Eliot Sewer and Stormwater Project

Updated July 12, 2019Button. 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. 

General Schedule

Construction is expected to be complete in late July or early August 2019. For the remainder of the project, when additional crews are available, work may occur on Saturdays throughout the project area.

Look-ahead Schedule

Please scroll down to view maps showing locations for sewer construction, street restoration, and detour routes. 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.

Paving on North Vancouver Avenue (Hancock to Russell) will detour traffic in route to Broadway Street next Monday, July 12, 2019:

  • Please scroll down for more information and to view a map of the detour. 

Sewer construction will continue work on Flint Avenue between Tillamook and Page streets through next week:

  • One lane next to the work zone will be maintained with flaggers controlling two-way traffic.
  • People traveling on Flint Avenue between Tillamook and Page streets should expect delays.

Green street planter construction in the project area is nearly complete:

  • Crews are adding soil and protective matting to each planter.
  • Vegetation will not be planted until the fall or winter 2019 and will take time to establish. To learn more about green street planters and construction steps go to

Sewer Progress

Paving on North Vancouver Avenue (Hancock to Russell) will detour traffic in route to Broadway Street Monday, July 15, 2019.

  • The detour will be in place from 9:00 a.m. to 6:00 p.m.
  • Cars and trucks traveling south on Vancouver will be detoured to MLK Jr. Boulevard at Russell Street. Bikes will be detoured to Rodney Avenue.
  • Access will be maintained for those living and doing business on Vancouver between Hancock and Russell.
  • Businesses are open during construction and we encourage you to support them.

Detour Map

We know that sewer construction disrupts normal daily routines and causes traffic delays. We ask that the traveling public please be patient, travel with extra caution, and watch for families and children walking and biking to Harriet Tubman Middle School and Lilis-Albina Park on Flint and connecting side streets.

Environmental Services is coordinating with the Portland Bureau of Transportation (PBOT), Harriet Tubman Middle School and Portland Police Traffic Division to maintain safe traffic flow in the neighborhood. You can help us maintain safety near the Harriet Tubman School Zone and Lilis-Albina Park by using designated detour routes when traveling south from Russell to Broadway.

Thank your for your cooperation and patience during this important phase of construction.


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

Night work related to this project was completed in May 2019. 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). Working at night reduced the amount of time needed to complete construction and minimized traffic disruptions on this heavily traveled road. On average, 5 - 10 night shifts were needed to complete work at each of the six intersections.
