I believe it was only due to President Bush's pleading to the Governor of LA that they enacted a mandatory evacuation (not exactly "shouting from the rooftops" but certainly the same effect). It should have been a no-brainer, and things should have gone a lot more smoothly, especially with having Ivan last year as a dry run of the evacuation plans...It should have been clear with a city like that, facing the possible catastrophe of a Cat 4/5 demolishing the city, that city folks should have had detailed evacuation plans with last resort shelters outside the city being pre-arranged, and a plan to evacuate those withtout their own form of transport to said cities...From what I can tell, they are still scrambling to find places to keep the refugees once they are out of the city...
