During the late evening of October 28th through the morning of October 29th, Tropical Storm Zeta swept rapidly across north Georgia producing widespread wind damage and isolated flooding across north and portions of central Georgia.

Hurricane Michael made landfall along the Florida panhandle at Mexico beach (just southeast of Panama City) on the afternoon of October 10, 2018 as a high-end Category 4 hurricane (max winds of 155 MPH). Michael then moved rapidly inland, causing widespread wind damage along its path as it swept northeast across south and central Georgia.

Every colour on the map above is a place on this drawing: where the ground sits relative to the flood FEMA plans for.
If a building in Chattahoochee County is in a high-risk zone (A or V) and its mortgage comes from a federally regulated or insured lender, or is federally backed, flood insurance is required.
Outside those zones it is optional, and often worth having: from 2014 to 2024 nearly one-third of NFIP claims came from outside the high-risk Special Flood Hazard Area. Since Risk Rating 2.0, NFIP premiums are set for each building, so the only reliable price is a quote: FloodSmart.gov or a local agent.
