How White County floods

Flash flooding from severe thunderstorms dominates the flood profile of White County, accounting for 21 of the 30 recorded flood events over the last 30 years, alongside 9 general flood events. Recent severe weather has frequently driven these conditions, including a widespread severe weather event on May 8, 2024, and two lines of thunderstorms that produced heavy rain and flooding across Putnam and White counties on July 30, 2024.

National Flood Insurance Program records indicate that historical claims are split between moderate- and high-risk areas. Zone X properties recorded 3 claims with an average payout of $23,818 and an average recorded water depth of 50 inches. Zone A properties recorded 2 claims with an average payout of $5,741 and an average recorded water depth of 2 inches.

Homeowners, real estate agents, and journalists should pay the closest attention to properties located in mapped Special Flood Hazard Areas such as Zone A, as well as properties situated in low-to-moderate risk Zone X areas where localized heavy rainfall can produce significant standing water and property damage.

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.
  4. X Outside both lines. No federal requirement to insure, which is not the same as no risk.

Flood insurance in White County

If a building in White 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.
