ABSTRACT Svoboda Ecological Resources (SER) visited the above referenced property on 4/27/12 to examine the site for the presence of areas meeting wetland criteria. The study parcel is located in the city of Orono, MN in Hennepin County (Figure 1). One wetland boa�ndary was delineated at this site. One sample transect was established along the boundary in order to characterize the soil, vegetation, and existing hydrology within the wetland-to-upland transition zone. INTRODUCTION The subject parcel is approximately 10.2 acres and is dominated by turf grass and early successional mesic forest. The topography of the site slopes gradually from north to south. The surrounding land use is primarily single family homes. The identified wetlands were classified according to the Cowardin et al., Circular 39 and Eggers and Reed classification systems and marked with pink "Wetland Delineation" pin flags. The Technical Documents section of this report contains field data sheets, plant indicator status information, soil survey information, and wetland definition information. METHODS The methods used to delineate the subject parcel are as described in the 1987 US Army Corps of Engineers Wetlands Delineation Manual and the 2010 Midwest Regional Supplement Manual. In the 1987 Manual, the methods used were described under the "routine" methods for sites less than 5 acres. This methodology is followed in order to assess whether the three parameters of a wetland are met for areas on the subject parcel. The three parameters required under normal circumstances in order to delineate a wetland are described in the Technical Documents section. The Midwest Regional Supplement Wetland Delineation Manual is also being utilized to increase the accuracy of our wetland boundaries. This addendum to the original 87 Manual was created to address the many regional differences that affect wetlands and the delineation methods used throughout the country. The following explanations are passages from that document. "This Regional Supplement is part of a nationwide effort to address regional wetland characteristics and improve the accuracy and efficiency of wetland- delineation procedures. Regional differences in climate, geology, soils, hydrology plant and animal communities, and other factors are important to the identification and functioning of wetlands. These differences cannot be considered adequately in a single national manual. The development of this supplement follows National Academy of Sciences recommendations to inerease the regional sensitivity of wetland-delineation methods (National Research Svoboda Ecological Resources 1685 Fox Street Project Number. 2012-01 1 1 Orono MN
