Greenwood Village's Seismic Design Category, explained

Under the seismic model IBC and ASCE 7 use for new construction, Greenwood Village is Category B. Low seismic hazard. Code requires basic seismic detailing (bracing, connections) but no special structural system restrictions. That puts Greenwood Village in the 59th percentile nationally for seismic hazard - higher than 59% of the 4,875 US cities USGS was checked against here.

Where Greenwood Village sits in Colorado

The raw figures: peak ground acceleration 0.116g, short-period spectral response 0.211g, 1-second spectral response 0.058g. Among 79 Colorado cities in this dataset, Greenwood Village ranks 38 for seismic hazard, the 53th percentile within the state. About 15,288 people live in Greenwood Village, Colorado.

Retrofit economics for Greenwood Village

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

Earthquake insurance for a Greenwood Village 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 Greenwood Village address.
