I don't know how to ask this question, really, but what do you say when you are the authority in a City that the question was not IF it would happen but WHEN - and you know that probably 20% of your population does not have private transportation and then you think it might happen and you issue an evacuation order that ignores the reality that 20% of your population has no way of obeying that order...
Was there a plan to let these people get on the city buses and help them to flee? Was the plan to let the city buses get washed away and the people with them?
