Metro Portland's Internal Growth Dilemma
"The disagreement is not a concern solely for the wonks of the world. The greater Portland area is projected to attract a million more residents during the next 20 years and will have to accommodate the increased jobs, housing, traffic, infrastructure and services that accompany population growth.
By designating urban and rural reserves, regional leaders hoped to offer 40- to 50-year certainty on land-use decisions. Developers would know far in advance where urban areas would grow. Farmers could make crop or equipment purchase decisions, knowing development wouldn't infringe for decades to come. Planners at all levels of government would be able to think ahead regarding utilities, schools, parks and other services."
