Canal Winchester's Seismic Design Category, explained

USGS's ASCE 7-16 seismic design model - the same standard building codes use - places Canal Winchester in Seismic Design Category B: Low seismic hazard. Code requires basic seismic detailing (bracing, connections) but no special structural system restrictions. Nationally, Canal Winchester ranks above 34% of the 4,875 cities in this dataset for seismic hazard - the 34th percentile.

Where Canal Winchester sits in Ohio

The raw figures: peak ground acceleration 0.057g, short-period spectral response 0.115g, 1-second spectral response 0.059g. Among 254 Ohio cities in this dataset, Canal Winchester ranks 217 for seismic hazard, the 15th percentile within the state. About 10,060 people live in Canal Winchester, 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 Canal Winchester address.
