3.029 Paved Surface A constructed hard, smooth surface made of asphalt, concrete or other pavement material. Examples include, but are not limited to, roads, sidewalks, driveways and parking lots. 3.030 Permanent Cover Means "final stabilization." Examples include grass, gravel, asphalt, and concrete. See also the definition of "final stabilization." 3.031 Runoff Coefficient The fraction of total precipitation that is not infiltrated into or otherwise retained by the soil, concrete, asphalt or other surface upon which it falls, that will appear at the conveyance as runoff. This coefficient is usually estimated for an event or on an average annual basis. 3.032 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 on the earth's surface either above or below water level. 3.033 Sedimentation The process or action of depositing sediment. 3.034 Sediment Control The methods employed to prevent sediment from leaving the development site. Sediment control practices include silt fences, sediment traps, earth dikes, drainage swales, check dams, subsurface drains, pipe slope drains, storm drain inlet protection, and temporary or permanent sedimentation basins. 3.035 Soil The unconsolidated mineral and organic material on the immediate surface of the earth. For the purposes of this document stockpiles of gravel, aggregate, concrete or bituminous materials are not considered "soil" stockpiles. 3.036 Stabilized The exposed ground surface after it has been covered by sod, erosion control blanket, riprap, or other material that prevents erosion. Simply sowing grass seed is not considered stabilization. 3.037 Storm Water Under Minnesota Rule 7077.0105, subpart 41b storm water, "means precipitation runoff, storm water runoff, snow melt runoff, and any other surface runoff and drainage." (According to the Federal Code of Regulations under 40 CFR 122.26 [b][13], "Storm water means storm water runoff, snow melt runoff and surface and drainage. "). Storm water does not include construction site dewatering. 3.038 Storm Water Pollution Control Plan A joint storm water and erosion and sediment control plan that is a document containing the requirements of Section 4, that when implemented will decrease soil erosion on a parcel of land and off -site nonpoint pollution. It involves both temporary and permanent controls. 3.039 Structure Anything manufactured, constructed or erected which is normally attached to or positioned on land, including portable structures, earthen structures, roads, parking lots, and paved storage areas.
