Steubenville's Seismic Design Category, explained

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

How Steubenville compares

The raw figures: peak ground acceleration 0.044g, short-period spectral response 0.092g, 1-second spectral response 0.047g. Among 254 Ohio cities in this dataset, Steubenville ranks 253 for seismic hazard, the 0th percentile within the state. About 18,029 people live in Steubenville, Ohio.

Retrofit economics for Steubenville

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

Insuring against this, not just retrofitting

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 Steubenville address.

More on how this number was built
