This summer, Environmental Services will install a valve and underground vault at the intersection of SE 7th Avenue and Yamhill Street. The equipment will reduce the rare build-up of air pressure in the public sewer system that can occur during intense rainstorms. The project will help to ensure the sewer system operates safely and efficiently.
The project is located near the busy intersection of SE 7th and Yamhill. Construction is anticipated to begin as early as July 10 and take up to three weeks to complete. 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.
