Lake Grove, NY: what USGS's seismic model says

Lake Grove 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. Rank it against the rest of the country and Lake Grove sits at the 58th percentile for seismic hazard among 4,875 US cities.

Lake Grove by the numbers

USGS's underlying values for Lake Grove: 0.111g peak ground acceleration, 0.197g at short period, 0.051g at 1 second. Within New York alone, Lake Grove ranks 97 of 170 cities by seismic hazard - the 43th percentile in-state. Lake Grove has a population of about 11,109.

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 York 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 York.

What this means for insurance

A Lake Grove 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 Lake Grove's figures come from

Lake Grove'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 Lake Grove.
