Erosion control measures on summits

Erosion control measures on summits

Erosion control measures on summits

(OP)
Hello,

I am coming up with an erosion control plan for a construction site on the summit of a mountain.  The soil is thin in some places (12" at most) and is mostly comprised of ledge/rock.  The area is an alpine zone, and there are concerns for the integrity of the flora of the area.  Because of this, hay bales are not to be used, and my thoughts now lean towards silt fencing.  Are there devices to drive silt fencing into rock?  Are they easy to use/effective/economic?  Are there any alternative sediment control products/techniques out there that I should be looking at instead?  Hope you can help.

Thanks,

Shane

RE: Erosion control measures on summits

you will probably have to drill into the rock to place the posts

try any of the following:

temporary diversion dikes - channels water to a desired location

temporary drainage swale - used in conjunction with a diversion dike to divert and carry water away from the excavation site

pipe slope drain - carries water down the slope without causing erosion

sediment basins - could use sand bags, rock check dam or a gravel filter berms to construct a basin to drop out the sediment
