EXHIBIT A: EXISTING CHAPTER 927 Storm Water Management and Urban 66C Sediment Pollution Abatement Systems 927.03 (oo) "Sloushin " means a slip of downward movement of an extended layer of soil resulting from the undermining action of water or the earth disturbing activity of man. (pp) "Soil" means unconsolidated erodible earth material consisting of minerals and/or organics. (qq) "Soil Loss" means soil moved from a site by the forces of erosion and redeposited at another site on land or in a body of water. (rr) "Soil Stabilization" means vegetative or structural soil cover controlling erosion and includes permanent and temporary seed, mulch, sod, pavement, etc. (ss) "Storage" means the control, retention, or detention of runoff. (1) 'Detention Storage" means storm runoff collected and stored for a short period of time and then released at a controlled rate. (Dry Pond) (2) "Retention Storage" means storm runoff collected and stored for a short period of time and which is released at a controlled rate leaving in the facility a permanent pool of water. This facility is often associated with water -related recreational or aesthetic uses. (Wet Pond) �3) "Underground Storage" means storm runoff collected and stored or a short period of time and then released at a controlled rate from a system of underground pipes or vaults. (tt) "Storage Facility" means any facility used to store, retain or detain storm runoff, which shall include but not be limited to retention and detention storage facilities, underground pipe, rooftop or parking lot storage, basins, depressions and pools. (uu) "Storm Frequency" means the average period of time in which a storm of a given duration and intensity can be expected to be equaled or exceeded. (vv) "Storm Drainage System" means the surface and subsurface system for the removal of water from the land, including both the natural elements of streams, gullies, ravines, marshes, swales and ponds, whether of an intermittent or continuous nature, and man-made elements which include conduits and appurtenant features, culverts, ditches, channels, storage facilities, streets, and the storm sewer system. (1) "Initial Drainage System" means that part of the storm drainage system which is used regularly for collecting, transporting, and disj)osing of storm runoff, snow melt, and miscellaneous minor flows. The initial system is also termed the "convenience system", "minor system", or the "storm sewer system", and may include many features ranging from curbs and gutters to storm sewer pipes and open drainage ways. (2) "Major Drainage System" means that storm drainage system which carries the runoff from a storm having a frequency of occurrence of once in 100 years. The major system will function whether or not it has been planned and designed and whether or not improvements are situated wisely in respect to it. The major system is also termed the "Emergency Flow Way." The major system usually includes many features such as streets, ravines, and major drainage channels. Storm sewer systems may reduce the flow in many parts of the major system by storing and transporting water underground.
