About the CHRIS

The California Historical Resources Information System (CHRIS) consists of the California Office of Historic Preservation (OHP), 10 Information Centers (ICs), and the State Historical Resources Commission (SHRC). The OHP administers and coordinates the CHRIS and presents proposed CHRIS policies to the SHRC, which approves these polices in public meetings. The CHRIS Inventory includes the State Historic Resources Inventory maintained by the OHP as defined in California Public Resources Code § 5020.1(p), and the larger number of resource records and research reports managed under contract by the 10 ICs.

The ICs provide historical resources information, generally on a fee-for-service basis, to local governments, state and federal agencies, Native American tribes, and individuals with responsibilities under the National Environmental Policy Act, the National Historic Preservation Act, and the California Environmental Quality Act (CEQA), as well as to the general public.

Currently, the OHP and the ICs each maintain separate parts of the CHRIS Inventory. The OHP’s portion of the Inventory is forwarded to the ICs according to their county-based service areas so that it can be accessed by CHRIS users. It is statewide in scope, but primarily includes information that has been submitted directly to the OHP. Each of the ICs maintains a part of the CHRIS Inventory that although it is geographically limited to that IC’s service area, includes both information forwarded from the OHP and information that has been submitted directly to that IC by users of the CHRIS. These different parts of the CHRIS Inventory are a combination of paper documents and maps and digital files (whether submitted digitally or converted to that format by the CHRIS). The collective information managed electronically in the CHRIS Inventory is generally referred to as the CHRIS Database.
