About Natural Disaster Risk in Lamoille County, Vermont

Lamoille ranks among America's safest

Lamoille County's composite risk score of 18.26 places it well below the national average with a "Very Low" rating. Its position in central Vermont's mountains provides natural protection from most major hazard types.

Fourth-safest county in Vermont

Lamoille County ranks fourth lowest statewide with a score of 18.26, substantially below Vermont's average of 36.44. Only Essex, Grand Isle, and Franklin counties register lower overall risk profiles in the state.

Safer than most surrounding counties

Lamoille's risk score of 18.26 stands notably below Chittenden County (63.90) to the northwest and Caledonia County (30.15) to the northeast. Its mountain setting creates buffering effects against multiple hazard types.

Hurricanes and floods are top concerns

Lamoille County's primary exposures come from hurricane risk (61.62) and flood risk (42.81), reflecting Atlantic weather systems and the Lamoille River valley's geography. Earthquake risk (40.49) presents a modest but manageable tertiary concern.

Flood insurance worth considering

Lamoille residents should secure comprehensive homeowners insurance with strong wind coverage for hurricane season. Flood insurance through the NFIP is advisable for properties in or near mapped flood zones along major river valleys.
