Where Upper Arlington sits in Ohio

USGS's underlying values for Upper Arlington: 0.06g peak ground acceleration, 0.119g at short period, 0.06g at 1 second. Within Ohio alone, Upper Arlington ranks 198 of 254 cities by seismic hazard - the 22th percentile in-state. Upper Arlington has a population of about 36,140.

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 Ohio 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 Ohio.
