New Richmond, WI: what USGS's seismic model says

Under the seismic model IBC and ASCE 7 use for new construction, New Richmond is Category A. Lowest seismic design category. Building code requires no seismic-specific detailing here beyond ordinary construction practice. That puts New Richmond in the 2th percentile nationally for seismic hazard - higher than 2% of the 4,875 US cities USGS was checked against here.

New Richmond by the numbers

The raw figures: peak ground acceleration 0.021g, short-period spectral response 0.045g, 1-second spectral response 0.029g. Among 157 Wisconsin cities in this dataset, New Richmond ranks 153 for seismic hazard, the 3th percentile within the state. About 10,879 people live in New Richmond, Wisconsin.

Retrofit economics for New Richmond

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

What this means for insurance

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 New Richmond address.
