Wenatchee's Seismic Design Category, explained

Wenatchee 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. Rank it against the rest of the country and Wenatchee sits at the 82th percentile for seismic hazard among 4,875 US cities.

Where Wenatchee sits in Washington

USGS's underlying values for Wenatchee: 0.207g peak ground acceleration, 0.468g at short period, 0.191g at 1 second. Within Washington alone, Wenatchee ranks 96 of 125 cities by seismic hazard - the 23th percentile in-state. Wenatchee has a population of about 35,401.

Retrofit economics for Wenatchee

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 Washington 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 Washington.

Earthquake insurance for a Wenatchee home

A Wenatchee 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 Wenatchee's figures come from

Wenatchee'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 Wenatchee.
