Scope of Work — Additional Services for Cultural Resources Site Delineation and
Geotechnical and Environmental Support
Duwamish Gardens
Prepared For:
Ryan Larson, the City of Tukwila Public Works Department
Project Description
The project involves design and permitting services for the construction of estuarine fish habitat on a 2.16
acre City owed site. A conceptual site plan has been developed by the WDFW and calls for the
excavation of 55,000 cubic yards of material to establish approximately 2 acres of shallow water mudflat
and marsh habitat and approximately 0.8 acres of uplands planted with native vegetation.
This extra services scope of work is to provide an Archaeological Site Delineation as requested by the
U.S. Army Corps of Engineers ("the Corps"), the lead consulting agency for compliance with Section 106
of the National Historic Preservation Act ("Section 106"). This extra services scope also includes
additional groundwater monitoring.
Task 1 — Administration
Administration tasks include meeting coordination, scheduling, contract administration and subconsultant
administration costs and expenses.
Task 2 -- Cultural Resources Site Delineation
Initial Cultural and Historical Resource Investigations (Task 2.2 of the Contract) has been completed. At
a meeting on July 12, 2012, it was determined by the Corps that further investigations and delineation of
cultural resources at the site would be required to make a Section 106 determination. Subsequently, ESA
Paragon Associates, in collaboration with the Corps and the Muckleshoot Tribe and other stakeholders,
prepared a site delineation plan, which proposes a series of trenches and test pits throughout the property
to ascertain the extent of cultural resources.
See Attachment A for a detail on this scope of services and products. J.A. Brennan Associates will
provide client — agency coordination, attend a site meeting and review ESA Paragon's Technical Report.
Task 3 -- Geotechnical and Environmental Support
Initial Hydrogeologic Assessments (Task 2.3.7 of the Contract) have been completed. Subconsultant,
Shannon &Wilson installed vibrating wire piezometers at three locations in order to measure fluctuating
groundwater conditions. Data was recorded between June and August, 2012. This additional service
request includes additional groundwater monitoring though the winter and spring 2013, when rainier
conditions are expected that could provide informative groundwater level data.
City of Tukwila Duwamish Gardens Scope of Work
See Attachment B for a detail on this scope of services and products. J.A. Brennan Associates will
provide client coordination and review of groundwater monitoring data reporting.
Assumptions
1. This scope of work does not include data recovery work or work associated with mitigation
requirements that may be determined by the Corps.

ARCHAEOLOGICAL TESTING PLAN — DUWAMISH GARDENS
Prepared by Chris Lockwood, Ph.D., ESA Paragon
At the direction ofthe US Army Corps of Engineers, ESA Paragon has developed this archaeological
testing plan for the City of Tukwila's Duwamish Gardens project. Azcbucokmiudourvoyaod
archaeological monitoring of geotechnical geoprobing suggests tha archaeological remains associated
with precontact site 45-KI-703 extend into the Duwamish Gardens Permit Area. The Permit Area also has
a Iengthy history ofuse as a farmstead and residence since the 1880s.
Archaeological testing is being conducted for the purposes of: 1) deline i the extent of archaeological
remains associated with archeological oitc45-KI'703, and 2) assessing the potential of these remains to
address research questions relevarit to 45-K1-703 as set forth by Blukis Onat et al. (2010:33'36). The
testing efforts will also be used to determine if there is a separat historic archaeological site related to the
historic farm.
FIELD METHODOLOGY
Testing will commence with mechanical trenching, followed by excavation of 8-10 controlled test units;
the exact number and location of test units will be determined based upon the results of trenching.
Trenching
ESA Paragon will direct excavation of 12-16 backhoe trenches across the Duwamish Gardens Permit
Area (Figure 1). Trenches will be 1.5 m wide x 1.5 m deep, and ofvariable length. Sediments will be
excavated in thin lifts, and spoils will be laid out for archaeological inspection. Trench walls will be
inspected, photographed, and stratigraphic profiles drawn. Opportunistic screening (l/8" mesh) and hand
sampling may be conducted in areas containing artifacts, features, or other cultural evidence.
Trenches will be oriented to evalua the stratigraphy that has developed from the river towards the higher
elevation riverbank in order to expose the greatest stratigraphic variability and to provide greater
environmental information. Because natural depositional units would be oriented paraliel to the river, the
trenches will be oriented perpendicular to expose these in cross section. Other trenches will be oriented
parallel to the river to test the hypothesis that there is a discernible change in stratigraphy as highlighted
in the organic matter testing.
One trench will be excavated to specifically investigate the depression in front ofthe bunkhouse building.
Test Units
Based on the results of trenching, ESA Paragon will hand excavate 8-10 test units in locations estimated
to have the highest potential to address research questions set forth in Blukis Onat et al. (2010:333-348).
Units will be 1 m wide x 1 m long, and of variable depth. Excavation will be conducted by natural
stratigraphic layer; natural stratigraphic layers thicker than 10 cm will be subdivided into arbitrary 10 cm
levels. Test units will extend to 1.3 m below ground surface or 30 cm beyond sterile, whichever is deeper,
and may require safety benching. Test unit walls will be inspected, photographed, and stratigraphic
profiles drawn. All material will be screened through 1/8" mesh; artifacts and samples will be collected
for analysis and curation.

