Critical Review of National Flood Policy Outcomes

Abstract

Abstract Populations are increasingly exposed to natural hazards due to expanding development and climate change. This exposure is exacerbated by sociodemographic and socioeconomic factors limiting resources for disaster mitigation and recovery. Federal disaster assistance is crucial for communities in the wake of catastrophic events by supplementing local resources. However, recent research suggests that federal disaster assistance may exacerbate existing inequality across social groups. The most pervasive and costliest disaster in the United States is flooding. The federal government maintains multiple programs supporting flood mitigation and recovery, yet a comprehensive understanding of how these programs may foster inequitable outcomes is lacking. This paper uses a systematic review of federal flood policy literature over the last decade to fill this gap and identify patterns that may contribute to inequitable outcomes. Results suggest that despite over 100 flood-related disasters occurring over the past decade, the effectiveness of flood policies across social groups is relatively unstudied. And when studied, federal policies themselves do not explicitly lead to inequitable outcomes. Instead, we conclude that policies prioritize equality over equity and do not overcome systematic oppressive and racist decision-making. These findings further the understanding that social vulnerability to natural hazards is a complex and contextual issue.
