Captree isn’t graded for hazard risk: Captree has 282 residents; we grade towns of 1,000 or more.
What Captree faces
Each hazard’s share of the building damage FEMA expects here, and how its rate compares with the rest of the country.
Coastal flooding
River and rain flooding
Shares are of FEMA’s expected building damage, the measure the grade uses; ranks compare each hazard’s building-damage rate with all 85,154 U.S. census tracts. In FEMA’s terms, river and rain flooding is FEMA’s “Inland Flooding” (rivers and streams overflowing their banks, or rain overwhelming drainage). FEMA defines coastal flooding as high or rising tides and storm surge, so surge damage is counted there. Drought isn’t listed: FEMA counts its losses in crops only.
Does Captree flood? No paid flood claims on record
FEMA’s records show no paid flood insurance claims in Captree. That’s not a promise: most homes don’t carry flood insurance, so small floods go unrecorded.
Captree isn’t in FEMA’s Community Rating System, which cuts flood insurance up to 45% in towns that do extra flood-proofing.
Insurance rates: Suffolk County.The storms Captree remembers
None of the 26 disasters declared for Suffolk County shows FEMA aid or repair money reaching Captree itself in FEMA’s records, so these are its biggest flood-claim years.
Suffolk County has had 26 natural disasters declared by the President since 1953, most often severe storms, then hurricanes and tropical storms. Not counted: the 2005 Hurricane Katrina evacuee emergency, which covered counties that took in evacuees; the 2001 World Trade Center declarations.

Get ready for what Captree faces
A short kit for the hazards that drive the building damage here, 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.
- 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.
