WETLAND DELINEATION REPORT <br /> Silver View Pond Restoration <br /> Results <br /> October 26, 2023 <br /> Soils within the wetland are mapped by the NRCS as Seelyeville muck and Zimmerman fine sand(Appendix <br /> A, Figure 2). The soils observed at the sample points were generally consistent with the Seelyeville series <br /> characteristics. Field indicators of hydric soil identified at sample point W04-1w consisted of NRCS field <br /> Indicators Al-Histosol. Therefore, the hydric soil criterion was satisfied. <br /> The wetland boundary was determined based on distinct differences in vegetation, hydrology, soils, and <br /> topography consisting of the following: 1)Transition from a shallow open water wetland community <br /> dominated by reed canary grass and black willow to a mesic forest upland community dominated by <br /> ground ivy, hackberry(Celtis occidentalis, FAC), and common buckthorn; 2)Transition from an area <br /> exhibiting wetland hydrology indicators within the wetland to a lack of wetland hydrology indicators within <br /> the adjacent upland; and 3)Transition from soils exhibiting hydric soil indicators to soils lacking indicators <br /> of hydric soil conditions. The transition from wetland to upland characteristics generally correlated with a <br /> well-defined topographic break. <br /> 3.3.5 Wetland 5 <br /> Wetland 5(W05) is a shallow open water community that is a part of a wetland complex which is central to <br /> all five sections of the Project. W05 is connected to a culvert along its southeast boundary. Most of the <br /> wetland is made up of the shallow open water community but the sample point was taken in a thin wetland <br /> fringe along the open water(Appendix A, Figure 1). <br /> Dominant plant species identified at sample points completed within W05 consist of black willow and <br /> willowherb (Epilobium coloratum, OBL). Other common species identified in the wetland are listed on the <br /> data forms included in Appendix C. The dominant species within the wetland are comprised mostly of <br /> hydrophytic vegetation (OBL, FACW, and/or FAC)and meet the hydrophytic vegetation criterion. <br /> The wetland appears to have a seasonally inundated/saturated hydroperiod within the center. Primary <br /> Hydrology Indicators observed were A2, A3, and Hydrogen Sulfide Odor (C1). Secondary indicators of <br /> wetland hydrology observed included D2 and D5. Therefore, the wetland hydrology criterion was met. <br /> Soils within the wetland are mapped by the NRCS as Udorthents,wet substratum and Urban land(Appendix <br /> A, Figure 2). The soils observed at the sample points were generally consistent with the Seelyeville and <br /> Markey series characteristics found along other parts of the wetland complex. Field indicators of hydric soil <br /> identified at sample point W05-1w consisted of NRCS field Indicators A3-Black Histic and S4-Sandy Gleyed <br /> Matrix. Therefore, the hydric soil criterion was satisfied. <br /> The wetland boundary was determined based on distinct differences in vegetation, hydrology, soils, and <br /> topography consisting of the following: 1)Transition from a shallow open water wetland community <br /> dominated by willowherb and black willow to a maintained lawn upland community dominated by <br /> Kentucky blue grass and black mustard (Brassica nigra); 2)Transition from an area exhibiting wetland <br /> hydrology indicators within the wetland to a lack of wetland hydrology indicators within the adjacent <br /> upland; and 3)Transition from soils exhibiting hydric soil indicators to soils lacking indicators of hydric soil <br /> conditions. The transition from wetland to upland characteristics generally correlated with a well-defined <br /> topographic break. <br /> 3.3.6 Wetland 6 <br /> Wetland 6(W06) is a shallow open water community that is a part of a wetland complex which is central to <br /> all five sections of the Project. Most of the wetland is made up of the shallow open water community but <br /> the sample point was taken in a thin wetland fringe along the open water(Appendix A, Figure 1). <br /> Dominant plant species identified at sample points completed within W01 consist of American elm and <br /> Bebb's willow (Salix bebbiana, FACW). Other common species identified in the wetland are listed on the <br /> 7 <br />
