I just read an article that says only 15% of the people have it. It's so expensive in a flood plain most can't afford it. The coverage seems to be so limited too. Anything under 1st floor level isn't covered except necessary appliance, like a furnace. So i f you have a fixed up basement, not covered. During Katrina it stated that all federal assisstance maxed out at $30,000 per household.
