Stigma assessment: the case of a remediated contaminated site

Abstract

The “stigma” associated with remediated contaminated land is the blighting effect on property value caused by perceived risk and uncertainty. Uncertainties relate to negative intangible factors such as the inability to effect a total “cure”, the risk of failure of the remediation method, the risk of changes in legislation or remediation standards, the difficulty in obtaining finance, or simply a fear of the unknown. Post‐remediation “stigma” is the residual loss in value after all costs of remediation, including insurance and monitoring, have been allowed for. It equates to the difference in value between a remediated contaminated site and a comparable “clean” site with no history of contamination. The initial results from a study of the market sales data of post‐remediated vacant residential land along the Swan River, in Perth, Western Australia, from 1992‐1998 are summarized. The aim of this ongoing research is to estimate the amount of “stigma” arising from a site’s contamination history and measure the effect of this on residential property values of remediated property. The results show that while a site’s contamination history impacts negatively on property prices, the price decreases are offset by the positive influence on price from additional amenities provided in the case study neighbourhood.
