Balch Creek Trash Rack Pre-Design

Environmental Services works throughout the city to protect water quality and the environment. Balch Creek, in northwest Portland, runs above ground for approximately 3 ¼ miles and then enters a pipe in Macleay Park. From that point on, the creek flows underground through the pipe until it reaches the Willamette River.

At the point in Macleay Park where Balch Creek flows into the underground pipe, a trash rack catches large debris to protect the pipe from backing up or clogging (see photo). Environmental Services is assessing the condition of the trash rack and considering ways to reduce future maintenance needs.

Next Steps

When the bureau completes a structural assessment and develops alternatives for repair, the project team will determine whether repairs are required. If they are, the team will begin designing modifications. Construction is tentatively expected in 2017. During construction, the city will maintain access to the trail near Balch Creek.
