作为社区恢复和减灾的政策工具,自愿财产收购在美国洪灾后发挥着越来越重要的作用。在2008年发生历史性洪灾后,爱荷华州锡达拉皮兹市制定了一项联邦政府支持的计划,用于收购1300多处受损财产。本文以雪松急流为例,从成本效益和社会公平的角度对洪灾后的财产收购进行了研究。为了评估经济可行性,在地块范围内进行了效益-成本分析。使用为洪灾恢复量身定做的社会脆弱性指数来评估社会公平。结果表明,在避免未来洪灾损失的基础上,物业收购是具有成本效益的,并优先考虑社会弱势社区。经济和社会双重分析揭示了联邦政府支持买断的能力,以支持全面的灾后规划和决策。
Voluntary property acquisitions are playing an increasingly prominent role in the aftermath of US flood disasters, as policy tools for community recovery and hazard mitigation. Following historic flooding in 2008, the City of Cedar Rapids, Iowa, instituted a federally supported program for the acquisition of over 1300 damaged properties. Using Cedar Rapids as a case study, this article investigates post-flood property acquisition from the perspectives of cost effectiveness and social equity. To assess economic viability, a benefit-cost analysis was performed at the parcel scale. Social equity was assessed using a social vulnerability index tailored to flood recovery. The results indicate that the property acquisitions are cost effective based on the avoidance of future flood losses, and prioritize socially vulnerable neighborhoods. The dual economic and social analysis sheds light on the capacity of federally supported buyouts to support holistic post-disaster planning and decision-making.
