Environmental Services will soon begin construction on a project to repair 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 investment in your neighborhood will allow for continued dependable sewer service and protect the public and our environment by reducing the possibility of sewage releases to homes, businesses and streets.
Construction is beginning 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. For the most up-to-date information and map of the project schedule, visit www.portlandoregon.gov/bes/StJohnsCPark.
Construction activities will occur between September 24th – October 4th in the following areas:
N Mohawk Avenue between Bank Street and Olympia Street – Crews will install manhole steps as well as make four spot repairs on the sewer line, which will each require digging a small trench. This work will take up to a week to complete.
N Hartman Street near Pier Park Place – Crews will install manhole steps and repair the sewer line using open trench excavation. This work will take up to a week to complete.
N Mohawk Avenue between Fessenden Street and Olympia Street – Crews will install manhole steps and repair a section of the sewer line using open trench excavation. They plan to return in the spring to repair the other section using cured-in-place pipe lining.
Crews may be installing manhole steps in the following work areas between September 24th - October 4th. It usually takes one day to complete each area.
N Chicago Avenue between Smith Street and Seneca Street
N John Avenue between Hudson Street and Smith Street
N Trumbull Avenue between Hudson Street and Smith Street
N Hudson Street between Trumbull Avenue and St Louis Avenue
N St Louis Avenue between Hudson Street and Smith Street
N Central Street between Bristol Avenue and Trumbull Avenue
N Central Street between Trumbull Avenue and St Louis Avenue
N Columbia Boulevard between Midway Avenue and Oregonian Avenue
The city uses many construction methods to repair or replace sewer pipes. For the upcoming sewer line repairs, the city plans to use Open Trench Excavation. To learn more about different 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; equipment use and storage; noise, vibration and dust; traffic delays, and parking restrictions.
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 at a later date. 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.
