Byron's Seismic Design Category, explained

Byron carries Seismic Design Category B under USGS's ASCE 7-16 model. Low seismic hazard. Code requires basic seismic detailing (bracing, connections) but no special structural system restrictions. Rank it against the rest of the country and Byron sits at the 50th percentile for seismic hazard among 4,875 US cities.

How Byron compares

USGS's underlying values for Byron: 0.081g peak ground acceleration, 0.161g at short period, 0.074g at 1 second. Within Georgia alone, Byron ranks 110 of 148 cities by seismic hazard - the 26th percentile in-state. Byron has a population of about 6,305.

Retrofit economics for Byron

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 Georgia 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 Georgia.

What this means for insurance

A Byron 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 Byron's figures come from

Byron'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 Byron.
