NW Thurman Sewer Reconstruction

Updated June 29, 2018Button. Click to sign up for email updates

Environmental Services is designing a project in NW Thurman Street to reconstruct more than 3,000 feet of public sewer pipes. The project will also construct new manholes, storm drains, and service laterals that connect private properties to the public sewer. These improvements will increase the capacity of the 100-year-old infrastructure to accommodate future growth in the area and relieve basement sewer backups at 31 properties.


Project design will continue into the spring of 2019. Construction is anticipated to begin in the summer of 2019 and take about a year to complete.

Additional survey work will occur throughout the project area this summer.


Neighbors will see Survey crews at the following locations:

  • NW 31st Avenue between Thurman and Vaughn streets
  • NW Vaughn Street between 31st and 30th avenues
  • Intersections throughout the project area

Survey Work

Additional survey work is necessary to help engineers determine what pipes need to be repaired or replaced and what construction methods to use for each pipe. Survey activities will include the following:

  • Locate and mark underground utilities
  • Measure elevations and slopes
  • Collect details about manholes
  • Identify, tag, collect data, and determine protection zones for trees
  • Collect first floor elevation information for several properties

What to Expect during Survey Work

Survey crews will move throughout the project area, marking locations of right-of-way boundaries, utility vaults, and other landmarks. See the graphic to learn what the various color markings mean.

Survey crews may also work on the sidewalks and streets in front of your property to measure the elevation of your first floor and see if the house has a basement. Occasionally, crews may contact individual property owners if they need to access their properties.

Sometimes crews use large trucks to dig holes in the right-of-way or street to locate utilities that may be close to or in the way of a sewer/stormwater pipe or other structure. Crews fill the holes immediately afterwards and apply temporary pavement if needed. Streets are typically permanently paved at the end of construction.

This work may have temporary traffic impacts, including restricted lanes, on-street parking removal, and delayed access to and from driveways. This work may also cause brief periods of noise, dust, and mild vibration.

Report Basement Backups

If your basement sewer backs up or your property or street floods, please report it immediately to the city’s 24/7 Maintenance Operations hotline at 503-823-1700. They will log the issue in a tracking database, visit the location to investigate the issue, make an emergency repairs where necessary, and use this information to help plan future improvements to the system. This information will also be used to improve the local surface drainage conditions where possible. Please report an issue as it is happening so responding crews can observe it. We also encourage you to call the hotline to report locations where there is a history of local surface drainage issues.
