Cultural Resource Reports are often required as part of the Section 106 process.  If you are submitting a Cultural Resource Report, please view our updated Fieldwork Guidelines and Report Guidelines. Both of these guidance documents were updated in October 2021.

Please include the following documents when a report is submitted for review by the State Historic Preservation Office:

1. The following three items should be submitted electronically to Section106@crt.la.gov;

• A cover letter with the project/report title, applicant or client name and address, and the email address and phone number of the person to whom the response letter should be sent.  If the project is being submitted for Section 106 review, please include the name of the appropriate federal agency.  If the report is being submitted for review in advance of any federal agency involvement, the cover letter should specify that the project is being submitted as due diligence.
• A digital pdf copy of the report;
• A copy of the project shapefiles. A kmz or kml file is acceptable. The file must include all of the property in the project area.

2. UPDATE 1/1/2026: We no longer require a hard copies of reports. Our report submission and review process is now completely digital.

(Hard copies are still required for submissions of Site Records and Collections for Curation.)

The National Historic Preservation Act allows the SHPO 30 days from date of receipt of all requested documents to process and provide our response.  We are not able to provide expedited reviews unless a previous legal agreement is in place.  Thank you for your cooperation!
