Lowest-risk planning region in the state

Safest option among coastal regions
Lower Connecticut River Valley's 83.84 score outperforms nearly all neighboring planning regions, trailing only Northwest Hills (79.61) and Northeastern Connecticut (62.75). Among coastal and mixed-geography areas, it offers the most balanced risk profile.
Riverine flooding is your primary concern
Flood risk (90.33) is the dominant hazard, though notably lower than in more coastal regions, reflecting the importance of river management and floodplain awareness. Hurricane (87.69) and wildfire (43.64) risks are moderate, while tornado and earthquake threats remain secondary.
River valley properties need flood insurance
