Does Beach Park, IL need an earthquake retrofit?

Beach 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. That puts Beach Park in the 28th percentile nationally for seismic hazard - higher than 28% of the 4,875 US cities USGS was checked against here.

Where Beach Park sits in Illinois

The raw figures: peak ground acceleration 0.047g, short-period spectral response 0.096g, 1-second spectral response 0.055g. Among 330 Illinois cities in this dataset, Beach Park ranks 325 for seismic hazard, the 2th percentile within the state. About 14,212 people live in Beach Park, Illinois.

Earthquake insurance for a Beach 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 Beach Park address.
