Water surface elevation means the height, in relation to the National Geodetic Vertical Datum (NGVD) of 1929, the North American Vertical Datum (NAVD) of 1988, or other datum, where specified, of floods of various magnitudes and frequencies in the floodplains of riverine areas.
water meter means any apparatus for measuring or showing the volume of water supplied to, or of effluent discharged from any premises;
Drainage system means one or more artificial ditches, tile drains or similar devices which collect surface runoff or groundwater and convey it to a point of discharge.
Surface waters means all waters of the state as defined in G.S. 143-212 except underground waters
Erosion means the detachment and movement of soil or rock fragments by water, wind, ice, or gravity.
Groundwater means all water, which is below the surface of the ground in the saturation zone and in direct contact with the ground or subsoil.
Drainage area means a geographic area within which stormwater, sediments, or dissolved materials drain to a particular receiving waterbody or to a particular point along a receiving waterbody.
Floodplain or flood-prone area means any land area susceptible to being inundated by water from any source (see definition of “flood”).
Drainage means the movement of water to a place of disposal, whether by way of the natural characteristics of the ground surface or by artificial means;

Sediment means solid material, mineral or organic, that is in suspension, is being transported, or has been moved from its site of origin by air, water or gravity as a product of erosion.
Potable means water suitable for drinking by the public.
Water Surface Elevation (WSE means the height, in relation to NAVD 1988, of floods of various magnitudes and frequencies in the floodplains of riverine areas.
