Natural Disaster Risk in Union

Natural Hazard Profile: Union, Maine

Located along the northeastern Atlantic Seaboard in Knox County, Union is a town of roughly 4,023 residents. The humid continental climate that characterizes this part of Maine — marked by long, harsh winters and brief summers with heavy snowfall — directly influences the types and severity of natural hazards present, making Union a community where hazard awareness has real practical value.

FEMA rates Union's composite natural disaster risk at 5.8 out of 10 — moderate risk. Coastal flooding is the dominant hazard, with storm surge from tropical systems and nor'easters capable of inundating low-lying shoreline areas well above normal tidal levels. Residents should also account for winter and ice storm risk in their preparedness planning.

Relative to other U.S. communities, Union's natural disaster risk is above the U.S. national average of 4.5/10, slightly below the 6.2/10 state average. The hazard distribution here is led by coastal flood and winter, as measured by FEMA across Knox County. While city-specific sub-county variation exists, these scores represent the best available federal risk estimate.

Union's moderate risk profile means that while catastrophic events are less frequent, they do occur. Standard homeowners insurance typically covers many common hazards here, but confirming that coastal flood exposure is adequately protected is a worthwhile step for property owners.
