How Madison County floods

Standard river flooding and flash flooding from summer storms define the primary flood hazards in Madison County, with the NOAA Storm Events Database recording 45 flood events and 23 flash flood events over the last 30 years. Slow-moving storm systems frequently produce heavy rainfall exceeding 6 inches. For example, a complex of storms on July 17, 2022, caused widespread flooding and pockets of flash flooding across Madison and Delaware counties. Similarly, slow-moving thunderstorms pushed across central Madison County on July 5, 2019, resulting in observed flash flooding in a northern Anderson suburb.

National Flood Insurance Program claims data show that properties in high-risk Zone A have experienced the highest volume of claims at 203, with an average payout of $13,405 and an average recorded water depth of 6 inches. However, properties outside designated high-risk zones also sustain damage; Zone X_UNSHADED properties recorded 41 claims with an average payout of $23,343 and an average water depth of 2 inches, while Zone X properties logged 26 claims averaging $27,753 with an average water depth of 3 inches. Homeowners and real estate professionals in Zone A and Zone X variants should pay close attention to these localized flood risks.

From the storm reports

Flood · Jun 14, 2025. Multiple rounds of slow-moving storms impacted much of north central Indiana during the late overnight and morning hours of June 14th with rain totals as high as 6 inches. Numerous roads were closed with the most severe flooding noted on the south side of Kokomo. This flooding led to minor flooding along the Wildcat creek basin and the upper Wabash and upper White rivers.

Flash Flood · Jul 17, 2022. A complex of storms moved over portions of Madison and Delaware county causing widespread flooding and pockets of flash flooding. The rain fell over the course of several hours with amounts of over 6 inches in spots. Conditions had been fairly dry in the days leading up which limited the extent of flash flooding.

Flood · Jul 8, 2020. During the afternoon hours, a series of thunderstorms moved across north central Indiana. A few of these storms became severe and produced isolated wind damage to portions of Howard and Tipton counties. Most storms remained sub-severe and had limited impacts.

Flash Flood · Jul 5, 2019. A band of very slow moving thunderstorms pushed east-southeast across central portions of Madison County during the afternoon of July the 5th. Flash flooding was observed in a northern Anderson suburb.

The zones you’ll see on the map

Flood insurance in Madison County

If a building in Madison 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.
