Water was flowing over the sidewalk during the winter at the intersection of 77th Ave SE and 132nd Pl SE, as a result of a seasonal perched water table. The Project installed an interceptor trench behind the sidewalk to intercept the ground water and convey it away from the sidewalk and connect to a nearby existing drainage system.
Schedule
Construction was completed in 2016 by Snohomish County Road Maintenance crew.
Traffic
