雨水基础设施可以在排水没有障碍物的情况下管理降水引发的洪水。由于风暴或潮汐造成的水位升高，沿海地区越来越多地遭受经常性洪水，但水位升高对沿海雨水基础设施的淹没尚未得到广泛评估。我们保守地估计了美国大西洋沿岸沿着城市的雨水基础设施淹没情况，方法是使用道路上的高潮洪水（HTF）区域作为替代。我们还模拟了四个北卡罗来纳州城市的雨水基础设施淹没，并测量了其中一个城市的基础设施淹没。结合不同尺度的方法提供了背景，并允许广泛估计雨水基础设施淹没的范围。我们发现，大西洋沿岸沿着有137个人口普查指定的城市地区的道路面积受到HTF的影响，受HTF影响的道路总面积的中位数为0.16%（IQR：0.02%-0.53%）。根据2010年人口普查区的数据，每个城市地区居住在公路上有HTF的人口普查区的人数中位数为1，622人（IQR：366- 5，779）。我们估计，总共有超过200万人居住在美国大西洋沿岸沿着道路上出现HTF的人口普查区。模拟结果和水位测量结果表明，地下雨水基础设施的广泛淹没可能发生在平均潮差内的水位。这些结果表明，雨水基础设施淹没沿着美国大西洋沿岸可能是广泛的，影响了大量的人，经常发生，并增加城市洪水的发生。
Stormwater infrastructure can manage precipitation‐driven flooding when there are no obstructions to draining. Coastal areas increasingly experience recurrent flooding due to elevated water levels from storms or tides, but the inundation of coastal stormwater infrastructure by elevated water levels has not been broadly assessed. We conservatively estimated stormwater infrastructure inundation in municipalities along the Atlantic United States coast by using areas of high‐tide flooding (HTF) on roads as a proxy. We also modeled stormwater infrastructure inundation in four North Carolina municipalities and measured infrastructure inundation in one of the modeled municipalities. Combining methodologies at different scales provides context and allows the scope of stormwater infrastructure inundation to be broadly estimated. We found 137 census‐designated urban areas along the Atlantic coast with road area impacted by HTF, with a median percent of total road area subject to HTF of 0.16% (IQR: 0.02%–0.53%). Based on 2010 census block data, the median number of people per urban area that live in census blocks with HTF on roads was 1,622 (IQR: 366–5,779). In total, we estimate that over 2 million people live in census blocks where HTF occurs on roadways along the US Atlantic coast. Modeling results and water level measurements indicated that extensive inundation of underground stormwater infrastructure likely occurs at water levels within the mean tidal range. These results suggest that stormwater infrastructure inundation along the US Atlantic coast is likely widespread, affects a large number of people, occurs frequently, and increases the occurrence of urban flooding.
