Flushing, MI: what USGS's seismic model says
Flushing 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. That puts Flushing in the 13th percentile nationally for seismic hazard - higher than 13% of the 4,875 US cities USGS was checked against here.
How Flushing compares
USGS's underlying values for Flushing: 0.037g peak ground acceleration, 0.078g at short period, 0.042g at 1 second. Within Michigan alone, Flushing ranks 130 of 153 cities by seismic hazard - the 15th percentile in-state. Flushing has a population of about 8,224.
What a retrofit costs in Flushing
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 Michigan 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 Michigan.
Insuring against this, not just retrofitting
A Flushing 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 Flushing's figures come from
Flushing'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 Flushing.
