Eliot Sewer and Stormwater Project

Updated November 30, 2018Button. Click to sign up for email updates

Environmental Services continues construction on a sewer repair and stormwater management project in the southern part of the Eliot neighborhood. We will upsize, repair or replace approximately 10,000 feet of deteriorating public sewer pipes that are 100 to 120 years old.

We will also construct 8 green street planters on public streets to reduce the amount of stormwater entering the combined sewer system in key locations. The green street planters built as part of this project will divert 1.9 million gallons of stormwater annually from the sewer system. Separating stormwater from sewer pipes reduces the risk of street flooding, basement sewer backups into homes and businesses, and overflows into our rivers during periods of heavy rain.

These improvements will protect public health, property and the environment. 

Developments of Note

For the remainder of the project, when additional crews are available, work will occur on Saturdays and in additional locations.

  • This project is expected to be completed in summer 2019.

Sewer Construction Update

Please be aware that schedules are subject to change due to a variety of factors, such as conditions underground, weather, traffic impacts, and subcontractor and materials availability issues.

Open trench sewer construction will begin on NE Sacramento Street between Martin Luther King Jr. Boulevard and 7th Avenue next week and continue through December.

  • Construction activities will close the road to between 7:00 a.m. and 6:00 p.m. each day, but access to homes and business will be maintained. If crews are available, work will occur on Saturdays to complete work faster.
  • There will be no on-street parking in and near the work zone to create a safe work area and for storage of equipment and materials.
  • Each day, the contractor will patch trenches used during construction with temporary pavement to make the street useable during non-working hours. Permanent trench patching will be scheduled for a later date. 
  • Sewer, water, and other utilities are expected to stay in service during sewer construction.

Crews have completed installing new public sewer mainline pipe on NE Brazee Street between Martin Luther King Jr. Boulevard and 7th Avenue, but additional work remains.

  • Remaining work includes connecting the new mainline sewer to a manhole in Martin Luther King Jr. Boulevard, building new sewer connection from the mainline to the curb in front of each building, and installing green street planters to reduce the amount of stormwater entering the combined sewer system.
  • Permanent trench patching of areas of the roadway removed for construction.
  • Remaining work will be performed in phases. There will be periods of inactivity between each phase ranging from a few weeks to a few months in some cases.      

Sewer Progress

Traffic Impacts

Traffic control plans approved by the Portland Bureau of Transportation (PBOT) will be implemented to create a safe work zone. Traffic control plans will vary depending on the type of work occurring and will include lane, intersection and road closures. If needed, detours will be put in place. Neighbors should expect traffic delays in and near the work area. Please drive or bike with caution when passing through work zones. Observe traffic control signs and follow the direction of flaggers if present. To learn more about what to expect during construction go to

Biking and walking near construction: Did you know?

When the street or lane is closed for construction, pedestrians and cyclists can almost always use the sidewalk, but should do so with caution. Sidewalks near construction zones can become unusually congested and awareness of your surroundings can help avoid accidents. Please take extra time to walk or bike past work zones. In addition, cyclists must avoid riding on closed roadways even if it looks like there’s enough room for a bike to navigate around construction. When construction takes place on a street with a bike lane, crews will post signs to guide cyclists. For an interactive map of safe walking and biking routes in the City, visit:

Night Work

The Portland Noise Office has granted Environmental Services a noise variance to allow up to 52 nights of work outside of typical construction hours from 6:00 p.m. to 6:00 a.m. at six locations. (see project map) There will be lights at each construction area and noise from construction equipment, vehicle and generators. Crews will use “smart alarm” backup beepers after 10:00 p.m. and all necessary saw cutting will end at midnight.

Working at night will speed the construction process as well as minimize traffic disruptions for heavily traveled roads. On average, 5 - 10 night shifts will be needed to complete work at each of the six intersections. Nights shifts may not be consecutive.
