A tentative plan developed by the U.S. Army Corps of Engineers calls for a large portion of Charleston, S.C., to be ringed by a storm-surge wall to defend the city’s downtown against future floods.

军团估计整个项目的成本为11亿美元。官员们说，“优化”计划更便宜，增加了弹性，并且比研究所考虑的其他方案具有更好的成本效益比。新利luck

查尔斯顿市中心位于阿什利河，库珀河和查尔斯顿港之间的大部分平坦，低洼的半岛。几家医院位于容易洪水的地区，有12,000多个建筑物在半岛上价值数十亿美元。即使没有暴风雨，该地区有时也会遭受潮汐洪水，而军团的研究警告说，沿海风暴在高潮中登陆“可能对社区造成灾难性的灾难”。新利luck

The Corps Charleston District began studying coastal storm impacts on the peninsula in 2018. The latestdraft feasibility report以及9月10日发布的环境影响声明提议在半岛周围建造一个12英尺高的暴风雨墙壁。

“它旨在为医学界以及所有居民和企业建立持久的沿海弹性，”指挥官和地区工程师上校在一份声明中说。

Most of the barrier would be a T-wall with concrete stem walls and pile-supported bases. The wall would tie into existing high ground like the historic Battery Wall. In the marsh, the barrier would be a combination wall similar to the Inner Harbor Navigation Canal Surge Barrier in New Orleans, consisting of continuous vertical piles on the storm surge side and battered piles on the other side, connected by a concrete cap. There would be tidal flow gates for vehicles and pedestrians that could be closed ahead of anticipated storms. On the inner side of the wall, pump facilities would prevent flooding.

该计划还要求在某些地区创建基于牡蛎礁的生存海岸线，以减少风暴对天然海岸线和沼泽的影响。

这并不是查尔斯顿（Charleston）唯一为减轻洪水而采取的策略。正如E新利lucknr先前报道的那样，该市已经进行了排水改进项目18luck官网designed to deal with sea levels that are as much as 2 ft higher than current levels.

A public review and comment period on the Corps proposal is open through Oct. 25. After that, the agency anticipates releasing a final report in May 2022 before submitting the findings and plan to Congress.
