New Orleans flood in May, 1995
Various levees around the city burst under pressure of the water. Causing some parts of New Orleans to flood.
"the flood struck New Orleans"
New Orleans, Louisiana, has an average elevation of about 1 to 2 feet (0.3 to 0.6 meters) below sea level. Some areas of the city are slightly higher, but much of New Orleans is prone to flooding due to its low elevation and proximity to the Mississippi River and Gulf of Mexico. The city's elevation and geography play significant roles in its vulnerability to hurricanes and storm surges.

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.
