Galveston, TX did it.
Yes they did. But Galveston is not and was not below sea level, it was just not very much above sea level. Still isn't really, but about 15-20 feet higher than it was, at least at the east end.
Galveston was swept by the tidal surge, not by floodwaters that poured in after the surge had breached a sea wall. It's also not built on silt deposits. It's limestone under the fill, IIRC.
