Vine Grove's Seismic Design Category, explained

Vine Grove carries Seismic Design Category C under USGS's ASCE 7-16 model. 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. That puts Vine Grove in the 70th percentile nationally for seismic hazard - higher than 70% of the 4,875 US cities USGS was checked against here.

How Vine Grove compares

USGS's underlying values for Vine Grove: 0.102g peak ground acceleration, 0.21g at short period, 0.109g at 1 second. Within Kentucky alone, Vine Grove ranks 19 of 79 cities by seismic hazard - the 77th percentile in-state. Vine Grove has a population of about 6,933.

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 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.

Earthquake insurance for a Vine Grove home

A Vine Grove 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 Vine Grove's figures come from

Vine Grove's Category C 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 C does and doesn't tell you about Vine Grove.
