Hurricane Katrina looms large in the history of American emergency management, both for what went wrong as the disaster unfolded and for the policy changes it triggered. As efforts to reform –and possibly rebalance –the U.S. emergency management system continue, it is essential to remember and heed the costly lessons of Hurricane Katrina.

Hurricane Katrina looms large in the history of American emergency management, both for what went wrong as the disaster unfolded and for the policy changes it triggered.

As the nation looks back on the disaster 20 years later, I believe as a crisis and emergency management specialist that it is more important than ever to remember Katrina’s lessons to avoid repeating past mistakes.

When Katrina hit New Orleans on Aug. 29, 2005, its storm surge broke through levees protecting the city. Water quickly poured into low-lying neighborhoods, flooding houses up to their rooftops and inundating an estimated 80% of the city. People who could not evacuate before the storm and were lucky enough to escape to their roofs were stranded for days in some cases.

Once the water had receded and the death toll counted, it became clear that nearly 1,400 people had died as a result of this devastating storm. The hurricane did more than US$100 billion in damage, equivalent to about $170 billion today when adjusted for inflation.

While there were many unsung heroes during Katrina, the tragic missteps and missed opportunities at all levels of government emergency management are what no emergency manager ever wants to repeat. The response failed in many areas, from broken communications among federal, state and local agencies to the reported horrors in the Superdome as 16,000 evacuees faced failed generators, poor security, dwindling supplies and overflowing toilets.

Three lessons from Katrina stand out today as the Trump administration talks about dismantling the Federal Emergency Management Agency and putting more responsibility for disaster management on local and state agencies.

1. Emergency Response Is Only as Strong as the Weakest Links
FEMA took the brunt of the criticism after Hurricane Katrina. However, serious analyses of what went wrong recognize that good disaster response requires effective governance at all levels.

Before FEMA could spend significant money to deploy people and aid, the state of Louisiana had to request a presidential disaster declaration. However, tensions between the state and federal governments reportedly delayed President George W. Bush’s approval, according to a Senate committee report assessing the response. The committee also found that New Orleans Mayor Ray Nagin’s decision to first issue a voluntary evacuation and not issue a mandatory order until a day before the storm cost precious time.

Once the storm hit, communication and coordination fell apart.
