Katrina fall-out

I wonder if the insurance companies (and the federal government) will
FINALLY wake up to the fact that building permanent structures below
sea-level in a hurricane zone is folly?

It is time for the federal government to tell local and state
governments that federal tax dollars will no longer be spent to rebuild
in areas like coastal plains (flooding, storm surge), river valleys
(flooding), earthquake faults (self explanatory), unstable hillsides
(mud slides), etc., which are zoned residential.
