Pinnacle Engineering, Inc. Wetland Determination Report 11541 95th Avenue North Hamm Property Maple Grove, MN 55369 May 24, 2021 763-315-4501 Page 5 Pinnacle Project Number: EM20212672 Wetland Type L2UBH The NWI Cowardin wetland classification system identifies the L2UBH label for a wetland that consists of all wetlands and deepwater habitats wetlands situated in a topographic depression and total area of at least 20 acres. Similar wetlands and deepwater habitats totaling less than 20 acres are also included in the Lacustrine System if an active wave- formed or bedrock shoreline feature makes up all or part of the boundary, or if the water depth in the deepest part of the basin equals or exceeds 8.2 feet at low water. This classification applies to Wetland 1 which corresponds to Lake Minnetonka and is identified on the NWI map. The soil survey did not indicate hydric soils are located within the Wetland 1 area. Wetland Type PEM1A The NWI Cowardin wetland classification system identifies the PEM1A label for a wetland that consists of a palustrine basin, dominated by persistent emergent vegetation, consisting of erect, rooted, herbaceous hydrophyte species that normally remain standing at least until the beginning of the next growing season, that is temporarily flooded. Surface water is present for brief periods during the growing season, but the water table usually lies well below the ground surface for most of the season. This classification applies to wetlands 2 and 4. Wetlands 2 and 4 are mapped on the NWI map. The soil survey did not indicate hydric soils located within these wetland areas. Wetland Type PEM1C The NWI Cowardin wetland classification system identifies the PEM1C label for a wetland that consists of a palustrine basin, dominated by persistent emergent vegetation, consisting of erect, rooted, herbaceous hydrophyte species that normally remain standing at least until the beginning of the next growing season, that is seasonally flooded. Surface water is present for extended periods especially early in the growing season but is absent by the end of the growing season in most years. The water table after flooding ceases is variable, extending from saturated to the surface to a water table well below the ground surface. The NWI map for the Site area indicated one PEM1C wetland contained within the Site boundaries, which corresponds to Wetlands 3. The soils survey did indicate hydric soils located within the Wetland 3 area. 4.0 DISCUSSION Pinnacle conducted a Level 2, On-Site, Wetland Delineation of three parcels of land located at 485 Orono Orchard Road South, 1401 Orono Road and 1391 Fox Street in Orono, Minnesota. The three parcels are located near the northern shore of Lake Minnetonka and total approximately 24.44 acres (Site). The proposed project area is within the N ½ of SW ¼ of Section 30, Township 23N, Range 27W (Lat: 44.968781°, Long: -93.560311°). The northern property extends from near the intersection of Orono Orchard Road South and Shoreline Drive north to the northern property boundary. The eastern property 348
