"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 Council 1995).The intent of this supplement is to bring the Corps Manual up to date with current knowledge and practice in the region and not to change wetland boundaries." "...This Regional Supplement is designed for use with the current version of the Corps Manual (Environmental Laboratory 1987) and ail subsequent versions. Where differences in the two documents occur, this Regional Supplement takes precedence over the Corps Manual for applications in the Midwest Region." National Wetland Inventory (NW� maps (Figure 2), Web Soil Survey of Orono and Hennepin County maps (Figure 3), Minnesota Protected Waters maps (Figure 4), and 2010 aerial photographs were reviewed prior to the site visit to identify areas that may be wetlands. Areas illustrating evidence of wetland conditions were examined in greater detail during the field survey. Vegetation, soils and hydrology were examined (as outlined in the 1987 Manual) and used to characterize wetland types and determine wetland boundaries. Sample transects were established in representative wetland-to-upland transition zones in order to characterize the vegetation, soils, and hydrology of the site. Transects consisted of a representative upland sample point and a representative wetland sample point. Information obtained from the sample points can be found on the field data sheets located in the Technical Documentation Section. Wetland boundaries were marked at the site by pink "Wetland Delineation" pin flags. The wetland boundary is considered to be the topographically highest extent of the wetland basin; areas below the staked boundary met the three required wetland criteria while areas above were lacking in one or more of these criteria. Wetland classification followed methods described by Cowardin et al. (1979) and used in the NWI (e.g. PEMB, PSS1C, etc.), completed by the U.S. Fish and Wildlife Service. The Circular 39 and Eggers and Reed classification systems are also given. The indicator status of plants, as described in The Technical Documentation Section, was determined using the National List of Plant Species That Occur in Wetlands — Region 3 (Sabine 1999). RESULTS Background Information-(Office-Based Investigation) The NWI map (Excelsior Quadrangle) illustrates two National Wetland Inventory wetlands (one PEMF and one PEM/SS 1 C)present within the property boundary(Figure 2). The Web Soil Survey of Orono and Hennepin County classifies two soil complexes and two other individual soil series' present on the subject properiy (Figure 3). One mapped complex and one individual soil series was classified the "hydric" soil. The other mapped soil complex and Svoboda Ecological Resources 2900 Deer Run Trail Project No.:2011-026 2 Marcia Hammond
