Large portions of New Orleans sit 1–6 feet BELOW sea level, protected by 350 miles of levees; the 2005 Katrina levee failure inundated 80% of the city; Lake Pontchartrain to the north and the Mississippi River to the south create dual flood threats; year-round 90%+ humidity drives constant mold pressure requiring professional dehumidification after any water event
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
