How Bibb County floods

Flash flooding driven by severe weather and tropical systems dominates the flood history of Bibb County. Over the last 30 years, the NOAA Storm Events Database records 14 flash flood events, alongside 3 tropical storms, 3 general floods, and 2 tropical depressions. Heavy rainfall from regional weather systems and tropical remnants frequently threatens the area, as seen when the remnants of Hurricane Isaac brought heavy rainfall and flash flooding in September 2012, and when Tropical Storm Zeta tracked into Alabama in October 2020.

Federal Emergency Management Agency records show claims concentrated in specific hazard zones. Zone A accounts for 7 claims with an average payout of $2,094 and an average recorded water depth of 1 inch. Zone V includes 3 claims with an average payout of $12,305 and an average recorded water depth of 3 inches. Zone X records 2 claims with an average payout of $0 and an average recorded water depth of 0 inches.

Homeowners, real estate agents, and journalists should pay the closest attention to properties located within Zone A and Zone V, where historical claims and water depths indicate measurable flood risks.

Flash Flood · Dec 25, 2015. A low level boundary across southeast Alabama became the focus for heavy rainfall and severe weather during the early morning hours of December 24th. As the boundary lifted northward, the focus for heavy rainfall and severe weather shifted into north central Alabama.

Flood · Apr 7, 2014. On Sunday, April 6, a low pressure system developed in the northwestern Gulf of Mexico in response to a longwave trough crossing the central United States. The surface low tracked northeastward into Tennessee, bringing a warm front northward across Central Alabama. Warm, moist air rode over the warm front, leading to development of a large rain shield to the north of the frontal boundary. This rain slowly spread n…

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.
  3. X shaded The 0.2% (500-year) floodplain, plus some levee-protected and very shallow flood areas.

Flood insurance in Bibb County

If a building in Bibb 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.
