DRAFT 12/2/14 preventing and reducing the degradation of surface water as published by state or designated area-wide planning agencies. Buffer means land that is used to protect adjacent lands and waters from\development and more intensive land uses. The land is kept in a natural state of trees, shrubs, and low ground cover and understory of plants and functions to filter runoff, control sediment and nutrient movement, and protect fish and wildlife habitat. In areas of agricultural use, the land may be used for less intensive agricultural purposes provided its function as a buffer remains intact. Channel means a natural or artificial watercourse with a definite bed and banks that conducts continuously or periodically flowing water. Common Plan of Development or Sale is a contiguous area where multiple separate and distinct land disturbing activities may be taking place at different times, or on different schedules, but under one proposed plan. This item is broadly defined to include design, permit application, advertisement or physical demarcation indicating that land-disturbing activities may occur. Detention facility is a temporary or permanent natural or man-made structure that provides for the temporary storage of stormwater runoff. Discharge is the release, conveyance, channeling, runoff or drainage of stormwater, including snowmelt, from a construction or development site. Filter strip is a vegetated section of land designed to treat runoff as overland sheet flow. It may be designed in any natural vegetated form from a grassy meadow to a small forest. The dense vegetated cover facilitates pollutant removal,reduces erosion and promotes infiltration. Floodplain the channel or beds proper and the areas adjoining a wetland, lake or watercourse that have been or hereafter may be covered by the regional flood. High water level is the expected elevation the water in a stormwater pond will rise to a 100 year rain event as calculated by the pond design. Hydric soils are soils that are saturated, flooded, or ponded long enough during the growing season to develop anaerobic conditions in the upper soil horizon. Hydrologic Soil Group (HSG) means a Natural Resource Conservation Service classification system in which soils are categorized into four runoff potential groups. The groups range from A soils, with high permeability and little runoff production, to D soils, which have low permeability rates and produce much more runoff. Impaired Waters are water bodies that do not meet water quality standards and designated uses because of pollutant(s),pollution, or unknown causes of impairment. Impervious surface is a constructed hard surface that either prevents or retards the entry of water into the soil and causes water to run off the surface in greater quantities and at an increased rate of flow than existed prior to development. Examples include rooftops, sidewalks, patios, driveways, parking lots, storage areas, and concrete, asphalt, or gravel roads. Class 5 gravel surfaces are considered to be impervious surfaces. Land disturbance activity is any land change that may result in soil erosion from water or wind and the movement of sediments into or upon waters or lands within this government's jurisdiction, including but not limited to construction, clearing and grubbing, grading, excavating, transporting and filling of land. Within the context of this ordinance, land disturbance activity does not mean: (A) minor land disturbance activities including, but not limited to,underground utility repairs, home gardens, home landscaping, minor repairs and maintenance work which do not disturb more than two thousand (2,000) square feet of land or 26
