Chardon by the numbers

USGS's underlying values for Chardon: 0.088g peak ground acceleration, 0.159g at short period, 0.049g at 1 second. Within Ohio alone, Chardon ranks 18 of 254 cities by seismic hazard - the 93th percentile in-state. Chardon has a population of about 5,233.

What a retrofit costs in Chardon

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.

What this means for insurance

A Chardon 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 Chardon's figures come from

Chardon'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 Chardon.
