Stephens Creek Outfalls Repair Project

Updated April 22, 2019Sign Up for Email updates

Environmental Services has completed construction to repair or replace two outfall pipes (see map) that carry stormwater runoff to Stephens Creek. The outfalls were deteriorating and contributing to erosion in Stephens Creek. One outfall has been removed and replaced with several stormwater inlets and new pipes to manage a portion of neighborhood stormwater in the SW Custer and SW Canby streets area. Another outfall has been repaired in the Riverview Cemetery area off SW Taylors Ferry Road and 2nd Avenue.

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.

Developments of Note

A second phase of this project, which will repair additional outfalls in the basin, is currently in the early stages of design.

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.
