ABSTRACT Svoboda Ecological Resources (SER) visited the above referenced property on September 29, 2011 to examine the site for the presence of areas meeting wetland criteria. The study parcel is located within the City of Orono, Hennepin County Minnesota, (Figure 1). Two wetlands, connected by a drainage way, were delineated at this site. One sample transect was established along each of the two wetland boundaries and drainage way in order to characterize the soil, vegetation, and existing hydrology within the wetland-to-upland transition zones. The two delineated wetlands had similar vegetation and moisture regimes so they were delineated as one wetland complex given that they are connected by a drainage way. INTRODUCTION The subject parcel is approximately 3.9 acres in size with a single family home located at the southeast portion of the property. The site is dominated by gasses, hardwood trees and some scrub-shrub vegetation throughout. Manicured lawn is noted near the home. A drainage way extends between the two delineated wetlands within the forested area. The topography of the site is mostly flat within the wetland areas and has minor undulations throughout the upland. The upland gradually declines in slope toward the wetland areas. 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 wefland 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. Svoboda Ecological Resources 2900 Deer Run Trail Project No.:2011-026 1 Marcia Hammond
