DRAFT 12/2/14 exceed one hundred (100) cubic yards of earthwork provided work does not obstruct or modify a watercourse or storm sewer system and is not located in a floodplain; (B) installation and maintenance of fences, signs, posts, poles, electric, telephone, cable television, utility lines or individual service connections to these utilities; or (C) general farming practices, or (D) emergency work to protect life, limb, or property and emergency repairs, unless the land disturbing activity would have otherwise required an approved erosion and sediment control plan, except for the emergency. If such a plan would have been required, then the disturbed land area shall be shaped and stabilized in accordance with the city's requirements as soon as possible. Native vegetation is the pre-settlement (already existing in Minnesota at the time of statehood in 1858) group of plant species native to the local region, that were not introduced as a result of European settlement or subsequent human introduction. Normal water level refers to the permanent pool of water retained in a stormwater pond. By design, this is the water level below the invert elevation of the pond outlet with a depth not to exceed eight(8) feet. Ordinary high water level "Ordinary high water level" means the boundary of water basins, watercourses, public waters, and public waters wetlands, and: (A) the ordinary high water level is an elevation delineating the highest water level that has been maintained for a sufficient period of time to leave evidence upon the landscape, commonly the point where the natural vegetation changes from predominantly aquatic to predominantly terrestrial; (B) for watercourses, the ordinary high water level is the elevation of the top of the bank of the channel; and (C) for reservoirs and flowages, the ordinary high water level is the operating elevation of the normal summer pool. Outfall is the point of discharge to any watercourse from a public or private stormwater drainage system. Permanent cover means "final stabilization". Examples include grass, gravel, asphalt and concrete. See also the definition of"final stabilization". Pretreatment means directing stormwater runoff through a BMP or series of BMPs for the purpose of removing sediment and/or other pollutants prior to discharge into a receiving basin. Project is a planned undertaking resulting in changes to the condition of a property. Public Waters are waters of the state as defined in Minnesota Statutes, Section 103G.005, Subdivision 15. Retention facility is a temporary or permanent natural or manmade structure that provides for the storage of storm water runoff by means of a permanent pool of water. Runoff is rainfall, snowmelt, dewatering discharge, irrigation or any man-made sources of water flowing over the ground surface. Sediment is the product of an erosion process; solid material both mineral and organic, which is in suspension, is being transported, or has been moved by water, wind, or ice and has come to rest on the earth's surface either above or below water level. 27
