Lowest Risk in New York

Seneca County's score of 41.83 is dramatically lower than New York's state average of 69.42, ranking it in the state's safest tier. This 27-point advantage means residents face significantly reduced exposure to natural disasters compared to most other New York counties.

Safer Than Surrounding Counties

Seneca County's risk score is substantially lower than neighboring Tioga County (59.86) and Tompkins County (73.86). This safety advantage extends across most hazard categories, making it one of the region's most resilient areas.

Watch for Flooding and Hurricanes

Flood risk (63.65) and hurricane risk (59.41) are Seneca County's top concerns, though both remain moderate compared to state averages. Tornado risk is minimal at 30.79, and wildfire exposure presents little threat to most properties in the county.

Insurance Remains Essential Protection

Even in low-risk Seneca County, flood and hurricane coverage should be part of your insurance strategy, particularly near water bodies and low-lying areas. Standard homeowners policies typically exclude both flood and wind damage, requiring separate coverage for complete protection.
