This is just nuts and is not going to help at all. And what insurance company will insure a home built on a flood plain. You know what will help with the housing build smaller homes on smaller lots. People don't need big houses. Look at the size of the war time homes that were built after WW2. Those places ware small and people had no problem living and raising a family in them. Why do home need to be 3-4000 sqft? It just a waste of space, materials, time to build, and never mind the cost of owning and maintaining one. Start building single story war time style homes that are no more than 1500 sqft on 25-30 ft wide lots. They can be built fast and inexpensive.
