Advance Mitigation Site at Little Bear Creek


Snohomish County Public Works acquired four parcels of land in the lower Little Bear Creek Watershed near Woodinville. The 17 acres acquired will be used as part of an advance mitigation effort.

This effort is to restore wetlands and stream habitat on the site, preserve other areas, and enhance some areas to compensate for impacts associated with future roadway projects.

Restoration construction consists of site grading to create and restore wetlands, remove impervious surfaces and an internal roadway, remove debris and underground utility pipes, and install large woody debris for stream restoration.


  • 2019: Demolition of the buildings were completed
  • Summer 2022: Restoration Construction
  • Fall 2022: Install more than 21,000 native plants

Traffic Impact

There will be single-lane closures at the intersection of 238th St SE and 58th Ave in July. Crews will be re-grading the adjacent hill, to improve site distance.


  • Funding for this project is provided by the Snohomish County Road Fund.
