How Saline County floods

Long-term NOAA data indicates that standard river and creek flooding dominates Saline County, accounting for 120 recorded events over the last 30 years alongside 29 flash flood events.

Historical events illustrate these risks across the region. Heavy late-winter and spring precipitation combined with snowpack to cause prolonged Missouri River flooding that persisted from March through June 2019. Additionally, torrential rains from thunderstorms in May 2019 caused widespread areas of flooding. FEMA insurance claims data reflects this hazard distribution, showing that Zone A properties experienced 13 claims with an average payout of $23,518 and an average recorded water depth of 8 inches. Unshaded Zone X properties recorded 2 claims with an average payout of $6,853 and an average recorded water depth of 1 inch.

Properties located within FEMA Zone A and near the Missouri River or local waterways should pay the closest attention to flood risk, as these areas experience the highest frequency of claims and the greatest average water depths during flood events.

In flood insurance claims here that reported a flood depth, the average was 7 inches.

From the storm reports

Flash Flood · Jun 25, 2021. Late in the afternoon, and through the evening hours on June 24 a cluster of storms over southeast Nebraska congealed into a line of thunderstorms that focused across northern Missouri. Most notably within this line of storms was a cluster of QLCS tornadoes that formed in Grundy County. There may have been other tornadoes associated with circulations that were noted on radar, but emergency management confirmed dam…

Flood · May 21, 2019. A line of generally sub-severe thunderstorms moved through the region during the early morning hours on May 21. These storms didn't produce any severe winds or hail, but as they moved east wake low winds produced damage consisting of several tree limbs down as well as power lines and power poles. The storms then went on to produce torrential rains which caused areas of flooding.

Flood · May 1, 2019. Heavy late winter and spring precipitation, mixed with a loaded snow pack caused the Missouri River to flood in March. Consistent heavy rains continued the Missouri River flooding into and through May. Some locations along the Missouri River were in major flood for several weeks as heavy rains continued.

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 Saline County

If a building in Saline 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.
