Aiken County already has some ordinances on the books about new construction, but now there's new state regulations through the South Carolina Department of Health and Environmental Control. In the past, anything less than five acres of disturbance was not required to have an erosion control permit. Now, they've lowered that threshold down to anything one acre or above of commercial development and anything two acres or above of residential development of a disturbed area is going to be required to have a stormwater development plan.  This plan will include proper uses of perimeter sediment control products (straw wattles, silt fence) and temporary erosion control products (erosion control blankets, hydraulic mulch).  With post construction, the ordinance is intended to address the maintenance of a construction site after completion of a project so as to protect the water quality.
