St. Johns-Cathedral Park Sewer Repair

Button. Click to sign up for email updatesUpdated April 25, 2019

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.

St Johns-Cathedral Park Construction Map

Construction Schedule:

Construction began mid-September 2018 and will take about a year to complete. Depending on the location and construction method, work could last up to a month or more in one area.     

Week of April 29:  

N Midway Avenue between N Fessenden Street and N Powers Street

  • Crews will continue to repair a couple of lateral pipes using open trench construction. This will take about two more days to complete. 

Permanent concrete paving will occur at the following location, weather permitting:

  • N Leonard Street between N Buchanan Avenue and N Burr Avenue 

Permanent asphalt paving will occur at the following locations, weather permitting:

  • N Kellogg Street between N Tyler Avenue and N Polk Avenue
  • N Jersey Street between N Tyler Avenue and N Polk Avenue
  • N Ivanhoe Street west of N Polk Avenue


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

What to Expect during Construction

We have started some pre-construction activities and you may see crews working in your neighborhood. Activities could include documenting pipe conditions via video cameras; fencing off trees for protection; tree trimming; installing manhole steps; equipment use and storage; noise, vibration and dust; traffic delays, and parking restrictions. To learn more about what to expect during construction go to

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.
