Coastal urban areas are experiencing the effects of sea level rise in the form of more frequent and intense flooding. Retreat from vulnerable at-risk areas and the creation of open green space that may be used for both storm water retention and enhanced recreational activities is a common mitigation strategy. This research presents a methodology for local governments to acquire privately held urban parcels to create green space, manage water, and enhance quality of life. This methodology is demonstrated by way of a case study of parcel acquisition in Portsmouth, Virginia. This research is generalizable in that it provides a science-based, general framework that may be used to guide local parcel acquisition policy in response to increasing risk posed by sea level rise and flooding. The research is practical and addresses both political and methodological hurdles in the identification of areas to be considered for buyout.
