TRACT All contiguous land and bodies of water being disturbed or to be disturbed as a unit, regardless of ownership. TWENTY-FIVE YEAR STORM The storm water runoff resulting from precipitation of an intensity expected to be equaled or exceeded on the average, once in 25 years, and of a duration which will produce the maximum peak rate of runoff for the watershed of interest under average antecedent wetness conditions. UNBUILDABLE AREAS Areas that have highly erodible soils or slopes in excess of 60%. UNCOVERED The removal of ground cover from, on, or above the soil surface. UNDERSTORY TREE Small-growing trees with an expected mature height of 20 to 40 feet. UPPER WATERSHED DRAINAGEWAY A natural or artificial stream or depression that drains more than 5 acres of surface water located within a Water Supply Watershed Overlay District. VESTED RIGHT The right to undertake and complete the development and use of property under the terms and conditions of an approval secured as specified by NC General Statutes or under common law. VELOCITY The average velocity of flow through the cross section of the main channel at the peak flow of the storm of interest. The cross section of the main channel is defined by the geometry of the channel plus the area of flow below the flood height defined by vertical lines at the main channel banks. Overload flows are not to be included for the purpose of computing velocity of flow. VIOLATION (FLOODPLAIN DEVELOPMENT) The failure of a structure or other development to be fully compliant with the community’s floodplain management regulations. A structure or other development without the elevation certificate, other certifications, or other evidence of compliance is presumed to be in violation until such time as that documentation is provided. WALL SIGN Flat signs or lettering which are painted or attached to the wall of a building or structure.
WASTE Surplus soil or earth materials resulting from on-site construction and disposed of at other locations. WATER SURFACE ELEVATION (WSE) (FLOODPLAIN DEVELOPMENT) The height, in relation to mean sea level, of floods of various magnitudes and frequencies in the floodplains of coastal or riverine areas. WATERCOURSE (FLOODPLAIN DEVELOPMENT) A lake, river, creek, stream, or other topographic feature on or over which waters flow at least periodically. Watercourse includes specifically designated areas in which substantial flood damage may occur. WATERCOURSE BUFFER ZONE The strip of land adjacent to a lake, river, creek, stream. WETLANDS Wetlands are areas that are inundated or saturated by surface or ground water at a frequency and duration sufficient to support, and that under normal circumstances do support, a prevalence of vegetation typically adapted for life in saturated soil conditions. Wetlands generally include swamps, marshes, bogs, and similar areas. This definition of wetlands is used by the U.S. Army Corps of Engineers (Corps) and the U.S. Environmental Protection Agency (EPA) since the 1970s for regulatory purposes in Section 404 of the Clean Water Act. WINDOW SIGN Flat signs or lettering which are painted or attached to the window of a building or structure. These signs also include retail window displays which are intended to showcase/advertise goods and products to pedestrians on the sidewalk. WORKING DAYS Days exclusive of Saturday, Sunday, Federal and State holidays during which weather conditions or soil conditions permit land-disturbing activity to be undertaken under the Land Disturbance Permit.
