Moncks Corner, SC: what USGS's seismic model says

USGS's ASCE 7-16 seismic design model - the same standard building codes use - places Moncks Corner in Seismic Design Category D: High seismic hazard - this is the category most of coastal California, the Pacific Northwest, and other active fault regions fall into. Code mandates significant seismic detailing and restricts irregular structural configurations. This is the category the Brace + Bolt scope (cripple-wall bracing, foundation bolting) is built for. Nationally, Moncks Corner ranks above 98% of the 4,875 cities in this dataset for seismic hazard - the 98th percentile.

How Moncks Corner compares

The raw figures: peak ground acceleration 0.986g, short-period spectral response 1.531g, 1-second spectral response 0.479g. Among 66 South Carolina cities in this dataset, Moncks Corner ranks 7 for seismic hazard, the 91th percentile within the state. About 18,359 people live in Moncks Corner, South Carolina.

Bracing and bolting: the actual cost

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

Earthquake insurance for a Moncks Corner home

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 Moncks Corner address.
