Newnan's Seismic Design Category, explained

Newnan 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. That puts Newnan in the 49th percentile nationally for seismic hazard - higher than 49% of the 4,875 US cities USGS was checked against here.

How Newnan compares

The raw figures: peak ground acceleration 0.077g, short-period spectral response 0.159g, 1-second spectral response 0.081g. Among 148 Georgia cities in this dataset, Newnan ranks 117 for seismic hazard, the 21th percentile within the state. About 45,548 people live in Newnan, Georgia.

What a retrofit costs in Newnan

Outside California, no state-level retrofit grant equivalent to Brace + Bolt could be found for Georgia. A typical retrofit still runs $5,000-$10,000 nationally, about $7,000 for a common single-family job.

What this means for insurance

Outside California, earthquake coverage is typically sold as an endorsement added to a standard homeowners policy, not a separate product - worth asking about directly when getting a home-insurance quote for a Newnan address.

More on how this number was built
