We have 3 of the four sides of the raised garden prepared for the walkway, plus the section from the gate to the raised garden. These areas have walls defining the walkway edges, with limestone blocks to give it a finished look. Eventually, we want to put flagstones over them, but that will wait until the entire walkway is finished. We will put the flagstones on a base of decomposed granite over the rubble rock that fills most of the walkway. It seems like a good time to go ahead with the decomposed granite. It will make working in this area much easier.
We bought 3 cubic yards of decomposed granite from Whittlesey Landscape Supplies. To see how large this is, each of the bags below is one yard by one yard by one yard -- a cubic yard. Plus we got a palette of the white limestone 4x4 blocks that we use as edging for our work. We will need them along the walkway, plus all around the yard along the fence.
The cost of this was: decomposed granite $94.35, the limestone blocks $222.60, plus $80 delivery. Including taxes, the total was $435.14.
The rest of this work was fairly simple -- shovel the decomposed granite out of the big white plastic bags, into the wheelbarrow, and then out onto the walkway sections that have been filled with rock rubble.
Hours later, we have the walkways filled in. We have about a half cubic yard more than we needed; it's stored behind the raised garden and we can use it on the section in front of the raised garden, as soon as we have that well-defined and filled in with rock rubble.
And we expect that this will settle, especially if/when we get some rain.
