Bella Vista, AR: what USGS's seismic model says

Bella Vista carries Seismic Design Category C under USGS's ASCE 7-16 model. 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. Rank it against the rest of the country and Bella Vista sits at the 67th percentile for seismic hazard among 4,875 US cities.

How Bella Vista compares

The raw figures: peak ground acceleration 0.07g, short-period spectral response 0.148g, 1-second spectral response 0.088g. Among 68 Arkansas cities in this dataset, Bella Vista ranks 62 for seismic hazard, the 9th percentile within the state. About 33,274 people live in Bella Vista, Arkansas.

Bracing and bolting: the actual cost

Outside California, no state-level retrofit grant equivalent to Brace + Bolt could be found for Arkansas. 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 Bella Vista address.
