Franklin sits in the Harpeth River corridor, which flooded catastrophically during the May 2010 Tennessee event — 13 to 20 inches of rain in 48 hours. Flash flood events in 2021 and 2023 struck Franklin neighborhoods with little warning. Clay-heavy Williamson County soils absorb rainfall slowly, so the next storm can push water inside within minutes.
The most common losses are storm drainage overwhelm and burst supply lines discharging 100 gallons before shut-off. July average relative humidity exceeds 75%, extending drying timelines to five to seven days. Properties in FEMA Zones A and AE along the Harpeth require flood insurance — standard policies exclude rising water. Delayed drying guarantees secondary mold damage.
