Streator, IL: what USGS's seismic model says

USGS's ASCE 7-16 seismic design model - the same standard building codes use - places Streator in Seismic Design Category B: Low seismic hazard. Code requires basic seismic detailing (bracing, connections) but no special structural system restrictions. That puts Streator in the 45th percentile nationally for seismic hazard - higher than 45% of the 4,875 US cities USGS was checked against here.

How Streator compares

The raw figures: peak ground acceleration 0.07g, short-period spectral response 0.141g, 1-second spectral response 0.074g. Among 330 Illinois cities in this dataset, Streator ranks 97 for seismic hazard, the 71th percentile within the state. About 12,295 people live in Streator, Illinois.

Retrofit economics for Streator

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.

What this means for insurance

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 Streator address.
