It will be interesting to see what will happen - I live 8.63 feet above mean sealevel. FEMA - yes FEMA will only let me improve my house 50% of the value of the structure. If I was at 9 feet - I could build till my hearts content.
Being that NO is below sea level - it will be very interesting to see what they do with the rebuild. Yes, it's a big port. Yes, you have the Mississippi River. On Sept. 8, 1900 Galveston was hit by a killer Hurricane that killed 6,000 people.

They shipped in earth and raised the whole island 15-8 feet - wonder if they would do that for new orleans?
