Does Somers Point, NJ need an earthquake retrofit?

Somers Point carries Seismic Design Category A under USGS's ASCE 7-16 model. Lowest seismic design category. Building code requires no seismic-specific detailing here beyond ordinary construction practice. That puts Somers Point in the 15th percentile nationally for seismic hazard - higher than 15% of the 4,875 US cities USGS was checked against here.

Where Somers Point sits in New Jersey

USGS's underlying values for Somers Point: 0.061g peak ground acceleration, 0.12g at short period, 0.04g at 1 second. Within New Jersey alone, Somers Point ranks 190 of 194 cities by seismic hazard - the 2th percentile in-state. Somers Point has a population of about 10,611.

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.

Insuring against this, not just retrofitting

A Somers Point 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.
