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 cons dered 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 all 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 (NWI) maps (Figure 2), Web Soil Survey of Hennepin County map (Figure 3), Minnesota Public Waters Inventory maps (Figure 4), and 2012 aerial photographs were reviewed prior to the site visit to identify areas that may be wetlands. Areas illustrating evidence of wetlafnd 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 wtland-to-upland transition zones in order to characterize the vegetation, soils, and hydrology of the site. Transects consist of a representative upland sample point and representative wetl nd sample point. Information obtained at the sample points can be found on the field data sheet located in the Technical Documents 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. Wetlands were classified in accordance with methods described by Cowatdin 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 Documents section, was determined using the National List of Plant Species That Occur in Wetlands — Region 3 (Sabine 1999). RESULTS The National Wetlatnd Inventory indicates a wetland of type PUBG in the survey area. (Figure 2). The Web Soil Survey of Hennepin County (Figure 3) identifies six soil map units present on the subject property. They are as follows: Klossner soils, depressional; Hamel-Glencoe, depressional, compex; Hamel, overwash-Hamel complex; Lester loam, morainic; and two Lester-Kilkenny complex types of different slopes. The Klossner type is the hydric soil on the site. The Hamel-Glencoe complex is predominantly hydric. The Hamel, overwash-Hamel complex is partially hydric and the remaining Lester loam and complexes are predominantly non-hydric. Soil series descriptions are provided in the Technical Documents section. Svoboda Ecological Resources 2 30 and 20 Orono Orchard Rd Project Number: 2013-024 Orono,MN
