Hueytown, AL: what USGS's seismic model says

USGS's ASCE 7-16 seismic design model - the same standard building codes use - places Hueytown in Seismic Design Category C: 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. Rank it against the rest of the country and Hueytown sits at the 77th percentile for seismic hazard among 4,875 US cities.

How Hueytown compares

USGS's underlying values for Hueytown: 0.187g peak ground acceleration, 0.313g at short period, 0.103g at 1 second. Within Alabama alone, Hueytown ranks 8 of 107 cities by seismic hazard - the 93th percentile in-state. Hueytown has a population of about 16,185.

Retrofit economics for Hueytown

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 Hueytown 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.
