Does Basehor, KS need an earthquake retrofit?

Under the seismic model IBC and ASCE 7 use for new construction, Basehor is Category B. Low seismic hazard. Code requires basic seismic detailing (bracing, connections) but no special structural system restrictions. That puts Basehor in the 25th percentile nationally for seismic hazard - higher than 25% of the 4,875 US cities USGS was checked against here.

Where Basehor sits in Kansas

USGS's underlying values for Basehor: 0.045g peak ground acceleration, 0.094g at short period, 0.066g at 1 second. Within Kansas alone, Basehor ranks 28 of 63 cities by seismic hazard - the 56th percentile in-state. Basehor has a population of about 7,996.

Bracing and bolting: the actual cost

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 Kansas 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 Kansas.

Insuring against this, not just retrofitting

A Basehor 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 Basehor's figures come from

Basehor's Category B 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 B does and doesn't tell you about Basehor.
