore, Inc. Our scope also included
developing recommendations for site preparation and earthwork for the proposed improvements.
PROJECT UNDERSTANDING
Buildings 741 and 734 are located about 50 feet landward from the toe of the existing levee
on the left bank of the Green River. We understand finish floor for both buildings at about
Elevation 27 feet (King County Aerial Survey Datum). Exterior glade between the buildings and
the toe of the levee is at about Elevation 22 feet to provide rail access behind the buildings. The
proposed improvements include eliminating the rail access and raising grade by filling between
the buildings and the levee to about Elevation 27 feet.
The top of the levee is at about Elevation 32.5 feet. The landward slope of the levee is
inclined at about 2H: IV (horizontal:vertical), and the riverward slope of the Levee is inclined at
about 1.75H:1V. The riverward slope of the levee has a riprap facing with the toe at about
Elevation 2 feet.

DATA REVIEW
The Shannon & Wilson report describes site exploration, testing, and analysis for their
evaluation of seepage and stability of the levee at the Segale Business Park. Three areas of
concern were identified: 1) piping through the levee, 2) failure of the landward slope and toe by
high uplift pressures, and 3) failure of the riverward slope of the; levee by toe scour and during
rapid drawdown. Shannon & Wilson concluded that the landward slope of the levee was
potentially unstable during maximum river flows because of high uplift pressures. They proposed
a stabilizing berm at least 5 feet high and placed along the toe; of the landward slope. They
recommended a system of relief wells be installed in areas where installing a stabilization berm
was not practical or undesirable because of the existing rail access behind the buildings.
Based on review of subsurface conditions disclosed in boring logs prepared by Dames .&
Moore, Inc., the native alluvium in the vicinity of Buildings 741 and 734 (Boring B -2) comprises
silty sand with occasional layers of silt and sandy silt to a depth of about 40 feet. Below this
depth the boring log discloses fine to medium sand with occasional layers of silty fine sand and
sandy silt to a depth of about 75 feet.
DISCUSSION AND CONCLUSIONS
We understand site preparation for the Segale Business Park included a preload surcharge of
the building pads before building construction. We further understand that the surcharge fill was
placed to about Elevation 32 feet (5 feet above finish floor grade) and extended beyond the
building perimeters at full height for a horizontal distance of about 15 feet. On this basis, we
conclude that raising grade to Elevation 27 feet between the buildings and the toe of the levee as
proposed, should not result in differential settlement of a magnitude that could adversely impact
the existing Buildings 741 and 734.
It is our further understanding that relief wells were installed along the toe of the levee in this
portion of the Business Park as an alternative to placing the stabilization berm. Accordingly, it is
our opinion that raising grade as proposed should not adversely :impact levee stability provided
the relief wells are protected from damage during construction.
RECOMMENDATIONS
EARTHWORK
Site Preparation
The earthwork anticipated at the site will consist of stripping and grubbing, excavation and/or
recompaction of loose or soft soils, subgrade preparation and :placement and compaction of
structural fill. Prior to grading, the areas to be developed should be stripped of all vegetation and
cleared of all surface and subsurface debris. We expect that stripping depths will likely be on the
order of 6 to 8 inches. Additional stripping depths will likely be necessary in areas of heavy
vegetation. Disturbance to a greater depth should also be expected if earthwork is performed
during wet weather.

We recommend that a member of our staff evaluate the exposed subgrade conditions after
removal of vegetation and topsoil. The exposed subgrade can be. evaluated by proofrolling with
heavy rubber -tired construction equipment prior to placement of structural fill. During wet
weather, it will probably be necessary to evaluate the subgrade by probing with a steel rod rather
than proofrolling.
Any other soft, loose or otherwise unsuitable areas that are encountered during the subgrade
evaluation should be recompacted or overexcavated and replaced with structural fill. Our field
representative can assist in determining which will be the most effective method.
Wet - Weather Construction Considerations
The soil at the site contains a high percentage of fines (soil particles smaller than the No. 200
sieve). The fines cause the soils to be very sensitive to excess 'moisture. When the moisture
content of these soils is above the optimum percentage, construction traffic will rapidly disturb
and soften exposed subgrades. Even when moderately wet, it is very likely that the subgrades
will not tolerate repeated passes with construction equipment. Proper compaction of these wet
soils is not practical, in our opinion, and they often have to be removed from the site and replaced
with suitable imported structural fill.
Structural Fill Material.
Structural fill materials should be free of debris, organic contaminants, and rock fragments
larger than 6 inches. We recommend structural fill consist of granular material that is well graded
between coarse and fine sizes, and has less than about 10 percent finer than a U.S. No. 200 sieve.
Structural Fill Placement
All fill placed beneath pavement should be placed as structural fill. Structural fill should be
placed in horizontal lifts and uniformly compacted. The appropriate lift thickness will depend on
the material and the compaction equipment being used. A loose lift thickness of 8 to 12 inches is
typical when using heavy -duty vibratory equipment. All excavations should be wide enough to
accommodate the appropriate compaction equipment for the thickness of the fill.
The upper 2 feet of structural fill placed below pavement should be compacted to at least 95
percent of the maximum dry density (MDD) determined in accordance with ASTM D -1557 test
procedure. Fill placed more than 2 feet below the subgrade surface in these areas should be
compacted to at least 90 percent of the MDD.
Drainage
All ground surfaces, pavements, and sidewalks should slope away from the buildings.
Surface water runoff should be controlled by a system of curbs, berms, drainage swales, and/or
catch basins, and be discharged into a storm water collection system. Roof drains should be
tightlined to discharge into the storm water collection system.

