Indicators of anaerobic conditions include the accumulation of organic matter, low - chroma <br />soil matrices, mottling, and gleying. Other indicators may be found within the 1987 Manual. <br />The break between hydric and non -hyclric soils was determined by excavating random soil <br />pits within 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 property's boundaries. <br />132D- Havden fine sandy loam <br />Well drained hilly to steep soil found on short, narrow side slopes of glacial moraines. <br />Moderate permeability with rapid to very rapid surface runoff. High water capacity with low <br />organic content. <br />541 -Rifle muck <br />A. poorly drained level soil. Found in depressions on moraines, outwash plains and lake <br />plains. The surface layer is black muck about 9 inches thick. The middle layer is brown and <br />strong brown muckypeat about 12 inches thick. The lower layers are dark yellowish brown <br />and dark brown mucky 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 />860C&D -Urban land - Hayden- Kintrsleycomplex <br />I lly to steep complex found on knolls, hills and ridges. Permeability is 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, very poorly drained mineral and organic soils found around lakes or rivers and in <br />outwash plain depressions. <br />Hydrology <br />The criteria for wetland hydrology are satisfied when "the area is inundated either <br />permanently or periodically at mean water depths less than or equal to 6.6 ft., or the soil is <br />saturated to the surface at seine time during the growing season" (1987 Army Corps of <br />Engineers Wetland Delineation Manual). Saturation should occur within a "major part of <br />the root zone (usually within 12" of the 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 20" below the surface) is above biological zero (41° F). <br />2 <br />
