Watertown, NY: what USGS's seismic model says

USGS's ASCE 7-16 seismic design model - the same standard building codes use - places Watertown in Seismic Design Category B: 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 Watertown sits at the 54th percentile for seismic hazard among 4,875 US cities.

Watertown by the numbers

USGS's underlying values for Watertown: 0.094g peak ground acceleration, 0.183g at short period, 0.061g at 1 second. Within New York alone, Watertown ranks 119 of 170 cities by seismic hazard - the 30th percentile in-state. Watertown has a population of about 24,038.

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.

Insuring against this, not just retrofitting

A Watertown 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 Watertown's figures come from

Watertown'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 Watertown.
