Stephens Creek Outfalls Repair Project

Updated August 13, 2018Sign Up for Email updates

Environmental Services anticipates construction to begin in August to repair or replace two outfall pipes (see map) that carry stormwater runoff to Stephens Creek. The outfalls are deteriorated and contribute to erosion in Stephens Creek. The project will protect water quality and stream health, reduce erosion and rehabilitate riparian areas. The work will build upon previous projects along Stephens Creek, including habitat improvements at its confluence with the Willamette River.

Stephens Creek

Stephens Creek flows mainly above ground from its headwaters near Stephens Creek Nature Park to the Willamette River, just north of the Sellwood Bridge. The Stephens Creek subwatershed covers 754 acres of southwest Portland. The creek provides riparian habitat and stormwater conveyance in southwest Portland.

When it rains, stormwater runoff from streets and other hard surfaces flows into the creek. Outfall pipes convey stormwater and street runoff to the stream. This project will improve the function of the three outfalls on the map above.
