Northwest District Sewer Replacement Project

Night Work on NW Vaughn

March 1, 2017 

Sign up for email construction updatesEnvironmental Services is continuing construction of the Northwest District Sewer Repair Project to repair or replace about 8,000 linear feet of public sewer pipes that are 116 years old and in deteriorating condition. The project will increase sewer system capacity to relieve basement sewer backups and help protect public health, water quality and the environment.

Construction Schedule

Our contractor will finish up main line sewer installation on NW Upshur and then move to NW Vaughn to complete manhole installation on the final intersections remaining. Each intersection will take about a week to complete. The pipe installation on NW 23rd Avenue will take about a month to complete. The cured-in-place pie lining is not currently scheduled, but this will be performed at night, also.

The remaining pipe installation south of NW Vaughn on NW 23rd and 24th places, and on NW 23rd Place & NW York will be scheduled at a later time, you will be notified.

Final paving and restoration will be completed as the weather allows. Paving requires dry weather and a temperature above 40 degrees.

There will be periods of inactivity between phases.

Night work locations

Noise Variance

The Portland Noise Control Office granted Environmental Services a noise variance for overnight construction at specified locations (see map) for up to five months 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.
