Edgewood's Seismic Design Category, explained

Under the seismic model IBC and ASCE 7 use for new construction, Edgewood is Category B. Low seismic hazard. Code requires basic seismic detailing (bracing, connections) but no special structural system restrictions. That puts Edgewood in the 47th percentile nationally for seismic hazard - higher than 47% of the 4,875 US cities USGS was checked against here.

Where Edgewood sits in Kentucky

USGS's underlying values for Edgewood: 0.073g peak ground acceleration, 0.148g at short period, 0.078g at 1 second. Within Kentucky alone, Edgewood ranks 70 of 79 cities by seismic hazard - the 12th percentile in-state. Edgewood has a population of about 8,526.

Retrofit economics for Edgewood

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 Edgewood 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 Edgewood's figures come from

Edgewood'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 Edgewood.
