1L <br /> Introduction <br /> On November 19`h, 2012 Arrowhead Environmental Consulting (AEC) performed a <br /> wetland delineation at the 825 Willow Drive property located in Orono, MN. The legal <br /> description of the project location is: A part of the NW `/ of Section 10, TI 17N, R23W, <br /> Hennepin County, Orono, Minnesota. The parcel is a total of 0.82 acres(according to the <br /> Hennepin 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 PEMC wetland. Wetland 1 is mapped in the <br /> Cordova and Houghton soil series; the Cordova and Houghton soil series are classified as <br /> hydric soils (SCS Hydric Soils of the United States). Wetland 1 is indicated on the <br /> Minnesota Department of Natural Resources Public Water Inventory Map (PWI) as basin <br /> 27-140P (French Marsh). Wetland 1 is indicated on the MCWD Wetland Assessment <br /> Map as a Preserve 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)with scattered <br /> boxelder (Acer negundo) and gray dogwood (Cornus racemosa) along the fringe of the <br /> 1 <br />
