To complete the walkway, we need to put it on the South side of the raised garden. We have it already excavated, walled, and filled with rock on the back side (East), North, and West.
As we excavate the yard, it would be useful to have the South side ready to accep the rocks we dig out.
Also, the South Pit has been excavated and filled back in, so all we have to do is shovel out the dirt and put in the wall. A couple of days of digging gets us almost there.
We need to trim up the dirt next to the South Pit, so that we get a clean vertical wall under the string, which would be 36 inches from the raised garden. Then we can frame it and pour the retaining wall. The retaining wall took 23 bags of Quikrete.
To finish this section of the walkway, we poured the corner that connects the South wall to the West wall.
Using mortar mix to attach the 4x4 chopped/sawed limestone blocks to the top, we have a finished wall separating where the walkway will be from the South bed.
Now all we need to do is fill the walkway area with rubble rock and top it with decomposed granite and flagstones.
