How Jackson County floods

River and general flooding dominate the historical record in Jackson County, Indiana, accounting for 103 events and 3 deaths compared to 30 flash flood events over the last 30 years.

Severe weather patterns are documented in recent historical narratives, such as a heavy rain event from January 9th through the 11th, 2020, which brought 3 to 5 inches of rainfall to the area. Another multi-day system brought severe weather and flooding from June 15th through the 17th, 2019, driven by a stalled front and repeated rounds of heavy rain.

National Flood Insurance Program records indicate that policyholders in multiple zones experience significant impacts. Zone A recorded 61 claims with an average payout of $11,032 and an average recorded water depth of 9 inches. Meanwhile, Zone X properties experienced 15 claims with an average payout of $23,854 and an average recorded water depth of 20 inches, and Zone X unshaded properties saw 12 claims with an average payout of $22,552 and an average recorded water depth of 11 inches. Homeowners and real estate professionals working in both designated high-risk Special Flood Hazard Areas and moderate-to-low risk Zone X areas should pay close attention to these historical payout and water depth patterns.

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.

  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.
