Risk Overview

About Natural Disaster Risk in Livingston Parish, Louisiana

Livingston Parish: Extreme National Risk

Livingston Parish scores 94.47 with a Relatively High risk rating, placing it among the most disaster-exposed counties in the United States. Your parish's southeast Louisiana location subjects it to overlapping hurricane, flood, tornado, and earthquake hazards found in very few American regions.

Third-Highest Risk in Louisiana

Livingston Parish ranks third among Louisiana's 64 parishes with a composite score of 94.47, far exceeding the state average of 62.37. Only Jefferson and Lafayette parishes surpass your parish's hazard exposure profile.

Core of Louisiana's Maximum-Risk Zone

Neighboring Jefferson Parish (98.66) and Lafayette Parish (95.17) form a contiguous high-risk cluster with Livingston Parish, creating one of America's most disaster-prone regional corridors. Your parish sits at the geographic heart of extreme vulnerability.

Tornadoes and Hurricanes Converge Here

Tornado risk (95.67) and hurricane risk (97.62) are Livingston Parish's defining hazards, both ranking among the nation's highest individual risk scores. Flood risk (94.94) compounds these threats, creating a nearly perfect storm of overlapping disaster types.

Comprehensive, Layered Coverage Essential

Livingston Parish residents must maintain homeowners insurance with maximum hurricane/wind coverage, mandatory flood insurance (especially in FEMA high-risk zones), and strongly consider tornado-resistant construction for new builds. Schedule annual policy reviews with a local agent and keep detailed home documentation for rapid claims processing after disasters.

Risk Advisory: Livingston Parish

Risk Verdict

Natural hazard exposure in Livingston Parish is notably high, placing it at the 94th percentile among all U.S. counties. Livingston Parish's elevated composite score reflects cumulative multi-hazard exposure; households should prepare for the county's two or three primary hazard types.

Hazard Breakdown

Hurricane risk is Livingston Parish's dominant natural hazard, ranked at the 98th percentile nationally under FEMA's National Risk Index. Tornado ranks second at the 96th percentile nationally. Additional tracked hazards include flood (95th percentile), earthquake (58th percentile), wildfire (57th percentile).

Preparedness Context

At the 98th percentile nationally for hurricane risk, Livingston Parish is in a zone where flood insurance matters beyond the primary wind risk: NFIP flood insurance requires a 30-day waiting period before taking effect, making off-season enrollment the correct timing. Livingston Parish's tornado exposure at the 96th percentile nationally adds a hazard layer that can persist or intensify after hurricane-force winds have passed, particularly in low-lying inland areas. For Livingston Parish households, the hurricane preparedness calendar matters: flood insurance has a 30-day waiting period, wind-hardening retrofits take weeks to schedule, and evacuation route scouting is best done before a storm watch is issued.

Regional Context

A composite score 32.1 points above the Louisiana state average puts Livingston Parish in a higher-risk category than most counties in the state.

Percentile scores rank each county against all 3,144 U.S. counties, and risk ratings range from Very Low to Very High.
Why is Livingston Parish higher risk than average?
Livingston Parish's composite risk score of 94th percentile is above the Louisiana state average of 62th percentile.
