Utica's Seismic Design Category, explained

Under the seismic model IBC and ASCE 7 use for new construction, Utica is 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 Utica sits at the 25th percentile for seismic hazard among 4,875 US cities.

How Utica compares

USGS's underlying values for Utica: 0.045g peak ground acceleration, 0.091g at short period, 0.043g at 1 second. Within Michigan alone, Utica ranks 92 of 153 cities by seismic hazard - the 40th percentile in-state. Utica has a population of about 5,139.

What a retrofit costs in Utica

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 Michigan 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 Michigan.

What this means for insurance

A Utica 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.

Where Utica's figures come from

Utica's Category B and every number above trace to USGS's own ASCE 7-16 Design Maps service - see the methodology guide. See the category explainer for what Category B does and doesn't tell you about Utica.
