Risk Overview
FEMA's National Risk Index rates Boyd County at low composite risk, with a National Risk Index score of 74.9 out of 100 — placing it in the 75th national percentile and below the national average for natural-disaster risk. The score blends Expected Annual Loss, Social Vulnerability, and Community Resilience across all 18 FEMA hazard types.
The county's risk is driven primarily by heat wave (prolonged periods of extreme heat that threaten health and infrastructure) at High risk — $7M in expected annual loss and about 4.53 events per year; landslide (downhill movement of rock, soil, and debris on unstable slopes) at Low risk — $21K in expected annual loss and about 0.41 events per year; and riverine flood (rivers and streams overflowing their banks after heavy rain or snowmelt) at Medium risk — $19M in expected annual loss and about 2.75 events per year. Across all hazards, FEMA estimates $29M in expected annual loss for a population of 48K.
Beyond physical exposure, Boyd County has a medium social vulnerability rating (how susceptible the population is to harm) and a medium community resilience rating (its capacity to prepare for and recover from disasters). Both measures sit toward the lower end, indicating relatively modest population sensitivity.
The federal record bears this out: Boyd County has received 33 federal disaster declarations since 1967, including 16 for severe storm events and 6 for flood events. The most recent was Severe Winter Storm (winter storm), declared in January 2026.
Among 120 Kentucky counties, Boyd County ranks #14 for overall natural disaster risk.
