The rest of the building is probably newer than the date on the facade. This structure was being renovated at the time of the earthquake. It is likely that the large wooden diagonal bracing in the interior of the building played a role in preventing serious damage to the building. Undamaged retrofitted building in downtown Napa. This building is located on Main street next to the Opera house.
Building appears to have been recently renovated with tubular steel bracing.
One other old URM along main street also had diagonal tension cracking, however other URM buildings appeared undamaged. One would have expected more damage to some of these URM buildings had the motions been more severe. In general, the damage was relatively small. The post office had approximately 14 broken windows along its main facade. Some of these broken windows could have resulted in serious injuries to people inside the post office if the earthquake would have occurred at an hour where the building was in service.
