Fridley, MN: what USGS's seismic model says

Fridley 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. Rank it against the rest of the country and Fridley sits at the 6th percentile for seismic hazard among 4,875 US cities.

How Fridley compares

USGS's underlying values for Fridley: 0.023g peak ground acceleration, 0.048g at short period, 0.029g at 1 second. Within Minnesota alone, Fridley ranks 54 of 155 cities by seismic hazard - the 66th percentile in-state. Fridley has a population of about 30,679.

Retrofit economics for Fridley

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.

Earthquake insurance for a Fridley home

A Fridley 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.
