Hooper, UT: what USGS's seismic model says

Hooper carries Seismic Design Category D under USGS's ASCE 7-16 model. 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 Hooper sits at the 85th percentile for seismic hazard among 4,875 US cities.

Where Hooper sits in Utah

USGS's underlying values for Hooper: 0.319g peak ground acceleration, 0.732g at short period, 0.266g at 1 second. Within Utah alone, Hooper ranks 79 of 95 cities by seismic hazard - the 17th percentile in-state. Hooper has a population of about 9,548.

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.

What this means for insurance

A Hooper 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.
