Jacobson Environmental, PLLC www.jacobsonenvironmental.com <br /> Environmental Consultants Wayne Jacobson, P.S.S., W.D.C., P.W.S.,A.F.S. <br /> 5821 Humboldt Avenue North, Brooklyn Center, MN 55430 (612) 802-6619 Cell <br /> Email: jacobsonenv@msn.com <br /> 2) Soil pits were dug using a dutch auger to depths of 18"-40", noting soil profiles and any <br /> hydric soil characteristics. <br /> 3) Signs of wetland hydrology were noted and were compared to field criteria such as depth <br /> to shallow water table and depth of soil saturation found in the soil pits. <br /> Wetland edges were marked with orange numbered pin flags. 4-foot wood lath marked with orange <br /> "wetland boundary" flagging tape or flagging tied on vegetation may be used if site conditions warrant. <br /> Any wetlands were mapped by others using modern survey methods. At least one sample point transect <br /> crosses each delineated wetland edge. These transects consist of an upland sample point, and a <br /> wetland sample point. Other sample points may be located in areas which have one or more of the <br /> wetland vegetation, soils, or hydrologic characteristics present, or where questionable conditions exist. <br /> Sample points are marked with orange pin flags with a pink ribbon tied on them. Sample data sheets are <br /> found in Appendix B. <br /> Results <br /> Basin T <br /> Basin 1 is a PEMC Type 3 shallow marsh with a reed canarygrass fringe comprised of 15% narrowleaf <br /> cattail, 70% reed canarygrass, 5% black willow, 3% red osier dogwood, and 2%giant goldenrod, along <br /> with a few other species. The wetland boundary was typically a transition from kentucky bluegrass to <br /> reed canarygrass with a topographic break. The soils changed from dry Hamel soil to saturated Glencoe <br /> soil in the wetland. Soil saturation was present in the wetland, and hydrology disappeared in the upland. <br /> Basin 2 <br /> Basin 2 is a R3UB Type riverine wetland comprised of 90% narrowleaf cattail, 7% reed canarygrass, and <br /> 1%giant goldenrod with a few other species. The wetland boundary was typically a transition from <br /> common buckthorn to reed canarygrass with a topographic break. The soils changed from Hamel upland <br /> soil to Glencoe soil in the wetland. Soil saturation was present in the wetland, and hydrology disappeared <br /> in the upland. <br /> The National Wetland Inventory Map(NWI) (Figure 2) identifies no wetlands which were flagged on the <br /> subject site. <br /> According to the DNR Protected Waters Map (PWI) (Figure 4) of Hennepin County the site has no public <br /> waters on the site. Figure 5 shows the wetlands present on-site. Figure 6 is a parcel map of the area. <br /> According to the Web Soil Survey(Figure 3) the following hydric soils existed on the parcel: <br /> Hamel <br /> Glencoe <br /> Minnetonka <br /> Udorthents <br /> Photographs were taken of the site and some are included in Appendix C. <br /> Wetland Delineation-Mitigation-Permitting-Monitoring-Banking-Functional Analysis-T&E Surveys 13 <br /> Phase I Environmental Assessments-EAW's-Soil ID-Soil Analysis& Delineation-Environmental Referrals <br /> Pond &Lake Weed Control & Fish Stocking-Tree Surveys-Natural Resource Management Plans <br />
