St. Louis Park, MN: what USGS's seismic model says

USGS's ASCE 7-16 seismic design model - the same standard building codes use - places St. Louis Park in Seismic Design Category A: Lowest seismic design category. Building code requires no seismic-specific detailing here beyond ordinary construction practice. Nationally, St. Louis Park ranks above 6% of the 4,875 cities in this dataset for seismic hazard - the 6th percentile.

Where St. Louis Park sits in Minnesota

USGS's underlying values for St. Louis Park: 0.023g peak ground acceleration, 0.048g at short period, 0.029g at 1 second. Within Minnesota alone, St. Louis Park ranks 49 of 155 cities by seismic hazard - the 69th percentile in-state. St. Louis Park has a population of about 49,899.

Retrofit economics for St. Louis Park

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 Minnesota 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 Minnesota.

Insuring against this, not just retrofitting

A St. Louis Park 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.
