Garden City, KS: what USGS's seismic model says

Under the seismic model IBC and ASCE 7 use for new construction, Garden City is Category A. Lowest seismic design category. Building code requires no seismic-specific detailing here beyond ordinary construction practice. Nationally, Garden City ranks above 13% of the 4,875 cities in this dataset for seismic hazard - the 13th percentile.

How Garden City compares

The raw figures: peak ground acceleration 0.036g, short-period spectral response 0.077g, 1-second spectral response 0.039g. Among 63 Kansas cities in this dataset, Garden City ranks 62 for seismic hazard, the 2th percentile within the state. About 27,996 people live in Garden City, Kansas.

Bracing and bolting: the actual cost

Outside California, no state-level retrofit grant equivalent to Brace + Bolt could be found for Kansas. 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 Garden City address.
