Eagle, ID: what USGS's seismic model says

Eagle carries Seismic Design Category C under USGS's ASCE 7-16 model. 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. Nationally, Eagle ranks above 73% of the 4,875 cities in this dataset for seismic hazard - the 73th percentile.

Eagle by the numbers

The raw figures: peak ground acceleration 0.133g, short-period spectral response 0.301g, 1-second spectral response 0.109g. Among 36 Idaho cities in this dataset, Eagle ranks 22 for seismic hazard, the 40th percentile within the state. About 33,451 people live in Eagle, Idaho.

What a retrofit costs in Eagle

Outside California, no state-level retrofit grant equivalent to Brace + Bolt could be found for Idaho. 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 Eagle address.
