Abstract

The purpose of this report is to provide a compilation of structural retrofits and replacements of older buildings and infrastructure in the San Francisco Bay Area that have either been completed since 1989 or that are in progress as of October 2018. For the purposes of this report, all or parts of nine Bay Area counties were included: Alameda, Contra Costa, Marin, Napa, San Francisco, San Mateo, Santa Clara, Solano, and Sonoma. Santa Cruz County was not included. The compilation of 700 investments is presented as a table in the appendix. We consider this table as version 1, as we urge that those familiar with additional projects contact the report authors with information to update the table.

In total, we have identified \$73 to \$80 billion in investments to retrofit or replace structures to mitigate the impacts of future San Francisco Bay Area earthquakes. These totals represent an average investment of \$2.5 to \$2.8 billion per year in retrofits and replacement of structures since 1989.
