Smiths Station's Seismic Design Category, explained

Under the seismic model IBC and ASCE 7 use for new construction, Smiths Station is Category B. Low seismic hazard. Code requires basic seismic detailing (bracing, connections) but no special structural system restrictions. That puts Smiths Station in the 35th percentile nationally for seismic hazard - higher than 35% of the 4,875 US cities USGS was checked against here.

Smiths Station by the numbers

USGS's underlying values for Smiths Station: 0.058g peak ground acceleration, 0.124g at short period, 0.072g at 1 second. Within Alabama alone, Smiths Station ranks 79 of 107 cities by seismic hazard - the 26th percentile in-state. Smiths Station has a population of about 5,583.

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 Alabama 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 Alabama.

Insuring against this, not just retrofitting

A Smiths Station 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 Smiths Station's figures come from

Smiths Station's Category B 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 B does and doesn't tell you about Smiths Station.
