Plants were identified using standard regional plant keys. Taxonomy and indicator status of <br /> plant species was taken from the 2014 National Wetland Plant List (Lichvar, R.W. and Kartesz, <br /> J.T. 2009. North American Digital Flora:National Wetland Plant List, version 2.4.0 <br /> (https://wetland�lants.usace.army.mil). U.S. Army Corps of Engineers, Engineer Research and <br /> Development Center, Cold Regions Research and Engineering Laboratory, Hanover,NH, and <br /> BONAP, Chapel Hill, NC.) <br /> III. RESULTS <br /> Review of NWI. Soils, and DNR Information <br /> The National Wetland Inventory Map (NWI) (Excelsior Quadrangle, MN DNR 2013) showed <br /> one PEM 1 C/L2ABH wetland/waterbody within the property(Figure 3). <br /> The Soil Survey of Hennepin County,Minnesota <br /> (http://soils.usda.gov/survey/geography/ssurgo/) showed Tadkee as the hydric soil type present <br /> within the review area. A soils map indicating the soil types present within the parcel is included <br /> on Figure 4 <br /> The DNR Public Waters Map,Hennepin County(http://deli.dnr.state.mn.usn showed DNR <br /> Public Water 27-133P (Lake Minnetonka)within 1000' of the properly (Figure 5). <br /> The National Hydrography Dataset Map (USGS) showed Lake Minnetonka bordering the <br /> property to the east (Figure 6). <br /> Wetland Determinations and Delineations <br /> Potential wetlands were evaluated in greater detail during field observations on July 7, 2015. <br /> One(1) wetland was identified within the subject parcel (Figure 2). Corresponding data forms <br /> are included in Appendix A. The following description of the wetland and its adjacent upland <br /> reflects conditions observed at the time of the field visit. At that time precipitation totals were <br /> greater than typical based on available 30-day rolling precipitation data and normal based on the <br /> three-month antecedent conditions (April, May, June) (Appendia�B). <br /> Wetland 1 was a Type 3 (PEM 1 C) shallow marsh. The wetland was dominated by a fringe of <br /> reed canary grass,pinkweed, and jewelweed with cattail present along the water's edge of Lake <br /> Minnetonka. Saturation was observed at the surface of the sample point location with free water <br /> observed 6"below the soil surface. <br /> Adjacent upland at the sample location was dominated by sugar maple,basswood, and ironwood <br /> trees with a sparse herbaceous layer consisting of early meadow rue and common buckthorn. <br /> The delineated boundary followed an abrupt change in topography and was placed along the <br /> transition zone from wetland to upland plant communities, where hydrology indicators were no <br /> longer present, and the transition from hydric to non-hydric soils. Wetland 1 was indicated on <br /> the NWI map as a PEM 1 C/L2ABH wetland/waterbody and was located in an area of mapped <br /> Tadkee(hydric) on the soil survey. <br /> 3 <br />
