B. ENVIRONMENTAL ELEMENT
1. Earth
a. General description of the site (circle one): Flat, rolling, hilly, steep slopes,
mountainous, other:
The site is currently developed with landscaping and paving. The only slopes that
exist are 2% to catch basins and 5% to existing loading dock.
b. What is the steepest slope on the site (approximate percent slope)?
Approximately 4.9 %. At sloping pavement adjacent to existing dock doors at the
north face.
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.
Per Geotechnical Engineering Study by Earth Consultants, Inc., dated October 03,
2000, (revised October 23, 2000) the soils are silty sand with gravel, lightweight
fill (hog fuel), loose to dense sand, silt and clay. See attached soils report.
d. Are there surface indications or history of unstable soils in the immediate vicinity?
If so, describe.
Yes. The existing building is supported on piling.

Applicant Responses:
Agency Comments:
e. Describe the purpose, type and approximate quantities of any filling or grading
proposed. Indicate source of fill.
Fill materials of about 56 cy will be imported from an approved offsite barrow to
infill the north parking area so that it will drain away from the building. Fill
materials will be needed to support patching of the existing structural floor slab.
Pea gravel fill will be used in electrical conduit trenches. Where there are no
underslab utilities, compacted gravel fill will be placed under slab patches.
f. Could erosion occur as a result of clearing, construction, or use? If so, generally
describe.
Erosion could occur when paving is removed for generator yard, landscaping, new
paving and trenches. Erosion could also occur during interior slab demolition and
foundation work when the building roof is removed.
g.
About what percent of the site will be covered with impervious surfaces after
project construction (for example, asphalt or buildings)?
The current 6.23 acre (271,379 SF) site has 238,400 SF of impervious surface.
Overall impervious area is being reduced by 3,975 SF. The site presently is
covered by 87.8% impervious surfaces. This proposal will result in a 86.4%
impervious surface, a reduction of 1.4% of impervious surface. The net effect on
water quality and run off should be insignificant
h. Proposed measures to reduce or control erosion, or other impacts to the earth, if
any:
Best Management Practices (BMPs) — inceptor trenches, temporary dewatering,
standard cover materials, seeding. A detailed erosion control plan and contingency
plan will be provided to the city. The applicant will monitor all run off to Riverton
Creek, the storm drainage outlet for the site, and divert any unsatisfactory run off.
2. Air
a. What types of emissions to the air would result from the proposal (for example,
dust, automobile odors, industrial wood smoke) during construction and when the
project is completed? If any, generally describe and give approximate quantities if
known.
The site is primarily hard surface and some dust is expected during exterior site
work modifications. Should emissions become excessive, appropriate measures
will be taken to control them. Dust will be generated during the demolition of the
existing building improvements. These emissions will be controlled by the
contractor through his management practices.
b. Are there any off -site sources of emissions or odor that may affect your proposal?
If so, generally describe.
This is a heavy industrial zoning in which minor regulated emissions from bus
repair and maintenance occur on nearby property. These emissions are not
expected to affect the use of the property by Telegis.
c. Proposed measures to reduce or control emissions or other impacts to air, if any:
Puget Sound Air Pollution Control Agency requirements will be met. The agency
indicated per Article 6, Section 6.03 -4, emergency generators are exempt during
normal and maintenance operation. Test time for generators will be managed to
minimize the impact of exhaust from the units during testing and start up.

INTRODUCTION
The following report documents the results of a noise assessment and
recommendations for the Telegis Data Center in Tukwila, Washington. The objectives
of the assessment were:
• to predict noise levels at the property line during a period of normal operation of the
equipment in the building; and
• to evaluate the noise levels at the property line with respect to the City of Tukwila
. Noise Ordinance.
EQUIPMENT
The new mechanical system equipment planned for the Telegis Data Center includes
the following:

General information and acoustical data for the equipment are enclosed. The noise
generated by these units and received at the neighboring properties was assessed in
relationship to the City of Tukwila Noise Ordinance requirements.
NOISE ORDINANCE
The property for the Telegis Data Center has a Class MIC -H Industrial zoning
designation. All the surrounding properties are zoned industrial as well. Residentially
zoned properties exist 2380 feet to the south, across South 126th Street, and 1800 feet
to the west, across Pacific Highway South.
The City of Tukwila Ordinance' limits the noise generated by an industrially zoned
property and received by a residentially zoned property to 60 dB(A) between the hours
of 7:00 AM and 10:00 PM. Between the hours of 10:00 PM and 7:00 AM during
weekdays, and between the hours of 10:00 PM and 9:00 AM on weekends, the
Ordinance limits the noise levels to 50 dB(A).

