Peekskill's Seismic Design Category, explained

Under the seismic model IBC and ASCE 7 use for new construction, Peekskill is Category B. Low seismic hazard. Code requires basic seismic detailing (bracing, connections) but no special structural system restrictions. That puts Peekskill in the 64th percentile nationally for seismic hazard - higher than 64% of the 4,875 US cities USGS was checked against here.

Where Peekskill sits in New York

The raw figures: peak ground acceleration 0.172g, short-period spectral response 0.281g, 1-second spectral response 0.061g. Among 170 New York cities in this dataset, Peekskill ranks 42 for seismic hazard, the 76th percentile within the state. About 25,757 people live in Peekskill, New York.

Bracing and bolting: the actual cost

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.

Insuring against this, not just retrofitting

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 Peekskill address.

More on how this number was built

The methodology guide covers exactly how USGS's public design-maps API produced Peekskill's numbers. The guide to what a Seismic Design Category actually means covers why a category is never a substitute for an engineer's assessment of one specific house.
