Southeast Portland

Stormwater Management Improvement Project

SE Portland


CONTACT:       Ashley Tjaden, 503-823-5281,

Environmental Services has completed a project in your neighborhood (see map below). Crews finished 2 months ahead of schedule in March 2015. Two Green Street Planters were constructed to help manage stormwater runoff. Green Street Planters filter the rainwater run-off before it enters into the system. This project also modified several sumps, also called underground injection control (UIC) structures. Sumps are perforated pipes installed vertically underground that collect stormwater runoff from streets and allow water to soak into the ground. This project removed some sumps and adjusted the depth of others to comply with state standards.

The work in your area was part of a city-wide project that modified more than 50 sumps in several Portland neighborhoods. Construction in all neighborhoods was completed by two months ahead of schedule in March 2015.

Environmental Services changed the original plans for this project by removing a number of green street planters from the design and opting to install sedimentation manholes connected to sumps. The manholes remove sediments from runoff and the clean water then flows into the sumps and soaks into the ground to replenish groundwater.
