Park City, UT: what USGS's seismic model says

Under the seismic model IBC and ASCE 7 use for new construction, Park City is Category D. High seismic hazard - this is the category most of coastal California, the Pacific Northwest, and other active fault regions fall into. Code mandates significant seismic detailing and restricts irregular structural configurations. This is the category the Brace + Bolt scope (cripple-wall bracing, foundation bolting) is built for. Nationally, Park City ranks above 84% of the 4,875 cities in this dataset for seismic hazard - the 84th percentile.

How Park City compares

The raw figures: peak ground acceleration 0.253g, short-period spectral response 0.578g, 1-second spectral response 0.206g. Among 95 Utah cities in this dataset, Park City ranks 85 for seismic hazard, the 11th percentile within the state. About 8,292 people live in Park City, Utah.

What a retrofit costs in Park City

Outside California, no state-level retrofit grant equivalent to Brace + Bolt could be found for Utah. A typical retrofit still runs $5,000-$10,000 nationally, about $7,000 for a common single-family job.

Earthquake insurance for a Park City 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 Park City address.
