Plans and Studies
Plans and Studies
Much of the interest in Johnson Creek Watershed management is linked to Johnson Creek’s history of frequent flooding. The watershed's complexity influences the way we plan for flood mitigation, natural resource management, housing development, and urban renewal.
Several individuals and organizations, local watershed councils and business groups have helped Environmental Services identify restoration priorities in the Johnson Creek basin. The documents on this website and studies listed below represent only a portion of the effort that has been devoted to resolving the flooding and environmental issues in the watershed.
Many of these documents are on file for public review in the Government Documents room at the Millar Library at Portland State University.
