Cedar Mill Creek Flood Remediation Collaborative

Cedar Mill Creek and its major tributary North Johnson Creek drain a forested watershed on the west side of the West Hills mostly in Washington County. Because much of the watershed has been converted to urban uses, storm water runoff has been adversely affected and flooding occurs throughout the creek corridors even during relatively small rainfall events. The purpose of this collaborative effort was to enhance the natural functions of Cedar Mill Creek and North Johnson Creek corridors and manage flood risks in a manner that provides high quality natural habitat, while reducing flood hazard impacts on flood-prone residential and commercial properties.

On October 9, 2018, members of the Cedar Mill Creek Flood Remediation Collaborative signed a Declaration of Cooperation detailing each participant’s commitment of time and resources to address flooding issues in the area. More than forty participants attended the signing event.
