St. Johns-Cathedral Park Sewer Repair

Button. Click to sign up for email updatesUpdated September 8, 2017

Environmental Services plans to begin construction in early 2018 on a project to repair or replace over 15,000 feet, or about 3 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.

Noise Review Board Public Hearing

Due to high traffic volume during the day, Environmental Services has requested a variance from the Portland Noise Office to allow overnight construction on several streets within the project area (see map). The Portland Noise Review Board requires a public hearing on the noise variance request. The public will have an opportunity to make comments and ask questions at a future hearing.

Night Construction Methods, Locations, and Estimated Durations

The contractor will use open trench excavation and/or pipe bursting during the proposed nighttime construction. That includes using an equipment truck, water jet truck, CCTV truck, vacuum truck, air compressor, asphalt truck, pavement saw cutters, whisper bypass pumps, generators, lights, dump trucks, front end loaders, track hoes, cranes and pavement roller compactor, lighting, metal sheets and power tools. Below are the locations and estimated durations of overnight open trench and/or pipe bursting construction.

  • N. Midway (between Fessenden and Powers) – open trench up to 3 nights
  • N Ida (at Kellogg) – open trench or pipe bursting up to 6 nights
  • N Ivanhoe (between John and Charleston) – open trench or pipe bursting up to two weeks
  • N Lombard (between John and Richmond) – open trench or pipe bursting up to three weeks

The contractor will repair pipes with cured in place pipe (CIPP) lining in three areas. CIPP work includes using whisper bypass pumps, generators, lights, dump trucks and front end loaders.

  • N Swift Way – prepare area and CIPP lining up to 3 nights
  • N Fessenden (between Midway & Columbia) – prepare area and CIPP lining up to 5 nights
  • N Lombard/US 30 Bypass (between Polk and Burr) – prepare area and CIPP lining up to 5 nights

When possible, work crews will complete louder tasks before midnight. This construction schedule is tentative and subject to change. Go to for more information about construction methods. 

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.
