it is almost impossible to plan for any, and all, contingencies. If the pumps didn't fail, then it would be because the levees couldn't handle a Category 4 hurricane. To take levees that would handle a Category 3 hurricane, and make them so they can withstand a Category 5 Hurricane, would probably triple their overall size, and cost, and even then they wouldn't be considered failsafe. There's always going to be a weakness somewhere. Bush just approved the massive Energy Bill, replete with a lot of pork barrel projects. I haven't read the bill but it might be interesting to see if there was anything in it for New Orleans, and what else they had in it for Louisiana. It should probably be on the internet; when I have time I'll see if I can find anything.
