Background

The U.S. Postal Service’s mission is to provide timely, reliable, secure, and affordable mail and package delivery to more than 160 million residential and business addresses across the country. The U.S. Postal Service Office of Inspector General (OIG) reviews delivery operations at facilities across the country and provides management with timely feedback in furtherance of this mission.

This interim report presents the results of our selfinitiated audit of delivery operations and property conditions at the Woodland Hills MPO in Woodland Hills, CA (Project Number 25-124-4). The Woodland Hills MPO is in the California 3 District of the WestPac Area and serves about 98,839 people in ZIP Codes 91302, 91364, 91367, and 91371, which are considered a predominantly urban area (see Figure 1). Specifically, 96,199 (97 percent) live in urban communities and 2,640 (3 percent) live in rural communities. The unit also services ZIP Code 91365 for PO Box routes.

This delivery unit has 72 city routes and six rural routes. From June 14 through July 11, 2025, the delivery unit had six supervisors assigned, including one Relief Supervisor. Of these supervisors, during the week of our visit one was on leave, and one was on a short-term detail to a different facility, but the unit had a supervisor from another facility as a replacement. Thus, at the time of our visit, the unit had five supervisors that reported to work. As of July 11, 2025, the year-to-date employee availability rate for the Woodland Hills MPO was 93.5 percent, which is slightly under the Postal Service’s retail and delivery operations employee availability goal of 93.7 percent for fiscal year 2025. The Woodland Hills MPO is one of four delivery units the OIG reviewed during the week of August 11, 2025, that are serviced by the Santa Clarita Processing and Distribution Center (P&DC).
