Eliot Sewer and Stormwater Project

Updated October 17, 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. 


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.  

Over the next two weeks, crews will continue to work on miscellaneous items throughout the project area:

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

 Spot paving is scheduled for the week of November 4 at the following intersections: 

  • Williams Avenue at Tillamook Street
  • Williams Avenue at San Rafael Street
  • Brazee Street at 7th Avenue
  • Sacramento Street at Martin Luther King Boulevard

Vegetation will be planted in green street planters between late October and late November.

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.
