"Filter cloth" means a geotextile fabric designed to allow water to pass through the membrane while retaining sediments. For purposes of this chapter, filter cloth is typically utilized under sills and marsh toe revetments to minimize settling and along the landward side of marsh toe revetments to minimize sediment loss from the adjacent marsh substrate.

"Shell bags" means net bags of various sizes filled with oyster or clam shells used for erosion control and as a substrate for other organisms.

"Tidal wetlands" or "wetlands" means the jurisdictional area meeting the definition contained in § 28.2-1300 of the Code of Virginia.
