Hughson, CA: what USGS's seismic model says

Under the seismic model IBC and ASCE 7 use for new construction, Hughson 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. That puts Hughson in the 84th percentile nationally for seismic hazard - higher than 84% of the 4,875 US cities USGS was checked against here.

How Hughson compares

USGS's underlying values for Hughson: 0.26g peak ground acceleration, 0.622g at short period, 0.253g at 1 second. Within California alone, Hughson ranks 385 of 429 cities by seismic hazard - the 10th percentile in-state. Hughson has a population of about 7,903.

Bracing and bolting: the actual cost

Cripple-wall bracing and foundation bolting - the scope California's Earthquake Brace + Bolt (EBB) grant funds - typically runs $3,000-$7,000 nationally. Every qualifying household gets a $3,000 base grant, which brings that down to $0-$4,000 out of pocket; income-eligible households ($89,040/year or under) can get up to $10,000 total, covering the retrofit outright in most cases.

Earthquake insurance for a Hughson home

Hughson sits in CEA territory, but CEA earthquake coverage is agent-sold only, never direct - so the real first step for a homeowner here is a standard home-insurance quote, then asking that agent about CEA specifically.

Where Hughson's figures come from

Hughson's Category D and every number above trace to USGS's own ASCE 7-16 Design Maps service - see the methodology guide. Full Brace + Bolt eligibility rules - beyond what this page can check from a ZIP code alone - are in the retrofit cost and grant guide.
