St. Johns-Cathedral Park Sewer Repair

Button. Click to sign up for email updatesUpdated October 18, 2018

Environmental Services is constructing a project to repair or replace over 11,000 feet, or about 2 miles, of public sewers in the St. Johns and Cathedral Park neighborhoods. Many of the sewer pipes are about 80 years old and deteriorating due to age. This project will protect the public and the environment by reducing the possibility of sewage releases to homes, businesses and streets.

Construction Schedule: 

Week of October 22:

  • Crews will continue the lateral pipe work on N Chicago Avenue between Smith and Seneca streets. This work will take a couple more days to complete.

Business Coordination

As project design continues, we will be visiting businesses nearest to the repair areas to discuss their needs during construction (e.g., delivery and access). If you would like to complete a business questionnaire in advance, click here. If you would like to talk with us, please contact us to schedule a visit.

Construction Methods

The city uses many construction methods to repair or replace sewer pipes. In your area, the city plans to use Cured-in-Place Pipe Lining (CIPP), Open Trench Excavation, and Pipe Bursting.  To learn more about each of these constructions methods and what can be expected during construction, go to www.portlandoregon.gov/bes/methods.

What to Expect during Construction

Beginning mid-August, you may see crews working in your neighborhood. Activities could include documenting pipe conditions via video cameras; equipment use and storage; noise, vibration and dust; traffic delays, and parking restrictions. To learn more about what to expect during construction go to www.portlandoregon.gov/bes/constructionimpacts.

Work Hours

Regular work hours will be 7 a.m. to 6 p.m. Monday through Friday, and Saturdays as needed. The Portland Noise Office granted Environmental Services a Noise Variance to enable the city’s contractors to work at night to complete work at the locations proposed on the map (see other side). Night work reduces traffic congestion, creates a safer work zone, and in some locations, will allow sufficient time for a new sewer pipe lining to harden.
