Meriden's Seismic Design Category, explained

USGS's ASCE 7-16 seismic design model - the same standard building codes use - places Meriden in Seismic Design Category B: Low seismic hazard. Code requires basic seismic detailing (bracing, connections) but no special structural system restrictions. Rank it against the rest of the country and Meriden sits at the 59th percentile for seismic hazard among 4,875 US cities.

Where Meriden sits in Connecticut

The raw figures: peak ground acceleration 0.113g, short-period spectral response 0.204g, 1-second spectral response 0.055g. Among 21 Connecticut cities in this dataset, Meriden ranks 8 for seismic hazard, the 65th percentile within the state. About 60,849 people live in Meriden, Connecticut.

Bracing and bolting: the actual cost

Outside California, no state-level retrofit grant equivalent to Brace + Bolt could be found for Connecticut. A typical retrofit still runs $5,000-$10,000 nationally, about $7,000 for a common single-family job.

What this means for insurance

Outside California, earthquake coverage is typically sold as an endorsement added to a standard homeowners policy, not a separate product - worth asking about directly when getting a home-insurance quote for a Meriden address.

More on how this number was built

The methodology guide covers exactly how USGS's public design-maps API produced Meriden's numbers. The guide to what a Seismic Design Category actually means covers why a category is never a substitute for an engineer's assessment of one specific house.
