The TriMet district serves portions of the counties of Multnomah, Washington, and Clackamas; it extends from Troutdale to Forest Grove east to west, and from Sauvie Island to Oregon City and Estacada north to south. This series of Maps examines land use in the TriMet district, and helps one to understand population density and spread in comparison to open space use.
