Lumberton, NC: what USGS's seismic model says

Under the seismic model IBC and ASCE 7 use for new construction, Lumberton is 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. Nationally, Lumberton ranks above 70% of the 4,875 cities in this dataset for seismic hazard - the 70th percentile.

How Lumberton compares

The raw figures: peak ground acceleration 0.103g, short-period spectral response 0.2g, 1-second spectral response 0.084g. Among 147 North Carolina cities in this dataset, Lumberton ranks 31 for seismic hazard, the 79th percentile within the state. About 18,882 people live in Lumberton, North Carolina.

What a retrofit costs in Lumberton

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 Lumberton address.
