Most hazardous county in its region

Lawrence County's 70.99 composite score exceeds most adjacent Appalachian counties in the southern part of the state. Its elevated flood risk particularly distinguishes it from neighboring areas with lower riverine exposure.

Floods and wildfires pose distinct threats

Flood risk dominates at 83.75, reflecting the county's river systems and topography, while wildfire exposure (53.24) significantly exceeds state averages. Tornadoes (48.25) remain a secondary concern but still present measurable risk.

Prioritize flood and wildfire insurance

Lawrence County's extreme flood risk makes flood insurance non-negotiable, especially for properties near the Ohio River and tributary systems. Homeowners in wooded areas should also ensure their policies include adequate wildfire and wind coverage.
