Does Dana Point, CA need an earthquake retrofit?

Dana Point 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. Nationally, Dana Point ranks above 91% of the 4,875 cities in this dataset for seismic hazard - the 91th percentile.

How Dana Point compares

The raw figures: peak ground acceleration 0.546g, short-period spectral response 1.252g, 1-second spectral response 0.449g. Among 429 California cities in this dataset, Dana Point ranks 279 for seismic hazard, the 35th percentile within the state. About 32,585 people live in Dana Point, California.

What a retrofit costs in Dana Point

Because Dana Point 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 Dana Point homeowner asking about it.
