As climate change increases flood risk, there is growing recognition that the multiple plans cities adopt often work at cross purposes and encourage development in areas at risk of current and future flooding. There have been calls for a more coordinated approach to planning for current and future flood risks, but is planning rising to the challenge? We apply the Plan Integration for Resilience Scorecard (PIRS) methodology to spatially evaluate policies that would impact physical vulnerability to flooding in the network of different city plans that shape land use and steer development in Boston, MA and Fort Lauderdale, FL. Unlike previous applications of this approach, we look at how the plan network is changing over time. Between 2015 and 2019, attention on climate change grew in both cities, as did the number of plans and policies across the network with the potential to decrease physical vulnerability. New types of plans, such as climate change adaptation plans, play an important role in reducing flood risks. However, plans perpetuate past disparities in policy attention. As the first study to analyze how city networks of plans and their potential impact on resilience evolve over time, this work has important implications for planning scholarship and practice as well as hazard and climate change governance more broadly.

随着气候变化增加洪水风险，人们越来越认识到，城市采用的多种规划往往相互矛盾，鼓励在当前和未来面临洪水风险的地区进行开发。有人呼吁采用更协调的方法来规划当前和未来的洪水风险，但规划是否正在应对挑战？我们应用弹性计分卡计划整合 (PIRS) 方法来空间评估影响物理脆弱性的政策，这些政策会影响不同城市规划网络中的洪水物理脆弱性，这些规划塑造了马萨诸塞州波士顿和佛罗里达州劳德代尔堡的土地利用和引导发展。与此方法以前的应用不同，我们着眼于计划网络如何随时间变化。2015 年至 2019 年间，这两个城市对气候变化的关注都在增加，整个网络中可能减少物理脆弱性的计划和政策的数量也是如此。新型计划，如气候变化适应计划，在降低洪水风险方面发挥着重要作用。然而，计划延续了过去政策关注的差异。作为第一项分析城市规划网络及其对复原力的潜在影响如何随时间演变的研究，这项工作对规划学术和实践以及更广泛的灾害和气候变化治理具有重要意义。
