Lower Powell Green Street and Sewer Project

Updated February 13, 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 complete by the end of February 2017

  • Remaining construction includes repairing public sewer pipe underneath the SE McLoughlin/Powell Boulevard off-ramp, spot paving in multiple locations, and stormwater inlet pipe repairs at the intersection of SE Holgate and SE 25th Avenue.

Environmental Services has begun a new project in the Brooklyn Neighborhood to extend the public sewer on SE 13th Avenue between Rhine and Pershing Streets and on SE 15th avenue between Rhone and Pershing Streets.

  • This work is part of the City of Portland’s ongoing effort to provide residents with sewer connections that comply with city code. The project will also help protect public health, property, and the environment by increasing the capacity of the public sewer system and reducing the potential for basement backups.