Additionally, the Ordinance limits the noise generated by an industrially zoned property
received by an industrially zoned property to 70 dB(A) during daytime and nighttime
hours.
Furthermore, the noise ordinance exempts sounds "created by emergency equipment
and work necessary in the interests of law enforcement or for health, safety, and welfare
of the community" under section 8.22.150. We interpret the noise ordinance in
consideration of emergency generators for facilities serving the community as follows:
• During emergency generator routine maintenance, which is typically planned
for daytime hours, the generator should not exceed noise ordinance limits.
• During power outages, which may occur at anytime during the day or the
night, the noise generated by the emergency generator is exempt from the
Noise Ordinance.
Therefore, the emergency generator noise is governed by the Noise Ordinance
requirements only when the generator is operating for routine maintenance and is
exempt from the Noise Ordinance requirements when the generator is operating during
power outages.
Additionally, the condensing units are operating on a continuous cycle, 24 hours a day,
and consequently must meet both daytime and nighttime ordinance limits.
PREDICTED NOISE LEVELS
Equipment noise received at the neighboring properties was predicted based on a point -
source noise propagation model. Barrier attenuation was used in the model where the
building itself, the rooftop parapet, or grade features acted as a barrier. Predictions
were made for noise received at the property lines at grade level. It is understood that
only one generator will be exercised at a time during maintenance operation.
Therefore, predictions were made for only one generator operating.
Using the model described above, the noise received at the adjacent properties was
predicted for the condensing units, generators, transformers, and Toad bank as shown in
the following table.

Table 2: Predicted Noise Levels, in dB(A) re 20 µPascals
Page 2
As the above table indicates, the noise generated by the equipment and received at the
adjacent properties is expected to exceed the City of Tukwila Noise Ordinance limit of
70 dB(A) at the north, west, and east industrial properties as well as the nightime noise
ordinance limit of 50 dBA at the south and west residential properties.
RECOMMENDATIONS
In order for the equipment to meet ordinance requirements, we recommend
implementing one of the following options:
Option 1: _
Condensing Units
❑ Install a set of barriers around the units as shown in Figure 1 in Appendix III. The
top of the barrier should be 10' above the roof surface. The bottom of the barrier
may be held between 6" and 12" above the roof surface to allow for drainage. The
barrier should consist of continuously solid material that has a surface mass of at
least 2.5 pounds per square foot. 3/4" thick exterior grade plywood or 20 gage
sheetmetal meet this requirement.
Load Bank and Transformers
o Install a barrier around the Toad bank, transformers, and generators as shown in
Figure 2 in Appendix III. The top of the barrier should be 18' above grade. The
barrier should consist of solid material that has a surface mass of at least 2.5
pounds per square foot. 3/4" thick exterior grade plywood or 20 gage sheetmetal
meet this requirement.

APPENDIX I: GENERAL DISCUSSION OF NOISE
Environmental noise typically refers to the total acoustic environment as measured or
heard by humans. This acoustic environment is made up of background noise caused
by distant traffic, airplanes, etc., and higher level noise dominated by nearby sources
such as car pass -bys, airplane flyovers, or close construction activity. The most
commonly used measure of sound is the sound pressure level (SPL), which represents
the magnitude of the sound pressure in the air.
The human ear responds differently to sounds at different frequencies (pitch). This is
demonstrated by the fact that we hear higher pitched sounds easier than lower ones of
the same magnitude. To compensate for the different "loudness" as perceived by
humans at different pitches, a standard weighting curve is applied to measured levels.
This weighting curve represents the human ear's sensitivity, and is labeled "A"
weighting. The units of magnitude of the sound are written dBA ( "A" weighted decibels),
which is a logarithmic scale.
The nature of dB scales means that individual dB ratings for different noise sources
cannot be added directly to give the dB rating of the combination of these sources. Two
noise sources producing equal dB rating at a given location will produce a composite
noise that is 3 dB greater than the individual levels. Similarly, the loudness of sounds
does not vary arithmetically. The ear has some difficulty detecting the difference in
loudness between sounds that have a difference of 3 dB. A 5 dB difference is easily
detectable, and a sound that is 10 dB more than another sounds twice as loud.
The following table presents examples of common noise levels:
SPL(dBA) Example
0 Threshold of audibility
20 Quiet rural area (no traffic)
40 Suburban neighborhood (distant traffic)
60 Normal conversation
70 Busy freeway
100 Jackhammer
130 Threshold of pain
A noise descriptor is the Equivalent Noise Level Leg, which is the dBA level of a constant
sound which has the same acoustical energy as the time - varying noise. The EPA
describes it: "The equivalent sound level is a single value of sound level for any desired
duration, which includes all of the time - varying sound energy in the measurement
period ". Therefore, a sound that was 60 dBA for ten minutes, and 70 dBA for ten
minutes would have an Leg for the total time period of 67 dBA (remember, logarithms do
not add together directly). It can be seen that the higher level sounds are weighted
heavier in the calculation, because they have more energy.
The Ldn, or day -night equivalent sound level, is the Leg measured over a 24 hour period,
with a 10 dBA penalty applied to night -time levels (10:00 p.m. to 7:00 a.m.).

