What it means for a buyer or owner
In Martin County, hurricane wind and storm surge tend to arrive together, and the county has taken 6 direct hurricane landfalls. Wind is the part every property shares, so the roof and openings matter as much as the flood zone.
Ask for the roof's age and permit, any shutters or impact-rated windows, and a wind mitigation report.

Inland flooding
Relatively ModerateThe local numbers
- FEMA rates inland flooding risk in Martin County "Relatively Moderate" (score 83.3 of 100, compared with every U.S. county).1
- Expected damage to buildings: about $18.2 million a year, the 31st-highest expected building loss from this hazard of 67 counties in the state.1
- FEMA's index maps about 49 square miles of the county inside the 1%-annual-chance floodplain it uses for inland flooding.1
- 16 inland flood events in FEMA's record, about 0.6 a year.1
- 1 federal disaster declaration for flooding.3
What it means for a buyer or owner
Beyond the roughly 49 square miles of mapped floodplain in Martin County, rain-driven flooding follows rivers, lakes, wetlands and canals, and it doesn't stop at the mapped lines: FEMA says more than 20% of flood insurance claims come from outside high-risk areas.
Ask whether the home has flooded or had a flood claim, and look at the lot's elevation in the report.

Tornadoes
Relatively ModerateThe local numbers
- FEMA rates tornado risk in Martin County "Relatively Moderate" (score 74.8 of 100, compared with every U.S. county).1

- 22 tornadoes recorded in the county in FEMA's index (NOAA Storm Prediction Center records), about 0.4 a year.1
- 1 federal disaster declaration for tornadoes.3
What it means for a buyer or owner
With roughly 0.4 tornadoes a year on record, Martin County sees mostly brief, narrow touchdowns, often spun up by tropical systems and spring squall lines, so damage is very local. The same roof-to-wall connections that resist hurricane wind help here.
Check the roof covering, any hurricane straps or clips, and the insurer's windstorm deductible.

- 11.2% of the county's building value is in areas FEMA treats as exposed to wildfire.1
- 6 federal fire declarations (including fire-management grants) have covered the county.3
What it means for a buyer or owner
11.2% of the building value in Martin County is near burnable land; risk is highest where homes back onto pine flatwoods, scrub, prairie or other wild land, especially in the dry late-winter and spring months.
Look at the vegetation around the lot, keep a clear zone around the house, and check for burn bans and prescribed-burn areas nearby.