REPORT LIMITATIONS AND GUIDELINE FOR USE'
This attachment provides information to help you manage yolir risks with respect to the use
of this report.
GEOTECHNICAL SERVICES ARE PERFORMED FOR gPECIFIC PURPOSES,
PERSONS AND PROJECTS
This report has been prepared for use by the Segale Business park GeoEngineers structures
our services to meet the specific needs of our clients. For example, a geotecimical or geologic
study conducted for a civil engineer or architect may not fulfil the needs of a construction
contractor or even another civil engineer or architect that are involved in . the same project
Because each geotechnical or geologic study is unique, each geotet;hnical engineering or geologic
report is unique, prepared solely for the specific client and project site. No one except the Segale
Business Park should rely on this report without first conferring with GeoEngineers. This report
should not be applied for any purpose or project except the one originally contemplated.
MOST GEOTECHNICAL AND GEOLOGIC FINDINGS ARE PROFESSIONAL
OPINIONS
Our interpretations of subsurface conditions are based on review of subsurface information
developed by others at widely - spaced locations at the site. Site exploration identifies subsurface
conditions only at those points where subsurface tests are conducted or samples are taken.
GeoEngineers reviewed field and laboratory data by others and then applied our professional
judgment to render an opinion about subsurface conditions throughout the site. Actual subsurface
conditions may differ, sometimes significantly, from those indiciited in this report. Our report,
conclusions and interpretations should not be construed as a warranty of the subsurface
conditions.
GEOTECHNICAL ENGINEERING REPORT RECOMMO1DATIONS ARE NOT
FINAL
Do not over -rely on the preliminary construction recommnenilations included in this report.
These recommendations are not final, because they were; developed principally from
GeoEngineers' professional judgment and opinion. GeoEngineers' recommendations can be
finalized only by observing actual subsurface conditions kevealed during construction.
GeoEngineers cannot assume responsibility or liability for this repprt's recommendations if we do
not perform construction observation.

Sufficient monitoring, testing and consultation by GeoEngineers should be provided during
construction to confirm that the conditions encountered are consistent with those indicated by the
explorations, to provide recommendations for design changes Should the conditions revealed
during the work differ from those anticipated, and to evaluate whether or not earthwork activities
are completed in accordance with our recommendations. ; Retaining GeoEngineers for
construction observation for this project is the most effective Method of managing the risks
associated with unanticipated conditions.
A GEOTECHNICAL ENGINEERING OR GEOLOGIC REPORT COULD BE
SUBJECT TO MISINTERPRETATION
Misinterpretation of this report by other design team member's can result in costly problems.
You could lower that risk by having GeoEngineers confer with appropriate members of the
design team after submitting the report. Also retain GeoEngineers to review pertinent elements
of the design team's plans and specifications. Contractors can also misinterpret a geotechnical
engineering or geologic report. Reduce that risk by having GeoEngineers participate in pre -bid
and preconstruction conferences, and by providing construction observation.
CONTRACTORS ARE RESPONSIBLE FOR SITE SAFETY ON THEIR OWN
CONSTRUCTION PROJECTS
Our geotechnical recommendations are not intended to direct the contractor's procedures,
methods, schedule or management of the work site. The contractor is solely responsible for job
site safety and for managing construction operations to minimize #isles to on -site personnel and to
adjacent properties.
READ THESE PROVISIONS CLOSELY
Some clients, design professionals and contractors may not recognize that the geoscience
practices (geotechnical engineering or geology) are far less ex$ct than other engineering and
natural science disciplines. This lack of understanding can credte unrealistic expectations that
could lead to disappointments, claims and disputes. GeoEngineers includes these explanatory
"limitations" provisions in our reports to help reduce sucll risks. Please confer with
GeoEngineers if you are unclear how these "Report Limitations and Guidelines for Use" apply to
your project or site.
