The history of planning in Oregon in the latter part of the 20th century is in many respects a history of the state attempting to reassert its interests in local planning and zoning after having granted the power to plan and zone to local governments early in the 20th century. The Oregon land use planning program evolved as a means for ensuring that state interests in the use of resource land and the prevention of sprawl were carried out meaningfully through local planning and zoning. Rather than a single state plan, Oregon has instead relied on the “quilt” of local plans covering the state to advance state land use interests. Oregon has achieved measurable success with this approach, but many issues remain.
