Edina, MN: what USGS's seismic model says

Under the seismic model IBC and ASCE 7 use for new construction, Edina is Category A. Lowest seismic design category. Building code requires no seismic-specific detailing here beyond ordinary construction practice. That puts Edina in the 6th percentile nationally for seismic hazard - higher than 6% of the 4,875 US cities USGS was checked against here.

How Edina compares

USGS's underlying values for Edina: 0.023g peak ground acceleration, 0.048g at short period, 0.03g at 1 second. Within Minnesota alone, Edina ranks 47 of 155 cities by seismic hazard - the 70th percentile in-state. Edina has a population of about 53,564.

What a retrofit costs in Edina

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.

What this means for insurance

A Edina 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 Edina's figures come from

Edina'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 Edina.
