NW 9th and Hoyt Sewer and Water Pipe Improvement Project

Sewer and Stormwater
Active
Environmental Services, in partnership with the Portland Water Bureau, is constructing a project to upgrade infrastructure in NW Portland. This project will increase system capacity, reduce the risk of sewer discharges, and improve earthquake resilience for our critical infrastructure.
Design has been completed. Construction began in June of 2024 and should take about six months to complete.

Project Area

This project is in the Pearl District Neighborhood at the west end of the Broadway Bridge adjacent to the former US Post Office site.

Project Schedule 

Construction will begin during the week of June 10th.  Major construction activities should take two-four weeks on each block. Pavement restoration will occur once construction is complete. It is expected that the overall project will take approximately six months. Work will occur in phases, and not all at once. There may be periods of inactivity between construction phases due to a variety of factors including weather, subcontractor schedules, and availability of materials.

Construction hours for this project are expected to be 7 a.m. to 6 p.m. Monday through Friday, with some work possible on Saturdays if needed.

What To Expect During Construction

Construction creates noise, vibration, and dust and can disrupt normal neighborhood activity. We want you to be safe around the work site. Please keep children, pets, bikes, cars, and trucks away from the tools, machines, supplies, and construction workers. A city inspector will be on-site during work hours and may be able to assist you with construction concerns. Inspectors typically wear a hard hat and safety vest with “City of Portland” on the back. 

To learn more about what to expect during construction, please review the brief guide on what community can expect during ongoing projects conducted by Environmental Services.

PBOT Johnson & Kearney Street Extension Project

As part of the larger Post Office Blocks redevelopment effort, our partners at the Portland Bureau of Transportation (PBOT) will construct new streets through the former United States Postal Service site. PBOT will build new sidewalks, streets, separated bike lanes, as well as intersections through the redevelopment site to connect to the existing street network. The project focuses on extending NW Kearney and NW Johnson Streets through the site from NW 9th Ave to NW Station Way.

Construction for this related project is expected to begin in late 2024. 

Please visit the Johnson Kearney Extension Webpage to learn more.