EXPECTED DATA CATEGORIES
Prehistoric archaeological remains recovered during testing and data recovery at 45-IU-703 include flaked
stone and ground stone tools, animal and fish bones and shell, botanical remains, pollen, fire modified
rock, fire features, postmold, depressions/pits, and pebble/rock concentrations. The archaeological site is
characterized by organic-rich sand layers.
Historic archaeological materials in archaeological deposits may include: food bone from processing and
consumption of mammal (including domesticates), avifauna (including domesticates), and fish;
manufactured items (e.g., glass, ceramic, metal, wood) associated with domestic life within residences;
tools, equipment and/or materials associated with agriculture; and foundations, post molds, pits, privies,
oxidized matrices, and other soil stains associated with residential and agricultural use.
ARTIFACT AND SAMPLE COLLECTION AND PROCESSING
Artifacts encountered during Duwamish Gardens archaeological testing are planned for curation at the
Burke Museum of Natural History and Culture in Seattle.
Artifacts will be collected and bagged in inert polyethylene 4mil ziptop bags with exact proveniences
recorded. Artifacts will be transported to the ESA Paragon archaeological analysis laboratory for
description, photography, illustration, and analysis, and prepared for curation. Analyses will be
conducted concurrently with fieldwork. All analyses will be completed within 30 days of fieldwork.
45-KI-703 Testing Plan Page 2

ANALYTICAL TECHNIQUES
Analyses of artifacts and samples collected during archaeological testing at Duwamish Gardens will be
conducted for the purpose of assessing the potential to address research domains relevant to 45-KI-703 as
set forth by Blukis Onat et al. (2010:33-36). Ifinvestigations continue into data recovery, additional
analyses of materials collected during test excavation may be needed.
Lithic Artifacts
Lithic artifact classification would include assessment of materials used for stone tools, techniques used
to manufacture stone artifacts, and functions of stone tools based on use-wear patterns and traditional
formal typologies. Stylistic analyses of projectile yointouodotberteozporu|lvoenodivcutooctoolop,nvide
chronological information. (If investigations continue into data recovery, trace element or other sourcing
techniques may be used to estimate the source lithic raw materials, and to infer mechanisms that operated
in the economic system to obtain raw materials, such as long distance trade).
Mammal, Fish, and Bird Bone
Bone analysis would include weights and counts (NISP), identification to taxonomic class (e.g., fish, bird,
or , assessment of bone breakage and burning patterns to infer processing techniques and post-
depositional changes. (If investigations continue into data recovery, additional analysis may include
identification to lower taxonomic levels and demographic analysis (age/sex) to make inferences regarding
seasonality and diet).
Shellfish
Shellfish ana cis would include bulk weights, counts(NISP) and relative abundance of fragments by size
class (1", y7`, W" and 1/8`). (If investigations continue into data recovery, additional may
include identification of hinges and spines to lowest possible taxonomic level; measurement of hinge size
to estimate variation in sizes of shellfish collected over time; and estimation of hinge/shell weathering).
Botanical Remains
Botanical analyses would include bulk weights of material, and estimation of relative abundance of wood
versus other botanical remains. (If investigations continue into data recovery, additional analyses may
include identification of samples to lowest possible taxonomic level, estimation of seasonality, inferences
of kinds of activities associates with different botanical materials such as use for fuel, food, or
technology, and evidence for post-depositional disturbance of archaeological sediments).
Perishable Artifacts
Perishable artifac such as basketry or matting may occur in archaeological deposits. Field and laboratory
personnel would stabilize, clean, and store perishable ozatecbdo following standard archaeolo ioul
procedures. Analysis would include assessment of artifact function. (if investigations ons continue into data
recovery, additional analyses may include identification to lowest possible taxonomic level and
estimation of seasonality).
Fire Modified Rock
Fire mod fied rock would be analyzed, using a classification system including material type,
discoloration, and breakage patterns. Samples of fire modified rock from bulk samples would be
classified, measured, weighted and count d.
45-KI-703 Testing Plan Page 3
July 2012
Utilized Bone and Shell
A functional classification system will be used to categorize shaped bone and shell artifacts into types that
reflect probable uses, uses such as fishing (e.g., fishhooks and harpoons) and woodworking (e.g., chisels
and wedges).
Sediment
Soils data (e.g., soil pH, organic matter content, grain-size distribution, and other may be used
to infer past ge ic conditions and post-depositional processes.
Radiocarbon Analysis
Samples of charcoal, wood andlor shell may be analyzed by a professional radiocarbon dating laboratory
to provide age determinations for samples in radiocarbon years. AMS radiocarbon dating will be
preferred over conventional radiocarbon dating. Samples will not be aggregated as a method for
obtaining sample sizes sufficient for radiocarbon dating. Radiocarbon age determinations will be
calibrated to correct for temporal variation in atmospheric 14C. If shell samples are submitted for
radiocarbon analysis, additional age corrections may be required to account for variation in the carbon
content of marine water.
Thermoluminescence Analysis
Samples of fire modified roc may be analyzed at a specialized archaeological laboratory for
thermoluminescence analysis. Age determinations from thermolumin occoou analysis may be used to
provide independent chronological control to corroborate age determinations from radiocarbon analysis.
Historic Ceramics
Analyses of ceramics will include assessment of form and function, analysis of style and manufacturing
technique, and determination of manufacturer and date of manufacture through seriation and aiialysis of
makers' marks, stamps, or other evidence.
Historic Glass
Analyses of vessel glass and other "non-flat" glass will include assessment of form and function, analysis
of style and manufacturing technique, and determination of manufacturer and date of manufacture
through seriation and analysis of makers' marks, stamps, or other evidence. "Flat" or window glass will
be characterized (modern or historic), recorded, dimensions (area and thickness) recorded with an
estimate ofpanes, but not further analyzed. Ifpossible we will correlate the flat glass with a specific
building.
Historic Metal
Analyses uf metal artifacts will include assessment of form and function, analysis of style and
manufacturing technique, and determination of manufacturer and date of manufacture through seriation
and analysis of makers' marks, stamps, or other evidence.
Other Historic Artifacts
Other types of historic artifacts will be analyzed using generally-accepted methods as appropriate.
CURATION
Artifacts collected during archaeological test excavations at Duwamish Gardens will be curated at the
45-KI-703 Testing Plan Page 4
July 2012
Burke Museum of Natural History and Culture, in Seattle, WA, which has agreed to act as repository for
collections, records, ph and data from the Duwamish Gardens project. The collections from
2O05 excavations om45'8J'703 are curutedu¢ the Burke. Collections will be curat d to meet the Burke's
Curation Guidelines.
RESEARCH DESIGN
Archaeological testing is being conducted to det rmine the extent nature, and age archaeological remains
at Duwamish Gardens for the purpose ofassessing whether deposits have the potential to address and
provide new information regarding the foliowing research domains previously developed by Blukis Onat
ct al. (20lO:33'36; see scanned attachment) for 45-DJ-703:
Research Domain 1: Site Formation Processes
Research Domain 2: Resource Specialization
Research Domain 3: Environmental Enhancement and Settlement System Development
Research Domain 4: Artifact Types and Distributions, Trade, and Regional Contacts
Research Domain 5: Ethnographic Correspondence
Because the Duwamish Gardens archaeological testing will be conducted in proximity to historic
icultural and residential areas where there is th potential to encounter historic archaeological remains,
and because no historic research domain was developed previously, it is anticipated that an additional
research domain related to historic landuse will be developed, and archaeological testing results evaluat d
against this additional research domain. However, we expect that any historic archaeological remains will
be recorded as a separate site.
REPORTING
Reporting will occur afte analysis of fieldwork has been completed. A summary technical report wil
present all data from the archaeological testing, evaluate the potential for additional archeological
deposits and their ability to address the various relevant research domains. A site form updat for 45-KI-

