Sediment Control - The methods employed to prevent sediment from leaving the
<br />development site. Sediment control practices include silt fences, sediment traps, earth dikes,
<br />drainage swales, check dams, subsurface drains, pipe slope drains, storm drain inlet protection,
<br />and temporary or permanent sedimentation basins.
<br />
<br /> Soil - The unconsolidated mineral and organic material on the immediate surface of the
<br />earth. For the purposes of this document stockpiles of sand, gravel, aggregate, concrete or
<br />bituminous materials are not considered "soil" stockpiles.
<br />
<br /> Stabilized - The exposed ground surface after it has been covered by sod, erosion control
<br />blanket, riprap, or other material that prevents erosion from occurring. Simply sowing grass seed
<br />is not considered stabilization.
<br />
<br /> Storm Water - Under Minnesota Rule 7077.0105, subpart 41 b storm water, "means
<br />precipitation runoff, storm water runoff, snow melt runoff, and any other surface runoffand
<br />drainage." (According to the Federal Code of Regulations under 40 CFR 122.26 [b] [13], "Storm
<br />water means storm water runoff, snow melt runoff and surface and drainage."). Storm water does
<br />not include construction site &watering.
<br />
<br /> Storm Water Pollution Control Plan - A joint storm water and erosion and sediment
<br />control plan that is a document containing the requirements of Section 4, that when implemented
<br />will decrease soil erosion on a parcel of land and off-site nonpoint pollution.
<br />
<br /> Structure - Anything manufactured, constructed or erected which is normally attached to
<br />or positioned on land, including portable structures, earthen structures, roads, parking lots, and
<br />paved storage areas.
<br />
<br /> Subdivision - Any tract of land divided into building lots for private, public, commercial,
<br />industrial, etc. development. Minnesota Rule 6120.2500, subpart 17 defines subdivision as, "...
<br />land that is divided for the purpose of sale, rent, or lease, including planned unit development."
<br />
<br /> Temporary Protection - Short term methods employed to prevent erosion. Examples of
<br />such protection include; mulch, erosion control blankets, wood chips, and erosion netting.
<br />
<br />Urban - Of, relating to, characteristic of, constituting a city.
<br />
<br /> Vegetated or Grassed Swales - A vegetated earthen channel that conveys storm water,
<br />while treating the storm water by biofiltration. Such swales remove pollutants by both filtration
<br />and infiltration.
<br />
<br /> Waters of the State - As defined in Minnesota Statutes section 115.01, subdivision 22
<br />the term "... "waters of the state" means all streams, lakes, ponds, marshes, watercourses,
<br />waterways, wells, springs, reservoirs, aquifers, irrigation systems, drainage systems and all other
