Parkrose Stormwater Project

Updated October 1, 2020Sign Up for emails

The City of Portland’s Bureau of Environmental Services is continuing our work to repair and replace critical sewer and stormwater infrastructure. Environmental Services will continue to provide information and updates on construction schedules and activities during the COVID-19 emergency.


Environmental Services is completing construction of a stormwater management
project in a portion of the Parkrose neighborhood. This project is part of a
larger effort to improve water quality in the Columbia Slough. This project constructed
10 underground injection control structures, 12 manholes with manufactured
stormwater treatment systems, 22 sedimentation manholes, and two green streets.
These new structures will improve water quality, help control stormwater runoff
during heavy rain events, and protect the Columbia Slough.


Map of the Parkrose Stormwater Project

The construction boundary is NE Marx Street to NE Shaver Street between NE 116th Avenue and NE 122nd Avenue.

Look-ahead Schedule

General construction hours will be from 7 a.m. to 6 p.m., Monday through Friday, with some Saturday construction as needed. 

Crews will continue final pavement restoration on streets where crews had to dig into the street to repair public sewer pipes and now have temporary asphalt patches between October 1 and October 16. The contractor is completing final pavement restoration as weather permits. Final pavement restoration is scheduled at:

  • Various locations on NE 122nd Avenue, between NE Shaver and NE Marx streets
  • NE Prescott Street, between NE 116th and NE 118th avenues
  • NE 121st Place, between NE Skidmore and NE Prescott streets

Due to the nature of this project, our contractor will be moving rapidly to different parts of the locations mentioned above. The stormwater management improvements will have several phases, including some phases of inactivity, and should be completed by spring 2021.

Access During Construction

Environmental Services and our contractor, Landis & Landis Construction, understands the importance of having access to food resources, such as the one at Parkrose Middle School, during this unprecedented time. We are communicating and coordinating with the school around informing parents of alternative ways to enter the school while temporary closures on NE Shaver Street occur during construction.

Frequently Asked Questions

What is a Green Street?

Green streets are rain gardens that collect stormwater runoff from streets and allow water to soak into the ground as soil and vegetation filter pollutants.

What will they do?

Currently when it rains, water flows from streets and sidewalks into the storm system that carries it directly to the Columbia Slough. The new green streets will collect and filter this polluted runoff before it enters the pipes or soaks into the ground to protect water quality in the Columbia Slough.

Who maintains these new rain gardens?

The city maintains green streets to ensure that they effectively manage stormwater. Portland has more than a thousand green streets across the city.

Where will the green streets be located?

Environmental Services locates green street planters where they will be most effective in collecting stormwater. The planters in this project will be curb extensions, extending into the on-street parking zone next to the curb.

Will there be a green street outside of your house?

Environmental Services will communicate with all adjacent property owners where proposed green streets will remove on-street parking spaces.
