Medina's Seismic Design Category, explained

USGS's ASCE 7-16 seismic design model - the same standard building codes use - places Medina in Seismic Design Category A: Lowest seismic design category. Building code requires no seismic-specific detailing here beyond ordinary construction practice. Nationally, Medina ranks above 5% of the 4,875 cities in this dataset for seismic hazard - the 5th percentile.

Medina by the numbers

The raw figures: peak ground acceleration 0.023g, short-period spectral response 0.049g, 1-second spectral response 0.028g. Among 155 Minnesota cities in this dataset, Medina ranks 85 for seismic hazard, the 45th percentile within the state. About 7,209 people live in Medina, Minnesota.

Retrofit economics for Medina

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

Earthquake insurance for a Medina 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 Medina address.
