Clinton's Seismic Design Category, explained

Clinton 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 Clinton sits at the 90th percentile for seismic hazard among 4,875 US cities.

Where Clinton sits in Utah

USGS's underlying values for Clinton: 0.487g peak ground acceleration, 1.108g at short period, 0.391g at 1 second. Within Utah alone, Clinton ranks 59 of 95 cities by seismic hazard - the 38th percentile in-state. Clinton has a population of about 23,728.

What a retrofit costs in Clinton

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 Clinton 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 Clinton's figures come from

Clinton'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 Clinton.