FEATURES AND BENEFITS
•
•
Liebert Air Cooled
\ Condensers
CONDENSER
The low- profile direct drive propeller
fan type air cooled condenser uti-
lizes either one or multiple separate
refrigeration circuits. Each balances
the heat rejection of the corre-
sponding compressor to match the
ambient temperature of the job.
Constructed of aluminum with a
copper tube aluminum fin coil, the
unit is quiet and corrosion resistant.
QUIET -LINE CONDENSERS
Quiet -Line condensers can help
your facility meet the strictest
noise codes and do so at less
cost than traditional condensers
with acoustical shielding.
EASY INSTALLATION AND
SERVICE
The condenser is quickly and easily
installed, because all internal wiring
is completed at the factory with only
electrical connections to be made
at the job site.
Your choice of five types of electrical
controls are available. Each is
mounted and wired in a panel
integral with the condenser.
Base unit includes a power block
for motor and line connections.
Main control (Lee -Temp) provides
a contactor and 24 V control cir-
cuit for remote control.
Fan cycling control provides for
head pressure control on multiple
fan units by cycling one or more
fans. Refrigerant pressure or ambi-
ent temperature provide the control
signal.
Fan speed control is a Liebert
proven method for providing the
finest electrical means of head
pressure control. Number one fan
(two fans on 6 and 8 fan models)
modulate in response to refriger-
ant pressure. The balance of fans
on multi -fan units cycle on ambi-
ent control. This option only avail-
able on 1 and 2 refrigerant circuit
models. (R -22 only)
An optional disconnect switch,
mounted in the electrical panel is
available for any of the above.
MAXIMUM RELIABILITY
Because these condensers are fac-
--' tory wired, piped, and tested, start-up
problems are eliminated, and relia-
bility of the overall system is greatly
increased.
FAN SPEED
WINTER CONTROL
The winter control system features
a variable speed motor specifically
designed to be used in conjunction
with the solid state fan -speed control
transducer. This transducer directly
senses the head pressure of the
compressor and varies the speed
of the fan to maintain constant con-
densing temperature and system
capacity. Auxiliary fan motors are
controlled by ambient thermostats.
This system allows for operation
at ambient temperatures as low
as —20°F when used with a low
pressure cutout time delay.
(Not available with Quiet -Line)
LEE -TEMP WINTER
CONTROL SYSTEM
The Lee -Temp winter control
system's heated receivers permit
startup and positive head pressure
control at ambient temperatures as
low as — 30 °F. The Lee -Temp pack-
age includes an insulated receiver,
a pressure relief valve, three -way
head pressure control valve, and.
roto lock valves. Mounting parts are
provided for field installation.

Laboratory tests were conducted on several representative soil samples to verify or
modify the field soil classificTtion and to evaluate the general physical properties and
engineering characteristics of the soil encountered. Moisture content tests were
performed on all samples. The results of laboratory tests performed on specific

