County Publishes SB 272 Data System Inventory

Today the Information Services Department (ISD) for the County of San Mateo announced that it had published to its Open Data Portal the data related to County systems as required by California Senate Bill No. 272.

SB-272 The California Public Records Act: local agencies: inventories passed in 2015 and requires local agencies to create and make available online a catalog of enterprise systems effective as of today, July 1, 2016. SB-272 was drafted to enhance government transparency by making local agencies’ data more accessible easier, as well as increase governmental efficiency.

According to the bill, this catalog must be made public upon request and be posted in a prominent location on the local agency’s website. The data inventory can be accessed here:

Systems listed in the catalog include any software application or computer system that collects, stores, exchanges and analyzes information that the agency uses that is both:

  • A multi-departmental system or a system that contains information collected about the public;
  • A system that serves as an original source of data within an agency.

There are some systems not required to be included in the catalog, including certain IT systems related to information security, physical security and employee ID systems, emergency dispatch systems, and a few others.

The data listed in the County's system catalog includes the vendor, product, purpose, data category, custodian department, data collection frequency, and data update frequency.

Open San Mateo County is the place to find data published by the County of San Mateo. Anyone can explore the data and government programs including the Shared Vision 2025 and Measure A dashboards. The Open Data Portal allows citizens to see performance metrics for all activities of the County government as well as consolidate other available data around the County.
