Risk Overview
Dutchess County carries a medium composite natural disaster risk, with a National Risk Index score of 88.3 out of 100 — placing it in the 88th national percentile and near the national midpoint for natural-disaster risk. The score blends Expected Annual Loss, Social Vulnerability, and Community Resilience across all 18 FEMA hazard types.
Most of Dutchess County's expected losses come from riverine flood (rivers and streams overflowing their banks after heavy rain or snowmelt) at Medium risk — $60M in expected annual loss and about 1.93 events per year; landslide (downhill movement of rock, soil, and debris on unstable slopes) at Medium risk — $85K in expected annual loss and about 1.24 events per year; and hurricane (tropical cyclones bringing extreme wind, rain, and storm surge) at Medium risk — $10M in expected annual loss and about 0.10 events per year. Across all hazards, FEMA estimates $85M in expected annual loss for a population of 296K.
Beyond physical exposure, Dutchess County has a low social vulnerability rating (how susceptible the population is to harm) and a high community resilience rating (its capacity to prepare for and recover from disasters). A less vulnerable population paired with strong resilience helps the community absorb and recover from events.
The county's disaster history tells the same story: Dutchess County has received 27 federal disaster declarations since 1965, including 7 for hurricane events and 6 for severe storm events. The most recent was Severe Storms and Flooding (severe storm), declared in July 2023.
