Eliot Sewer and Stormwater Project

Updated November 19, 2019Button. Click to sign up for email updates

Environmental Services has completed major construction on a sewer repair and stormwater management project in the southern part of the Eliot neighborhood. The project has upsized, repaired or replace approximately 10,000 feet of deteriorating public sewer pipes that are 100 to 120 years old.

We also constructed 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. 


Work will continue on miscellaneous items throughout the project area as crews are available:

  • This work includes manhole repair work, sidewalk corner ramp construction, stormwater inlet work, and removing equipment  and materials.

Green Streets

Vegetation was planted in green street planters in early November 2019.  Plants will take about two years to establish and will be receive regular care during this time period. 

After plants have established maintenance, will be performed seasonally. Maintenance includes removing sediment, leaves or trash that can impede water flow, replacing plants, and watering. 

The city welcomes volunteer Green Street Steward partnerships. To learn more go to

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.
