(aa) REDEVELOPMENT: The demolition or removal of existing structures or land uses and construction of new ones.
(bb) RETENTION BASIN: A storm water management pond that maintains a permanent pool of water. These storm water management ponds include a properly engineered/designed volume dedicated to the temporary storage and slow release of runoff waters.
(cc) RIPARIAN AREA: Naturally vegetated land adjacent to watercourses which, if appropriately sized, helps to limit erosion, reduce flood flows, and/or filter and settle out runoff pollutants, or which performs other functions consistent with the purposes of these regulations.
(dd) RIPARIAN SETBACK: Those lands within the Community which are alongside streams, and which fall within the area that the Community prohibits and restricts changes in land use and the building of structures.
(ee) SEDIMENT: Solid material, both mineral and organic, that is in suspension, is being transported, or has been moved from its site of origin by wind, water, gravity or ice, and has come to rest on the earth's surface either on dry land or in a body of water.
(ff) SEDIMENT BASIN: A temporary Sediment Pond that releases runoff at a controlled rate. It is designed to slowly release runoff, detaining it long enough to allow most of the sediment to settle out of the water. The outlet structure is usually a designed pipe riser and barrel. The entire structure is removed after construction. Permanent storm water detention structures can be modified to function as temporary Sediment Basins.
(gg) SEDIMENT CONTROL: The limiting of sediment being transported by controlling erosion or detaining sediment-laden water, allowing the sediment to settle out.
(hh) SEDIMENT POLLUTION: A failure to use management or conservation practices to control wind or water erosion of the soil and to minimize the degradation of water resources by soil sediment in conjunction with land grading, excavating, filling, or other soil-disturbing activities on land used or being developed for commercial, industrial, residential, or other purposes.
(ii) SEDIMENT TRAP: A temporary sediment-settling pond having a simple spillway outlet structure stabilized with geotextile and rip rap.
(jj) SENSITIVE AREA: An area or water resource that requires special management because of its susceptibility to sediment pollution, or because of its importance to the well-being of the surrounding communities, region, or the State and includes, but is not limited to, the following:
(1) Ponds, wetlands or small lakes with less than five acres of surface area;
(2) Small streams with gradients less than ten feet per mile with average annual flows of less than 3.5 feet per second containing sand or gravel bottoms.
