I've been here for years, and I have no idea that ^^^ meant that. If anything, I'd have thought that ^ would be the post above, and ^^^ would be 3 posts above. Replying to the post directly above seems reasonable.Its good etiquette when replying to someone to use the reply button to quote the message (or part of the message) you are replying to. Alternatively, if replying to the last post in the thread, you can prefix your post with "^^^" (though you risk someone else posting something before your reply, breaking your reference).
However, pasting the relevant text in, from the 175 page document, or at least the PDF page number - given the text is unsearchable. (it's in Section 12.1 on page 13 of the PDF).
BTW, what kind of hick-town puts the entire council agenda, supporting documents, and attachments in a single, unsearchable (they scanned it for frig's sake!) document? This isn't the 1990's.
