extending to the north. Similarly a Type 7 Wooded Swamp wetland basin has been designated on the MCWD FAW search in the South West corner of the parcel. There � . were no waterbodies on the property that show up on the DNR Public Waters Inventory (figure 4). � . � w . The Soil Survey of Hennepin County(figure 3) indicates that there are two soil series . present on the subject property. These soil series are: Hamel and Hayden. The Hamel soil . series is listed as hydric soil (SCS Hydric Soils of the United States) and is indicated in blue crosshatch on�figure 3. Soil series descriptions are located in Apppendix C. Site Visit MCWD staff examined the subject property for areas meeting jurisdictional wetland criteria during the site visit on May 16, 2007. It was a partly cloudy day in the 70's,the � site conditions were dry. One wetland meeting jurisdictional criteria was delineated along � the western parcel boundary. Detailed soils,vegetation, and hydrology data for the delineated wetland is provided in the data sheets of Appendix A. , Upon completion of the wetland delineation it has been determined that the wetland on the parcel is a Type 7 Wooded Swamp or a palustrine (P)type wetland with broad leaf deciduous forest cover(FO1) and saturated moisture regime (B), PFO1B wetland along � , the north and west perimeter of the site, see figure 5. The creek channel at the north side and the south east portion of the property has a clear channel in which the wetland.areas � � fall. Along the central portion of the property there is a gradual slope change leading up to the wetland edge. There were few areas where there was a drastic transition in the topography or the vegetation. Each transect was taken at locations where transitional areas were observed. The wetland basin was dominated by a tree canopy of Acer saccharinum(FACW) with an herb layer of Equisetum hyerriale (FACW-), Arisaema triphyllum(FACW-), Galium boreale (FAC) and Impations capensis (FACW-). There was little variation or vegetation . change along each transect, only a percentage change in dominance. Four sample points were taken along transect one. The transition between the upland and vvetland was not evident in the topography or the vegetation and therefore the soils and hydrology were used to make a determination. The wetland boundary was placed at the located where the soil saturation and hydrology changed � . Along transect one a dark {lOYR 2/1) clay loam overlaid a dark(2.SYR 2/1)to 17' at the wetland sample point. At the boundary location a thick layer of dark(lOYR 2/1) extended to 13". At the upland sample points a layer of brown(SYR 2.5/1) overlaid a layer�of brown (SYR 2.5/1)with few mottles (SYR 5/8). Based on the soil characteristics �. and a review of the official soil series descriptions the wetland sample is in the Hamel soil unit, as is the upland sampling point. Water was observed at 6"with saturation at 1" � at the wetland sample, saturation occurred at 11" at the boundary sample, and no saturated soils were observed at the upland sampling locations. � • �.
