DATE: January 24, 2025
SUBJECT: Surface Water Fund — Duwamish Hill Preserve Phase 3 & S. 104th St Shoreline
Restoration Project
Project Numbers 92241203 and 92541203
Design Contract with Anchor QEA
ISSUE
Approve a professional services contract with Anchor QEA for design services for both the Duwamish Hill Preserve Phase 3
and S. 104th St Shoreline Restoration Project CIPs.
BACKGROUND
The Duwamish Hill Preserve Phase 3 project builds on a long-standing park masterplan and WRIA 9 Habitat Plan project to
create off -channel habitat and expand the park visitor experience. The park master plan calls for moving a portion of S. 115th
St landward to improve shallow water habitat, water quality and enjoyment of the shoreline. This scope of services includes
site investigation, community outreach, conceptual design alternatives and an implementation roadmap.
S. 104th St Shoreline Restoration Project is also a WRIA 9 Habitat Plan and long-standing CIP project aimed at improving the
oversteepened and armored shoreline, developing solutions to create a sustainable shoreline that can erosional risk to
uplands and provide ecological value. The project will explore the idea of modifying, abandoning and/or vacationing S. 104th
Street. Note that staff are discussing partnership opportunities with King County's Mitigation Reserves Program, who are
actively seeking mitigation sites. As such, there is potential for scope reduction or modification beyond task 1.1.
DISCUSSION
Staff solicited proposals, held interviews and selected Anchor QEA to provide design services for both the Duwamish Hill
Preserve Phase 3 and S 104th St Shoreline Restoration Project since the sites are in proximity to one another and present
many of the same considerations including a restoration goals, adjacency of local roads within the project area, steep slopes,
hydrologic issues, and both are at the project initiation phase.
FISCAL IMPACT
Contract Amount Duwamish Hill CIP Budget S 104th Shoreline CIP Budget
DHP3 (Task 2) $229,795.00 $ 230,000.00
S 104th St Contract (Tasks 1, 3) $223,407.00 $272,000.00
Total $453,201.00
The contract amounts are within the CIP project budgets, sourced from the Surface Water Enterprise (412) Fund. Staff intend
on submitting a grant application this year to fund design services for Duwamish Hill Preserve Phase 3 and will continue to
seek funding and/or partnerships for both projects over time.
RECOMMENDATION
The Council is being asked to approve a contract for $453,201.00 with Anchor QEA and forward to consent agenda at the
February 3, 2025 regular council meeting.

South 104th Street Shoreline Restoration and Duwamish Hill
Preserve Phase 3
City of Tukwila
1. Project Understanding
The City of Tukwila (City) seeks to identify opportunities to improve salmonid and wildlife habitat
corridors along the Duwamish River while also considering urban infrastructure and use including
roadways, utilities, property acquisition, and public use. The City has identified two project sites
along the Duwamish River: South 104th Street and Duwamish Hill Preserve.
South 104th Street
The South 104th Street project site includes 1,000 linear feet with significantly degraded and
constrained habitat. The shoreline is characterized by an oversteepened riprap slope with invasive
Himalayan blackberry.

The 2021 Water Resource Inventory Area (WRIA) 9 report identifies five key habitats that could be
restored along the 1,000 linear feet of shoreline: backwater, Duwamish marsh, Duwamish mudflat,

