This year, the Portland metro area recognizes the 40th anniversary of Senate Bill 100’s signing into law by the late Governor Tom McCall. This landmark legislation paved the way for Oregon’s renowned land use planning system and pioneering urban growth boundaries. Since the implementation of the state’s first urban growth boundary (UGB) in the 1970s, the UGB has become a model for anti-urban sprawl efforts nationwide and has helped to preserve vast areas of agricultural and forest lands statewide. Since its inception, however, the UGB has excited controversy, especially in the state’s most populous area: Portland metro. This year, as many celebrate the birth of the UGB and its many successes, a largely rural community south of Portland and its surrounding municipalities continue to be embroiled in a decades-long conflict over the potential expansion of the boundary and the prospect of urbanization.