Site Pre ' aration and Gener
I Earthwork
The proposed developmen areas along the northern exterior of the existing building
should be stripped and clea -ed of the existing asphalt pavement and other deleterious
materials. If desired, the existing asphalt pavement can be crushed and left in place
below the generator pad and proposed fill areas. The asphalt should be crushed into
fragments o',f three inches o Tess. Existing utility pipes that are abandoned should be
plugged or removed.
Structural fill placed around he proposed pile caps and grade beams should consist of
compacted granular fill. The ground surface where structural fill, or foundations are to
be placed should be observe by a representative of ECI. Loose or unstable subgrade
soils should be stabilized pr r to constructing the pile caps and grade beams. The
native soils are moisture sensitive, and will become unstable when exposed to
excessive moisture. Comp ction and grading of these soils will be difficult if the
moisture content of the soil i above the optimum moisture content.
FiII for use during wet weath r should consist of a fairly well graded granular material
having a maximum size of threee inches and no more than 5 percent fines p passing the
No. 200 sieve based on the minus 3/4 -inch fraction. p g
Structural fill s defined as compacted fill placed under foundations, roadways, slabs,
pavements, or other Toad- bearing areas. Structural fill under slabs and footings should
be placed in horizontal lifts nbt exceeding twelve (12) inches in loose thickness and
compacted to' a minimum of 90 percent of its laboratory maximum dry density_ The
maximum dry density should be determined in accordance with ASTM Test
Designation D -1557 (Modified Proctor). The fill materials should be placed at or near
the optimum moisture content. Fill under pavements and walks should also be placed
in horizontal lifts and compacted to 90 percent of maximum density except for the top
twelve (12) inches which should be compacted to 95 percent of maximum density.

Foundations
In our opinion, the propo4ed generator yard and new foundations throughout the
interior of the existing buil ing can be supported on pile foundations bearing in the
dense to very dense strata encountered at de the of a
five (55) feet. We understand the use of eighteen (18) nchldiaml diameter augercast piles s currently being considered. Driven pipe piles were previously considered, however,
due to potential driving str sses and related impacts to the existing structure they
were eliminated as an option. This report will specifically address eighteen (18) inch
diameter augercast piles. ECI can provide recommendations for other i
requested. pile types, if
The augercast piles should b embedded into the bearing strata a minimum distance of
five feet. A's discussed pre iously, the bearing strata was encountered at depths of
approximately fifty (50) feet to fifty -five (55) feet. For design, an allowable capacity
of sixty (60) tons can be used for eighteen (18) inch diameter augercast piles
embedded at least five (5) feet into the bearing strata. For piles embedded at least ten
(10) feet into the bearing strata, an allowable capacity of seventy (70) tons can be
used. For uplift, an allowable capacity of twenty (20) tons can be used for sixty
and seventy (70) ton axial capacity Y (60)
lateral load capacity of five (5) tons can be used, resistance
assuming one-inch of deflection (free
le
head condition). A point -of- fixity can be assumed at a depth of fifteen (15) feet (free
head condition)_ For fixed hel d conditions, an allowable capacity of ten (10) tons can
be used. The point of fixity or a fixed head condition can be assumed to be twenty-
.F(
w
four (24) feet. For short-term wind and seismic loading conditions, a one-third
increase in the above capacities can be considered.
Lateral resistance from grade beams and pile caps can be calculated using an
equivalent fluid of three hundred fifty (350) pounds per cubic foot (pcf). Friction along
pile caps and grade beams carp also be assumed for resisting lateral loads. For design,
a coefficient of friction of 0.35 can be used. Due to the related settlements, friction sf-iould be neglected for dynamic loading Iconditions. w The
above values ,assume the grade beams and pile caps are backfilled with granular
structural fills. The use of pea gravel backfill around pile caps is also acceptable.

The piles 'should be spaced with a center to center distance of at least three
diameters. The minimum
pacing can be reduced to one and one -half pile diameters
where new piles are plac adjacent to abandoned timber piles. Due to the loose
conditions bf the upper n tive deposits, a relatively large amount of grout may be
necessary to complete the piles. Ratios of pumped grout to the theoretical volume
could be. as high as two for some piles. ECI should be on -site during the pile
installation to verify bearing strata, depths of embedment, and pumped grout volumes.
Provided the foundations re installed in accordance with the recommendations
contained in this report, we estimate differential settlement between the new pile
groups will no exceed one - Ihalf inch. We understand the typical spacing of the pile
groups is approximately forty (40) feet. Most of the anticipated foundation
settlements should occur during construction as dead loads are applied.
•
Settlement Miti ation
I
As discussed previously, the existing grade will be raised along the north side building
to improve the drainage aro nd the building. Due to the compressible nature of the
soils at the site, the additionLof new fill will induce settlement and downdrag Toads on
the piles along the north per meter of the building. The addition of two feet to four
feet of fill along the north side of the building could result in settlements of up to four
inches and downdrag loads o up to ten (10) tons on the existing and new piles. The
addition of downdrag Toads c n the existing timber piles along the o t
the site couldresult in settlement of the piles and differential movement ofthe existin f
structure. Due to the potenti I adverse impacts of fill induced settlements on the new
and existing foundations, w recommend that measures to mitigate settlements be
considered.

