Kenmore, WA: what USGS's seismic model says

USGS's ASCE 7-16 seismic design model - the same standard building codes use - places Kenmore in Seismic Design 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, Kenmore ranks above 91% of the 4,875 cities in this dataset for seismic hazard - the 91th percentile.

Kenmore by the numbers

The raw figures: peak ground acceleration 0.537g, short-period spectral response 1.263g, 1-second spectral response 0.442g. Among 125 Washington cities in this dataset, Kenmore ranks 42 for seismic hazard, the 67th percentile within the state. About 24,166 people live in Kenmore, Washington.

Bracing and bolting: the actual cost

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 Kenmore 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 Kenmore address.
