cathartica), ironwood (Ostrya virginiana), green ash (Fraxinus pennsylvanica), bur oak (Quercus macrocarpa), and basswood(Tilia Americana). The wetland boundary was placed along the vegetation transition zone; there was an abrupt shift in vegetation between the sedge and loosestrife (hydrophytic) and the common buckthorn (non-hydrophytic). A mild topographic break was observed along the wetland boundary; the boundary was placed at or near the foot of the slope. Additionally, soil was saturated at the surface and water was observed at 12" below the soil surface within the wetland sample point; the soil was saturated at 16" and water observed at 26" below the soil surface in the upland sample point. According to the City of Orono and Minnehaha Creek Watershed District, the wetland is classified as a "Preserve" wetland; a Preserve wetland requires a 50' wetland buffer and 20' setback from the wetland buffer(total of 70'). Discussion One wetland basin was delineated within the subject parcel. Wetland 1 is described as a Shallow Marsh (Type 3, PEMC) wetland and is dominated by cattail, sedge, loosestrife, and willow. Wetland 1 was delineated by approximately 29 pinflags. In order to be official the wetland delineation must be reviewed and approved by the Local Government Unit (LGL� and potentially other agencies (Local, State, Federal). AEC recommends that the wetland boundary be located by a Professional Land Surveyor or located by a survey grade GPS unit. Any work within or adjacent to a wetland will require Wetland Conservation Act(WCA)permits (and potentially other permits). Please consult with AEC if you plan on filling, draining, excavating wetlands within your project location.
