Ste. Genevieve, MO: what USGS's seismic model says

Ste. Genevieve carries Seismic Design Category D under USGS's ASCE 7-16 model. 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, Ste. Genevieve ranks above 86% of the 4,875 cities in this dataset for seismic hazard - the 86th percentile.

Ste. Genevieve by the numbers

The raw figures: peak ground acceleration 0.348g, short-period spectral response 0.609g, 1-second spectral response 0.216g. Among 135 Missouri cities in this dataset, Ste. Genevieve ranks 9 for seismic hazard, the 94th percentile within the state. About 5,025 people live in Ste. Genevieve, Missouri.

What a retrofit costs in Ste. Genevieve

Outside California, no state-level retrofit grant equivalent to Brace + Bolt could be found for Missouri. 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 Ste. Genevieve address.