edge, and riparian. The brackish condition of the site provides an opportunity for diverse vegetation
communities along the tidally influenced shoreline. The South 104th Street site includes the South
104th street roadway, four stormwater outfalls, and multiple utilities including overhead lines.
The South 104th Street project site falls within privately owned property and City right of way and
includes a revetment on King County's inventory. Boeing owns the parcels north of the project
footprint, where a public pedestrian pathway follows the shoreline and then crosses the Boeing -
owned South 102nd Street bridge to a public shoreline access trail that connects to the Port of
Seattle's Salmon Cove Park and the regional Green River Trail.
Three parcels in the project area are privately owned. The northernmost parcel extends waterward of
the South 104th Street right of way and offers considerable area for habitat creation and restoration.
The property is vacant and posted for lease. City staff have been in touch with the leasing agent and
King County's In -lieu Fee Mitigation Program manager who, at the time of this writing, has or will be
reaching out to the listed property owner of this and the adjacent property to express an interest in
purchasing the property and restoring habitat to include in its mitigation bank portfolio. The
outcome of this potential purchase scenario will affect the SOW.
Duwamish Hill Preserve
Located on an ancient glacial deposit perched above the Duwamish River, the Duwamish Hill
Preserve has been a significant place to Puget Sound Salish Tribes for generations. The hill provides
views up and down the Duwamish River and, of particular cultural importance, of the North Wind
Weir located just upstream.
Forterra acquired the 10.5-acre property in 2004, transferring the property to the City, who led the
2007 master planning effort to create the Duwamish Hill Preserve as described on Forterra's current
website (Figure 2). Soon afterward, Phases 1 and 2 were completed with significant support by
community volunteers. The open space preserve has a trail system, Cultural Garden, and outdoor
classroom alongside interpretive opportunities and restored habitats.
The 2007 master plan identified Phase 3, which is focused on restoring the Duwamish River shoreline.
The existing shoreline is a narrow corridor with limited riparian habitat. South 115th Street is set back
approximately 50 feet from the river's edge, providing some space for restoration. Realigning the street,
as shown in the 2007 master plan, which will be considered, would expand restoration potential for
side channel, marsh, and mudflat habitat. Modifications to the roadway would involve existing
utilities including electrical poles and conduit, stormwater closed pipes, catch basins, and culverts.
The project area includes the Phase 3 area as well as the right riverbank upstream of the Duwamish
Hill Preserve that runs along South 115th Street, where a landslide event occurred in January 2022
and the western extent of South 115th street to the East Marginal Way intersection.

In addition, the City recently acquired two easterly parcels, which offer new space for restoration near
the shoreline, with potential for invasive vegetation removal and new native riparian communities. In
response to complaints about dumping and other nefarious use of the road shoulder, the City (led by
the Department of Parks and Recreation) is installing a temporary berm that will limit the amount of
available parking and prohibit unobstructed vehicular access to the immediate shoreline.

Proposed Work Approach
To approach the feasibility of the unique restoration opportunities at both project sites, Anchor QEA
has developed the following Scope of Work (SOW). The SOW tasks are organized by project site:
Task 1 for South 104th Street and Task 2 for Duwamish Hill Preserve. Under each task, we include the
following subtasks:
• Project Management
• Site Investigation
• Engagement and Outreach
• Basis of Design
• Conceptual Design Alternatives
• Implementation Roadmap
Ultimately, the SOW will provide the City with two feasibility studies that identify alternative
strategies for each project site and inform the next phases of work.
19
January 17, 2025

The SOW also includes an optional Task 3 to conduct a Phase 1 Environmental Site Assessment (ESA)
for the South 104th Street parcels, if the City is acquiring the property or properties.
Within the SOW, we have included three subconsultants to support the effort: KPG Psomas for
upland survey, Woolpert for bathymetry survey, and Heffron Engineering (Heffron) for transportation
planning and analysis. The KPG Psomas and Woolpert proposals are included as Attachment 1.
2. Scope of Services and Deliverables

Spooner). Up to one additional Anchor QEA team member will also attend. Biweekly meetings will
focus on the Task 1 South 104th Street project and the Task 2 Duwamish Hill Preserve project. For
the purposes of scoping, our fee assumes that project management will extend over a 12-month
period. Half of the biweekly meetings are included in Subtask 1.2 and half of the biweekly meetings
are in included in Subtask 2.1.
This task also includes City meetings at key project milestones. Meetings will occur at the following
steps in the project:
• Project kickoff meeting (2 hours, in person at City offices, with three core consultant team
staff)

