wet]and boundaries." "...This Regional Supplement is designed for uso with thc current version of the Corps Manual (Envimnmenta] Laborstory 198'n and all subsequent versions. Where di$'erences 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 2014 aerial photographs were reviewed prior to the site visit ta identify areas that may be wetlands. Areas illutstrating evidence of wetland conditions were exa.mined in greater detail during the field survey. Vegetation, soils and hydrolagy were examined {as outlined in the 1987 Mazival) and used ta 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 cansist of a representative upland sample point, a representative transition sample point arfd representative wetland sample point. Information obtained at the sample points can be found on the field data sheets tocated in the Technical Documents section. Wetland boundaries were marke� at the site by pink"Wetland Delineation" pin flags and orange flagging tape. 'The wet[and 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 lacki.ng in one or more uf these criteria. Wetlands were classified in accordance with methods described by Cowatdin et al. (1979} and used ir� the NWI (e.g. PEMB, PSS1C, etc.), completed by the U.S. Fish and Wildlife Service. The Citeular 39 and Eggers and Reed classiftcation systems are also given. The indicator status of plants, as described in the Technir,al Documents section, was determined using the National List af P1ant Spocies That Occur in Wetlands—Region 3 (Sabine 1999). RESULTS The National Wetland Inventory indicates tYie presence ot two wetlands withi.n the survey area. (Figure 2a). These are classified as PEMC and PEMF/PSS1C. The DNR NWI update in 2014 maps the southern wetland (Wetland 5 as a PEM1F along with the wetland lobe along the shoreline of Tanager Lake{Figure 2b). Wetland 3 is mapped as PEM1F. Wetlands 2 and 4 are not mapped.The HCWI (Figure 2c)maps all of the wetlands hawever the configuration varies. The Web Soil Survey of Hennepin County (Figure 3) identifies seven soil map units present on the subject property many of which are within the same soil families. The Muskego, Blue Earth, and Houghton soil compiex is the only hydric soil listed onsite, while the only predominantly hydric and partially hydric soils listed onsite at the Hamel-Glencoe and Hamel, overwash-Hame1 complex, respectively. The remaining soils onsite are predominantly nonhydric and listed as Lester loam (6-12, 12-1$, and 25-35 percent slopes), Angus loam (2-5 percent slopes), Tadkee- Tadkee loam (0-3 percent slopes). Soil series descriptions are provided in the Technical Documents section.
