Reason.com talks about a family in Sacramento, CA that can't rebuild their home after a fire. Simply, the house is in a floodplain and FEMA regulations after Hurricanes Katrina and Sandy, the FedGov has been looking at floodplains.
PawPaw has been covering floodplains since 2005 and the simple truth is that lots of land in Louisiana is considered floodplain. I've lived in floodplains, and I've been flooded out. I understand why the FedGov doesn't want to insure folks who build in places where water might get in the house. It's hugely expensive.
Still, folks like to live near water, we love the ocean, and we tend to forget that every so often a storm comes along and our lives go sideways.
I'll bet that a lot of the folks who got flooded in New Jersey, New York and assorted locales during Sandy are learning that they're in a floodplain. One good sign is if the water comes in under the door. If that happens, you live in a floodplain and your life just got hugely complicated.
