richlevy, the "Hundred-year Flood" designation can be misleading. It is perfectly possible to have TWO "hundred-year floods" back to back, and Arizona is a really good place to prove that. The designation also can't take into account what might happen to your property if it is in the path of water from a dam higher above you which is overflowing or gives out because of factors which might not even apply where you are located (such as Auburn in California or various reservoirs and dams above some LA bedroom communities). Several government agencies will have topo maps you can look at if you want to do the research, but title companies and whatever agency approves Building Permits should have plenty of documentation of what is a flood plain and what is not.
