Passaic County's composite risk score ranks at the 96th percentile nationally, reflecting genuine multi-hazard exposure for residents. At this risk level, having a documented household preparedness plan — not just awareness — is the meaningful next step for Passaic County residents.
Hazard Breakdown
Flood risk is Passaic County's dominant natural hazard, ranked at the 98th percentile nationally under FEMA's National Risk Index. Earthquake ranks second at the 94th percentile nationally. Additional tracked hazards include tornado (89th percentile), hurricane (88th percentile), wildfire (16th percentile).
Preparedness Context
At the 98th percentile nationally for flood risk, Passaic County residents benefit from understanding their specific flood zone status. Even one inch of floodwater causes significant structural damage to properties outside officially designated high-risk zones. Secondary earthquake exposure at the 94th percentile adds a second preparedness layer; households should review coverage options and alert sign-up for both hazard types. A tested family preparedness plan specific to Passaic County's primary hazards — including how to shelter in place or evacuate, and who to call — provides more real protection than a general emergency kit sitting unused on a shelf.
Regional Context
The New Jersey county average is 5.0 composite points below Passaic County's score, a gap that reflects the county's elevated position in the state's hazard distribution.
