Orland's Seismic Design Category, explained

Orland 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. That puts Orland in the 87th percentile nationally for seismic hazard - higher than 87% of the 4,875 US cities USGS was checked against here.

Where Orland sits in California

USGS's underlying values for Orland: 0.373g peak ground acceleration, 0.841g at short period, 0.354g at 1 second. Within California alone, Orland ranks 350 of 429 cities by seismic hazard - the 18th percentile in-state. Orland has a population of about 8,605.

Retrofit economics for Orland

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

Orland 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 Orland's figures come from

Orland'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.
