Hi Dawn: Here is one, hope it's what you're looking for. You must make it as long or short as you want it, there is nothing written in stone (hahaha) about it :) It's a Hometalk project: https://www.hometalk.com/44294519/cinder-block-fence-with-4x4-s Good luck
It looks like you have some great ideas above and here’s some fundamentals if you’re building a new fence:
Pouring a Foundation sized to the height of the wall.
Steel re-bar re-enforcing sized to the height.
Height Allowed is governed by the local city or county. Back yard limit is typically 6’ above grade. Front yard will be much shorter, and that may vary based on how close to it to the front property line.
I thought this looked like an easy and inexpensive project. You just stack the blocks and use boards to attach them.
