Columbia River Development Drawings
The Columbia South Shore area in Multnomah County runs along part of the ‘Great Water’ (imaɬ or iyagaytɬ imaɬ in the original Chinookan language). While urbanization has modified the environment dramatically, the land maintains some of its original natural assets and harbors archeological resources.
A set of development drawings in Multnomah County Archives depicts a proposed recreation area for the South Shore. The plans originated from a project proposal sourced by the Multnomah County Commission in 1970. They depict land along the river near Portland International Airport and Government Island. They may have been developed in response to controversial efforts to expand the airport in the late 1960s and early 70s.
