项目摘要

Nearly 41 million Americans are at risk of flooding, and new homes continue to be built in flood-prone areas across the country. Federal, state, and local governments can use a range of policies and programs to limit or reduce construction in floodplains and promote development in safer areas. This award supports research to explore why some communities have been able to use these tools to grow without building in floodplains and why others have not. The researchers develop an index to identify communities who have successfully limited flood-prone development, and use case studies to explore the contexts, actions, and policies that enable towns to successfully limit flood exposure. As climate change leads to more intense storms and higher sea levels, effectively managing development in floodplains is increasingly critical to the health, prosperity, and well-being of communities across the United States. The research will enhance efforts by researchers, policymakers, and the public to build vibrant communities while limiting damage from climate extremes. The project supports collaboration and learning across flood management contexts, as well as the training of a diverse, inclusive next generation of climate adaptation researchers and practitioners.This project has three components. The first step is to measure floodplain development in municipalities across the United States, filling a critical data gap. Using real estate datasets, property buyout locations, and remotely sensed land use information, the net change in housing units and the increase in impervious surface from 2001 to 2016 are tabulated in relation to the regulatory 100-year floodplain. Raw measurements are then converted into development indices by scaling based on the municipality’s exposure to flood risk and total development. By creating standardized measures of floodplain development, this step enables strategic case selection and investigation of communities across a range of floodplain development outcomes, which is not currently possible. Second, patterns in floodplain development outcomes are analyzed using geographic, social, and economic factors. Third, the project will explain why communities differ in floodplain development outcomes using comparative case studies. Specifically, this component examines how the adoption, purpose, and implementation of legal and regulatory tools to avoid or retreat from floodplains shape floodplain development outcomes. Municipalities are selected in pairs: those that have limited floodplain development, and those that have not. Interviews and document analysis are used to assess what legal and regulatory tools were adopted, for what purpose, and how they were implemented, considering both tool design and enforcement. By first creating a way to measure development outcomes, this project provides a unique level of insight into both patterns in floodplain development and how and why legal and regulatory policies influence these outcomes.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.
近4100万美国人面临洪水风险,全国各地的洪水易发地区仍在建造新家园。 联邦、州和地方政府可以使用一系列政策和计划来限制或减少洪泛区的建设,并促进更安全地区的发展。 该奖项支持研究探索为什么一些社区能够使用这些工具在洪泛区发展,而不是在洪泛区建设,为什么其他社区没有。 研究人员开发了一个指数,以确定成功限制洪水易发发展的社区,并使用案例研究来探索使城镇能够成功限制洪水暴露的背景,行动和政策。 随着气候变化导致更强烈的风暴和更高的海平面,有效管理洪泛区的发展对美国各地社区的健康,繁荣和福祉越来越重要。 该研究将加强研究人员,政策制定者和公众的努力,以建立充满活力的社区,同时限制极端气候造成的损害。 该项目支持跨洪水管理背景的合作和学习,以及培训多样化、包容性的下一代气候适应研究人员和从业人员。 第一步是测量美国各城市的洪泛区发展情况,填补关键的数据空白。 使用真实的房地产数据集,物业收购位置和遥感土地使用信息,从2001年到2016年,住房单元的净变化和不透水面的增加与监管100年的洪泛区有关。 然后,通过基于市政当局面临的洪水风险和总体发展的缩放,将原始测量值转换为发展指数。 通过创建标准化的洪泛区开发措施,这一步骤可以在一系列洪泛区开发成果中进行战略案例选择和社区调查,这是目前不可能的。 其次,洪泛区开发成果的模式进行了分析,使用地理,社会和经济因素。 第三,该项目将使用比较案例研究解释为什么社区在洪泛区发展成果方面存在差异。 具体而言,这一组成部分审查如何采用,目的和实施的法律的和监管工具,以避免或退出洪泛区形状洪泛区的发展成果。 城市是成对选择的:那些有有限的洪泛区发展,而那些没有。 访谈和文件分析被用来评估采用了哪些法律的和监管工具,出于何种目的,以及如何实施,同时考虑到工具的设计和执行。 通过首次创建一种方法来衡量发展成果,该项目提供了一个独特的洞察力,既在洪泛区发展的模式,以及如何和为什么法律的和监管政策影响这些成果。这个奖项反映了NSF的法定使命,并已被认为是值得通过使用基金会的智力价值和更广泛的影响审查标准进行评估的支持。
