From the storm reports

Flash Flood · Aug 22, 2014. A weak upper level system dropped southeast across the region. A stationary boundary extended west to east across the area. Three rounds of thunderstorms developed either across the area or upstream in Illinois and tracked southeast along the front. Precipitable water exceeded 2 inches allowing for a very moist atmosphere and efficient rain producing thunderstorms. The first round produced isolated severe weather…

Flood · Feb 28, 2011. Numerous showers and thunderstorms developed and moved across portions of Northern Indiana. One to three inches of rain fell across the area with localized higher amounts. This resulted in some roads becoming impassable due to flood waters. The event continued into March when a few rivers went over their banks.

Flash Flood · May 14, 2011. A weak surface trough and low pressure system tracking along it allowed for thunderstorms to develop across portions of northeastern Indiana. Weak flow parallel to the trough and redevelopment of thunderstorms produced rainfall rates of one to two inches per hour. This caused areas of flooding and flash flooding. No injuries were reported.

Flash Flood · Aug 5, 1998. Synoptic and Mesoscale conditions for August 5th...A large upper trough was anchored over the central plains the morning of August 4th with a surface reflection across southeastern Iowa. A warm front stretched from this low across northern Indiana which provided the low level focus for shower and thunderstorm development the morning of the 4th. The airmass south of this front was tropical in nature with surface…

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 Blackford County

If a building in Blackford 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.
