Jacksonville's relative humidity averages above 75%, and subtropical heat means wet structural materials begin supporting mold within 24 hours of saturation. The St. Johns River floods from both Atlantic storm surge and upstream rainfall simultaneously. Hurricane Irma in 2017 set a record St. Johns crest of 5.2 feet, inundating San Marco, Riverside, and Ortega.
FEMA Zone AE covers large portions of Jacksonville — the Northside near Trout River, the Westside along the Ortega and Cedar Rivers, and the Beaches communities. Category 3 contamination is more common here than in most inland cities due to tidal flooding and aging sewer infrastructure.
