Goddard's Seismic Design Category, explained

Under the seismic model IBC and ASCE 7 use for new construction, Goddard is Category B. Low seismic hazard. Code requires basic seismic detailing (bracing, connections) but no special structural system restrictions. Rank it against the rest of the country and Goddard sits at the 24th percentile for seismic hazard among 4,875 US cities.

Where Goddard sits in Kansas

The raw figures: peak ground acceleration 0.044g, short-period spectral response 0.092g, 1-second spectral response 0.054g. Among 63 Kansas cities in this dataset, Goddard ranks 39 for seismic hazard, the 39th percentile within the state. About 6,009 people live in Goddard, Kansas.

Retrofit economics for Goddard

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.

Earthquake insurance for a Goddard home

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 Goddard address.

More on how this number was built

The methodology guide covers exactly how USGS's public design-maps API produced Goddard's numbers. The guide to what a Seismic Design Category actually means covers why a category is never a substitute for an engineer's assessment of one specific house.
