Public sewer pipes in these neighborhoods were originally installed in the mid-1800s after Portland was founded in 1845. Having provided 100 to 150 years of service, the pipes are showing signs of cracks, breaks, holes, offset connections, and root and grease obstructions. If these pipes were to collapse, causing basement flooding and sewage releases to buildings and streets, the consequences would be catastrophic for downtown neighborhoods, whose businesses are so important to our local and regional economy.
The program also addresses nonconforming sewer connections and, where possible, provides properties an individual and direct connection to the public sewer system.
Environmental Services currently has several projects in various phases of planning, design, and construction to repair deteriorating 100 to 150-year-old public sewer pipes. The goals of these projects are to assess the condition of the public sewer system, identify and evaluate defects, prioritize the repairs and upgrades needed, identify the appropriate repair methods, and construct the repairs and upgrades.
The sewer system repairs and upgrades will be designed and constructed by Environmental Services and its contractors and will be supervised by its engineers, inspectors, and safety officers. Community outreach professionals will work directly with the community throughout the course of the projects.
The following Downtown-Old Town sewer repair projects have been completed:
- SW Caruthers-Mill Sewer Project (completed May 2020)
- SW Yamhill-Morrison Sewer Project Phase Three (completed November 2019)
- SW Yamhill-Morrison Sewer Project Phase Two (completed November 2018)
- SW Alder-Oak-Taylor Sewer Project (completed August 2018)
- SW Yamhill-Morrison Sewer Project Phase One (completed May 2017)
In addition, Environmental Services has completed several small emergency sewer repairs and provides ongoing sewer maintenance activities and repairs throughout the Downtown-Old Town area.
Downtown Open for Business
The Central Business District is 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 coordinates with multiple agencies to schedule and complete construction, minimize disruptions, and help people get to where they are going. For information about other projects that will affect travel in and around the Central Business District, visit www.MovePDX.net.
To avoid circling around construction to find parking, please use SmartPark garages.
Environmental Services is committed to ensuring the community is informed and engaged prior to and during the work associated with each of its Downtown-Old Town sewer repair projects. Community outreach staff will use a variety of communication tools to provide timely notifications about project design and construction activities and potential impacts.
Outreach methods will include the following:
- Direct mail.
- Hand-delivered fliers to downtown properties.
- On-site, in-person property visits and conversations.
- Regular email notifications.
- Social media posts.
- Project webpage updates.
