Building Social Equity into Floodplain Buyouts
(2021-04-30) Lipuma, Sarah
Increasingly frequent flood events have generated greater attention to voluntary floodplain buyouts, a tool to mitigate flood hazards by permanently moving people and properties out of harm’s way. While buyouts hold the promise of reducing flood risk by allowing the land to be used to store stormwater, they can also repeat inequitable practices of the past that have displaced vulnerable communities. Through a literature review, this study discusses the knowledge to date at the nexus between flood risk, social equity, and buyouts. The study uses geospatial tools to identify possible parcels for buyouts in a North Carolina town by focusing on the level of flood risk and proximity to natural areas. The resulting buyout scenarios are compared using a social vulnerability index and physical risk factors. The study concludes with recommendations to land use planners and floodplain managers at the state level for buyout decision-making. Incorporating social vulnerability information into buyout criteria will be valuable to administrators of buyout programs to identify the most at-risk populations, prioritize equity, and direct government funding to buyouts that benefit the entire community.

Were the Post-Sandy Staten Island Buyouts Successful in Reducing National Vulnerability?
(2017-04-28) McGhee, Devon
An increasingly common post-disaster mitigation approach, home buyout programs are generally intended to reduce vulnerability to future disasters. However, to date, there has been no quantitative evaluation of whether or not coastal buyout programs are successful in reducing vulnerability. Through a change in vulnerability analysis, this study quantifies the success of the Staten Island buyout program in reducing the nationwide vulnerability of people and property to coastal flood hazards. Results show an increase in overall vulnerability, which includes exposure and social vulnerability, for 99% of the buyout participants studied. Buyout participants tend to relocate within five miles of their origin addresses, move to areas with higher levels of poverty, higher population density and greater percentages of individuals over 65. This analysis concludes that significant uncertainty remains with respect to whether or not the Staten Island buyout program met its objective of reducing the vulnerability of people and property to coastal flood hazards.
