Ashland's Seismic Design Category, explained

Ashland 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 Ashland sits at the 68th percentile for seismic hazard among 4,875 US cities.

Where Ashland sits in Missouri

The raw figures: peak ground acceleration 0.083g, short-period spectral response 0.174g, 1-second spectral response 0.099g. Among 135 Missouri cities in this dataset, Ashland ranks 86 for seismic hazard, the 37th percentile within the state. About 5,164 people live in Ashland, Missouri.

Bracing and bolting: the actual cost

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.

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 Ashland address.
