<br />Pinnacle Engineering, Inc. Wetland Determination Report <br />11541 95th Avenue North Hamm Property <br />Maple Grove, MN 55369 May 24, 2021 <br />763-315-4501 Page 7 Pinnacle Project Number: EM20212672 <br />grass and cattails. Hydric soils were found to present. The wetland is located at the toe <br />of adjacent steep slopes of upland areas that surround the wetland basin. The wetland <br />edge was determined on the southern edge of the wetland and followed the topography <br />and elevation of the slopes from the upland area to the wetland basin. Wetland 3 extends <br />to the northeast beyond the Site boundary. <br /> <br />Wetland 4 is a basin located in the northwestern portion of the of northern area of interest. <br />Under the Cowardin system Wetland 4 would be considered a palustrine, emergent, <br />persistent, temporary flooded (PEM1A) basin. The surrounding upland areas drain into <br />the wetland basin. A swale appears to drain the basin to the southwest during large <br />rainfall events. Under the Circular 39 system, Wetland 4 is considered a Type 2 wetland. <br />Wetland 2 is dominated by hydrophytes primarily comprised of reed canary grass. Hydric <br />soils were found to be present. The wetland edge was determined on the southern edge <br />of the wetland and followed the vegetation change along the wetland basin. <br /> <br />Wetland 5 is a small basin located in the southwestern portion of the of southeastern <br />property. Under the Circular 39 system, Wetland 3 is considered a Type 3 wetland. <br />Under the Cowardin system Wetland 3 would be considered a palustrine, emergent, <br />persistent, seasonally flooded (PEM1C) basin. Wetland 3 is dominated by hydrophytes <br />comprised of lake sedge, reed canary grass, and cattails. Hydric soils were found to <br />present. The wetland is located at the bottom of steep slopes of adjacent upland areas <br />that surround the wetland basin. The wetland edge was determined on the northern edge <br />of the wetland and followed the topography and elevation of the slopes from the upland <br />area to the wetland basin. Wetland 5 extends to the south beyond the Site boundary. <br /> <br />The Local Governmental Unit (LGU), the DNR, and U.S. Army Corps of Engineers will <br />determine the jurisdictional wetland status of the identified wetland areas. <br /> <br /> <br />5.0 CONCLUSION <br /> <br />Pinnacle performed a Level 2, On-Site, Wetland Delineation of three parcels of land <br />located at 485 Orono Orchard Road South in Orono, Minnesota. The three parcels are <br />located near the northern shore of Lake Minnetonka and total approximately 22.6 acres. <br />The level 2 delineation was conducted in substantial conformance with the 1987 U.S. <br />Army Corps of Engineers Wetland Delineation Manual, updated February 25, 1997, and <br />utilized the Midwest Regional Supplement. <br /> <br />During the field assessment, it was determined that five areas within the Site met all three <br />of the mandatory criteria of a wetland. The wetland boundaries were recorded utilizing a <br />handheld GPS device and were flagged for survey by Sunde Land Surveying. The <br />delineation will be reviewed by the Minnehaha Creek Watershed District which serves as <br />the LGU administering Minnesota’s Wetland Conservation Act and the U.S. Army Corps <br />of Engineers, which administers the Clean Water Act <br /> <br /> <br /> <br />350
