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 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 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 consist of a representative upland sample point and representative wetland sample point. Information obtained at the sample points can be found on the field data sheets 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 Cowardin et al. (1979) and used in the NWI (e.g. PEMB, PSS IC, 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 Wetland Plant List (Lichvar, et al. 2014. http✓/wetland plants usace.army,m . RESULTS The National Wetland Inventory does not indicate the presence of any wetlands on the property. (Figure 2a). The HCWI indicates no wetlands in the same location (Figure 2b). The DNR NWI update in 2014 shows one lacustrine waterbody, categorized as L2UBH, which stretches along the eastern boundary of the properties. (Figure 2c). The DNR 2014 update incorrectly maps an incursion of the L2UBH into the properties along the dividing property line for an approximate distance of 65 feet. The Web Soil Survey of Hennepin County (Figure 3) identifies two soil map units within the study area. They are Lester-Kilkenny soils and Udorthents. The Lester-Kilkenny soils are considered to be predominantly non-hydric and the Udorthents hydric classification is unknown. Soil series descriptions are provided in the Technical Documents section. The Minnesota Department of Natural Resources, State Protected Waters Map (Public Water Inventory) indicates one public water(PW 27-133) within the study area(Figure 4).
