INFORMAL ESA CONSULTATION
For Impacts to Listed Species
Associated with the
Renton Village Storm System Improvement Project
In the
City of Renton
(Updated June 14, 2006)
1. Proposed Activity:
The proposed project involves construction of a new stormwater drainage system
and outfall to serve the Renton Village Shopping Center to replace the existing
42- and 48-inch storm system. The purpose of the project is to replace the failing
48-inch corrugated metal pipe, and increase the capacity of the stormwater system
to convey the peak flow from the 25-year, 24-hour storm without upstream
flooding. The new stormwater system will be approximately 600 to 700 feet long
and will consist of two parallel pipes of equal or different sizes, a box culvert (8
foot x 4 foot), or some combination of these systems and sizes. The new outfall
will be constructed at the same location as the existing outfall. The Surface
Utility's engineering consultant is currently performing hydraulic analysis and
pipe design.
The project area is currently used as public and private streets, parking lots, and
businesses. The private property uses on the site where the creek and outfall are
located include an office building and parking lot. The private uses will not
change as a result of the project.
An area of trees and shrubs approximately 40 feet wide by 30 feet long will be
removed to construct the new stormwater system outfall. Vegetation in the area
consists of 4- to 8-inch diameter cottonwood trees and small shrubs. This area
will be cleared to install the outfall at the end of the new stormwater system. A
new layer of riprap and/or soft gabions will be installed to protect the banks
around the end of the new storm system.
1. The proposed storm system improvements may require the following
permits from the City of Renton:
• Land Use Permit Master Application and Environmental Checklist;
• Exemptions for Critical Areas, which may include;
o Geologic Hazard Area
o Flood Hazard Area
Informal ESA Consultation City of Renton
Renton Village Storm System Improvement Project Page 1
o Tree cutting and land clearing.
2. This Biological Evaluation is being prepared in the event that the Corps of
Engineers requires a Clean Water Act, Section 404 Permit for installation
of the new storm system and outfall, including placement of riprap, and
dredging or filling of the creek, at the outfall location.

98109, Barry Baker
6. Project Name: Renton Village Storm System Improvement Project
7. Location: NE corner of Section 19, Range 5 East, Township 23 North, in the City
of Renton, King County, Washington: Latitude 47°28' 16" North, 122' 13'00"W
8. Description of Work:
The new storm system will be located in the southern portion of the Renton
Village Shopping Center Complex. It will start in the street on the east side of the
Thriftway Grocery Store and will run to the southwest into South Renton Village
Place, and the parking lot west of the One Renton Place Building. It will end at
the open channel along the south side of Renton Village at or near the existing
storm system outfall.
The new storm system will be constructed in City ROW and utility easements that
have been obtained from the private property owners. The new storm system will
be constructed below ground. The existing streets and parking lots will be
restored once construction is complete. About 1,400 to 2,000 cubic yards of soil
may be excavated and replaced with backfill for construction. The Contractor
will supply backfill from a licensed gravel pit or source.
9. Construction Techniques:
Machinery (types
• Large front-end loader
• Crane (for lifting pipe/box culvert into place)
• Large backhoe or excavator (stormwater outfall removal)
Hand:
Pneumatic and hand powered drills and wrenches for installation of culvert
10. Permit Authorization Requested: NWP 3, Potentially NWP 17, NWP 43
11. Listed Species Present:
• Puget Sound chinook salmon, Oncorhynchus tshawytscha: Threatened:
Significant runs of chinook salmon inhabit the Green River system and use the
waters downstream of the project area for transportation, rearing and
Informal ESA Consultation City of Renton
Renton Village Storm System Improvement Project Page 2
acclimation to changes in salinity during migrations. A large pump station
downstream on Springbrook Creek is an impediment to anadromous salmonid
migration. However, according to Larry Fisher, Washington State Depart of
Fish & Wildlife Habitat Biologist for Southern King County, salmon present
in the Green/Duwamish system, including Puget Sound chinook, are able to
ascend past the pump station. From Springbrook Creek there is about 0.9 mile
of piped storm system below 405 downstream and the project area that is
paralleled by an open wetland area. The Priority Habitats and Species Map
prepared for this project on June 7, 2006 indicates that anadromous fish do not
ascend culverts downstream of 405 to within one half mile of the project area.
