Brunswick's Seismic Design Category, explained

Brunswick 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 Brunswick sits at the 50th percentile for seismic hazard among 4,875 US cities.

Where Brunswick sits in Georgia

USGS's underlying values for Brunswick: 0.079g peak ground acceleration, 0.158g at short period, 0.073g at 1 second. Within Georgia alone, Brunswick ranks 115 of 148 cities by seismic hazard - the 22th percentile in-state. Brunswick has a population of about 15,520.

What a retrofit costs in Brunswick

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 Brunswick 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 Brunswick's figures come from

Brunswick'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 Brunswick.
