Sauk Prairie Road / Everett Creek Culvert Replacement


Snohomish County is proposing to replace an existing culvert with a larger concrete box culvert on Sauk Prairie Road near Darrington to alleviate drainage problems. The project location is approximately half a mile east of the intersection with Crawford Loop Road. Several hundred feet of the roadway will be raised to accommodate the new culvert, eliminating water on the road and improving fish passage.


  • Project design is expected to be completed in 2019
  • Construction is expected to begin in the summer of 2020 and have a duration of 3-4 months.

Traffic Impact

During construction, a full road closure will be required. Drivers will be detoured via Crawford Loop Road.


The project is funded by the Snohomish County Roads Fund and construction is expected to cost approximately $1 million.

Environmental Review

An environmental review and SEPA Checklist were completed for the proposed project in compliance with the State Environmental Policy Act (SEPA) on April 19, 2017.  Snohomish County Public Works determined that this project does not have a probable, significant adverse impact on the environment and has issued a Determination of Non-significance (DNS) on April 21, 2017.
