Introduction On September 4`h, 2008, Svoboda Ecological Resources (SER) completed a field investigation of the subject property to identify and delineate areas meeting wetland criteria in accordance with the 1987 Army Corps of Engineers Wetland Delineation Manual. As depicted in (Figure 1), the site is located in the city of Orono. The approximate 1.3 acre site has the following legal description in the City of Orono, Hennepin County, Minnesota.: • Located in part of the of Sec. 2, Twp. 1 l 7, Rng. 23 W Methods The USGS Topographic Map (Figure 1), Hennepin County Soil Survey (Figure 2), National Wetland Inventory Data (Figure 3), the Department of Natural Resources Protected Waters Inventory (Figure 4), and aerial photographs were reviewed prior to the field investigation to identify potential wetland habitats for investigation. The parcel boundary was determined using a property description given by the owner and GIS data avaiiable from the county. The following procedures were used to determine wetland habitats: • The vegetation was sampled to determine whether greater than 50% of the dominant plant species were classified as either obligate wetland, facultative wetland, or facultative. • Shallow soil pits were hand dug with a soit auger to identify soil morphology, redoximorphic features and soil texture. • Wetland hydrology indications were observed through open soil pits, shallow water table measurements, and historical data. The wetland hydrology determination uses the criteria of the presence of water within 12 inches of the surface for 14 days during the growing season, or within 24 inches of the surface during the dry part of the growing season. No jurisdictional wetland boundaries were delineated on site. Data for two sample points were taken in questionable areas. Data sheets for the recorded transect are located in the Appendix.
