EXHIBIT A: EXISTING CHAPTER 927 Storm Water Management and Urban 66A Sediment Pollution Abatement Systems 927.03 (1) "Drainage Way" means a channel or storm sewer used to drain an area. (m) "Dumping" means grading, pushing, piling, throwing, unloading or placing of soil. (n) "Earth Disturbing Activity" means any grading, excavating, filling, or other alteration of the earth's surface where natural or man-made ground cover is destroyed and which may result in or contribute to erosion and sediment pollution. (o) "Earth Material" means soil, sediment, rock, sand, gravel, and organic material or residue associated with or attached to the soil. (p) "Emergency Flow Way" means the drainage way necessary to convey a 100 year storm. (q) "Engineer" means the City Engineer or his designated representative. (r) "Erosion" means the process by which the land surface is worn away by the action of water, wind, ice or gravity. (s) "Erosion and Sediment Control Plan" means a written and/or drawn sediment pollution abatement plan or strategy to minimize erosion and prevent off-site sedimentation throughout all earth disturbing activities on a development area. (t) "Erosion and Sediment Control Practices" means conservation measures used to abate sediment pollution and includes structural practices, vegetative practices and management techniques. (u) "Flood" means the temporary inundation of any land not normally covered by water due to heavy rainfall or runoff or due to a temporary rise in the level of rivers, streams, watercourses, or lakes. (1) "Average Annual Flood" means a flood equal to the mean of discharges of all the maximum annual floods during the period of record. (2) "Regional Flood" means the name applied to the 100 -year flood in flood plain information reports. The 1 -year flood has a one percent probability of being equalled or exceeded in a period of 100 years. (3) "Maximum Probable Flood" means the largest flood discharge believed possible considering the meteorologic conditions and snow cover on the watershed. (v) "Floodway" means the channel of the watercourse and those portions of the adjoining flood plain which are used to convey the regional flood. (w) "Frequency Storm" means a rainfall event of a magnitude with a specified average recurrence interval and is calculated with soil conservation service Type II twenty-four hour curves or depth -duration frequency curves. (x) "Grading" means earth disturbing activity such as excavation, stripping, cutting, filling, stockpiling, or any combination thereof. (y) "Grubbing" means removing, clearing or scalping material such as roots, stumps or sod. (z) "Highly Erodible Soil" means a portion of land surface which is very susceptible to erosive forces and is characterized by a high soil erodibility factor, steep slopes or long slopes.
