Wake Forest's Seismic Design Category, explained

USGS's ASCE 7-16 seismic design model - the same standard building codes use - places Wake Forest in Seismic Design Category B: 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 Wake Forest sits at the 33th percentile for seismic hazard among 4,875 US cities.

Wake Forest by the numbers

The raw figures: peak ground acceleration 0.054g, short-period spectral response 0.113g, 1-second spectral response 0.057g. Among 147 North Carolina cities in this dataset, Wake Forest ranks 125 for seismic hazard, the 15th percentile within the state. About 56,764 people live in Wake Forest, North Carolina.

What a retrofit costs in Wake Forest

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

Insuring against this, not just retrofitting

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 Wake Forest address.

More on how this number was built
