Eliot Sewer and Stormwater Project

Updated August 13, 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

Environmental Services expects to complete major construction efforts the week of August 19, 2019. Additional miscellaneous outstanding items such as manhole repair work, sidewalk corner ramp construction, cleaning, and demobilizing from the project area will extend into September 2019.

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.

Businesses Open During ConstrucitonStreet restoration (paving) will close Flint Avenue between Page and Tillamook streets Monday, August 19, and Tuesday, August 20:

  • Local access will be maintained, but no traffic will be allowed through the intersection of Tillamook and Flint from 7:00 a.m. to 6:00 p.m. People living or conducting business near the work zone should expect significant delays.
  • People traveling southbound on Flint Avenue from Russell Street will be detoured at Page Street to Vancouver Avenue.      
  • People typically traveling north on Flint Avenue from Broadway should use Williams Avenue from Broadway as an alternative northbound route. 

Crews will be completing miscellaneous outstanding items throughout the project area through August and into September.

  • Miscellaneous outstanding include manhole repair, installing sidewalk corner ramps, cleaning, and removing equipment and materials.

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

  • Painting the street-side curb of each planter, adding reflective markers, and planting vegetation remain. 
  • 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

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.
