Businesses often dissolve and leave contaminated properties behind. An effective but underutilized tool for dealing with abandoned and environmentally contaminated sites is known as Insurance Archeology or Insurance Cost Recovery. If contamination identified through environmental assessments was caused by a known polluter, a claim may be filed against the polluting business' comprehensive general liability insurance policies. Insurers have been found liable for the cleanup costs even in cases where the policies were decades old. Join CDFA, our technical partners, and experienced brownfield communities as we discuss how Insurance Archeology works, when it might be useful, and how some communities have used it as a way to raise capital to address the cleanup and redevelop needs of a property.
