tively small home in a good location has more than 300 cubic yards of dirt just waiting to flow away with the next rainfall.
To protect the neighboring properties and the roadway, the driveway should have a silt fence 1200 feet long' on both sides to keep the loose dirt from transferring during a rain event. The dirt pile should be surrounded by a silt fence (100 feet long'. Any area on the downhill side of the excavation, where water would naturally drain, would also require a silt fence i100 feet long'.
The driveway should have stone that is large enough (three to four inches in diameter' to capture any dirt or mud on equipment tires before vehicles leave the construction site (about 20 tons of stone'. Add 20 straw bales for additional protection in areas where a silt fence is not easily erected. The cost is $1,000 for the silt fence (at $2.50 per foot installed) and $90 for the straw bales ($4.50 each), for a grand total of $1,090.
Prevention
vs. repair
Now let’s compare the cost of prevention with the cost of repair. From the same company, the cost to transport and operate a backhoe with a four-hour minimum is $125 per hour plus an $80 per hour operator’s fee. Transporting any dirt or debris is $55 per hour plus one hour of travel time. Raking the damaged area, including the damage from the cleanup equipment, will cost $60 per hour, plus some labor to spread seed and straw at $51 per hour, plus materials (an estimated $100). Total cost for eight hours of cleanup is then $3,078.
Repair in this case costs $1,988, almost 200 percent,
83.6%
