Wetland A, as defined previously, is located west of the maintained lawn behind the existing house (Figure 5). The boundary of this wetland was delineated based on site topography and site conditions. Wetland A was not identified on the NWI map (Figure 2). However, Schoell Madson classified the wetland as a Type 3 Inland shallow fresh marsh. Wetland A was dominated by an unknown species of cattail (Typha sp.), and reed canary grass (Phalaris arundinacea) in the herbaceous layer. The shrub layer was comprised of red-osier dogwood (Cornus stolonifera). The upper canopy was comprised of Eastern cottonwood (Populus deltoides). The data was collected at representative sample locations within the wetland and upland areas. The wetland area was' located in a low topographic position with obvious drainage patterns. Hydrology was observed at the surface of the wetland area and the soil was saturated at the surface. The soil profile within the wetland at the first transect consisted of 0-6 inches of very dark brown (10YR 2/2) silty clay loam in the upper layer. The lower portion of the soil profile consisted of 6-24 inches of dark gray (10YR 4/1) with dark reddish brown (5YR 3/4) mottles at approximately 40 percent coverage along with light olive brown (2.5 Y 5/4) at approximately 30 percent coverage. These soils do not concur with the local soil survey, which are classified as well drained Angus loam (USDA, 2004). Angus loam soils are not listed on the federal and county hydric soils lists. The soil profile at the second transect consisted of 0-12 inches of very dark gray (10 YR 3/1) silt loam. The lower portion of the soil profile consisted of dark gray (10 YR 4/1) clay loam with dark reddish brown (5 YR 3/4) mottles at approximately 25 percent coverage along with black (10YR 2/1) mottles at approximately 5 percent coverage. The soils do not concur with the local soil survey, which are classified as poorly to very poorly drained Tadkee soils (USDA, 2004). Tadkee soils are listed on the federal and county hydric soils lists. The upland vegetation was dominated by Kentucky blue grass (Poa pratensis), and goldenrod sp. (Solidago sp.) in the herbaceous layer. The shrub layer was dominated by common buckthorn (Rhamnus cathartica). The upper canopy was dominated by mixed deciduous trees. Soil samples were taken from the adjacent upland areas at representative sampling stations. As a result, the soil profile at the first transect consisted of 0-18 inches of very dark brown (10YR 2/2) sandy loam. The second soil transect was consistent with the initial findings. These soils concur with the local soil survey, which are classified as well drained Angus loam (USDA, 2004). Hydrology was not found in the upper 18 inches of the soil profile.
