Additional Services Agreement No.
Green River Trail at Tukwilar i a y rd Bank ErosionRepair
File 0259-062-01
This confirms Additional Services Agreement (ASA) Number 2 between KPG Psomas, Inc. (KPG Psomas) and
GeoEngineers, Inc. (GeoEngineers) for continued Mitigation Permitting Services for the City of Tukwila (City) Green
River Trail at Tukwila International Boulevard Bank Erosion Repair Project located in Tukwila, Washington. The
project is currently in Mitigation Development phase and the use of King County In -Lieu Fee (ILF) mitigation credits
from the Chinook Wind Mitigation Site has been identified as the preferred mitigation path to offset impacts
associated with the trail scour repair project. We have prepared this ASA to prepare an ILF Use Plan Report
documenting use of the Chinook Wind ILF credits; accommodate additional mitigation coordination already
completed as well as coordination anticipated during preparation, submittal and review of permit application
materials; and include local (City) permitting that will be needed for project approval. Our scope, assumptions and
fee estimate are included below.
This task amends existing Task 2 that was previously authorized to add the following additional services:
1. Additional coordination with City and KPG Psomas previously completed during evaluation of mitigation
alternatives, selection of a preferred mitigation alternative and preparation of associated documentation.
2. Additional coordination meetings with external stakeholders and fishery co -managers (Washington Department
of Fish & Wildlife [WDFW] and Muckleshoot Indian Tribe Fisheries Department [MITFD]) previously completed
to present mitigation alternatives and recommendations.
3. Anticipated coordination with the City, KPG Psomas, WDFW, MITFD, U.S. Army Corps of Engineers (USACE)
and/or King County Mitigation Reserves Program during development of the ILF Use Plan, permitting
documentation and permit application submittal/review processes.
4. Associated project management during the course of execution of the above services.
KPG Psomas, Inc. I September 6, 2024 Page 2
This task amends existing Task 4 that was previously authorized to add the following additional services:
1. Prepare an ILF Use Plan documenting use of the Chinook Wind ILF credits as mitigation for the proposed project.
2. Prepare a State Environmental Policy Act (SEPA) Checklist.
3. Prepare a Shoreline Narrative addressing compliance with the City Shoreline Master Program (SMP).
4. Act as authorized agent on behalf of the City for WDFW and USACE permits. This will include submittal of
Hydraulic Project Approval (HPA) application through WDFW online portal and Section 10/404 Clean Water Act
(CWA) permit application electronically to USACE.
Contract will be extended to December 2025. All services included in this amendment are anticipated to be
completed within this timeframe and our estimates associated with anticipated coordination and general
project management during execution of these services are based on this assumption.
We have accounted for up to 16 hours of anticipated coordination in this amendment. If the project timeline is
extended or other unforeseen circumstances require additional coordination above and beyond this allocation,
an amendment to this scope and fee estimate may be required.
The ILF Use Plan will be based roughly on the examples provided by King County. The ILF plan will be provided
as a draft for KPG Psomas and City review and then finalized for submission to the USACE and Interagency
Review Team (IRT). We have not currently budgeted for any further revision based on USACE or IRT review.
• Figures to be included in the ILF Use Plan will be provided by KPG Psomas.
• DARPA form and Biological Evaluation (BE) were included in previously contracted scope of services and will be
used to submit applications to USACE and WDFW.
• SEPA Checklist, JARPA form (included in original scope of services) and Shoreline Narrative will be provided to
KPG Psomas and the City for City use completing internal permit applications.
• A shoreline permit will be required and will also be used to document compliance with City critical areas
regulations. A separate approval for critical areas is not anticipated.
Shoreline stabilization and public paths are permitted uses within the Urban Conservancy shoreline
environment and within the shoreline buffer; shoreline stabilization is a permitted use within the Aquatic
shoreline environment. The project will be approved as a Shoreline Substantial Development, if not exempt as
normal maintenance and repair. A variance or conditional use permit will not be required.
The ILF Use Plan and purchase of ILF program credits will be sufficient mitigation and documentation to meet
all agency requirements, including the City for Shoreline permit; additional mitigation for shoreline approval is
not anticipated or included.
A cultural resources survey and critical areas report are not included and will not be required by the USACE or
the City.

