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.
Wind Farm projects in Illinois are reviewable under Section 106 of the National Historic Preservation Act or under the Illinois State Agency Historic Resource Preservation Act, depending on which state or federal action they require.

- Compress or "zip" the folder (information from
Microsoft regarding zipping files)
- Upload the zipped folder to:
https://filet.illinois.gov/filet/PIMupload.asp, and enter "SHPO.Review@Illinois.gov" as the recipient

(click here to expand/collapse requirements)
- Map or maps showing your proposed Wind Farm's location and general boundary
- Map or maps showing your Wind Farm's Areas of Potential Effect (APEs) and the location of every numbered structure surveyed in the Architectural Resources Survey, described below. The radius of the APE around each turbine increases with the height of the turbine. Turbines that are 200 to 400 feet tall to the tip of the blade have an APE with a radius of 0.75 miles. Turbine that are 400 to 600 feet tall to the tip of the blade have an APE with a radius of 1.5 miles.
Architectural Resources Survey
(click here to expand/collapse requirements)
Each structure within the Wind Farm's APEs must be surveyed and must have its own record within the Survey that contains the following information:
- A unique number that you or your consultant assigns to that structure. This number must be shown with its location on the map described in #2 in the Map section above.
- Its full address
- Distance from the turbines in whose APEs it is located
- Any previous determinations of eligibility for listing on the National Register of Historic Places.
- Color photos taken within the past 6-to-9 months, preferably without foliage blocking the view. Photos should show the building's exterior and front elevation. If clear images cannot be obtained because of right-of-way issues, submit the best photos 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.
- Year of construction
- Any known historical information, architectural significance, significance to community, or association with a significant individual
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. 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. One (1) hardcopy report, project cover letter, and Archaeological Report Summary form (if applicable), must be mailed to:
