Hurricane Katrina made landfall on August 29, 2005, after chewing through the Gulf as one of the largest storms ever recorded. Wind damage along the Mississippi coast was catastrophic — entire coastal blocks vanished. But the world remembers New Orleans: levees and floodwalls failed, and lake and canal water poured into neighborhoods below sea level.
Engineering and Governance Failure
Investigations found design and maintenance flaws in the federal levee system. Evacuation worked for many who had cars; the poor, elderly, and sick were left behind. The Superdome and convention center became symbols of a nation that could send troops abroad but struggled to deliver water domestically. Roughly 1,800 people died.
A Changed Coast
Katrina reshaped FEMA, flood insurance, building codes, and coastal planning. Billions were spent on levee upgrades — the Greater New Orleans Hurricane and Storm Damage Risk Reduction System. Populations shifted permanently. For anyone studying hurricanes, Katrina is the lesson that social systems are part of the storm.
