Sorting out insurance claims in Louisiana: coverage disputes, notice handling, and what deserves review first

Fourteen months after the city of New Orleans was obliterated by Hurricane Katrina on August 29, 2005, a federal judge in the Eastern District of Louisiana set the terms for what would become the most consequential American insurance litigation of the twenty-first century. The fundamental question — whether the flooding that destroyed most of New Orleans constituted a covered peril under standard homeowners policies, or whether the storm surge from Katrina's winds was "flood" excluded by virtually every standard homeowners policy — would eventually be answered by the Fifth Circuit Court of Appeals and hundreds of state and federal courts across Louisiana in ways that devastated policyholders and reshaped Louisiana's entire property insurance market. The wind-versus-water dispute produced landmark decisions including Sher v. Lafayette Insurance Co., 570 F.3d 701 (5th Cir. 2009), and In re Katrina Canal Breaches Consolidated Litigation, which addressed thousands of claims from Orleans, Jefferson, and St. Bernard parishes. The anti-concurrent causation clause — a standard policy provision excluding flood damage even when the flood concurs with a covered wind peril — was upheld by Louisiana federal courts as applied to Katrina losses, meaning that policyholders who suffered both wind and flood damage were often unable to collect on the wind portion if the flood simultaneously damaged the same structure. This ruling left thousands of Louisiana policyholders without compensation for losses they believed were covered.

Hurricane Ida made landfall on August 29, 2021 — exactly sixteen years after Katrina — as a Category 4 hurricane with maximum sustained winds of 150 miles per hour, the strongest storm to strike Louisiana since the Last Island Hurricane of 1856. Ida's damage was concentrated in Lafourche, Terrebonne, Jefferson, and St. Charles parishes, with significant damage extending through the New Orleans metropolitan area and north across Lake Pontchartrain into St. Tammany Parish. Unlike Katrina, Ida's primary damage was wind rather than flooding — the strengthened levee system built after Katrina held, and the New Orleans metro area did not experience Katrina-level flooding. But Ida's wind damage — estimated at $55-65 billion in insured losses in Louisiana — triggered a collapse of the Louisiana private property insurance market. More than a dozen Louisiana homeowners insurance companies became insolvent or withdrew from the Louisiana market between 2021 and 2023, unable to pay the volume of Ida claims. The Louisiana Department of Insurance placed multiple carriers into receivership, and thousands of Louisiana homeowners were forced to migrate to the Louisiana Citizens Property Insurance Corporation — the insurer of last resort — as their private carriers failed or left the state.
