Does Berea, KY need an earthquake retrofit?

USGS's ASCE 7-16 seismic design model - the same standard building codes use - places Berea in Seismic Design Category C: Moderate seismic hazard. Code adds irregular-building restrictions and requires bracing of some nonstructural components (e.g. tall shelving, water heaters) in addition to structural detailing. Nationally, Berea ranks above 69% of the 4,875 cities in this dataset for seismic hazard - the 69th percentile.

Where Berea sits in Kentucky

The raw figures: peak ground acceleration 0.091g, short-period spectral response 0.181g, 1-second spectral response 0.084g. Among 79 Kentucky cities in this dataset, Berea ranks 30 for seismic hazard, the 63th percentile within the state. About 16,436 people live in Berea, Kentucky.

Bracing and bolting: the actual cost

Outside California, no state-level retrofit grant equivalent to Brace + Bolt could be found for Kentucky. A typical retrofit still runs $5,000-$10,000 nationally, about $7,000 for a common single-family job.

Earthquake insurance for a Berea home

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 Berea address.
