Risk Overview

About Natural Disaster Risk in Northwest Hills Planning Region, Connecticut

Northwest Hills below state average risk

Northwest Hills Planning Region scores 79.61 on the composite risk scale, placing it in the relatively low category and well below Connecticut's state average of 87.62. This favorable profile reflects limited coastal exposure and lower urban density compared to other planning regions.

Second-safest planning region in state

Northwest Hills ranks second-lowest (most favorable) among Connecticut's eight planning regions, surpassed in safety only by Northeastern Connecticut's 62.75 score. Its 79.61 score represents a notably safer profile than the state average.

Safest inland region in Connecticut

Northwest Hills' 79.61 score exceeds only Northeastern Connecticut (62.75) among all regions and significantly outperforms nearby Lower Connecticut River Valley (83.84). As an inland, rural region, it offers one of the state's most favorable risk profiles.

Flooding remains your primary hazard

Flood risk (88.01) is the primary concern for Northwest Hills, reflecting seasonal precipitation and stream flooding in this terrain. Hurricane (86.78) and tornado (42.88) risks are secondary, while wildfire (39.95) and earthquake (66.32) threats are comparatively minimal.

Flood insurance recommended for vulnerable properties

Properties in flood-prone areas or near streams should secure separate flood insurance, as standard homeowners policies exclude this hazard—particularly important given your 88.01 flood risk score. For most inland properties on higher ground, standard coverage is typically sufficient to protect against the region's moderate overall hazards.

A tested family preparedness plan specific to Northwest Hills Planning Region's primary hazards — including how to shelter in place or evacuate, and who to call — provides more real protection than a general emergency kit sitting unused on a shelf.
