Savannah’s water damage stems from its low, tidal coastal setting and its irreplaceable historic homes — a combination of frequent flooding, hurricane surge, and old materials that don’t dry easily.
- Tidal and ‘sunny-day’ flooding affect the low-lying Historic District and downtown.
- Hurricanes and tropical systems (like Matthew) bring surge and torrential rain.
- Centuries-old homes hold moisture and are slow to dry in the Lowcountry humidity.
In this guide:
Tidal flooding and storms
Savannah sits just above sea level along the tidal Savannah River, so high tides and storm surge push water into the Historic District and low neighborhoods, sometimes on clear days. Hurricanes add torrential rain and surge. Coastal flood water is contaminated, which shapes the cleanup — the Georgia Water Damage Resource Guide covers categories and recovery.

Historic homes and humidity
Savannah’s famous historic homes, with their age and below-grade spaces, hold moisture and dry slowly, and the Lowcountry humidity keeps mold active year-round. Repeated tidal wetting is especially hard on old materials. The mold growth timeline explains why prompt drying matters.
The bottom line
In Savannah, plan for tidal flooding and slow-drying historic materials. Treat coastal water as contaminated, dry thoroughly and quickly, and don’t let the humidity get a head start on mold.
Frequently asked questions
Why does Savannah flood?
Savannah sits just above sea level along the tidal Savannah River, so high tides and storm surge push water into the low-lying Historic District and downtown, sometimes on clear days. Hurricanes add surge and heavy rain.
Why are Savannah’s historic homes at higher risk?
Their age, below-grade spaces, and original materials make them slow to dry and prone to rot, while repeated tidal wetting and Lowcountry humidity keep moisture and mold active.
Is coastal flood water in Savannah safe to clean up?
No. Tidal and flood water is contaminated and salty; it should be handled as contaminated, with affected porous materials removed and the area dried and sanitized.
