St. Johns-Cathedral Park Sewer Repair

Button. Click to sign up for email updatesUpdated July 22, 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 July 22: 

Paving will take place at the following locations weather permitting:

  • N Ivanhoe Street between John Avenue and Charleston Avenue. This will take up to three nights to complete. (Night work)
  • N Fessenden Street west of Columbia Way. This will take one day to complete.
  • N Kellogg Street between Burr Avenue and Ida Avenue. This will take one day to complete.

 

Week of July 29:  

N Lombard Street between Polk Avenue and Burr Avenue

  • Crews will repair a few lateral pipes and construct several new clean outs. This will take about two days to complete.

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

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 www.portlandoregon.gov/bes/constructionimpacts.

People who live and work near a CIPP repair project can sometimes smell a chemical odor during the lateral pipe-lining work. The odor is from the chemical styrene, which is in the resin liner installed inside the pipe. The odor dissipates quickly once the installation is complete. The amount of airborne styrene produced by the lining process is not expected to cause health issues for workers or the public. 

Water Use During CIPP Construction

Your water service should not be interrupted during the repair work; however, we request that you minimize your water usage because drainage into the sewer will be restricted and a back-up could occur in your home/business. Please do not run your dishwasher or washing machine and limit showers/baths until after the work is complete. 

Typical work hours are 7:00 a.m. to 6:00 p.m. Monday through Friday, but the contractor may schedule work during the same hours on Saturdays.

Residents and businesses should expect periods of inactivity between phases of work, ranging from a few days to a few weeks. In areas where the repair requires a trench, temporary pavement will be applied to the site until permanent pavement can be applied later. The duration of any period of inactivity depends on a variety of variables including underground conditions, weather, traffic impacts, subcontractor schedules, quality control tests, and availability of materials. In the event of a sewer backup, storm drainage problems or clogged catch basins, call 503-823-1700.

Work Hours

Typical work hours are 7:00 a.m. to 6:00 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 as early as 5 a.m. on Lombard Street between John Avenue and Lombard Way.

Residents and businesses should expect periods of inactivity between phases of work, ranging from a few days to a few weeks. In areas where the repair requires a trench, temporary pavement will be applied to the site until permanent pavement can be applied later. The duration of any period of inactivity depends on a variety of variables including underground conditions, weather, traffic impacts, subcontractor schedules, quality control tests, and availability of materials.
