In 1999, Wisconsin passed the Smart Growth Law, requiring local governments with land use planning authority to design neighborhoods that reflect Smart Growth Principles. These principles, some of which may lead to increased physical activity, include neighborhood designs with a range of transportation choices, the redevelopment of existing land and structures and the utilization of more compact, efficient development patterns. This progressive law makes Wisconsin an ideal setting to study the process of reforming comprehensive plans and zoning codes that promote active living. In this study, the Metropolitan Institute at Virginia Tech will partner with The 1000 Friends of Wisconsin to study both the state wide and local policy change processes. Special attention will be paid to the relationship between state and local governments implementing the change. Researchers will then study implementation of the plans and ordinances in 10 specific localities to assess if they have resulted in development that encourages active living.