451(1703 DATA RECOVERY REPORT
Data recovery excavations at 45K1703 dressed research domains outlined in the ARMT
(Blukis Onat et al. 2004:53-55). Research questions were adapted for the Su 4 dertlefital
Treatment Plan (LeTourneau and lukis Onat 2004b) (Appendix B). The five prehistoric
research domains considered: (1) environmental a, ptation and landform use; (2) resource
specialization; (3) environmental enhancement and settlement system development; (4) artifact
types and distributions, trade and regional contacts; and (5) ethnographic correspondence.
The research questions that were part of the dati recovery plan at site 45K1703 are itemized
below in the context of the five research domains. The complete text is provided in LeTourneau
and Blukis Onat 2004b (Appendix
Within each research domain, the questions are grouped by ic. Not all questions listed could
be addressed at 45K1703, nor are they exhaustive. They are suggestions of topics that might be
addressed at the site, not predictors of what would be found. Research questions that arose in the
course of investigations are presented and discussed in SECTION 15.

13. Data Recovery Management and Methods
Fieldwork safety and security, archaeol :ical excavation strategies, and laboratory processing
methods for data recovery investigations at site 451(1703 are detailed herein. The methods used
were based on those that had been oposed (LeTourneau and lukis Onat 2004b) (A ix 13).
Divergence from these methods was limited and resulted from field conditions that could not
have been anticipated. They are noted in the following discussion. Procedures for specific
analyses are included in ate SECTIONS that describe the respective analysis results and in
specialist appendices.
Overall staffing for data recovery investigations has been detailed in SECTION 1. The more
specific responsibilities assigned to different persons are indicated in the following.
3.3.1. Fieldwork Safety a Security
During the data recovery field excavations, the archaeological crew followed standard OSHA
safety regulations. Lucy F. Zuccotti acted as • AS safety officer. All Field Archaeologists and
supervisory staff wore safety vests as a preventive measure due to vehicular traffic on a nearby
driveway. Hard hats were worn when construction took place near the archaeological
excavations.
For site safety and security, the investigation area was surrounded with chain-link fencing
(Figure 15-d and Figure 17). The fence had a movable gate that was locked at night. Some crew
members lived at the Ray-Carrossino Farmhouse and provided informal site security during non-
working hours. Sound Transit assigned security guards to patrol the area during times when
archaeological work was not taking place.
Access to the investigation area was restricted to BOAS excavation personnel and occasional
visiting professional archaeologists and tribal representatives. Substantial wooden stairs were
built into the north and south walls of the excavation area to provide safe, low-impact access
(Figure 17 and Figure 18). Designated walking routes within the area of investigations
minimized impact by excavation personnel.

Subject: Duwamish Gardens Archaeological Site Delineation
Dear Mike:
www.paragonresearchnet
Attached is ESA Paragon's scope of work and cost estimate for the Duwamish Gardens Archaeological Site
Delineation for 45-K1-703. The scope (Attachment A) and cost estimate (Attachment 13) have been developed
based on the project approach set forth by USACE and the Delineation Plan prepared for the project.
The scope is phased to include a program of archaeological trenching (Task 2) with a follow-on program of
archaeological test excavations (Task 3). At the completion of Task 2, ESA Paragon will provide an interim
memorandum of results (Task 2.1), and, if requested, participate in an on-site meeting of stakeholders to
examine trench exposures (Task 2.2). Initi ion of Task 3 will be contingent upon a decision by the City to
continue with the project based upon Task 2 results. Please note that if the City determines it is not feasible to
continue with the project, we will still need to conduct tasks to document the site and prepare the artifacts for
curation. Further, even if we conduct test excavations, it is possible that additional investigations not included in
this scope of work may be determined necessary during consultation.
Although the cost estimate does not include the curation fees; current pricing for curation at the Burke Museum
may be found at http://www.burkemuseum.org/pub/09curation brochure.pdf. Based on the assumptions about
collection volume included in the cost proposal curation fees would be expected to be approximately $8,100.
Please contact me with any questions about this scope of work and cost proposal. We appreciate the opportunity
to participate in the creation of Duwamish Gardens.
Sincerely,
Chris Lockwood

