Alongside flooding, hurricane exposure at the 26th percentile means households benefit from a multi-hazard preparedness plan rather than focusing on flood alone. Regardless of specific hazard, Alpena County households benefit from a practiced communication plan: a designated out-of-state contact and a pre-agreed evacuation destination established before the season's peak risk period.
