Risk Overview

About Natural Disaster Risk in Chemung County, New York

Chemung ranks among safer U.S. counties

With a composite risk score of 54.77 and a relatively low rating, Chemung County sits well below the national average in disaster exposure. This favorable position allows for more selective insurance and preparedness strategies.

One of New York's safest counties

Chemung's 54.77 score ranks among the lowest in New York, sitting notably below the state average of 69.42. It consistently underperforms the state on major hazard categories, making it one of the safer regions to live in.

Safest county in its region

Chemung County's 54.77 score is the lowest among nearby counties, including Broome (87.47), Cattaraugus (81.58), and Allegany (69.75). Its inland location and terrain provide natural protection from major disaster exposure.

Floods present the primary concern

Flood risk at 72.17 is your main hazard, though tornado risk (52.83) and hurricane risk (66.33) both remain moderate and manageable. Chemung's location along river corridors creates seasonal flood vulnerability despite its generally safer profile.

Basic flood coverage is prudent

While Chemung faces lower overall risk, flood insurance at 72.17 remains smart protection since standard homeowners policies exclude flood damage. A solid homeowners policy covering wind and liability should adequately address your remaining hazards in this relatively safe county.