Attachment A
Scope of Work
Duwamish Gardens
Site Delineation
Project Description: The City of Tukwila is proposing to enhance fish and riparian habitat along the right
(north) bank of the Duwamish River, in Tukwila, King County, Washington. Conceptual designs for the project
will require removal of existing buildings and structures, excavation, and alteration of vegetation. The USACE
has requested site delineation for 45-KI-703, a precon ct archaeological site that extends into the project Permit
Area, as well as other archaeological components that may exist within the Permit Area. ESA Paragon has
developed a Site Delineation Plan which outlines the procedures to be followed during site delineation activities.
Scope of Work: The Scope of Work to be conducted by ESA Paragon includes seven tasks:
Task 1. Client and Agency Coordination. Under this task, ESA Paragon will assist in coordinating
between City of Tukwila, US Army Corps of Engineers, the desi L4 team, DAHP, King County Historic
Preservation Pro am, d the interested tribes. ESA Paragon will also maintain project schedule and
budget.
Task 2. Arch ical Trenching. ESA Paragon will direct archaeological trenching of 17 trenches to be
completed by a City-supplied excavator. Trenches will be excavated to a maximum depth of 2 meters (6
feet), and may be internally stepped to provide safe access. ESA Paragon will document trenches using
standard archaeological methods. Opportunistic screening (1/8" mesh) and hand sampling may be
conducted in areas containing artifacts, features, or other cultural evidence.
Task 2.1. Interim Report of Results: ESA Paragon will provide a brief report of Task 2 results within
3 days of completion of Archaeological Trenching.
Task 2.2. Stakeholder Site Visit: ESA Paragon will participate in a site visit by stakeholders to
examine exposed trenches.
Task 3. Test Excavations. If, based on the results of Archaeological Trenching (Task 2), the City of
Tukwila opts to proceed with the project, ESA Paragon will then hand excavate up to 10 test excavation
units. Units will be 1 m wide by 1 m long, and will extend to 1.3 m below ground surface or 30 cm beyond
sterile, whichever is deeper, and may require safety benching. It is expected that test units will be oriented
along trenches. Test unit walls will be inspected, photographed, and stratigraphic profiles drawn. All
material will be screened through 1/8" mesh. Artifacts and samples will be collected for analysis and
curation.
Task 4. Artifact Analysis. Functional, typological, and preliminary chronological analysis will be
conducted for all artifacts. No specialists will be retained and no samples will be dated.
Task 5. Technical Report. ESA Paragon will summarize the findings of our work and recommendations
in a comprehensive Technical Report. If Task 3 is conducted, the Technical Report will include the results
of this work; otherwise, the Technical Report will only synthesize the Interim Report (Task 2.1) with
results of any Artifact Analysis (Task 4). The Technical Report will meet the current SHPO standards for
cultural resources assessment including making recommendations for mitigating or minimizing potential
adverse effects, if warranted by the results of the field work. ESA Paragon will submit a draft report (PDF
format) for review by the Client and selected stakeholders. Once comments are received, ESA Paragon

will submit four (4) bound copies and two (2) electronic copies (in PDF format) as the final deliverable.
Client will be responsible for distributing the technical report to ppropriate stakeholders.
Alternatively, if it is determined that data recovery will be conducted as mitigation to enable to project to
proceed, the Technical Report would be prepared and structured as a draft chapter for the antici ted Data
Recovery report, rather than as a stand-alone report. In this case, no hard copies will be distributed.
Task 6. Update Site Form/New Site Form(s). ESA Paragon will complete an archaeological site form
update for 45-1(1-703, as required by DAHP. One new arc r% eological site forms will be completed if
historic-peri 4 4 components that are not temporally associated with precontact tion at 45-1(I-703 are
encountered during fieldwork.
Task 7. Curation Preparation. ESA Paragon will prepare records, photogr,,, s, and for curation,
meeting the Burke Museum's curation requirements; ESA Paragon assumes that project records,
photogra , and a will not exceed 20 linear inches of curation space. If test excavations are conducted,
and artifacts or samples requiring curation are collected, ESA Paragon will prepare artifacts/sainples for
curation, meeting the Burke Museum's curation requirements; ESA Paragon assumes that the collection
will consist of not more 300 unique catalog numbers, occupy not more than 4 cubic feet. This cost
estimate does not include Burke Museum euration fees.
110 h..
Deliverables: ESA Paragon will prepare an Interim Report of Results (Task 2.1), and draft and final Technical
Report (Task 5; see Data Recovery exception above) that meet DAHP standards. ESA Paragon will prepare an
archaeological site form update, and up to one (1) new arc ological site/isolate forms, as necessary. ESA
Paragon will prepare associated records (and artifacts/samples, if collected) to meet Burke Museum curation
standards.
Schedule: ESA Paragon will provide a schedule following receipt of a Notice to Proceed.
Assumptions:
• All work will be conducted under the provisions set forth in the Site Delineation Plan.
• Per the Site Delineation Plan, the focus of this work will be delineation of prehistoric archaeological site
45-1(1-703; one trench will be excavated to investigate a depression near the historic bunkhouse.
• ESA Paragon will not conduct tasks with aboveground resources under this work order.
• City will provide excavator and operator (3 days of trenching, plus 1 day of backfilling at completion of
fieldwork); excavator to have 3-4 foot wide, smooth/"ditch" bucket (no teeth), and be capable of
excavating to minimum of 2 meters (6 feet) below ground surface. The excavator may be tracked or
wheeled, as available. City to furnish all safety posts/markers (e.g., pylons, candlesticks) to mark
trenches/test excavations.
• Trenches may be left open for stakeholder inspection until completion of Task 2 or Task 3, whichever
pertains. Archaeological deposits exposed in profiles or floors will be covered with geotextile cloth or
similar protective material prior to backfilling; an archaeologist will be present during backfilling.
• Under Task 2, 17 trenches will be excavated, requiring three (3) days of mechanical trenching.

