WETLAND DELINEATION REPORT <br />Silver View Pond Restoration <br />Results <br />October 26, 2023 <br />3.3.8 Wetland 8 <br />Wetland 8 (W08) is made up of a hardwood swamp and shallow open water communities that is a part of <br />a wetland complex which is central to all five sections of the Project (Appendix A, Figure 1). The sample <br />point for W08 was taken within the hardwood swamp community. <br />Dominant plant species identified at sample points completed within W08 consist of common buckthorn, <br />cottonwood, and American elm. Other common species identified in the wetland are listed on the data forms <br />included in Appendix C. The dominant species within the wetland are comprised mostly of hydrophytic <br />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. No Primary <br />Hydrology Indicators were observed. Secondary indicators of wetland hydrology observed included D2 and <br />D5. Therefore, the wetland hydrology criterion was met. <br />Soils within the wetland are mapped by the NRCS as Udorthents, wet substratum, Urban land -Lino <br />complex, and Seelyeville muck (Appendix A, Figure 2). The soils observed at the sample points were <br />generally consistent with the Lino series characteristics. Field indicators of hydric soil identified at sample <br />point W08-1w consisted of NRCS field Indicator A11-Depleted Below Dark Surface. Therefore, the hydric <br />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 hardwood swamp and shallow open water <br />wetland community dominated by cottonwood and American elm to a mesic forest upland community <br />dominated by buckthorn; 2) Transition from an area exhibiting wetland hydrology indicators within the <br />wetland to a lack of wetland hydrology indicators within the adjacent upland; and 3) Transition from soils <br />exhibiting hydric soil indicators to soils lacking indicators of hydric soil conditions. The transition from <br />wetland to upland characteristics generally correlated with a well-defined topographic break. <br />3.4 UPLANDS <br />Upland within the Project primarily consisted of a paved walking trail and maintained lawn with woody <br />vegetation growing along the edge of the wetland. Dominant vegetation in this area was comprised of <br />ground ivy, Kentucky bluegrass, quack grass, beggar's lice, boxelder, cottonwood, and buckthorn. The <br />upland communities across the project were prominently defined by the change in topography. <br />In general, upland areas were determined to be non -wetland based on the lack of wetland hydrology, hydric <br />soils, hydrophytic vegetation, and a location in areas higher in the landscape that lacked suitable <br />geomorphic position for wetland conditions to exist. <br />3.5 OTHER ENVIRONMENTAL CONSIDERATIONS <br />This report is limited to the identification of state and/or federally regulated wetlands within the Study Area. <br />However, there may be other regulated features within the Study Area, including, but not limited to, historical <br />or archeological features, endangered or threatened species, navigable waters, shoreland zones, and/or <br />floodplains, etc. Federal, state, and local units of government and regional planning organizations may have <br />regulatory authority to control or restrict land uses within or in close proximity to these features. <br />
