Subd. 10. FINAL STABILIZATION: All soil disturbance activities on the site or common plan of development or sale have been completed, and that a uniform (evenly distributed, e.g., without large bare areas)perennial vegetative cover with a density of at least seventy percent (70%) of the cover for unpaved areas and areas not covered by permanent structures has been established, or equivalent permanent stabilization measures have been employed, and that all temporary erosion control devises are removed, including silt fence, temporary sedimentation basins, and temporary standpipes. Simply sowing grass seed and/or mulch is not considered final stabilization. Final stabilization of a common plan of development or sale includes completion of building or home construction along with final restoration of all yards and adjacent drainage ways and shall be in conformance with the NPDES Construction General Permit Part IV.G. Subd. 11. GRADE: The vertical location of the ground surface. Subd. 12. GRADING: Any excavating or filling or combination thereof. Subd. 13. LAND DISTURBANCE ACTIVITY: Any land change that may result in soil erosion from water or wind and the movement of sediment into or upon waters or lands within the City's jurisdiction, including construction, clearing and grubbing, grading, excavating,transporting and filling of land. Subd. 14. LAND DISTURBANCE PLAN: A joint storm-water and erosion and sediment control plan that is a document containing the requirements of this Chapter and the City of Mounds View Land Disturbance Plan and Implementation Requirements, that when implemented will decrease soil erosion on a parcel of land and off-site nonpoint pollution. It involves both temporary and permanent controls. Subd. 15. NPDES: The National Pollutant Discharge Elimination System is a provision of the Clean Water Act that prohibits discharge of pollutants into waters of the U.S. unless a special permit is issued by the EPA, a state, or a tribal government. Subd. 165. PERMANENT CONTROLS: Erosion and/or sediment control measures installed that are not intended to be removed from the project site. Examples of such protection are swales,ponds, sediment basins,turf reinforcement mats, storm sewer systems, and riprap. Subd. 176. PERMANENT COVER: Examples including grass, gravel, asphalt, and concrete. See also the definition of final stabilization. Subd. 187. PERMIT: A written warrant or license granted for land disturbance activities. Subd. 19g. SEDIMENT: The product of an erosion process; solid material both mineral and organic, that is in suspension, is being transported, or has been moved by water, wind, or ice, and has come to rest either above or below water level. Subd. 204-9. SEDIMENTATION: The process or action of depositing sediment. Subd. 218. SEDIMENT CONTROL: The methods employed to prevent sediment from leaving a site. Examples of sediment control practices are silt fences, sediment traps, earth dikes, drainage swales, check dams, subsurface drains, storm drain inlet protection, and temporary or permanent sedimentation basins.
