Bridgeton's Seismic Design Category, explained

Bridgeton 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. Nationally, Bridgeton ranks above 50% of the 4,875 cities in this dataset for seismic hazard - the 50th percentile.

How Bridgeton compares

USGS's underlying values for Bridgeton: 0.078g peak ground acceleration, 0.146g at short period, 0.043g at 1 second. Within New Jersey alone, Bridgeton ranks 181 of 194 cities by seismic hazard - the 7th percentile in-state. Bridgeton has a population of about 27,722.

Bracing and bolting: the actual cost

A full earthquake retrofit typically runs $5,000-$10,000 nationally (around $7,000 typical), driven mainly by house size and foundation type, not by New Jersey specifically. California's Earthquake Brace + Bolt grant, which covers a large share of this cost, is a California-only program and does not apply in New Jersey.

What this means for insurance

A Bridgeton homeowner cannot buy a standalone earthquake policy in most cases - it is added to an existing homeowners policy as an endorsement, so the place to start is a regular home-insurance quote.

Where Bridgeton's figures come from

Bridgeton's Category B and every number above trace to USGS's own ASCE 7-16 Design Maps service - see the methodology guide. See the category explainer for what Category B does and doesn't tell you about Bridgeton.
