.~ <br />,° <br />;~ ~~ <br />j, <br />~~ <br />Tnc{icators of anaerobic conditions include the accumulation of organic matter, low-diroma <br />soil matrices, mottling, and gleying. Other indicators maybe found within the 1937 iVlamtal. <br />'Ihc break between hydric and non-hvdr-ic soils was detem7ined by excavating random soil <br />pits w-ithii multiple wetland/upland areas and examining the soils for the presence of <br />anaerobic indicators. <br />According to the Washington County Soil Survey the following soils types are present within <br />the propem's boundaries. <br />132D-E-1<2vden fine sane{v loam <br />Well drained hilly to steep soil found on shoe, narrow side slopes of glacial moraites. <br />Moderate permeability with rapid to very rapid surface nmoff. High water capacitywith low <br />onanic content. <br />541-Rifle muck <br />A poorly drained level soil. Fotmd in depressions on moraines, outwash plains and lake <br />plains. The surface layer is black muck about 9 inches thick 'Ihe middle layer is brown and <br />strong brown mucky peat about 12 inches thick The lower layers are dark yellowish brown <br />and dark brown muclry peat. It has moderately rapid permeability and very high available <br />water capacity and organic content. The seasonal high water table is at a depth of less than <br />one foot. <br />360C~D-Urban land-Havclen-Kingslevcomples <br />Hilly to steep complex found on knolls, hills and ridges. Permeabiliryis moderate to <br />moderately slow with moderate to high available water capacity. Runoff from this complex <br />is rapid. <br />1055-Aquolls and histosols, ponded <br />Level, verypoorlydrained mineral and organic soils found around lakes or rivers and in <br />outwash plain depressions. <br />Hydrology <br />The criteria fox wetland hydrology are satisfied ~chen "the area is inundated either <br />permanently or periodicallyat mean water depths less than or equal to 6.6 ft., or the soil is <br />saturated to die surface at some time during die growing season" (1987 .~crny Corps of <br />Engineers Weiland Delineation Manual). Saturation should occur within a "major part of <br />the root zone (usually ~vidun 1?" of die surface)". Typically, the area must be inundated for <br />at least 5% of the growing season. The growing season is defined as the portion of the year <br />when soil temperature (measured ?0" below the surface) is above biological zero (41° P). <br />
