Does Wynne, AR need an earthquake retrofit?

Wynne 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. Rank it against the rest of the country and Wynne sits at the 95th percentile for seismic hazard among 4,875 US cities.

Wynne by the numbers

USGS's underlying values for Wynne: 0.69g peak ground acceleration, 1.137g at short period, 0.396g at 1 second. Within Arkansas alone, Wynne ranks 6 of 68 cities by seismic hazard - the 93th percentile in-state. Wynne has a population of about 7,905.

What a retrofit costs in Wynne

A full earthquake retrofit typically runs $5,000-$10,000 nationally (around $7,000 typical), driven mainly by house size and foundation type, not by Arkansas specifically. California's Earthquake Brace + Bolt grant, which covers a large share of this cost, is a California-only program and does not apply in Arkansas.

What this means for insurance

A Wynne homeowner cannot buy a standalone earthquake policy in most cases - it is added to an existing homeowners policy as an endorsement, so the place to start is a regular home-insurance quote.

Where Wynne's figures come from

Wynne's Category D and every number above trace to USGS's own ASCE 7-16 Design Maps service - see the methodology guide. See the category explainer for what Category D does and doesn't tell you about Wynne.
