How Jackson County floods

Flash flooding driven by severe storm systems and tropical systems dominates the flood character of Jackson County. Over the past 30 years, the NOAA Storm Events Database records 16 flash flood events, 13 tropical storm events, 2 hurricanes, and 1 general flood event.

Recent occurrences illustrate these tropical impacts. In September 2020, a weakening Tropical Storm Sally moved into Georgia, spreading heavy rainfall amounts of 2 to 8 inches and producing flash flooding. Similarly, in October 2020, the remnants of Hurricane Delta passed northwest of the state, bringing Gulf moisture that caused pockets of heavy rainfall and flooding across northeast Georgia.

National Flood Insurance Program records show varying impacts across zones. Properties in Zone X recorded 6 claims with an average payout of $5,799 and an average recorded water depth of 1 inch. Zone A recorded 1 claim with an average payout of $42,529 and an average recorded water depth of 0 inches. Homeowners and real estate agents should pay particular attention to properties located in mapped flood hazards such as Zone A, as well as those vulnerable to intense rainfall and flash flooding in Zone X.

From the storm reports

Tropical Storm · Oct 29, 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.

Flash Flood · Sep 17, 2020. A weakening Tropical Storm Sally moved into Georgia on September 16th, spreading heavy rainfall amounts and producing damaging winds in north and central Georgia. Rainfall amounts of 2 to 8 inches occurred, with the axis of heaviest rainfall extending from near Columbus, to Macon, to Augusta. The highest winds were observed in the metro Atlanta area as Sally's convective bands moved through late on September 16th.

Flash Flood · Oct 10, 2020. During the afternoon and evening of October 10th, as the remnants of Hurricane Delta passed northwest of Georgia, moisture from the Gulf of Mexico spread across the area. Several weak tornadoes occurred in north and central Georgia in addition to pockets of heavy rainfall and flooding across the Atlanta metropolitan area and portions of northeast Georgia.

Flash Flood · Apr 19, 2019. Another in a series of deep upper-level troughs and its associated surface low and cold front moved through the region. Marginal instability but moderate to high shear and strong dynamics resulted in a line of strong thunderstorms, with isolated damaging winds and a few tornadoes, that swept through north and central Georgia during the morning. Training storms and ample moisture produced a swath of heavy rain stre…

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 Jackson County

If a building in Jackson 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.
