The goal of Kirkland's annual street preservation program is to keep the City's 600 lane miles of roads in conditions that are cost-effective to maintain and functional for travel. To achieve this, Kirkland repairs and conditions roughly 40 lane-miles of roads every year.
Thirty of these lane-miles are on residential and collector streets, which connect residents' homes to the City's arterials.
Kirkland repairs and conditions more than 10 lane-miles of arterials, which are the City's most traveled class of roads. The primary method of repairing arterials is to repave them. Engineers call this 'overlay.'
SLURRY SEAL (sealing)
Typically, the City treats approximately 30 lane miles of neighborhood and collector roads every year. The primary method of treatment for these roads is a thin layer of a mixture of emulsified asphalt, aggregate and water. Engineers refer to this as slurry seal. Slurry seal can restore roads to near optimum condition for as little as $1,600 per City block. However, they do not provide structure to the road. As such, Slurry Seal is not effective for deteriorated roads.
