Does Corrales, NM need an earthquake retrofit?

Corrales 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. Nationally, Corrales ranks above 81% of the 4,875 cities in this dataset for seismic hazard - the 81th percentile.

Corrales by the numbers

USGS's underlying values for Corrales: 0.197g peak ground acceleration, 0.443g at short period, 0.144g at 1 second. Within New Mexico alone, Corrales ranks 5 of 35 cities by seismic hazard - the 88th percentile in-state. Corrales has a population of about 8,530.

What a retrofit costs in Corrales

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 New Mexico 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 New Mexico.

Earthquake insurance for a Corrales home

A Corrales 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.
