Illinois IDOT permit question

Greetings everyone,
Recently closed my first lease signing and I’m moving along with the permit process now.
I’m a new guy to the outdoor biz so I’m really unfamiliar with all the specifics that the Illinois Department of Transportation, or IDOT, is looking for.
In the section marked “Airport Restrictions” there is a line that states "To be completed by Division of Aeronautics"
Do I really have to submit this app to the DA for their approval even if the sign is not within two miles of an airport? I’m assuming that line is nonapplicable but just wanted some feed back.
By the way Frank, I bought your CD’s and have found them to be quite informative.
