Liberty's Seismic Design Category, explained

Liberty 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 Liberty sits at the 49th percentile for seismic hazard among 4,875 US cities.

Where Liberty sits in New York

USGS's underlying values for Liberty: 0.077g peak ground acceleration, 0.149g at short period, 0.05g at 1 second. Within New York alone, Liberty ranks 143 of 170 cities by seismic hazard - the 16th percentile in-state. Liberty has a population of about 5,136.

What a retrofit costs in Liberty

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.

Earthquake insurance for a Liberty home

A Liberty 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 Liberty's figures come from

Liberty'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 Liberty.
