Yes, this is one of the areas that are flooded seasonally, and devastated every 20-50 years. To put it into perspective, the tidal range in the pacific islands is around 2 feet. Yearly storm surges go from 5 to 20 ft (hurricane required for the upper range). This is why there are surprisingly few buildings at risk [1]. Nobody builds/rebuilds where frequent destruction happens. People are smarter than that. People will slowly move inland, which is unfortunate to those at the perimiter. But I don't think this is "doom".
