...another "once in a hundred year" flood. .
As a Certified Floodplain Manager (yes, there really is such a thing), a one-hundred-year floodplain does not mean it floods on average once every hundred years. That that means is there is an annual 1% of flooding (the reciprocal of 100). That does not seem like much, but if you have a 30-year mortgage on a home in that floodplain, you have approximately a 1 in 4 chance of that flooding (at least once) over the course of that mortgage. Basically, do not buy a home in a floodplain--the odds are not good. For those in the USA, if you want to know if your home is in a floodplain, go here:

And one note on flood maps: they are made from historical data. That means with climate change those maps are underestimating risk (assuming they are accurate from the get go).
