Downtown-Old Town Sewer Repairs

Updated June 5, 2017

Environmental Services has completed this phase of a project to repair 100- to 140-year-old public sewer pipes in SW Yamhill and SW Morrison Streets in downtown Portland that were in deteriorating condition. The repairs will protect the public and the environment by reducing the possibility of sewage releases to buildings and streets.

The SW Yamhill-Morrison Sewer Repair Project was in construction from March 15 to May 20, with the most challenging work accomplishted in May when TriMet closed the MAX line for repair, giving city crews a window to safely access sewer pipes under the tracks. For information about what the project accomplished and the work that remains to be done, click here.

Get Portland MovingDowntown Open for Business

Throughout 2017 and into 2018, the Central Business District will be the site of multiple projects to repair and replace aging sewers, rail lines, bridge structures, streets, and other infrastructure. Projects with long-term benefits will cause short-term disruptions to residents, businesses, and visitors. Environmental Services is coordinating with multiple agencies to schedule and complete construction, minimize disruptions, and help people get to where they are going. For more information, visit

To avoid circling around construction to find parking, the City recommends you use SmartPark garages.
