Nearby properties have 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.
The map illustrates the project area, which is on SW Kingston Avenue, north of the Japanese Garden and south of SW Fairview Blvd.
What’s Happening Now
Preconstruction Activities: February 15 through February 21
Prior to construction, crews will begin preparing for construction by trimming trees, installing tree protection measures, erosion control, and traffic control devices. The tree work will be coordinated closely with City of Portland’s Urban Forestry. For more information on these pre-construction activities, visit portland.gov/bes/pre-construction.
Construction Begins: February 22
Due to extreme weather in January and other emergency projects, construction has been delayed by a couple of weeks.
Starting the week of February 19, crews will begin locating existing utilities, installing the 60-inch maintenance hole and 46 feet of 12-inch stormwater pipe.
SW Kingston Avenue from the Japanese Gardens to SW Fairview Blvd will be closed to through traffic (local access to residents only), Monday through Fridays 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. SW Kingston will be opened back up on weekends to accommodate visitors at the Japanese Gardens and Washington Park Rose Gardens. Washington Park is open to the public seven days a week, and the Japanese Gardens are open to the public Wednesdays through Mondays (closed Tuesdays).
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.
