Potsdam is calmer than 83% of U.S. communities
Most of the natural-hazard damage FEMA expects in Potsdam comes from inland flooding, and overall the risk is very low for a U.S. community.
What stands out about Potsdam’s weather risks
Read from FEMA’s records below. The page puts what stands out first.
How exposed is Potsdam?
FEMA expects yearly storm and flood damage to homes and buildings here to be higher than in 17% of U.S. communities, mostly from inland flooding and tornadoes.
Calmer than 1,914 of the 2,573 Ohio towns we cover.
Potsdam is smaller than a census tract, so it shares the figures of the tract around its center.
Does Potsdam flood? No paid flood claims on record
FEMA’s records show no paid flood insurance claims in Potsdam. That’s not a promise: most homes don’t carry flood insurance, so small floods go unrecorded.
Potsdam 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 Potsdam 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.
- Pick your spot now: the lowest floor, an inside room, no windows.
- A watch means be ready; a warning means take cover now.
- Keep shoes and a flashlight by the bed.
- Drop, cover and hold on.
- Strap tall furniture and the water heater to the wall.
- Know how to shut off the gas.
- 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.
Most disasters here begin in December–February
The month each of Miami County’s 12 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 Potsdam’s own flood-insurance community; household aid to the registrant’s city; repair grants to the Village of Potsdam.
- 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.
