Came across a well-detailed Katrina timeline   – the timeline speaks for itself. Here’s the introduction:

It is hoped that, by recording the events surrounding Hurricane Katrina’s destruction of New Orleans on August 29, 2005, some insight will be gained into the mechanism of disaster. We need to understand how Federal and local government, Republican and Democratic alike, could be so inadequate to a calamity that had been predicted for decades. What emerges from any attempt at doing so is no less than a damning account of corruption, indifference, racism, classism, oppression, ignorance, historical mistrust, and finally a near-total breakdown in all levels of American political and social institutions.
