What stands out about Yosemite West’s weather risks
Read from FEMA’s records below. The page puts what stands out first.
Does Yosemite West flood? No paid flood claims on record
FEMA’s records show no paid flood insurance claims in Yosemite West. That’s not a promise: most homes don’t carry flood insurance, so small floods go unrecorded.
How exposed is Yosemite West?
FEMA expects yearly storm and flood damage to homes and buildings here to be higher than in 94% of U.S. communities, mostly from wildfires and inland flooding.
Rated higher than 1,116 of the 1,619 California towns we cover.
Yosemite West is smaller than a census tract, so it shares the figures of the tract around its center.

Get ready for what Yosemite West actually faces
A short kit for its top hazards, what to check before you buy, and where neighbors get alerts.
- Clear dead leaves and brush within 5 feet of the house.
- Sign up for local alerts and know two ways out.
- Keep N95 masks for smoky days.
- 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.
- Know the nearest cooling center or air-conditioned library.
- Drink water before you feel thirsty.
- Check on neighbors who live alone.
- 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 Mariposa County’s 21 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 Yosemite West’s own flood-insurance community; household aid to the registrant’s city; repair grants to Yosemite West.
- 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.
