Livingston, MT: what USGS's seismic model says

Livingston carries Seismic Design Category D under USGS's ASCE 7-16 model. High seismic hazard - this is the category most of coastal California, the Pacific Northwest, and other active fault regions fall into. Code mandates significant seismic detailing and restricts irregular structural configurations. This is the category the Brace + Bolt scope (cripple-wall bracing, foundation bolting) is built for. That puts Livingston in the 83th percentile nationally for seismic hazard - higher than 83% of the 4,875 US cities USGS was checked against here.

Livingston by the numbers

USGS's underlying values for Livingston: 0.241g peak ground acceleration, 0.542g at short period, 0.182g at 1 second. Within Montana alone, Livingston ranks 7 of 19 cities by seismic hazard - the 67th percentile in-state. Livingston has a population of about 9,021.

What a retrofit costs in Livingston

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 Montana 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 Montana.

What this means for insurance

A Livingston 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.

Where Livingston's figures come from

Livingston's Category D and every number above trace to USGS's own ASCE 7-16 Design Maps service - see the methodology guide. See the category explainer for what Category D does and doesn't tell you about Livingston.