Larry Fisher indicated that salmon are occasionally able to ascend past these
culverts to just below the project area, but they are not known to ascend into
the project area.
Puget Sound bull trout, Salvelinus confluentus: Threatened:
Puget Sound bull trout and Dolly Varden may forage in the Duwamish
Waterway and lower Green River. Bull trout are not likely to spawn and rear
in this system because Howard Hansen Dam blocks access to potential
spawning habitat in the upper watershed. Further, the long piped storm system
and the pump station downstream are significant impediments to bull trout
passage in the system.
Puget Sound/Strait of Georgia coho salmon, O. kisutch: Candidate:
Significant runs of coho salmon are present in the Green/Duwamish system.
These fish utilize the waters downstream of the project area for transportation,
rearing and acclimation to changes in salinity during migration. Like bull trout
and chinook salmon, Puget Sound/Strait of Georgia coho may be able to
access the lower end of the project area, but they are not known to ascend the
culverts into the work area.
• Puget Sound Steelhead, O. Mykiss: Proposed:
Puget Sound steelhead are present in the Green/Duwamish River System and
are as capable of ascending to areas similar to those reached by chinook and
coho in the system downstream of the project area. Puget Sound steelhead
were proposed for listing as Threatened on March 29, 2006.
Critical Habitat for Puget Sound chinook salmon and Puget Sound bull
trout: The nearest formally designated critical habitat for Puget Sound
Chinook salmon and Puget Sound bull trout is located on the Lower Green
River and in the Duwamish Waterway approximately 15 miles downstream of
the project area. Pump stations, the long piped storm system and inconsistent
waterways above the pump stations limit the value of habitat in the
Springbrook Creek and Rolling Hills Creek, downstream of the project area.
Informal ESA Consultation City of Renton
Renton Village Storm System Improvement Project Page 3
12. Listed Non -Fish Species Present:
• Bald eagle, Haliaeetus leucocephalus: Threatened:
According to the Priority Habitats and Species Map prepared for this project
by WDFW on June 6, 2006, there are no bald eagle nests within one mile of
the project area. Foraging bald eagles may be present along the
Green/Duwamish and could follow Springbrook Creek into the project
vicinity, especially during the winter months. Heavy traffic along Grady Way
and in the shopping center generates enough noise to discourage use of the
discourage use of the area by bald eagles. The limited fisheries resources
present in the project area further reduce the likelihood that bald eagles would
spend a significant amount of time in the project area.
• Marbled murrelet, Brachyramphus marmoratus: Threatened:
Marbled murrelets nesting within 60 miles of Puget Sound may utilize the
waters of Elliott Bay and Puget Sound while foraging for small fish. It is
possible, but not likely that they could occasionally forage on the
Green/Duwamish and its tributaries in the project area. It is more likely that
they would fly through the project area en route to feeding areas offshore, as
they generally forage in deeper waters. Noise generated by I-405 and Grady
Way and development in downtown Renton likely cause marbled murrelets to
avoid the project area.
Listed Species present in King County (USFWS King County Species List, 8-
2-04), but not in the project area:
• Canada lynx, Lynx canadensis: Threatened: Lynx occur in King County,
generally in areas above 4,000 feet in elevation.
Gray wolves, Canis lupus: Endangered, may occur in King County, but are
unlikely to be present in the urbanized Lower Green/Duwamish River area.
Grizzly bears, Ursus arctos = U. a. horribilis: Threatened, may occur in
remote regions of King County.
• Northern spotted owls, Strix occidentalis caurina: Threatened, occur in
King County, but not in the project area (Priority Habitats & Species Map,
WDFW 6-7-06).
13. Existing Environmental Conditions:
The Renton Village Storm System Project discharges to a section of Rolling Hills
Creek via a system of open channels and culverts, some of which are more than
one-half mile long. These culverts and stream sections drains to Springbrook
Creek, the Black River, and eventually to the Green/Duwamish River system.
Low flows and the length of these culverts restrict salmonid passage to the area
approximately one half mile south of I-405 under most conditions. The project
area is largely developed with office parks, car dealerships, restaurants and
shopping centers.
