From the storm reports

Flash Flood · Jun 3, 2024. On Sunday evening June 2 and into Monday June 3, a round of strong storms developed across eastern SD and southwestern MN along a stationary boundary. These storms produced a brief tornado in Renville County, wind damage in Morrison County, and small hail in Stevens County. There were also 3 to 4 inches of heavy rain in central Minnesota, with flooding reported in Todd and Sibley Counties.

Flash Flood · May 31, 2014. Several rounds of torrential rainfall that developed across west central Minnesota, and moved northeast across the same areas of portions of central Minnesota, caused county roads to flood, some of which had damage due to the fast moving water across the asphalt roads. One round of storms produced flooding near Sauk Centre, and another round later in the day caused more flooding in northwest Stearns and southern T…

Flash Flood · Jun 21, 2013. Several rounds of thunderstorms developed Thursday late afternoon and evening, June 20th, mostly in west central Minnesota, and moved eastward. These storms produced some penny to quarter size hail, but the main event was damaging straight line winds and torrential rainfall during the late evening and overnight period. These storms moved across central and east central Minnesota after midnight, with some redevelop…

Flood · Mar 23, 2009. A strong area of low pressure moved northward across the upper midwest and combined with unseasonable early Spring gulf moisture to cause a large area of heavy rainfall. Local rainfall totals were in the two to three inch range before the system moved north of the region. Along with the heavy rainfall, and due to thick ice remaining on areal streams, creeks and rivers, ice jams developed and caused flooding of are…

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 Todd County

If a building in Todd 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.