To help mitigate fill induce settlements, the u•se of lightweight fill can be consider
The use ofihollow corrugated metal pipe in combination with lightweight fill can also
be considered as a measu a for introducing a lightweight mass into the fill area.
Lightweight fill usually consists of a pumped in place cementitious material that has a
unit weight ;that is typically one -fourth the unit weight of structural fill. For preliminary
pricing purposes, a unit price of $80 /yd3 can be assumed for pumped in place
lightweight fill. Rigid foam blocks are another lightweight fill alternative. The foam
blocks are considerably lighter than the pumped in place light weight fill, with unit
weights ranging from approximately 1 pcf to 2 pcf. The foam blocks typically come in
dimensions of approximately 3 feet X 4 feet X 18 feet. From a structural standpoint,
both types of light weight fill are suitable for support of traffic and slab -on -grade
Toads. In our opinion, the ill proposed on the east and west ends of the generator
pad can consist of either th pumped in place fill or the foam blocks. If filling of the
void space below the gener for pad is planned, however, we recommend the use of
the relativelyi lighter foam blacks to reduce differential settlement of the utility conduits
at the entry ;point to the building. ECI can provide specific information on pricing,
local suppliers, and contractdrs, if requested.
The type of lightweight fill arid the method used to mitigate settlement in the fill areas
will ultimately determine hovly much settlement and downdrag loading to expect. In
general, however, if a pumped in place lightweight fill is used to mitigate settlements,
we would expect settlement of about 0.75 inches to 1.5 inches over the life of the
project. Ttae new and xisting piles could experience downdrag loads of
approximately, three tons as a result of the lightweight fill placement. If the relatively
light weight foam blocks are used in the fill areas, we would expect post- construction
settlements of less than 0.75 nches, and downdrag Toads of less than one ton.
Tank Excavation
1'U. 4140 I. 1L/ [.
We understand installation of underground storage tanks is planned along the east
side of the proposed generato pad. Installation of the tanks will require an excavation
of approximately fifteen (15) tb eighteen (18) feet in depth. In our opinion, due to the
loose soil conditions and shallow groundwater conditions, open cutting of the
excavation is not feasible. A shoring system consisting of cantilevered sheetpiles or
an internally braced sheetpile all are feasible alternatives for temporary shoring of the
excavation.

For design of the sheetpile shoring, an angle of internal friction of 32 degrees should
be used for the existing f II soils and native silt soils that will be retained by the
sheetpile wall. The existing fill soils generally consist of silty sand with gravel. A
traffic surcharge of one-hurldred pounds per square foot (psf) applied in a rectangular
distribution along the entire 'height of the wall should be included in the anal '
the restraining soils located along the embedded portion of the sheetpiles, ant internal
angle of friction of 30 deg ees should be used. Based on our review of the soil
conditions at the site, the soils anticipated along .the embedded portions of the
sheetpiles should consist of silt, sand, and .silty sand. Groundwater should be
modeled at a depth of six feet below the existing ground surface, and buoyant unit
weights should be assumed for the existing fill and native soils located below the
groundwater, table.
Based on our experience wi h cantilever sheetpile shoring, pile embedment depths of
1.5 to 2.0 times the shoring height are typical. Given the proposed excavation
depths, we estimate sheetpil lengths of approximately forty -five (45) to fifty (50) feet
will be necessary_ If a braced or tieback sheetpile shoring system is used, we
estimate sheetpile lengths of approximately thirty (30) feet will be necessary. Due to
the high groundwater table, pumping of the shored excavation will be necessary,
heave of the ,excavation bottom should be expected. The use of a woven geotext le
and rock ballast can be used `to help stabilize the excavation bottom. Pumping of the
excavation can be achieved t y the use of sumps or well points installed around the
excavation perimeter_ The rte of groundwater flow into the shored excavation is
difficult to predict, and will d Pend on groundwater levels at the time of construction.
Based on an ;excavation area of approximately forty (40) feet by sixty (60) feet, we
estimate groundwater flows f approximately forty (40) to eighty (80T gallons per'
minute (gpm) are possible. P

