The effect of voluntary brownfields programs on nearby property values: Evidence from Illinois

Brownfields are properties whose redevelopment is hampered by known or suspected contamination and by concerns about associated liability. Because failing to redevelop brownfields may negatively affect welfare and the environment, a number of states have created voluntary programs to reduce liability risks and encourage redevelopment of brownfields. For clean or remediated properties, the state certifies that owners of such sites are not subject to federal or state liability under certain conditions. Certification could increase nearby property values because of decreased contamination risk and amenities associated with redeveloping the brownfield. This paper focuses on the Site Remediation Program in Illinois, and estimates the effect of brownfields certification on nearby property values. Employing several strategies to account for unobserved and time-varying variables that may be correlated with certification, I find that the entry and certification of a brownfield 0.25 miles away raises the value of a property by about 1% compared to an otherwise identical property.
