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

Rated higher than 1,339 of the 1,771 Michigan towns we cover.
Harvey is smaller than a census tract, so it shares the figures of the tract around its center.

Get ready for what Harvey actually faces
A short kit for its top hazards, what to check before you buy, and where neighbors get alerts.
- Let faucets drip so pipes don’t freeze.
- Know where your water shutoff is.
- Never heat the house with the oven or a grill.
- 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.
- 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 Harvey’s own flood-insurance community; household aid to the registrant’s city; repair grants to Harvey.
- 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.
