Drainage Improvements near 13007 77th Ave SE

Description - Completed 2016

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

Signage and traffic control was provided to route traffic around the construction site. No full road closure occurred.
