Were the Post-Sandy Staten Island Buyouts Successful in Reducing National Vulnerability?

Abstract

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.
