(Aug. 27, 2019) --
NE 97th Street from Slater Avenue NE to 124th Avenue NE will be treated with slurry seal on Wednesday, Aug. 28 instead of Aug. 27. The contractor was unable to complete this street by the end of the day on Tuesday.
(Aug. 22, 2019) --
Thursday's morning drizzle forced Kirkland's 2019 slurry seal contractor to reschedule to Wednesday, Aug. 28 all but two of the streets it had planned to slurry seal on Aug. 22.
Intermountain Slurry Seal did slurry seal 125th Avenue Northeast, between Northeast 100th Street and Northeast 101st Place, as well as Northeast 101st Street, between 125th and 126th avenues northeast.
This is Intermountain Slurry Seal's third schedule change; the second due to weather. The schedule remains in tact for Friday's streets.
Intermountain Slurry Seal is preserving more than 40 sections of neighborhood streets in Kingsgate, North Rose Hill and South Rose Hill, which will add five to 10 years of useful life to the streets.

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.
