Risk Overview

About Natural Disaster Risk in Polk County, Nebraska

Polk County sits at state-level risk profile

Polk County's composite risk score of 25.70 places it in the Very Low category and nearly matches the national average. This balanced exposure reflects moderate, non-catastrophic hazard threats across multiple disaster types.

Slightly above Nebraska's average

Polk County's score of 25.70 edges slightly above Nebraska's state average of 25.80, placing it near the midpoint of the state's risk rankings. This near-average position reflects a fairly typical hazard profile for central Nebraska.

Moderate risk compared to surrounding area

Polk County's 25.70 score positions it between the region's safer counties like Perkins (4.36) and higher-risk areas like Platte (70.58). Most surrounding counties cluster between 14 and 40, making Polk relatively typical for the area.

Tornado and wildfire lead hazard list

Tornado risk scores 36.80 and wildfire risk scores 38.39, making these Polk County's primary concerns despite relatively balanced overall exposure. Flood (16.44), earthquake (8.21), and hurricane risks remain secondary.

Standard coverage with wind emphasis

Polk County residents should ensure their homeowners insurance provides comprehensive wind damage coverage for tornadoes and wildfire protection. Given the balanced hazard profile, standard homeowners insurance combined with routine property maintenance should provide adequate protection against the county's moderate threats.

Risk Advisory: Polk County

Risk Verdict

Polk County's natural disaster risk is among the lowest in the country, with a composite score at the 26th percentile nationally. Residents of Polk County can use the 26th percentile ranking as a baseline, while recognizing that individual properties may still lie in specific hazard zones that differ from the county average.

Hazard Breakdown

Wildfire risk is Polk County's dominant natural hazard, ranked at the 38th percentile nationally under FEMA's National Risk Index. Tornado ranks second at the 37th percentile nationally. Additional tracked hazards include flood (16th percentile), earthquake (8th percentile).

Preparedness Context

Wildfire is Polk County's top-ranked natural hazard at the 38th percentile nationally. Polk County residents should assess whether their property lies within or adjacent to a Wildland-Urban Interface (WUI) zone, where ember transport and rapid spread pose the highest risk. Alongside wildfire, tornado at the 37th percentile nationally means a multi-season preparedness mindset — fire season and flood or storm season often require different household plans. For Polk County households, a practiced evacuation plan — with a primary and backup route designated before a fire occurs — provides more protection than any structural improvement when a wildfire approaches fast-moving terrain.

Regional Context

At just 0.1 composite points from the Nebraska average, Polk County's natural disaster risk is closely in line with its in-state peers.

Percentile scores rank each county against all 3,144 U.S. counties, and risk ratings range from Very Low to Very High.
Why is Polk County higher risk than average?
Polk County's composite risk score of 26th percentile is above the Nebraska state average of 26th percentile. This elevated risk is driven by wildfire exposure (38th percentile).
