What Oak Beach faces
Each hazard’s share of the damage FEMA expects here, and how it compares with the rest of the country.

Inland flooding
How exposed is Oak Beach?
FEMA expects yearly storm and flood damage to homes and buildings here to be higher than in 77% of U.S. communities, mostly from coastal flooding and inland flooding.
Rated higher than 1,421 of the 1,524 New York towns we cover.
Oak Beach is smaller than a census tract, so it shares the figures of the tract around its center.
Does Oak Beach flood? No paid flood claims on record
FEMA’s records show no paid flood insurance claims in Oak Beach. That’s not a promise: most homes don’t carry flood insurance, so small floods go unrecorded.
Oak Beach 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 Oak Beach actually faces
A short kit for its top hazards, what to check before you buy, and where neighbors get alerts.
- Know your evacuation zone and the way off the coast.
- Storm surge comes fast: leave when you’re told, not when the water arrives.
- Move cars to high ground before king tides and nor’easters.
- 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.
- 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.

The month each of Suffolk County’s 28 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 Oak Beach’s own flood-insurance community; household aid to the registrant’s city; repair grants to Oak Beach.
- 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.
