 Proposals by agencies such as Metro, the regional government of the Portland metropolitan area, and the U.S. Army Corps of Engineers in the 1970s and 1980s to control Johnson Creek flooding were abandoned after groups of residents objected to every proposal.In 1990, the City of Portland formed the Johnson Creek Corridor Committee from multiple agencies and citizen groups with varied interests related to the watershed.Led by the city's Bureau of Environmental Services, the combined groups in 2001 produced the Johnson Creek Restoration Plan to reduce flooding, improve water quality, and improve fish and wildlife habitat.
