Local Climate & Risk Factors
New Orleans, Louisiana faces the highest hurricane-related water damage risk of any U.S. state — Hurricanes Katrina (2005), Harvey (2017), and Ida (2021) collectively caused over $200 billion in property damage affecting Louisiana. Much of coastal and metro New Orleans sits below sea level, dependent on a pump system that can fail during storm surge events. Louisiana's high humidity (80–95% average RH during summer months) means any water event produces mold within 24 hours. Standard homeowners policies exclude all flood damage — NFIP coverage is mandatory for properties in SFHA zones, which covers much of south Louisiana. Louisiana Citizens insurance is the insurer of last resort for coastal properties.
Flood-prone areas: Lakeview, Gentilly, New Orleans East, and the Lower Ninth Ward sit in the lowest elevation zones with highest storm surge risk; Garden District and Uptown are higher elevation but still below sea level in many blocks
