Alexander City's Seismic Design Category, explained

USGS's ASCE 7-16 seismic design model - the same standard building codes use - places Alexander City in Seismic Design Category B: Low seismic hazard. Code requires basic seismic detailing (bracing, connections) but no special structural system restrictions. That puts Alexander City in the 53th percentile nationally for seismic hazard - higher than 53% of the 4,875 US cities USGS was checked against here.

Where Alexander City sits in Alabama

The raw figures: peak ground acceleration 0.09g, short-period spectral response 0.175g, 1-second spectral response 0.08g. Among 107 Alabama cities in this dataset, Alexander City ranks 66 for seismic hazard, the 39th percentile within the state. About 14,439 people live in Alexander City, Alabama.

Bracing and bolting: the actual cost

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.

Earthquake insurance for a Alexander City home

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 Alexander City address.

More on how this number was built

The methodology guide covers exactly how USGS's public design-maps API produced Alexander City's numbers. The guide to what a Seismic Design Category actually means covers why a category is never a substitute for an engineer's assessment of one specific house.