Subtask 1.3: Site Investigation
Tasks 1.3 through 1.7, will be informed by the outcomes of Tasks 1.1 and will require prior
written authorization by City prior to any work on these tasks.
Survey
Anchor QEA's subconsultant, KPG Psomas, will complete a topographic survey for upland project
areas as shown in Figure 1 (see Attachment 1 for subconsultant proposal). The survey will include
ground features, such as extent of pavement, curbs, fences, trees, ditch features, and aboveground
utilities. The survey will include a utility locate to mark and survey underground utility locations. The
survey will include establishing the lot lines using publicly available GIS data and surveying the right
of way and lot lines.
Anchor QEA's subconsultant, Woolpert, will complete a bathymetric survey along the project area's
shoreline (see Attachment 1 for subconsultant proposal).
Anchor QEA will develop a single basemap incorporating the upland and bathymetric survey files.
Background Information Review
This task will involve a review of existing documents provided by the City and available publicly. This
will include the review of existing documents and information or data evaluation for multiple
technical disciplines:
• Geotechnical (from recent projects such as Chinook Wind and Duwamish Gardens)
• Hydrologic and hydraulic (available modeling documentation from Lower Duwamish
Waterway projects)

Transportation Assessment
Heffron will evaluate the opportunities to fully or partially vacate or abandon South 104th Street as
part of the project, and whether those options would require roadway mitigation measures. The
assessment would include the following tasks:
• Assess daily traffic patterns on South 104th Street. Commission 7-day traffic counts (by a
contracted vendor) on South 104th Street, and compile counts to assess current use by time
of day and day of week.
• Assess peak hour traffic operations at near -site intersections. Commission peak period
(AM and PM) traffic counts at up to three intersections that could be affected by the South
104th Street closure: East Marginal Way/South 102nd Street, East Marginal Way/South 104th
Street, and South 104th Street/South 102nd Street. Evaluate current intersection operations.
• Evaluate traffic effect of design options. Evaluate how full or partial closure of the street
would affect local access to properties (that may remain with the project) and at nearby
intersections. Trips that currently use South 104th Street would be reassigned to likely
diversion routes, and the effect on intersection and site access operations will be assessed. All
traffic operations analyses will be performed using Synchro 11 (or newer) software. A No
Action condition and up to three project options will be evaluated.
• Evaluate non -motorized transportation. Evaluate how pedestrian and bicycle traffic that
may now use South 104th Street would be accommodated with up to three project
alternatives.
• Determine mitigation. Develop potential improvements that could be made for each
alternative to mitigate any adverse impacts.
• Document results in a technical memorandum. Draft findings will be reviewed with the
project team to inform the project design criteria. The budget assumes up to two rounds of
review before a final version of the technical memorandum is completed.

Subtask 1.6: Conceptual Design Alternatives
Design Alternatives
Anchor QEA will develop three conceptual design alternatives that consider the existing conditions,
project goals, opportunities, and constraints as documented in Subtask 1.5. The design alternatives
will propose different approaches (ranging from a restoration minimum to a maximum) to restoring
the shoreline, vacating/abandoning South 104th Street, modifying utilities, and incorporating
adjacent upland properties. Each design will include a plan and up to two sections. The conceptual
alternative plan and section drawings will be simple, basic scaled drawings over a basemap. The plan
24
January 17, 2025
South 104th Street Shoreline Restoration and Duwamish Hill Preserve Phase 3
Page 9
and section drawings will be color rendered in a basic, consistent way to provide clarity of
communication. A conceptual rough order -of -magnitude (ROM) opinion of probable construction
cost (OPCC) will be developed for each of the alternatives to assist in comparing the alternatives.
Mitigation Credit Alternative Analysis
Anchor QEA will develop estimates of expanded aquatic restoration area and potential mitigation
credits generated for each alternative. Mitigation credits will be presented for each alternative in a
summary table.
Alternative Analysis and Preferred Alternative
Anchor QEA will analyze the alternatives based on the evaluation criteria generated in subtask 1.5.
Anchor QEA will develop a summary of the alternative evaluation and analysis in the form of a
summary matrix showing the evaluation criteria and rankings with the intention of choosing one of
the conceptual design alternatives as the preferred alternative. If one conceptual design alternative is
not determined to be the preferred alternative, the desired elements that scored well in the
alternative analysis will be summarized to inform the future development of the project.
For the preferred alternative, Anchor QEA will develop one axonometric visual rendering of the
preferred conditions.

