Quake Damage Update : Assessment of Valley Destruction Rises By a Third

A new assessment of building inspection records has placed the total earthquake damage to structures in the San Fernando Valley at more $1.22 billion, a jump of 35% from the previously reported figure.

A Times’ computer ZIP code analysis of the new information released by the Los Angeles City Building and Safety Department shows some changes in the quirky distribution of earthquake damage, as reported in a February study.

Shown is a comparison by ZIP code of estimates of the cost to rebuild damaged structures and the number of buildings deemed either unsafe or safe only for limited entry. The largest increase occurred in Northridge (ZIP code 91324), where the estimate of damage more than doubled to $199 million from $97 million in February.

That increase eclipsed Sherman Oaks as the community incurring the most damage in the Jan. 17 earthquake. Still, both Sherman Oaks and Canoga Park had more damage ta several communities closer to the epicenter.

The new estimate largely reflects a refinement of the method of analysis rather than the discovery of new damage, said Times computer analyst Richard O’Reilly.

The earlier toll of $902 million was derived by a computer math of building inspection reports with the Los Angeles County Tax rolls. A percentage of the properties did not match properly. Recently, the Building and Safety Department completed a manual tally of tax assessments for each damaged property.
