Anderson Engineering of MN, LLC. Floyd Property-Wetland Investigation#13593 September 13,2013 Resource Review The following resources were reviewed to supplement the wetland field delineation: National Wetlands Inventory: The National Wetlands Inventory (Appendix A. Figure 2) identifies two wetlands within the project area. The NWI identifies the wetlands as: • One Type 5, L1 UBGH, Open water wetland • One Type 4, PEMF, Deep Marsh Natural Resources Conservation Service Soil Survey: The Soil Survey of Hennepin County, MN (Appendix A. Figure 3) does identify one hydric soil, Muskego muck, within the project area. Minnesota Department of Natural Resources Public Water Inventory: The MN DNR PWI for Hennepin County, MN (Appendix A. Figure 4), identifies Ferndale Marsh (27-852 P)within the north and east portions of the project area. Antecedent Precipitation Data: A review of the antecedent precipitation data collected from the University of Minnesota Climatology Working Group (Appendix D) indicate that precipitation totals for the previous weeks were slightly below average in Hennepin County and hydrologic conditions were suitable for completing an accurate wetland determination and boundary delineation. Field Review Two wetland basins were field delineated within and adjacent to the project area: Wetland 1: Wetland 1 consists of a Type 5, PUBG, open water wetland totaling approximately 0.22 acres. The wetland was dominated by common spike-rush (Eleocharis palustris), reed canary grass (Phalaris arundinacea) and common duckweed (Lemna minor). The underlying soils are mapped as Muskego muck. The investigated soil profile met the Depleted Below Dark Surface (A11) indicator. Indicators of wetland hydrology included saturation at the surface (A3), the FAC-Neutral Test (D5) and geomorphic position (D2). Wetland 1 is an excavated pond that receives hydrology from the surrounding upland areas. Wetland 1 appears isolated. The Minnehaha Creek Watershed District classifies this wetland as a Preserve. Wetland 2: Wetland 2 consists of a Type 4, PEMF, deep marsh, totaling approximately 2.07 acres on-site. The wetland continues off-site to the north and east. The wetland was dominated by green ash (Fraxinus pennsylvanica), common buckthorn (Rhamnus cathartica), reed canary grass (Phalaris arundinacea) and narrow-leaf cat-tail (Typha angustifolia). The underlying soils are mapped as Muskego muck. The investigated soil profile met the Histosol indicator (A1). Indicators of wetland hydrology included saturation at the surface (A3), the FAC-Neutral Test(D5)and geomorphic position (D2). s q E
