Flooding poses a grave threat to property and the safety of human communities. Urban planning efforts and guidance can have an important influence on the vulnerability of development in hazardous areas. This study is the first to use Hierarchical Linear Modeling (HLM) to investigate the influence of local planning capacity and other contextual factors on the integration of hazard mitigation policies and building of resilience across community 'networks of plans' in six US coastal cities. Findings indicate significant variation across cities regarding plan integration to enhance resilience. Communities with larger proportions of renters and lower socioeconomic status are shown to be less likely to incorporate hazard mitigation policies in local plans, controlling for community planning capacity. We also find evidence that communities with prior hazard experience are more likely to have resilience-focused plans, even in physically vulnerable neighborhoods which, in the absence of recent hazards, are actually less likely to receive positive policy attention. The study concludes by discussing the results and offering recommendations to inform more effective approaches as practitioners reevaluate their plans and work to foster more coordinated mitigation efforts across local networks of plans.

洪水对财产和人类社区的安全构成严重威胁。城市规划工作和指导可以对危险地区发展的脆弱性产生重要影响。本研究首次使用分层线性模型 (HLM) 来调查地方规划能力和其他背景因素对美国六个沿海城市跨社区“计划网络”的减灾政策整合和复原力建设的影响。调查结果表明，不同城市在计划整合以增强弹性方面存在显着差异。租户比例较大和社会经济地位较低的社区被证明不太可能将减灾政策纳入当地计划，控制社区规划能力。我们还发现有证据表明，具有先前灾害经历的社区更有可能制定以恢复力为重点的计划，即使在身体脆弱的社区，在没有近期灾害的情况下，实际上不太可能得到积极的政策关注。该研究最后讨论了结果并提供了建议，以便在从业者重新评估他们的计划和工作以促进跨本地计划网络的更协调的缓解工作时提供更有效的方法。
