During the week of August 11, 2025, we performed a self-initiated audit at the Santa Clarita Processing and Distribution Center (P&DC) and four delivery units serviced by the plant. The delivery units included the Chandler Station, Encino and Sherman Oaks Branches, and Woodland Hills Main Post Office in the Los Angeles, CA, area.
We issued individual reports for the four delivery units and P&DC. We also issued another report summarizing the results of our audits at all four delivery units with specific recommendations for management to address.
The audit team identified deficiencies in five areas we reviewed affecting mail delivery and property conditions at the delivery units.
