What’s happening now?
We will soon reseal some neighborhood streets with a thin layer of asphalt mixture called a slurry seal. We spread this material over the street to help it last longer.
During the work, we will temporarily close streets, remove on-street parking, and may temporarily affect access to businesses and driveways.
The Slurry Seal reseal project will take place on selected streets in northeast and south Seattle (see maps below) in July and August. Construction dates are subject to change, and some of the streets may change.
The slurry seal process takes about a day (approximately eight hours). During this time, cars cannot drive on the road while the slurry mixture dries.
Project Area
The map below show the streets that will be treated this year. No Parking signs will be installed prior to construction. Please note that these are preliminary maps and locations are subject to change.
What to Expect:
On the day of the slurry seal,
- You won’t be able to drive, park, or walk on the new street surface for up to eight hours.
- If your car is parked on the street when we start work, your car will be towed.
- Our crews will begin preparing for work and talking with each other before 7 AM.
- You'll also notice large trucks and machines coming, going, and being used close to your house. There’ll also be noise, dust, and probably vibrations.
- You should plan to use an alternate way around your neighborhood.
Here’s what you will need to know about the work:
- If the street in front of your house has no sidewalks, the slurry seal only goes to the edge of the street.
- Pedestrians and pets should keep off the slurry seal material until the street is reopened for traffic. The uncured material is difficult to remove from clothing, shoes or paws.
- If you are conducting private construction that may impact the road, please complete that ahead of our project.
- If your street is scheduled for work on your garbage or recycling pick up day, we will coordinate an early pick up.

About the Slurry Sealing Process
A slurry seal is a thin layer of asphalt mixture spread over a street to protect it and make it last longer. It fills small cracks and smooths the surface, kind of like putting a fresh coat of paint on a wall to seal and protect it. Slurry seal is used on streets that are still in pretty good shape to prevent bigger damage later.
As shown in this short video, as the slurry seal equipment moves along the street, the mixture is fed into a spreader box. The material is spread across the full width of a traffic lane and then smoothed out. The equipment also feathers the edges for a smooth transition. All this happens in one step.
After the seal coat dries, we reopen the street and return it to normal use. However, parking restrictions and road closures may remain in place for the full day the work is scheduled.
We do we resurface streets that look fine?
Flexible pavements (typically asphalt) need periodic resealing to protect them from the deteriorating effects of water (rain) and sun. If left untreated, the street surface becomes brittle and may crack and ravel. Periodic resealing prevents more extensive and costly repairs. Regular preventive maintenance is the most cost-effective way to maintain streets.
Preparing the street: fixing potholes, cracks, etc.
It is essential that structural damage is repaired prior to the slurry seal process. SDOT crews will begin to patch deteriorated areas of the selected roads well in advance of the slurry seal operation. In addition, low hanging branches and overgrowth may need to be trimmed to allow for the slurry seal equipment to navigate the roads. Prior to the day of slurry sealing, crews will sweep the street before applying the slurry seal material.
