(GES)was retained to delineate wetlands at a single-family residence located west of North Old Crystal Bay road and north of Fox Street in the City of Orono, Minnesota. The project area is located in part of the NE '/ SW '/ Section 4, T117N, R23W, Hennepin County, Minnesota (Figure 1). As shown on the U.S.G.S. Quadrangle map (Figure 2), the site is relatively flat but slopes down toward the west. On April 11, 2012, GES conducted an evaluation of the site, collecting data and delineating a wetland which runs north and south in the western portion of the lot as shown in Figure 3. Methodologies The wetland was delineated using the on-site methods contained in the "Routine Determinations" section of the U.S. Army Corps of Engineers "Wetlands Delineation Manual' (Technical Report Y-87-1, 1987), as well as "Regional Supplement to the Corps of Engineers Wetlands Delineation Manual: Midwest Region" (U.S. Army Corps of Engineers, 2010). These are the methodologies currently used to determine wetlands by the U.S. Army Corps of Engineers for implementation of Section 404 of the Clean Water Act and by Local Government Units under the Wetland Conservation Act. GES classified the wetland under the U.S. Fish and Wildlife Service (FWS) Cowardin system, Circular 39 and Eggers and Reed methodologies.
