Napoleon, OH: what USGS's seismic model says

Napoleon carries Seismic Design Category B under USGS's ASCE 7-16 model. 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 Napoleon sits at the 48th percentile for seismic hazard among 4,875 US cities.

Where Napoleon sits in Ohio

The raw figures: peak ground acceleration 0.074g, short-period spectral response 0.14g, 1-second spectral response 0.057g. Among 254 Ohio cities in this dataset, Napoleon ranks 72 for seismic hazard, the 72th percentile within the state. About 8,724 people live in Napoleon, Ohio.

Bracing and bolting: the actual cost

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 Napoleon address.