the development of the project's basis of design (Subtask 2.4) and the second meeting will occur
following the development of the conceptual design alternatives (Subtask 2.5). The meetings will
occur at a centrally located public building organized by the City.
Anchor QEA will facilitate these meetings with the City project manager providing a supporting role.
Anchor QEA will prepare presentation and meeting materials including PowerPoint presentations,
presentation boards (up to three boards per meeting), and additional facilitation materials such as
notetaking boards and white boards for public comments. The presentation materials will utilize
graphics developed in other project subtasks. Presentation materials will be suitable for future City
use in presentations to City boards, commissions, and elected leadership.
Meeting participants will be encouraged to write comments during the meeting. Anchor QEA
meeting facilitators will also document comments during the meeting with live notetaking.
Anchor QEA will transcribe all comments after the meeting. No additional meeting notes will be
provided.
Simultaneous to the community meeting, the City will launch an online survey using a platform such
as Survey Monkey. Anchor QEA and the City will collaborate on the survey content. Anchor QEA will
manage a live survey during the meeting and then leave the survey open for a defined period after
the meeting to allow for more community feedback. Once the survey is closed, Anchor QEA will
download and review the online input and develop summary visual content representing the survey
results to present to the City to assist with project decision making. Meeting materials and survey
results will be posted by the City on their website.

30
January 17, 2025
South 104th Street Shoreline Restoration and Duwamish Hill Preserve Phase 3
Page 15
alternatives will propose different approaches (ranging from a minimum to a maximum restoration)
to restoring the shoreline, moving South 115th Street, modifying utilities, and providing new public
access elements both within Duwamish Hill Preserve and for connection to Duwamish Gardens. Each
design will include a plan and up to two sections. The conceptual alternative plan and section
drawings will be simple, basic scaled drawings over a basemap. The plan and section drawings will be
color rendered in a basic, consistent way to provide clarity of communication. A conceptual ROM
OPCC will be developed for each of the alternatives to assist in comparing the alternatives.
Mitigation Credit Alternative Analysis
Anchor QEA will develop estimates of expanded aquatic restoration area and potential mitigation
credits generated for each alternative. Mitigation credits will be presented for each alternative in a
summary table.
Alternative Analysis and Preferred Alternative
Anchor QEA will analyze the alternatives based on the evaluation criteria. Anchor QEA will develop a
summary of the alternatives evaluation and analysis in the form of a summary matrix showing the
evaluation criteria and rankings with the intention of choosing one of the conceptual design
alternatives as the preferred alternative. If one conceptual design alternative is not determined to be
the preferred alternative, the desired elements that scored well in the alternative analysis will be
summarized to inform the future development of the project.
For the preferred alternative, Anchor QEA will develop one axonometric visual rendering of the
preferred conditions.

