Does Bowling Green, KY need an earthquake retrofit?

Bowling Green carries Seismic Design Category D under USGS's ASCE 7-16 model. High seismic hazard - this is the category most of coastal California, the Pacific Northwest, and other active fault regions fall into. Code mandates significant seismic detailing and restricts irregular structural configurations. This is the category the Brace + Bolt scope (cripple-wall bracing, foundation bolting) is built for. Rank it against the rest of the country and Bowling Green sits at the 79th percentile for seismic hazard among 4,875 US cities.

Where Bowling Green sits in Kentucky

USGS's underlying values for Bowling Green: 0.12g peak ground acceleration, 0.247g at short period, 0.128g at 1 second. Within Kentucky alone, Bowling Green ranks 13 of 79 cities by seismic hazard - the 85th percentile in-state. Bowling Green has a population of about 79,076.

What a retrofit costs in Bowling Green

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 Kentucky 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 Kentucky.

What this means for insurance

A Bowling Green 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 Bowling Green's figures come from

Bowling Green's Category D 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 D does and doesn't tell you about Bowling Green.
