Heinzeroth Property—Lot 2 Wetland Delineation Report Ms.Heinzeroth Town of Dunkirk,Dane County,Wisconsin November 7.2007 NRC Project#007-0238-01 At each observation point: 1. The presence or absence of normal circumstances was determined. 2. The plant community was characterized by identifying dominant plant species using the"50/20" rule. For each stratum in the plant community. dominant species are the most abundant(when ranked in descending order of abundance and cumulatively totaled)that immediately exceed 50%of the total dominance measure for the stratum, plus any additional species comprising 20%or more of the total dominance measure for the stratum. Wetland indicator status is ranked by percent probability of the species occurrence in wetlands as follows: OBL=Obligate Wetland, occurs with an estimated 99 percent probability of occurrence in wetlands FACW=Facultative Wetland,estimated 67 to 99 percent probability of occurrence in wetlands FAC=Facultative, equally likely to occur in wetlands and non-wetlands (34 to 66 percent probability) FACU= Facultative Upland, 67 to 99 percent probability in non-wetlands, 1 to 33 percent in wetlands UPL=Obligate Upland,greater than 99 percent probability in non-wetlands in this region NI=No indicator, insufficient information available to determine an indicator status Wetland indicator status can be modified with a positive sign(+)to indicate a frequency toward the higher end of the category, while a minus sign (-)indicates a frequency toward the lower end of the category(Resource Management Group, 1995); 3. Soil pits were typically dug to a depth of 18 inches and the soil was evaluated for hydric soil characteristics; and 4. Hydrology was assessed by observing for primary(i.e., inundation, saturation within the root zone, water marks, etc.)and secondary(i.e., oxidized pore linings,water-stained leaves,etc.)indicators of wetland hydrology. A transect was initiated at a representative location within each wetland for the wetland determination. The uppermost wetland boundary was identified once an upland site was encountered along the transect. The uppermost wetland boundary was flagged using consecutively numbered surveyors flagging. Subject to weathering,the flagging will remain in the field for use during a USACE/WDNR site visit and for a guide during construction.
