Monticello's Seismic Design Category, explained
Under the seismic model IBC and ASCE 7 use for new construction, Monticello is 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. That puts Monticello in the 70th percentile nationally for seismic hazard - higher than 70% of the 4,875 US cities USGS was checked against here.
How Monticello compares
USGS's underlying values for Monticello: 0.101g peak ground acceleration, 0.203g at short period, 0.095g at 1 second. Within Kentucky alone, Monticello ranks 21 of 79 cities by seismic hazard - the 74th percentile in-state. Monticello has a population of about 5,726.
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.
What this means for insurance
A Monticello 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 Monticello's figures come from
Monticello'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 Monticello.
