Does the government cover the bill since floods are typically referred to as “disasters”?
No, the area where your home is located must be formally declared a “disaster area.” This occurs less than 50% of the time (You have better odds of winning at roulette). Note that the government merely loans you money to repair your home…they don’t just write you a check! You will have to pay interest on that loan, which may cost more than paying for flood insurance yourself.
