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 1 81 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. 2. See Attachment A for further assumptions.

The scope (Attachment A) and cost estimate (Attachment B) 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). Initiation 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 htt�J/www.burkemuseum.ora/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 Principal Investigator Northwest Cultural Resources 83 rESA Paragon 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 USAGE has requested site delineation for 45 -KI -703, a precontact 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 design team, DAHP, King County Historic Preservation Program, and the interested tribes. ESA Paragon will also maintain project schedule and budget. Task 2. Archaeological 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 wi11 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 84 rESA Paragon Attachment A Scope of Work Duwamish Gardens Site Delineation 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 appropriate 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 anticipated 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 -KI -703, as required by DAHP. One new archaeological site forms will be completed if historic -period components that are not temporally associated with precontact occupation at 45 -KI -703 are encountered during fieldwork. Task 7. Curation Preparation. ESA Paragon will prepare records, photographs, and data for curation, meeting the Burke Museum's curation requirements; ESA Paragon assumes that project records, photographs, and data 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/samples for curation, meeting the Burke Museum's curation requirements; ESA Paragon assumes that the collection will consist of not more 300 unique catalog numbers, and occupy not more than 4 cubic feet. This cost estimate does not include Burke Museum curation fees. 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 archaeological 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 -KI -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, smooths -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 alI 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. 85 r ESA Parl Attachment A Scope of Work Duwamish Gardens Site Delineation • Under Task 3, up to 10 archaeological test units will be excavated. Each test unit may take up to two (2) days to excavate by two (2) archaeologists (4 person days 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 data will not exceed 20 linear inches, and artifacts/samples will not exceed 300 unique catalog numbers occupying not more than 4 cubic feet. • One set of consolidated comments on the draft Technical Report will be provided to ESA Paragon by the Client. Cost Proposal: ESA Paragon has estimated the cost for the Duwamish Gardens Site Delineation based on the hours and rate schedule included in Attachment B. ESA Paragon estimates that the sum of $71,546 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 ofa Supplemental Treatment Plan, or conducting data recovery. This scope and cost estimate does not include Burke Museum. curation fees. 86 EskParagor -4111 Budget Proposal Version: 2 Project No.: Project Title: Duwam is h Gardens Site Delineation Client: J.A.

EXPECTED DATA CATEGORIES Prehistoric archaeological remains recovered during testing and data recovery at 45-K1-703 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 July 2012 90 ANA IJYTICAL THC HN IQU>IS A nalyses ofIarlifhc'ts and sample's aolleicleic curing arahaealogic'al 1esilinigl art Duwamish Gander's will lie conc u al eic flan the purpose oil assessing l h e potential to ac dress rciseanah c amains relevant t o 45-K1.103 a9 seat forth by Hlukis Onat cit al.

August 15, 2012 Mr. Mike Perfetti J.A. Brennan Associates PLLC 100 S. King Street, Suite 200 Seattle, WA 98104 RE: DUWAMISH GARDENS CONTAMINATED MEDIA STUDIES AND OTHER COST OVERAGES SUMMARY Dear Mr. Perfetti: ALASKA CALIFORNLA COLORADO FLORIDA MISSOURI OREGON WASHINGTON 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. TASK 2.3.A GEOTECHNICAL INVESTIGATIONS (ADDITIONAL GROUNDWATER MONITORING) The groundwater monitoring period specified in the scope includes a 2 -month monitoring period, which occurred during mid-June through mid-August 2012. Our current plan is to decommission 400 NORTH 34th STREET - SUITE 100 PO BOX 300303 SEATTLE, WA 98103 206-632-8020 FAX 206-695-6777 TDD. 1-800-833-6388 www shannonwilson.com 98 21-1-12368-024 Mr. Mike Perfetti J.A. Brennan Associates PLLC August 14, 2012 Page 2 of 4 SHANNON &WILSON, INC. 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. 21-1-12368-021-L 1.docrlwpllkia 21-1-12368-024 99 Mr. Mike Perfetti J.A.

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. 21-1-12368-024-L1.doexdwp/lkn 100 21-1-12368-024 Mr. Mike Perfetti J.A.

Task 2.2 -- Cultural and Historical Resources Investigations $3,177 Task 2.3 Ccotcchnical Investigations (cost overages) 131 Task 2.3.A — Geotechnical Investigations (extend GW monitoring) 5,000 3,955 2,z 400 Total Request 515,463 We understand that the project is limited to funding by the City and grant limits and timelines. However, we do feel that changes in the project schedule, cultural resources conditions, additional costs to complete soils testing, and the opportunity for extending groundwater monitoring are justifiable requests to the City.
