Strongsville, OH: what USGS's seismic model says

USGS's ASCE 7-16 seismic design model - the same standard building codes use - places Strongsville 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 Strongsville sits at the 45th percentile for seismic hazard among 4,875 US cities.

Strongsville by the numbers

The raw figures: peak ground acceleration 0.07g, short-period spectral response 0.132g, 1-second spectral response 0.05g. Among 254 Ohio cities in this dataset, Strongsville ranks 117 for seismic hazard, the 54th percentile within the state. About 45,768 people live in Strongsville, 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 Strongsville address.
