One thing you may consider doing is erecting some basic trellis and growing
a creeper up it. The trellis can be higher than 6 foot and would probably
not constitute a fence if you did it right. You can train a fairly quick
growing creeper up it that require pruning twice a year to keep it neat.

Yes, I've thought about the trellis vs. fence option. I'm not sure what
the criteria are for determining if a trellis constitutes a "fence".
The local code only makes reference to fences.
