The following words and terms when used in this chapter shall
				  have the following meanings, unless the context clearly indicates
				  otherwise:
"Chairman" means the chairman of a local wetlands board or
				  his designee.
"Commission" or "VMRC" means the Virginia Marine Resources
				  Commission.
"Commissioner" means the Commissioner of Marine Resources or
				  his designee.
"Dune and beach vegetation" means the vegetative species
				  listed in §
									28.2-1400 of the Code
				  of Virginia.
"Fetch" means the distance along open water over which wind
				  blows.
"Fiber log" means biodegradable fibrous material often
				  composed of coconut fiber that is formed into rolls of various lengths and
				  thicknesses used for erosion control and as a growing medium.
"Fiber mat" means a biodegradable fibrous material often
				  composed of coconut fiber that is formed into mats of various sizes and
				  thicknesses used for erosion control and as a growing medium.
"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.
"Grazing protection" means temporary structures consisting of
				  wooden stakes, string lines, netting, and metal cages intended to protect
				  planted wetland vegetation and introduced ribbed mussels from predation.
"Joint Permit Application" means the current Joint Permit
				  Application utilized by the U.S. Army Corps of Engineers, Virginia Marine

				  wetlands boards to evaluate projects involving submerged lands, wetlands, and

				  application developed specifically for this general permit.
"Living shoreline" means a shoreline management practice that
				  provides erosion control and water quality benefits; protects, restores, or
				  enhances shoreline habitat; and maintains coastal processes through the
				  strategic placement of plants, stone, sand fill, and other structural and
				  organic materials.
"Marsh toe revetment" means an erosion control structure
				  constructed of riprap or shell bags placed immediately channelward of an
				  eroding marsh. A marsh toe revetment is generally utilized to halt the erosion
				  of an existing vegetated marsh that is currently wide enough to provide erosion

"Riprap" means heavy rock utilized to construct sills and
				  revetments.
"Sand dunes and beaches" means the jurisdictional areas
				  meeting the definitions of coastal primary sand dunes and beaches contained in

				  of Virginia.
"Sill" means a linear erosion control structure constructed
				  of riprap, shell bags, or other approved material placed channelward of and
				  generally parallel to an eroding shoreline. Sand is often placed landward of
				  the sill to raise the elevation of the substrate and facilitate the
				  establishment of wetlands vegetation.
"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.
"Unaltered shoreline" means a shoreline segment that does not
				  already have an erosion control structure in place.
"Wetlands board" or "board" means a local wetlands board
				  created pursuant to §
									28.2-1303
				  of the Code of Virginia.
"Wetlands vegetation" means the vegetative species listed in
				  §
									28.2-1300 of the Code
				  of Virginia.
"Woven containment bag" means a biodegradable bag generally
				  filled with a mixture of sand, gravel, mulch, and soil and planted with
				  wetlands or beach and dune vegetation.
