Sounds like a good plan to me. Are you an engineer or just a reader of maps?
I stayed in a Holiday Inn Express last night.
Seriously, I was going to be a geologist but ended up going into systems. But I've kept studying these subjects. Sooner or later, the Atchafalaya is going to take over the flow of the Mississippi. We can both rebuild the city elsewhere to the west and prepare for that channel shift and compensate for subsidence with one plan. It was only a matter of time which sword was going to hit first. But raising levees and rebuilding the city in place leaves all three swords hanging.
