Upper Saddle River's Seismic Design Category, explained

Upper Saddle River 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 Upper Saddle River in the 65th percentile nationally for seismic hazard - higher than 65% of the 4,875 US cities USGS was checked against here.

How Upper Saddle River compares

The raw figures: peak ground acceleration 0.182g, short-period spectral response 0.293g, 1-second spectral response 0.061g. Among 194 New Jersey cities in this dataset, Upper Saddle River ranks 42 for seismic hazard, the 79th percentile within the state. About 8,696 people live in Upper Saddle River, New Jersey.

Retrofit economics for Upper Saddle River

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.

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 Upper Saddle River address.
