Wetland plant species nomenclature follows the "National List of Plant Species that Occur in Wetlands" (U.S. Department of the Interior, 1988). Regional field guides were used to confirm identification of plant species when deemed necessary. Soils were observed for hydric soil characteristics. Soils were examined by digging pits at representative locations and periodically along the wetland boundary. Pits were dug to a depth necessary to confirm hydric soil characteristics, up to a maximum depth of 24 inches. Soil color determinations were made using MUNSELL Soil Color Charts (Kollmorgen Instruments Corporation, 2000). Site soil characteristics were compared to those mapped and described in the Soil Survey for Hennepin County. Wetland boundaries were located and marked with sequentially numbered, pink "Wetland Delineation" pin flags. The locations of the pin flags were surveyed by Schoell Madson. The wetland edge is considered the highest extent of the wetland basin; areas above the boundary fail to meet the three required wetland parameters while areas below the edge meet the wetland parameters required by the field delineation methodology. The results of the delineation are presented at the end of this document. Wetland Classification Classification of the wetland basins are included on the (RODM) data sheets in Appendix A. Wetland classification follows the methods described in Wetlands and Deepwater Habitats of the United States (Cowardin, et al., 1979) and used by the U.S. Fish and Wildlife Service National Wetland Inventory. The Circular 39 classification (Shaw and Fredine, 1956)is also provided. Results The field delineation was conducted under normal temperature conditions and normal precipitation conditions as compared to the historical average for the region. Most of the vegetation was Ink identifiable, including all dominant species. One wetland area along the south edge of the peninsula was identified, delineated and classified. The (RODM) data forms indicate the dominant species of vegetation and the soil and hydrologic characteristics at a representative location around the basins. A review of the wetland delineation boundary line was conducted and field reviewed by Angela Hammers at the Minnehaha Creek Watershed District on---.
