Risk Overview

About Natural Disaster Risk in Chautauqua County, New York

Chautauqua faces moderate-to-high risk

With a composite risk score of 84.64 and a relatively moderate rating, Chautauqua County ranks above the national average in disaster exposure. Its waterfront position and regional hazard convergence create compounded vulnerability.

Well above state average for risk

Chautauqua's 84.64 score significantly exceeds New York's 69.42 state average, placing it among the higher-risk counties statewide. Only a few counties face comparable or greater exposure.

Riskier than western region peers

Chautauqua County's 84.64 score exceeds Allegany County (69.75) to the south and Cattaraugus County (81.58) to the east, though it sits slightly below Broome County (87.47) far to the east. Its Lake Erie shoreline and western New York location drive elevated risk.

Floods and tornadoes lead threats

Flood risk reaches 91.28—among the state's highest—while tornado risk stands at 76.14, and wildfire risk at 43.13 exceeds most county neighbors. Chautauqua's position along Lake Erie and in a storm corridor amplifies both water and wind hazards.

Prioritize flood and wind coverage

Flood insurance is essential at 91.28 risk; verify coverage even if you believe you're outside floodplain zones. Ensure your homeowners policy explicitly covers wind and tornado damage, and keep your home's roof and structure in good repair to withstand high winds.
