Stream Enhancement Along Ash Creek


Environmental Services is working with Portland Parks & Recreation to construct a stream enhancement project in the Ash Creek Natural Area/Taylor’s Woods portion of Dickinson Park. Construction started earlier this month and is expected to be completed by early September.

The key project goal is to protect an exposed sanitary sewer pipe, but we took the opportunity to stabilize the stream channel and improve in-stream habitat at key locations, which will help improve water quality and habitat in South Ash Creek watershed. To learn more about the current condition of the watershed visit our Fanno Creek Watershed Report Card website.

Construction is happening now when creek levels are low to minimize potential impacts to important fish, wildlife and habitat resources as required by state and federal regulations. This fall we will replant native plants in areas disturbed during construction and throughout the Ash Creek Natural Area.
