Third-highest risk in Connecticut

Naugatuck Valley ranks third among Connecticut's eight planning regions, behind only South Central Connecticut (95.13) and Capitol Planning Region (97.36). This position reflects concentrated multi-hazard exposure in a mixed urban and suburban landscape.

Higher risk than inland neighbors

Naugatuck Valley's 93.19 score substantially exceeds nearby Northwest Hills (79.61) and Greater Bridgeport (91.76), placing it among the state's higher-risk regions. Only Capitol Planning Region to the north poses comparable or greater overall disaster risk.

Flooding and hurricanes drive your exposure

Flood risk (96.34) and hurricane risk (95.12) are nearly equivalent and represent your region's primary hazards, reflecting valley geography and proximity to coastal storm systems. Tornado risk (73.06) adds a secondary but significant threat, particularly during spring and fall seasons.

Bundle flood and wind coverage immediately

With flood risk at 96.34 and hurricane risk at 95.12, flood insurance is non-negotiable and wind damage coverage must be verified in your homeowners policy. Consider additional protection for your property given Naugatuck Valley's third-place ranking for state risk—standard policies often leave dangerous gaps.
