The French Quarter is higher than the average elevation of New Orleans; in fact it is above sea level. It took enough time for the water to enter New Orleans that by the time the flood crested Katrina's storm surge had passed, and no areas above sea level could have flooded. Additionally, the levee near the French Quarter remained intact.
