Krell Property Wetland Determination and Delineation November 15,2005 Town of Verona,Dane County,Wisconsin NRC Project#05-260 RESULTS Table 1 is a list of the soils mapped in the Soil Survey of Dane County, Wisconsin,for the Property (Figure 2). Soils listed as hydric within Dane County are shown in bold print. Table I. Soil Map Units Identified at the Property.

WWI wetlands are shown on Figure 3. The Property is situated on the southwestern slope of a hill that forms the eastern edge of the floodplain of the Sugar River_ Topographic high areas on the Property are at 970 feet above mean sea level(msl)along County Highway PD and 950 feet msl along White Crossing Road. The ground slopes steeply to a low flat area of 930 feet elevation centered on an unnamed tributary of the Sugar River. This tributary discharges to the Sugar River approximately 1,300 feet south of the Property. The Sugar River is a tributary of the Pecatonica River,which discharges to the Rock River,a tributary of the Mississippi River. An onsite wetland determination and delineation was completed on November 15,2005 by Jerry Kelly of NRC. USACE data sheets were completed for sample points along transects through the wetland boundary plant communities,and are included in Appendix A. The transect and sample point locations were chosen within representative plant communities and at various landscape positions. Wetland A large wet meadow covers much of the central and western parts of the Property(Figure 4). Much of the wetland is a monoculture of reed canary grass(Phalaris arundinacea),but wetter areas support populations of hybrid cattail(Typha x glauca),and drier parts support prairie cordgrass(Spartina pectinata). Soils throughout much of the wetland are Otter silt loam,a mineral hydric soil. In the northwestern part of the wetland,the soils are a dark mineral silty clay loam of the Sable series. Evidence of wetland hydrology was generally limited to the presence of secondary indicators(soil survey data and the FAC-neutral test), although soils were saturated within 12 inches of the ground surface at one sampling location and other areas of observations.
