Geographically,the area is located in Section 21,Township 117 North, Range 23 West. One Type 1, PF01 A,seasonally flooded basin was identified and delineated within the project area.Wetland 1 is located entirely within the project area and is approximately 0.21 acres in size. WETLAND ASSESSMENT 2709 WALTERS PORT LANE&2710 PENCE LANE ORONO,MN APRIL 2017 MAPLE CREST LANDSCAPE BACKGROUND&METHODOLOGY Backaround As requested by Maple Crest Landscape, Anderson Engineering of MN, LLC completed a wetland investigation at the specified project area located at 2709 Walters Port Lane&2710 Pence Lane, in the City of Orono, Minnesota. Geographically, the sites are located in Section 21, Township 117 North, Range 23 West. The wetland delineation was completed in accordance with the 1987 United States Army Corps of Engineers Wetland Delineation Manual and the published regional supplement to the Army Corps Wetland Delineation Manual, Midwest Region. The purpose of this study was to investigate the project area, identify areas meeting the technical criteria for wetlands, delineate the jurisdictional extent of the wetland, and classify the wetland habitat. Fieldwork for this site investigation was completed by Environmental Associate Tina Justen and GIS Specialist Joe Aden on April 5, 2017. The weather was partly cloudy with a temperature of 50 degrees Fahrenheit. Methodology United States Geologic Service 7.5"Topographic Quadrangle maps, United States Fish and Wildlife Service National Wetland Inventory maps, United States Department of Agriculture Natural Resources Conservation Service Soil Survey and available aerial photographs were consulted to initially locate potential wetland habitats. Routine On-site Determination Method was used during this investigation. In this method, the following procedures were used: 1) The vegetative community was sampled in all present strata to determine whether it met hydrophytic vegetation criteria based on the indicators identified in the Midwest Regional Supplement. 2) Soil pits were dug using a Dutch auger to depths of at least 24". Soil profile was noted, in addition to any hydric soil characteristics. 3) Signs of wetland hydrology were noted and compared to field criteria such as depth to shallow water table and depth of soil saturation found in the soil pits. Data from sample points were recorded on Army Corps of Engineers Midwest Region Wetland Determination Data Forms (Appendix B). At least one sample point transect crosses the delineated wetland edge. This transect consist of an upland sample point and a wetland sample point. Other sample points may be located in areas which have one or more of the wetland vegetation, soils, or hydrologic characteristics present; where questionable conditions exist;or to verify the absence of wetland criteria. Photographs are also taken at each sample point, and of the wetland and upland buffer(Appendix C). Sample points were marked in the field with orange flags.The identified wetland boundary was marked with sequentially numbered pink flags. All sample points and the delineated wetland boundary were located utilizing a Trimble Geo XH sub-meter GPS unit. WETLAND ASSESSMENT 2709 WALTERS PORT LANE&2710 PENCE LANE ORONO,MN APRIL 2017 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 (Appendix A. 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&2710 PENCE LANE ORONO, MN APRIL 2017 MAPLE CREST LANDSCAPE FIELD REVIEW Field Review Wetland 1: Wetland 1 is a Type 1, PF01A, seasonally flooded basin. There is no discernable outlet; this basin appears to be hydrologically isolated. Overall, the wetland vegetation is dominated by reed canary grass (Phalaris arundinacea) and American elm (Ulmus americana). The underlying soils are mapped as Muskego, Blue Earth and Houghton soils (1-16A). The investigated soil profile met the redox dark surface (F6) hydric soil indicator. Hydrology indicators observed include saturation (A3), geomorphic position (D2), and the FAC-Neutral Test(D5). The upland buffer surrounding the wetland is a manicured lawn primarily vegetated with wood violet(Viola sororia), staghorn sumac (Rhus typhina), burr oak (Quercus macrocarpa), and sugar maple (Acer saccharum). The transition between the upland and the wetland varies between gentle slopes and steep slopes. The project area is located adjacent to Lake Minnetonka. The shoreline associated with the project area is bound by riprap and steel sheet piling. WETLAND ASSESSMENT 2709 WALTERS PORT LANE&2710 PENCE LANE ORONO,MN APRIL 2017 MAPLE CREST LANDSCAPE CONCLUSION Conclusion One wetland was identified and delineated in accordance with the 1987 United States Army Corps of Engineers Wetland Delineation Manual within the project area located at 2709 Walters Port Lane & 2710 Pence Lane, Orono, Minnesota. The wetland in the project area may be regulated by several agencies at the local, State, and/or federal level. Activities which may potentially impact those wetlands identified within this report should be discussed in advance with the appropriate regulating agency in regards to potential permit requirements. The Local Government Unit (LGU) responsible for implementing the Minnesota Wetland Conservation Act at this project location is the Minnehaha Creek Watershed District(MCWD). The Minnehaha Creek Watershed District inventory classifies Wetland 1 as a Manage 3 wetland. The MCWD and the City of Orono have wetland buffer and shoreline setback requirements. Please coordinate directly with the regulatory agencies regarding the requirements for this specific wetland and project. This wetland investigation meets the standards and criteria described in the 1987 United States Army Corps of Engineers Wetland Delineation Manual all applicable subsequent guidance for an on-site determination and the results reflect the conditions present at the time of the delineation. 1 certify that 1 performed the field analysis and wrote the report for this wetland determination.
