How Monroe County floods

Monroe County experiences flood risk driven primarily by tropical systems and heavy rainfall, with the NOAA Storm Events Database recording 14 tropical storms, 7 floods, 6 flash floods, and 3 hurricanes over the last 30 years. Extreme rainfall events can rapidly overwhelm local drainage and cause significant flash flooding, as demonstrated by storms in March 2023 and October 2021 that dropped localized rainfall totals ranging from 4 to over 10 inches across the region, including areas near Forsyth.

Federal insurance claims data indicates that property risk extends across multiple zones. Properties in Zone A have accounted for 49 claims with an average payout of $66,322 and an average recorded water depth of 24 inches. Meanwhile, properties in Zone X have experienced 11 claims with an average payout of $31,443 and an average recorded water depth of 8 inches, while one claim in an unknown zone recorded a $51,600 payout with 0 inches of average recorded water depth.

Homeowners and real estate agents with properties located within Zone A should pay the closest attention to flood risk, given the significantly higher average payouts and water depths associated with these areas, though properties in Zone X also face documented flood exposure.

Where the flood claims came from

Less than 1% of Monroe County’s flood insurance claims were on properties rated outside FEMA’s high-risk zones.

From the storm reports

Flash Flood · Mar 27, 2023. A prolonged, active weather pattern persisted across Georgia through late March, culminating in a series of disturbances that impacted the region March 25th through March 28th. In addition to numerous reports of damaging winds, hail and a few tornadoes, extreme rainfall amounts caused flash flooding over portions of the state. A swath of 4 or more inches of rain stretched from LaGrange, to Forsyth, to Augusta, wit…

Flash Flood · Oct 6, 2021. A very moist and marginally unstable airmass ahead of a deep upper-level low over the lower Mississippi Valley resulted one report of a tree down and several flash flooding reports over middle Georgia. Heavy rainfall amounts of 1.5 to 3 inches were observed along a line from Thomaston to Gray to Eatonton to Comer, with pockets of higher amounts between 4 and 8 inches.

Tropical Storm · Oct 28, 2020. 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. Around 1.5 million customers lost electricity for some period of time, some for several days.

The zones you’ll see on the map

Every colour on the map above is a place on this drawing: where the ground sits relative to the flood FEMA plans for.

Flood insurance in Monroe County

If a building in Monroe 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.
