Street Resurfacing Coming This Summer

City of Mukilteo Street Resurfacing Flier


The City of Mukilteo maintains 61 centerline miles (124 lane miles) of roadway within the City limits. Slurry sealing is one of many effective tools in the City’s preventative maintenance program and is typically applied to streets that are in fair to good condition. Slurry seals prolong pavement life by applying a thick, cold liquid mixture of asphalt and rock to the existing pavement surface. In general a Slurry Seal extends the pavement life by 5 to 10 years. Slurry seals are less expensive than typical asphalt overlays, but take longer to thoroughly cure (or dry) before the street can be reopened to traffic.

What to Expect:

Phase One

The contractor will arrive onsite to seal cracks in the roads and repair small areas of damaged pavement.

Residents are asked to prune back their vegetation to allow maintenance vehicles to get next to the curb. All lower growing plant material should be pruned back behind the curb, and all trees are required to be trimmed to provide a 14-foot vertical clearance from the road surface.

No road closures will occur in this phase, however temporary delays may occur.

Phase Two

As the date of the actual slurry seal application gets closer, work crews sweep pavement surfaces and remove any vegetation that infringes into the right-of-way. Crews will make final repairs to pavement surfaces.

Roads will remain open to traffic, however temporary delays may occur.

Phase Three

Work crews notify residents at least one day prior to slurry seal’s application. Residents remove all motorized vehicles, and personal items from the road. Residents don’t water their lawns or wash their cars. Work crews apply slurry seal to the street. This is a one day process that requires a one-day road closure. When the slurry seal is first applied, the material is brown and sticky. To prevent damage to the fresh slurry and avoid tracking, cars, bikes, people, and pets must be kept off the street until the seal is cured and the street is reopened. After the curing process is completed, the barricades and signs wall be removed showing the road is reopened.

Phase Four
The new road surface has more friction and sheds some of the finer aggregate, creating a sandy surface. Work crews will return to sweep the streets approximately one and three weeks after application.
