ABSTRACT <br /> Svoboda Ecological Resources (SER) visited the above referenced property on 11/23/13 to <br /> examine the site for the presence of areas meeting wetland criteria. The study parcel is located in <br /> the city of Orono, MN in Hennepin County (Figure 1). Two wetland boundaries were delineated <br /> at this site. One sample transect was established along the western boundary of the eastern <br /> wetland area and one along the eastern side of the western wetland in order to characterize the <br /> soil, vegetation, and existing hydrology within the wetland-to-upland transition zone. <br /> INTRODUCTION <br /> The subject parcel at 835 Hunt Farm Rd is approximately 3.37 acres. The parcel is an upland <br /> woodlands, with a few open grassy areas and a ditch running between the two wetlands on the <br /> east and west sides. The ditch becomes an excavated (but currently dry) pond on the east side of <br /> the property. The topography of the site is rolling and elevated between the two wetlands. <br /> Numerous huge boulders are present on the lot along with many patches of reed canary grass. <br /> The surrounding land use is primarily widely spaced single family homes and wetlands. The <br /> identified wetlands were classified according to the Cowardin et al., the Circular 39 and the <br /> Eggers and Reed classification systems and marked with pink "Wetland Delineation" pin flags. <br /> The Technical Documents section of this report contains field data sheets, plant indicator status <br /> information, soil survey information, and wetland definition information. <br /> METHODS <br /> The methods used to delineate the subject parcel are as described in the 1987 US Army Corps of <br /> Engineers Wetlands Delineation Manual and the 2010 Midwest Regional Supplement Manual. In <br /> the 1987 Manual, the methods used were described under the "routine" methods for sites less <br /> than 5 acres. This methodology is followed in order to assess whether the three parameters of a <br /> wetland are met for areas on the subject parcel. The three parameters required under normal <br /> circumstances in order to delineate a wetland are described in the Technical Documents section. <br /> The Midwest Regional Supplement Wetland Delineation Manual is also being utilized to <br /> increase the accuracy of our wetland boundaries. This addendum to the original 87 Manual was <br /> created to address the many regional differences that affect wetlands and the delineation methods <br /> used throughout the country. The following explanations are passages from that document. <br /> "This Regional Supplement is part of a nationwide effort to address regional <br /> wetland characteristics and improve the accuracy and efficiency of wetland- <br /> delineation procedures. Regional differences in climate, geology, soils, <br /> hydrology plant and animal communities, and other factors are important to the <br /> identification and functioning of wetlands. These differences cannot be <br /> considered adequately in a single national manual. The development of this <br /> supplement follows National Academy of Sciences recommendations to increase <br /> the regional sensitivity of wetland-delineation methods (National Research <br /> Council 1995).The intent of this supplement is to bring the Corps Manual up to <br /> date with current knowledge and practice in the region and not to change <br /> Svoboda Ecological Resources 1 835 Hunt Farm Rd <br /> Project Number: 2013-040 Orono MN <br />
