Woodcliff Lake, NJ: what USGS's seismic model says

USGS's ASCE 7-16 seismic design model - the same standard building codes use - places Woodcliff Lake in Seismic Design Category B: Low seismic hazard. Code requires basic seismic detailing (bracing, connections) but no special structural system restrictions. That puts Woodcliff Lake in the 66th percentile nationally for seismic hazard - higher than 66% of the 4,875 US cities USGS was checked against here.

Woodcliff Lake by the numbers

The raw figures: peak ground acceleration 0.184g, short-period spectral response 0.296g, 1-second spectral response 0.061g. Among 194 New Jersey cities in this dataset, Woodcliff Lake ranks 23 for seismic hazard, the 89th percentile within the state. About 6,234 people live in Woodcliff Lake, New Jersey.

Retrofit economics for Woodcliff Lake

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

Earthquake insurance for a Woodcliff Lake 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 Woodcliff Lake address.
