Reedsburg's Seismic Design Category, explained

USGS's ASCE 7-16 seismic design model - the same standard building codes use - places Reedsburg in Seismic Design Category B: Low seismic hazard. Code requires basic seismic detailing (bracing, connections) but no special structural system restrictions. That puts Reedsburg in the 16th percentile nationally for seismic hazard - higher than 16% of the 4,875 US cities USGS was checked against here.

How Reedsburg compares

The raw figures: peak ground acceleration 0.029g, short-period spectral response 0.061g, 1-second spectral response 0.043g. Among 157 Wisconsin cities in this dataset, Reedsburg ranks 95 for seismic hazard, the 40th percentile within the state. About 10,314 people live in Reedsburg, Wisconsin.

Bracing and bolting: the actual cost

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.

Earthquake insurance for a Reedsburg 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 Reedsburg address.
