r r <br /> Introduction <br /> On May 2nd, 2013 Arrowhead Environmental Consulting (AEC) performed a wetland <br /> delineation at the 3710 Togo Road property located in Orono, MN. The legal description <br /> of the project location is: A part of the SW '/ of Section 17, TI 17N, R23W, Hennepin <br /> County, Orono, Minnesota. The parcel is a total of 0.38 acres (according to the Hennepin <br /> County Website). <br /> Methods <br /> AEC utilized the 1987 US Army Corps of Engineers Wetlands Delineation Manual and <br /> Midwest Regional Supplement to perform the wetland delineation. A United States <br /> Geological Survey (USGS) Map (Excelsior Quad) (Figure 1), the Minnesota Department <br /> of Natural Resources (MN DNR) Public Water Inventory (PWI) Map (Figure 2), the <br /> Hennepin County Soil Survey Map (Figure 3), the National Wetland Inventory (NWI) <br /> Map (Figure 4), and the MCWD Wetland Assessment Map (Figure 5) were reviewed <br /> prior to the site visit and used in the delineation process. The delineated wetland <br /> boundaries (GPS located) are indicated on Figure 6 and are overlaid on a 2012 aerial <br /> image. AEC used the routine delineation method. <br /> Wetland classification followed methods described by the USACOE - St. Paul District; <br /> Eggers and Reed "Wetland Plants and Plant Communities of MN and WI". The Circular <br /> 39 and Cowardin et al. classifications are given as well. The indicator status of plants <br /> was determined using the State of Minnesota— 2012 National Wetlands Plant List Final <br /> Ratings provided by the U.S. Army Corps of Engineers, Cold Regions Research and <br /> Engineering Laboratory. <br /> Pink pinflags were used to delineate the wetlands and were numbered sequentially; <br /> flagging was hung from adjacent vegetation to aid in location of the pinflags. Sample <br /> points were taken to document the vegetation, soils, and hydrology indicators within <br /> representative upland and wetland locations. <br /> Results <br /> Office Results <br /> Wetland 1 is indicated on the NWI map as a PEMF wetland. Wetland 1 is mapped in the <br /> Houghton soil series; the Houghton soil series is classified as a hydric soil (SCS Hydric <br /> Soils of the United States). Wetland 1 is indicated on the Minnesota Department of <br /> Natural Resources Public Water Inventory Map (PWI) as basin 915W. Wetland 1 is <br /> indicated on the MCWD Wetland Assessment Map as a Manage 3 Wetland. <br /> Field Results <br /> Wetland 1 <br /> AEC classified Wetland 1 as a Shallow Marsh (Type 3, PEMF) wetland. Wetland 1 is <br /> dominated by reed canary grass (Phalaris arundinacea) and cattail (Typha). The <br /> adjacent upland area is dominated by boxelder (Acer negundo), red oak (Quercus <br /> macrocarpa), honeysuckle(Lonicera tatarica), and hazel(Corylus americana). <br /> I <br />
