North Bend, WA: what USGS's seismic model says

North Bend 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 North Bend in the 89th percentile nationally for seismic hazard - higher than 89% of the 4,875 US cities USGS was checked against here.

How North Bend compares

The raw figures: peak ground acceleration 0.474g, short-period spectral response 1.11g, 1-second spectral response 0.385g. Among 125 Washington cities in this dataset, North Bend ranks 74 for seismic hazard, the 41th percentile within the state. About 8,553 people live in North Bend, Washington.

Retrofit economics for North Bend

Outside California, no state-level retrofit grant equivalent to Brace + Bolt could be found for Washington. A typical retrofit still runs $5,000-$10,000 nationally, about $7,000 for a common single-family job.

Earthquake insurance for a North Bend home

Outside California, earthquake coverage is typically sold as an endorsement added to a standard homeowners policy, not a separate product - worth asking about directly when getting a home-insurance quote for a North Bend address.