Due to the relatively high groundwater table conditions at the site, buoyant forces
acting on the tanks should be considered. We understand the tanks have a diameter
of approximately twelve (1F) feet. Based on a minimum six foot of soil cover over the
tanks, uplift of the tanks Should not be a problem. The tanks, however, should be
anchored to the concrete mat foundation that 'will be constructed at the bottom of the
excavation.' The weight of the mat foundation can then be added to the total weight
resisting uplift of the tank . ECI should observe the excavation to verify soil and
groundwater conditions, an 1 to observe the subgrade. conditions at the bottom
excavation. Based on our bservations of subsurface conditions, it is our op n n the
tanks will not require pile upport. The use of a woven geotextile and
however, may be necessary) along the excavation
n bottom to provide a stable rock subgrade
for the mat foundation. In our opinion long term settlement of the tanks will not
exceed one inch. ECI should review the design for the tank excavation and shoring.
The manufacturer of the tanks should be consulted with regard to minimum soil cover
over the tanks in heavy trucl areas.
Permanent Retainin
and Foundation Walls
Retaining walls, and found tion walls that function as retaining walls should be
designed to resist lateral ea h pressures from the retained soils, and any surcharge
loading. For 'walls designed o yield a minimum ,of 0.002 times the height of the wall,
lateral earth pressures can be calculated using an equivalent fluid with a unit weight of
thirty -five (35) pounds per cubic foot (pcf). For non - yielding walls, the equivalent fluid
pressure should be increased Ito fifty (50) pcf. The above lateral earth pressure values
assume horizontal backfill conditions and no hydrostatic pressures behind the wall.
The above lateral earth pressure values assume no surcharges. due to traffic, adjacent
foundations, construction Toads, or any other loadings. If surcharges are to apply,
they should be added to the above design lateral pressures. To account for traffic
surcharges, a; two foot soil surcharge can be included in the retaining wall design,
where applicable.
The walls should be provided with a perforated PVC drain pipe and backfilled with a
free - draining material. The free- draining material should extend at least eighteen (18)
inches behind the wall. As arr alternative, a sheet drain such as Mira -Drain 6000 or
equivalent can ibe used in lieu f the free draining backfill described above.

Seismic Des! n Considerations
The Puget Sound region is, classified as Zone 3 by the Uniform Building
Code
The largest' earthquakes Inl the Puget Sound region have been subcrustal(iintra v Blate)
events, ranging in depth from fifty (50) to seventy (70) kilometers. Such deep events
have exhibited no surface faulting. Weaver and Shedlock (1989) researched the
probable or known source areas for the crustal, intraplate, and subduction zone
earthquakes in the Washington and Oregon area. Crustal and intraplate earthquakes
are the only events in Washington and Oregon in which there is a historical record.
Shallow crustal earthquakes occur within the North American Plate, and typically do
not exceed focal depths of approximately 20 kilometers. Intraplate earthquakes occur
in the subducting Juan de Fuca plate, and ,typically occur below depths of 40
kilometers. ;The subductionl zone earthquake, in which there is no historical record in
the Washington and Oregon; area, would have its source along the interface between
the North American Plate alnd the subducting Juan de Fuca Plate. Magnitude 8+
earthquakes; are thought to, be possible along this interface, and would occur a
depths of approximately 50 to 60 kilometers (Weaver and Shedlock, 1989). at
The UBC Earthquake regulations have established a series of soil profile types that are
used as a basis for seismio design of structures. Based on the encountered soil
conditions, it is our opinion that soil type SE from Table 16 -J of the 1997 UBC should
be used for design.
Liquefaction is a phenomenon in which soils lose all shear
time during an earthquake. 1The effects of liquefaction Smay befo large short
t alr'and of r
differential settlement for structures with foundations founded in the liquefying soils.
Groundshaking of sufficient duration results in the loss of grain -to -rain contact and
rapid increase in pore water pressure, causing the soil to behave a a fluid for short
periods of time.
To have potential for liquefaction, a soil must be cohesionless with a grain size
distribution of a specified range (generally sands and silt), it must be loose to medium -
dense; it must be below the groundwater table; and it must be subject to sufficient
magnitude and duration of groJndshaking.

