Customer just asked me extend thier parking lot another 10 feet. How much stone in tons would I need? (landscaping we figure 1 ton per 100 SF) 2" deep. 200' would be crushed limestone. 200' along another side would be matching up with drainage area and using 2.5" stone. I thought 50 ton. Also could the laying of the stone be done in 15 hours or less with a bobcat? The stone woud be dumped at 1 end of the lot So the last of it will be moved about 200'. Thanks this is the first time for this.
