I notice all along road construction projects the contractors install about a foot tall plastic sheeting that appears to hinder errosion of freshly worked ground. It is usually near ditches and culverts.
Is this a state/federal law requiring it? Or part of the contract to build the road, or does it save some effort, like having to clean out culverts that fill with erroded soil?
Just curious. THANKS.