• Under Task 3, up to 10 archaeolo cal test units will be excavated. Each test unit may take up to two (2)
days to excavate by two (2) archaeologists (4 person ys total), including any necessary benching.
• Task 3 will only be completed if directed by the City following completion of Task 2.
• Actual costs for Tasks 4-7 will vary based upon results of Task 2 and Task 3 (if conducted).
• Under Task 7, cost estimate assumes that project records, photographs, and ta will not exceed 20 linear
inches, and artifacts/samples will not exceed 300 unique c log numbers occupying not more than 4
cubic feet.
• One set ofeonsolidated comments on the draft Technical Report will be provided to ESA Paragon by the
Client.
Cost Proposal: ESA Paragon A s estimated the cost for the Duwamish Gardens Site Delineation based on the
hours and rate schedule included in Attachment B. ESA Paragon estimates t the sum of $71,846 will be
required to complete Tasks 1 through 7 as described above. Extra services will be initiated by ESA Paragon only
after agreement by both ESA Paragon and the Client concerning revisions to the scope of work and additional
compensation, if necessary. This scope and cost estimate does not include preparation of a Supplemental
Treatment Plan, or conducting data recovery. This scope and cost estimate does not include Burke Museum
curation fees.

RE: DUWAMISH GARDENS CONTAMINATED MEDIA STUDIES AND
OTHER COST OVERAGES SUMMARY
Dear Mr. Perfetti:
Shannon & Wilson (S&W) is submitting this letter to communicate recent cost overages related
to geotechnical borings and contaminated soils testing and laboratory analysis that are being
incurred on the Duwamish Gardens project. In addition, we understand additional work may be
performed on the project for cultural and archaeological studies, for which we recommend
including time for S&W environmental staff to provide observations during testing. We also feel
that extending the groundwater monitoring efforts would provide additional insight to project
design, and benefit the project. I have summarized our cost overages and recommended proposed
additional work below.

the data loggers next week (August 20, 2012). We recommend extending the groundwater
monitoring through winter and spring 2013. There are numerous reasons for extending the
groundwater monitoring:
• Winter flood and high tide maximum groundwater elevations can be documented for
geotechnical and slope stability design.
• The variability in daily fluctuations, related to bank stability, can be observed over
the fall/winter flood and spring runoff periods.
• Groundwater elevations measured in B-1 are directly linked to the Green River
surface water elevations. Measurement of this information can be used for finalizing
design elevations for winter and spring juvenile chinook migration periods. Currently,
surface water elevations are being approximated using the Lower Green River HEC-
RAS model.
The estimated cost to continue monitoring through May 2013 is $5,000, including monitoring
equipment rental extensions or purchases, three quarterly data downloads, report updates and
distribution of data, and administration of the work.

TASK 2.2 CULTURAL AND HISTORICAL RESOURCE INVESTIGATIONS
We have been diligently coordinating with J.A. Brennan and Paragon (ESA Adolfson) on
cultural and archaeological resource investigations. The expansion of the cultural resource
investigations has required additional time on behalf of S&W staff in support of the studies. We
have provided review of the proposed testing program; are recommending site visits during
testing; and have provided comment on potential geologic, sedimentation, and anthropomorphic
history that may provide insight to the site characterization. We would like to request additional
funding to continue supporting J.A. Brennan, Paragon, and the City of Tukwila on this matter.
Our proposed budget is as follows:
• Coordination and review time — 2 hours Principal-in-Charge/Vice President, 2 hours
Associate, and 2 hours Principal Engineer $1,000.
• On-site assistance — 16 hours Principal Engineer for on-site assistance and 2 days of
travel and 2 hours Associate for administration and contract management for $2,177.

