SUBJECT: Surface Water Fund — Chinook Wind Extension
Project No. 92341202 - 2025 King County Parks Open Space -River Corridors (OSRC)
ISSUE
Accept a 2025 King County Parks Open Space -River Corridors (OSRC) Grant for $1,000,000 to fund
the construction of the Chinook Wind Extension project.
BACKGROUND
In April 2025, staff applied to the King County Parks OSRC grant program to fund the construction of
the Chinook Wind Extension project. The OSRC grant program supports projects that improve the
natural function of rivers, public access, and/or awareness of river corridors as valuable natural
resources.
DISCUSSION
In July 2025, staff were notified of a $1,000,000 award. 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 $1,000,000 from the OSRC program. No local match is required. The City also
was awarded a $618,324 grant from the King County Flood Control District Cooperative Watershed
Management program to supplement this OSRC 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 Phase 2 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
2025 CWM Grant $ 618,324.00
King County Parks OSRC Grant $1,000,000.00

December 1, 2025 Regular Council Meeting.

Project # 92341202
Department Surface Water
Following the Public Works Facility Preferred Master Plan (2019) and the Duwamish Gardens Opportunities
for Expansion Concept Plan (2013), this project will develop connecting shoreline habitat and the 'missing
trail link' between Duwamish Gardens and Chinook Wind within recently acquired City property.
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 shorelinetrail.
The project is cure
ntly t 50% design.
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 grantfunded project is being implemented as part of thePW 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,
