How Upson County floods

Flash flooding from severe weather events dominates the flood risk profile in Upson County, Georgia, based on historical storm event data. Over the last 30 years, the NOAA Storm Events Database recorded 24 flash flood events, 14 tropical storm events, 13 general flood events, and 3 hurricane events.

This risk is exemplified by severe weather in March 2023, when a prolonged active weather pattern brought extreme rainfall to the region, dropping a swath of 4 or more inches of rain—with isolated amounts exceeding 10 inches—that resulted in widespread flash flooding across the state on March 26 and March 27.

Federal insurance claims data reflects differing impacts across flood zones. Properties located in FEMA Zone A experienced the highest frequency of National Flood Insurance Program claims with 19 filings, averaging a payout of $15,389 and an average recorded water depth of 7 inches. Zone X recorded 4 claims with an average payout of $13,947 and an average recorded water depth of 78 inches, while Zone UNKNOWN recorded 3 claims with an average payout of $13,285 and an average recorded water depth of 2 inches. Homeowners and real estate agents managing properties in Zone A and Zone X should pay the closest attention to these historical flood and water depth patterns.

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.

Cross-section of a river floodplainDiagram: a river valley. The floodway is the channel and the land beside it; the 1%-annual-chance flood surface (the base flood elevation) covers the valley floor as zone A or AE; a narrow band higher up is shaded X, the 0.2% floodplain; higher ground is X.0.2% CHANCE A YEAR (500-YEAR)BASE FLOOD ELEVATION · 1% A YEARXAEFloodwayAEX
  1. A / AE Inside the 1%-a-year floodplain: about a 26% chance of flooding over a 30-year mortgage. AE has a mapped base flood elevation; plain A does not.
  2. Floodway The channel and the land beside it that has to be kept clear enough to carry the flood. Building here is tightly limited.

Flood insurance in Upson County

If a building in Upson 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.
