" Well, yes and no. Repair and reconstruction prices tend to go up in
the wake of a natural disaster; that's basic supply-and-demand at
work.

While we're on this topic, does anyone know to what extent (and in
what form) would FEMA offer any relief?

While FEMA MIGHT offer relief in these areas, FEMA shouldn't give any money
to anyone who willing lives in an area already known for certain types of
natural disasters. That's what insurance is for. If you can't afford the
proper insurance, then pick someplace else to live.

FEMA only has money because it's taken it from many of us to pay you for
your lack of foresight.
