Lower Powell Green Street and Sewer Project

Updated June 16, 2017

Work is near completion on an Environmental Services project to replace and repair 4,500 feet of sewer pipe that is over 100 years old and in poor condition, construct 22 green street facilities and plant 11 trees to absorb rain and reduce stormwater runoff. The project will keep about 1.6 million gallons of stormwater out of sewers annually, increase sewer system capacity and reduce the risk of basement backups. This project is part of the Tabor to the River Program, which combines green infrastructure with pipe repair to save Portland sewer ratepayers more than $60 million dollars.

Remaining work is expected to be completed by the end of June 2017

  • Remaining work includes overnight construction to repair deteriorating public sewer pipe underneath the SE McLoughlin Boulevard - Powell Boulevard off ramp. This work will close the ramp at night between 9:00 p.m. and 5:00 a.m. for up to seven nights between June 14 and June 30 and will include a detour.
