Flash Flood · Sep 10, 2013. Multiple thunderstorms moved over portions of the upper St Marys River valley on the night of the 9th. Most of the heavy rain fell on the Canadian side of the border, but the swath of excessive rain did cross the north half of Sugar Island.

Flood · Sep 24, 2010. Two days of heavy rain produced localized flooding in Eastern Upper Michigan. Rainfall amounts of 2 to 5 inches were common, most of which fell on the night of the 23rd. Raber picked up 4.75 inches of rain, Cedarville 4.10 inches, and St Ignace 3.40 inches.

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.

  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 Chippewa County

If a building in Chippewa 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.
