Risk Overview
Greensville County carries a very low composite natural disaster risk, with a National Risk Index score of 17.8 out of 100 — placing it in the 18th national percentile and among the lowest-risk counties in the country. The score blends Expected Annual Loss, Social Vulnerability, and Community Resilience across all 18 FEMA hazard types.
Risk here concentrates in drought (extended dry periods that stress water supplies and agriculture) at High risk — $1M in expected annual loss and about 7.74 events per year; hurricane (tropical cyclones bringing extreme wind, rain, and storm surge) at Low risk — $1M in expected annual loss and about 0.19 events per year; and winter weather (heavy snow, blizzards, and hazardous winter conditions) at Low risk — $36K in expected annual loss and about 4.47 events per year. Across all hazards, FEMA estimates $4M in expected annual loss for a population of 11K.
Beyond physical exposure, Greensville County has a very high social vulnerability rating (how susceptible the population is to harm) and a low community resilience rating (its capacity to prepare for and recover from disasters). That combination — a more vulnerable population with limited resilience — can amplify the human cost of any given event.
The county's disaster history tells the same story: Greensville County has received 17 federal disaster declarations since 1977, including 7 for hurricane events and 3 for severe storm events. The most recent was Severe Winter Storm (winter storm), declared in January 2026.
Among 133 Virginia counties, Greensville County ranks #85 for overall natural disaster risk.
