Oregon's statewide land use planning program was created in 1973 with the passage of the Oregon Land Use Act.
"The enactment of Senate Bill 10 in 1969 was a crucial step on the path to Oregon’s landmark Senate Bill 100, passed in 1973, and the adoption of the goals that are the heart of the state’s land-use planning program. Oregon was the second state in the nation, after California, to mandate local government plan-making. SB 10’s requirement that local governments also zone all the land within their jurisdictions —California did not mandate zoning—was a first in the United States. Prior to 1969, Oregon had enabled local governments to plan and zone, but doing so remained a local choice. The statutory appearance of statewide land-use planning goals in SB 10 was unprecedented, as was the stipulation of a deadline and the authorization for the state to take on what had always been a local prerogative if a local government failed to comply."
