What Happened
Katrina made landfall as a Category 3 hurricane with Category 5 storm surge. The catastrophic failure of the New Orleans levee system — not the storm itself — caused most damage. 80% of New Orleans flooded, with some areas under 15+ feet of water for weeks. The storm exposed critical gaps in flood insurance coverage and FEMA disaster response.
Rainfall Record
10–15 inches; catastrophic damage primarily from storm surge and levee failures, not rainfall

Key Lessons for Homeowners
- 1
Levee failure is not 'flooding' under some policy definitions — thousands of claims were disputed on this basis
- 2
FEMA's initial response was widely criticized — have a 72-hour self-sufficiency plan
- 3
NFIP's $250,000 building limit is insufficient for mid-range New Orleans homes valued $300K–$700K
- 4
Extended flooding (weeks vs days) causes exponentially greater structural damage — longer flooded = higher cost
