Farmington's Seismic Design Category, explained

Under the seismic model IBC and ASCE 7 use for new construction, Farmington is Category D. High seismic hazard - this is the category most of coastal California, the Pacific Northwest, and other active fault regions fall into. Code mandates significant seismic detailing and restricts irregular structural configurations. This is the category the Brace + Bolt scope (cripple-wall bracing, foundation bolting) is built for. Rank it against the rest of the country and Farmington sits at the 93th percentile for seismic hazard among 4,875 US cities.

Farmington by the numbers

USGS's underlying values for Farmington: 0.61g peak ground acceleration, 1.337g at short period, 0.493g at 1 second. Within Utah alone, Farmington ranks 39 of 95 cities by seismic hazard - the 60th percentile in-state. Farmington has a population of about 26,163.

Retrofit economics for Farmington

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 Utah 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 Utah.

Insuring against this, not just retrofitting

A Farmington 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 Farmington's figures come from

Farmington's Category D 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 D does and doesn't tell you about Farmington.