Informal ESA Consultation City of Renton
Renton Village Storm System Improvement Project Page 4
The Green/Duwamish river system was diked in the early 1900s to protect
surrounding farmland and urban/industrial development. The Green/Duwamish
(downstream of the Black River confluence) is largely channelized and dredged to
facilitate navigation. Upstream of the confluence diking continues well beyond
Allentown (near Tukwila), but dredging for navigation ends and the streambed
exhibits a more natural meander pattern within the floodplain. River conditions
are largely glide with a few riffles upstream, and slower moving reaches with still
oxbows downstream. Tidal influence extends upstream to about Allentown.
Substrate in the project area is largely gravel with some mud and sand present.
Downstream in the Duwamish Waterway, substrate is dominated by mud,
especially in still reaches and off -channel oxbows. The Lower Green River and
Duwamish Waterway provide transportation and rearing habitat and allow
salmonids to acclimate to changing salinities during migrations.
Patches of natural riparian vegetation dominated by cottonwoods, willows and
alders line the Green River. Similar patches provide shade and detrital input to
Springbrook Creek and Rolling Hills Creek in places. Springbrook Creek lies
lower than the Black River channel and must be pumped into the Black by a large
pump station, which restricts salmonid migration into and out of the system under
certain conditions. According to Larry Fisher, WDFW Habitat Biologist for the
area, salmon are occasionally able to ascend the system to the lower end of the
Renton Village Parking Lot, but are not known to ascend the culverts into the
project area.
Flood Control & Pump Stations downstream:
The Green River Flood Control Zone District operates two pump stations, the
Black River Pump Station and Tukwila Pump Station, constructed by U.S. Soil
Conservation Service in 1970s. A third, the Segale Pump Station, was constructed
by the District in 1997. The Black River Pump Station regulates flow of water
from the Black River drainage basin into the Green River and serves to block high
flows from the Green from flooding up into the Black River and Springbrook
Creek, and the Earlington Industrial Park in Renton. A fish passage bypass has
been incorporated into the design of the Black River Pump Station, allowing most
species present in the Green and Black Rivers access to upstream habitat.
However, long culverts and pipes and inconsistent flows and land coverage limit
the value of habitat upstream of the pump station and downstream of the Renton
Village Project Area.
Conditions Downstream of the Project Area:
Approximately 650 feet downstream of the existing culvert outfall in the Renton
Village parking lot, the creek channel drains to a 48-inch pipe and a concrete weir
that allows high flows to bypass into a 132-inch culvert. These two culverts
convey flow approximately '/4 mile under the I-405/SR167 interchange to a
channel adjacent to the Panther Creek wetland on the east side of SR167. During
high flow conditions, this channel can overtop into the Panther Creek wetland.
Informal ESA Consultation City of Renton
Renton Village Storm System Improvement Project Page 5
The channel discharges into a piped system in SW 19`h Street for approximately 1/4
mile to Springbrook Creek. Springbrook Creek flows for approximately 1.5 miles
to the Black River Pump Station, which pumps into the Green/Duwamish River
system. A bypass channel has been constructed to provide passage for
anadromous salmonids. The Duwamish River discharges to Elliot Bay/Puget
Sound at Harbor Island in Seattle approximately 15 miles downstream of the
Black River Pump Station (See Figure X).
14. Effects Analysis:
Primary Direct Impacts:
Stormwater System Replacement
The Renton Village Stormwater System drains into Rolling Hills Creek and
eventually to Springbrook Creek. Construction of the stormwater conveyance
improvements will have the potential for adverse impacts to water quality in this
system; primarily turbidity generated by ground disturbance associated with
stormwater pipe removal and replacement. Construction will avoid and minimize
potential impacts to water quality by implementing BMPs for sedimentation and
erosion control. Water quality in the Black/Duwamish River downstream is not
likely to be impacted, as silt fences will be placed between work areas and the
Creek. Water quality in the Black and Duwamish Rivers downstream of the Black
River Pump Station will not be affected. The in -water work window for the
project area extends from June 1 to September 30 (Personal communication with
Larry Fisher, WDFW 6-14-06).
