Georgia faces flood risk from Atlantic coastal storm surge, riverine flooding along the Savannah, Chattahoochee, and Flint rivers, and increasing urban flash flooding in the Atlanta metro. Hurricane Matthew in 2016 caused severe flooding in southeast Georgia with the Savannah River reaching its highest level in over 80 years and causing $100 million in damage. Hurricane Irma in 2017 brought widespread flooding across the state. The Atlanta metro has experienced rapid urbanization that has dramatically increased flash flood risk with major events in 2009, 2017, and 2021 causing hundreds of millions in damage. The Chattahoochee River regularly floods its valley through Cobb, Fulton, and Muscogee counties. Valdosta and Lowndes County in south Georgia face chronic flooding along the Withlacoochee River. Augusta and Richmond County experience significant flood risk along the Savannah River. The state has over 600 NFIP-participating communities and has received over $1 billion in FEMA flood-related disaster declarations since 2000. Georgia's coastal plain has extensive wetlands and tidal marshes that provide natural flood buffering, but development pressure threatens these critical buffers.

Frequently Asked Questions — Georgia
Does Atlanta flood?
Yes. Metro Atlanta has experienced significant flooding events including major damage in 2009 and 2021. Urbanization has increased impervious surfaces, overwhelming stormwater systems during heavy rain.
How bad is coastal flooding in Georgia?
Georgia's coast faces serious storm surge risk. Hurricane Matthew produced Savannah River flooding not seen in 80+ years. Sea level rise is increasing tidal flooding frequency along the barrier islands.
Do I need flood insurance in Georgia?
If you are in a designated flood zone with a federally backed mortgage, yes. Even outside high-risk zones, metro Atlanta alone has experienced hundreds of millions in flood damage over the past two decades.
