El Paso de Robles (Paso Robles), CA: what USGS's seismic model says

USGS's ASCE 7-16 seismic design model - the same standard building codes use - places El Paso de Robles (Paso Robles) 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 El Paso de Robles (Paso Robles) sits at the 90th percentile for seismic hazard among 4,875 US cities.

El Paso de Robles (Paso Robles) by the numbers

The raw figures: peak ground acceleration 0.488g, short-period spectral response 1.164g, 1-second spectral response 0.424g. Among 429 California cities in this dataset, El Paso de Robles (Paso Robles) ranks 314 for seismic hazard, the 27th percentile within the state. About 31,568 people live in El Paso de Robles (Paso Robles), California.

Retrofit economics for El Paso de Robles (Paso Robles)

Because El Paso de Robles (Paso Robles) is in California, the EBB grant applies if the ZIP code participates and the house qualifies (wood-framed house on a raised (not slab-on-grade) foundation, built before 1980): a $3,000-$7,000 bracing-and-bolting job drops to $0-$4,000 after the $3,000 base grant, or effectively free for income-eligible households getting the full $10,000.

Insuring against this, not just retrofitting

Earthquake coverage in California mostly runs through the California Earthquake Authority (CEA), sold only through licensed agents at CEA-participating insurers - there is no direct-to-consumer CEA policy. A general home-insurance quote is the practical starting point for a El Paso de Robles (Paso Robles) homeowner asking about it.
