St. Charles Parish west of New Orleans is home to Waterford Nuclear Plant and sits in one of the most hurricane-vulnerable locations in Louisiana. The parish is almost entirely below sea level protected by levees on the Mississippi River. Hurricane Ida in 2021 made landfall nearby causing catastrophic damage across the parish. The parish also hosts major petrochemical facilities along the Mississippi River creating compound industrial and nuclear emergency planning requirements.

  • Store at least 72 hours of food and water.
