Summit’s biggest natural hazard is inland flooding
Most of the natural-hazard damage FEMA expects in Summit comes from inland flooding, and overall the risk is high for a U.S. community.
What stands out about Summit’s weather risks
Read from FEMA’s records below. The page puts what stands out first.
Does Summit flood? No paid flood claims on record
FEMA’s records show no paid flood insurance claims in Summit. That’s not a promise: most homes don’t carry flood insurance, so small floods go unrecorded.
Summit isn’t in FEMA’s Community Rating System, which cuts flood insurance up to 45% in towns that do extra flood-proofing.
Insurance rates: Benton County.How exposed is Summit?
FEMA expects yearly storm and flood damage to homes and buildings here to be higher than in 72% of U.S. communities, mostly from inland flooding and earthquakes.
Calmer than 241 of the 425 Oregon towns we cover.
Summit is smaller than a census tract, so it shares the figures of the tract around its center.

Get ready for what Summit 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.
- Drop, cover and hold on.
- Strap tall furniture and the water heater to the wall.
- Know how to shut off the gas.
- Watch for new cracks, tilting trees or suddenly muddy streams after heavy rain.
- Stay off steep slopes in a downpour.
- Leave if you hear rumbling upslope.
- 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.

Most disasters here begin in December–February
The month each of Benton County’s 13 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 Summit’s own flood-insurance community; household aid to the registrant’s city; repair grants to Summit.
- 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.
