Highland Park, IL: what USGS's seismic model says

Highland Park carries Seismic Design Category B under USGS's ASCE 7-16 model. Low seismic hazard. Code requires basic seismic detailing (bracing, connections) but no special structural system restrictions. Nationally, Highland Park ranks above 32% of the 4,875 cities in this dataset for seismic hazard - the 32th percentile.

How Highland Park compares

The raw figures: peak ground acceleration 0.053g, short-period spectral response 0.107g, 1-second spectral response 0.059g. Among 330 Illinois cities in this dataset, Highland Park ranks 291 for seismic hazard, the 12th percentile within the state. About 30,794 people live in Highland Park, Illinois.

Bracing and bolting: the actual cost

Outside California, no state-level retrofit grant equivalent to Brace + Bolt could be found for Illinois. A typical retrofit still runs $5,000-$10,000 nationally, about $7,000 for a common single-family job.

Earthquake insurance for a Highland Park home

Outside California, earthquake coverage is typically sold as an endorsement added to a standard homeowners policy, not a separate product - worth asking about directly when getting a home-insurance quote for a Highland Park address.
