Active Disasters: Immediate Response and Assistance Information
(This link activates when state emergency or federal disaster proclamations are announced for California)
In recognition of the continuing COVID-19 situation, we are providing updated submission guidance to address the challenges agencies may be encountering in sending hard-copy submittals to our office during the statewide stay-at-home order.
Additionally, due to evolving circumstances related to COVID-19 policies at the various universities where CHRIS Information Centers (ICs) are located, IC clients should contact the appropriate IC to inquire as to how to submit records search requests and how and when such requests may be fulfilled.
Finally, we are pleased to announce the launch of the Built Environment Resources Directory (BERD). This online data source lists California properties by county and provides information regarding cultural, non-archaeological resources that have been processed through the OHP. This includes resources reviewed for eligibility to the National Register of Historic Places and the California Historical Landmarks programs through federal and state environmental compliance laws, and resources nominated under federal and state registration programs.
