Approval of the 170th Ave NE Road Closure for Penny Lane Development Sewer Line Work
OVERVIEW STATEMENT:
recommendation
Penny Lane is Private Development townhome construction project adjacent to 170th Ave NE. As part of the project, improvements in the roadway include an update to the sewer line on 170th Ave NE. The sewer line is situated in the middle of the roadway and requires deep excavation. The Contractor was given approval by City Council to close the roadway in lieu of using steel trench plates.
We are currently seeking an extension of the previously approved road closure for the Penny Lane project as the work is taking longer than originally planned. The approved road closure expires Friday, June 11th. The sandy soils are creating sluff, which is slowing the current process, the contractor has an additional 200 feet of sewer line to install and are expecting construction to take an additional 20-25 days to complete.
Construction activity would take place between 7AM-7PM Monday through Friday with potential of Saturday work. Approval for full road closures is required from Council per RMC 10.24.047.

Time Constraints:
The deep excavation for the sewer line requires it to be done during dry summer months. Contractor has also started the sewer work with limited work hours per day with the sewer bypassed via a temporary pipe. It will be important to complete the sewer connection and disconnect temporary bypass lines to reduce risk of sewer leaks.
ANTICIPATED RESULT IF NOT APPROVED:
Increased working days for work completion would result in additional disruption to residents and require use of the temporary sewer line for longer duration. A full road closure also ensures vehicular traffic is prohibited in the work zone, reducing noise and risk to the Public.