Work near Rolling Hills Creek may be conducted between June and September
30 using a large backhoe or excavator. The new stormwater pipe would be
installed and all or part of the existing pipe would be removed from the site and
disposed of at an approved facility. The most significant construction impacts
would be noise and potential sedimentation and erosion associated with removal
of the existing pipes and culverts. Construction Best Management Practices
(BMPs) for control of sedimentation and erosion will be implemented to
minimize potential for adverse impacts to water quality and fisheries habitat in
Rolling Hills Creek and Springbrook Creek. Water quality downstream in the
Black River, Green River, and Duwamish Waterway will not be affected due to
the distance from the work area and physical separation of those systems.
Riprap and Bank Stabilization
Small amounts of riprap and/or small gabions will be installed to protect the
stormwater outfall and creek bank from erosion. The disturbed area around the
new outfall will be replanted with vegetation. This work will occur during the in -
water work window and construction BMPs for control of sedimentation and
erosion will be implemented to minimize potential for adverse impacts to water
quality and fisheries habitat downstream.
Informal ESA Consultation City of Renton
Renton Village Storm System Improvement Project Page 6
Indirect Effects
Indirect effects associated with the proposed project would be limited to potential
for spills of fuels, coolants and lubricants from construction machinery associated
with the proposed work, or from automobile accidents that could occur in the
adjacent street or parking lots during construction activities. Construction
equipment will be properly flagged, and work areas and temporary traffic control
measures will be properly marked to minimize traffic disturbance.
15. Determination of Impacts to Species Protected under the Endangered Species
Act:
Puget Sound Chinook salmon, Puget Sound bull trout, Puget Sound steelhead
and Puget Sound/Strait of Georgia coho salmon:
Potential impacts to chinook salmon downstream of the project area associated
with removal of the existing Renton Village Stormwater System and the
installation of a new pipes and an outfall to Springbrook Creek would be limited
to potential damages to fish associated with added turbidity in the water. Because
Springbrook Creek must be pumped up to the Duwamish River, potential for
adverse water quality and fisheries habitats associated with the proposed Renton
Village Stormwater Improvement Project will be limited to the potential dropping
of construction materials into the creek, and accidental release of fuels, lubricants
or coolants from construction vehicles. The in -water work window for the project
area extends from June 1 to September 30 to avoid high water conditions. Terms
of the Hydraulic Project Approval will be implemented, so the potential for
adverse impacts to these anadromous species is negligible or discountable.
Therefore, removal of the existing Stormwater System in Renton and replacement
of the old pipe and outfall will have no effect on Puget Sound chinook salmon
and Puget Sound bull trout populations and their designated critical habitat
present in the Lower Green/Duwamish River 15 miles downstream of the project
area.
The proposed project will not jeopardize the continued existence of Puget Sound
steelhead. In the event that Puget Sound steelhead are listed as threatened in the
future, operation of the proposed storinwater system improvement will have no
effect on this species.
• The proposed project will not impact populations, individuals or suitable
habitat of Puget Sound/Strait of Georgia coho salmon. In the event that Puget
Sound/Strait of Georgia coho salmon are listed as "Threatened" in the future, the
proposed improvements will have no effect on this species.
• Bald eagles
The Priority Species and Habitats Map prepared for this project by the Washington
Department of Fish and Wildlife on June 7, 2006 indicated that no known bald eagle
nests lie within one mile of the project area. Wintering bald eagles forage along the
Green River during the winter months (November through February) but are unlikely
Informal ESA Consultation City of Renton
Renton Village Storm System Improvement Project Page 7
to utilize the project area due to noise associated with heavy traffic and the limited
potential for fisheries resources in the area. Therefore, the proposed replacement of
the stormwater pipe system and outfall will have no effect on bald eagles foraging
downstream of the project area.
Marbled murrelets, Canada lynx, Grey wolf, Grizzly bear and Northern
spotted owls:
According to the Priority Species and Habitats Map prepared for this project by
WDFW on June 7, 2006, there are no known marbled murrelet or northern spotted
owl nesting areas within one mile of the project area. Further, it is not likely that
these species would forage in the project area due to noise associated with heavy
traffic on I-405 and along Grady Way. Canada lynx are generally found above the
4,000-foot elevation, and grizzly bears and gray wolves are generally restricted to
more remote areas in the North Cascades. Therefore, implementation of the
proposed project will have no effect on marbled murrelets, northern spotted owls,
Canada lynx, grizzly bears or gray wolves.
