The Fifth Amendment to the U.S. Constitution states that government shall not take private property except for public use and with just compensation. Officials from national organisations and state and local governments cited various purposes for which eminent domain can be or has been used, including the building or expansion of transportation-related projects; the elimination and prevention of conditions that are detrimental to the physical, social, and economic well-being of an area; remediation of environmental contamination; and economic development. This book provides information on the purposes for and extent to which eminent domain can be and has been used; the process states and select localities across the country use to acquire land, including by eminent domain; how the use of eminent domain has affected individuals and communities in select localities; and the changes state legislatures made to laws governing the use of eminent domain from June 2005 through July 2006.