Green River Trail at Tukwila International Boulevard Bridge Bank Repair
GeoEngineers
Scope of Work
Amendment No. 1
February 23, 2023
GeoEngineers, Inc. (GeoEngineers) is pleased to present our scope of services for additional environmental
permitting supportfor the proposed Green RiverTrail at Tukwila International Boulevard Bridge Bank Repair
project in Tukwila, Washington.
Our understanding of the project is based on the following work we completed during the initial phase of
the project:
uuuum Teleconference meeting with the City of Tukwila (City), Muckleshoot Indian Tribe (MIT), Washington
Department of Fish and Wildlife (WDFW), and KPG Psomas, Inc. (KPG Psomas) to discuss permit
processes and mitigation requirements, held on December 5, 2022.
uuuuim Teleconference meeting with the City and KPG Psomas to discuss scoping and objectives, held on
January 4, 2023.
uuuui A site visit on February 8, 2023, to review site conditions, identify baseline habitat conditions, quantify
habitat impact areas by type and identify nearby/adjacent mitigation opportunities.
We understand the City would like us to proceed with documentation of potential habitat impacts that would
result from the project and use this as a basis for identifying commensurate mitigation amounts and types
that could be used to satisfy permit agency and tribal requirements. The objective of this work is to place
bookends on the type and amount of mitigation that would be appropriate to offset the project impacts and
to preliminarily identify potential mitigation sites that may meet this objective. This information would be
presented to stakeholders and permit agencies for acceptance as a path forward forthe projectto progress.
Following successful acceptance of the approach by stakeholders, we will develop a mitigation commitment
memorandum and develop and submit permit applications for the repair of the Green River Trail along the
Duwamish River. Based on prior communication with WDFW and MIT, it is acceptable to permit the bank
repair using a mitigation commitment, with implementation of the mitigation to follow. Advancement of
mitigation site design and implementation of mitigation, including additional permitting, will be developed
as a future scope amendment once the site has been selected.

Subject: Geotechnical Design Services — Green River Trail Repair under Pacific Highway
Bridge, Seattle Washington (Schnabel Reference 22154011.00P)
Dear Mrs. Anderson:
SCHNABEL ENGINEERING, LLC (Schnabel) appreciates the opportunity to submit this proposal for
professional engineering services for the referenced project for KPG PSOMAS Inc (KPG). This proposal
has been prepared in response to your request on September 28, 2022.
PROJECT DESCRIPTION
This project consists of repairing Green River Trail that has been eroded by the Duwamish River over a
trail length of 16 -ft. The repair is located under the Pacific Highway Bridge (Tukwila International Blvd)
along the south embankment of the Duwamish River. This portion of the existing Green River trail located
below the bridge consists of asphalt paving on gravel backfill and is built on backfill retained on the river
side by either a sheet pile wall or old timber supported concrete pier 1 pile cap that was left behind during
construction of the Pacific Highway Bridge. The portion of the trail that has eroded occurred in the 16 -ft
gap between the sheet pile wall and old pile cap.
OBJECTIVE AND SCOPE OF SERVICES
The objective of our services is to assist KPG with the development of engineering documents required to
successfully repair this section of the Green River Trail. Schnabel's scope of work is to provide both
temporary and long-term trail repair solutions. The long-term solution should consist of a system that will
support the trail during future high-water level events in accordance with local code.
We propose to furnish the following services in connection with this project.
Task 1 — Site Visits
We will conduct two site visits to take field measurements and observe the current status of the eroded
trail. We will coordinate our activities with KPG and City of Tukwila (City). It is anticipated that each visit
shall take no more than 3 hours each. The first visit will occur immediately and will be focused on
temporary repairs, while the final site visit will focus on the long-term solution.

Task 2 — Conceptual Alternatives Analysis Memo
We will perform a conceptual alternatives analysis for long-term stabilization for the City's consideration.
Schnabel may submit a request for additional information to the City, if need be. The number of
alternatives that will be provided for long-term stabilization will be limited to a maximum of 3.
This task includes the following:
• Data review - we will perform a review of existing engineering documents, including the Existing
Bridge Plans and Geotechnical Reports.
• Conceptual Alternatives Memo - a memo will be provided to the City summarizing our data review
along with a summary of conceptual alternatives for long-term stabilization. Additionally, a
summary of the temporary stabilization methods will be included for the City's selection.
• Project Coordination: We will coordinate with KPG and the City as needed and includes attending
a meeting either at the City of Tukwila premises or via video conference after the City has
reviewed the conceptual alternatives memo.
Task 3 — Temporary Stabilization Recommendation Memo
Once the project team has selected a preferred alternative for long-term stability, Schnabel will compile a
brief memo to provide direction to Titan Construction for the selected temporary slope stabilization
alternative. This task does not include construction documents.
Task 4 — Hydraulic Review and Scour Potential
Schnabel will review available documents such as FEMA Flood Insurance Studies and available data
such as USGS gages. We will use this information in conjunction with the available 1996 Geotechnical
Report for the existing Pacific Highway Bridge to evaluate scout potential and develop options for
remediation. This may include riprap sizing based on an estimated river velocity.
Task 5 — Long-term Stabilization Design
The long-term stabilization conceptual design alternative selected by the City will ultimately determine the
number of hours required to complete the design. The hours provided herein are general and may require
refinement after the City selects a conceptual design.
We will provide one electronic calculation submission package consisting of calculations and a drawing
set with technical notes signed and sealed by a Professional Engineer registered in the State of
Washington.
ASSUMPTIONS
In developing our scope, we have assumed the following:
• Design services will be based on existing geotechnical information as shown on the Existing
Bridge Contract Documents. We cannot comment on the accuracy of this data.
• The top of the lateral soil support will match the top of the existing pier 1 pile cap.
• Overtopping of the lateral soil support, by the river and the resulting damage to the trail, is not a
design consideration, since the height of the proposed lateral soil support will match the height of
the existing pier 1 pile cap.
