I don't think we can both consider FEMA's 1% flood risks and also assume no longer know what plausible is with these storms.

I think it's safe to assume given recent storms that the 1% floodplains are _underestimating_ the risk

It sounds like you know what is plausible then though. Its plausible that 1% is and underestimate and implausible that its an overestimate.
