Updated: Decener 2, 2024

What's Happening Now?

We’re thrilled to share the latest developments on the Willow's Creek Project! Here's what we've accomplished and what's coming next:

Recent Milestones Achieved:

  • The stream bed of the creek has been fully completed, and water is now flowing beautifully back into the stream channel. 💧
  • Our crews have started work on installing vegetation and landscaping to revitalize the area.
  • We’re adding the finishing touches to roadway and surrounding infrastructure.

What to Expect Next:

We’re working hard to deliver substantial project completion by the end of the year. Please note that temporary parking restrictions may be in place as crews finalize paving, so keep an eye out for signage in the area.

We truly appreciate your patience and cooperation as we bring this project to life. Willow's Creek is on its way to becoming a vibrant and welcoming space for everyone to enjoy! 🌿

Project Background

In summer of 2021, The Seattle Department of Transportation (SDOT) completed construction of the Northgate Pedestrian and Bicycle Bridge over I-5 in the Northgate neighborhood of North Seattle. The Bridge runs over and through the North Watercourse, which is a tributary to the South Branch of Thornton Creek. The Bridge project has impacted the North Watercourse by decreasing habitat and retaining the barrier to fish passage.

Upon completion of this project, we chose to mitigate for these impacts off-site at Willow Creek, which is located at NE 100th Street near Lake City Way. The proposed changes consist of re-routing the creek and removing two culverts, one of which is currently a partial blockage to fish passage.
