Lacey, WA: what USGS's seismic model says

USGS's ASCE 7-16 seismic design model - the same standard building codes use - places Lacey in Seismic Design Category D: 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. Rank it against the rest of the country and Lacey sits at the 93th percentile for seismic hazard among 4,875 US cities.

Lacey by the numbers

USGS's underlying values for Lacey: 0.593g peak ground acceleration, 1.385g at short period, 0.505g at 1 second. Within Washington alone, Lacey ranks 20 of 125 cities by seismic hazard - the 85th percentile in-state. Lacey has a population of about 58,644.

Retrofit economics for Lacey

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 Washington 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 Washington.

Insuring against this, not just retrofitting

A Lacey 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.
