Wetland Delineation Report <br /> Stonegate Farm,Orono&Medina, MN <br /> BES Project No. 2015-021 <br /> September 18,2015 <br /> Appendix B includes an aerial photograph with the location of each of the 16 areas evaluated <br /> for potential farmed wetlands. Table 1 in Appendix B summarizes the finding of the historical <br /> aerial photo review for each of the potential farmed wetland basins. A sample of the normal <br /> years photographs are also provided in Appendix B and all of the evaluated photos can be <br /> provided upon request. <br /> For the narrative section of this report the wetlands were grouped by similar characteristics. <br /> Representative characteristics of one of the wetlands are described here in the text. The <br /> detailed data for all of the sample points is included on the data sheets in Appendix C. <br /> Wetland A <br /> Wetland A is a large basin in the south 20 acres of the site. The basin includes the outlet <br /> drainageway to the west that has been broken into segments by two field crossings with <br /> culverts. Several areas along the wetland boundary extend out into the adjacent cultivated <br /> cropland. This basin is a Palustrine, Emergent, Seasonally flooded, drained (PEMCd) shallow <br /> marsh. Sample point SA-W in Wetland A is dominated by reed canary grass (Pha/aris <br /> arundinacea) and hummock sedge (Carex stricta). Cattail (Typha sp) dominates the center of <br /> the basin. The vegetation community met the dominance test and had a prevalence index of <br /> 1.58. Soils in the wetland consisted of six inches of N 2/0 muck, over nine inches of N 2/0 loam, <br /> over 2.5Y 6/2 sandy clay loam with 5/5 2.5Y 5/4 iron concentrations (Al2). Surface water(A1) <br /> 0-6+ inches was present in the basin at the time of the site visit. The water table (A2)was <br /> observed at a depth of nine inches and saturated soil (A3)was at four inches in the wetland soil <br /> pit. The other wetland hydrology indicator observed in the wetland included inundation <br /> saturation visible on aerial imagery(C9), geomorphic position (D2) and a positive FAC-neutral <br /> test(D5). The adjacent upland vegetation was sampled on a slight topographic rise in an area <br /> that was not cultivated in 2015. The upland is dominated by reed canary grass, smooth brome <br /> grass(Bromus inermis)and common ragweed (Ambrosia artemisiifolia). The vegetation <br /> community did not meet the dominance test and had a prevalence index of 3.38. The upland <br /> soils consisted of eight inches of N 2/0 loam, over N 2/0 clay loam (Al2). The water table (A2) <br /> was at a depth of 11 inches and saturated soil (A3)was at a depth of 6 inches in the upland soil <br /> pit after several days of heavy rain. No other wetland hydrology indicators were observed at the <br /> upland sampling point including the FAC neutral test. The wetland boundary was generally <br /> staked along the vegetation transition and topographic break. <br /> Wetlands B and C <br /> This group of wetlands are small, isolated, emergent wetlands in or along the upland forest. <br /> Wetland B was occasionally farmed in the past. Wetland B is described to represent the group. <br /> This basin is a Palustrine, Emergent, Seasonally Flooded, (PEMC) shallow marsh wetland. <br /> Sample point SB-W is dominated by reed canary grass with cattail in the center of the basin. <br /> The vegetation community met the dominance test and had a prevalence index of 2.02. Soils in <br /> the wetland consisted of 14 inches of 10YR 3/1 loam, over 10YR 4/1 clay loam with 10% 10YR <br /> 4/4 iron concentrations (Al2). Surface water(A1) up to three inches deep was present in the <br /> 3 <br />
