280th St NE Culvert Replacement 


Snohomish County is proposing to replace two culverts under 280th St NE, northwest of Arlington. The existing culverts are deemed fish-passage barriers. The new box culverts are designed to meet fish passage standards.


Construction is expected to begin on July 15, 2022 and end mid-September. Construction crews will be working Monday – Friday during daylight hours.

Traffic Impact

During construction there will be single-lane closures. Emergency services will be notified and able to get through the project area.


This project is estimated at approximately $1.1 million and is funded by Surface Water Management Utility fees.
