RAPID: Effect of Hurricane Florence on Homeowner Willingness to Engage in Flood Risk Mitigation and Buyout Contracts

由于未来自然灾害发生的地点和时间都是未知的，因此很难在灾害发生之前、期间和之后安排研究时间对受影响的人口进行抽样调查。因为一些好运气，这个研究项目可以做到这一点。在飓风佛罗伦萨登陆之前和期间，研究小组已经在进行一项在线调查。调查的目的是确定房主对房屋买断计划（购买和摧毁高洪水风险的房屋）和洪水缓解计划（补贴高洪水风险房屋的加高）的偏好。相当一部分样本来自飓风佛罗伦萨预测路径内的地区。这个快速反应研究（RAPID）项目将在飓风发生后立即（事件发生后1-2个月）和更遥远的未来（事件发生后约6个月）调查相同的受访者。这种方法，结合数据的地理位置的属性，将提供一个独特的理解如何地理接近灾害事件影响房主偏好不同类型的风险降低策略，以及如何随着时间的推移，这些偏好演变的事件和相应的新闻报道和恢复工作与它相关的变得更加遥远的受访者的记忆。这一科学研究的贡献，从而支持NSF的使命，以促进科学的进步和提高我们的国家福利。在这种情况下，好处将是洞察，以改善管理的家园洪泛平原，这可以挽救生命，减少经济损失。本项目的目的是确定的影响，人口，位置和合同属性的可能性，房主采用洪水缓解或替代将接受收购（买断）要约。该调查的结构是一个选择实验，收集了房主，洪水经验，洪水风险的看法，和财产的物理地址的额外的家庭层面的数据。除了飓风佛罗伦萨的洪水淹没地图外，酒店地址还将用于识别公共记录、高程和FEMA洪水区指定中的结构特征。这个RAPID项目将扩展以前的调查数据，重新调查200个原始受访者，并收集额外的400个响应，以创建一个小组，该小组将被调查两次，以判断观念的变化。这个奖项反映了NSF的法定使命，并已被认为是值得通过评估使用基金会的知识价值和更广泛的影响审查标准的支持。

Because the location and timing of future natural disasters are unknown, it is difficult to time a research study to sample an impacted population prior to, during, and after a disaster occurs. Because of some good fortune, this research project can do exactly that. The research team was already administering an online survey prior to and during the landfall of Hurricane Florence. The goal of the survey is to identify homeowner preferences related to home buyout programs (purchasing and destroying homes with high flood risk) and flood mitigation programs (subsidizing the elevation of homes with high flood risk). A substantial portion of the sample came from areas within the predicted path of Hurricane Florence. This Rapid Response Research (RAPID) project will survey the same respondents in the immediate aftermath of the hurricane (1-2 months after the event) and the more distant future (~ 6 months after the event). This methodology, combined with data on the geospatial location of the properties, will provide a unique understanding of how geographic proximity to a disaster event influences homeowner preference for different kinds of risk reduction strategies, as well as how these preferences evolve over time as the event and corresponding news coverage and recovery efforts associated with it become more distant in the memory of respondents. This scientific research contribution thus supports NSF's mission to promote the progress of science and to advance our national welfare. In this case, the benefits will be insights to improve management of homes in flood plains, which can save lives and reduce economic losses.The purpose of this project is to identify the effect of demographic, location, and contract attributes on likelihood that the homeowner adopts flood mitigation or alternatively would accept an acquisition (buyout) offer. The survey is structured as a choice experiment with additional household level data collected on the homeowner, flood experience, perception of flood risk, and the physical address of the property. The property address will be used to identify structural characteristics in the public record, elevation, and FEMA flood zone designation, in addition to flood inundation maps for Hurricane Florence. This RAPID project will extend previous survey data, resurveying the 200 original respondents plus collecting an additional 400 responses to create a panel which will be surveyed two additional times to judge changes in perceptions.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
