Keys to making urban growth boundaries work as a planning tool for controlling sprawl in US cities were identified in a session in the recent American Planning Association conference. Examples of urban growth boundaries were presented from Portland, Oregon; King County, Washington; and Denver.

Incentives can also be goven to those outside the boundaries. For a full discussion of the three examples click here.
