SCM Repair Services may include work on various NCDOT SCMs such as dry/wet detention basins, bioretention areas, bio-filtration conveyances, level spreaders, grass swales, bioswales, infiltration swales/basins, stormwater wetlands, permeable pavement, and hazardous spill basins. SCM Repair Services may include both routine and non-routine maintenance and repairs of SCMs. Work may include, but is not limited to, dewatering SCMs prior to performing repairs; removal of undesirable vegetation/woody debris from SCMs; unclogging SCM pipes by cleaning out debris/overgrowth; replanting basins; removal of accumulated sediment and/or sediment laden riprap, litter, or other debris from forebays/basins; repairing washouts; and restabilizing areas after maintenance and repairs are completed.
