New Cumberland's Seismic Design Category, explained

USGS's ASCE 7-16 seismic design model - the same standard building codes use - places New Cumberland in Seismic Design Category B: Low seismic hazard. Code requires basic seismic detailing (bracing, connections) but no special structural system restrictions. Nationally, New Cumberland ranks above 47% of the 4,875 cities in this dataset for seismic hazard - the 47th percentile.

New Cumberland by the numbers

The raw figures: peak ground acceleration 0.073g, short-period spectral response 0.139g, 1-second spectral response 0.043g. Among 193 Pennsylvania cities in this dataset, New Cumberland ranks 74 for seismic hazard, the 62th percentile within the state. About 7,625 people live in New Cumberland, Pennsylvania.

What a retrofit costs in New Cumberland

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

Earthquake insurance for a New Cumberland 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 New Cumberland address.
