Olean's Seismic Design Category, explained

USGS's ASCE 7-16 seismic design model - the same standard building codes use - places Olean in Seismic Design Category A: Lowest seismic design category. Building code requires no seismic-specific detailing here beyond ordinary construction practice. Rank it against the rest of the country and Olean sits at the 15th percentile for seismic hazard among 4,875 US cities.

How Olean compares

USGS's underlying values for Olean: 0.059g peak ground acceleration, 0.116g at short period, 0.04g at 1 second. Within New York alone, Olean ranks 167 of 170 cities by seismic hazard - the 2th percentile in-state. Olean has a population of about 13,614.

What a retrofit costs in Olean

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 Olean 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 Olean's figures come from

Olean's Category A 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 A does and doesn't tell you about Olean.
