Slurry Seal

Click on the maps above to see which residential streets in the Finn Hill, Houghton and Norkirk will receive slurry seal in 2017.

UPDATES & INFORMATION

FIRST-sewer-city-hall-constructionUpdate
(Aug.10)  -- Kirkland’s 2017 slurry seal contractor will start closing more than 40 sections of residential streets on Aug. 11 in the Finn Hill, Norkirk and Houghton neighborhoods.

Telfer Technologies will close each of these road-sections for one business day while its crews treat it with slurry seal.

Telfer Technologies will apply slurry seal to 26 Finn Hill street-sections on Aug. 11, 14, 15, 16. The contractor will treat 11 sections of Norkirk’s residential streets on Aug. 11 and 16.

And in Central Houghton’s Sandhurst development, Telfer Technologies will be working Aug. 15 and 16. “The schedule is can change for a variety of reasons, such as rain, or even a forecast of rain,” said George Minassian, Kirkland’s streets engineer.

Last week, a mistake by the printing and mailing shop led to Finn Hill residents receiving the slurry schedules for Houghton streets and Houghton residents receiving the slurry seal schedules for Finn Hill streets. The printing and mailing shop will re-send the updated postcards to the correct recipients, at its cost.

“The website had the correct schedules for each neighborhood,” Minassian said. “But if you didn’t check the website, you might have discarded the postcard with the assumption that your road wasn’t going to close, when, in fact, it is. We want to make sure residents are ready and prepared for slurry seal.”

SLURRY-2016-project-update-follow-up-imageKirkland 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.
