The 2018 slurry seal schedule continues to change daily, due to the contractor's on-going mechanical challenges. The maps above reflect the most up-to-date schedule. Please check this website regularly for updates.
Update (Aug. 13, 2018) -- The City of Kirkland suspended the balance of 2018’s Slurry Seal Program after a series of setbacks suffered by the contractor stretched the original four-day schedule into a second week of uncertainty. “Our residents need the certainty to know on which days we are closing their streets for preservation,” said George Minassian, Kirkland’s streets engineer. “Unfortunately, a few circumstances made it impossible for us to do that. The good news is that this delay should not result in significant deterioration of the roadway surfaces that were not treated this year.”
One of those circumstances happened on the first day, when two of the contractor’s three specialized vehicles broke down. The contractor, Intermountain Slurry Seal, was able to repair one of the vehicles but not the other, resulting in unpredictable schedule delays. Another circumstance that prevented the contractor from getting the work done on schedule was the contractor’s inability to supply sufficient quantities of the specified materials needed to make the slurry seal. These circumstances have led the City to suspend any further work until next year.
The contractor has completed 29 of the 48 streets the City originally planned to seal in 2018. This week, the contractor will begin the required sweeping and clean-up activities for those completed streets. The contractor will sweep again one month and three months from now. Intermountain will also re-paint all street markings on all 48 streets later this summer. The City intends to secure a contract to complete the unfinished streets in 2019.
The City’s street paving (overlay) program continues to be on schedule.

Kirkland extends the optimal life of neighborhood streets every year by applying a slurry seal to their surfaces.
This quarter-inch layer of water, aggregate and emulsified asphalt--oil--shields the pavement beneath it from weather and replenishes that pavement with new aggregate.
These functions can extend roads’ good conditions for five to 10 years. And all it costs is $1,600 per city block, compared to the $17,000 per city block it costs to repave a road or the $65,000 per block it costs to rebuild a road.
The cost-effectiveness of slurry seal is why thousands of municipalities throughout the nation use it and why the City of Kirkland has used it in every neighborhood throughout the City since 2002
These benefits, however, can be hard to see in the first few weeks after the streets first receive slurry seal. Initially, the surface is gritty
, where it was once smooth. This initial grit is normal. But it is not permanent.
The first phase of your street’s transition toward smoothness is the street sweeping, which removes all of the loose gravel. This occurs approximately one week, three weeks and three months after application. The second phase of that transition is more subtle. And its main ingredient is time.
Over time, automobile traffic will dislodge the larger, sharper pieces of aggregate that initially give the road its rough, gritty surface. Traffic will also push the remaining aggregate deeper into the surface.
Within a year or so, the smooth road residents remember before slurry seal will be back—with an extra five to 10 years of high-quality life infused into it.
2012 Streets Levy
The 2012 Streets Levy is doubling the number of lane miles the City of Kirkland can slurry seal each year. Kirkland has a goal of treating every residential street in the City with slurry seal by the year 2032.
