随着洪水造成的财产损失继续增加，特别是在沿海地区，采取减轻这些损失的战略对于保护沿海社区的健康和安全从未像现在这样重要。正在考虑进行结构性和非结构性防洪活动，以缓冲在面临洪水风险的地区建造建筑物的不利后果。然而，很少有研究对洪水缓解措施的有效性进行，特别是在地块层面的非结构方法。我们的研究通过检查联邦应急管理局社区评级系统下采取的缓解活动对位于德克萨斯州休斯顿南部和加尔维斯顿湾附近的Clear Creek流域内多个社区的保险财产损失的影响，解决了这一关键知识的缺乏。具体而言，我们统计了1999年至2009年9,555个地块中社区采用的各种缓解策略减少洪水损失索赔的程度。结果表明，在社区一级采取的若干缓解政策为Clear Creek流域的房主节省了大量财产损失。
As property damage from flooding continues to increase, particularly in coastal areas, the adoption of strategies to mitigate these losses has never been more important to protecting the health and safety of coastal communities. Both structural and non-structural flood mitigation activities are being considered to buffer the adverse consequences of building structures in areas exposed to flood risk. However, little research has been conducted on the effectiveness of flood mitigation practices, particularly non-structural approaches at the parcel level. Our study addresses this lack of critical knowledge by examining the effect of mitigation activities adopted under the FEMA community rating system on insured property losses across multiple communities within the Clear Creek watershed located just south of Houston, TX and adjacent to Galveston Bay. Specifically, we statistically identify the degree to which various mitigation strategies adopted by a community reduce flood loss claims among 9,555 parcels from 1999 to 2009. Results indicate that several mitigation policies adopted at the community level result in significant savings in property damage for homeowners in the Clear Creek watershed.
