BACKGROUND The goal of the Stormwater Outfall Water Quality Retrofit program is to improve the water quality of stormwater discharges to the Green-Duwamish River from city roads. This project will retrofit four city street discharge points out of eight that were prioritized by City staff. In a prior contract, Psomas analyzed and ranked these eight discharge points based on seven criteria and also developed designs for these four priority sites to 90% Plans. The first two sites were constructed in the fall of 2024 and summer of 2025, one on Interurban Avenue S and the other on Tukwila International Blvd. The first contract amendment was a time extension only, and the second amendment added final design and construction management funding for the next two sites to be built in 2026, one on East Marginal Way and the other on Fort Dent Way. DISCUSSION Amendment No. 3 includes additional funding for construction management services ($56,268) for the first two sites and funding for utility potholing ($42,000) for next two sites. FINANCIAL IMPACT This amendment totals $98,268, 85% is reimbursable through two Department of Ecology (DOE) Stormwater Financial Assistance Program grants. The first DOE grant (WQC-2023-Tukwil-00073) will fund the construction management services ($56,268), and the second DOE grant (WQC-2025-Tukwil- 00039) will fund the utility potholing ($42,000) for the second two sites. Budgeted CIP Surface Water revenue in the amount of $63,171.15 will cover the required 15% match for both grants.

The City of Tukwila has been selected to receive funding through DOE Agreement No. WQC-2023-Tukwil-00073 ("Grant Agreement") in the State Fiscal Year 2023 (SFY23) Funding Cycle. The work includes: Site 1: Tukwila International Blvd at SR 599 Off -Ramp Install two new modular wetland units, storm conveyance pipe, and restoration of gore area to treat stormwater runoff before it outfalls to Riverton Creek. Site 2: Interurban Ave S at 58th Ave S Install new modular wetland unit, storm conveyance pipe, and street trench restoration to treat stormwater runoff before it outfalls to the Duwamish River. This location will also be replacing existing signalized intersection loops with permanent video detection. A detailed scope follows: I. INTRODUCTION Shortly before construction began for the project it was discovered there were additional requirements for completing the work at the SR 599 Off -Ramp due to the work being in WSDOT Limited Access Right -of - Way. The Contractor intended to start work at this site, but had to shift work to the Interurban site until the requirements of WSDOT were met. This caused a delay in the project starting and forced the project into splitting the work into two construction seasons. A complete list of items that extended the project scope and time to completion are as follows: • Unexpected WSDOT coordination caused scope and time increases o Structures installed within the WSDOT ROW had to be stamped by the Materials Lab, requiring additional coordination time. o The 35 working days were split between Fall 2024 and Spring 2025 creating additional time administrative items required by the Contract. o WSDOT coordination continued through the winter months to resolve their requirements for the WQ vault yet to be installed within their limited access right-of-way. o Certified payroll tracking continued through the suspension period. City of Tukwila Stormwater Outfall Water Quality Retrofit Project Construction Management Services Page 1 of 7 Psomas June 19, 2025 9 EXHIBIT A-5 • The Contractor's vault supplier had delays in shipping the items to site. This forced the Contractor to pave on two days instead of one for the Interurban site. Increasing the amount of testing required. • New crushed rock and HMA materials were submitted for the work to be completed in the spring, which required additional conformance testing. • An unmarked conduit was discovered running through a section of the project. There were four non -working days associated with this discovery as the Contractor lost efficiency and was working on non -critical items during this time. • Additional non -working days were granted for weather. Some work continued on these days but was inefficient. General Assumptions: • There are 15 working days remaining in the Contract. Work is expected to wrap up within this time, except for punchlist items. • Coordination with WSDOT will continue as work progresses within their ROW. • The proposed project team will include a part time Resident Engineer (10 hours a week), one full time Construction Inspector, a part time Documentation Specialist (20 hours a week), and one part time Project Engineer from Psomas's design team to review submittals and interpret Contractor inquiries, as needed. The team also includes a sub -consultant to provide services for materials testing and construction site observation to satisfy Tukwila Municipal Codes for work within certain soil classifications. • Consultant will coordinate during audits or traffic control operations related to project impacts and help the City to complete any other required correspondence with outside agencies. • Psomas design engineers will be available during construction to answer questions and review RAM's, shop drawings, and answer RFI's. • Consultant services will be performed in accordance with the WSDOT Construction Manual, Contract plans & special provisions, and City of Tukwila engineering standards. • The franchise Utilities will provide field inspection for all work surrounding the construction or relocation of their utility systems if necessary. • Coordination of construction with franchise utilities, if any, will be done by City Contractor. Consultant will help facilitate coordination between utilities and Contractor as needed or requested by City.

