1120 SW 5th Avenue, Room 1000, Portland, OR 97204
This fall, Environmental Services will install a valve and underground vault on NW 11th Avenue between NW Northrup and NW Overton Streets to reduce the rare build-up of air pressure in the public sewer system that can occur during intense rainstorms. The valve will help to ensure the sewer system operates safely and efficiently.
The project is located near the busy intersection of NW 11th and Northrup. Construction is anticipated to take up to four weeks and occur between October and December 2016. This includes time to set up, install piping and structures, and then restore pavement disturbed during construction.
Crews will work at the manhole in the street and install piping that connects to a new underground pressure valve and vault structure. There will be temporary traffic restrictions, such as reduced lanes or assistance from flaggers. Parking will be temporarily removed around the work area during construction. Environmental Services is designing the project now. More detailed information will be available this summer.
In the coming weeks, we will visit businesses nearest to the project area to discuss their needs during construction (e.g., delivery and access). At the time of the visit, we will provide a questionnaire that helps us know more about business operations and activities in the area as we prepare for construction. If we haven’t dropped by your location this spring and you’d like to talk with us, please contact us to schedule a visit.
If you have questions, comments or concerns about business operations, disability issues or medical or business deliveries, please contact Cheryl Kuck by phone at 503-823-7898 or by email. In your email and voicemail messages, please provide your property address and the project name (Upshur Shaft).
To sign up for periodic email updates, email Cheryl with “Upshur Shaft” in the subject line. If you provide your address, we can provide you with specific construction information about your location.
Thank you for your cooperation during this important sewer project.
