Risk Overview
Overall natural disaster risk in Lampasas County is very low, with a National Risk Index score of 29.9 out of 100 — placing it in the 30th 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 wildfire (uncontrolled fires that spread across wildland and into communities) at Low risk — $502K in expected annual loss and about 0.00 events per year; hail (ice stones from severe thunderstorms that damage property and crops) at Low risk — $485K in expected annual loss and about 4.70 events per year; and tornado (violently rotating columns of air capable of catastrophic local damage) at Low risk — $1M in expected annual loss and about 0.35 events per year. Across all hazards, FEMA estimates $8M in expected annual loss for a population of 22K.
Beyond physical exposure, Lampasas County has a 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: Lampasas County has received 19 federal disaster declarations since 1991, including 6 for fire events and 3 for flood events. The most recent was Severe Storms, Straight-Line Winds, and Flooding (flood), declared in July 2025.
Among 254 Texas counties, Lampasas County ranks #170 for overall natural disaster risk.
