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
Resources Commission, Virginia Department of Environmental Quality, and local
wetlands boards to evaluate projects involving submerged lands, wetlands, and
coastal primary sand dunes and beaches for permit review and any abbreviated
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
control benefits.
"Ribbed mussels" means the Atlantic ribbed mussel (Geukensia
demissa).
"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
§
28.2-1400 of the Code
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.
