Storms, floods and disasters in Dunstan
Dunstan isn’t graded for hazard risk: Dunstan is a Census area inside a town, graded with the town.
What Dunstan 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
Hurricanes
Ice storms
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 Dunstan flood? No paid flood claims on record
FEMA’s records show no paid flood insurance claims in Dunstan. That’s not a promise: most homes don’t carry flood insurance, so small floods go unrecorded.
Dunstan isn’t in FEMA’s Community Rating System, which cuts flood insurance up to 45% in towns that do extra flood-proofing.

- Know your evacuation zone and the way off the coast.

- The season runs June through November and peaks from mid-August to mid-October.

- Fill the gas tank and charge phones before the storm arrives.

- Keep sand or salt by the door.
- 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.
