Rothschild's Seismic Design Category, explained

Rothschild carries Seismic Design Category A under USGS's ASCE 7-16 model. Lowest seismic design category. Building code requires no seismic-specific detailing here beyond ordinary construction practice. Nationally, Rothschild ranks above 3% of the 4,875 cities in this dataset for seismic hazard - the 3th percentile.

How Rothschild compares

USGS's underlying values for Rothschild: 0.022g peak ground acceleration, 0.047g at short period, 0.033g at 1 second. Within Wisconsin alone, Rothschild ranks 152 of 157 cities by seismic hazard - the 3th percentile in-state. Rothschild has a population of about 5,629.

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 Wisconsin 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 Wisconsin.

What this means for insurance

A Rothschild 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.

Where Rothschild's figures come from

Rothschild's Category A and every number above trace to USGS's own ASCE 7-16 Design Maps service - see the methodology guide. See the category explainer for what Category A does and doesn't tell you about Rothschild.
