NWIC

About Us

The Northwest Information Center (NWIC) of the California Historical Resources Information System is one of nine information centers affiliated with the State of California Office of Historic Preservation (OHP) in Sacramento.

Our office is located at 150 Professional Center Drive, Suite E, Rohnert Park, CA 94928.

We are open for in-house research, by appointment only, Mondays through Fridays, from 9:00-4:00.

Contact information for all Information Centers may be found here.

These Information Centers are non-profit organizations located at various universities, museums, and tribal organizations throughout the state of California. Each center serves a specific geographic area within the state. The NWIC service area includes 18 coastal, Bay Area, and inland counties, from the California-Oregon border in the north to Monterey in the south. This area comprises over 15% of the State of California.

The purpose of the center is...

  • to manage cultural resources records, reports, and maps.
  • to supply cultural resources information to the private and public sector (some restrictions do apply.)
  • to provide educational support and information about cultural resources in California to the general public.

Services Offered

NWIC staff regularly assist Cultural Resources Consultants undertaking research in history and archaeology as well as providing information to landowners, scholars, and the general public about archaeology, history, architecture, and cultural resources legislation.

Research and information is provided to more than 100 federal, state, or local government agencies, as well as over one thousand private cultural resource consultants, environmental, planning, engineering, and development firms. Approximately 2000 requests for information are fulfilled each year.

Inventory access, products and services are provided on a fee-for-service basis.

Fees for Inventory Access may be accessed here.

News

NWIC is closed for in-house appointments

Until further notice, the Northwest Information Center will be closed for in-house appointments in accordance with Sonoma County's "shelter-in-place" order that is currently effective through May 3, 2020.

If you need a CHRIS search, however, no worries, we are still open and staff are waiting for your search!

Currently our phone number is not the best manner to reach us, so please send us an email and we will get back to you as soon as possible.

Turnaround times for inventory processing will be affected to some degree but that is not quite clear yet, but all efforts will be made to minimize the impact. Record search turnaround times are still more or less typical. Please reach out to us if you have any questions.

New CHRIS Data Request Form

The new CHRIS Data Request Form is available! For more information, see our Record Searches page.

The Built Environment Resources Directory Update

At the end of 2019, the OHP released an update to the April 2012 Historic Properties Directory. This December 2019 update was provided by the OHP as a spreadsheet, not as a printed output, and given a new name. Moving forward, the directory that is provided by the OHP is to be referred to as the Built Environment Resources Directory. For more details on the BERD, including the new status codes contained within the new directory, feel free to download a copy of the User’s Guide here.

…and the plan is to post it online! Check out the OHP Directories page for more info.

The NWIC uses Google Drive to send your record search results and receive inventory materials. All new accounts are set up in Google Drive.