16. Work window for construction:
• According to Larry Fisher, work near Rolling Hills Creek may be conducted
between June 1 and September 30.
• Wintering bald eagles forage in the area from November 30 through February 28
and no work on this project will be conducted during this period.
• There are no bald eagle, marbled murrelet or northern spotted owl nests within
one mile of the project area, so no timing restrictions are required to protect these
species during their nesting seasons.
17. Conservation Measures:
• Provisions outlined in the Hydraulic Project Approval shall be implemented
during construction.
• Construction vehicles and equipment shall be equipped with spill containment kits
and construction personnel shall be trained in their use.
• Detours around construction areas will be properly marked and traffic will be
controlled to minimize potential for accidents and associated spills of hazardous
fuels, lubricants and coolants during construction.
• Silt fences, straw bales and sedimentation ponds will be utilized as necessary, to
preserve water quality and fisheries habitat in Rolling Hills Creek, Springbrook
Creek and the Green/Duwamish system downstream.

WASHINGTON DEPARTMENT OF FISH AND WILDLIFE
PRIORITY FISH REPORT FROM THE WASHINGTO14 LAKES AND RIVERS INFORA]ATION SYSTEM (WLRIS) DATABASE
FOR TOWNSHIP T23R05E, SECTION 19
Report Date: June 07, 2006
Information About The Fish Presence Report
The fish information in this report only includes information that Washington Department of Fish and Wildlife
(WDFW) maintains in a central computer database. This information only documents the location of important
fish resources to the best of our knowledge. It is not a complete inventory of the fish species in the state.
Fish are identified as priority by if they meet one of three criterion as listed in the Priority Habitats
and Species List. The list is available by contacting WDFW Priority Habitats and Species section at (360)902-
2543, or it is available on our web site at http://www.wdfw.wa.gov/hab/phspage.htm. To insure appropriate use
of this information users are encouraged to consult with WDFW biologists.
Streams with presence of priority anadromous and resident fish species from the WLRIS database are highlighted
on the accompanying map. Due to the complexity of displaying linear features individual species that utilize
each river reach are not distinguishable. If more species specific information is needed, users should request
individual species maps, digital data, or contact the WLRIS database manager.
State status information is not available in the WLRIS database for these species. Please see WDFW Species of
Concern List for current status. For a copy of this list, contact WDFW Endangered Species Section at (360)902-
2515, or it is available on our web site at http://www.wdfw.wa.gov/wlm/diversty/soc/soc.htm-

CONCLUSIONS AND BIECOi M NDATIONS
GENERAL
We recommend that the new structures be supported on piles: which are..
driven into the moderately competent: sandstone:., The lower floor slabs of
the new structures should also bel,pile-supported to eliminate the potential
for long-term 'differential settlement between >the slabs and the building:
frames.
SITE PREPARATION AND, .EARTHWORK
Site Preparation:. We recommend 'that all brush and sod be stripped from
building and new pavement ;areas<and wasted.. Ex„fisting asphalt pavement: can
be left in ,place: within 'the new building areas:, provided; that it. will not.
interfere with installation of piles and utilities; Existing asphalt `in new
pavement. areas can be left in place, provided; it is:broken into relatively;
small pieces (less than l footmaximum dimension) as necessary to proimote
drainage.:
The. existing- bank building 'fronting Grady Way will: likely be
demolished. Foundation elements,. :and slabs for this abandoned building
Fi7mc! oe.rec}s?ed p3�er si% ::. _. .. .. ...
