I had an intern today do a rough volume measurement to calculate the amount of pebble stone to buy, and I was surprised by the result. The walkway is about 160 feet long, and varies between 3 feet and 8 feet wide, probably averaging about five feet. If we lay down under two inches of pebble stone, we calculated that we would need about 223 cubic feet of material, which we calculated based on weight and volume of the pebblestone to be about 13K pounds of stone, a little over six metric tons.
That strikes me as a lot of stone. Does this sound ballpark correct for the amount of space described here? This assumed we pretty much covered all of the walkway space with pebble stone that is about two inches deep. After seeing the amount of stone here, I'm ready for Plan B, which might be something like building a very narrow strip of pebble stone. I just worry about that dispersing over time.
What kind of contractor would be good at designing something like this? The gardeners seem to have fairly random ideas about it. Is there something equivalent to an "interior decorator" for outside garden areas? What should I be searching for in yellow pages?
