Stephens Creek Outfalls Repair Project

Updated November 6, 2018Sign Up for Email updates

Environmental Services is finishing up 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

Environmental Services staff notify the public in advance of the construction activities, provide information throughout the project, and work to resolve problems during construction. Our intent is to identify concerns and minimize disruption as much as possible while completing these necessary projects. Now that the work is almost completed in your area, we ask for your help to measure how we did.

Please complete this survey online at to help assess the effectiveness of our public involvement and community outreach efforts. You will also be receiving this survey in the mail which you can fill out and send if that is easier.

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.

Construction Schedule

Crews are continuing to put the final touches on construction throughout the entire project area and will be doing final paving and restoration in the coming weeks.

Please be aware that schedules are also subject to change due to a variety of factors, including conditions underground, weather, traffic impacts and subcontractor and materials availability.

Typical work hours are 7:00 a.m. to 6:00 p.m. Monday through Friday, but the contractor may schedule work during the same hours on Saturdays.

What to Expect During Construction

  • Safety is our top priority for every construction site. You can help keep the area safe by staying clear of all construction activities and keeping children, pets and vehicles out of construction areas.
  • Construction creates noise, vibration and dust and disrupts normal neighborhood activity.
  • You should expect traffic delays in and near the work area. Please observe traffic control signs and follow the directions of flaggers. The contractor will maintain local access to all properties, but construction may impact normal use of your driveway or entrance to your business
  • On‐street parking will be restricted in and near the work zones to create a safe work environment and to stage equipment and materials.
  • Some equipment and materials will be stored on your street or nearby streets overnight.
  • Sewer, water, and other utilities will remain in service during construction.
  • Typical work hours are 7:00 a.m. to 6:00 p.m. Monday through Friday, but the contractor may schedule work during the same hours on Saturdays.
  • Construction schedules can change due to a variety of factors, including conditions underground, weather, traffic impacts, subcontractor schedules and availability of materials. These same variables may cause periods of inactivity during construction phases.
