Submission guidance

Our office has a 30-day review period from the date of receipt of each submission. If additional information is requested, a new 30-day review period begins from the date of receipt of the new information. You must provide all the required information requested to allow for timely review.

Since the start of the COVID-19 pandemic, DHPA now accepts electronic submissions as an alternative to hard copy submissions.

Hard copy submissions should be mailed to:

Indiana DNR – Division of Historic Preservation & Archaeology
402 W. Washington Street, Room W274
Indianapolis, Indiana 46204.

Electronic submissions should be emailed to:

Electronic submissions should contain the appropriate form(s), and attached documents, including reports, photographs, and plans that must be in Portable Document Format (PDF). Please do not send each photograph as a separate email.

Please note there is a 30MB size limit per email. If necessary, split your submission into multiple emails, indicate in the subject line: 1 of 2, 2 of 3, etc. If the collective review materials are too large to email, use the hard copy option.

If an archaeological investigation has been conducted for the project, the resulting report and site forms (if applicable) must be submitted in the State Historic Architectural and Archaeological Research Database (SHAARD) by the qualified archaeologist. DO NOT send the archaeology report with the remainder of the submission to the DHPA review email; however, you can list the SHAARD report number (i.e., AR-xx-xxxxx) on the Review Request Submittal Form.

Historic Properties are often recorded in accordance with the DHPA Minimum Architectural Documentation Standards when a project will unavoidably alter, demolish, or remove an historic structure, as one aspect of the mitigation.