Based on thI e soil and grouhdwater conditions observed at the site, it is our opinion
that the site has a moderate to high susceptibility to liquefaction. Pile support of the
structure will help mitigate the impacts of liquefaction related settlements to the
building. Settlement of lab-on-grade foundations and
pavements, however, is
possible. Structural su
ppoft of the building slab will help mitigate the impacts of
liquefaction Irelated settlem nts to the building slab. In our opinion, liquefaction
related settlements could be in the range of two inches to six inches, and would not
occur uniformly across the s te.
Structural Slabs
Structural slabs can be supported on existing or new structural fill. Loose or unstable
subgrade soils should be st bilized prior to construction of the slab. The use of a
geotextile and crushed rock I can be considered for stabilizing the subgrade soils, if
necessary. A four -inch capillary break consisting of a free draining
or gravel with Tess than 4 percent fines (percent :passing the #200 sieve, based on the
minus 3 /4-inch fraction) should be placed below the slab. In areas where slab
moisture is undesirable, a vapor barrier such as a 6 -mil plastic membrane can be
placed beneath the free draining sand or gravel. 'ECI should observe the slab subgrade
prior to placing the slab capillary break material.
As
previously discussed, tkie existing structural slab will be removed during
construction. 1In the event the subgrade below the structural slab has subsided, filling
may be necessary to re- establish the subgrade elevation. ECI should be contacted if
fills of greater?than six inches are necessary to re- establish the subgrade.
Site Drainage
The site must be graded such that surface water :is directed away from the buildings.
Water must not be allowed to stand in construction areas. During construction, loose
surfaces should be sealed by compacting the surface to reduce the potential for
moisture infiltration into the s ils. Interceptor trenches should be provided along the
perimeter of excavations to intercept groundwater seepage before it enters the
construction area, where necessary,

Heavy groundwater seepage conditions should be expected in excavations that are
advanced below a depth 6f approximately six feet. Temporary dewater'
excavations may be necesary. Ing of deep
Perimeter footing drains should be installed to help reduce
infiltration.: A typical footing drain detail for the perimeter footingspor grade for
beamstiis
provided on Plate 3. Under no circumstances; should roof downspout drain lines be
connected to the footing or foundation wall drain systems. All roof downspouts must
be separately tightlined to d scharge.
Excavations' and Slopes
The following information i provided solely as a service to our client. Under no
circumstances should this information be interpreted to mean that ECI is assuming
responsibility for construction site safety or the contractor's activities; such
responsibility is not being implied and should not be inferred.
In no case should excavation slopes be greater than the limits specified in local, state,
and Federal ;safety regulations. Based on the information obtained from our field
exploration, the soils observed would be classified as Type C by OSHA. As such,
temporary cuts in these so Is should be sloped at an inclination no steeper than
1.51-1:1V (HoEizontal: Vertical) ECI should observe the excavations to observe soil and
groundwater conditions, anc) verify the OSHA soil type. ECI should review the
temporary slope and grading ;plan and observe Conditions during excavation to verify
soil and groundwater conditions. If temporary slopes cannot be constructed in
accordance with OSHA guide ines, the use of temporary shoring may be necessary.
Permanent cut and fill slopes should be inclined no steeper than 21-1:1V. Cut slopes
should be observed by ECI during excavation to verify that conditions are as
anticipated. Supplementary recommendations pan then be developed, if needed, to
improve stability, including flattening of slopes or installation of surface or subsurface
drains. In any case, water should not be allowed to flow uncontrolled over the top of
slopes.
Permanently exposed slopes should be seeded with an appropriate species of
vegetation to reduce erosion and improve stability; of the surficial layer of soil.

If rockeries are planned at tale site, the construction should be in accordance with the
Associated :Rockery Contractors (ARC) Guidelines. Rockeries are erosion control
features, and are not intended to function as retaining structures. ECI should observe
excavations imade for rockeries, and periodically observe the rockery construction. In
areas where rockeries are Placed in front of fills, the use of geogrid reinforcement
within the fills may be necessary_ ECI can provide recommendations for reinforced
earth fills, if necessary.
Utility Trench Backfill
Based on the soil condition's encountered at the time of our exploration, remedial
measures may be necessary for support of utilities located below the elevation of the
existing fill soils. A woven g, otextile and rock ballast can be used to provide support
for utilities where weak soils are present along the trench subgrade, Below a depth of
approximately six feet, heavy groundwater conditions should be expected in the
trench excavation. In our opinion, utility structures and vaults that are not advanced
below a depth of approximately six feet will not require any special consideration
regarding buoyancy. Utility installations that are advanced below a depth of
approximately, six feet should be assessed with regard to settlement of the trench
backfill and buoyant forces acting on the utility structures. In our opinion pile support
of utilities will not be necessary. The use of lightweight backfill, however, may be
necessary for ,the deeper utilit' installations, such as sewer.
Utility trench backfill is a primary ary concern in reducing the potential for settlement
pavement areas. It is important that the utilities be adequately supported d in in
bedding material. The material should be hand tamped to ensure sl en the
around the haunches of these structures. Fill should be carefully placed and prov
to about twelve (12) inches above the crown :of the pipe or tanks before heavy
compaction equipment is brought into use. The remainder of the backfill should be
placed in lifts having a loose thickness of less than twelve (12) inches. A typical
trench backfill section and compaction requirements for Toad supporting and non -load
supporting areas is presented on Plate 4.

