This project area is in Section 32, Township 118 North, Range 23 West. Delineated aquatic resources or, portions thereof, was identified and delineated within the project area and summarized in Table 1 and depicted in Appendix A, Figure 5. Table 1.

BACKGROUND & METHODOLOGY WETLAND INVESTIGATION TOPO LLC 3505 WATERTOWN ROAD ORONO, MN May 24, 2022 Page 4 BACKGROUND As requested by Lorelei Ritter, Anderson Engineering of Minnesota, LLC completed a wetland investigation at 3505 Watertown Road located in Orono, Hennepin County, Minnesota (Appendix A, Figure 1). This project area is in Section 32, Township 118 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 Regional Supplement. The purpose of this study was to identify areas meeting the technical criteria for wetlands, delineate the jurisdictional extent of the wetland basins, and classify the wetland habitats in the project area. Fieldwork for this site investigation was completed by Dylan Kruzel and Wyatt Benton, on May 18, 2022. The weather was sunny and 70 degrees Fahrenheit. METHODOLOGY U.S. Geologic Service 7.5” Topographic Quadrangle maps, U.S. Fish and Wildlife Service National Wetland Inventory (NWI) maps, Minnesota Department of Natural Resources Public Water Inventory (PWI) maps, U.S. 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 sixteen to thirty-six inches. The 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 consists of an upland sample point and a wetland sample point. Other sample points may be in areas which have one or more other wetland criteria present; where questionable conditions exist; or to verify the absence of wetland criteria. Photographs of each resource is included in the resource review summary pages. Sample points were marked in the field with orange flags. The identified aquatic resource was marked with sequentially numbered pink flags and ribbon. All sample points and the delineated aquatic resource extent were located using a Trimble Geo XH sub-meter GPS unit. Delineated resources were evaluated using Board of Soil and Water Resource’s Minnesota Routine Assessment Method version 3.2 (MnRAM). Information from desktop and field assessment was evaluated in the system and a management classification ranging from exceptional quality to low quality is output as Preserve, Manage 1, Manage 2, and Manage 3. Resulting classifications are typically utilized in development planning. RESOURCE REVIEW WETLAND INVESTIGATION TOPO LLC 3505 WATERTOWN ROAD ORONO, MN May 24, 2022 Page 5 RESOURCE REVIEW The below described data were reviewed as part of the aquatic resource field delineation. A summary of each resource contained within the project area follows. NATIONAL WETLANDS INVENTORY The National Wetlands Inventory identifies one PEM1C wetland within the project area (Appendix A, Figure 2). USDA – NATURAL RESOURCES CONSERVATION SERVICE SOIL SURVEY Soil survey data for Hennepin County was obtained and reviewed prior to the delineation. Table 2 provides a list of the mapped soils in the project area. Figure 3 in Appendix A depicts USDA Natural Resources Conservation Service mapped soils within the project categorized by total percentage of hydric components. Table 2.

MINNESOTA DEPARTMENT OF NATURAL RESOURCES PUBLIC WATER INVENTORY The Minnesota Department of Natural Resources Public Water Inventory for Hennepin County does not identify public water in the project extent (Appendix A, Figure 4). 30-DAY ROLLING PRECIPITATION DATA A review of the 30-day rolling precipitation data collected from the University of Minnesota Climatology Working Group (Appendix D) indicates that precipitation totals for the weeks prior to the site visit were above the range of average in the general project area. The overall hydrologic conditions were suitable, however, for completing an accurate wetland determination and boundary delineation.

The wetland is dominated by reed canary grass and stinging nettle, with a shrub layer dominated by European buckthorn and a tree stratum dominated by green ash and boxelder. The wetland receives hydrology via a culvert to the north that runs under Watertown Road and overland flow from upland areas. The transition to upland was determined based on a lack of hydric soils and wetland hydrology. Upland areas were dominated by an herbaceous layer of eastern prickly gooseberry and garlic mustard, shrub stratum of European buckthorn and a tree stratum dominated by sugar maple and black walnut. ATYPICAL/PROBLEMATIC CONDITIONS Analysis of antecedent precipitation showed the 30-day rolling total was above the normal monthly average at the time of field visit, however, conditions were deemed suitable for delineation. CONSISTENCY WITH DESKTOP REVIEW NWI inventoried areas were found to be generally correct; however, additional wetland was identified bordering and north of the PEM1C basin. 1 Appendix B contains wetland determination data forms supporting this investigated resource: Wet Point(s): 1A Up Point(s): 1B 2 Appendix E contains MnRAM output CONCLUSION WETLAND INVESTIGATION TOPO LLC 3505 WATERTOWN ROAD ORONO, MN May 24, 2022 Page 7 CONCLUSION A total of one wetland, or portions thereof, was identified and delineated within the project area and in accordance with the 1987 United States Army Corps of Engineers Wetland Delineation Manual. Project area aquatic resources may be regulated by several agencies at the local, state, and/or federal level. Activities which may potentially impact wetlands should be discussed in advance with the appropriate regulating agency regarding potential permit requirements. The Local Government Unit (LGU) responsible for implementing the Minnesota Wetland Conservation Act at this project location is in the Minnehaha Creek Watershed District. The Watershed District may require vegetated buffers around all regulated wetland areas. Wetland buffers must meet the standards specified by the Watershed District for any project that is regulated under the Wetland Conservation Act. This wetland investigation meets the standards and criteria described in the 1987 United States Army Corps of Engineers Wetland Delineation Manual and all applicable subsequent guidance for an on-site determination. The results reflect the conditions present at the time of the delineation. I certify that I performed the field analysis and/or wrote the report for this wetland determination.

Graph of recent precipitation in comparison with the normal range of precipitation in the general site location. Daily precipitation data is plotted independently and as a 30-day rolling total up to the date of the site visit. The normal range is plotted from precipitation data recorded from 1981 to 2010. The normal range is represented in this graph with two lines, the 30th percentile and the 70th percentile of the period-of-record data distribution.