BACKGROUND In February 2025, staff applied to the CWM grant program to fund the final design and construction of the Chinook Wind Extension project. The CWM grants are intended to recover ESA -listed salmon species and restore watershed ecosystems. DISCUSSION In August 2025, City staff received notification of a $618,324 award for Chinook Wind Extension final design and construction. This project seeks to complete the "missing link" public access trail between the recently completed Chinook Wind Mitigation Site and Duwamish Gardens. This project will also create complimentary off -channel habitat that will be utilized by juvenile Chinook, contributing to species recovery efforts. FISCAL IMPACT The City will receive $618,324 from the CWM program. No local match is required. The City also was awarded a $1,000,000 grant from the King County Parks Open Space -River Corridors program to supplement this CWM funding for Construction and Construction Management. The total cost for the Chinook Wind Extension project has increased in part because the project was separated from the larger Public Works Shops project. This separation requires additional coordination with King County and other stakeholders, resulting in more staff and consultant time during the design phase before the project can advance to construction.

This is a Tier 1 project in the WRIA 9 Salmon Recovery Plan, fulfilling a core recovery strategy of restoring, protecting and enhancing estuary habitat in the Duwamish River. The trail connection has been discussed in the community for many years and is anticipated to be part of larger, popular shoreline trail. STATUS: The project is currently at 50% design, MAINTENANCE IMPACT: COMMENT: FINANCIAL (in thousands) This is a work in progress. The Green Infrastructure Program Proposal is intended, in part, to address maintenance 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 matures. 3 years is considered a rule of thumb for plant establishment. This grant funded project is being implemented as part of the PW Shops Ph 2 project. There are expectations by the granting agency that the project will be constructed. It is the middle link of the Duwamish Gardens/Chinook Wind trail and "blue belt" aquatic restoration corridor. 2025 2026 2027 2028 2029 2030 Beyond TOTAL Project Costs Project Mgmt (Staff Time/Cost) Design Construction Mgmt.

BACKGROUND In June 2024, Staff applied to the SRTS program to fund community outreach and design phases of the project. The purpose of the SRTS program is to improve safety and mobility for children by enabling and encouraging them to walk and bicycle to school. DISCUSSION In August 2025, City staff were notified of a $610,000 award. This project is intended to improve active transportation and safety for students at Thorndyke Elementary, Showalter Middle, and Foster High Schools. The study area is 46th Ave S from S 150th St to S 144th St, with the goal of providing a safer walking path. Project activities include community engagement, land/geotechnical survey, traffic engineering studies, permitting, preliminary engineering, and right-of-way acquisition, if necessary. The design phase budget has increased above the CIP amount primarily because the original estimate is outdated and did not reflect current conditions or the full scope of work now anticipated. As we evaluated the project in preparation for the federal grant application, we identified that some right-of-way acquisition will likely be needed, which adds to the design cost. In addition, federally funded projects require additional documentation, review, and coordination, which increase consultant and staff costs. We have also included a budget for community outreach and engagement to ensure robust public involvement throughout project development. FISCAL IMPACT The City will receive $610,000 from the SRTS program. No local match is required. Funding from this program is limited to projects within two miles of primary, middle, and high schools. The updated design budget covers work planned for both 2026 and 2027.

Th e Annual Surface Water Management Plan specifies a NPDES reporting and action plan for City compliance. The services/supplies funds will also include any illicit discharge (spill cleanup) costs that may occur in the City's right-of-way. State Mandated Permit "National Pollutant Discharge Elimination System (NPDES) Phase ll Western Washington", Federal Clean Water Act and Additional State Waste Discharge Permit RCW 90.48. NPDES requirements are ongoing with new permit requirements every 5 years (2024-2029). Requirements cover all divisions of the city including Public Works, Golf/Parks, Police, Planning, and Facilities. Costs shown include emergency supplies, testing equipment, Lab testing fees, and annual consultant support. Added requirements require changes to conform with NEW requirements, e.g. New Inspection and street sweeping requirements will require more staff time to complete and document as well as new equipment and supplies. STATUS: Currently Compliant with new permit updates in the planning phase. MAINTENANCE IMPACT: COMMENT: FINANCIAL (in thousands) The City is typically granted Capacity Grant funds to cover much of the coordination expenses and some of the additional expenses. Each division should track costs incurred to manage pollution such as spill kits, staff time for surface water pollution prevention inspections on qualifying city facilities and during field operations within the jurisdiction. This cost is not accounted for in the impact cost above. In addition to the NPDES permit, there are specific actions undertaken to assist in the Lower Duwamish Superfund compliance effort, such as source control inspections, PCB investigations and discharge responses. 2025 2026 2027 2028 2029 2030 Beyond TOTAL Project Costs Project Mgmt (Staff Time/Cost) Design Planning $ 72 $ 200 $ 72 $ 72 $ - $ 72 $ 72 $ - $ 72 $ 72 $ - $ 72 $ 72 $ - $ 72 $ 72 $ - $ 72 $ 86 $ 86 $ 518 $ 200 $ 518 Total Project Costs $ 344 $ 144 $ 144 $ 144 $ 144 $ 144 $ 172 $ 1,236 Project Funding Proposed Grant Utility Revenues $ 279 $ 130 $ 79 $ 79 $ 130 $ 79 $ 79 $ 130 $ 79 $ 79 $ 390 $ 753 Total Project Funding $ 279 $ 209 $ 79 $ 209 $ 79 $ 209 $ 79 $ 1,143 28
