ABSTRACT Svoboda Ecological Resources (SER) visited the above referenced property on November 1, 2011 to examine the site for the presence of areas meeting wetland criteria. The study parcel is located within the City of Orono, Hennepin Counry Minnesota, (Figure 1). Two wetlands were delineated at this site. One sample transect was established along each of the two wetland boundaries in order to characterize the soil, vegetation, and existing hydrology within the wetland-to-upland transition zones. INTRODUCTION The subject parcel is approximately 0.8 acres in size with a single family home located in the central portion of the property. The site is dominated by manicured lawn, wild grasses, hardwood trees and some scrub-shrub vegetation throughout. The topography of the site is mostly flat within the upland areas and has a slight decline in to the wetland area. The surrounding land use consists mostly of single-family homes. The identified wetlands were classified according to the Cowardin et al., the Circular 39 and the Eggers and Reed classification systems and marked with pink "Wetland Delineation" pin flags. Please find within the Technical Documentation Section; 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 wetland 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 Documentation 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 increase the regional sensitivity of wetland-delineation methods (National Research Svoboda F.cological Resources 1 165 Fendale Road Project No.:2014-026 1 Robert Brook
