Does Edgewater, NJ need an earthquake retrofit?

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

Where Edgewater sits in New Jersey

USGS's underlying values for Edgewater: 0.182g peak ground acceleration, 0.294g at short period, 0.061g at 1 second. Within New Jersey alone, Edgewater ranks 38 of 194 cities by seismic hazard - the 81th percentile in-state. Edgewater has a population of about 15,116.

What a retrofit costs in Edgewater

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 Edgewater 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 Edgewater's figures come from

Edgewater'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 Edgewater.
