Slurry Seal

A Slurry Seal is an economical approach to preserving pavement conditions on heavily traveled local roads that the City of Bothell began utilizing in 2018. This method is expected to provide five to ten years of improved pavement condition.

What to Expect


The contractor will maintain access for local residents, mail delivery, garbage pick-up, and emergency vehicles. 

There will be parking restrictions from 8:30 am - 4 pm. "No Parking" signs will be posted in advance. Residents who will need to drive in the area on the roadway after application should park on unaffected side streets in advance. You will not be able to drive on the roadway for 4-6 hours. Residents can expect to see mailers and on-street signage with more information prior to construction. 


After Slurry Seal is applied, the surface of the road will be a bit rough. The contractor will sweep streets several times to remove loose rocks. The rough surface will smooth out with traffic, weather, and sweeping.
