People who have roots there generations deep aren't going to give up without a fight. They just have to find a way to make it worthwhile to stay in the neighborhood. However, the old system of levees and pumps is probably history.
Maybe they could turn it into an American Venice.
If insurance co's consider it too high a risk (it is) they won't have a choice.
The Italian Venice isn't hurricane proof. It is not even tropical storm proof. Ditto the Netherlands.
That was my thinking--let the lake and river do what God intended and we have another Venice!
