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. Project Budget Phase 2025 CWM Grant $ 618,324.00 Final Design & Construction King County Parks OSRC Grant $1,000,000.00 Construction & Construction Mgmt Total $1,618,324.00 RECOMMENDATION Council is being asked to accept a 2025 Cooperative Watershed Management grant award for the Chinook Wind Extension project in the amount of $618,324 and consider this item on the Consent Agenda at the November 3rd, 2025 Regular Council Meeting.

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.
