Walled Lake, MI: what USGS's seismic model says

Walled Lake carries Seismic Design Category B under USGS's ASCE 7-16 model. Low seismic hazard. Code requires basic seismic detailing (bracing, connections) but no special structural system restrictions. Rank it against the rest of the country and Walled Lake sits at the 26th percentile for seismic hazard among 4,875 US cities.

How Walled Lake compares

The raw figures: peak ground acceleration 0.046g, short-period spectral response 0.093g, 1-second spectral response 0.045g. Among 153 Michigan cities in this dataset, Walled Lake ranks 86 for seismic hazard, the 44th percentile within the state. About 7,413 people live in Walled Lake, Michigan.

What a retrofit costs in Walled Lake

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

Earthquake insurance for a Walled Lake 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 Walled Lake address.
