Does Island Park, NY need an earthquake retrofit?

USGS's ASCE 7-16 seismic design model - the same standard building codes use - places Island Park in Seismic Design Category B: Low seismic hazard. Code requires basic seismic detailing (bracing, connections) but no special structural system restrictions. That puts Island Park in the 62th percentile nationally for seismic hazard - higher than 62% of the 4,875 US cities USGS was checked against here.

Island Park by the numbers

The raw figures: peak ground acceleration 0.151g, short-period spectral response 0.253g, 1-second spectral response 0.056g. Among 170 New York cities in this dataset, Island Park ranks 73 for seismic hazard, the 57th percentile within the state. About 5,019 people live in Island Park, New York.

What a retrofit costs in Island Park

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

Earthquake insurance for a Island 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 Island Park address.
