How Scott County floods

River flooding and general floods, alongside flash floods, define the flood character of Scott County, with NOAA records detailing 59 flood events and 22 flash flood events over the last 30 years. Heavy rainfall and severe weather outbreaks produce significant hazards across the region, as demonstrated on May 26, 2024, when a shortwave trough and bowing storm line moved across southeast Missouri. Additionally, above-normal April rainfall led to elevated river levels on the Mississippi River, extending minor flood conditions at Chester and Cape Girardeau through the first three weeks of May 2024.

National Flood Insurance Program records show that flood losses concentrate heavily in high-risk areas. Zone A properties experienced the vast majority of claims with 408 filings, averaging a payout of $13,148 and an average recorded water depth of 9 inches. Properties located in moderate-to-low risk zones, including Zone X_SHADED, Zone UNKNOWN, Zone X, and Zone X_UNSHADED, recorded fewer claims—ranging from 10 to 26 claims—with average payouts between $5,410 and $11,176, and average recorded water depths of 2 to 3 inches. Homeowners and real estate agents with properties in Zone A should pay the most attention to flood risk given the higher frequency and severity of past claims in this zone.

Where the flood claims came from

8% of Scott County’s flood insurance claims were on properties rated outside FEMA’s high-risk zones.

From the storm reports

Flood · Feb 15, 2025. Showers and thunderstorms produced heavy rainfall (2-5) as they streamed northeast across southeast Missouri in the afternoon and evening of the 15th. The greatest rainfall amounts were near the Mississippi River in New Madrid and Mississippi counties. Minor flooding of city streets occurred in the city of New Madrid and along numerous state highways and county Roads. The heavy rain caused a retaining wall to coll…

Flood · May 26, 2024. The second major severe weather outbreak for the month occurred on the 26th for the Quad State region. On the synoptic scale, a shortwave trough centered in the middle of the country with a 60 kt mid-level jet moved across northern Arkansas. A weak surface low was moving into SE Missouri during the morning with a secondary low located further northwest. A warm frontal boundary was draped across our area. A bowing…

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.

Flood insurance in Scott County

If a building in Scott 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.
