Lenexa, KS: what USGS's seismic model says

USGS's ASCE 7-16 seismic design model - the same standard building codes use - places Lenexa in Seismic Design 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 Lenexa sits at the 26th percentile for seismic hazard among 4,875 US cities.

How Lenexa compares

The raw figures: peak ground acceleration 0.045g, short-period spectral response 0.095g, 1-second spectral response 0.069g. Among 63 Kansas cities in this dataset, Lenexa ranks 18 for seismic hazard, the 73th percentile within the state. About 59,427 people live in Lenexa, Kansas.

Retrofit economics for Lenexa

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 Lenexa 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 Lenexa address.
