Woodbury's Seismic Design Category, explained

Under the seismic model IBC and ASCE 7 use for new construction, Woodbury is Category B. Low seismic hazard. Code requires basic seismic detailing (bracing, connections) but no special structural system restrictions. That puts Woodbury in the 55th percentile nationally for seismic hazard - higher than 55% of the 4,875 US cities USGS was checked against here.

Woodbury by the numbers

The raw figures: peak ground acceleration 0.096g, short-period spectral response 0.174g, 1-second spectral response 0.046g. Among 194 New Jersey cities in this dataset, Woodbury ranks 167 for seismic hazard, the 14th percentile within the state. About 10,138 people live in Woodbury, New Jersey.

What a retrofit costs in Woodbury

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 Woodbury 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 Woodbury address.
