Fostoria's Seismic Design Category, explained

Under the seismic model IBC and ASCE 7 use for new construction, Fostoria 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 Fostoria sits at the 47th percentile for seismic hazard among 4,875 US cities.

Fostoria by the numbers

USGS's underlying values for Fostoria: 0.073g peak ground acceleration, 0.138g at short period, 0.056g at 1 second. Within Ohio alone, Fostoria ranks 80 of 254 cities by seismic hazard - the 69th percentile in-state. Fostoria has a population of about 13,063.

What a retrofit costs in Fostoria

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 Ohio 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 Ohio.

Insuring against this, not just retrofitting

A Fostoria 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 Fostoria's figures come from

Fostoria'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 Fostoria.