Task 3: South 104th Street Phase 1 Environmental Site Assessment —
Optional Task
Task 3 may be informed by the outcomes of Task 1.1 and will require prior written
authorization by City prior to any work on this optional task.
Anchor QEA will support the City in preparation for development of the South 104th Street property
located in Tukwila, Washington, by conducting a Phase I ESA. The ESA will be performed at the
Subject Property consisting of three tax parcels located at 10215, 10315, and 10325 East Marginal
Way South in Tukwila, Washington (Tax Parcel IDs: 0423049002, 0423049051, 0423049117,
respectively).
Under Task 3, Anchor QEA will complete the Phase I ESA in accordance with 40 Code of Federal
Regulations Part 312 — Innocent Landowners, Standards for Conducting All Appropriate Inquiries using
the methods described in ASTM standard E1527-21. This work will document the history of the
Property and surrounding area, survey available information regarding environmental conditions,
document current conditions at the Property, and identify any recognized environmental concerns
(RECs) that indicate a potential release of hazardous substances to soil or groundwater.
The Phase I ESA will include the following specific elements:
• Site reconnaissance, including a visual on -site inspection of the Property during a 1-day site
visit
• Interviews of up to three persons knowledgeable about the Property, including (as available)
current and past owners, operators, occupants, or state or local governmental officials
• A review of historical property records and historical aerial photographs
• A review of federal and state environmental records concerning waste management practices,
underground storage tank records, and/or documentation of historical releases at the
Property
• Identification of other commonly known or reasonably ascertainable information about the
Property
Site Visit and Interviews
As part of the Phase I ESA, Anchor QEA will conduct an in -person site inspection of the Property. The
site inspection will be performed to visually assess and document current Property conditions and to
evaluate/identify potential areas of concern based on visual review.
32
January 17, 2025
South 104th Street Shoreline Restoration and Duwamish Hill Preserve Phase 3
Page 17
Following the site visit, up to three persons knowledgeable about the Property will be interviewed to
provide additional information about historical activities at the Property. Topics addressed during
each interview may include the following:
• Historical operations that have occurred throughout all areas of the Property
• Handling/use of chemicals or other materials that could have resulted in potential
environmental impacts to the Property including, for example, presence of waste oil drums
and underground storage tanks
• Records of any environmental incidents (spills, releases, etc.) that have occurred at the Property
• Records of Property improvements and/or modifications (new buildings, excavation areas,
paving, etc.)
Deliverables
• Anchor QEA will prepare and submit a draft and final Phase I ESA Report that covers all tax
parcels, identifying the findings, opinions, and conclusions of the assessment.
The report will document the methods used to perform the Phase I ESA, provide full
documentation of the work completed and records reviewed, an evaluation of the RECs
(if applicable), describe results of the Phase I ESA, and provide Anchor QEA's
professional recommendations.
- If applicable, the report will include an identification of site -specific data gaps and a
description of appropriate field investigation methods that can be used to resolve these
data gaps.
3. Assumptions
• Regular check -in meetings with the City will occur virtually. City milestone meetings will occur
at the City's offices.
• Meetings in addition to those described in this SOW are not included and will be considered
additional work.
• Outreach and engagement meetings will rely on materials in other tasks to produce outreach
materials.
• Anchor QEA will facilitate outreach and engagement meetings. The City will determine who is
invited to meetings, provide all meeting invitations, and coordinate meeting logistics,
including securing meeting rooms and ensuring that audio-visual equipment is available and
in working order.
• Community meetings will occur in the evening and will be a conventional format with a
presentation followed by a question -and -answer session.
• The City will provide project updates on a City -led online platform (such as the City's website).
This will include posting community meeting presentations and community survey results.
• The City will lead outreach with all Tribes.
33
January 17, 2025
South 104th Street Shoreline Restoration and Duwamish Hill Preserve Phase 3
Page 18
• Travel time will be billed to the City. Travel time from Seattle to the City is estimated at 1 hour
round trip.
• Alternatives will be developed within the project areas identified in Figures 1 and 2. If the
project boundaries expand, Anchor QEA will discuss with the City which level of evaluation
and/or design work can be conducted within those additional areas within the scope and fee
negotiated for this work.
• No permitting applications or formal agency correspondence will be prepared under this
SOW.
• Tasks 1.2 and 2.2 background information reviews will rely on existing information; no new
site (e.g., soil geotechnical or natural resource field data) data collection is included in this
SOW. If significant data gaps are identified during the technical review, they will be
summarized and included in the discussion data gaps in the final report. Technical reviews will
inform the conceptual alternatives and alternative analysis on a conceptual level only.
• Site investigation work is limited to the work described in Tasks 1.2 and 2.2. If additional site
investigations work is deemed necessary, it will be negotiated as additional work under a
contract amendment.
• The survey does not include a boundary survey with calculated lot lines and easements (and
does not include the additional research and calculations for the boundary survey). The survey
does not include recording the survey as Records of Survey.
• The City does not currently have a maximum allowable construction cost for the South 104th
Street restoration or Duwamish Hill Preserve Phase 3 Projects. The preferred alternative
conceptual design will inform the City's maximum allowable construction cost.
• An OPCC will be developed as ROM costs to reflect the level of design (conceptual) and will
include a contingency markup appropriate to this stage of design.
• A new OPCC will not be developed for the preferred alternative for either South 104th Street
or Duwamish Hill Preserve. It is assumed that the preferred alternative will be one of the three
developed alternatives and there will not be changes to the OPCC.
• The SOW does not include time for developing grant applications.
4. Budget
Exhibit B provides a detailed summary of the proposed fee.
5. Schedule
Work will begin immediately after a contract is executed (expected in January 2025). South 104th
Street and Duwamish Hill Preserve schedules are not expected to run parallel and will be on their
own tracks. It is expected that final reporting for both South 104th Street and Duwamish Hill Preserve
will be completed by the end of 2025.

