Cultural Resource Protection: Submitting a Project for Review

The Cultural Resource Protection program within the Illinois State Historic Preservation Office (SHPO) uses a digital submission and review process. We do not accept hardcopy submissions of Regulatory projects. Click here for instructions on how to check the status of our review of your projects.

  • If your project involves small-cell antennae installation, click here.
  • If your project is a Wind Farm (4 or more turbines), click here.

For all other undertakings subject to review under Section 106 (federal) or Section 707 (state), please follow these instructions. If you have questions about how to submit your undertaking, please email us at

Individual undertakings must be submitted separately. Undertakings with multiple addresses but the same scope of work may be submitted together.   

Electronic submission:

If your submission is larger than 30 MB in total size:

Cover letter

The cover letter must be on your organization's letterhead and include the following information:

  1. Project's county, street address, and municipality. If no street address is available, please provide nearest street, section, township, and range. For unincorporated areas, please provide the nearest municipality and county.
  2. Complete description of your project, including any proposed ground-disturbing activity
  3. Names of state and/or federal agencies and entities that are providing funding, licenses, permits, or approvals for your project
  4. Name, email address, phone, and mailing address of the project contact
  5. Previously assigned SHPO log numbers associated with your project (if any)
  6. Total acreage involved in the project
  7. Year of original construction for each structure on the project site
  8. Description of any prior non-agricultural ground disturbance in the project area
  9. Any known historical information, architectural significance, significance to community, or association with a significant individual for any cultural resources within the project area

Maps & Images

  1. Map showing your project's location
  2. For projects that propose ground disturbance, provide both a USGS 7.5-minute topographic map and recent aerial imagery with the project limits clearly indicated
  3. Color photos taken within the past 6-to-9 months of all structures in the project area or Area of Potential Effect, preferably without foliage blocking the view. Photos should show the buildings' exterior and front elevations. If clear images cannot be obtained because of right-of-way issues, submit the best photo available, and include an explanation. Images must be appropriately named, high-resolution ".jpg" or ".pdf" files.  Image files with the ".heic" extension will not be accepted
  4. Representative interior photos of any structures over 40 years of age
  5. High-resolution digital scans of relevant historic photographs and previous architectural plans (if applicable/available)

Architectural/engineering plans and specifications

If architectural or engineering plans and specifications have been prepared, please submit them. We would like to review your project as early in your planning process as we can. If you have only schematic or diagrammatic plans, please submit them.  If you don't yet have architectural or engineering plans and if we need to review them, we will request that you submit them to us when they are developed.

Archaeological survey, testing, or mitigation reports

Any archaeological survey, testing, or mitigation reports associated with the project, along with GIS files (ESRI or Google Earth polygons) of the survey coverage, must be submitted digitally. GIS files of survey coverages only should be submitted to Miranda Yancey at following submission of the report to SHPO, if they were not already submitted to obtain site numbers. Feel free to use our standard Archaeological Survey Short Report (ASSR). If you opt to not use the ASSR format, your report must be accompanied by the Archaeological Report Summary form.
