ABSTRACT <br /> Svoboda Ecological Resources (SER) visited the above referenced property to examine the site <br /> for the presence of areas meeting wetland criteria. The wetland boundaries were flagged on <br /> April 23, 201 S and field data was collected on May 6, 201 S. The study parcel is located in the <br /> city of Orono, MN in Hennepin County (Figure 1). Two wetland boundaries were delineated at <br /> this site. One sample transect was established along the boundary of each wetland area in order <br /> to characterize the soil, vegetation, and existing hydrology within the wetland-to-upland <br /> transition zone. <br /> INTRODUCTION <br /> The subject parcel is approximately 5.76 acres and is dominated by altered/non-native deciduous <br /> forest as well as mixed short grasses. Two wetlands present on the property were delineated. The <br /> topography of the site is rolling with a small group of houses and structures present on the top of <br /> the hill. The surrounding land use is moderately spaced single family homes. Long Lake is <br /> located adjacently south and a golf course is to the north. The identified wetlands were classified <br /> according to the Cowardin et al., the Circular 39 and the Eggers and Reed classification systems <br /> and marked with pink "Wetland Delineation" pin flags and orange flagging tape. The Technical <br /> Documents section of this report contains field data sheets, plant indicator status information, <br /> 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 /> � wetland boundaries." "...This Regional Supplement is designed for use with the <br /> Svoboda Ecological Resources 1 1025 Spring Hill Rd <br /> Project Number: 2015-007-03 Orono,MN <br />
