De Pere, WI: what USGS's seismic model says

Under the seismic model IBC and ASCE 7 use for new construction, De Pere is Category A. Lowest seismic design category. Building code requires no seismic-specific detailing here beyond ordinary construction practice. Rank it against the rest of the country and De Pere sits at the 7th percentile for seismic hazard among 4,875 US cities.

How De Pere compares

USGS's underlying values for De Pere: 0.024g peak ground acceleration, 0.051g at short period, 0.036g at 1 second. Within Wisconsin alone, De Pere ranks 125 of 157 cities by seismic hazard - the 21th percentile in-state. De Pere has a population of about 25,453.

Retrofit economics for De Pere

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.

Insuring against this, not just retrofitting

A De Pere 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.