Prepared For:
Ryan Larson, the City of Tukwila Public Works Department
Project Description
The project involves design and permitting services for the construction of estuarine fish habitat on a 2.16
acre City owed site. A conceptual site plan has been developed by the WDFW and calls for the
excavation of 55,000 cubic yards of material to establish approximately 2 acres of shallow water mudflat
and marsh habitat and approximately 0.8 acres of uplands planted with native vegetation.
Other work will include
• a small trail
• view deck
• kiosk
• Parking (on street or on site)
• Hand -carry boat launch
• Retaining walls (upland only)
• Minimal grading below OHW
The work to be performed by the CONSULTANT consists assisting with Section 106 tasks related to
archaeological site 45 -KI -703, Contract Plans, Specifications and Estimate (PS &E), and submitting all
required permits. Additional items may include the development of a contaminated soil remediation plan.
Task 1 —Administration
Administration tasks include meeting coordination, scheduling, contract administration and subconsultant
administration costs and expenses.
Task 2 — Site Inventory and Analysis
This task includes site investigations from a variety of disciplines in order to ascertain site conditions,
constraints and opportunities associated with the proposed design. Site inventory and analysis will
include survey, hydrologic analysis, geotechnical evaluation, contaminant testing, cultural resource
investigation, and other general site reconnaissance to collect important site information. The City of
Tukwila will provide wetland delineation if needed.
Task 21 Landscape Site Analysis
J.A. Brennan Associates:
J.A. Brennan will provide base mapping to team members, utilizing the survey and administer
existing information for review by the appropriate team members.
City of Tukwila Duwamish Gardens Scope of Work
Deliverable:
OHW delineation, base plan, vicinity map
Task 22 Cultural and Historical Resource Investigations
A recorded archaeological site (45 -KI -703) is located immediately east of the project area; the
site was excavated in 2005 prior to construction of Sound Transit's light rail line. The current
project is subject to Section 106 of the National Historic Preservation Act ( "Section 106 "). The
Section 106 process requires a project proponent to identify any cultural resources that may be
affected by a proposed project. Therefore cultural resources efforts will focus on determining if
cultural deposits extend into the project area. If cultural deposits do extend into the project area, it
is assumed those deposits would be eligible for listing in the National Register of Historic Places.
In order to evaluate the cultural deposits it will be necessary to determine the nature and extent of
the deposits, with a focus on any new information the newly identified deposits can provide
compared with the 2005 excavations. PRA's focus is on documenting the extent of any deposits
so that design plans can avoid impact to the greatest extent possible.
Task 221 Regulatory Assistance
Meetings
PRA will attend up to 3 meetings with tribes and USACE to assist with consultation
under Section 106 of the National Historic Preservation Act. The meetings are assumed
to be held on site or at City of Tukwila offices. The first meeting should be scheduled as
early in the planning process as possible in order to adequately address the concerns of
the stakeholders regarding archaeological site 45 -KI -703. It is anticipated that the first
meeting may inform the approach to conducting further cultural resources tasks.
Attendees at the first meeting are expected to include City of Tukwila project manager,
USACE archaeologists, tribal cultural resources staff, Department of Archaeology and
Historic Preservation (DAHP), possibly King County archaeologists, JA Brennan project
manager, and PRA staff.
Prior to the first meeting, PRA will review any notes or correspondence made by the City
during previous meetings with stakeholders regarding archaeological concerns.
Correspondence
PRA will prepare Section 106 correspondence for City of Tukwila signature.
Correspondence is expected to include consultation initiation letter and definition of Area
of Potential Effects. This task also includes reviewing correspondence sent by
stakeholders.
Task 222 Prepare Unanticipated Discovery Plan
Because of the proximity of a recorded archaeological site, it is anticipated that
stakeholders will request preparation of an unanticipated discovery plan (UDP). The UDP
will outline the procedures to be followed if additional cultural deposits are identified as
well as provide brief context for the site and any subsequent discovery. The UDP will not
be as detailed as a Monitoring Plan. A draft UDP will be prepared for review by
stakeholders. Upon receipt of comments, PRA will finalize the UDP. The City will be
responsible for distributing the draft and final UDP.
City of Tukwila Duwamish Gardens Scope of Work 2
The UDP should be approved before any ground disturbing activities take place on the
site.
The UDP should be approved before any ground disturbing activities take place on the
site.
Task 2.2.3 Observe Contaminated Soil Testing
Up to 14 geoprobes will be collected as part of the contaminated soils study. Because
observations made during contaminated soil testing will help to identify the nature and
extent of cultural resources, PRA will observe contaminated soil testing in coordination
with geotechnical investigations. This will be conducted to leverage deep testing
methods for cultural resources investigation. Cultural deposits (if present) are anticipated
at approximately 8 -10' below surface; geoprobe sampling will extend to 12' below
surface in order to exceed the expected depths of cultural deposits. This will allow a
deeper look than traditional archaeological sampling could accomplish. Fourteen
geoprobes will be taken from across the project area; sampling is anticipated to be
conducted for 2 days. PRA will visually inspect the geoprobes and take notes and
photographs. PRA will also take sediment samples for macrobotanical analysis.
Identification of cultural resources during soil testing will not be not be grounds for
stopping investigations (unless human remains are identified; human remains are not
expected).
Task 224 Macrobotan /cal Analysis
In order to evaluate whether cultural material extends into the project area, PRA will
analyze sediments for macrobotanical remains (presence of burned plants including
charcoal; this is not taxonomic analysis). This analysis is proposed based on the known
types of cultural deposits found at 45 -KI -703 (charcoal rich sand that is believed to be
more diffuse to the west of the 2005 site boundaries). Although charcoal staining is a
strong indicator of cultural materials, presence of macrobotanicals will provide a more
refined investigation and efficiently maximize cultural resources data collection identify
areas of cultural activity.
Task 2.2.5 Monitoring Memo
PRA will prepare a monitoring memo summarizing the results of the geoprobe
monitoring and microbotanical analysis; the memo will include maps incorporating
cultural resources data. PRA will submit the draft monitoring memo to City of Tukwila
for distribution to stakeholders. PRA will incorporate comments and produce a final
memo.
Task 2.2 Deliverables:
Meeting notes, draft correspondence, draft and final UDP, draft and final monitoring memo.
City of Tukwila Duwamish Gardens Scope of Work 3
Task 2.2 Assumptions:
1. No coordination will be necessary for the Carosino House or other standing structures
(such as documentation or consultation prior to demolition)
2. Only one draft of each deliverable will be required
3. The City will involve USACE in cultural resources discussions in anticipation of their
involvement; USACE involvement may initially be advisory.
4. Meetings are assumed to take up to 2 hours each plus travel time.
5. SEPA checklist will refer to the Section 106 work and will not require any additional
reporting for Question 13.
6. No construction monitoring is included. No data recovery or testing is included.
7. Additional mitigation efforts may be requested by stakeholders, depending on the results
of various investigations.
8. Archaeological investigations are expected to result in up to 1 cubic foot of samples
which will need to be curated. Every effort will be made to reduce the curation burden.
The cost for curation of samples is estimated at NTE $2000 (in perpetuity). This cost is
not included in the budget.
Task 23 Geotechnica/ Evaluation
Shannon & Wilson:
The geotechnical site assessment scope of services includes data collection, testing and
preliminary geotechnical design services for slope stability, foundation design of the viewing
platform, and construction dewatering.
Task 23.1 Subsurface Explorations
S &W will drill and sample 60 -foot and 40 -foot deep borings for purposes of slope
stability in the middle of the site. Soil samples will be taken at 2.5 -foot intervals in the
upper 20 feet and then at 5 -foot intervals below 20 feet. The two borings will have
pressure transducers /dataloggers for a period of two months to monitor groundwater
levels and fluctuations. If the soils in the two new borings are consistent with boring AB-
18 completed by AMEC for the Sound Transit pier at the southeast corner of the site,
S &W will assume that subsurface conditions are relatively uniform across the site and the
combined data will be used to design the pile foundations for a proposed public viewing
