i r 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 (NWn 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 detemune wetland boundaries if there were any. If wetlands are found on a property, a sample transect would be established in a representative wetland-to-upland transition zone in order to characterize the vegetation, soils, and hydrology of the site. Transects consist of a representative upland sample point and representative wetland sample point. The wetland boundary is considered to be the topographically highest extent of the wetland basin; areas below a staked boundary will meet the three required wetland criteria while areas above lack in one or more of these criteria. Wetland classification follows 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-Sased Investigation) The NWI map (Excelsior Quadrangle) illustrates no National Wetland Inventory wetlands present within the property boundary(Figure 2). The Web Soil Survey of Orono and Hennepin County classifies two soil types present on the subject property neither of which are hydric (Figure 3). Soil series descriptions are given in the Technical Documentation Section. The Minnesota Department of Natural Resources, State Protected Waters Map (Public Water Inventory),indicates no Public Waters present within the property boundary(Figure 4).
