MAPLE CREST LANDSCAPE RESOURCE REVIEW 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 one PF01A wetland within the project area. USDA-Natural Resources Conservation Service Soil Survey: Soil Survey data for Hennepin County, MN were obtained and reviewed prior to the delineation. Table 1 provides a list of the mapped soils within the investigation area. Figure 3 in Appendix A contains a map of the soil units with percent hydric components.

Minnesota Department of Natural Resources Public Water Inventory: The MN DNR PWI for Hennepin County, MN (AppendixA. Figure 4)identifies Lake Minnetonka, adjacent to the southwest boundary of the parcel. Antecedent Precipitation Data: An analysis of the University of Minnesota Climatology Working Group's 30 day rolling precipitation data for the previous three months(Appendix D) indicate that precipitation totals for previous weeks were below the normal monthly range for this project area, but trending towards normal. Hydrologic conditions were suitable for completing an accurate wetland determination and boundary delineation. WETLAND ASSESSMENT 2709 WALTERS PORT LANE 8c 271 O PENCE LANE ORONO, MN APRIL 2017
