Canby, OR: what USGS's seismic model says

Under the seismic model IBC and ASCE 7 use for new construction, Canby 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. Nationally, Canby ranks above 86% of the 4,875 cities in this dataset for seismic hazard - the 86th percentile.

How Canby compares

USGS's underlying values for Canby: 0.359g peak ground acceleration, 0.791g at short period, 0.368g at 1 second. Within Oregon alone, Canby ranks 51 of 80 cities by seismic hazard - the 37th percentile in-state. Canby has a population of about 18,027.

Bracing and bolting: the actual cost

A full earthquake retrofit typically runs $5,000-$10,000 nationally (around $7,000 typical), driven mainly by house size and foundation type, not by Oregon specifically. California's Earthquake Brace + Bolt grant, which covers a large share of this cost, is a California-only program and does not apply in Oregon.

Insuring against this, not just retrofitting

A Canby homeowner cannot buy a standalone earthquake policy in most cases - it is added to an existing homeowners policy as an endorsement, so the place to start is a regular home-insurance quote.

Where Canby's figures come from

Canby's Category D and every number above trace to USGS's own ASCE 7-16 Design Maps service - see the methodology guide. See the category explainer for what Category D does and doesn't tell you about Canby.
