We employ a mail survey of private developers that uses conjoint choice experiments and Likert-scaled attitudinal questions to examine preferences for policy instruments and incentives intended to encourage brownfield cleanup and redevelopment. Our analysis suggests that developers judge public hearing requirements at brownfield redevelopments unattractive, but that they place a relatively high value on liability relief--from both cleanup costs and claims by third parties. Reimbursement of environmental assessment costs is not particularly attractive. We also find considerable heterogeneity among developers in the value they place on these incentives, depending on their experience with contaminated sites.
