Federal Heights's Seismic Design Category, explained

Under the seismic model IBC and ASCE 7 use for new construction, Federal Heights is Category B. Low seismic hazard. Code requires basic seismic detailing (bracing, connections) but no special structural system restrictions. Nationally, Federal Heights ranks above 59% of the 4,875 cities in this dataset for seismic hazard - the 59th percentile.

Where Federal Heights sits in Colorado

USGS's underlying values for Federal Heights: 0.114g peak ground acceleration, 0.208g at short period, 0.058g at 1 second. Within Colorado alone, Federal Heights ranks 41 of 79 cities by seismic hazard - the 49th percentile in-state. Federal Heights has a population of about 13,971.

Bracing and bolting: the actual cost

A full earthquake retrofit typically runs $5,000-$10,000 nationally (around $7,000 typical), driven mainly by house size and foundation type, not by Colorado specifically. California's Earthquake Brace + Bolt grant, which covers a large share of this cost, is a California-only program and does not apply in Colorado.

Earthquake insurance for a Federal Heights home

A Federal Heights homeowner cannot buy a standalone earthquake policy in most cases - it is added to an existing homeowners policy as an endorsement, so the place to start is a regular home-insurance quote.