platform. If conditions are not consistent among the two new borings and the Sound
Transit pier boring, we will recommend an additional boring at the location of the
viewing platform.
Task 2.3.2 Laboratory testing
The laboratory testing program will consist of 12 grain size distributions and 18 water
contents to characterize the soils.
City of Tukwila Duwamish Gardens Scope of Work 4
Task 23.3 Slope Stability Analysis
Slope stability analyses will be performed at three locations for configurations of slope
and river fluctuations, to include the northern cut slope, the temporary dike between the
proposed basin and the river, and the cut slope in the proximity of the Sound Transit pier.
S &W will identify maximum stable side slopes of native material at each of the three
locations. This does not include interaction analysis between the proposed basin slope
cut and the Sound Transit pier.
Task 23.4 Viewing Deck Pile Design Analysis
S &W will provide recommendations for foundation support for a proposed viewing
platform and work with and provide design parameters for a structural engineer in the
deck design.
Task 235 Pavement Design Analysis
S &W will design will design a flexible pavement section for the parking area using the
1993 AASHTO Guide for Design of Pavement Structures.
Task 23.7Hydrogeologic Assessment
The groundwater hydrogeologic and environmental assessment objectives focus on two
key considerations including 1) characterization of groundwater hydrogeology for
evaluation of potential groundwater contamination and 2) construction dewatering
requirements.
Deliverables:
Technical Memo Geotechnical Site Evaluation
Assumptions:
Shoreline exemption permits to be provided by the City prior to drilling.
A proposed wall for a trail to the river's edge will not require design engineering.
The additional boring referenced above is not included in the cost estimate.
Anticipated traffic loads on parking area pavement will be provided by the City.
Subgrade modulus values for pavement design will be correlated from existing
geotechnical data; no new in situ or laboratory testing will be performed.
Contaminated Soils
Task24 Contaminated Soils & Groundwater
Shannon & Wilson:
The environmental scope of services includes a review of a previous Phase 2 Environmental Site
Assessment (ESA) prepared for the site in 2002 by Garry Struthers and Associates (GSA),
sampling to assess the presence and extent of the soil and groundwater contamination in order to
adequately characterize and design project specifications for disposal of soil excavated during
construction, and to address the potential treatment and discharge options for groundwater
generated during excavation dewatering. Based on review of the Phase 2 ESA prepared CDM in
2008 the following potential environmental issues will be assessed:
• potential near - surface soil contamination (based in information from the GSA report) and
City of Tukwila Duwamish Gardens Scope of Work 5
• contaminated groundwater at the northwest corner of the site.
Task 24.1 Previous Study Review
The Phase 2 ESA prepared by CDM was reviewed for preparation'of this scope. The
GSA report is referenced in that report, but was not previously available. The findings of
the GSA report, as reported, in brief, in the CDM report indicate that the surface soil at
the site is contaminated with carcinogenic polynuclear aromatic hydrocarbons (cPAHs),
lead, and chromium at levels that exceed the exceed the Washington State Department of
Ecology Model Toxics Control Act (MTCA) Method A cleanup levels. According to the
CDM report, this finding was based on extrapolation from composite samples collected
from four quadrants of the site. These results are important because they indicate that the
entirety of the surface soil at the site is contaminated at levels that would require special
handling and disposal, and in the case of the lead and chromium, additional waste
disposal characterization analysis.
We will review the GSA report to better understand the significance of these findings.
This may lead to a reduction in scope of the near - surface soil assessment in Task 2.4.2, if
GSA's interpretation of the data is found to be overly conservative or in error.
Task 24.2 Near - Surface Soil Assessment
A discussed above, the GSA Phase 2 ESA, as reported in the CDM report, indicates that
near - surface soils throughout the site are contaminated at levels that exceed the MTCA
cleanup levels. Soil contamination of this level will require special disposal at a Resource
Conservation and Recovery Act (RCRA) Subtitle D facility during construction.
However, the initial results were reportedly extrapolated from composite samples and are
likely conservative.
The following is an approximate summary of likely construction costs for clean and
contaminated soils:
• Clean soil disposal, $15/Ton, approximate $152,000 project disposal cost (not
including transport)
• Contaminated soil disposal at Subtitle D Facility, $45 /ton, approximate $450,000
project disposal cost (not including transport)
Performing the soils study could result in a project savings of $200,000 to $300,000, as
well as provide more comprehensive site characterization which could be beneficial
during project permitting and construction contract document development and the
bidding process. Therefore, this scope of services recommends the following soils
contamination work to complete the studies to confirm or discount the presence of these
contaminants at levels that will require special disposal during construction.
The site is approximately 2.16 acres in size, and samples will be collected for the top 2
feet using Ecology's guidance on sampling The approximately —7,000 cubic yards of
soils in question would be sampled at a rate of 10 samples per the first 2,000 cubic yards
of material, and then an additional sample for each additional 500 cubic yards thereafter
for a total of 14 geoprobe samples, with soils samples also collected from 2 geotechnical
borings, will be required to characterize the upper 2 feet of soil. The site will be divided
into 20 approximately equal sized grids and the geoprobes will be advanced at the
approximate center of each grid.
City of Tukwila Duwamish Gardens Scope of Work 6
The samples will be collected using a direct -push geoprobe rig. The geoprobe is a direct
push boring rig with a 2 inch outside - diameter (O.D.) casing that is advanced using a
percussive force rather than using an auger to remove soils in its path. Geoprobe soil
samples are collected in 4 -ft long, plastic lined sections. While only the near - surface soil
is assumed to be contaminated, the geoprobes will be advanced and 3 samples collected
for each boring to 12 feet below ground surface to provide additional information for the
cultural resources assessment. Soil samples collected from the geoprobes will be
classified according to their geology and field screened for volatile organic compounds
(VOCs) and hydrocarbon contamination using a photoionization detector (PID). Prior to
conducting the field work, we will prepare an internal Sampling and Analysis Plan that
describes in detail the proposed sampling procedures.
One composite laboratory contaminated soil sample each will be collected from the 0 -2
foot interval and the 2 -4 foot geoprobe tubes. Both samples will be submitted to the
laboratory for analytical testing for cPAHs, lead, and chromium; however, only the 0 -2
foot interval sample will be analyzed initially. If the results of the 0 -2 foot sample
indicate that the soil in that interval is contaminated above a MTCA Method A cleanup
level, then the 2 -4 foot interval sample will be analyzed to assess the potential vertical
extent of contamination. Additional samples may be collected if field screening of the
geoprobe cores indicate that a contaminant other than PAHs and metals is present, and/or
if indications of contamination are
Each geoprobe location will be cleared by both private and public utility locators. We
anticipate that the sampling will take 2 full days to complete.
We will prepare a media characterization report that includes a summary of our field
work, figures showing sample locations and soil disposal designation for each grid, tables
summarizing the analytical data, and the raw analytical laboratory reports.
Task 24.3 Contaminated Groundwater
The groundwater hydrogeologic and environmental assessment objectives focus on two
key considerations including characterization of groundwater hydrogeology for
evaluation of potential groundwater contamination and construction dewatering
requirements (see previous task 2.3.5 above).
A previous Phase 2 ESA study indicated that solvent - related volatile organic compounds
(VOCs) were detected in groundwater samples. The groundwater assessment will further
evaluate the presence of these contaminants in groundwater that could affect discharge
permitting for dewatering fluids generated from that area of the site.
Up to five groundwater samples will be collected in the geotechnical borings and wells
and geoprobe sampling locations. The samples will be submitted to an analytical
laboratory for analysis of halogenated VOCs. The results of this analysis will be
included in the media characterization report along with our recommendations for
potential treatment of contaminated dewatering fluids prior to discharge.
Deliverables:
Technical Memo — Soils and Groundwater Contamination Report
Assumptions:
City of Tukwila Duwamish Gardens Scope of Work 7
1. According the Phase 2 ESA, there are also two underground storage tanks
present at the site, however; it is our understanding that these tanks will be

