ORDINARY HIGH WATER LEVEL (OHWJ. The highest water level elevation that <br />has been maintained for a sufficiently long period of time to leave evidence upon the <br />landscape. The OHWL is commonly that point where the natural vegetation changes <br />from predominantly aquatic to predominantly terrestrial. If an OHWL has been <br />established for a waterbody by the Minnesota Department of Natural Resources, it will <br />constitute the OHWL under this definition. <br />OWNER. The person or party possessing the title of the land on which the <br />construction activities will occur; or if the construction activity is for a lease, easement, <br />or mineral rights license holder, the party or individual identified as the lease, easement, <br />or mineral rights license holder; or the contracting government agency responsible for <br />the construction activity. <br />POLLUTANT. A substance that pollutes something, especially water or the <br />atmosphere. <br />PUBLIC LINEAR PROJECT. A project involving a roadway, sidewalk, trail or utility <br />not part of an industrial, commercial, institutional or residential development. <br />RECONSTRUCTION. Removal of an impervious surface such that the underlying <br />structural aggregate base is effectively removed and the underlying native soil exposed. <br />REGIONAL FLOOD. A flood which is representative of large floods known to have <br />occurred generally in Minnesota and reasonably characteristic of what can be expected <br />to occur on an average frequency in the magnitude of the 1 % chance or 100-year <br />recurrence interval. REGIONAL FLOOD is synonymous with the term BASE <br />FLOOD used in the Flood Insurance Study. <br />SEASONAL HIGH WATER TABLE. The highest known seasonal elevation of <br />groundwater as indicated by redoximorphic features such as mottling within the soil. <br />SATURATED (RATED SOIL.The highest seasonal elevation in the coil that is in a re`dUGed <br />c�-rry�c�-ry rr-rrcr��.lvTr��rrcrTccrcrcccr <br />chemical state beGause of son! voids beiRg foiled with water.

SEDIMENT CONTROL practices include silt fences, sediment traps, earth dikes, <br />drainage swales, check dams, subsurface drains, pipe slope drains, storm drain inlet <br />protection, and temporary or permanent sedimentation basins. <br />SHORELAND. Land located within the following distances from the ordinary high <br />water elevation of public waters: <br />(a) Land within 1,000 feet from the normal high watermark of a lake, pond or <br />flowage; and <br />(b) Land within 300 feet of a river or stream or the landward size of a floodplain <br />delineated by ordinance on the river or stream, whichever is greater. <br />STABILIZED. The exposed ground surface has been covered by appropriate <br />materials such as mulch, staked sod, riprap, erosion control blanket, mats or other <br />material that prevents erosion from occurring. Applying mulch, hydromulch, tackifier, <br />
