Construction to Begin - Night Work

Current Construction Area

Construction Schedule

Our contractor is continuing pipe installation on NW Wilson, currently between NW 26th and 27th avenues. The work will then move onto NW 27th Avenue and head south to NW Vaughn.

There will be periods of inactivity between construction phases.

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.
