Pewaukee, WI: what USGS's seismic model says

Pewaukee carries Seismic Design Category B under USGS's ASCE 7-16 model. Low seismic hazard. Code requires basic seismic detailing (bracing, connections) but no special structural system restrictions. Nationally, Pewaukee ranks above 19% of the 4,875 cities in this dataset for seismic hazard - the 19th percentile.

Pewaukee by the numbers

The raw figures: peak ground acceleration 0.036g, short-period spectral response 0.075g, 1-second spectral response 0.048g. Among 157 Wisconsin cities in this dataset, Pewaukee ranks 55 for seismic hazard, the 65th percentile within the state. About 16,437 people live in Pewaukee, Wisconsin.

Retrofit economics for Pewaukee

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 Pewaukee address.
