The following text and attached data forms provide the required documentation for the delineation. WETLAND DELINEATION METHODOLOGY Wetland boundaries were delineated and flagged in the field by Westwood Professional Services on August 11, 1997 using the Corps of Engineers Wetlands Delineation Manual (Environmental Laboratory, Waterways Experiment Station, 1987). This manual is currently followed to delineate wetlands regulated under the Minnesota Wetland Conservation Act of 1991 and Section 404 of the Federal Clean Water Act. The level two routine delineation method u'as used in which sampling transects were established in a representative transition zone of each identified wetland. Transects consisted of one sampling point in obvious upland and one in obvious wetland. Soils, vegetation, and hydrology information were recorded at each point on data forms. Species dominance for vegetation measurements was based on the percent aerial or basal coverage visually estimated within a 30-foot radius for the tree and shrub layers and a five-foot radius for the herbaceous layer within the community type sampled. Prior to delineating the wetland boundaries in the field, National Wetlands Inventory (NWI) mapping, the Soil Survey of Hennepin County. Minnesota (USDA, 1974), and Department of Natural Resources (DNR) Protected Waters Mapping (1981) were reviewed. The soil survey shows the southern and western portions of the property mapped as Marsh with the remainder being Hayden loam and Cut and Fill Land. The NWI map shows nvo PEMF (Palustrine emergent, semipermanently flooded) wetlands in the southern portion of the site within the area designated as Marsh on the soil survey. The DNR Protected Wetlands Map for Hennepin County shows Protected Wetland 27- 014W on the southern half of the property roughly corresponding to the NWI-mapped wetlands. Wetland areas were classified according to Wetlands of the United States (U.S. Fish and Wildlife Service Circular 39; Shaw and Fredine, 1971) and Wetlands and Deepwater Habitats of the United States (FWS/OBS Publication 79/31: Cowardin et. al. 1979). Throughout the remainder of this report, wetland areas are identified first by their Circular 39 Classifications. Cowardin Classifications are included in
