Hazard Breakdown

Flood risk is Portage County's dominant natural hazard, ranked at the 75th percentile nationally under FEMA's National Risk Index. Tornado ranks second at the 70th percentile nationally. Additional tracked hazards include hurricane (55th percentile), earthquake (53th percentile), wildfire (39th percentile).

Preparedness Context

Flood risk is Portage County's top hazard at the 75th percentile nationally. Households in or near designated flood zones face elevated financial exposure; flood insurance typically requires a 30-day waiting period before it takes effect, so applying before the season is advisable. The county's second-ranked hazard, tornado at the 70th percentile nationally, means Portage County residents face compounding risks from multiple natural hazard types during peak seasons. Households across Portage County should identify the nearest community shelter and keep a basic emergency kit — water, non-perishable food, medications, flashlight, and battery radio — in a location easy to grab quickly.

Regional Context
