I created a wireframe in Illustrator. I have it saved as an AI file. I decided to "Save As" a PDF so as to send it to the client. The PDF shows excess footer layers at the bottom. In fact, it replicated my footer two more times. I did not name my layers and I cannot find where to delete this is in the AI file version of the wireframe, because the excess footers do not show up here. Any suggestions on how to fix this?
Each artboard in Illustrator will create a page in a PDF (even if artboards overlap).
It appears as though you have 3 artboards.... one full size, then 2 the size of the footer.
Delete the extra 2 footer artboards and then save as a PDF again, you should have only 1 page. Or you could merely delete the extra 2 pages in the PDF using Acrobat.
