Lyndhurst, OH: what USGS's seismic model says

USGS's ASCE 7-16 seismic design model - the same standard building codes use - places Lyndhurst 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 Lyndhurst sits at the 51th percentile for seismic hazard among 4,875 US cities.

Where Lyndhurst sits in Ohio

USGS's underlying values for Lyndhurst: 0.083g peak ground acceleration, 0.151g at short period, 0.05g at 1 second. Within Ohio alone, Lyndhurst ranks 33 of 254 cities by seismic hazard - the 87th percentile in-state. Lyndhurst has a population of about 13,700.

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.

What this means for insurance

A Lyndhurst 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.
