BACKGROUND 8�METHODOLOGY <br /> BackQround <br /> As requested by Tim O'Connor, Anderson Engineering of MN, LLC completed a wetland investigation at <br /> the residential property located at 2625 North Shore Drive, Orono, Minnesota. <br /> Geographically, the site is located in Section 9, Township 117 North, Range 23 West. The wetland <br /> delineation was completed in accordance with the 1987 United States Army Corps of Engineers Wetland <br /> Delineation Manual and the published regional supplement to the Army Corps Wetland Delineation <br /> Manual, Midwest Region. <br /> The purpose of this study was to investigate the project area, identify areas meeting the technical criteria <br /> for wetlands, delineate the jurisdictional extent of the wetland basins, and classify the wetland habitat. <br /> Fieldwork for this site investigation was completed by Environmental Associates Kristina Justen and Alison <br /> Hruby on August 27,2015. The weather was sunny and 75 degrees Fahrenheit. <br /> Methodolos�v <br /> United States Geologic Service 7.5" Topographic Quadrangle maps, United States Fish and Wildlife <br /> Service National Wetland Inventory maps, United States Department of Agriculture Natural Resources <br /> Conservation Service Soil Survey and available aerial photographs were consulted to initially locate <br /> potential wetland habitats. <br /> Routine On-site Determination Method was used during this investigation. In this method, the following <br /> procedures were used: <br /> 1) The vegetative community was sampled in all present strata to determine whether it met <br /> hydrophytic vegetation criteria based on the indicators identified in the Midwest Regional <br /> Supplement. <br /> 2) Soil pits were dug using a Dutch auger to depths of 16"-36". Soil profile was noted, in addition to <br /> any hydric soil characteristics. <br /> 3) Signs of wetland hydrology were noted and compared to field criteria such as depth to shallow <br /> water table and depth of soil saturation found in the soil pits. <br /> Data from sample points were recorded on Army Corps of Engineers Midwest Region Wetland <br /> Determination Data Forms (Appendix 8). At least one sample point transect crosses the delineated <br /> wetland edge. This transect consist of an upland sample point and a wetland sample point. Other sample <br /> points may be located in areas which have one or more of the wetland vegetation, soils, or hydrologic <br /> characteristics present; where questionable conditions exist; or to verify the absence of wetland criteria. <br /> Photographs are also taken at each sample point, and of the wetland and upland buffer(Appendix C). <br /> Sample points were marked in the field with orange flags. The identified wetland boundary was marked <br /> with sequentially numbered pink flags. All sample points and the delineated wetland boundary were <br /> located utilizing a Trimble Geo XH sub-meter GPS unit. <br /> WETLAND�NVESTIGATION 4 <br /> 2625 NORTH SHORE DRIVE <br /> ORONO,MINNESOTA <br /> SEPTEMBER 2015 <br />
