Port Clinton's Seismic Design Category, explained

Under the seismic model IBC and ASCE 7 use for new construction, Port Clinton is Category B. Low seismic hazard. Code requires basic seismic detailing (bracing, connections) but no special structural system restrictions. Nationally, Port Clinton ranks above 43% of the 4,875 cities in this dataset for seismic hazard - the 43th percentile.

Where Port Clinton sits in Ohio

USGS's underlying values for Port Clinton: 0.068g peak ground acceleration, 0.13g at short period, 0.052g at 1 second. Within Ohio alone, Port Clinton ranks 159 of 254 cities by seismic hazard - the 38th percentile in-state. Port Clinton has a population of about 5,915.

Bracing and bolting: the actual cost

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 Port Clinton 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 Port Clinton's figures come from

Port Clinton'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 Port Clinton.
