Northwest District Sewer Replacement Project

Night work scheduled

Construction Schedule

Our contractor has scheduled the first manhole on NW 27th Avenue and NW Vaughn Street to be installed on Monday, October 17th. The manhole, storm drains and connections will be completed prior to moving to the next intersection and block. This work will continue one block at a time until the connection to the manhole located in the intersection of NW 23rd has been completed.

The estimated construction schedule is subject to change due to a variety of factors, including conditions underground, weather, traffic impacts, subcontractor schedules and availability of materials. The entire project is estimated to take about 18 months to complete.

Construction Methods

Construction will include both open trench and cured in place pipe lining (CIPP). The contractor will dig trenches to the curb to install laterals that connect individual properties to the sewer. There will be no loss of service to any properties during construction. There may be periods of inactivity.

Noise Variance

There will be up to 5 months of night work throughout this 18 month project timeline. We will continue to keep you updated as the project progresses.

The Portland Noise Office granted Environmental Services a noise variance for up to five months for overnight construction at specified locations on this project. Night work hours are 8:00 p.m. to 5:30 a.m. Sunday through Thursday. If you have questions or concerns during night work hours, you can call the City of Portland on-site hotline at 503-823-6290. You can also contact the Portland Noise Control Office by phone at 503-823-7350 or by email. If you have questions or concerns about the project during regular business hours, please contact Joe Annett by phone at 503-823-2934 or by email.  Environmental Services will also forward any noise-related comments to the Noise Office.
