Risk Overview

About Natural Disaster Risk in Southeastern Connecticut Planning Region, Connecticut

Southeastern Connecticut moderately above average

Southeastern Connecticut Planning Region scores 88.64 on the composite risk scale, placing it in the relatively moderate category and just slightly above Connecticut's state average of 87.62. This profile reflects balanced exposure across coastal and inland hazards.

Mid-range risk among Connecticut regions

Southeastern Connecticut ranks fifth among Connecticut's eight planning regions, sitting comfortably in the middle of the state's risk distribution. Its 88.64 score reflects a mixed coastal-suburban geography with moderate multi-hazard exposure.

Similar risk to other coastal peers

Southeastern Connecticut's 88.64 score closely mirrors Greater Bridgeport (91.76) and Lower Connecticut River Valley (83.84), reflecting shared coastal characteristics. The region ranks lower than Naugatuck Valley (93.19) but higher than inland planning regions.

Hurricanes and flooding top your hazard list

Hurricane risk (94.74) and flood risk (91.83) dominate the hazard landscape, reflecting the region's coastal position and exposure to Atlantic storm systems. Earthquake risk (80.95) and tornado risk (53.09) add secondary but measurable threats.

Coastal flood insurance is essential coverage

Flood insurance must be a priority for Southeastern Connecticut residents, particularly those in coastal areas or flood-prone zones—your 91.83 flood risk score makes this non-negotiable. Verify your homeowners policy covers hurricane-force winds, and consider additional liability protection given your region's significant coastal exposure.
