San Joaquin County Sheriff's Office

San Joaquin County Sheriff’s Office leads what its own documents call a ‘Public Safety Data Exchange Consortium’ — making it one of the few agencies that openly uses the PSDEX name in its contracting documents.

The arrangement covers the entire county: the consortium is designed to include ‘all cities within the County and the San Joaquin County District Attorney.’ That means data from agencies serving Stockton, Manteca, Tracy, Lodi, Ripon, and Escalon — as well as the DA’s office — is intended to flow into the system. The Sheriff’s Office has used the Accurint Virtual Crime Center since 2021, and formalized the county-wide consortium through a five-year agreement running from February 2024 through January 2029.

The data types contributed are broad: computer-aided dispatch records, records management system data, and jail booking data. The county pays approximately $40,000 to $50,000 per year for the lead agency subscription, with individual city agencies paying smaller pro-rated amounts based on sworn officer count. Year one was covered by a federal Homeland Security grant.

This was confirmed through a Lathrop City Council staff report from February 2024, which described the agreement in detail when the city voted to join the consortium. Lathrop — a city of about 28,000 people — is the only confirmed sub-agency so far, though the consortium’s stated scope covers the entire county. California’s SB54 sanctuary law applies throughout San Joaquin County.
