Oregon’s pioneering 1973 land use law created a statewide system for land use planning, requiring local governments to regulate zoning in accordance with state-level goals. Under the law, urban areas like Portland are required to set an “urban growth boundary” to contain urban and suburban development. Outside the boundary, open space and agricultural land is preserved.  Portland’s urban growth boundary extends into Multnomah, Clackamas and Washington counties, and is administered by the regional government Metro.
