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 2a), Hennepin County Wetland Inventory (HCWI) maps (Figure 2b), 2014 DNR NWI Update maps (Figure 2c), 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 no National Wetland Inventory wetlands present within the property boundary (Figure 2a). However, it is evident by aerial photography that portions of the mapped PUBF and L 1 UBH wetlands do encroach within the boundaries of the subject parcel. The NWI appears inaccurate within the subject area. The 2014 DNR NWI Update does show wetlands in those areas on the parcel, PEM1C to the northwest and L2UBH to eh south. The HCWI indicates no other potential wetlands in the area(Wetland 2c). The Web Soil Survey of Orono and Hennepin County classifies two soil complexes on the subject property (Figure 3). Both soil complexes are considered hydric soils. The soil series descriptions are given in the Technical Documentation Section. The Minnesota Department of Natural Resources, State Protected Waters Map (Public Water Inventory), indicates one Public Water wetland present within the property boundary (Figure 4).
