- 2014 Taylor & Francis. Population and land-use relocation in the United States contributes to the generation of many functionless, unmaintained historic structures. Many once-vital buildings have been removed, while others have simply been abandoned and left to decay or demolished through neglect. The National Trust for Historic Preservation in 2008 suggests that more than 500 communities are experiencing significant numbers of teardowns, but there is a lack of research on both the exact number of heritage structures that have fallen into neglect and the provisions necessary to prevent neglect. In response to growing concerns about the climbing rate of these structures, this paper assesses both the rationale behind the neglect of historic structures and current preventative techniques and policies. The purpose is to distil the requirements necessary for prevention of demolition by neglect into imperatives to guide future preservation policy.
