Bessemer City, NC: what USGS's seismic model says

USGS's ASCE 7-16 seismic design model - the same standard building codes use - places Bessemer City in Seismic Design Category C: Moderate seismic hazard. Code adds irregular-building restrictions and requires bracing of some nonstructural components (e.g. tall shelving, water heaters) in addition to structural detailing. That puts Bessemer City in the 71th percentile nationally for seismic hazard - higher than 71% of the 4,875 US cities USGS was checked against here.

How Bessemer City compares

The raw figures: peak ground acceleration 0.108g, short-period spectral response 0.209g, 1-second spectral response 0.083g. Among 147 North Carolina cities in this dataset, Bessemer City ranks 23 for seismic hazard, the 85th percentile within the state. About 5,730 people live in Bessemer City, North Carolina.

Retrofit economics for Bessemer City

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.

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 Bessemer City address.
