I am not an expert in this field at all -- I am making an educated guess based on the economics of the situation. Some places are potentially subject to a single incindent such as a hurricane, tornado, earthquake, etc. But NO has been exposed as inherently dangerous with no ability to redeem itself. It may be years before concrete may be laid on the ever-shifting sands.
NO is unique in it has entire (now aging) infrastructure dedicateted to keeping nature out.
I think the insurance compainies won't allow rebuilding on silt.
Be still my heart.....
"I am not an expert in this field at all -- I am making an educated guess based on the economics of the situation."
I live in the middle of what is called "Tornado Alley" which stretches from Texas up into Kansas and points north. There is a map I've seen (and can't find now or I'd post it, or a link to it) that shows the historical paths of tornados in Oklahoma since 1899, I believe it is: they often follow the same paths, not exactly but within bands... That May third tornado was followed a couple of years later by another one that went right down the same track, but not for the whole track, fortunately. On that basis, I expect some people would suggest abandoning Oklahoma, too.
