Oneonta's Seismic Design Category, explained

Oneonta carries Seismic Design Category C under USGS's ASCE 7-16 model. Moderate seismic hazard. Code adds irregular-building restrictions and requires bracing of some nonstructural components (e.g. tall shelving, water heaters) in addition to structural detailing. That puts Oneonta in the 74th percentile nationally for seismic hazard - higher than 74% of the 4,875 US cities USGS was checked against here.

Where Oneonta sits in Alabama

The raw figures: peak ground acceleration 0.144g, short-period spectral response 0.262g, 1-second spectral response 0.103g. Among 107 Alabama cities in this dataset, Oneonta ranks 50 for seismic hazard, the 54th percentile within the state. About 7,039 people live in Oneonta, Alabama.

What a retrofit costs in Oneonta

Outside California, no state-level retrofit grant equivalent to Brace + Bolt could be found for Alabama. A typical retrofit still runs $5,000-$10,000 nationally, about $7,000 for a common single-family job.

Insuring against this, not just retrofitting

Outside California, earthquake coverage is typically sold as an endorsement added to a standard homeowners policy, not a separate product - worth asking about directly when getting a home-insurance quote for a Oneonta address.

More on how this number was built
