Sauk Prairie Road / Everett Creek Culvert Replacement


Snohomish County is proposing to replace an existing culvert with a larger 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. The new culvert will be installed at the low point of the road so that Everett Creek can pass under the roadway. Seven hundred feet of the roadway will be raised to accommodate the culvert, eliminating water on the road and improving fish passage.


  • Project design is expected to be completed in 2019
  • Construction is expected to be completed 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 Permitting and Regulations 

The project will require federal, state and local permits and approvals. To comply with the State Environmental Policy Act (SEPA), an Environmental Checklist has been prepared and a Determination of Non-Significance issued. These documents are provided below, along with a vicinity map.
