SW Kingston Avenue Stormwater Improvements

Sewer and Stormwater
Active
Environmental Services has installed two underground stormwater management facilities on SW Kingston Avenue. The stormwater improvements will reduce the risks of sewage releases to homes, businesses, and streets.
Construction is complete and final paving is happening the week of April 8.

Nearby properties had reported sewer backups in the past and there is ongoing high risk of basement sewer backups. This is a result of too much groundwater in the area.

What’s Happening Now

All work is weather-dependent and subject to change.

Week of April 8:

Crews will final pave Monday through Wednesday.

Street Closure

SW Kingston Avenue from the Japanese Gardens to SW Fairview Blvd will be closed to through traffic (local access to residents only), Monday through Wednesday, 24 hours a day. The construction activities will take place from 7:00 a.m. to 5:00 p.m. on these days. Closing the street to through traffic during the week will expedite the project and reduce the schedule by several weeks.

Crews will work with residents to get people in and out of their homes in the project area. The sidewalks will remain open for pedestrians and bicyclists.

What to Expect During Construction

A brief guide on what you can expect during construction projects conducted by Environmental Services and their contractors can be found at portland.gov/bes/constructionimpacts.

Underground Stormwater Management

Underground stormwater management structures are specially designed to filter stormwater, reduce the amount of pollution entering city pipes and reaching the Willamette River, and reducing the volume of stormwater entering the piped system.

This project is proposing to install a Sedimentation Maintenance Hole and a Manufactured Stormwater Treatment (MST) with a pipe connection as an underground stormwater management system.
