Does Park City, KS need an earthquake retrofit?

Under the seismic model IBC and ASCE 7 use for new construction, Park City is Category B. Low seismic hazard. Code requires basic seismic detailing (bracing, connections) but no special structural system restrictions. That puts Park City in the 21th percentile nationally for seismic hazard - higher than 21% of the 4,875 US cities USGS was checked against here.

Where Park City sits in Kansas

USGS's underlying values for Park City: 0.041g peak ground acceleration, 0.087g at short period, 0.054g at 1 second. Within Kansas alone, Park City ranks 51 of 63 cities by seismic hazard - the 19th percentile in-state. Park City has a population of about 9,110.

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.

Earthquake insurance for a Park City home

A Park City 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.
