Middletown's Seismic Design Category, explained

USGS's ASCE 7-16 seismic design model - the same standard building codes use - places Middletown 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 Middletown sits at the 59th percentile for seismic hazard among 4,875 US cities.

Where Middletown sits in New York

USGS's underlying values for Middletown: 0.117g peak ground acceleration, 0.207g at short period, 0.054g at 1 second. Within New York alone, Middletown ranks 93 of 170 cities by seismic hazard - the 46th percentile in-state. Middletown has a population of about 30,188.

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.

Earthquake insurance for a Middletown home

A Middletown 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 Middletown's figures come from

Middletown'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 Middletown.
