Canton's Seismic Design Category, explained

Under the seismic model IBC and ASCE 7 use for new construction, Canton is Category B. Low seismic hazard. Code requires basic seismic detailing (bracing, connections) but no special structural system restrictions. Nationally, Canton ranks above 39% of the 4,875 cities in this dataset for seismic hazard - the 39th percentile.

Canton by the numbers

USGS's underlying values for Canton: 0.062g peak ground acceleration, 0.13g at short period, 0.078g at 1 second. Within Illinois alone, Canton ranks 209 of 330 cities by seismic hazard - the 37th percentile in-state. Canton has a population of about 12,896.

What a retrofit costs in Canton

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 Illinois 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 Illinois.

What this means for insurance

A Canton 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 Canton's figures come from

Canton's Category B 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 B does and doesn't tell you about Canton.