G e o Engineers
After stripping demolition and void filling are complete, we recommend::
that pavement subgrade areas be proofrolled with heavy, :rubber '=tired.
c'.onstruction equipment if site preparation is done during prolonged dry
weather. if this work. is done during wet weather, the exposed :subgrade:
areas should be probed and all but lightweight construction equipment kept
off the subgrade. Any soft,. loose or otherwise unsuitable areas detected:
r•; should.be'recompacted;, if practical, or removed and replaced With. structural..
full. We. 'recommend that the probing and proofrolling of subgrade areas be
observed by a representative.of our firm to identify areas need:ng.'remedi:al.
work and to assess the adequacy of subgrade conditions:::
structural Fill: All new fill in sidewalk::and,.pavement areas should be:
placed as Compacted structural fill. The. -£ill should -be placed in
horizontal. lifts not :exceeding 10 inches in.loose thickness': and mechanically
r compacted to a fi,:nonyielding condition. Full placed in pavement areas:
l rmor inutility trenches within 2 feet of the finished subgrade surface should
be compacted to at least 95 percent: of the maximum dry- density determined
in accordance with ASTM b-1557: Fill placed in: -pavement areas: And utility
i trenches at depths greater than.2 feet below .the finished 'subgrade. 'shoul&
be compacted to. :at least 90 percent (ASTM D-1557). Fill placed in the:
j building areas need only be compacted. to the degree.: required for support of
! construction equipment and E6 construct floor slabs.
All structural fill. :material should be free. of debris,, organic,
contaminants and rock fragments larger than 6 inches:: Particle sitit 1drger'
I than 3 inches should be:.:.excluded., from the top 1 foot ;of. the fill-. The:
suitability- of material for use as structural fill will depend on the,
gradation and: moi"s.ture:. content of the soil. As the amount of fines:
(material.passink. No :20O.:sieve) increases, soul becomes itereasingly:more
sensitive;, to° small changes in- moisture content. :and adequate. compaction
j becomes .more difficult t6 achieve. We recommend, that structur. fill
,contain no more than, about, 5 percent fines.for placement in wet weather.
The percent fines can be higherfor placement in dry weather, providing :that
the fill: material is moisture -conditioned. as.; necessary for proper
-.- compaction. -
The existing fill pad in, the southern portion of :the new p_arkxng.garage

Appropriate..
We recommend that a representative:: from. our firm observe the placement
and compaction of structural fill. An.adequate number. of in -place density
tests should be performed as the fill is being placed to determine if the
required degree of compaction is being achieved.
Fill.Settlement'fWe understand.:that .on the, order of 2 to S feet of
fill will be placed in building and pavement areas: -to achieve. the desired
grades;, This fill :will be underlain by -variable thicknesses.. of soft
compressible soils which will settle under ttie weight of the fill. We
estimate that 3 feet of fill will result in. about 3 to 6 inches of
t'
settlement. 'Smaller or larger" thicknesses of fill will cause
r
proportionately lesser or greater magnitudes of settlement. We. expect that
a majority of this rsettlement. (e.g.,,. on the order of 50 to 60 percent) will
occur, within two months of: fill placement. However.: a significant amount
of settlement (e..g., on the order of'40 to 50,:perc_ent): is likely to occur
over.a period of several years due to.the slow rate of consolidation in the
peat layers. For, this re:as.on,. we ,recommend that, the; lower floors for the
i
new parking garage and the new office building be pipe supported:
:The potential effects; of fill inducedsettlements on: existing buried
utilities should 'be considered in design.. Poten"tal 'effects of -these,:

settlements on. the .proposed new facilities, are: addressed in later sections

We expect that these piles will penetrate 3 to 10 feet into the bedrock,
based on the results of the test pit program :and our borings.
Piles for: support of the lower floor' slabs in the buildings should.
extend .through the upper compressible deposits :to -either the medium dense:
to dense sand strata or into the bedrock: The thickness and density of the,
sand over -the bedrock varies- significantly across ;the site,•. however,, ;we

The allowable uplift capacity for the piles supporting the building
frame_ (.e., piles driven to refusal criteria appropriate for a 120-ton'
design downward load) may, be taken:as:.45 tons for short-term live.loads:such
;as wind.or seismic forces. This value. includes a factor. of: safety of. about
1.5,.and is: based on the results of the. uplift test.
