Project Area

What's Happening Now

Prior to construction, you may see crews surveying property lines, locating underground utilities, and trimming trees and shrubs in the work site. These activities help prepare the site for construction and will require minor traffic control to complete. 

This project will impact the planting strip between the curb and sidewalk and any areas immediately next to the work zone.  The planting strip and area immediately next to the road are considered the public right-of-way. If there are personal items that you have located in the public right-of-way in the project area, such as pavers or raised bed planter, please move them before construction begins. Please contact us for more information about the need to remove items you have in the right-of-way.

Sewer Emergency

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. 

Fats, Oils, and Grease – Did You Know?

Fats, oils, and grease (FOG) can build up overtime and completely block sewer pipes. Blocked sewer pipes can cause raw sewage to back up into homes or businesses, or overflow into streets and streams. For more information about FOG, visit: www.portlandoregon.gov/bes/FOG.

Construction Methods

Environmental Services will us a combination of open trench and pipe bursting construction methods to make the repairs.

  • Open Trench Pipe Repair: The contractor digs a trench, installs a new pipe, fills in the trench, and restores the patched trench with new pavement.
  • Pipe Bursting: The contractor pushes a bursting head into the sewer line to break apart the existing pipe while pulling a new pipe into place behind it.

For more details and photos of construction methods visit: www.portland.gov/bes/methods.

Public Sewer Easements and Private Property Access

Crews may need to access private property for survey, other information-gathering activities, and eventual possible sewer repairs. City outreach staff will coordinate with affected property owners for access to public sewer pipes and manholes.

About Stephens Creek

Stephens Creek begins at a steep ridge south of the Hillsdale Neighborhood center and flows about two miles to the Willamette River just north of the Sellwood Bridge. The creek drains a 754-acre watershed of mostly residential and commercial development around Burlingame, part of the Interstate 5 corridor, and the SW Taylors Ferry Road canyon.

The Stephens Creek watershed is one of 27 subwatersheds in the lower Willamette River. It is one of the few remaining streams in Portland that flows mainly above ground from its headwaters to the Willamette River. The mouth of Stephens Creek provides important off-channel habitat for fish in the Willamette River.
