Enoch, UT: what USGS's seismic model says

USGS's ASCE 7-16 seismic design model - the same standard building codes use - places Enoch in Seismic Design 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 Enoch sits at the 86th percentile for seismic hazard among 4,875 US cities.

Enoch by the numbers

USGS's underlying values for Enoch: 0.337g peak ground acceleration, 0.764g at short period, 0.245g at 1 second. Within Utah alone, Enoch ranks 76 of 95 cities by seismic hazard - the 20th percentile in-state. Enoch has a population of about 8,664.

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 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.

Earthquake insurance for a Enoch home

A Enoch 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 Enoch's figures come from

Enoch'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 Enoch.
