PROPOSAL
To:Mike Perfetti, City of Tukwila
From:Stephenie Kramer
Date:August 31, 2022
Re:Chinook Winds Desktop Review
Willamette Cultural Resources Associates, Ltd (WillametteCRA) is pleased to submit a proposal to assist
the City of Tukwila (City) in meeting requirements by the Washington State Recreation and Conservation
Office (RCO) in preparation for the Chinook WindsPublic Access Project(Project). The Project will
includedevelopingtrails, educational kiosks, aparkinglot,and connecting a stormwater system to
existing infrastructure along Tukwila International Blvd.
Portions of the Project area are currently being developed by King County Water and Land Resources
Division (WLRD) and WillametteCRA has been monitoring excavations pursuant to a Monitoring Plan
developed for the project after field investigationsin 2018.Project area stratigraphyis complex with intact
native sediment deeply buried under fill. However, excavation of fill during recent Project activities may
have resulted in intact native sediments closer to the current ground surface.
The City has requested cultural resources support from WillametteCRA for the Project. Our proposed
scope of work would consist of the following assumptions and tasks as listed.
The extents of both the prior cultural resources surveysand prior disturbance relative to the proposed
Project will be examined and comparedwith City plans. If datasuggest intensive survey is needed or if
conditions warrant monitoring, WillametteCRA will make recommendations.
Approach
As noted above, WillametteCRA will begin this investigation with a review of existing data and literature,
including:
Records of previously identifiedcultural resources and prior surveys in the Project area
Data on file at WillametteCRA derived from recent monitoring at the Chinook Winds Project area
Current elevations
Proposed Project plans and depths of proposed excavations relative to existing elevations and
recent ground-disturbing activity.
Scope of Work
Our proposed scope of work would consist of the following:
655 S. Orcas St., Suite 220,Seattle, Washington 98108

WillametteCRA will review available records of prior construction,geotechnical exploration,and current
elevationsto ascertain whether the Project has the potential to intersect with intact native sediments and
toevaluate the potential for archaeological resources.WillametteCRA will complete a technical memo for
review by the City and RCO. This memowill describe the Project areaand planned excavations depths,
current Project area elevations and locations where proposed Project excavations may intersect with
intact native sediments with potential to contain archaeological resources, and provide any
recommendations regarding management of cultural resourcesthat may beappropriate. One internal
draft will be prepared and submitted to the Cityfor review to ensure accuracy of project information as
conveyed in the report.We assume all deliverable submittals will be electronic, as MS Word and/or PDF
documents, and we assume the City will submit the memo to RCO for review.The WillametteCRA
Principal Investigator will provide project oversight and lead production of project deliverables. The
Project Manager will provide quality assurance, serve as primary contact to the City, and will provide
timely communications regarding project timelineanddelivery,andwillprovide invoicing.
Assumptions:
i.Current elevation datawill be provided
ii.Project shapefiles and detailed project plans will be provided
iii.No fieldwork is necessary for the review although future phases may require fieldwork or monitoring
Cost Proposal
Fees willbe billed on an hourly not-to-exceed basis. A detailed budget is attached. Thisproposal also
assumes that ground disturbance willbe limited to the areas depicted in the project plansprovided.
Schedule
WillametteCRA will begin taskswithin one weekof Notice to Proceedand receipt of plans and elevations;
with adraft memo completed within approximately threeweeks. Accordingly, we anticipate the basic
services to require up to fourweeks to complete.
Please let me know if you have any questions regarding this proposal.If our proposal is acceptable, we
will begin upon your notice to proceed.
