Deer Park, WA: what USGS's seismic model says

USGS's ASCE 7-16 seismic design model - the same standard building codes use - places Deer Park in Seismic Design Category C: Moderate seismic hazard. Code adds irregular-building restrictions and requires bracing of some nonstructural components (e.g. tall shelving, water heaters) in addition to structural detailing. That puts Deer Park in the 74th percentile nationally for seismic hazard - higher than 74% of the 4,875 US cities USGS was checked against here.

Where Deer Park sits in Washington

The raw figures: peak ground acceleration 0.14g, short-period spectral response 0.313g, 1-second spectral response 0.113g. Among 125 Washington cities in this dataset, Deer Park ranks 118 for seismic hazard, the 6th percentile within the state. About 5,191 people live in Deer Park, Washington.

Retrofit economics for Deer Park

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.

What this means for insurance

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 Deer Park address.
