What to Expect During Construction
You may see crews working in your neighborhood to prepare for and perform sewer construction. Common activities include inspecting and cleaning sewers, marking the location of utilities, moving equipment and materials to the area, tree trimming, vegetation removal, setting up traffic control, and pipe repair or replacement. Expect traffic delays and parking restrictions near active construction zones. Visit the Construction Impacts webpage to learn more about what to expect during construction.
Private Belongings in the Right-of-Way
To construct the sewer extensions, crews will need to access and work in the public right-of-way — specifically between the curb and the edge of the sidewalk up to your property line. Anything belonging to you that is located in the right-of-way may be disturbed by construction, including irrigation systems, hard landscaping (stone, brick, pavers, garden boxes, retaining walls, or other construction materials), soft landscaping (trees, plants, shrubs, flowers, grass, bark, etc.), and other amenities. Please remove any items you wish to keep before crews get there. If the contractor finds items in the right-of-way that conflict with construction, crews will remove and dispose of the items.
If construction disturbs these kinds of items, the city cannot restore or replace them. However, once construction is complete, they will repair or replace sidewalks, driveway aprons, and curbs as needed. The city will also replace topsoil and grass seed in the planting strip, and any street trees that were removed.
We Want to Hear from You
We would like to hear from you about special events, school activities, and community services in the neighborhood that you think may be impacted by this project. Also, we want to know if you have any concerns related to business operations, disability or mobility issues, medical or business deliveries, and proposed night work. Your input will help us minimize construction impacts to your neighborhood.
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.
Environmental Services will use both trenchless and open trench excavation methods for this project. Construction methods are noted on the project map. Some will require digging trenches. Others will replace pipes through manholes or access pits to reduce disruption to the neighborhood.
Open Trench: The contractor excavates a trench, installs a new pipe, fills in the trench, and restores the disturbed pavement.
Cured-in-Place-Pipe (CIPP) Lining: Through a manhole, the contractor inserts a flexible liner into the old pipe. The liner hardens, creating a new interior lining.
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.
Jack and Bore: The contractor will drill a hole horizontally underground to install a new pipe where one was not one before.
Typical construction hours will be 7 a.m. to 6 p.m. Monday through Friday, and Saturday as needed. The project map indicates multiple locations where the project will require some night work. Due to the length and diameter of a few pipes, and for traffic safety reasons, some of the work will extend a few hours beyond 6 p.m. or will need to be done overnight. The Portland Noise Office has granted a variance to allow work to extend beyond typical construction hours.
S Corbett & Fulton Park Sewer Project
Environmental Services will replace the sewer pipes at the intersection of S Corbett Ave and S Fulton Park Blvd. Construction will begin in late Summer, 2022 and will be finished by late Fall, 2022. We are repairing these sections alongside a Portland Water Bureau project to minimize disruption to residents.
Environmental Services will be using the Open Trench Construction Method to install the new pipes. We will also be adding two new manholes, and two new storm drains (see map).
The Portland Water Bureau will replace an aging water main, connect that water main to nine water meters, add a fire hydrant, and repair the street. For more information about the Water Bureau work, visit the project webpage or contact the Water Bureau’s outreach representative Katy Asher at Katy.Asher@portlandoregon.gov.
The project scheduled for your neighborhood is part of the city’s program to maintain and upgrade the public sewer system. In the early 1900s, when Portland was growing rapidly, the city built hundreds of miles of sewers. Since most sewer pipes have a lifespan of about 100 years, Portland is now facing an urgent need to modernize its aging system.
Environmental Services has launched a large-scale effort to repair or replace the highest priority pipes throughout the city. Your neighborhood will experience a temporary disruption but will benefit from the improved infrastructure.
The city is replacing aging and deteriorating sewer pipes with modern materials. These materials are more resistant to blockages than the materials used 80 to 100 years ago. The updates will provide a safe, efficient, and reliable sewer system for your neighborhood and the city.
