Yes the government should buyout homes that are repeatedly flooded. If a home has repeatedly flooded, odds are it will flood again. I assume an actuary can calculate the odds. If it is determined to be economically more beneficial to buy a homeowner out than to repeatedly repair a home then do it and don't allow future development on the property. I have been helping with the removal of drywall in homes damaged Harvey. I am in the same neighborhoods I was in during the last flood, 15 months ago. The home owners do not have the wherewithal to move to a new home on their own. This is when I think the government should step in and move them. This would be a good use of my taxes.
