What stands out about Big Bay’s weather risks
Read from FEMA’s records below. The page puts what stands out first.
How exposed is Big Bay?
FEMA expects yearly storm and flood damage to homes and buildings here to be higher than in 26% of U.S. communities, mostly from inland flooding and cold waves.
Rated higher than 965 of the 1,771 Michigan towns we cover.
Big Bay is smaller than a census tract, so it shares the figures of the tract around its center.

Does Big Bay flood? No paid flood claims on record
FEMA’s records show no paid flood insurance claims in Big Bay. That’s not a promise: most homes don’t carry flood insurance, so small floods go unrecorded.
Big Bay isn’t in FEMA’s Community Rating System, which cuts flood insurance up to 45% in towns that do extra flood-proofing.

Get ready for what Big Bay actually faces
A short kit for its top hazards, what to check before you buy, and where neighbors get alerts.
- Turn around at flooded roads: a foot of moving water can carry off a car.
- Flood insurance usually takes 30 days to start, so buy it before the forecast.
- Keep papers and medicines up high, in a grab-and-go bag.
- Let faucets drip so pipes don’t freeze.
- Know where your water shutoff is.
- Never heat the house with the oven or a grill.
- Park in a garage or under cover when storms are forecast.
- Stay away from windows while it falls.
- Photograph roof and car damage for your insurer.
- Look up the address on FEMA’s flood map.
- Ask the seller or landlord whether it has ever flooded, and what flood insurance costs there.
- Get a flood insurance quote early: policies usually start 30 days after you buy.
Know where neighbors sign up for alerts? Add it to the Handbook so everyone has it.

The month each of Marquette County’s 9 declared disasters began, since 1953.
What these numbers can and can’t tell you
- An average, not a forecast. FEMA’s National Risk Index estimates the damage 18 kinds of natural hazards cause in a typical year, from decades of records and models. A quiet decade can follow a bad year.
- Compared by rate. “Higher than N%” compares yearly damage as a share of what’s there, so a big city isn’t rated riskier just for having more buildings.
- Money that reached town. Flood claims are matched to Big Bay’s own flood-insurance community; household aid to the registrant’s city; repair grants to Big Bay.
- It follows property value. FEMA’s model weighs damage to buildings, so a place that recently lost many homes can rate lower than it feels.
