Waterbury, CT: what USGS's seismic model says

USGS's ASCE 7-16 seismic design model - the same standard building codes use - places Waterbury in Seismic Design Category B: Low seismic hazard.

Nationally, Waterbury ranks above 57% of the 4,875 cities in this dataset for seismic hazard - the 57th percentile.

Where Waterbury sits in Connecticut

USGS's underlying values for Waterbury: 0.106g peak ground acceleration, 0.193g at short period, 0.054g at 1 second. Within Connecticut alone, Waterbury ranks 14 of 21 cities by seismic hazard - the 35th percentile in-state. Waterbury has a population of about 115,908.

Retrofit economics for Waterbury

A full earthquake retrofit typically runs $5,000-$10,000 nationally (around $7,000 typical), driven mainly by house size and foundation type, not by Connecticut specifically. California's Earthquake Brace + Bolt grant, which covers a large share of this cost, is a California-only program and does not apply in Connecticut.

Earthquake insurance for a Waterbury home

A Waterbury homeowner cannot buy a standalone earthquake policy in most cases - it is added to an existing homeowners policy as an endorsement, so the place to start is a regular home-insurance quote.
