The City of Portland’s Bureau of Environmental Services is continuing our work to repair and replace critical sewer and stormwater infrastructure. Environmental Services will continue to provide information and updates on construction schedules and activities during the COVID-19 emergency.
Updated May 18, 2020
Environmental Services – your sewer and stormwater utility – is designing a project to repair a section of large concrete sewer pipe along SE Stark Street between SE 3rd Avenue and the Willamette River. This section of pipe is part of a sewer known as the Stark Trunk. It was built in 1911 to manage sanitary sewage and stormwater from a large area of Northeast and Southeast Portland.
The trunk is now showing signs of deterioration and needs to be repaired. The sewer and stormwater improvements will extend the service life of the trunk by 50 years or more, increase sewer resiliency to earthquake damage, and help prevent sewage releases to buildings and streets
Construction is expected to start in late 2022 and should take about a year to complete.
While proposed pipe work is on SE Stark Avenue is between SE 3rd Avenue and the Willamette River, the project team will also be collecting information about underground utilities and soil conditions between SE 3rd and 12th avenues for future projects.
Beginning early June and continuing periodically over the summer, work crews will be drilling small holes in the pavement in order to take soil samples within the project area. Information gathered will help designers understand the underground conditions surrounding the proposed pipe work locations and help determine construction materials and methods. Crews will also be taking samples on SE Stark Street between 3rd and 12th avenues to collect soil information for future projects not yet in design.
Environmental Services will work directly with the community throughout the course of the project. Community outreach staff will listen to your suggestions and respond to your concerns. We encourage you to:
In the event of a sewer backup or basement flooding, call the Maintenance hotline immediately at 503-823-1700. It is staffed all hours and all days, 24/7.
