Campbell, CA: what USGS's seismic model says

USGS's ASCE 7-16 seismic design model - the same standard building codes use - places Campbell 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 Campbell sits at the 97th percentile for seismic hazard among 4,875 US cities.

Where Campbell sits in California

USGS's underlying values for Campbell: 0.781g peak ground acceleration, 1.896g at short period, 0.674g at 1 second. Within California alone, Campbell ranks 117 of 429 cities by seismic hazard - the 73th percentile in-state. Campbell has a population of about 42,895.

Retrofit economics for Campbell

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.

Insuring against this, not just retrofitting

Campbell 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.
