From the storm reports

Flood · Jul 29, 2024. Unusually moist airmass ahead of an approaching mesolow and lake breezes led to development of efficient rain-producing showers and storms in the late afternoon...leading to rainfall rates near two and a half inches per hour at times. Storm total rainfall by the next morning was largely between 1 and locally as high as 4-6 inches.

Flash Flood · Aug 11, 2021. After a warm front mixed northward across northern Michigan during the day, a weak shortwave progressing overhead helped initiate storms along a weak boundary over Lake Michigan. This line of storms tracked eastward across the area, producing damaging winds into the early morning hours of 8-11. Training storms across parts of NW lower Michigan also produced heavy rainfall and flash flooding in multiple locations,…

Flash Flood · Jul 5, 1999. Numerous thunderstorms moved across eastern upper and northwest lower Michigan with isolated severe wind reports. Training echoes (thunderstorms continuously moving over the same general area) over the Lake Michigan shoreline counties in northwest lower Michigan caused up to 4 inches of rainfall within a few hours. This caused many secondary roadways near the Grand Traverse Bay area and across the Leelanau peninsu…

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.

  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 Antrim County

If a building in Antrim 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.
