3) Signs .of wetland hydrology were noted and compared to field criteria such as depth to <br />. shallow water table and depth of soil saturation found in the soil pits. <br />Wetland edges were marked with sequentially numbered 4-foot wood lath and flagged with <br />orange "wetland boundary" flagging tape. <br />Sample points were taken on the up Land.and wetland sides-of the boundary. Data sheets were <br />completed describing these sample points which ar~ representative of each wetland bqsin and its <br />corresponding upland. These data sheets are found ii1 Appenqix A. The wetland boundary <br />stakes and sample points.were surveyed in using a Trimble Ag 132 GPS equipped with a Juniper <br />Systems field data collector. This system produces sub-meter accuracy in the horizontal plane <br />t1sing real time differential correction. <br />Wetland .classification follows the methods used by the National Wet_lands Inventory. The <br />· Circular 39 classification is also given. <br />Results and Discussion <br />The National Wetland Inventory (Excelsior Quadrangle) had mapped one wetland on the north <br />and east according to Figure 1. The soil survey of Hennepin County indicates hydric soils are <br />beneath the site according to Figure 2. Figure 3 is the Minnesota Department of Natural <br />Resources Protected Waters map of Hennepin County which depicts no prot_ected water wetlands <br />on the subject property. · <br />Climatological data in the form of a.\YETS table analysis may prove useful if this wetland <br />boundary is contended, but at this fone WETS is not provided in our letter reports. <br />Figure 4 is an aerial photograph of the area with the wetland boundary and soil pit locations <br />shown on it. · · <br />Soil Pit Data Sheets with detailed sampling information-appear in Appendix A. Photographs of <br />wetland'basin #1 are presented in Appendix B. <br />Basin 1 . <br />Basin 1 is a Type 2 wet meadow vegetated principally by Reed Canarygrass and underlain by <br />peaty muck. The northern and northwestern boundaries of this wetland have receded due to lack <br />of hydrology which was lowered in the area over 20 years ago through channdization of the <br />· creek to the south and by installati~n of.a ditcl). system which appears on the 1991 aerial <br />pho_tographs, and exists today. <br />Iii
