(NRCS), partially hydric means that "at least one component of the map unit is rated as hydric, <br /> and at least one component is rated as not hydric." Soil series descriptions are provided in the <br /> Technical Documents section. <br /> The Minnesota Department of Natural Resources, (Public Water Inventory) indicates no public <br /> water within the study area (Figure 4). This property is adjacent to public water located just <br /> outside the project boundaries. That public water is French Marsh(27-140P). <br /> Site Visit <br /> SER ecologists examined the subject property for areas meeting jurisdictional wetland criteria <br /> during the site visit. Two areas meeting the jurisdictional criteria of a wetland were flagged, and <br /> the boundary determined and delineated. The approximate wetland boundary is outlined in <br /> yellow(Figure 5). <br /> Wetland 1 is a Type 3 PEMCd shallow marsh. The vegetation at sample point 1-1 UP consisted <br /> of reed canary grass (Phalaris arundinacea, FAW), Kentucky bluegrass (Poa pratensis, FAC), <br /> and ground ivy (Glechoma hederacea, FACU). At sample point 1-1 WET the vegetation <br /> consisted of an herb layer of reed canary grass (Phalaris arundinacea, FACW) and broad leaf <br /> cattail (Typha latifolia, OBL). The transition from wetland to upland is characterized, in part, by <br /> this vegetative change. <br /> The soils at sample point 1-1 UP consisted of an initial 11 inches of 10YR 3/1 silt loam followed <br /> by a second horizon that was from 11-31 inches and was a 10YR 3/1 silt clay loam. The third <br /> horizon was from 31-36 inches and consisted of 10YR 4/1 sandy clay loam with 5 percent 7.5YR <br /> 4/6 redoximorphic concentrations in the matrix. The soils at sample point 1-1 WET consisted of <br /> an initial 12 inches of 10YR 2/1 silt clay loam followed by 12-16 inches of 10YR 2/1 silt clay. <br /> The third horizon was from 16-23 inches and had a 10YR 3/1 silt clay followed by 23-30 inches <br /> of 10YR 4/1 sandy clay loam with 5 percent 7.5 YR 4/6 redoximorphic concentrations in the <br /> matrix. Hydric soil indicator Al2 (Thick Dark Surface) was observed at the wetland sample <br /> point. <br /> Wetland hydrology was observed at sample point 1-1 WET. Indicators B6 (Surface Soil Cracks) <br /> and D2 (Geomorphic Position)were present. <br /> Wetland 2 is a Type 1/2 PFOA/PEMBd seasonally flooded basin and wet meadow wetland <br /> complex. Wetland 2 is a ditched flow-through wetland with hydrologic connections from the <br /> north and flowing down stream to the south. The ditched area extends in a north-south direction <br /> through the center of the basin along the west side of the tree line. The vegetation at sample point <br /> 2-1 UP consisted of Kentucky bluegrass (Poa pratensis, FAC) and ground ivy (Glechoma <br /> hederacea, FACU). At sample point 2-1 WET the vegetation consisted of green ash (Fraxinus <br /> pennsylvanica, FACW), buckthorn(Rhamnus cathartica, FAC), and an herb layer of reed canary <br /> grass (Phalaris arundinacea, FACW). The transition from wetland to upland is characterized, in <br /> part,by this vegetative change. <br /> Svoboda Ecological Resources Charles Cudd Builders <br /> Project Number: 2010-027 3 Orono,MN <br />
