Glenview's Seismic Design Category, explained

Under the seismic model IBC and ASCE 7 use for new construction, Glenview is Category B. Low seismic hazard. Code requires basic seismic detailing (bracing, connections) but no special structural system restrictions. That puts Glenview in the 34th percentile nationally for seismic hazard - higher than 34% of the 4,875 US cities USGS was checked against here.

How Glenview compares

USGS's underlying values for Glenview: 0.056g peak ground acceleration, 0.112g at short period, 0.06g at 1 second. Within Illinois alone, Glenview ranks 271 of 330 cities by seismic hazard - the 18th percentile in-state. Glenview has a population of about 47,634.

Retrofit economics for Glenview

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.

Insuring against this, not just retrofitting

A Glenview 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 Glenview's figures come from

Glenview'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 Glenview.
