Does Redmond, OR need an earthquake retrofit?

Under the seismic model IBC and ASCE 7 use for new construction, Redmond 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, Redmond ranks above 80% of the 4,875 cities in this dataset for seismic hazard - the 80th percentile.

Redmond by the numbers

USGS's underlying values for Redmond: 0.164g peak ground acceleration, 0.361g at short period, 0.187g at 1 second. Within Oregon alone, Redmond ranks 73 of 80 cities by seismic hazard - the 9th percentile in-state. Redmond has a population of about 37,626.

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.

Earthquake insurance for a Redmond home

A Redmond 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 Redmond's figures come from

Redmond'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 Redmond.
