Does Safford, AZ need an earthquake retrofit?

Safford carries Seismic Design Category B under USGS's ASCE 7-16 model. Low seismic hazard. Code requires basic seismic detailing (bracing, connections) but no special structural system restrictions. That puts Safford in the 58th percentile nationally for seismic hazard - higher than 58% of the 4,875 US cities USGS was checked against here.

How Safford compares

USGS's underlying values for Safford: 0.112g peak ground acceleration, 0.253g at short period, 0.08g at 1 second. Within Arizona alone, Safford ranks 25 of 57 cities by seismic hazard - the 57th percentile in-state. Safford has a population of about 10,257.

Retrofit economics for Safford

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 Arizona 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 Arizona.

Insuring against this, not just retrofitting

A Safford 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 Safford's figures come from

Safford's Category B 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 B does and doesn't tell you about Safford.
