I think you are the one that is painting with a broad brush here. I actually know a thing or two about floodplains since I deal with them from time to time in my job. But hey, I probably don't as much as you.
There are categories of flood plains, say for example 100 year and 500 year flood events. Inherently this means some of these areas will flood more often than others.
Some of these even carry different levels of Flood Insurance based on risk. Go [censored]ing figure, eh. So when you build in the area that is more prone to the event chances are good that you may experience such an event. Wow, what a concept.
Now like the Grand River and the good folks I was referencing who go back year after year just to be flooded out and bailed out the next year, something has to make you go hmmmm. Really, how often do insurance carriers have to pay out and local municipalities have to provide services to these folks? Hey, there is no cost in any of this right?
So hey, build wherever the [censored] you want and just wait for the good old government and insurance companies to bail your ass out....Take absolutely no responsibility in anyway, shape, or form for the decision you made on where to build and live, because here in good old America we will rescue you from your decision.....
And you don't think that blowing the levees and flooding all those acres of farmlands and so on is going to cost anything and no one is going to blame the corp for any of that.....right!
