UPDATES & INFORMATION

-- Late-summer’s unusually wet weather has forced Kirkland to postpone until spring 2020 the paving of 116th Avenue Northeast, between the Houghton Park and Ride and Northeast 73rd Place.

The City of Kirkland repaves up to 10 lane-miles of its more traveled streets every year. The Capital Improvement Program pays for about half of those lane-miles. The other half is funded by the 2012 Streets Levy.
Repaving a street can extend its useful life by 10 to 20 years, at an estimated cost of $49,000 per block.
2019 Overlay Program
Kirkland will be repaving sections of streets this summer in six different neighborhoods. Those street sections are included in the sidebar and map thumbnail in the sidebar on the right.
The process this year begins in July with a process known as "lowering iron
," during which workers remove utility lids to prevent the damage they would otherwise sustain during the grinding stage.
The grinding stage
is when contracted crews use milling machines to remove the top three to five inches of a street's a
sphalt. Once crews have removed the street's damaged layer of asphalt, they are ready--assuming good weather--to lay down its new asphalt surface.
Kirkland's goal for its street preservation program is to improve the score of its arterial network to 70 on the Pavement Condition Index. The street network's Pavement Condition Index score at the end of 2015 was 65.4. In 2018, it was 70. Some of that improvement, however, can be attributed to a change in how the City measures its street conditions.
A repaved street would score 100 on the index. A street riddled with potholes and alligator cracks would likely score lower than 50. Streets that score lower than 50 usually require total reconstruction, which costs taxpayers $165,000 per City block. The City of Kirkland rarely reconstructs roads due to that expense.
