In the late 1970s, an imaginary line was drawn around the Portland area. Inside the line, urban development could flourish. Outside that line the farms and forestland that characterize western Oregon would remain intact. This line, called the urban growth boundary, has saved much of the natural landscape that surrounds the city. But in the thirty years since the UGB was first drawn, it has expanded more than once. Now a lot of people in the region are saying it doesn't need to grow anymore.