CITY OF TUKWILA CAPITAL PROJECT SUMMARY
2025 to 2030
PROJECT: Duwamish Hill Preserve Phase 3
Project # 92241203
Project Manager Mike Perfetti Department Surface Water
DESCRIPTION:
The goals of the project are to restore the shoreline to create off -channel habitat and expand the park visitor
experience. The park master plan calls for moving a portion of S. 115th Street landward to improve shallow water
habitat, water quality and enjoyment of the shoreline. Final design will be informed by a feasibility evaluation and
alternatives evaluation process.
JUSTIFICATION:
This project is described in the Duwamish Hill Preserve Park Master Plan and is listed as Project DUW-63 in the WRIA
9 Salmon Habitat Plan (2021)
STATUS:
The project has some funding in the 2023-24 CIP for initial feasibility work. Project initiation and consultant
advertisement is planned for 2024.
This is a work in progress. The Green Infrastructure Program Proposal is intended, in part, to address maintenance
MAINTENANCE IMPACT:
needs for PW-initiated habitat restoration projects and helping to alleviate pressure on Parks' given resource
constraints. Note that vegetation management maintenance needs decrease over time as planted vegetation
The City completed acquisitions of properties identified in master plan that may be used for this project. Two small
COMMENT:
additional undeveloped properties are for sale that would expand the park footprint.

CITY OF TUKWILA CAPITAL PROJECT SUMMARY
2025 to 2030
PROJECT: S. 104th St Shoreline Restoration
Project # 92541203
Project Manager Mike Perfetti Department Surface Water
DESCRIPTION:
The armored bank on an outside bend of the Duwamish River adjacent to S. 104th Street is steep and subject to
erosion and potential failure. This project would analyze site conditions and develop solutions to create a sustainable
shoreline that can withstand hydraulic forces, reduce erosional risk to uplands and provide ecological value.
JUSTIFICATION:
This is project DUW-26 in the WRIA 9 2021 Salmon Recovery Plan Update. The City roadway and adjacent properties
and utilities may be at risk under current conditions.
STATUS:
The project is running behind schedule; the intent is to start with a geotechnical analysis of the bank, analysis of
existing conditions and conceptual feasibility and alternative design.
This is a work in progress. The Green Infrastructure Program Proposal is intended, in part, to address maintenance
MAINTENANCE IMPACT:
needs for PW-initiated habitat restoration projects and helping to alleviate pressure on Parks' given resource
constraints. Note that vegetation management maintenance needs decrease over time as planted vegetation
This project initiatlly appeared in the 2003 Surface Water Comp Plan as "S 104th St Bank Stabilization Project", in
response to some observed erosion; despite this, the bank appears somewhat stable, but is extremely steep and
COMMENT:
cracking is observed on the roadway; some adjacent land uses and access routes have been altered to open up the
viability of laying back and restoring the shoreline.
