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 (Cl). 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 />
