Are you talking short term or long term?  Short term PR order evacuations, just like in Huston and Florida.  Long term there has been call to move the entire population into the mountains (thanks NY Post) -- kinda like telling coast folks here they have to move to the mid-west.  Can't say Houston nor Florida have done much either in that respect either (other than be the bastions of climate change deniers). Houston has had explosive growth often into known flood prone areas.  Florida, where the average elevation is 6', maybe we should just shut the whole thing down.  Either way, since none of these places do much for long term preparedness, why does Houston and Florida get the priority?
