The City of Portland’s Bureau of Environmental Services is continuing our work to repair and replace critical sewer and stormwater infrastructure. Environmental Services will continue to provide information and updates on construction schedules and activities during the COVID-19 emergency. 

Updated September 22, 2020

City of Portland, Bureau of Environmental Services is designing a project to reconnect Johnson Creek with its floodplain near SE Deardorff Road. The project is part of a broad city effort to improve habitat conditions and reduce the impacts of flooding along Johnson Creek.

Schedule

This project is currently being designed. Construction is anticipated to begin in Summer 2021.

Upcoming Activities

In the coming months, city staff and consultants will visit the project site to conduct field investigations, take water and soil samples, mark utilities, and conduct other activities. These field visits will help the design and construction team design the project.

Project Details

The Cedar Crossing Restoration Project is a stream and floodplain restoration effort located on three city-owned properties adjacent to SE Deardorff Road. The project will build upon past vegetation restoration and include partial removal of the Works Progress Administration (WPA) walls that were built to straighten and restrain Johnson Creek. The project will addhabitat features such as logs to help slow down the speed of Johnson Creek. This will not only reduce downstream flooding and erosion problems, but also provide hiding places for fish and other wildlife. Native plantings along the banks will help shade the creek and keep it cooler in the summer and provide food and shelter for wildlife.

The project will:

  • Remove WPA wall and restore the creek’s connection with its floodplain.
  • Restore stream features and complexity to provide habitat for endangered salmon and other wildlife.
  • Protect and enhance wetlands.
  • Protect mature trees whenever possible and plant native trees and shrubs to increase the stream-side canopy.

Current efforts to restore Johnson Creek focus on returning it to a more natural state. This type of restoration provides a safe place for flood waters to spread out and soak into the ground. It also helps improve water quality and increases fish and wildlife habitat. Johnson Creek provides important habitat for coho and Chinook salmon, as well as steelhead and cutthroat trout. While these species still exist in Johnson Creek and its tributaries, their long-term survival depends on our ability to restore habitat and improve water quality.
