Soils listed as hydric within Dane County are shown in bold print. Table 1. Soil Map Units Identified at the Property.

Based on the existing wetland and soil mapping information,an on-site wetland delineation was completed on April 25,2001. The on-site delineation identified one drainageway/wetland along the western boundary of the Property. Figure 4 shows the approximate location of the drainageway/wetlaoo area identified. USACE data sheets were completed for points on a transect through the wetland and adjacent upland, and are included in.Appendix A, Written descriptions of the wetlands,wetland boundaries,and adjacent uplands follow, Wetland I Wetland 1 is a drainageway/wetland located along the northwestern boundary of the Property. The dominant plant species observed at the sample point completed within Wetland 1 (sample point Pl)was willow(Salix sp,FACW/OHL)and red-osier dogwood(Cornus stolonifera,FACW). The soils in Wetland 1 were mapped as Houghton muck. The Houghton series consists deep,nearly levc , very poorly drained, organic soils on low benches and bottoms in stream valleys formed under sedge grasses. The soil conditions observed at the sample point completed within wetland I consisted of sediments with field indicators of hydric soil that included low chrome colors and an apparent aquic moisture regime, Wetland 1 appears to have a seasonally inundated/saturated hydroperiod fed by shallow groundwater and local surface water runoff. Three primary indicators of wetland hydrology, inundation,saturated soils within 12 inches of the surface,and watermarks were observed at the sample point within Wetland 1. Secondary indicators of wetland hydrology included local soil survey data and the FAC-neutral test. Natural Resources Consultin..Inc.
