Risk Overview

About Natural Disaster Risk in Union County, Georgia

Union County faces moderate disaster risk

Union County's composite risk score of 52.48 ranks in the relatively low category but exceeds Georgia's state average of 39.49. This north-Georgia mountain county experiences elevated natural hazard exposure compared to most of the state.

Mid-to-upper range among Georgia counties

Union County ranks above the state median for composite hazard risk among Georgia's 159 counties, placing it in the higher-risk half. Its 52.48 score reflects consistent above-average threats, particularly from wildfire and flood exposure.

Riskier than Towns County, safer than Troup

Union County's 52.48 score falls between nearby Towns County (39.60) and Troup County (59.92), positioning it as a moderate-risk area in the Georgia mountains. Its wildfire and flood scores notably exceed those of lower-elevation counties.

Wildfire and flooding are dual threats

Wildfire risk reaches 71.88 and flood risk 58.68—both well above state averages and reflecting Union County's mountain geography and forest coverage. Tornado risk (63.17) also poses a notable secondary threat to residents and property.

Flood and wildfire coverage essential

Union County residents should prioritize flood insurance given the 58.68 flood risk and consider wildfire coverage options for the 71.88 wildfire score. These two hazards pose the greatest financial threats and require protection beyond standard homeowners policies.

Risk Advisory: Union County

Risk Verdict

At the 52th percentile nationally, Union County experiences a manageable level of natural hazard risk that falls below the U.S. median. Union County's risk profile calls for targeted preparedness, focusing on the hazard categories that dominate the county's score.

Hazard Breakdown

Wildfire risk is Union County's dominant natural hazard, ranked at the 72th percentile nationally under FEMA's National Risk Index. Earthquake ranks second at the 64th percentile nationally. Additional tracked hazards include tornado (63th percentile), flood (59th percentile), hurricane (56th percentile).

Preparedness Context

Wildfire ranks as Union County's primary hazard at the 72th percentile nationally. For Union County households in high-WUI areas, go-bag readiness — the ability to leave within 15 minutes — is more important than shelter-in-place planning for most residential properties. The county's earthquake exposure at the 64th percentile nationally complements the wildfire risk — saturating rain after burn scarring often triggers secondary flood and debris flow events. Union County county's local emergency management office publishes community-specific wildfire risk assessments and evacuation zone maps; households should review their zone assignment and sign up for zone-specific alerts.

Regional Context

Union County falls 13.0 points above Georgia's typical county risk level, which means the hazard environment here is notably more demanding than the state baseline.

Frequently Asked Questions

What is the natural disaster risk in Union County, GA?
Union County has a FEMA National Risk Index rating of Relatively Low, placing it in the 52th percentile nationally out of 3,144 counties. This composite score reflects the county's overall exposure to natural hazards including floods, wildfires, tornadoes, earthquakes, and hurricanes, weighted by expected annual loss and social vulnerability.
What types of natural hazards affect Union County?
Union County is evaluated for five major natural hazard types: wildfire (72th percentile), earthquake (64th percentile), tornado (63th percentile), flooding (59th percentile), hurricane (56th percentile). The highest-risk hazard is wildfire at the 72th percentile nationally. These scores are derived from FEMA's National Risk Index, which analyzes expected annual loss, social vulnerability, and community resilience for each hazard type.
How does Union County risk compare to the Georgia average?
Union County's composite risk percentile is 52th, compared to the Georgia state average of 40th percentile. The state's overall risk rating is Very Low. This means Union County faces higher natural disaster risk than the typical county in Georgia.

Yes, Union County's wildfire risk is at the 72th percentile nationally. This is above the national median. For flooding specifically, Union County is at the 59th percentile.
How is natural disaster risk measured?
FEMA's National Risk Index (NRI) calculates risk scores for 18 natural hazard types across all U.S. counties and census tracts. The composite score combines Expected Annual Loss (estimated dollar losses from each hazard), Social Vulnerability (demographic factors affecting disaster impact), and Community Resilience (ability to recover). Percentile scores rank each county against all 3,144 U.S. counties, and risk ratings range from Very Low to Very High.
Why is Union County higher risk than average?
Union County's composite risk score of 52th percentile is above the Georgia state average of 40th percentile. This elevated risk is driven by wildfire exposure (72th percentile), along with earthquake and tornado and flooding and hurricane risk. Geographic location, terrain, climate patterns, and proximity to flood zones or fault lines all influence a county's risk profile.
