What stands out about Ko Vaya’s weather risks
Read from FEMA’s records below. The page puts what stands out first.
Does Ko Vaya flood? No paid flood claims on record
FEMA’s records show no paid flood insurance claims in Ko Vaya. That’s not a promise: most homes don’t carry flood insurance, so small floods go unrecorded.
Ko Vaya isn’t in FEMA’s Community Rating System, which cuts flood insurance up to 45% in towns that do extra flood-proofing.
Insurance rates: Pima County.How exposed is Ko Vaya?

Rated higher than 291 of the 467 Arizona towns we cover.

Get ready for what Ko Vaya 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.
- Know the nearest cooling center or air-conditioned library.
- Drink water before you feel thirsty.
- Check on neighbors who live alone.
- Keep a shovel, a blanket and snacks in the car.
- Clear snow from furnace and dryer vents.
- Check on older neighbors when the power goes out.
- 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 June–August
The month each of Pima County’s 11 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 Ko Vaya’s own flood-insurance community; household aid to the registrant’s city; repair grants to Ko Vaya.
- 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.
