How Macon County floods

Flash flooding driven by severe storm systems and heavy rainfall dominates the flood risk profile in Macon County, Alabama, accounting for 13 of the 20 recorded flood events over the last 30 years alongside tropical systems and general floods. Slow-moving storm systems and stalled fronts can produce intense rainfall totals over short periods, such as a February 2022 event that dropped 4 to 6 inches of rain in three hours along the Interstate 85 corridor. Another slow-moving system in February 2024 brought up to 8 inches of rain across parts of Macon, Lee, and Russell counties, resulting in repeated flooding along the same interstate corridor.

National Flood Insurance Program claims data indicates that risk impacts properties across multiple zones. Zone X recorded 3 claims with an average payout of $13,584 and an average recorded water depth of 0 inches. Zone A recorded 1 claim with an average payout of $31,549 and an average recorded water depth of 3 inches. Zone X_UNSHADED recorded 1 claim with an average payout of $10,830 and an average recorded water depth of 1 inch. Homeowners and real estate agents in areas prone to flash flooding, particularly near the Interstate 85 corridor and within designated Zone A, should pay the closest attention to these hazards.

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 Macon County

If a building in Macon 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.