Pavement Areas
The adequacy of site pavements is related in part to the condition of the underlying
subgrade. To provide a properly prepared subgrade for
pavements, the subgrade
should be treated and
prepared as described in the Site Preparation and Genera/
Earthwork section of this reiiort. This means at least the top twelve (12) inches of the
subgrade should be compacted to 95 percent of the maximum dry density (per ASTM
D- 1557). Its is possible that some localized areas of soft, wet or unstable subgrade
may still exist after this process. Therefore, a .greater thickness of structural fill or
crushed rock may be needed, to stabilize these localized areas.
The following pavement sect on for lightly- loaded areas can be used:
• Two inches of asphalt concrete (AC) over four inches of crushed rock base
(CRB) material, or
• Two inches of AC oven three inches of asphalt treated base (ATB) material,
Heavier truck: traffic areas w II require thicker sections depending upon site usage,
pavement life; and site traffic. As a
considered for, truck - trafficked areas: general ;rule, the following sections can be
• Three inches of AC over six inches of CRB, or
• Three inches of AC covet four and one -half inches of ATB.
These pavement thicknesses rinay be modified based on anticipated traffic Toads and
frequency.
Asphalt concrete (AC), aspha$t treated base (ATB), and crushed rock base (CRB)
materials should conform to WSDOT specifications. All rock base should be
compacted to at least 95 percelnt of the ASTM D -1557 laboratory test standard.

Our recommendations and conclusions are based on the site materials observed,
selective laboratory testing Viand engineering analyses, the design information provided
to us by you, and our experience and engineering judgement. The conclusions and
recommendations are professional opinions derived in a manner consistent with that
level of care and skill ordinarily exercised by other members of the profession currently
practicing under similar conditions in this area, No warranty is expressed or implied.
The recommendations submitted in this report are based upon the data obtained from
the exploratory borings. Soil and groundwater conditions between borings may vary
from those encountered. The nature and extent of variations between our exploratory
locations may not become evident until construction. If variations do appear, ECI
should be requested to reevaluate the recommendations of this report and to modify
or verify them in writing prior to proceeding with the construction.
Additional Services
We recommend that ECI be retained to perform a general review of the final design
and specifications to verify that the earthwork and foundation recommendations have
been properly interpreted and implemented in the design and in the construction
specifications.

We also recommend that ECI be retained to provide geotechnical services during
construction. ;This is to obse ve compliance with the design concepts,
or recommendations and to allow design changes in the event subsurface conditions
differ from those anticipated I prior to the start 'of construction. We do not accept
responsibility for the perforntiance of the foundation or earthwork unless we are
retained to review the construction drawings 'and specifications, and to provide
construction observation and testing

been used in other projects to assist in meeting the noise standards in the Tukwila
Municipal Code.
2. The generators are required to meet the City's noise requirements when they are
being tested. The generators are not held to the noise standards in an emergency
situation where all of the generators would be running at the same time.
3. As part of the SEPA Planned Action, the following specific information is needed (a
copy of this information will also need to be submitted as part of the building permit
application):
• Provide a generator testing schedule that includes the number of generators to be
tested simultaneously, hours of testing and the duration of the tests and the
frequency (weekly, monthly etc.)
• Provide information on how the mechanical equipment on the roof will meet

During Construction, An all- weather access required to within 150' of the building.
No occupancy allowed prior to approval and inspection by Fire and Building Departments.
Adequate addressing is required. Fire Department will assign. Number size will be determined by setback
of building from roadway. (4" high numbers are minimum size)
Designated fire lanes may be required. (To be established at time of occupancy.)
Special Fire Department permit will be required for storage of hazardous materials per UFC Article 64
regardless of quantity of acid. Article 64 UFC will determine a hazardous use. According to Article
64, we do not have a Hazardous use governed by Article 80 since no individual battery contains over
20 gallons of acid. Two exits are not required and whole room acid containment is not required.
Fire Department access is required to within 150' of any portion of an exterior wall of the first story. Fire
Department roads in excess of 150' require turn around. Minimum width is 20'.
