Next year, Environmental Services will replace old, deteriorating sewer pipes on the west side of the Grant Park neighborhood and along the boundaries of the Sullivan’s Gulch, Irvington, and Alameda neighborhoods. The tentative schedule is to start construction in spring 2014. The work will take about one year to complete.
The work is part of a citywide program to replace aging sewer pipes. Over one-third of Portland’s 2,500 miles of sewer pipes are more than 80 years old. Projects to replace or repair aging sewers are important for protecting water quality, public health, and the environment.
What’s Happening Now?
Environmental Services is inspecting pipe and designing the repair project. Survey crews have been accessing sewers through manholes and inspecting sewer pipes to determine which pipes need repair. You may also notice crews collecting soil samples in the street or marking utilities. More information on the type of construction technique used at each repair location will be available in the next few months after the assessment of existing pipes and construction issues is complete.
Check the project area map above to see if there will be construction on streets near your home next year. In the meantime, you can contact us to sign up to receive project updates by email.
Keeping You Informed
Environmental Services works to keep businesses and residents informed before and during construction. Watch your mail for project updates or contact us to be added to our email notices list. We will also reach out directly to businesses and neighbors who may have unique construction impacts.

The map above shows the location of pipes Environmental Services will repair or replace beginning in 2014. The work includes repairing some lateral pipes that connect private sewer lines to the public sewer. There will be construction only on the streets indicated on the map. There may be traffic control, construction signage or increased traffic volume on nearby streets. Watch your mail for updates as planning for construction continues.
Construction on NE Broadway
Environmental Services will replace the main sewer pipe under NE Broadway between NE 27th and NE 33rd avenues. The city’s contractor will likely dig a trench in NE Broadway to access the sewer and make the lateral connections to properties on both sides of the street. This will affect travel lanes, sidewalks, and some on-street parking. There will be access to business parking lots and driveways, but there will be some travel delays in the area during construction. Environmental Services is exploring ways to minimize the disruption for businesses and motorists.
Frequently Asked Questions
Although it is early in planning for the construction that begins next year, we receive many questions from neighbors. The following are answers to some of the most common questions.
What should we expect during construction?
For most sewer repair projects, the contractor excavates a trench in the street, replaces the sewer pipe, refills the trench and restores the pavement. The contractor can sometimes use trenchless construction methods, such as pipe lining, which are less disruptive. The contractor will likely be able to use trenchless repair methods on some of the segments shown on the map.
Engineers designing this project are exploring construction methods. When design is complete, we will update the project area map to show the construction methods selected and we will know more about how the project will affect the neighborhood. You will receive additional notification in advance of any work.
Will any streets be closed?
Construction may limit some streets to local access only or reduce traffic lanes. The contractor may need to reduce some streets to one lane with flaggers directing traffic. This will cause brief vehicle and pedestrian delays. There are no plans to completely close access to streets. The Portland Bureau of Transportation will review traffic control plans and will share the plans with the neighborhoods.
Will construction block my driveway?
Open trench construction may temporarily block some driveways, but probably no longer than a few hours. We will notify homeowners in advance of blocking any driveways and the contractor will not block cars from leaving driveways.
Will I lose sewer or water service during the project?
When construction crews temporarily disconnect lateral sewer lines, they maintain sewer service by using temporary pipes to move sewage around the disconnected lateral. If a short, temporary water service shut-off is necessary to relocate a line, the contractor will notify homeowners in advance.
When will work be completed?
The work will begin in spring 2014. When the city hires a contractor, we will release a more exact schedule. Construction time at each repair segment will vary.
It will take the contractor about one year to complete all the segments. Pavement restoration follows sewer construction and is weather-dependent. Construction hours are typically Monday through Friday from 7:00 a.m. until 6:00 p.m. Contractors may work the same hours on Saturday if needed.
I see sewer construction already in my neighborhood. Is that part of this project?
The NE Klickitat Neighborhood Greenway project is also under construction near you. Environmental Services began installing sewers on NE Klickitat Street in January 2013. The city's contractor completed sewer construction in March 2013 and began construction on 26 green street stormwater facilities on NE Klickitat, Morris and Siskiyou streets between N Vancouver Avenue and NE Sandy Boulevard.