The characteristics of pile::materials-and structural connections might
impose limitations an pile. capacities and should be evaluated by your
structural engineer, Appropriate reinforcing should be. provided in 'the
piles to accommodate bending: and. tension forces.. For example; a full-length
reinforcing bar should be installed iri each ;pile subjected !to uplift. Also,,
;reinforcing cages should be, provided in piles'subjected to lateral loads.
The above pile capacities apply to :single piles. If. <piles.;: within,
groups are spaced at least :'3; p le diameters on center..,: no reduct on.for pile
group action need be.made.:
There pis some risk from eccentric loading; associated with suppor€ing
building frame pile caps on single piles , Th ref re, we 'recommend that..
these naps: be supported on pile .groups :consisting: of two or more. piles:.
Pale Downdrag: Pile downdrag forces develop when surrounding
compressible soils settle :relative to a pile,. thus interacting with ,and.
adding: load to the piled.. We anticipate that 2' to 5_feet of fill .will be
placed over the building s>te.; ;For this amount of :fill, an allowance for
downdrag of 15 tons :should be made for the 14-inch driven grout piles;. The
downdrag forces. should be added. to the nominal :design load for: the ,pile to.
compute the total load acting :on the .pile.
Settlement:: We: estimate that the settlement...of driven, grout piles:,
designed and installed as. recommended, will be on the order of inch°or:
less'. Most of this settlement will occur rapidly- as loads: are applied.

The elevation and characteristics of the bedrock vary considerably
across the site. It is important that :each pile; _peasetrate..into.the desired.
bearing material. Therefore, we recommend that pile installations be:
monitored by a member of:',our staff,. to; observe ,installation procedures,
record pertinent data, and evaluate the adequacy of individual ,pile
penetrations.
FLOOR SLAB SUPPORT
The lower floor slabs should be: supported on: piles because;.'of the
potential for significant long-term differential settlement both between a'
soil: -supported slab and::. the pile -supported building frame:, and across the
building:. Provisions,should be made,under.the floor-slab.`ao vent potential.
accumulations of methane ;gas and to .:protect. the slab from dampness:. For:
;this., we recommend that a 6-inch'-thick. blanket'of, coarse sand or ,gravel .be
placed beneath the slab. In addition, a, vapor barrier should be placed
be* tween. the blanket and ::the floor, slab:: The sand or gravel blanket ishould,
be. vented: to. the outside, using perforated drain pipes spaced at 60- to
80-foot intervals.

To minimize postcons.truction settlements due to fill placement, filling
should be accomplished at the onset of construction and the construction of
on -grade facilities (e:g., entries, sidewalks, buried utilities and
pavements) delayed:as long as possible.
PAVEMENTS:
Pavement subgrade areas should be prepared as recommended under SITE
PREPARATION. AND EARTHWORK.
We recommend that.:the design pavement :section .in automobile parking
-areas consist of 2 'inches. of'Class B asphalt concrete,. 4'inches.:of `crushed.
rock base course and an appropriate thickness of clean pit run sand and:
gravel. In truck and heavy traffic areas,- ;the design pavement section
should ,consist of 3 inches. of Class B asphalt concrete;, b inches of crushed
rock "base .course., and, an appropriate thickness of ..glean pit run sand and.
gravel.

FIELD EXPLORATIONS AND L&BORATORY TESTING
FIELD EXPLORATIONS
Subsurface conditions at the project site were explored by drilling
eight borings at the 'locations shown in Figure 2-. Exploration locations
were ,measured in the 'field by, taping from.existing.site features. Figure
2 also shows the. locationof'a previous boring:{B4-1) which. was 'drilled at
the "site in 1986 by.our firm.
The borings were drilled 'between ;October .22; .and 30, 1991 to depths.
ranging,. -kom 44 to 72 feet. below existing grade. These borings were
advanced using a truck -mounted,: continuous -flight, hollow-stem..auger drill.
Representative samples were obtained': of each soil and rock. type' encountered:
These. samples were obtained:,using a 2`,;4 inch -diameter, split barrel sampler:
The sampler was driven into the' `soil or rock using, a. 3,00-.p6urid hammer free
falling 30 inches. The number of blowsreguired to drive the, sampler: the
last '12,inches or other indicated distance is 'recorded :on' the: boring logs
The borings were continuously monitored by :a representative of our
