How Vermillion County floods

Standard riverine floods dominate the historical record in Vermillion County, accounting for 105 out of 126 recorded flood events over the last 30 years, alongside 21 flash flood events.

Severe weather and heavy rainfall drive these occurrences, as demonstrated by storms on July 5, 2018, when heavy rainfall caused flooding along Interstate 74, and earlier events from June 7 to 8, 2015, when 2 to nearly 6 inches of rain triggered flooding across Vermillion, Warren, and Fountain counties.

Property owners in FEMA-designated Zone A face the highest frequency of risk, recording 43 National Flood Insurance Program claims with an average water depth of 18 inches and an average payout of $7,710. Additionally, properties with unknown flood zones have accounted for 21 claims averaging 6 inches of recorded water depth, while Zone X properties, though recording only 3 claims, experienced severe inundation averaging 69 inches of recorded water depth and an average payout of $27,878. Homeowners, real estate agents, and journalists should pay the closest attention to properties located within Zone A, unmapped or unknown zones, and Zone X locations susceptible to deep inundation.

Flash Flood · Jun 4, 2020. During the evening hours of June 3rd a series of thunderstorms brought pockets of severe weather to portions of central Indiana. A few thunderstorms became severe north of the Indianapolis metro which led to thunderstorm wind damage. A microburst from another thunderstorm caused fairly significant damage in Rush County near the county seat of Rushville. Thunderstorms continued into the night with flash flooding…

Flood · Feb 22, 2018. Unseasonably high amounts of moisture flowed into central Indiana from the southwest and south during the latter part of February. At times during the period of February 19th to the 24th, the precipitable water values (a measure of moisture in the atmosphere) reached record levels for February.||Heavy rainfall fell early in the week (February 19/20) across northern sections of central Indiana. The second round of…

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.

Flood insurance in Vermillion County

If a building in Vermillion 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.