Task 26.2 Project existing and proposed hydraulics
A project hydraulic assessment is necessary to evaluate the project effects on floodplain
water surface elevations, which are part of permit reporting requirements, erosion
protection, bank stabilization, and slope stability design evaluation. The project existing
hydraulics will include the following tasks:
• Document existing hydraulic conditions (water surface elevations,
velocities, shear stress, ramping and drawdown conditions) as obtained
from the HEC -RAS model for the following key periods:
o FEMA 1% exceedance flood (confirm with King County FEMA
Flood Insurance Study and updates)
o Construction season conditions
• Provide a review of the hydrologic record for tidal and river inundation,
flow duration and ramping characteristics to be incorporated into the

A complete survey of the site was performed by Sound Transit in 2005, in which Lin &
Associates performed the majority of the work and includes property and easement boundaries.
This survey will be used for conceptual design. Pick -up surveys will be needed to update the
basemap and /or expand the area shown to allow for final design. The survey datum will be
MLLW. Geotechnical borings and test pits will be surveyed and added to the basemap.
Deliverables:
• A copy of the survey on electronic media with property and easement lines. The drawing
shall be compatible with AutoCAD and shall be one drawing file.
• An ASCII file of reduced survey points including the point number, northing, easting,
and elevation based on the required horizontal and vertical control to be used.
• An electronic AutoCAD file with the triangulated irregular network (TIN) of the digital
terrain model for the topographic survey and will include a copy of the Land
Development Desktop directory with files which make up the surface.
Task 3— Alternatives Design
Two alternative plans will be prepared for review by staff, stakeholders and the public. The alternative
designs will be based on the WDFW Concept Design, 2B, which has been selected as the preferred
alternative from that process. Alternative designs will utilize new site analysis investigations and
information to finesse the preferred alternative to meet habitat goals, add recreational and interpretive
elements, and accommodate maintenance and security needs.
The alternatives and memorandum that were completed as part of the WDFW Concept Study will be
reviewed in order to understand previous investigations and incorporate project goals and relevant design
ideas into the alternatives design.
