This study employs interviews, document review, and a national survey of local government officials to investigate the factors that influence the success of efforts to convert underutilized contaminated properties into greenspace. We find that the presence of contamination continues to be a concern despite federal and state efforts to ease liability fears but also that site and project features can overcome this hurdle. In particular, jurisdictions appear more likely to convert distressed properties into greenspace if recreational parks, rather than open space, are planned, sites are already owned rather than available only through tax foreclosure, and the state is perceived as being supportive of the conversion. In addition, mixed public-private funding and site locations in residential areas are more likely to attract community support for conversion projects.
